Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention in general relates to a cooler, in particular, to a manufacturing method of aligning heated faces of multiple heat pipes closely to form a coplanar configuration, and to a finished product and a fixture thereof. 
         [0003]    2. Description of Prior Art 
         [0004]    Accordingly, when a common heat pipe is applied as a cooling device for an electronic product, one side of the heat pipe is thermally connected to an electronic heating component, while another side is arranged by passing a plurality of cooling fins therethrough. Through the high thermal conductivity of the heat pipe, the heat generated by the electronic heating component can be transferred into each cooling fins via heat pipe, whereby the heat is dissipated into the ambiance, subsequently lowing down the temperature of the electronic component. In the meantime, the heat accumulated in each cooling fins can also be dissipated by means of cooling fans, thus an excellent cooling effect being able to achieve. 
         [0005]    Since the profile section of the heat pipe is substantially shown as a tubular configuration, its area is not big enough even after pressed flatly. Therefore, in a usual practice, the heat pipe is first connected to a thermally conductive plate, which is then attached onto the surface of an electronic heating component. However, in this kind of manner, it is impossible for the heat pipe to make a direct and close contact with the electronic heating component, thus the inherent performance of the heat pipe being unable to develop completely. On the one hand, since the thermally conductive plate is made of a material of copper, its weight is heavy and the purchasing cost is high. On the other hand, if the copper material is replaced by an aluminum material, which has a lighter weight, however, the thermally conductive performance will be influenced, because of its poor thermal conductivity. Therefore, a flatly rolled heat pipe is adapted by some practices; namely, the heated side of the heat pipe is formed as a flat configuration for facilitating a tight contact with the surface of an electronic heating component, as disclosed in a Taiwan Utility Model Publication No.: M248231 titled as “Heat Pipe Cooling Device”. 
         [0006]    Nonetheless, in flatly rolling a heat pipe according to the aforementioned method, on the one hand, when the flatly pressed area is small, the heated side of the heat pipe is insufficiently to cover the entire surface of the electronic heating component. On the other hand, in order to flatly roll out a sufficiently large area capable of thermal conduction, the tube will be broken when flatly rolled, if the thickness of the tubular wall can not stand the excessively rolling pressure. 
         [0007]    Accordingly, after a substantially devoted study, in cooperation with the application of relative academic principles, the inventor has finally proposed the present invention designed reasonably to possess the capability to improve the drawbacks of the prior arts significantly.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0027]    In cooperation with attached drawings, the technical contents and detailed description of the present invention are described thereinafter according to a number of preferable embodiments, not used to limit its executing scope. Any equivalent variation and modification made according to appended claims is all covered by the claims claimed by the present invention. 
         [0028]    The invention is to provide a manufacturing method, finished product and fixture of coplanar evaporators of multiple heat pipes. Mainly, after the evaporators  10  of the multiple heat pipes  1  are aligned closely to one another, a bonding media  12  is filled into the gaps among the heated faces  100  under each evaporators  10 , whereby each evaporators  10  are bonded together, making the bonding media  12  and each heated faces  100  formed into a coplanar configuration. 
         [0029]    Please refer to step S 1  of  FIG. 1 , also as shown in  FIG. 2 : first, providing a plurality of heat pipes  1 , each of which has an evaporator  10  and a condenser  11 . The evaporator  10  is adapted to contact a heat source, such as, an electric heating component (not shown in the figures), while the condenser  11  can be passed through by a plurality of cooling fins (not shown in the figures) for cooling purpose. There is a heated face  100  at the bottom face of the evaporator  10 . Making the heated face  100  contacted with the surface of the electronic heating component will increase the contacting area to each other and constitute a face-to-face thermal conduction. 
         [0030]    Please again refer to step S 2  of  FIG. 1 , also as shown in  FIG. 3 : each heat pipes  1  are aligned vertically with their evaporators  10  drawn closely; in the meantime, the heated faces  100  of each heat pipes  1  are laid on a flat face  200 . According to the invention, a fixture  2  is provided for positioning and combining each heat pipes  1 . The fixture  2  includes a platform  20 , a plurality of limiting blocks  21 ,  22 ,  23 ,  24  and a moudling  25 . The surface of the platform  20  has the flat face  200 , on which the plural limiting blocks  21 ,  22 ,  23 ,  24  are arranged, while each evaporators  10  is placed in the zone enclosed by each limiting blocks  21 ,  22 ,  23 ,  24  by making the heat face  100  located over the flat face  200 . 
         [0031]    Please again refer to step S 3  of  FIG. 1 , also as shown in  FIG. 3 : as described thereinbefore, the evaporators  10  of each heat pipes  1  can be undergone a limiting process via each limiting blocks  21 ,  22 ,  23 ,  24  from multiple directions, thus that each evaporators  10  is positioned by each limiting blocks  21 ,  22 ,  23 ,  24 , maintaining a configuration where each evaporators  10  is drawn and aligned closely. In this case, two pairs of the limiting blocks  21 ,  22 ,  23 ,  24  of the fixture  2  are formed, thus that the evaporators of the heat pipes  1  can be placed into the zone enclosed by the two pairs of limiting blocks  21 ,  22 ,  23 ,  24 . Therefore, a limiting function from four directions is provided by the four limiting blocks  21 ,  22 ,  23 ,  24 . 
