Power train equipment e.g. turbocharger, for motor vehicle, has bearing cooling system that is constituted by heat pipe whose end part forming evaporator is inserted in hole and positioned based on characteristics of chosen heat pipe

摘要

The equipment has a bearing cooling system that is constituted by a heat pipe (5). The heat pipe comprises an end part forming an evaporator (51), another end part forming a condensor and a central part forming an adiabatic zone. The end part forming the evaporator is inserted in a hole (14) and positioned based on characteristics of chosen heat pipe. The central part of the heat pipe is mechanically fixed to an internal combustion engine by utilizing a rod. The type of the heat pipe is chosen based on the temperature of a bearing (4).
