Title:
HEAT MEDIUM HEATING DEVICE AND VEHICLE AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/162095
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce damage to a heating body. A heat medium heating device (10) includes: a plate-shaped PTC element (41); a heat dissipation part (22) that has a recess (26) storing the PTC element (41) such that one surface of the PTC element (41) and a side wall surface (26b) face each other, and that dissipates heat of the PCT element (41) to a heat medium; and a spacer (45) disposed between the one surface and the side wall surface (26b) so as to be spaced apart from the side wall surface (26b). The spacer (45) has a facing surface facing the side wall surface (26b), and is formed such that an angle between the facing surface and the side wall surface (26b) is smaller than an angle between the one surface and the side wall surface (26b). A space between the facing surface and the side wall surface (26b) is filled with a potting agent having a higher thermal conductivity than air.
