Specifically, the upper cold plate is a stamped flat plate, and the lower cold plate is stamped into a groove. The upper and lower cold plates are welded together to form a closed space, and the groove serves as a flow channel. The coolant flows through the flow channel to achieve heat exchange.

[0004] This structure requires the design of different flow channels on the stamping plate. Due to limited space, the design and processing are difficult and the risk of failure is high. Utility Model Content

[0005] To this end, the embodiment of the utility model provides a new type of water cooling plate to solve the problems of the existing water cooling plate in the above technology, such as complex flow channel arrangement, great processing difficulty and easy failure.

[0007] A novel water cooling plate, comprising:

[0008] Fins, which are used as the spoiler structure of the water cooling plate;

[0009] A lower cold plate, wherein the middle portion of the lower cold plate is recessed toward one side to form a groove, and the shape of the groove is adapted to the shape of the fin;

[0010] An upper cold plate, the shape of which matches that of the lower cold plate, and the upper cold plate is fixedly connected to a side of the lower cold plate where the groove is provided;

[0011] A water inlet pipe and a water outlet pipe are connected to one side of the protrusion of the lower cold plate groove, and the water inlet pipe and the water outlet pipe are both connected to the inside of the groove.

[0012] Optionally, two lower cold plates are provided, and the two lower cold plates are symmetrically arranged on both sides of the upper cold plate, and the two lower cold plates are fixedly connected to the upper cold plate.

[0013] Optionally, the fins are flat fins, serrated fins or offset fins.

[0014] Optionally, a plurality of mounting holes are provided around the interconnected end surfaces of the upper cold plate and the lower cold plate, for mounting and fixing the upper cold plate and the lower cold plate on a device to be cooled.

[0015] Optionally, the fixed connection between the upper cold plate and the lower cold plate is welding, and the edges of the upper cold plate and the lower cold plate are welded to form a flow channel at the groove.

[0016] Optionally, the thickness of the upper cold plate is 0.5 mm-1 mm.

[0017] Optionally, the thickness of the fin is 0.3 mm-0.5 mm.

[0018] Optionally, the thickness of the lower cold plate is 0.5 mm-1 mm.

[0019] The utility model has at least the following beneficial effects:

[0020] The utility model provides a groove on the lower cold plate, in which the fin is placed, and the upper cold plate is fixed on one side of the groove notch of the lower cold plate, so that the groove on the lower cold plate is sealed, and the fin forms a flow channel in the groove, which increases the turbulence state, thereby improving the heat exchange efficiency.

[0032] like Figure 1-Figure 3 As shown, a new type of water cooling plate disclosed by the utility model includes:

[0033] Fin 3, fin 3 is used as a spoiler structure of the water cooling plate;

[0034] A lower cold plate 1, wherein the middle portion of the lower cold plate 1 is recessed toward one side to form a groove 11, and the shape of the groove 11 is adapted to the shape of the fin 3;

[0035] An upper cold plate 2, the shape of which matches that of the lower cold plate 1, and the upper cold plate 2 is fixedly connected to a side of the lower cold plate 1 where the groove 11 is provided;

[0036] The water inlet pipe 4 and the water outlet pipe 5 are connected to one side of the protrusion of the groove 11 of the lower cold plate 1 , and the water inlet pipe 4 and the water outlet pipe 5 are both connected to the inside of the groove 11 .

[0037] The novel water-cooled plate comprises an upper cold plate 2, a lower cold plate 1, fins 3, a water inlet pipe 4 and a water outlet pipe 5. The fins 3 are between the upper cold plate 2 and the lower cold plate 1, serving as a circulation channel for the coolant or cooling medium, and the water inlet pipe 4 and the water outlet pipe 5 are arranged on the lower cold plate 1, and connected with external pipes to form a circulation channel.

[0038] The lower cold plate 1 is made of a stamped thin plate with a thickness of 0.5mm-1mm; a groove 11 is provided on the lower cold plate 1, and the structure of the groove 11 can be determined according to the size of the fin 3 and the pressure requirement of the flow channel, and a hole or a boss connected to the inlet and outlet water pipes 5 is provided on the groove 11; a bolt mounting hole is provided on the lower cold plate 1 to facilitate connection with the battery frame or the motor electronic control bracket;

[0039] The upper cold plate 2 is a flat plate with a thickness ranging from 0.5 mm to 1 mm. The upper cold plate 2 is provided with mounting holes for being mounted and fixed together with the lower cold plate 1 after being welded.

[0040] like Figure 4 As shown, further, two lower cold plates 1 may be provided, and the two lower cold plates 1 are symmetrically arranged on both sides of the upper cold plate 2 , and the two lower cold plates 1 are fixedly connected to the upper cold plate 2 .

[0041] The above-mentioned lower cold plate 1 and fin 3 are both provided with two, the two lower cold plates 1 are respectively fixed on both sides of the upper cold plate 2, the two lower cold plates 1 share one upper cold plate 2, the fin 3 is correspondingly arranged in the groove 11 of the lower cold plate 1, and the structures on both sides of the upper cold plate 2 are the same, forming a double-layer water-cooling structure of lower cold plate 1-fin 3-upper cold plate 2-fin 3-lower cold plate 1;

[0042] According to the heat dissipation requirements, the heat exchange requirements increase, and the above-mentioned double-layer water cooling plate setting can be adopted.

[0043] Furthermore, the fins 3 are flat fins 3 , serrated fins 3 or offset fins 3 .

[0044] The fins 3 mentioned above can be selected with different structures according to the heat dissipation requirements, and the thickness of the fins 3 is 0.3mm-0.5mm.

[0045] The flat fins 3 are relatively simple to manufacture, with low cost, and the straight fins 3 are easier to clean and maintain. The flat fins 3 can provide a uniform heat conduction path, which helps the water-cooling liquid to evenly absorb heat;

[0046] The serrated fins 3 can increase the contact surface area with the water-cooling liquid, thereby improving the heat exchange efficiency, and at the same time can reduce the resistance of the water-cooling liquid flow and improve the heat dissipation performance;

[0047] The offset fins 3 can reduce the short circuit phenomenon of the water-cooling liquid inside, ensure that the water-cooling liquid flows through all the fins 3, and improve the heat exchange efficiency.

[0048] A plurality of mounting holes are provided around the interconnected end surfaces of the upper cold plate 2 and the lower cold plate 1 for mounting and fixing the upper cold plate 2 and the lower cold plate 1 on the equipment to be cooled.

[0049] The above-mentioned installation holes can be used to install bolt assemblies, and the water cooling plate can be fixed to devices that require heat dissipation, such as battery frames or motor and electronic control brackets, through the bolt assemblies.

[0050] The upper cold plate 2 and the lower cold plate 1 are fixedly connected by welding. The upper cold plate 2 and the lower cold plate 1 are welded at their edges to form a flow channel at the groove 11 .

[0051] The novel water-cooling plate of the utility model can increase the heat exchange area and improve the heat exchange efficiency by adding fins 3. The fins 3 can be designed into different structural forms, which are determined according to the requirements of heat exchange performance.

[0052] Moreover, only a large groove 11 is required on the lower cold plate 1, and a large number of flow channels with complex structures are not required, which greatly reduces the difficulty of design, reduces the difficulty of stamping, and reduces the risk of welding leakage.

[0053] The above specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0054] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
