     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to cooling system that is modular in design, has integrated cooling components and that can be selectively used in mobile and/or stationary environments. 
     2. Description of the Related Art 
     Cooling of electronic equipment is a major concern for proper operation of the equipment. No matter the equipment type (servers, telecommunication, medical imaging devices, acoustic components, circuits and/or otherwise), heat dissipation is a primary design and operational concern. Fortunately, many solutions are available when the equipment is used in a stand alone environment. One solution is to rely on the ambient air to cool the equipment. On board fans may provide convective cooling in this endeavor. 
     However, when density of the electronic equipment is increased, the challenge of keeping the equipment within preferred operational temperatures also increases. The challenge of operating at a consistent and low temperature in order to maximize equipment life also increases with the density. 
     In one particular situation, there is a desire to have many servers confined within a single space. Such a space is typically called a server room on a small scale and a data center on a larger scale. There is a need to have modular server rooms and data centers that can be expanded as the user&#39;s requirements grow. There is also a need to have a mobile server room or data center that can be transported from one location to another (from simply across a facility to all the way across international boundaries). There is, as of yet, not been a solution that provides acceptable cooling results. 
     Thus, there exists a need for a modular integrated cooling system that solves these and other problems. 
     SUMMARY OF THE INVENTION 
     The present invention relates to cooling system that is modular in design, has integrated cooling components and that can be used and easily transported in a mobile environment and/or used in a stationary environment. 
     According to one embodiment of the present invention, a system is provided having a foundation that is modular in design. The foundation is structural with a transport structure, such as fork pockets. Removable floor sections are also provided. A load bearing surface such as a plate can be provided on top of isolators and supported on the foundation. A skeleton can be constructed on top of the foundation. The skeleton supports the heat exchanger assembly, which includes a plenum, a heat exchanger and air movers. A ducting assembly with boxes is supported by the skeleton. An equipment rack, such as a server rack, can be supported on the bearing plate. Any number of systems can be attached end to end to form a system of a desired length. The entire system, once assembled and wired, can easily be conjoined or moved to a desired destination such as a container. The system can also be expanded in size and capacity as the operational needs increase. 
     According to one advantage of an embodiment of the present invention, the system is scalable in that it can be expanded after it is operational. In this regard, the system is scalable as necessary when necessary. 
     In another preferred embodiment, the modules can be attached back-to-back, side-to-side, and/or vertically. 
     In still another preferred embodiment, a translating load bearing surface can be provided to allow translation of equipment within the module relative the foundation or stationary floor. Advantageously, access for maneuverability, serviceability and/or electronic component replacement is enhanced. Specifically, and without limitation, a full depth server can be replaced within the present invention. Also, the location of the components within the module can be precisely situated for optimum heat dissipation. 
     According to another advantage of the present invention, the structure can be made of a variety of materials selected for strength, weight and economic reasons. Two such materials are steel and aluminum. 
     According to another advantage of the present invention, each assembly is designed for individual or modularly linked uses. When a linked assembly is provided, each individual foundation is simply connected together with bolts or other types of removable fasteners in an end to end longitudinal arrangement, in a back-to-back arrangement, and in addition to or as an alternative to, in a vertically stacked arrangement. 
     According to a still further advantage of an embodiment of the present invention, the equipment can first be installed onto a load bearing surface, and then the walls can be put in place. The electronic equipment can be assembled and wired when the foundation is outside of a container. A fork lift or other transport device such as an overhead lift can then be used to move the full assembly into a container after assembly is accomplished. One of many possible containers is a HI-Cube ISO container. Yet, it is appreciated that the principles of the present inventions can be applied and incorporated into a design involving many different types of containers, including, without limitation, standard shipping containers, rail cars and on site drop over covers. Still further, the present invention can be fitted with insulated wall panels for stand-alone applications independent of an external container without departing from the broad aspects of the present invention. 
     According to a still further advantage yet of the present invention, the equipment is segregated from the cooling elements. This is accomplished in some embodiments of the present invention by locating the ducting and heat exchanger within the walls, and running the piping under floor sections. Related, the floor sections can be removable and can have openings there through. This advantageously allows for any liquid to fall through the openings and be collected remote from the equipment. Thus, there is a decreased risk of liquid coming into contact with the electronics. 