         [0032]    Please again refer to S 4  of  FIG. 1 , also as shown in  FIG. 4  and  FIG. 5 : after the evaporators  10  of each heat pipes  1  are limited in the zone enclosed by each limiting blocks  21 ,  22 ,  23 ,  24 , the moudling  25  of the fixture  2  can load a pressure onto each evaporator  10 . In other words, each heated face  100  is pressed down onto the flat face  200  of the platform  20 , making the all heated face  100  flush with the flat face  200 . In this case, there is a nozzle  250  arranged on the top face of the moudling  25  and overriding the two limiting blocks  23 ,  24  opposite to each other. The two limiting blocks  23 ,  24  respectively has a screwing hole  230 ,  240 , corresponded to each of which the moudling  25  is arranged a perforation  251 . Furthermore, a specific screwing component  252 , such as, stud, can be adapted by penetrating the perforation  251  and being screwed in the screwing hole  230 ,  240 , whereby the moudling  25  is fixed on the two limiting blocks  23 ,  24  and presses each evaporators  10  down onto the platform  20 . 
         [0033]    Finally, please refer to S 5  of  FIG. 1 , also as shown in  FIG. 6  and  FIG. 7 : via the nozzle  250  on the moudling  25 , a specific boding media  12 , such as, solder, is injected into the gaps among the heated faces  100  of each evaporators  10 . In this step S 5 , the boding media  12  shown as a thick fluid flows around by filling the gaps among each evaporators  10 . Via the flat face  200  of the platform  20 , a connection face  120  is formed among each heated faces  100 . Since the connection face  120  is configured through a match-up with the flat face  200 , the connection face  120  is substantially a flat face as well. In addition, since each heated faces  100  is flush with the flat face  200  of the platform  200 , the connection face  120  and each heated faces  100  constitute a coplanar configuration. 
         [0034]    Moreover, after the evaporators  10  of each heat pipes  1  are bonded together, in order to keep the condensers  11  of each heat pipes  1  maintaining an arrangement of being interspaced to one another and facilitating the cooling fins to pass therethrough, in the step S 1  or S 2 , the condensers  11  of each heat pipes  1  can be commonly arranged a spacer  26 , on which a plurality of positioning holes  260  are arranged by corresponding to the disposition of each condensers  11 , thus that the condensers  11  still can maintain an arrangement of being interspaced to one another, under the condition that the evaporators  10  of each heat pipes  1  can be drawn and aligned closely. In addition, since the platform  2 , each limiting blocks  21 ,  22 ,  23 ,  24 , the moudling  25  and the spacer  26  of the fixture  2  are all constituted by the materials of temperature-enduring fibers or ceramics, when the bonding media  12  is heated in the oven, the fixture  2  can stand high temperature and has sufficient strength to maintain each evaporators  10  with fixed position and configuration. 
         [0035]    Therefore, through the constitution of aforementioned assemblies, a manufacturing method, finished product and fixture of coplanar evaporators of multiple heat pipes according to the invention are thus obtained. 
         [0036]    In addition, as shown in  FIG. 8  and  FIG. 9 , each limiting blocks  21 ,  22 ,  23 ,  24  of the fixture  2  can also be classified into two groups: one is fixed type, and the other is movable type. Taking the embodiment proposed by the invention as an example, the quantity of the limiting blocks  21 ,  22 ,  23 ,  24  is four, so two pairs of opposite directions are formed after enclosed into a zone. In the two pairs of limiting blocks  21 ,  22 ,  23 ,  24 , any two limiting blocks opposite to each other in one pair are either a fixed type or a movable type. With respect to the pair of the limiting blocks  21 ,  22  arranged in longitudinal direction, the platform  20  is arranged a slide  201  on the flat face  200 , such that a slip part  220  is arranged under the limiting block  22  and can be slipped in the slide  201  correspondingly. On the other hand, with respect to the pair of the limiting blocks  23 ,  24  arranged in crosswise direction, another slip part  241  can be arranged under the limiting block  24  and slipped in the slide  201  correspondingly. Thereby, by adjusting the distance between any two limiting blocks opposite to each other, the evaporators  10  of different quantities or different radiuses can be all placed therein after being drawn and aligned closely to one another. 
         [0037]    Therefore, in the manufacturing method, the finished product and the fixture of the coplanar evaporators of the multiple heat pipes according to the invention, the evaporators  10  of the multiple heat pipes  1  can be drawn closely to one another and fixed by a bonding media  12 , thereby, the heated faces of each evaporators  10  being able to be formed into a coplanar configuration with a larger area of heat conduction, which can entirely cover the surface of the electronic component and be attached closely thereto, so the evaporator  10  of the heat pipe  1  can be directly contacted with the electronic heating component to undergo a heat transfer process. 
         [0038]    Summarizing aforementioned description, the manufacturing method, the finished product and the fixture of the coplanar evaporators are indispensable invention for multiple heat pipes indeed, which may positively reach the expected usage objective for solving the drawbacks of the prior arts, and which extremely possesses the innovation and progressiveness to completely fulfill the applying merits of a new type patent, according to which the invention is thereby applied. Please examine the application carefully and grant it as a formal patent for protecting the rights of the inventor. 
         [0039]    However, the aforementioned description is only a number of preferable embodiments according to the present invention, not used to limit the patent scope of the invention, so equivalently structural variation made to the contents of the present invention, for example, description and drawings, is all covered by the claims claimed thereinafter.
