Abstract
A heat exchanger includes a plurality of integrally assembled heat-exchanger cores each comprising a pair of header pipes, a plurality of flat heat-transfer tubes and a plurality of fins. A heat medium flows from an inlet tube connected to one of the header pipes to an outlet tube connected to another one of the header pipes through the plurality of heat-exchanger cores communicating with one another. The heat-transfer area of the heat exchanger can be increased without increasing the diameters of its header pipes, to thereby increase the total heat-exchange ability of the heat exchanger.
Claims4
A method of generating heat exchange in an engine compartment of a vehicle between a heat medium passed through a heat exchanger and a flow of air, said method comprising:
- providing a heat exchanger including a plurality of adjacent and generally parallel heat exchanger cores each having a plurality of generally parallel heat transfer passages defining a flow path for said heat medium, at least one of said heat exchanger cores being smaller than at least one other of said heat exchanger cores;
- placing said heat exchanger into a space defined in an engine compartment of a vehicle, said space being in a flow path of the air, said placing of said heat exchanger further including positioning said passages of each of said cores to be positioned transversely across said fluid medium flow path;
- and
- causing said heat medium to flow through said heat exchanger cores and causing said air to flow along said air flow path, whereby the desired heat exchange is effected.
