Description:
BACKGROUND OF THE INVENTION 
       [0001]    a) Field of the Invention 
         [0002]    The present invention relates to a memory cooling device, and more particularly to a cooling device which is able to improve a heat dissipation efficiency of a memory or a chip, thereby increasing a lifetime of usage for the memory or chip. 
         [0003]    b) Description of the Prior Art 
         [0004]    A conventional heat dissipation structure for a memory is disclosed in the Taiwanese Utility Model Patent No. M298165, wherein connection sections of a heat pipe are inserted into arc-shape grooves of a connection seat, and a cross-over member is used to clamp a memory. However, under a long term usage, the structure is provided with following shortcomings:
       (1) As shown in  FIG. 2  and  FIG. 4  of the prior art, when the memory generates heat, the heat is first transmitted to the aluminum-extrusion connection seat, and is then transmitted to the heat pipes from the arc-shape grooves of the connection seat. Therefore, the heat is indirectly transmitted from the heat pipes to result in an inferior heat transmission effect, thereby prohibiting the heat of the working memory from being transmitted and dissipated efficiently and quickly.   (2) Inner walls of the cross-over member directly clamp the memory, and surfaces where the two elements are fitted are provided with gaps, rough surfaces, or capillaries, which will induce an inferior heat dissipation effect.       
 
       SUMMARY OF THE INVENTION 
       [0007]    The primary object of the present invention is to provide a memory cooling device such that by a straight surface at a side of a heat pipe, and by affixing at least one layer of thermal adhesive on a surface of a memory, operating temperature of a working memory can be transmitted directly to the heat pipe and a left and a right clamping seat by the thermal adhesive, to provide a higher heat dissipation rate of the memory and more actual and efficient heat dissipation, thereby improving a lifetime of usage for the memory. 
         [0008]    Another object of the present invention is to provide a memory cooling device such that by using the thermal adhesive as a connection interface between an outer wall of the heat pipe and the memory, the heat dissipation effect of the memory can be further improved.

         [0020]    Heat generated from the bottom surface  42  of the memory  40  can be transmitted to the clamping surface  121  of the left clamping seat  12  through the first thermal adhesive  30 . 
         [0021]    The first heat pipe  20  is provided with a second straight surface  24  at a location opposite to the first straight surface  22 , and the second straight surface  24  is latched to and in touch with a groove wall  125  (as shown in  FIG. 3 ) of the groove  123 . 
         [0022]    The first heat pipe  20  is in a U shape and is disposed with an outer pipe  21 . A surface of the outer pipe  21  is latched with cooling fins  211  (as shown in  FIG. 1 ). 
         [0023]    Outer surfaces of the left and right clamping seats  12 ,  14  are provided with cooling gills  126 ,  146 . 
         [0024]    Referring to  FIGS. 4 to 6 , the present invention is to provide a memory cooling device, including a left clamping seat  12  which is provided with a lower clamping surface  121  and a higher fixing interface  122 , with the clamping surface  121  being disposed with a groove  123 ; a first heat pipe  20 , at least one side of which is formed with a first straight surface  22 , and which is latched into the groove  123 , with a first thermal adhesive  30  being affixed on the clamping surface  121  and the first straight surface  22 ; a memory  40 , a bottom surface  42  of which is affixed on a surface of the first thermal adhesive  30 ; a second thermal adhesive  30 ′ which is affixed on an outer surface  44  of the memory  40 ; a right clamping seat  14  which is provided with a lower clamping surface  141  and a higher fixing interface  144 , with the clamping surface  141  being disposed with a groove  147 ; and a second heat pipe  20 ′, at least one side of which is formed with a first straight surface  22 ′, and which is latched into the groove  147 , with the second thermal adhesive  30 ′ being affixed on the clamping surface  141  and the first straight surface  22 ′. 
         [0025]    The outer surface  44  of the memory  40  is affixed on a surface of the second thermal adhesive  30 ′, the fixing interface  144  of the right clamping seat  14  is connected and fixed with the fixing interface  122  of the left clamping seat  12 , and the left and right clamping seats  12 ,  14  clamp and affix the memory  40  and the first and second heat pipes  20 ,  20 ′ respectively. Operating temperature generated by the memory  40  is transmitted to the first thermal adhesive  30  from the bottom surface  42 , and is then directly transmitted to the first straight surface  22  of the first heat pipe  20 ; whereas, the operating temperature generated by the memory  40  is transmitted to the second thermal adhesive  30 ′ from the outer surface  44 , and is directly transmitted to the first straight surface  22 ′ of the second heat pipe  20 ′ for cooling. 
         [0026]    The first thermal adhesive  30  can be coated in a glue shape on the clamping surface  121  of the left clamping seat  12 , and the first straight surface  22 , allowing the bottom surface  42  of the memory  40  to be affixed into the first thermal adhesive  30 . 
         [0027]    The second thermal adhesive  30 ′ can be coated in a glue shape on the clamping surface  141  of the right claming seat  14 , allowing the outer surface  44  of the memory  40  to be affixed into the second thermal adhesive  30 ′. 
         [0028]    Referring to  FIG. 6 , the first and second heat pipes  20 ,  20 ′ are provided with second straight surfaces  24 ,  24 ′ at locations opposite to the first straight surfaces  22 ,  22 ′. The two second straight surfaces  24 ,  24 ′ are latched into and in touch with groove walls  125 ,  148  of the two grooves  123 ,  147  respectively. 
