The flexible PTC heating element according to the invention has one of the following constitutions. A portion of an electrodes and a PTC resistor is impregnated into a flexible substrate. A flexible substrate is made of resin foam or rubber material having a concave/convex shape formed on the surface. The flexible PTC heating element has an elongation deformation portion disposed to at least one of an electrode and a PTC resistor. A flexible substrate has adhesiveness and either a flexible substrate or a flexible cover material has an elongation control portion. Therefore, the flexible PTC heating element is highly flexible and excellent in vibration durability.

Flexible PTC heating element and method of manufacturing the heating element

A heat exchanger comprises a substantially pillar sheathed heater, a substantially cylindrical case, and a spiral spring. The sheathed heater is accommodated in the case. The spring is provided so as to be wound around an outer peripheral surface of the sheathed heater. Thus, a spiral flow path is formed among an outer peripheral surface of the sheathed heater, an inner peripheral surface of the case, and the spring. The spring functions as a flow velocity conversion mechanism, a turbulent flow generation mechanism, a flow direction conversion mechanism, and an impurity removal mechanism. A water inlet and a water outlet are respectively arranged at positions eccentric from a central axis of the case on a side surface of the case.

A heating element includes a base substrate, a pair of electrodes, a resistor capable of generating heat, a conductive resin, a terminal member, a hot melt adhesion metal, a hot melt cohesion metal, and a lead wire. The pair of electrodes is provided on the base substrate, and the resistor is formed between the pair of electrodes. The conductive resin is provided on each of the electrodes, and the terminal member is provided on the conductive resin. The adhesion metal is provided on the terminal member, and the cohesion metal forms a molten phase along with the adhesion metal. An end of the lead wire is welded to the cohesion metal. The conductive resin is provided in the vicinity of the adhesion metal so as to be affected by heat of the adhesion metal.
