Description

Technical Field

[0001] This utility model relates to the field of power supply equipment technology, specifically a heat dissipation device for power equipment. Background Technology

[0002] During the operation of a power system, the internal components of electrical equipment generate a large amount of heat due to the thermal effect of electric current. Therefore, it is necessary to configure corresponding heat dissipation devices for electrical equipment to improve its heat dissipation capacity. Currently, most existing heat dissipation devices for electrical equipment on the market adopt a one-to-one design, meaning that the heat dissipation capacity of the heat dissipation device must be matched with a specific model and power of electrical equipment. This one-to-one heat dissipation device has the problems of poor versatility and insufficient adaptability. When electrical equipment in the same scenario is updated, the original heat dissipation device, because its heat dissipation capacity is fixed, cannot adapt to the power requirements of the new equipment, and the entire device must be replaced, resulting in a significant increase in equipment maintenance costs. Utility Model Content

[0003] The purpose of this invention is to provide a heat dissipation device for power equipment, which improves the adaptability of the heat dissipation device through a configurable air distribution component.

[0004] This utility model is achieved through the following technical solution: a heat dissipation device for power equipment, comprising: The box body has multiple configuration holes on its side wall, and an inlet pipe and a return pipe are respectively installed on both sides of the configuration holes; At least one air distribution component is installed in the corresponding configuration hole; a sealing plate is installed in the configuration hole where no air distribution component is installed; The air distribution assembly includes a base plate installed in the configuration hole, and a housing is provided on the outside of the base plate; a heat exchange tube is installed on the base plate at a position opposite to the configuration hole, and the two ends of the heat exchange tube are connected to the liquid inlet pipe and the liquid return pipe; an air intake fan is installed on the side of the housing away from the configuration hole.

[0005] Preferably, the configuration hole is a rectangular hole, and multiple configuration holes are evenly distributed vertically along the side wall; the liquid inlet pipe and the liquid return pipe are placed on both sides of the configuration hole and are embedded in the side wall.

[0006] Preferably, a cold source for providing cooling medium is fixed on one side of the housing, and the liquid inlet pipe and liquid return pipe are connected to the inlet and outlet of the cold source respectively.

[0007] Preferably, an external filter screen is fixed to the outside of the air inlet fan.

[0008] Preferably, the heat exchange tubes are arranged in a roundabout manner, and metal mesh is attached and fixed to both sides of the heat exchange tubes.

[0009] Preferably, an inner filter screen is fixed inside the configuration hole.

[0010] Preferably, the heat exchange tube and the liquid inlet tube are connected by a quick connector; the quick connector includes a plug tube that is fixedly connected to the liquid inlet tube and a sleeve that passes through the substrate; the plug tube and the sleeve are connected, and the sleeve is fixedly connected to one end of the heat exchange tube.

[0011] Preferably, the inner end of the sleeve is fitted with the insertion tube through a stop, and the outer end of the sleeve is fitted with a fastening bolt; the inner end of the fastening bolt is located in the insertion tube and is threadedly connected to the insertion tube, and the cap of the outer end of the fastening bolt is pressed against the outer end of the sleeve; the inner end of the fastening bolt has a flow channel connecting the insertion tube and the liquid inlet tube.

[0012] Preferably, the heat exchange tube and the return pipe are also connected by a quick connector.

[0013] Preferably, the top of the enclosure is provided with a heat dissipation window, and the side is provided with a door.

[0014] The beneficial effects of this utility model are: based on the actual power of the power equipment, the number of air distribution components to be installed can be adapted to the power of the cold source through multiple sets of standardized configuration holes on the side wall of the enclosure, so as to achieve a precise match between the power of the power equipment and the heat dissipation capacity. There is no need to design heat dissipation devices separately for equipment with different power, which greatly improves the versatility of the enclosure and heat dissipation devices and adapts to power equipment with different power levels. The air distribution assembly employs a combination structure of meandering heat exchange tubes and double-layer metal mesh. The heat exchange tubes and metal mesh are tightly fitted together, which increases the contact area between the cooling medium and the air. On the other hand, the metal mesh can quickly conduct the cooling capacity of the heat exchange tubes, forming an efficient heat exchange path of pipe-mesh-air, resulting in faster cooling speed and better temperature uniformity. The air distribution assembly and pipelines are quickly connected via quick-connect couplings. Sealing is achieved simply by tightening the bolts. The double sealing structure of stop fit and bolt tightening effectively prevents cooling medium leakage and ensures the reliability of the heat dissipation system. Attached Figure Description

The heat exchange tubes 33 are tightly fitted to the metal mesh 35 to improve heat exchange efficiency. Both ends of the heat exchange tubes 33 are pre-embedded in the base plate 34. During installation, both ends of the heat exchange tubes 33 are connected to the inlet pipe 21 and the return pipe 22 respectively, forming a complete medium flow loop. The middle of the housing 31 protrudes outward, and mounting holes are opened at the protrusion for installing the air intake fan 32. An external filter screen 321 is installed on the outside of the air intake fan 32 to block impurities in the outside air. An internal filter screen 121 is installed on the inner side of the configuration hole 12 for further filtering of air impurities and water vapor. Example 2:
