Abstract

A heat dissipation device, particularly for a motor vehicle, said device comprising a heat pipe (10) configured for heat exchange between, on the one hand, a hot source (12) comprising an electrical component (14), and, on the other hand, a cold source (16), said device further comprising: - a first thermal interface element (50) in contact with the heat pipe (10) and intended to be in heat exchange with one of said hot or cold sources (12, 16), - a second thermal interface element (20) in contact with the heat pipe (10) and intended to be in heat exchange with the other of said hot or cold sources (12, 16), said first thermal interface element (50) being configured to be pivotally movable so as to allow angular orientation of said heat pipe (10).
