Device for cooling battery cells of e.g. traction battery of electric vehicle, has heat pipe utilized as evaporator or part of evaporator of cooling circuit and connected with cooling circuit and/or separable from cooling circuit

摘要

The device (1) has a heat pipe (8) utilized as an evaporator (4) or part of the evaporator of a cooling circuit. The heat pipe is connected with the cooling circuit and/or separable from the cooling circuit. Pressure of working medium (7) of the heat pipe is adjustable by a compressor (5). Heat energy of a battery cell (2) is received by a part of a heat absorbing surface (81) of the heat pipe and transferred to a cooling agent and/or a cooling section by a part of a heat emission surface (82) of the heat pipe, where the heat emission surface is arranged outside a motor vehicle. An independent claim is also included for a method for cooling a heat pipe.
