Abstract
A heat-exchanging core portion includes a plurality of tubes arranged in parallel and a plurality of fin members disposed between a pair of adjacent tubes. While an electric heat emitting unit is constructed by supporting a heat emitting body including a heat emitting element inside a frame through a fin member. The electric heat emitting unit is installed into a space, which is defined in the heat-exchanging core portion, having a predetermined distance after the heat-exchanging core portion is assembled and integrally brazed while defining the space.
Claims12
A heating heat exchanger for heating air passing through said heating heat exchanger, said heating heat exchanger comprising:
- a heat-exchanging core portion having a plurality of tubes arranged in parallel and a plurality of heat exchanging fin members disposed between a pair of adjacent tubes out of said tubes;
- a heat source fluid flowing in said plurality of tubes, said heat source fluid transmitting heat to said air passing through said heating heat exchanger using said plurality of heat exchanging fin members;
- and
- an electric heat emitting unit installed in said heat-exchanging core portion, said electric heat emitting unit constructed by supporting a heat emitting body including a heat emitting element inside a frame through a heat unit fin member, said electric heat emitting unit transmitting heat to said air passing through said heating heat exchanger using said heat unit fin member.
A heat exchanger comprising:
- a first heat exchanging core portion having a first plurality of tubes arranged in parallel and a first plurality of fin members disposed between adjacent tubes of said first tubes, said first plurality of fin members transferring heat from fluid flowing in said first tubes to air passing over said first plurality of fin members;
- a second heat exchanging core portion having a second plurality of tubes arranged in parallel and a second plurality of fin members disposed between adjacent tubes of said second tubes, said second plurality of fin members transferring heat from fluid flowing in said second tubes to air passing over said second plurality of fin members;
- and
- an electric heat emitting unit disposed between said first and second heat exchanging cores, said electric heat emitting unit including a heat emitting element supported inside a frame by a heat unit fin member, said heat unit fin member transferring heat from said heat emitting element to air passing over said heat unit fin member.
