Description

Technical Field

[0001] This utility model belongs to the field of high-voltage box technology, and in particular relates to a high-voltage box with liquid cooling. Background Technology

[0002] With the vigorous development of the new energy industry, more and more functions are being added to vehicles, resulting in a significant increase in the current demand of the entire vehicle. Consequently, the temperature of the electrical components inside the high-voltage box also rises along with the increased current. If the heat cannot be dissipated in time, the internal temperature of the high-voltage box will gradually increase. Excessive temperature will not only affect the service life of the components but also increase the failure rate of the system.

[0003] To prevent such incidents, heat dissipation is a necessary solution. Common heat dissipation methods include natural cooling, but this is inefficient. Air cooling has become a preferred alternative, but the location of the high-pressure box limits fan placement space and makes airflow control difficult, necessitating a more efficient cooling method. Therefore, this invention provides a liquid-cooled high-pressure box, which is of significant importance in addressing these issues. Utility Model Content

[0004] This invention provides a liquid-cooled high-pressure box. External coolant is introduced into the flow channel through the inlet and discharged through the outlet, achieving coolant circulation. This circulation removes surface heat from the various electrical components and conducts it outwards for heat exchange with the external environment. This effectively reduces the surface temperature of the components, preventing internal temperature rise and ensuring proper operation and lifespan. Compared to traditional air cooling, this method offers better heat dissipation and is not limited by space. The serpentine flow channel slows the coolant flow rate, extending the contact time between the coolant and the components, further improving cooling efficiency. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a liquid-cooled high-voltage box, comprising a box body, a relay, a copper busbar, a box cover, a fuse, a high-voltage capacitor, a high-voltage inductor, a Hall current sensor, and a liquid-cooling module. The box cover is installed on the top of the box body. The liquid-cooling module is fixedly connected to the inner wall of the box body and has a flow channel inside. The liquid-cooling module has a liquid inlet and a liquid outlet, which both penetrate the side wall of the box body and extend to the outside of the box body. The relay, fuse, high-voltage capacitor, high-voltage inductor, and Hall current sensor are all installed on the liquid-cooling module. The copper busbar is electrically connected to the relay, fuse, high-voltage capacitor, high-voltage inductor, and Hall current sensor respectively.

[0007] Furthermore, the flow channel is serpentine, and its two ends are connected to the inlet and outlet, respectively.

[0008] Furthermore, a sealing groove is formed on the surface of the top edge of the box body, and a sealing strip is provided in the sealing groove. Both the sealing strip and the sealing groove are rectangular, and the width of the sealing strip is equal to the width of the sealing groove.

[0009] The present invention has the following advantages over the prior art:

[0010] (1) When the liquid-cooled high-pressure box of this utility model is used, the external coolant can be introduced into the flow channel through the liquid inlet and discharged through the liquid outlet to realize the circulation of the coolant. The circulation of the coolant can remove the surface heat of each electrical component and conduct the heat outward so as to exchange heat with the outside. This can effectively reduce the surface temperature of each electrical component and prevent the internal temperature of the high-pressure box from rising and affecting the normal operation and service life of the electrical components. Compared with the traditional air cooling method, the heat dissipation effect is better and it is not limited by space.

[0011] (2) When the liquid-cooled high-pressure box of this utility model is used, the flow rate of the coolant can be slowed down through the serpentine flow channel so as to prolong the contact time between the coolant and each electrical component, thereby further improving the heat dissipation and cooling effect.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figure 1-8As shown, this utility model discloses a liquid-cooled high-voltage box, comprising a housing 1, a relay 2, a copper busbar 3, a cover 4, a fuse 5, a high-voltage capacitor 6, a high-voltage inductor 7, a Hall current sensor 8, and a liquid-cooling module 9. The cover 4 is installed on the top of the housing 1. The liquid-cooling module 9 is fixedly connected to the inner wall of the housing 1, and has a flow channel 10 inside. The liquid-cooling module 9 has an inlet 11 and an outlet 12, which both penetrate the side wall of the housing 1 and extend to the outside of the housing 1. The relay 2, fuse 5, high-voltage capacitor 6, high-voltage inductor 7, and Hall current sensor 8 are all installed on the liquid-cooling module 9. The relay 2 can control the opening and closing of the power supply, the fuse 5 can protect the equipment from being burned by abnormal current, the Hall current sensor 8 can monitor the current data in real time, and the high-voltage inductor 7 and high-voltage capacitor 6 can work together to increase the voltage. The copper busbar 3 is electrically connected to the relay 2, fuse 5, high-voltage capacitor 6, high-voltage inductor 7, and Hall current sensor 8.

[0027] The flow channel 10 is serpentine, with its two ends connected to the inlet 11 and outlet 12, respectively. External coolant can be introduced into the flow channel 10 through the inlet 11 and discharged through the outlet 12 to achieve coolant circulation. The contact surfaces of each electrical component pass through the flow channel 10, and the circulating coolant can remove the surface heat of each component and conduct the heat outward for heat exchange with the outside. This effectively reduces the surface temperature of each component, preventing the internal temperature of the high-voltage box from rising and affecting the normal operation and service life of the components.

The housing 1 is attached to the liquid cooling module 9, which is made of metal material, which can better conduct heat. The serpentine flow channel 10 can slow down the flow rate of the coolant to prolong the contact time between the coolant and each electrical component, thereby further improving the heat dissipation and cooling effect.

Both the sealing strip 14 and the sealing groove 13 are rectangular, and the width of the sealing strip 14 is equal to the width of the sealing groove 13. The sealing strip 14 is made of elastic material such as rubber and can be inserted into and adhered to the inner wall of the sealing groove 13. When the enclosure cover 4 is installed on the top of the enclosure 1, the sealing strip 14 can fill the gap between the enclosure cover 4 and the enclosure 1 to achieve a sealing effect, thereby effectively preventing external dust and moisture from entering the interior of the enclosure 1 through the gap and adhering to the surface of various electrical components.

When the various electrical components overheat due to prolonged operation, external coolant can be introduced into the flow channel 10 through the inlet 11 and discharged through the outlet 12 to achieve coolant circulation. The contact surfaces of the various electrical components pass through the flow channel 10, and the circulating flow of coolant can remove the surface heat of the various electrical components and conduct the heat outward to facilitate heat exchange with the outside. This can effectively reduce the surface temperature of the various electrical components and prevent the internal temperature of the high-voltage box from rising, which would affect the normal operation and service life of the electrical components. Compared with the traditional air cooling method, the heat dissipation effect is better and is not limited by space.
