Description

Technical Field

[0001] This application relates to the field of heat exchanger technology, and particularly to a novel immersion heat pump type heat exchanger device. Background Technology

[0002] With the increasing prevalence of energy storage applications, the temperature uniformity and control of battery cells are becoming increasingly important. Maintaining the battery cells within a specific temperature range is beneficial to the entire system, keeping them in an optimal environment to maximize their performance and ensure stable system operation. Currently, this control method uses a liquid-cooled plate in contact with the immersion liquid, which poses a significant risk. Leakage could necessitate replacing both the immersion liquid and the coolant in the entire energy storage system. Existing methods place the liquid-cooled plate at the bottom of the battery cell, using bottom or side cooling methods in contact with the immersion liquid. However, leaks can cause the coolant to come into contact with the immersion liquid, reducing its insulation performance and potentially leading to overall insulation problems and reduced safety. Furthermore, current immersion cooling methods significantly increase overall equipment costs, hindering practical application and promotion. Summary of the Invention
