Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery liquid cooling technology, and in particular relates to an integrated heat dissipation immersion liquid cooling charging module. Background Technology
[0002] With the rapid development of the electric vehicle (EV) and plug-in hybrid electric vehicle (PHEV) markets, the demand for charging infrastructure is increasing daily. To shorten charging time and improve charging efficiency, cooling of charging modules has become crucial for the industry's development. The technological advancement of charging modules is gradually shifting from traditional air cooling and cold plate liquid cooling to more efficient immersion liquid cooling. However, existing immersion liquid cooling technologies still have many technical shortcomings in practical implementation.
[0003] First, when existing charging modules are liquid cooled, the coolant cannot make uniform and comprehensive contact with the circuit board inside the module, resulting in poor cooling effect and affecting the charging power of the charging pile. Secondly, when existing charging modules are cooled inside the coolant, contamination of the coolant can alter its conductivity. This means that existing charging modules cannot effectively protect the internal circuit boards, leading to damage to the charging module and affecting the normal operation of the charging station. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this invention provides an integrated heat dissipation immersion liquid-cooled charging module. Through the design of components such as a U-shaped guide plate, this invention guides the coolant entering the charging module, allowing for more comprehensive contact between the coolant and the circuit board inside the module, thereby effectively achieving more comprehensive cooling of the charging module.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated heat dissipation immersion liquid-cooled charging module, comprising a housing, one end of which is connected to an impeller fan, characterized in that a first sealing plate is detachably provided at one end of the housing, two circuit boards are provided on the side wall of the first sealing plate inside the housing, both side walls of each circuit board are slidably abutting against the inner side wall of the housing, a plurality of second through holes are provided between the two circuit boards on the side wall of the first sealing plate, a U-shaped guide plate is provided outside the two circuit boards inside the housing, a plurality of second guide plates are inclinedly provided between the two circuit boards, and a plurality of first through holes are provided between every two adjacent second guide plates on the side wall of the housing.
[0006] Optionally, multiple second guide plates on the sidewall of each circuit board are arranged uniformly from shortest to longest, and the tilt direction of each circuit board is opposite to the flow direction of the coolant between the two circuit boards.
[0007] Optionally, the upper and lower surfaces of the U-shaped guide plate are each provided with a plurality of first guide plates.
[0008] Optionally, a conductive detector is provided on the end face of the U-shaped guide plate between every two adjacent first guide plates, and a second sealing plate is slidably provided between the upper and lower ends of the U-shaped guide plate and the first sealing plate.
[0009] Optionally, a first limiting sealing strip is fixedly provided on one side of each of the second sealing plates at one end of the U-shaped guide plate, and a second limiting sealing strip is fixedly provided on one side of each of the first limiting sealing strips on the side wall of the first sealing plate.
[0010] Optionally, a plurality of first support columns are provided on both the upper and lower end faces of the housing, and a second support column is slidably disposed inside each of the first support columns.
[0011] Optionally, multiple snap-fit holes are provided on the side walls of every two adjacent first and second support columns, and a pin is slidably disposed inside one of the snap-fit holes.
[0012] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) By setting up components such as the U-shaped guide plate, the second guide plate and the first through hole, this utility model can guide the coolant entering the charging module, so that the coolant can make more comprehensive contact with the circuit board inside the charging module, thereby effectively forming a more comprehensive cooling treatment of the charging module by the coolant and improving the charging power of the charging pile. (2) By setting up components such as the first guide plate, the conductivity detector and the second sealing plate, this utility model can detect the conductivity of the coolant flowing into the charging module and in contact with the circuit board. In this way, when the coolant is contaminated, the coolant is intercepted when it enters the U-shaped guide plate, thereby reducing the damage to the circuit board and reducing the damage to the charging module when the coolant is contaminated.

Detailed Implementation
[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an integrated heat dissipation immersion liquid-cooled charging module is disclosed. Multiple charging modules are placed inside a cooling box of the charging pile, which is filled with coolant. Each charging module includes a housing 10, with an impeller fan 11 connected to one end. This impeller fan 11, similar to a propulsion impeller in a ship or submarine, guides the flow of liquid. The rotation of the impeller fan 11 draws coolant from outside the charging module into the housing 10. A first sealing plate 12 is detachably mounted on one end of the housing 10. Two circuit boards 13 are mounted on the side wall of the first sealing plate 12 inside the housing 10. A connecting filter plate 14 connects the two circuit boards 13. The system is designed to provide support between the two circuit boards 13, preventing vibrations caused by the coolant flowing through them and thus affecting their stable operation. Both sidewalls of each circuit board 13 slide against the inner sidewall of the housing 10. This sliding contact between the circuit boards 13 and the housing 10 divides the space inside the U-shaped guide plate 15 into three layers. After the coolant flows into the U-shaped guide plate 15, it first flows through the outer side of the circuit boards 13, and then between the two circuit boards 13, thus increasing the coolant's flow path length and ensuring full contact between the coolant and the upper and lower end faces of each circuit board 13, effectively improving the cooling effect of the coolant on the circuit boards 13.
