Description

Technical Field

[0001] The utility model relates to the technical field of battery cooling, in particular to a cooling device for energy storage. Background Art

[0002] New energy vehicles are developing rapidly, and improving charging speed is the general trend. With the rapid development of the new energy vehicle industry, the cruising range of electric vehicles is constantly increasing, so the application scope of charging piles has increased significantly. With the improvement of battery technology, battery density is getting larger and larger, the charging rate of vehicles is getting higher and higher, and then the cruising range of vehicles is getting longer and longer. As a result, charging technology is getting higher and higher, which means that the power of chargers is getting larger and larger.

[0003] The charging stack integrates the batteries, receives the charging demand value from the electric vehicle through the platform, calculates the number of charging modules required, notifies the matrix controller to distribute power, and dynamically adjusts the actual output voltage according to the needs of the electric vehicle. There are multiple batteries in the charging stack, so there are also many lines connected to the batteries.

[0004] It is well known that the charging stack will generate heat during use. For this reason, each battery end in the existing charging stack is equipped with a fan, and the fan is used to dissipate heat from the battery. The heat dissipation effect is poor, and the back terminal of the battery is seriously heated. If it is in a heated state for a long time, the terminal head will be damaged, affecting the normal use of the battery. In order to solve the above technical problems, relevant patents have been proposed in the prior art, such as the application number 202222493216.9, the authorization publication number CN217655961.U, and the invention name is a Chinese utility model patent for a liquid cooling structure of a charging stack. The above patent discloses a liquid cooling structure of a charging stack, including a control box and a battery, and also includes a heat sink. Protective plates are installed on both sides of the wiring port, and a cavity is connected between the protective plate and the heat sink. An elastic heat conductive sheet is provided on the inner wall of the side where the two protective plates are close to each other; a flow control component includes an adjustment plate rotatably installed in the first connecting pipe, and the rotating control plate drives the adjustment plate to control the water inlet cross-sectional area of ​​the first connecting pipe.

[0005] The above patent sets a cavity, uses coolant to cool the battery, and sets two protective plates at the connection port of the heat sink, and uses the protective plates to cool the external connection of the power source, further improving the cooling effect. It is well known that when the battery is used continuously for a short period of time, it will generate heat. In the prior art such as the above patent, the heat can only be dissipated by the heat conductive block, and the battery body cannot be dissipated when in contact with the heat sink, so the heat dissipation efficiency is insufficient and there are certain limitations.
