Problems solved by technology

Therefore, the cooling structure tends to be complex
Also, in order to minimize the pressure drop of the refrigerant flowing inside the radiator, as in figure 2 A structure in which the length of the flow path is reduced and the width is widened is adopted as shown in , but as in image 3 As shown in , when the width of the flow path 34 is widened, a temperature deviation may occur between the central portion and the two side portions of the flow path width
When temperature deviation occurs on the flow path, cooling of the battery cell stack is performed non-uniformly, and thus the overall cooling performance of the battery module may deteriorate

Abstract

A battery module according to an embodiment of the present disclosure comprises: a battery cell stack in which a plurality of battery cells are stacked; a module frame for accommodating the battery cell stack; and a heat sink formed below the module frame to cool the plurality of battery cells, in which the heat sink includes: a lower plate; a flow path part which is a flow path for the refrigerant; and a partition wall formed inside the flow path portion in a direction in which the flow path portion is formed, and wherein the lower plate is coupled to a bottom portion of the module frame.

Description

technical field [0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of Korean Patent Application No. 10-2020-0043243 filed with the Korean Intellectual Property Office on April 9, 2020, the disclosure of which is incorporated herein by reference in its entirety. [0003] The present disclosure relates to a battery module and a battery pack including the battery module, and more particularly, to a battery module having improved cooling performance and a battery pack including the battery module. Background technique [0004] Secondary batteries have attracted much attention as energy sources in various products such as mobile devices and electric vehicles. Secondary batteries are powerful energy resources capable of replacing the use of existing products using fossil fuels, and are attracting attention as an environmentally friendly energy source because secondary batteries do not generate by-products due to energy use. [0005] Recen...
