Description
Technical Field
[0001] The utility model belongs to the technical field of heat dissipation and cooling, and particularly relates to an insulating liquid cooling plate. Background Art
[0002] The liquid cooling plate is mainly used in the liquid cooling system of the battery pack. During the operation of the battery pack, a large amount of heat will be generated. A cooling flow channel is arranged inside the liquid cooling plate, and the coolant flowing in the cooling flow channel of the liquid cooling plate takes away the heat generated by the battery pack, avoiding potential safety hazards caused by excessive temperature of the battery pack.
[0003] However, most of the existing liquid cooling plates are directly in contact with the battery pack, and there is a certain gap between the two. Since the heat conduction ability of air is poor, these gaps will affect the heat conduction efficiency of the liquid cooling plate. Therefore, an insulating liquid cooling plate is proposed. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the problem that in the prior art, when the liquid cooling plate is in contact with the battery pack, there is a certain gap between the two, and these gaps will affect the heat conduction efficiency of the liquid cooling plate.
[0005] In order to achieve the above purpose, the utility model provides an insulating liquid cooling plate, which includes a cooling plate and a groove. The groove is embedded in the top of the cooling plate, and silicone grease is filled in the groove. The middle parts of the sides of the cooling plate are respectively connected with a liquid inlet pipe and a liquid outlet pipe. The liquid inlet pipe and the liquid outlet pipe are arranged in parallel and are located on the same side.
[0006] Preferably, the cooling plate includes a plate body, a partition plate, a first side partition plate and a second side partition plate. The side of the plate body is connected to the liquid inlet pipe and the liquid outlet pipe. The partition plate is arranged inside the plate body. The connection ends of the liquid inlet pipe and the liquid outlet pipe with the plate body are respectively located on both sides of the partition plate and are close to the partition plate. There is a gap between the end of the partition plate far from the liquid inlet pipe and the inner wall of the plate body. The first side partition plates are uniformly distributed on both sides of the partition plate, and the second side partition plates are uniformly distributed on the side surfaces of the inner wall of the plate body. The second side partition plates and the first side partition plates are arranged in an alternating manner to form a flow channel.
[0007] Preferably, a protection frame is arranged on the side surface of the cooling plate, and the connection ends of the liquid inlet pipe and the liquid outlet pipe with the cooling plate are both located inside the protection frame.
[0008] Preferably, mounting plates are arranged on both sides of the side surface of the cooling plate far from the protection frame. A mounting hole is penetrated through the center of the mounting plate, and the mounting hole is of an internal thread hole structure.
[0009] Preferably, a heat conducting plate is arranged under the cooling plate. Cavities are uniformly distributed and penetrated through the heat conducting plate, and heat dissipating plates are uniformly distributed under the heat conducting plate. The heat dissipating plates are arranged between two groups of the cavities.
[0010] Preferably, both sides of the heat dissipation plate are provided with extension ends extending towards the cooling plate, and the extension ends are attached to the end faces of the cooling plate.
[0011] The beneficial effects of the present utility model are as follows:
[0012] In the present utility model, grooves are provided on the cooling plate, and silicone grease is filled in the grooves. The cooling plate contacts the battery pack through the groove surface, and the silicone grease will automatically fill the gap between the cooling plate and the battery pack, avoiding the influence of factors such as air on heat transfer and ensuring the heat conduction efficiency; at the same time, a zigzag flow channel is provided to increase the heat exchange time of the coolant, thereby improving the heat exchange efficiency; further, the temperature of the cooling plate is absorbed through the cavity of the heat conduction plate and the heat dissipation plate for heat dissipation, thereby further improving the heat conduction efficiency.

[0019] See Figures 1 - 3, this embodiment provides an insulating liquid cooling plate, which includes a cooling plate 1 and a groove 2. The groove 2 is embedded in the top of the cooling plate 1, and silicone grease is filled in the groove 2. An inlet pipe 3 and an outlet pipe 4 are respectively connected to the middle part of the side surface of the cooling plate 1. The inlet pipe 3 and the outlet pipe 4 are arranged in parallel and on the same side surface.
[0020] Further, the cooling plate 1 includes a plate body 5, a partition plate 6, a first side partition plate 7 and a second side partition plate 8. The side surface of the plate body 5 is connected to the inlet pipe 3 and the outlet pipe 4. The partition plate 6 is arranged inside the plate body 5. The connection ends of the inlet pipe 3 and the outlet pipe 4 with the plate body 5 are respectively located on both sides of the partition plate 6 and close to the partition plate 6. The partition plate 6 divides the inside of the plate body 5 into two connected parts (an inlet part and an outlet part), such as Figure 3 the right side in the direction shown in the figure. There is a gap between the end of the partition plate 6 far from the inlet pipe 3 and the inner wall of the plate body 5 to connect the inlet part and the outlet part. The first side partition plates 7 are evenly distributed on both side surfaces of the partition plate 6, and the second side partition plates 8 are evenly distributed on the side surface of the inner wall of the plate body 5. The second side partition plates 8 and the first side partition plates 7 are arranged in an interleaved manner to form flow channels.
[0021] Further, a protection frame 9 is arranged on the side surface of the cooling plate 1. The connection ends of the inlet pipe 3 and the outlet pipe 4 with the cooling plate 1 are both located inside the protection frame 9. The protection frame 9 can prevent the connection ends of the inlet pipe 3 and the outlet pipe 4 with the cooling plate 1 from being damaged.
[0022] Further, mounting plates 10 are arranged on both sides of the side surface of the cooling plate 1 far from the protection frame 9. Mounting holes 11 penetrate through the centers of the mounting plates 10. The mounting holes 11 are of an internal thread hole structure, which is convenient for installing and fixing the cooling plate 1.
[0023] Further, a heat conducting plate 12 is arranged under the cooling plate 1. Cavities 13 are evenly distributed and penetrate through the heat conducting plate 12. Heat dissipation plates 14 are evenly distributed under the heat conducting plate. The heat dissipation plates 14 are arranged between two groups of cavities 13 to increase the contact surface with air and promote the heat dissipation of the cooling plate 1.
[0024] In one embodiment, specifically, extension ends 15 extending towards the cooling plate 1 are arranged on both sides of the heat dissipation plate 14. The extension ends 15 are attached to the end surface of the cooling plate 1, so that the extension ends 15 can also contact and absorb heat from the cooling plate 1.
[0025] In this embodiment, the working process of the insulating liquid cooling plate is as follows: The cooling plate 1 contacts with the battery pack through the groove 2 surface, and silicone grease is located between the two. Under the action of pressure, the silicone grease is evenly extruded and filled between the cooling plate 1 and the battery pack. Then, the coolant enters the plate body 5 through the liquid inlet pipe 3. Under the action of the first side partition 7 and the second side partition 8, the coolant evenly flows in the plate body 5, increasing the flow time of the coolant in the plate body 5, thereby reducing the temperature in the plate body 5 and taking away the heat on the plate body 5. The coolant is discharged through the liquid outlet pipe 4 to achieve cooling. At the same time, the heat conducting plate 12 and the heat dissipating plate 14 also assist in accelerating the cooling of the cooling plate 1.
[0026] The above content is only an example and explanation of the structure of the present utility model. Those skilled in the art of this technology can make various modifications or supplements to the described specific embodiments or use similar methods for substitution. As long as it does not deviate from the structure of the utility model or exceed the scope defined by this claim book, it shall fall within the protection scope of the present utility model.