         [0029]    The fixing interface  122  of the left clamping seat  12  is provided with connection holes  124 , the fixing interface  144  of the right clamping seat  14  is provided with connection holes  145 , and bolts  50  are screwed into the connection holes  145 ,  124 , to connect the left and right clamping seats  12 ,  14  into one body. 
         [0030]    Temperature generated from the bottom surface  42  of the memory  40  can be transmitted to the clamping surface  121  of the left clamping seat  12  through the first thermal adhesive  30 ; whereas, temperature generated from the outer surface  44  of the memory  40  can be transmitted to the clamping surface  141  of the right clamping seat  14  through the second thermal adhesive  30 ′. 
         [0031]    Referring to  FIGS. 1 to 3 , the left and right clamping seats  12 ,  14  of the present invention clamp the single first heat pipe  20 . In other words, temperature of the bottom surface  42  of the memory  40  is transmitted to the first heat pipe  20  and the left clamping seat  12  for cooling, through the first thermal adhesive  30 . As the first straight surface  22  is a horizontal and straight surface, and the first thermal adhesive  30  is plastic, the first thermal adhesive  30  can be uniformly affixed on the first straight surface  22  and the clamping surface  121 . In addition, the first thermal adhesive  30  can be also uniformly affixed on the bottom surface  42  of the memory  40 , due to its plasticity. Therefore, when the memory  40  generates heat from operating, its temperature can be uniformly transmitted to the first thermal adhesive  30 , and then transmitted to the first straight surface  22  and the clamping surface  121  from the first thermal adhesive  30 , enabling temperature generated from the bottom surface  42  of the memory  40  to be cooled down through the left clamping seat  12  and the first heat pipe  20 . The outer surface  44  of the memory  40  and the plastic second thermal adhesive  30 ′ are affixed uniformly, and the second thermal adhesive  30 ′ and the clamping surface  141  are affixed uniformly, enabling heat generated from the outer surface  44  to be transmitted to the right clamping seat  14  through the second thermal adhesive  30 ′. 
         [0032]    The first straight surface  22  of the first heat pipe  20  is affixed on the bottom surface  42  by the first thermal adhesive  30 . As a design of the first straight surface  22 , heat conduction area is enlarged. Due to that the first thermal adhesive  30  is plastically (can be filled) affixed to surface capillaries of the first straight surface  22 , surface capillaries of the clamping surface  121 , and capillaries of the bottom surface  42 , an efficiency of transmitting heat from the bottom surface  42  to the first straight surface  22  is completely improved, thereby increasing the heat dissipation efficiency. 
         [0033]    The second thermal adhesive  30 ′ is plastically (can be filled) affixed on surface capillaries of the clamping surface  141 , and is plastically affixed on the outer surface  44 , enabling heat on the outer surface  44  to be efficiently transmitted to the right clamping seat  14  for cooling. Its heat dissipation efficiency is apparently improved from the affixing of the second thermal adhesive  30 ′. Furthermore, fins  211  are used to enhance the effect of heat dissipation for the first heat pipe  20 , and the gills  126 ,  146  also improve the effect of heat dissipation. 
         [0034]    Referring to  FIGS. 4 to 6 , the left and right clamping seats  12 ,  14  of the present invention clamp the first and second heat pipes  20 ,  20 ′. In other words, for the single memory  40  with higher operating temperature, heat can be directly dissipated through the two heat pipes  20 ,  20 ′ respectively, to improve the heat dissipation efficiency. The groove  147  of the right clamping seat  14  is latched with the second heat pipe  20 ′, and then by affixing the second thermal adhesive  30 ′ on the outer surface  44  of the memory  40 , and the first straight surface  22 ′ of the second heat pipe  20 ′, the bottom surface  42  and the outer surface  44  of the memory  40  can be further used as intermediate heat transmission media to improve the heat transmission efficiency for the first and second heat pipes  20 ,  20 ′, through the first and second thermal adhesives  30 ,  30 ′ respectively. 
         [0035]    Furthermore, the first and second heat pipes  20 ,  20 ′ are latched respectively into the grooves  123 ,  147 , and also transmit the heat to the left and right clamping seats  12 ,  14  for cooling, upon transmitting the heat. In a same time, fins  211 ′ that are fixed on an outer pipe  21 ′ also enhance the effect of heat dissipation for the second heat pipe  20 ′, and the gill  146  is also used to enhance the effect of heat dissipation. 
         [0036]    Accordingly, as the first and second heat pipes  20 ,  20 ′ of the present invention are provided with the first straight surfaces  22 ,  22 ′ of larger areas, which provide larger heat conduction areas; and the heat transmission is executed using the first and second thermal adhesives  30 ,  30 ′ as the heat transmission media, the heat transmission efficiency will be improved. Therefore, operating temperature on the bottom surface  42  and the outer surface  44  of the memory  40  can be almost directly transmitted to the first and second heat pipes  20 ,  20 ′, which is provided with the heat dissipation efficiency higher than that of the prior art, thereby effectively solving the problems that the heat is insufficiently dissipated from the memory  40 , and that the heat dissipation efficiency is inferior. 
         [0037]    It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
