Embodiment Construction
[0055] figure 1 Shown is a heat transfer element (10) of a device (100) for cooling at least one battery cell (201) of a battery module (200). The heat transfer element (10) is designed flat. Furthermore, the heat transfer element (10) is configured plate-shaped and has a longitudinal direction (15) and a thickness direction (14). The heat transfer element (10) is configured to be compressible in the thickness direction (14). The heat transfer element (10) can thus be squeezed together in the thickness direction (14).
[0056] The heat transfer element ( 10 ) has two flat sides ( 18 ), which can be arranged in such a way that they each rest on the flat sides of the battery cells ( 201 ) of the battery module ( 200 ). Thereby, the volume expansion of the battery cell (201) due to the compression of the heat transfer element (10) in the thickness direction (14) can be balanced.
[0057] The heat transfer element (10) has two longitudinal ends (16), wherein in the corner regi...