     According to still further advantage yet of one embodiment of the present invention, a hot aisle and a cold aisle can be provided within each module. This advantageously allows workers to have access to both sides of the equipment even when the equipment is located inside a container. 
     According to a still further advantage yet of a preferred embodiment of the present invention, two modules can be fixed in a back-to-back orientation. This advantageously allows for two cold aisles and one hot aisle to be defined and for common elements (of former distinct hot aisles) to be eliminated. 
     According to still further advantage yet of the present invention, isolators are provided for protecting the equipment from vibrations and shocks. One type of isolator can comprise a pair of springs. 
     According to still further advantage yet of the present invention, a full stratification of cooled air can be achieved to improve equipment cooling. This can be accomplished through the use of the geometry of the natural currents and forced air apparatuses when necessary. 
     According to a still further advantage of the present invention, several modes of operation can be utilized. For example, the air can be re-circulated, cooled (examples such as direct cooling and direct expansion), humidified, or simply drawn and filtered from the environment and passed through the system and/or a combination or mixture thereof, as desired. In one operational embodiment where a combination of these modes is desired, a real time feedback control can be used to sense environmental conditions and make electro-mechanical adjustments to the system to achieve necessary and desired heat dissipation. 
     According to still further advantage yet of an embodiment of the present invention, the ducting can comprise clear panels that allow light to pass through. 
     Other advantages, benefits, and features of the present invention will become apparent to those skilled in the art upon reading the detailed description of the invention and studying the drawings.

The bearing plate  50  is preferably located intermediate two strips of floor sections. However, it is understood that in alternative embodiments, such as a three aisle configuration, could be provided without departing from the broadest aspects of the present invention. It is understood that a three aisle configuration can have two independent bearing plates. 
     Turning now to  FIGS. 1 and 10 , a preferred embodiment of isolators  60  is shown. Each isolator  60  has a top  61 , a bottom  62  and is comprised of a pair of coil springs. The springs  63  each have a longitudinal axis that is preferably oriented generally vertically and are located within the foundation  20 . The isolators  60  preferably mechanically isolate the bearing plate  50  from shocks and vibrations impacting the foundation  20 . 
     Now looking at  FIGS. 1, 9 and 18 , it is seen that a translation assembly  70  is provided. The translation assembly  70  has a base  71 , a track  72 , rollers  73  with inverted V-shaped perimeters  74 , a carrier  75  and a pin  79 . The track is preferably linear, and generally has a converging shape similar to an inverted V. One or more rollers  73  are guided by and roll on the track  72 . The rollers  73  have a perimeter  74  that are shaped to mate with the track to maintain linear tracking and stability. The carrier  75  can have a first vertical section  76  and a second vertical section  77 , and a horizontal section  78  between the vertical sections. The vertical sections are preferably generally parallel to each other, and are preferably generally perpendicular to the horizontal section. The carrier  75  is preferably connected to the rollers  73  with pins  79 . In a preferred embodiment, three rollers  73  are used. However, it is understood that more or fewer rollers can be used without departing from the broad aspects of the present invention. 
     The horizontal section  78  of the carrier  75  fits within and extends through the openings  46  in floor section  45 . The openings  46  are wider than the carrier  75 , wherein the carrier can move, or translate, within the opening. The horizontal sections  78  are connected to the bottom  52  of the bearing plate  50  wherein the bearing plate is movable relative the foundation  20 . 
     Comparing  FIGS. 6 and 7 , it is seen that the bearing plate  50  is translated between a first position and a second position relative to the foundation  20 . The translation assembly allows the operator to selectably access items in the module on both sides of the bearing plate  50 . It is appreciated that the operation of the translation assembly can be manual or automated. 
     Turning now to  FIGS. 3, 4, 6 and 7  in particular, a preferred skeleton  90  is illustrated. Skeleton  90  is preferably comprised of several uprights  91 , each having a top  92  and a bottom  93 . The uprights  91  are preferably generally parallel to each other and perpendicular to the C shaped channels  30  and  32 . Cross members  95  are also provided. The cross members  95  each have ends  96  and  97 , respectively, and are preferably generally parallel to each other perpendicular to the uprights  91 . The cross members  95  can comprise angle members with a vertical section and horizontal sections. The cross members  95  can be arranged in pairs having opposing inward facing horizontal sections that support ductwork boxes (described below). Wiring and other items may be routed through conduit  98 . 
