Abstract
The present invention relates to a heating system for the passenger compartment of a motor vehicle which uses the laden heat of the vehicle engine to heat the passenger compartment when the engine is not running. The invention includes a heat exchanger fluidly connected into engine cooling system, a fan designed to blow air through the heat exchanger and a circulation pump which may be operated responsive to manual or automatic control to circulate coolant through the heat exchanger whereby the fan may blow air through the heat exchanger and then into the passenger compartment to heat the passenger compartment.
Claims4
In a vehicle having an engine and a cooling system therefor, said cooling system having a fluid flow system for conveying engine coolant from within the engine to and from coolant heat exchange means to cool said coolant, said engine including pump means for circulating coolant through said fluid flow system, the improvement comprising:
- (a) a further heat exchange means incorporated into said fluid flow system;
- (b) blower means for blowing air through said further heat exchange means to capture heat from said coolant and thence to blow into a passenger compartment of said vehicle to heat same;
- (c) circulation means for circulating coolant through said fluid flow system when said engine is not operating;
- and
- (d) control means for controlling operation of said blower means and said circulation mean, said control means including temperature sensing means for sensing temperature in said passenger compartment and for causing said control means to deactivate said blower means and said circulation means when said temperature is at a particular temperature.
