Abstract
In a device for heating and circulating a fluid for vehicles wherein a fluid heating and delivering unit for heating and delivering a fluid, and a car room heat exchanger are annularly connected together to circulate the fluid in order to heat a car room, a bypass passage is installed in a fluid passage between the fluid heating and delivering unit and the car room heat exchanger, such that the bypass passage extends in a close vicinity to batteries to heat said batteries. The heated fluid for heating the car room is utilized to heat the batteries for driving the vehicle, so that the decrease of the battery temperature can be suppressed and the battery performance improved.
