Description

Technical Field

[0001] The invention relates to the technical field of computer hardware, in particular to a self-driven heat dissipation structure of a power module. Background Art

[0002] The computer power module is an important part of the entire computer system. The computer power module is responsible for converting and distributing electrical energy. The computer power module generally includes the CPU, power supply unit, etc. As the computer workload increases and the performance improves, the heat generated by the power module also increases. In order to ensure the normal use of the computer, the power module needs to be cooled in time;

[0003] The heat dissipation method currently used for power modules is that after the power modules generate heat, the motor in the air-cooled radiator is powered on, the rotor rotates to drive the blades to rotate, and the airflow generated by the blade rotation directly cools the CPU, etc.

[0004] For an existing heat dissipation method of power modules, the fan motor in the traditional air-cooled heat dissipation system needs to rely on the support of an external power source. Long-term use of the equipment will increase the overall energy consumption. Secondly, when installing the heat dissipation structure, holes are punched at the corresponding positions of the equipment that needs heat dissipation, and then screws are passed through these holes to fasten the heat dissipation module to the equipment. When the subsequent heat dissipation fins and fans fail, the disassembly and replacement process is very cumbersome. Thirdly, due to the small spacing between the heat dissipation fins, dust and other impurities are easily accumulated between the fins. The dust will form a heat insulation layer, which greatly reduces the heat dissipation efficiency. When the heat dissipation fins or other related components need to be inspected, repaired or replaced, it is very inconvenient to clean the dust. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a self-driven heat dissipation structure for a power module, which solves the problem that air-cooling requires an external power source to drive the motor, increases energy consumption costs, and the waste heat generated cannot be reused. Secondly, the traditional installation method requires screws to install the heat dissipation structure, which is very cumbersome in the subsequent maintenance and replacement process. Finally, dust easily accumulates on the heat dissipation fins, affecting the heat dissipation efficiency, and the small spacing between the heat dissipation fins makes it inconvenient to clean the dust.

[0015] Preferably, the contact portions between the plurality of heat dissipating fins and the heat conducting pipes are all provided with anti-wear rings.

[0016] Preferably, the temperature difference power generation sheet is electrically connected to the cooling fan.

[0017] Working principle: During the installation of the computer case, the power module is installed on the circuit board, and then the assembly board is installed at the position corresponding to the power module. The cooling fan is fixed by the buckle, and the splint is opened by rotating the shaft. The second spring is stretched, and the splint clamps the clamping block and the retracting block respectively, and then slides into the guide rail through the T-shaped slider. The heat pipe on the heat dissipation fin contacts the power module. At this time, one end of the temperature difference power generation sheet in contact with the heat pipe is the hot end, and the other end is in contact with the air. The power module generates heat when working, so that a temperature difference is formed at both ends of the temperature difference power generation sheet, thereby generating electrical energy. The generated electrical energy is connected to the motor of the cooling fan through wires. When the temperature difference power generation sheet generates enough voltage and current, the motor starts to rotate, driving the fan blades to rotate, thereby generating a forced convection cold air flow, and the heat is transferred through the heat conduction After the cooling fan is cleaned, the cooling fan is removed, the limiting bolt on the top of the slide rod is removed, the lock is opened, the blocking block is turned, and the sliding key is then slid so that the blocking block no longer blocks the limiting wheel. At this time, the third spring is compressed, the knob is turned to rotate the first rotating shaft, the winding shaft rotates with the first rotating shaft, and the cable is reeled in. The first slider on the mounting plate is pulled to the right along the slide groove, and the spacing between the cooling fins is increased through the articulated telescopic frame on the rotating block, making the cleaning process more convenient. After the processing is completed, the second spring is reset to restore the spacing between the cooling fins, and then the third spring is reset to push out the blocking block, and the blocking block is inserted into the limiting groove on the limiting wheel, so that the first rotating shaft cannot rotate.

[0018] The present invention provides a self-driven heat dissipation structure of a power module, which has the following beneficial effects:

[0019] 1. The present invention transfers the heat generated by the power module to the heat pipe through contact with the heat conduction pipe. The thermoelectric generator controls the output power of the cooling fan according to the temperature difference, and can convert the waste heat generated by the power module into electrical energy to achieve energy recovery and reuse. This not only helps to dissipate heat, but also improves the energy utilization efficiency of the entire system to a certain extent.

[0020] 2. The present invention utilizes a clamping plate to clamp a clamping block and a retracting block, thereby installing and fixing the heat dissipation device. During subsequent replacement and maintenance, the heat dissipation device only needs to be slid out through a T-shaped slider and a guide rail, thereby saving the time required for maintenance and replacement, improving maintenance efficiency, and reducing maintenance costs.

[0021] 3. The present invention rotates the knob to enable the winding shaft to reel in the cable, so that the cable can pull the first slider to move, and an articulated telescopic frame is installed on the mounting plate and the rotating block on the first slider. During the sliding process of the first slider, the articulated telescopic frame changes, and the distance between the heat dissipation fins installed by the mounting plate and the extension plate changes, which makes the cleaning of the heat dissipation fins faster and also ensures the heat dissipation effect of the heat dissipation structure.