[0017] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, multiple second through holes 28 are provided on the side wall of the first sealing plate 12 between the two circuit boards 13. A U-shaped guide plate 15 is provided on the outside of the two circuit boards 13 and inside the housing 10. The two circuit boards 13 and the U-shaped guide plate 15 divide the internal space of the housing 10 into multiple layers. The external coolant is drawn into the inside of the housing 10 by the impeller fan 11. Under the guidance of the U-shaped guide plate 15, the coolant flows through both sides of the U-shaped guide plate 15, then flows between the U-shaped guide plate 15 and the circuit board 13, and finally flows out through the gap between the two circuit boards 13 and the multiple second through holes 28. The arrangement of the circuit board 13 and the U-shaped guide plate 15 can lengthen the flow path of the coolant inside the housing 10, thereby increasing the flow time of the coolant inside the housing 10 and making the contact time between the coolant and the electronic components inside the housing 10 longer, thus improving the cooling effect of the charging module.
[0018] Multiple second guide plates 21 are inclinedly arranged between the two circuit boards 13. Multiple first through holes 22 are provided on the side wall of the housing 10 between every two adjacent second guide plates 21. The multiple second guide plates 21 on the side wall of each circuit board 13 are arranged evenly from short to long. The inclination direction of each circuit board 13 is opposite to the flow direction of the coolant between the two circuit boards 13. When the coolant flows out from between the two circuit boards 13, the arrangement of multiple second guide plates 21 can form a diversion and guiding effect on the coolant, thereby making the contact between the coolant and the circuit board 13 more uniform and thus strengthening the cooling effect on the circuit board 13.
[0019] Furthermore, such as Figure 2 and Figure 4 As shown, multiple first guide plates 16 are provided on both the upper and lower ends of the U-shaped guide plate 15. These multiple first guide plates 16 further divert the coolant entering the housing 10, increasing the uniform flow of the coolant within the housing 10. A conductive detector 17 is provided on the end face of the U-shaped guide plate 15 between every two adjacent first guide plates 16. Second sealing plates 20 are slidably disposed between the upper and lower ends of the U-shaped guide plate 15 and the first sealing plate 12. An electric pusher cylinder is provided on one side of each second sealing plate 20 on the outer wall of the housing 10. The output end passes through the housing 10 and is fixedly connected to one side wall of the second sealing plate 20. The setting of multiple conductivity detectors 17 can detect the conductivity of the coolant flowing into the housing 10 and towards the circuit board 13. When an abnormal conductivity of the coolant is detected, the electric push cylinder is controlled. The output end of the electric push cylinder drives the second sealing plate 20 to move between the U-shaped guide plate 15 and the first sealing plate 12, forming a blockage between the coolant entering the U-shaped guide plate 15 and the circuit board 13, preventing the coolant from flowing between the two circuit boards 13 and causing short circuit damage to the electronic components on the circuit board 13.
[0020] Furthermore, such as Figure 5 and Figure 6 As shown, a first limiting sealing strip 18 is fixedly provided on one side of each second sealing plate 20 at one end of the U-shaped guide plate 15, and a second limiting sealing strip 19 is fixedly provided on one side of each first limiting sealing strip 18 on the side wall of the first sealing plate 12. The first limiting sealing strip 18 and the second limiting sealing strip 19 are both made of flexible sealing material. The provision of the first limiting sealing strip 18 and the second limiting sealing strip 19 can increase the sealing between the second sealing plate 20 and the U-shaped guide plate 15 and between the second sealing plate 20 and the first sealing plate 12, further preventing the coolant from flowing to the outside of the circuit board 13 when the conductivity is abnormal, and improving the interception effect of the second sealing plate 20 on the coolant.
[0021] Furthermore, such as Figure 1 and Figure 5 As shown, multiple first support columns 23 are provided on both the upper and lower end faces of the housing 10. A second support column 24 is slidably arranged inside each first support column 23. When multiple charging modules are placed inside the liquid cooling box of the charging pile, the distance between the multiple housings 10 can be adjusted according to the actual working environment of the charging pile and the number of charging modules, thereby improving the flow effect of the coolant in the liquid cooling box and inside the multiple housings 10. At this time, the flow effect of the coolant can be better when multiple charging modules are stacked inside the liquid cooling box by adjusting the connection length between the second support column 24 and the first support column 23.
[0022] Furthermore, such as Figure 1 and Figure 5 As shown, each pair of adjacent first support columns 23 and second support columns 24 are provided with multiple snap-fit holes 25. Each snap-fit hole 25 has a slidable pin 26 inside. After the joint length of the first support column 23 and the second support column 24 is adjusted, the pin 26 can be snapped into the snap-fit hole 25 on the side wall of the adjacent first support column 23 and the second support column 24, thereby fixing the first support column 23 and the second support column 24 after the joint length is adjusted, and improving the stability of stacking multiple charging modules.
[0023] Finally, it should be noted that the integrated heat dissipation immersion liquid-cooled charging module of this utility model needs to protect the various mechanical structures and related motion logic in this solution. Therefore, it does not elaborate on the various sensors, detectors and driving components required for the actual operation of the various mechanical structures. However, for those skilled in the art, various control systems and electrical connection methods, including various electrical components and driving components, can be completed using conventional technical means. As long as the beneficial effects or the specific actions during the above-mentioned work can be achieved, they can be implemented. This solution does not impose too many restrictions.

Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
