Description

Technical Field

[0001] The invention belongs to the technical field of battery manufacturing, and in particular relates to a battery forming serpentine water cooling tray. Background Art

[0002] In the field of battery manufacturing, battery formation is an important link. The active substances inside the battery are activated by charging the battery to ensure the battery's charge and discharge performance. The battery formation process is a key link and requires the use of dedicated battery formation equipment for charging. Heat will be generated during the battery formation process as it is charged and discharged, and the heat will in turn affect the battery capacity. In large-scale battery formation processes, it is necessary to ensure that the temperatures of different batteries are the same so that the battery capacity is consistent. Common heat dissipation methods in the prior art include air cooling and water cooling, which ensure the uniformity of the battery temperature in the storage location by controlling the temperature of the storage location inside the formation equipment.

[0003] The "heat-gathering and temperature-controlling formation equipment" with publication number CN117638271A installs a fan at the position of the formation equipment mechanism to dissipate heat on the side of the battery, and also controls the ambient temperature of the formation workshop, that is, uses the air cooling mode. However, as the spatial positions of different battery equipment and the positions of the batteries are different, it is difficult to make the temperature uniform. The temperature of the battery close to the fan is relatively low, and the temperature far from the fan is relatively high. The utility model with publication number CN207852824U describes a water cooling mode of "a battery formation cooling water tank", which places the batteries in the same square water tank, and dissipates the heat for the formed batteries by continuously circulating cooling water, that is, using the water cooling mode.
