Abstract
A heat exchanger includes an extruded base member having a planar central portion and spaced-apart cooling fins extending from one side of the planar central portion. A cross-over member is located on the other side of the planar central portion and includes a plurality of spaced-apart flow channels that communicate with inlet and outlet manifolds formed in the base member or the cross-over member, or partially in both the base member and the cross-over member.
Claims20
A heat exchanger comprising:
- an elongate base member including a planar central portion having first and second side surfaces and a plurality of spaced-apart fins extending from one of said first and second side surfaces;
- a cross-over member connected to the other of said first and second side surfaces and defining spaced-apart flow channels for the flow of a heat exchange fluid over the planar central portion, the flow channels having opposed inlet and outlet end portions;
- one of the cross-over member and the base member being formed with spaced-apart, inlet and outlet manifolds communicating respectively with said inlet and outlet end portions;
- and inlet and outlet fittings communicating respectively with said inlet and outlet manifolds.
A method of forming a heat exchanger comprising the steps of:
- extruding a base member have a planar central portion and spaced-apart fins extending from one side of the planar central portion;
- forming a cross-over member having a plurality of spaced-apart transverse flow channels therein;
- forming a pair of spaced-apart flow manifolds in one of the base member and cross-over member;
- and attaching the cross-over member to the planar central portion, so that the flow manifolds and flow channels communicate with each other and the planar central portion.
A method of forming a heat exchanger comprising the steps of:
- extruding a base member having a planar central portion and spaced-apart fins extending from one side of the planar central portion, the base member also having a pair of spaced-apart inlet and outlet manifolds extending transversely from the planar central portion in the same direction as the fins;
- forming a cross-over member having a plurality of spaced-apart flow channels formed therein, the flow channels having opposed inlet and outlet end portions;
- and attaching the cross-over member to the planar central portion, so that said opposed inlet and outlet end portions communicate with the respective inlet and outlet flow manifolds.
