Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, and in particular to a modular heat dissipation device for a power distribution load. Background Art

[0002] The power distribution load is a device used to simulate actual loads and is often used in the testing and debugging of power systems. It can simulate various load conditions to test power generation equipment, transformers, cables and other power distribution equipment to ensure that they can operate normally in actual applications. The load consumes a lot of electrical energy during the test and converts it into heat energy, so an effective heat dissipation system is required to prevent the equipment from overheating. The modular design allows heat dissipation modules to be added or reduced according to the power and heat dissipation requirements of the load. This flexibility allows the heat dissipation system to be adjusted according to actual needs to ensure that the heat dissipation efficiency matches the load.

[0003] Traditional modular heat dissipation devices for power distribution loads are usually based on the principle of liquid cooling to dissipate the heat generated by the equipment during operation. The circulating coolant is used to absorb the heat, which flows through the radiator and releases the heat to the outside air through the heat sink. A water pump and an external cooling tower may be included to enhance the heat dissipation capacity.

[0004] The above-mentioned traditional modular heat dissipation device system for power distribution loads is relatively complex, including water pumps, pipes, coolant, etc., which are difficult to install and maintain. The liquid cooling system has the risk of coolant leakage, which may damage the equipment or cause environmental pollution. The initial investment of the liquid cooling system is usually higher than that of the air cooling system. Utility Model Content

[0027] Specifically, the housing 1 is the frame structure of the entire device, providing protection and support. The first heat dissipation hole 2 and the second heat dissipation hole 3 are used for air circulation to help dissipate heat. The motor 6 is a power source, which drives the first fan blade 9 through a fixedly connected connecting plate 7 and a connector 8. The first fan blade 9 is an active heat dissipation component. When the motor 6 rotates, the first fan blade 9 also rotates to generate wind flow, thereby taking away the heat inside the housing 1. The square plate 11 is rotatably connected to the outer wall of the first fan blade 9 in order to increase the structural strength of the fan blade or adjust the direction of the wind flow. It is connected to the fixed block 5 through the U-shaped plate 10, and the two ends are connected to the rotating block 12. The purpose of this design is to ensure the stability of the entire system when the fan blade rotates.

[0028] Reference Figure 1 - Figure 3 The opening assembly includes a door 13 , an outer wall of the door 13 is arranged on the upper surface of the shell 1 , and a handle 15 is fixedly connected to the outer wall of the door 13 .

[0029] Specifically, the opening assembly of the outer wall of the box body 16 may be for the purpose of facilitating maintenance and overhaul, so that the housing 1 can be opened quickly without complete disassembly.

[0030] Reference Figure 4 - Figure 6 The outer wall of the box door 13 is rotatably connected to the box body 16, the interior of the box body 16 is slidably connected to the iron shell 17, the outer wall of the iron shell 17 is fixedly connected to the sliding block 18, the outer wall of the sliding block 18 is slidably connected to the interior of the box body 16, the interior of the iron shell 17 is fixedly connected to the cooling fan 19, the interior of the iron shell 17 is fixedly connected to the heat absorbing block 22, the interior of the heat absorbing block 22 is fixedly connected to the heat conducting pipe 21, the outer wall of the heat conducting pipe 21 is fixedly connected to the heat sink 20, the outer wall of the heat sink 20 is arranged in the interior of the iron shell 17, the upper end of the heat conducting pipe 21 is arranged below the cooling fan 19, the interior of the box body 16 is fixedly connected to the heat pipe 14, and the interior of the heat pipe 14 is rotatably connected to the second fan blade 23.

[0031] Specifically, the iron shell 17 is a protective structure for the internal components, and the sliding block 18 enables the iron shell 17 to slide along the inside of the box 16, which is used to adjust the position of the cooling fan 19 or facilitate replacement. The cooling fan 19 is an active cooling component used to generate wind flow and accelerate heat dissipation. The heat absorption block 22 is located below the cooling fan 19, and its function is to absorb heat and prepare to transfer it to the heat pipe 21. The function of the heat pipe 21 is to quickly transfer the heat absorbed by the heat absorption block 22 to the heat sink 20. The heat sink 20 increases the heat dissipation through its larger surface area, thereby improving the heat dissipation efficiency. The heat pipe 14 is fixed inside the box 16, and the second fan blade 23 inside it can rotate, probably to enhance the wind flow and improve the heat dissipation effect.

[0032] Working principle: When a modular heat dissipation device for a power distribution load is needed, first, the motor 6 drives the connecting plate 7 to rotate and drives the connector 8 to rotate, and the connector 8 drives the first fan blade 9 to rotate 360 ​​degrees through the motor 6. The square plate 11 can rotate above the U-shaped plate 10 so that the connector 8 and the first fan blade 9 can rotate 360 ​​degrees and can swing up and down slightly, thereby achieving the effect of heat dissipation for the electronic components inside the housing 1. The hooks and sliding blocks 18 on the surface of the iron shell 17 enable the iron shell 17 to slide inside the box 16. Through the hooks and sliding blocks 18 on the surface of the iron shell 17, each heat dissipation module can be replaced or upgraded separately, which improves the flexibility of maintenance and upgrading. The heat generated by the electronic components is absorbed by the heat absorption block 22, and the heat absorbed by the heat absorption block 22 is dissipated to the surface of the heat sink 20 through the heat pipe 21. The heat sink 20 is in contact with the air so that the heat can be dissipated to a certain extent. The heat dissipation fan 19 can better dissipate the heat on the surface of the heat sink 20. The heat dissipated from the inside of the box 16 can be discharged from the inside of the box 16 through the heat pipe 14 and the second fan blade 23, thereby achieving the heat dissipation effect.
