Description

Technical Field

[0001] This utility model relates to the field of heat dissipation in energy storage devices, and in particular to a liquid cooling plate assembly and its energy storage device. Background Technology

[0002] Energy storage devices are devices or systems that can store energy and release it when needed. They are widely used in power systems, transportation, electronic equipment, and renewable energy.

[0003] A storage battery is a common energy storage device. During charging and discharging, the battery temperature rises, which affects its normal operation. Liquid cooling plates are usually used to dissipate heat from the battery. Typically, the liquid cooling plate is in contact with the surface of the battery, and copper tubes are installed on the liquid cooling plate. The coolant flowing inside the copper tubes absorbs and dissipates the heat from the battery and the liquid cooling plate. However, because the copper tubes are embedded inside the liquid cooling plate, the airflow at the copper tubes is affected, which makes it difficult for the heat to dissipate from the copper tubes and reduces the heat dissipation effect of the battery. Utility Model Content

[0004] The purpose of this invention is to provide a liquid-cooled plate assembly and its energy storage device to solve the problems mentioned in the background art.

[0014] Preferably, the heat dissipation structure further includes:

[0015] The second through slot is equidistantly arranged on the cooling plate, and the second through slot is arranged longitudinally and the second through slot is staggered with the first through slot.

[0016] A heat dissipation copper pipe is arranged in an S-shape along the inner cavity of the heat dissipation groove, and the heat dissipation copper pipe is fixedly connected to the inner wall of the heat dissipation groove.

[0017] A connecting pipe is fixedly connected to both ends of the heat dissipation copper pipe.

[0019] The heat-conducting block is slidably inserted into the inner cavity of the first through groove;

[0020] The groove is formed at the bottom of the heat-conducting block and is arranged in an arc shape. The groove is located above the heat dissipation copper pipe.

[0021] Preferably, the heat-conducting structure further includes:

[0026] The technical effects and advantages of this utility model are as follows:

[0027] This invention utilizes a combination of a cooling plate, a fixing block, a heat dissipation copper pipe, a heat-conducting block, a first thermally conductive silicone rubber, and a second thermally conductive silicone rubber. The cooling plate contacts the lower surface of the battery pack, absorbing and conducting heat. Heat is conducted through the cooling plate and fixing block, and distilled water flowing within the heat dissipation copper pipe absorbs the heat from the cooling plate and fixing block. Simultaneously, the heat dissipation groove, the first through groove, and the second through groove facilitate gas flow between the cooling plate and the heat dissipation copper pipe. Furthermore, the heat-conducting block moves within the first through groove, causing the first thermally conductive silicone rubber to adhere to the lower surface of the battery pack and the outer wall of the heat dissipation copper pipe, increasing the contact area between the battery pack and the cooling plate and heat dissipation copper pipe. The first and second thermally conductive silicone rubbers conduct heat from the battery pack, facilitating heat dissipation and improving the battery pack's heat dissipation effect.
