Document Type and Number:
WIPO Patent Application WO/2021/161839
Kind Code:
A1
Abstract:
A power conversion device (1) comprising a plurality of components, including a heat-generating member (20) and a heat dissipation member (10). The power conversion device comprises a housing (11) that accommodates this plurality of components. The power conversion device comprises a snap fit (40) and a heat transfer member (50). The snap fit (40) links the heat-generating member (20) and the heat dissipation member (10). The heat transfer member (50) is positioned between the heat-generating member (20) and the heat dissipation member (10). The heat transfer member (50) is provided with a filler that has anisotropy with respect to thermal conductivity. The filler is oriented so as to exhibit high thermal conductivity in the lamination direction (LMD) between the heat-generating member (20) and the heat dissipation member (10).
