Description

Technical Field

[0001] This utility model relates to the field of ACCDC power module technology, specifically a liquid-cooled ACCDC power module. Background Technology

[0002] A power module is a combination of power electronic devices packaged together in a specific functional configuration. Electric vehicle DC charging stations are typically located outdoors, where ground temperatures can reach as high as 50 degrees Celsius in summer. Therefore, temperature control is crucial for the core power component (AC-DC converter) of the charging station, especially in high-temperature environments. The AC-to-DC power conversion module (ACDC) used in the charging station is a high-power device. During high-power operation, the main power components inside generate significant heat. Since most electrical components have maximum operating temperatures, cooling mechanisms are necessary to cool the power conversion module.

[0003] A prior art patent application (application number 202222914291.8) discloses a liquid-cooled AC-CDC power module. This module includes a housing, a substrate, and a heating element. The housing has a mounting cavity, and its bottom has a flow channel for condensate. The housing has an inlet and an outlet communicating with the flow channel. The substrate is mounted inside the mounting cavity, and the heating element is positioned on the side of the substrate facing the flow channel, aligned with and spaced apart from it. The heating element includes one or more of a PFC coil, a resonant inductor coil, an isolation transformer coil, a PFC module, a primary-side module, and a secondary-side module. This invention discloses a charging pile, which includes the aforementioned liquid-cooled AC-CDC power module. The liquid-cooled AC-CDC power module and charging pile disclosed in this invention can solve the problems of poor heat dissipation efficiency and high noise in existing power conversion modules. However, the stability of the liquid-cooled plate during installation and fixation is low, and the liquid-cooled plate is inconvenient to disassemble and use. Utility Model Content

[0004] The purpose of this invention is to provide a liquid-cooled AC-CDC power module to solve the problems of low stability in the installation and fixing of liquid cooling plates in the prior art, and the inconvenience of disassembling and using liquid cooling plates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid-cooled AC / DC power module, including a substrate, a plurality of power components are provided on one side of the substrate, and a liquid cooling plate is slidably sleeved on the outside of the plurality of power components. A circulating liquid cooling cavity is provided inside the liquid cooling plate. A circulating water inlet and a circulating water outlet are respectively provided at both ends of the circulating liquid cooling cavity. A longitudinal support is inserted into both ends of the liquid cooling plate through a screw. A lower support is provided at the lower end of the longitudinal support. Two transverse supports are inserted into the sliding groove inside the lower support. A mounting clamp is provided at one end of the transverse support. A lead screw is rotatably provided in the middle of the sliding groove. One end of each of the two transverse supports is threaded to the lead screw.

[0006] Furthermore, the liquid cooling plate has an installation port in the middle, and the inner wall of the installation port has a heat dissipation groove.

[0007] Furthermore, the liquid cooling plate has first sliding holes inside both ends, and the two lower walls of the longitudinal support are slidably arranged with the first sliding holes.

[0008] Furthermore, the screw is rotatably mounted on the upper side of both ends of the liquid cooling plate via bearings, and the screw is threadedly connected to the middle of the longitudinal support.

[0009] Furthermore, the transverse support is a C-shaped support, and the transverse support slides through the second sliding holes at both ends of the lower support.

[0010] Furthermore, the lead screw has two opposite sets of external threads on its outer sides at both ends, and an adjusting rod is connected to the middle of the lead screw via a gear set. One end of the adjusting rod has an adjusting handle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model has a liquid cooling plate slidably sleeved on the outside of multiple power components. The liquid cooling plate has a circulating liquid cooling cavity inside. When the coolant is circulated into the circulating liquid cooling cavity, the external of multiple power components can be water-cooled and heat dissipated, resulting in good heat dissipation effect. Moreover, the liquid cooling plate covering the outside of the power components can form a certain anti-collision protection and improve the stability of multiple power components mounted on the substrate.

[0013] 2. In this utility model, longitudinal supports are inserted into both ends of the liquid cooling plate via screws. A lower support is provided at the lower end of the longitudinal support, and two transverse supports are inserted into the sliding groove inside the lower support. One end of the transverse support is provided with a mounting clamp, and a lead screw is rotatably provided in the middle of the sliding groove. Both transverse supports are threaded to the lead screw at one end, so that the two transverse supports can be moved and adjusted towards each other by rotating the lead screw. This makes it easy to clamp and fix the mounting clamp to both sides of the substrate, thereby facilitating the fixing of both ends of the liquid cooling plate. Moreover, the installation and fixing stability is high, and the disassembly and assembly are convenient and quick.

