Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling plates, in particular to a detachable battery liquid cooling plate structure. Background Art

[0002] In the power battery system, the battery generates excess heat during operation. The heat is transferred through direct or indirect contact between the battery cell or module and the surface of the aluminum device, and is eventually carried away by the coolant passing through the internal flow channel of the device. This aluminum device is the liquid cooling plate.

[0003] At present, the existing heat dissipation method of the existing liquid cooling plate is to contact the liquid cooling plate with the surface of the power battery, and the flowing medium inside the flow channel below the liquid cooling plate takes away the heat on the surface of the power battery, so as to achieve the treatment of excess heat on the surface of the power battery. When the liquid cooling plate absorbs the heat from the surface of the power battery, the internal battery cell position heats up more seriously, and the heat treatment of the liquid cooling plate mainly relies on the medium inside the flow channel to absorb heat, and some flow channels are not in contact with the battery cell position, so that the heat treatment effect is general, which leads to excessive heat at a local position of the battery cell, posing certain safety hazards. Based on this, a detachable battery liquid cooling plate structure is proposed to solve the above problems. Utility Model Content

[0020] like Figures 1 to 3 As shown, the detachable battery liquid cooling plate structure of this embodiment includes a liquid cooling plate body 1, a supporting plate 2 and a battery. An air cushion 3 is installed above the supporting plate 2. The air cushion 3 is used to drive the liquid cooling plate body 1 to rise and fall. The liquid cooling plate body 1 is movably installed above the air cushion 3. The bottom end of the battery is in contact with the top end of the liquid cooling plate body 1. A heat conducting surface 11 is provided on the upper end surface of the liquid cooling plate body 1. The heat conducting surface 11 is used to absorb the heat from the battery surface. A liquid cooling flow channel 4 is provided at the bottom end of the liquid cooling plate body 1. The liquid cooling flow channel 4 is used to flow a heat medium. One end of the liquid cooling flow channel 4 is provided There is a fluid inlet 5, and a fluid outlet 6 is arranged at the other end of the liquid cooling channel 4. The flowing medium flows in from the fluid inlet 5 and flows out from the fluid outlet 6. The liquid cooling channel 4 and the battery cell inside the battery have the same shape and size. By setting the size and shape of the liquid cooling channel 4 to be the same as the shape of the battery cell, the flowing medium inside the liquid cooling channel 4 can absorb the heat generated when the battery cell is working, and promptly flow the heat to the external liquid cooling device along with the flowing medium, which has a good heat absorption effect on the battery cell and avoids safety hazards caused by some channels not being in contact with the battery cell position.

[0021] Specifically, a plurality of protrusions 7 are arranged on the upper end of the air cushion 3, and the interior of the protrusion 7 is connected to the air cushion 3. The air cushion 3 is inflated and deflated by external pneumatic equipment, which can drive the protrusion 7 to rise and fall, thereby realizing the lifting and lowering of the liquid cooling plate body 1 and realizing the detachable contact of the liquid cooling body 1.

[0022] Furthermore, the bump 7 is conical, and the top of the bump 7 contacts the bottom of the liquid cooling plate 1 between the liquid cooling channels 4. When the inside of the bump 7 is inflated, the bump 7 will not squeeze the liquid cooling channels 4 and will not affect the normal flow of the flowing medium in the liquid cooling channels 4.

[0023] Furthermore, guide columns 8 are installed on both sides of the lower end of the liquid-cooled plate body 1 between the liquid-cooling flow channels 4, guide holes 9 are penetrated on both sides of the upper end of the air cushion 3, and guide tubes 10 are installed on both sides of the inside of the supporting plate 2. When the air cushion 3 is inflated or deflated to drive the liquid-cooled plate body 1 to move up and down, the guide columns 8 move inside the guide holes 9 and the guide tubes 10 to guide the movement of the liquid-cooled plate body 1 and realize the vertical movement of the liquid-cooled plate body 1.

[0024] Furthermore, the shape and size of the guide column 8, the shape and size of the guide hole 9, and the shape and size of the inner diameter of the guide tube 10 match each other. When the liquid cooling plate 1 drives the guide column 8 to move, the guide column 8 will not shake left and right, and has a certain stability.

[0025] Furthermore, the fluid inlet 5 and the fluid outlet 6 are connected to an external liquid cooling device, and the flow of the flowing medium inside the liquid cooling channel 4 is achieved through the external liquid cooling device.

[0026] The method of using this embodiment is as follows: when in use, first place the battery, inflate the air cushion 3 through external pneumatic equipment, the expansion of the air cushion 3 drives the liquid cooling plate 1 to rise, and at the same time the guide column 8 moves inside the guide hole 9 and the guide tube 10, guiding the movement of the liquid cooling plate 1, so that the heat conducting surface 11 on the liquid cooling plate 1 contacts the bottom end of the battery, and then the external liquid cooling device controls the flowing medium to enter the liquid cooling channel 4. The shape of the liquid cooling channel 4 is the same as the shape of the battery cell inside the battery. The flowing medium absorbs the heat emitted by the battery cell, and then the flowing medium returns to the liquid cooling device through the liquid cooling pipe for processing, thereby absorbing the heat of the battery cell.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