     Piping  100  and  105 , such as tubes or lines, are provided and can best be seen in  FIGS. 1, 3 and 4 . The piping can contain hydraulics, water, coolant, or other gasses or fluids which can be used as a cooling medium or material for the heat exchanger. The piping can be used for other reasons as well. The piping  100  and  105 , as illustrated, can be routed through the passages  36  formed by the joists  35  under the removable floor sections  40  and  41 . Any leaks will be contained below the floor  40 ,  41  and  42  and remote from the equipment. 
     Looking now at  FIGS. 2, 5, 7 and 8  in particular, it is seen that a preferred heat exchanger assembly  110  is provided. The heat exchanger assembly  110  can have a plenum  120 , a heat exchanger  130 , one or more fans  140  and one or more panels  145 . It is understood that the location of the heat exchanger assembly is preferably on the side of a module  10 , allowing for easy plumbing and servicing. 
     Plenum  120  has a top  121  and a bottom  122 , a side  123  and a second side  124 , a first wall  125  and a second wall  126 . The first wall is preferably on the inner side of the assembly  110 , and the second wall  126  is preferably on the outer wall of the assembly. The plenum  120  houses the heat exchanger  130  and also collects any condensate material. 
     Now turning to  FIG. 8 , it is seen that the heat exchanger  130  has a top  131 , a bottom  132 , a first side  133 , a second side  134  a front  135  and a back  136 . An inlet  137  and an outlet  138  are provided. Both the inlet  137  and the outlet  138  can be located at the bottom  132  of the heat exchanger  130 . In this regard, the heat exchanger can preferably have a front section wherein the coolant moves upward, and a rear section wherein the coolant moves downward. In this regard, the air moving across the heat exchanger passes through both the front section and the rear section. Of course, more than one heat exchanger may be utilized without departing from the broad aspects of the present invention. Also, the heat exchanger may be configured differently, such as a horizontal heat exchanger with fittings located generally at the heat exchanger ends without departing from the broad aspects of the present invention. 
     Fans  140  are provided, as are panels  145  as illustrated in  FIGS. 7 and 8 . While fans are illustrated, it is understood that any suitable type of air mover may be utilized without departing from the broad aspects of the present invention. The panel  145  is preferably hinged with a hinge  146  for allowing access behind the panel  145 . It is understood that louvers or diffusers could be incorporated adjacent the fans to direct the air as it leaves the heat exchanger assembly  110 . 
     Turning now back to  FIGS. 1 and 2 , it is seen that a ductwork or ducting assembly  150  is provided. The ducting assembly  150  has several boxes  160 ,  170  and  180 , as well as a collector  190 . The ducting is preferably integrated into the perimeter of the system or module  10 . Each box can define a channel. It is understood that more or less than channels may be used without departing from the broad aspects of the present invention. It is appreciated that the ducting intakes, described below, are at the top of the module  10  to take advantage of the natural buoyancy of the warmed air. 
     Box  160  has a first end and a second end, and a first side and a second side. An inlet  165  is at the first end and an outlet  166  is at the second end. Further, a crossover outlet is near the second end and directs a portion of the air to enter the center box  180 . Box  160  further has a top panel and a bottom panel, and generally has a rectangular cross-section. The top and the bottom panels can be transparent, such that light can pass there through. A fan  168  or other type of air mover can force air into the inlet  165 . 
     Box  170  has a first end and a second end, and a first side and a second side. An inlet  175  is at the first end and an outlet  176  is at the second end. Further, a crossover outlet is near the second end and directs a portion of the air to enter the center box  180 . Box  170  further has a top panel and a bottom panel, and generally has a rectangular cross-section. The top and the bottom panels can be transparent, such that light can pass there through. A fan  178  or other type of air mover can force air into the inlet  175 . 
     Box  180  has a first end and a second end, and a first side and a second side, and is preferably located between box  160  and box  180 . An inlet  185  is at the first end and an outlet. Further, crossover inlets are near the second end and receive a portion of the air exiting crossover outlets  166  and  176  of boxes  160  and  170  respectively. Box  180  further has a top panel and a bottom panel, and generally has a rectangular cross-section. The top and the bottom panels can be transparent, such that light can pass there through. A fan  188  or other type of air mover can force air into the inlet  185 . 
