Title:
VEHICLE AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/281912
Kind Code:
A1
Abstract:
The present invention provides a cabin vehicle air-conditioning device with which the heat dissipation efficiency can be increased without changing the height dimension of heat dissipation fins. The device comprises: a casing having an air inlet and an air outlet, and in which a flow channel causing the air inlet and the air outlet to communicate with each other is formed; a fan which is housed in the casing and which generates a flow of air from the air inlet, through the flow channel, and to the air outlet; a heat-generating part provided outside the casing; and a heat-dissipating part, wherein the heat-dissipating part is thermally connected to the heat-generating part and includes a base (31) having an installation surface (31a) and a plurality of plate-like fins (32) which are disposed in the flow channel, extend along the direction of air flow, and stand upright from the installation surface (31a) in a direction orthogonal to the direction of the flow, and a plurality of ridges (33) formed along the direction of the flow are provided over the upright direction of the fins (32) on the surfaces of the plurality of fins (32).
