Turbocompressor wheel casings for internal combustion engine of car, have evaporator portion placed between outer surfaces and inner surfaces of casing, and condenser portion arranged outside of casing on outer surfaces

摘要

The casings (3, 4) have heat pipes (37, 47) i.e. micro-capillary heat pipes, provided with an end portion i.e. evaporator portion (51) and another end portion i.e. condenser portion (52). The evaporator portion is placed between outer surfaces (39, 49) and inner surfaces (38, 48) of the casing and leveled with the inner surfaces. The condenser portion is arranged outside of the casing on the outer surfaces. One of the heat pipes is arranged such that the evaporator portion is arranged opposite to the corresponding inner surface. Independent claims are also included for the following: (1) a method for manufacturing a turbocompressor wheel casing (2) a turbocompressor wheel casing assembly.
