Description

Technical Field

[0001] This utility model relates to a water-cooled plate structure for an automotive domain controller, belonging to the field of automotive domain controllers. Background Technology

[0002] Automotive domain controllers are a crucial component of modern automotive electronic architecture, primarily used to manage and coordinate electronic control systems in specific domains. During operation, domain controllers are typically cooled by the flow of water through a water-cooled plate. This is a common cooling method for domain controllers. The water-cooled plate is equipped with inlet and outlet water inlets connected to water pipes. Because these inlet and outlet inlets are relatively short, their connection points are close to the circuit boards within the domain controller. If leaks occur at these connections due to seal failure, the circuit boards can easily become wet and damaged. Therefore, a water-cooled plate structure for automotive domain controllers needs to be designed to prevent uncontrolled leakage of water from the connection points. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a water-cooled plate structure for automotive domain controllers, thereby solving the problems mentioned in the background section. This invention prevents water leakage from the connection between the water-cooled plate and the water supply pipe from flowing freely.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled plate structure for an automotive domain controller, comprising a domain controller circuit board. A hollow water-cooled plate is provided on one side of the domain controller circuit board. The water-cooled plate is connected to the domain controller circuit board via multiple sets of connectors. A water inlet and a water return inlet are installed on one side of the water-cooled plate. An end cap is installed on the side of the water-cooled plate where the water inlet is installed. The water inlet and the water return inlet pass through the end cap and are fixedly connected to it. A cover is provided on the side of the end cap away from the water-cooled plate. The side of the cover facing the end cap is open. A sealing ring that contacts the end cap is installed at the open end of the cover. The cover is connected to the end cap via two sets of limiting members. A drain pipe connected to a drain pipe is installed on one side of the cover. Two through holes for inserting the water pipe are provided on the side of the cover away from the end cap. A sealing member connected to the cover is provided on the outside of the through holes.

[0005] Furthermore, the connector includes pins, and multiple pins are mounted on the side of the water-cooled plate facing the domain controller circuit board. The side of the domain controller circuit board facing the water-cooled plate has multiple holes that mate with the pins. The multiple pins pass through the multiple holes respectively. A limiting ring is provided on the side of the hole facing the water-cooled plate. The limiting ring is sleeved on the pin and connected and fixed to the pin. The side of the pin away from the water-cooled plate is threaded with a positioning screw for limiting the relative position of the pin and the domain controller circuit board.

[0006] Furthermore, an ear plate is provided on the side of the socket away from the limiting ring. A first small hole and a second small hole are provided on the upper surface of the ear plate. One end of the positioning screw passes through the first small hole and is threadedly connected to the plug. The end of the ear plate with the second small hole extends to the outside of the domain controller circuit board.

[0007] Furthermore, the limiting component includes a support lug, and both ends of the end cap are fixedly connected to the support lug. The cover is fixedly connected to the two sides adjacent to the through hole. The side of the support lug facing the support lug has a first circular hole, and the side of the support lug facing the support lug has a second circular hole aligned with the first circular hole. A connecting screw is inserted into the channel formed by the first circular hole and the second circular hole. One end of the connecting screw is threaded with a nut, and the nut is located on the side of the support lug away from the connecting lug.

[0008] Furthermore, the sealing element includes a support sleeve, and a support sleeve arranged concentrically with the perforation is provided on the outside of the perforation. One end of the support sleeve is connected and fixed to the cover, and a sealing sleeve for fitting onto the water pipe is pasted inside the support sleeve.

[0009] Furthermore, one side of the end cap is provided with a first through hole and a second through hole, the water inlet port passes through the first through hole, and the water return port passes through the second through hole.

[0010] The beneficial effects of this utility model are:

[0011] 1. Insert the multiple pins on the water-cooling plate into the multiple sockets, and then screw the positioning screws on the pins. At this time, the positioning screws and the limit rings work together to restrict the relative position of the pins and the domain controller circuit board, thus completing the assembly of the water-cooling plate and the domain controller circuit board. After the positioning screw passes through the first small hole, it is threaded into the pin. The positioning screw restricts the relative position of the ear plate, the water-cooling plate and the domain controller circuit board. After the screw passes through the second small hole and connects to the domain controller housing, the relative position of the domain controller circuit board and the domain controller housing is restricted.

[0012] 2. Pass the two water pipes through the two holes respectively, and then connect the two water pipes to the water inlet and water return interfaces respectively. Then use connecting screws and nuts to restrict the relative position of the cover and the end cap. At this time, the connection points of the water inlet and water return interfaces with the water pipes are located within the space formed by the end cap and the cover. When water leaks at the connection points of the water inlet and water return interfaces with the water pipes, the leaked water is confined within the space formed by the cover and the end cap. Subsequently, the leaked water is discharged through the channel formed by the drain pipe and the drain pipe, preventing water leaking from the connection points of the water cooling plate and the water pipes from flowing freely, thus protecting the domain controller circuit board.

[0013] 3. After the end cap and the cover are connected, the sealing ring is located between the cover and the end cap, which improves the sealing between the cover and the end cap. With the support of the sealing ring, there is a gap between the support lug and the connecting lug. At this time, part of the connecting screw is exposed. When the connecting screw and nut cannot be separated normally, the connecting screw can be cut off by using the gap between the support lug and the connecting lug. Attached Figure Description

Then, the positioning screw 14 is screwed on the plug 18. At this time, the positioning screw 14 and the limiting ring 19 work together to restrict the relative position of the plug 18 and the domain controller circuit board 1, thus completing the assembly of the water-cooling plate 15 and the domain controller circuit board 1. After the positioning screw 14 passes through the first small hole, it is threadedly connected to the plug 18, thus restricting the relative position of the ear plate 13, the water-cooling plate 15 and the domain controller circuit board 1. After the screw passes through the second small hole and is connected to the domain controller housing, the relative position of the domain controller circuit board 1 and the domain controller housing is restricted.

With respect to the end cap 17, the connection points of the water inlet 2, the water return 10 and the water supply pipe are located within the space formed by the end cap 17 and the cover 6. When water leaks at the connection points of the water inlet 2, the water return 10 and the water supply pipe, the leaked water is confined within the space formed by the cover 6 and the end cap 17. Subsequently, the leaked water is drained away through the channel formed by the drain pipe 7 and the drain pipe, preventing the water leaking from the connection points of the water cooling plate 15 and the water supply pipe from flowing freely, thus protecting the domain controller circuit board 1.