[0014] 3. In this utility model, the screw is rotatably mounted on the upper side of both ends of the liquid cooling plate via bearings. The screw is threadedly connected to the middle of the longitudinal support, so that the longitudinal support can be raised and lowered by rotating the screw, thereby adjusting the distance between the liquid cooling plate and the lower support. This allows for adjustment of the height of the liquid cooling plate installed on the outer wall of the power components, which can meet the liquid cooling requirements of liquid cooling plates of different heights.

[0021] Please see Figure 1 , Figure 2 , Figure 3In this embodiment of the present invention, a liquid-cooled AC-CDC power module includes a substrate 1.

A circulating liquid cooling cavity 21 is provided inside the liquid cooling plate 3. A circulating water inlet 19 and a circulating water outlet 20 are respectively provided at both ends of the circulating liquid cooling cavity 21. When coolant is circulated into the circulating liquid cooling cavity 21, water cooling heat dissipation treatment can be performed on the outside of the plurality of power components 2, and the heat dissipation effect is good. In addition, an installation port 4 is provided in the middle of the liquid cooling plate 3, and a heat dissipation groove 5 is provided on the inner wall of the installation port 4. The heat dissipation groove 5 can also be used to perform natural air cooling heat dissipation treatment on the outside of the plurality of power components 2, which is beneficial to improving the heat dissipation efficiency of the outside of the plurality of power components 2.

[0022] like Figure 1 and Figure 2 As shown, in order to facilitate the fixation of both ends of the liquid cooling plate 3, longitudinal brackets 6 are also inserted longitudinally at both ends of the liquid cooling plate 3 via screws 8. A lower bracket 10 is provided at the lower end of the longitudinal bracket 6, and two transverse brackets 11 are inserted transversely in the sliding groove 14 inside the lower bracket 10. One end of the transverse bracket 11 is provided with a mounting clamp 12. A lead screw 15 is rotatably provided in the middle of the sliding groove 14, and one end of each of the two transverse brackets 11 is threaded to the lead screw 15.

One end of the adjusting rod 17 is provided with an adjusting handle 18, so that the two transverse brackets 11 can be moved towards each other by rotating the lead screw 15, thereby facilitating the clamping of the mounting clamp 12 to be clamped and fixed on both sides of the substrate 1, thus facilitating the fixation of both ends of the liquid cooling plate 3. Moreover, the installation and fixing stability is high, and the disassembly and assembly are convenient and quick.

[0023] like Figure 1 and Figure 2 As shown, in order to meet the liquid cooling needs of liquid cooling plates 3 of different heights, first sliding holes 7 are provided inside both ends of the liquid cooling plate 3, and the two lower walls of the longitudinal support 6 are slidably set with the first sliding holes 7.

By rotating the screw 8, the longitudinal support 6 can be raised and lowered, thereby adjusting the distance between the liquid cooling plate 3 and the lower support 10, and thus adjusting the height of the liquid cooling plate 3 installed on the outer wall of the power component 2, so as to meet the liquid cooling needs of liquid cooling plates 3 of different heights.

[0024] like Figure 2 As shown, in order to improve the stability of the movement adjustment of the transverse support 11, a second sliding hole 13 is provided in the transverse support 11, which is a C-shaped support and slides through both ends of the lower support 10. This hole is used to guide the transverse support 11 during the lateral movement adjustment, which helps to improve the stability of the movement adjustment of the transverse support 11.

Since the liquid cooling plate 3 has a circulating liquid cooling cavity 21 inside, when the coolant is circulated into the circulating liquid cooling cavity 21, it can perform water cooling heat dissipation treatment on the outside of multiple power components 2, and the heat dissipation effect is good. Moreover, the liquid cooling plate 3 covering the outside of the power components 2 can form a certain anti-collision protection treatment, improve the safety of the power module, and at the same time help improve the stability of multiple power components 2 mounted on the substrate 1.
