In general, a heat exchanger for heating a vehicle heats air by using high temperature engine coolant after cooling the engine as a heat source, and supplies the same to a vehicle interior. However, in such a heat exchanger for heating, there is a limit in that heating cannot be effectively performed at the initial stage of starting the engine.

That is, since the engine is not sufficiently heated at the start of the start-up, there is a limit to using the engine coolant that is a heat source of the heat exchanger for heating.

In addition, in the heating apparatus using the engine cooling water as a heat source, the heating performance is often insufficient due to the high performance of the vehicle engine, and such a heating problem is more serious.

In order to compensate for the insufficient heating performance, a method of mounting an auxiliary heater in a heat exchanger for heating has been attempted.

An example of such an auxiliary heater is a heating element that electrically generates heat, which has a constant temperature characteristic with increased resistance as the temperature increases, so there is little risk of fire and temperature control characteristics. It is becoming.
