ABSTRACT:
The invention provides a heat-transfer-medium heating apparatus using a PTC heater and a vehicular air-conditioning apparatus using such a heating apparatus, which have superior heat-conducting properties and ease of assembly, which can improve the heating capacity, and which can ensure sufficient electrical insulation. Included are a PTC heater having a stacked construction in which an electrode plate, an incompressible insulating layer, and a compressible heat-conducting layer are sequentially provided on each side of a PTC element so as to sandwich the PTC element; and heat-transfer-medium circulating boxes, respectively disposed in close contact with the two surfaces of the PTC heater and having circulating channels for the heat-transfer-medium formed therein. The heat transfer medium circulating inside the heat-transfer-medium circulating boxes is heated by radiant heat from the two surfaces of the PTC heater.
