Abstract
The utility model discloses a heat sink on a power battery pack, which comprises monomer batteries, wherein the monomer batteries are connected in a series-parallel connection mode, a battery clearance hole is left between abreast adjacent cylindrical batteries, an evaporation end of a heat pipe is inserted into the battery clearance hole, and the other end of the heat pipe is a condensing end connected with cooling fins. The battery clearance hole is a through hole, and the cooling fins located on both sides of the condensing end of the heat pipe are connected and fixed. The phase transition temperature of a working medium in the heat pipe is 20-40 DEG C. The heat sink disclosed by the utility model has the following effects that the heat sink carries out heat dissipation on the power battery pack through the heat pipe and the cooling fins; and the phase transition temperature of the working medium in the heat pipe is 20-40 DEG C, so that the evaporation end of the heat pipe greatly absorbs heat gathered among the monomer batteries in the battery pack, and the condensing end of the heat pipe evaporates the heat to the external space of the battery pack through the cooling fins, thereby achieving the purpose of heat dissipation.
