BLOWER HOUSING OF HYDROGEN RECYCLE DEVICE FOR FUEL CELL VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a blower housing of a hydrogen recycle device in which a fluid separation point on an external surface is retreated to an rear end portion of the housing body in a fuel processing system (FPS) and a cooling effect is increased and a uniform temperature difference can be obtained.

SOLUTION: The blower housing of the hydrogen recycle device is provided with cooling fins formed in an outer circumferential portion of a housing body provided inside a fuel processing system (FPS) and the cooling fins are horizontally arranged in parallel with a direction of an air flow, and a temperature difference deviation is decreased to lower a maximum temperature point. The blower housing is provided, in addition to the cooling fins arranged horizontally in parallel with the direction of the air flow, with a power source unit facing an entrance side of the FPS into which air flows and guiding wings which are arranged on both sides with a predetermined distance from the outer circumference and retreat the fluid separation point to a rear end portion of the housing body.
