Detailed ways

Please refer to FIG. 3 , which is an exploded schematic diagram of the combined structure of the CPU cooling device and the power supply of the present invention. As shown, the binding structure includes:

A cooling device 1 and a power supply 2 .

Wherein, the heat dissipation device 1 has at least a heat dissipation body 10, a fan cover 11 and a fan 12, and the fan cover 11 has a first window 111 and a second window 112; the power supply 2 does not have a fan, but has a shell The body 21 and a third window 210 and at least one fourth window 211 are opened on the casing 21 . When assembled, the fan 12 of the cooling device 1 can be inserted into the fan cover 11 and locked in the screw hole 113 of the fan cover 11 with screws (not shown). Then, the fan cover 11 is pasted on the third window 210 of the power supply 2 and locked on the housing 21 thereof. In this way, when the computer is running, the fan 12 can first draw the heat generated by the CPU (not shown) into the casing 21 of the power supply 2, and then discharge it through the fourth window 211 after combining with the heat source generated by the power supply 2 , so as to save the fan of the power supply 2 and reduce the noise when the computer is running.

Wherein, the size of the first window 111 of the cooling device 1 needs to be smaller than the third window 210 of the power supply 2 , so as to facilitate the placement and locking of the fan 12 on the casing 21 . In addition, the combination direction of the cooling device of the present invention and the power supply 2 can be changed as required. For example, when the power supply 2 is changed from the right rear to the left rear of the computer case (not shown), only Rotating the heat sink 1 from the original direction to the right by 90 degrees (compared to the direction of the back panel of the main body casing) to the left by 90 degrees can make the fan 12 stick to the third window 210 of the power supply 2 again, so that The combination of the heat dissipation device 1 and the power supply 2 of the present invention is more flexible.

Please refer to FIG. 4 , which is a schematic perspective view showing the assembly of the heat dissipation body 10 of the present invention. As shown in the figure, the cooling body 10 of the present invention further includes: at least one heat pipe 101 ; a base 102 ; and a plurality of cooling fins 103 .

Wherein, the heat pipe 101 has a metal braided mesh (not shown) inside to conduct heat: the bottom 1021 of the base 102 is hollow and at least one heat pipe 101 is passed through the hollow bottom 1021 of the base 102; In the fins 103 , each heat sink 103 has a number of holes corresponding to the number of heat pipes 101 and overlapping with each other, so that the heat pipes 101 pass through the heat sink 103 .

The operating principle of the combined structure of the CPU cooling device and the power supply of the present invention is as follows: the inside of the heat pipe 101 has a metal braided mesh and water droplets, when the base 102 conducts the heat generated by the CPU (not shown) to the heat conduction Tube 101 uses the principle that when water droplets are overheated, evaporates into water vapor and the hot air rises, the hot air will be conducted to the heat sink 103 to dissipate heat, and then the hot air will be pumped out through the sleeve fan 12, and the hot air will flow between the heat sink 103 and the heat sink. The cold air performs heat exchange, because the heat pipe 101 has a metal braided mesh to make the hot air exchange frequency faster, so that the water vapor will quickly condense into water droplets in the heat pipe 101, and the water droplets will flow down and then return to the heat pipe 101 The lower part is to exchange heat with the heat generated by the CPU again, so that the heat generated by the CPU is pumped to the power supply 2 through the fan 12, and then the heat generated by the power supply 2 and the CPU is passed through the fourth The window 211 dissipates heat to the outside of the computer case.

Wherein, the number of heat pipes 101 depends on the heat generated by the CPU. Generally speaking, one heat pipe 101 of the present invention can absorb 40 watts (w) of heat. Due to installation considerations, the heat pipe 101 will be slightly bent so that the heat pipe 101 can pass through the heat sink 103 and then be locked on the casing 21 , so the efficiency of the heat pipe 101 will be slightly reduced to about 30 watts.

The cooling fins 103 are preferably made of extruded aluminum cooling fins, but other heat dissipation materials are also available. Each cooling fin 103 has holes corresponding to the number of heat conducting pipes 101 and overlapped with each other, so that the heat conducting pipes 101 are passed through. Among the plurality of fins 103, heat exchange is performed.

Wherein, the fan cover 11 can be sleeved on the outer edge of the heat sink 103 to cover the fan 12 , and has at least one screw hole 113 for being locked on the casing 21 of the power supply 2 . And preferably, the fan cover 11 is made of metal so as to conduct heat to the casing 21 to improve heat conduction efficiency. And the fan 12 is an external blowing type, only the hot air is blown out, so the dust will not be brought into the casing 21 .

Please refer to FIG. 5 , which is a schematic diagram of the power supply of the present invention. As shown in the figure, the power supply 2 includes: a casing 21 ; a third window 210 and a fourth window 211 . Wherein the third window 210 is coupled with the fan 12, so its size needs to be slightly larger than the fan 12 so as not to block the air flow; and the size of the fourth window 211 can be determined as required, and a metal braided mesh (fig. not shown) to avoid penetration of foreign objects.

Therefore, through the implementation of the utility model, the cooling device has the advantages of good heat dissipation, quietness, easy assembly, the overall structure of the cooling device is light and heavy, so that the base of the cooling device can be more closely attached to the CPU and the sleeve fan is used to fix the fan on the On the casing, the fan vibration will not affect the cooling device. The power supply can also save a cooling fan to save the manufacturing cost of the power supply, reduce the operating noise of the computer and save power consumption.
