Description

Immersion cooling module and the control method using the same The present disclosure relates to an immersion cooling module and a control method thereof. Recently, as mobile information terminals such as mobile phones and laptops are becoming smaller and lighter, and as high capacity is required in electric and hybrid vehicles, various batteries are being developed and used as power sources. As the efficiency of secondary batteries becomes increasingly important depending on their application, problems arising from various external environments, such as heat generation or fire during charging or operation, are occurring. Accordingly, various technologies are being developed to enhance the operational efficiency of these secondary batteries and ensure their safety. Furthermore, due to the increase in carbon emissions resulting from the recent surge in electricity consumption and the issue of global warming, there is an increasing demand for more efficient device operation mechanisms, improved cooling methods, and the maximization of efficiency.

It should be understood that singular expressions include plural expressions unless otherwise specified in the context. In assigning reference numerals to the components of the drawings, identical components are assigned the same reference numeral whenever possible, even if they are shown in different drawings, and similar components are assigned similar reference numerals. Drawings may be schematic or exaggerated for the purpose of illustrating embodiments. In this document, expressions such as "have," "may have," "include," or "may include" indicate the presence of such features (e.g., numerical values, functions, operations, or components such as parts) and do not exclude the presence of additional features.

Here, the object impregnated in the cooling fluid (L1, L2) is described as a battery cell (20) as an example, but it is obvious that it can be applied to a data center or other large device or system that is not a battery cell (20), taking into account the size or specifications of the liquid immersion cooling module. As illustrated in FIG. 1, the support member (40) may be coupled inside the receiving member (10) to partition the upper and lower spaces of the receiving member (10). The coupling form of the support member (40) and the shape of the support member (40) are not limited to those illustrated, but can be appropriately arranged to form a flow of cooling fluid (L1, L2) in the two spaces.