     Now looking at  FIGS. 1, 2, 11 and 12 , it is seen that a collector  190  is provided for collecting the air from the boxes  160 ,  170  and  180 . The collector  190  has a top, a bottom, sides, and ends. Inlets  197  are provided for collecting air as it passes through outlets  166  and  176  of boxes  160  and  170 , respectively and also through outlet recessed within box  180 . A single outlet  198  is preferably provided, and discharges the air into the top  121  of the plenum  120 . 
     An equipment rack  200  can be positioned upon the bearing plate  50 , as seen in  FIGS. 1, 3-5, 16 and 17 . The rack  200  can have sides, a front  201  and a back  202 . One type of rack is a server rack. However, it is appreciated that other types of racks for other types of equipment needing to be cooled can be used without departing from the broad aspects of the present invention. It is appreciated that while an equipment rack is illustrated, it is not intended to be limiting in any way. Any cabinet or other structure may be utilized without departing from the broad aspects of the present invention. It is further appreciated that the broad aspects of the present invention are applicable even in embodiments without a traditional rack. 
     Turning now to the air flow of the illustrated preferred embodiment, and looking at  FIG. 17 , the arrows depict a stratified air flow (cool low, hot high). The air enters the cool aisle  215  and passes through the equipment rack  200 . In an embodiment where servers are cooled, the existing fans on board the servers or other equipment can, but need not, help move the air across the equipment. In this regard, the fans  140  of the present invention can provide sufficient air flow to keep any equipment within the modules cool. The air gains heat from the equipment and then enters the hot aisle  210 . The buoyancy of the warmer air tends to cause it to rise. Fans  168 ,  178  and  188  assist, pull or direct the air into the ducting assembly  150 , where it passes through boxes  160 ,  170  and  180 , and into the collector  190 . The air enters the plenum  120  and passes through the heat exchanger  130  to cool before passing through fans  140  and back into the cool aisle  215 . 
     Looking now at  FIG. 16 , it is seen that an embodiment drawing external environmental air through the module  10  is illustrated. A fresh air intake  220  with a filter is provided and an exhaust  225  to the environment is provided. The fresh air enters into the cold aisle  215 , passes through the equipment, enters the hot aisle  210 , and then exits through exhaust  225 . Environmental conditions can be used to the advantage of the operator when the ambient environmental air temperature is less than the air temperature after the air passes through the equipment held in the equipment rack. In this regard, the ambient environmental air would be cooler than the otherwise recirculated air, and would require less cooling (compared to the recirculated air) to achieve the desired cold aisle temperature. 
     It is understood that during operation, the operator can select either the flow shown in  FIG. 16  or the flow shown in  FIG. 17 , or a combination of both. Staying with  FIG. 16 , it is seen that several distinct heat exchangers, including a direct cooling heat exchanger  130 , a direct expansion heat exchanger  226  and an evaporative heat exchanger  227  can be housed within the plenum. Each of these heat exchangers can be independently used, or as an alternative, used in combination with filtered fresh ambient air. In this regard, a real time feedback control can be used to sense environmental conditions and make electro-mechanical adjustments to the system to direct the necessary flow paths to achieve the desired amount of heat dissipation. 
     Looking now to  FIG. 19 , it is seen that walls  230  can be provided. The walls can contain insulation or material with other desirable attributes, namely noise reduction, protection from the elements and structural enhancement among others. The walls can be attached to or supported by the skeleton  90 . One preferred method of removably attaching the walls or panels is with bolts. Walls can be used when the module  10  is intended for use as a stand-alone structure, as well as when the modules are scaled and housed in a container in order to act as a skin to maintain desired air flow characteristics. 
     Now turning to  FIG. 13 , it is seen how several modules can be assembled end to end to form a complete assembly. While bolts are a preferred connector, it is understood that other connectors may be used without departing from the broad aspects of the present invention. A ½ module  10 X is shown to be longitudinally connected to modules  10 ,  10 A,  10 B,  10 D and  10 E. In this embodiment, an information technology pack is shown with several modular sever racks linked in an end to end relationship. The ½ module can be a utility module. The complete assembly is able to be moved into a container  240  with a transport assembly. 
     It is understood that modules of distinct purposes could be modularly connected to create solutions to alternative situations as well.
