Abstract

A heat exchanger includes a leeward condenser core including a plurality of first fluid conduits having a first flow circuit formed therethrough to receive a heat exchanging medium, a windward condenser core positioned adjacent and in fluid communication with the leeward condenser core, the windward condenser core including a plurality of second fluid conduits having a second flow circuit formed therethrough to receive the heat exchanging medium, a header plate securing the windward condenser core to the leeward condenser core, the header plate forming at least a portion of a first tank in fluid communication with each of the first fluid conduits and a second tank in fluid communication with each of the second fluid conduits, a first cap disposed on the header plate to form the first tank, and a second cap disposed on the header plate to form the second tank.

Claims

1. A heat exchanger comprising:

a leeward condenser core including a plurality of first fluid conduits having a first flow circuit formed therethrough to receive a heat exchanging medium;

a windward condenser core positioned adjacent and in fluid communication with the leeward condenser core, the windward condenser core including a plurality of second fluid conduits having a second flow circuit formed therethrough to receive the heat exchanging medium;

a header plate securing the windward condenser core to the leeward condenser core, the header plate forming at least a portion of a first tank in fluid communication with each of the first fluid conduits and a second tank in fluid communication with each of the second fluid conduits;

a first cap disposed on the header plate to form the first tank; and

a second cap disposed on the header plate to form the second tank.

2. The heat exchanger according to claim 1, wherein the first cap forms a fluid-tight seal with a first portion of the header plate connecting to and in fluid communication with each of the first fluid conduits, and the second cap forms a fluid-tight seal with a second portion of the header plate connecting to and in fluid communication with each of the second fluid conduits.

3. The heat exchanger according to claim 1, further comprising a plurality of fins, each of the fins interposed between adjacent ones of each of the first fluid conduits and the second fluid conduits.

4. The heat exchanger according to claim 3, wherein at least one of the fins extends between a pair of adjacent ones of the first fluid conduits and a pair of adjacent ones of the second fluid conduits.

5. The heat exchanger according to claim 1, wherein the first fluid conduits are spaced from the second fluid conduits by a gap ranging from about 0.0 to 14.0 millimeters.

6. The heat exchanger according to claim 1, wherein the first flow circuit includes at most three circuit passes through the leeward condenser.

7. The heat exchanger according to claim 1, wherein the second flow circuit is downstream of the first flow circuit.

8. A heat exchanger comprising:

a leeward condenser core including a plurality of first fluid conduits having a first flow circuit formed therethrough to receive a heat exchanging medium, each of the first fluid conduits having a first width;

a windward condenser core positioned adjacent the leeward condenser core, the windward condenser core including a plurality of second fluid conduits having a second flow circuit formed therethrough to receive the heat exchanging medium, each of the second fluid conduits having a second width; and

a plurality of fins disposed adjacent each of the first fluid conduits and the second fluid conduits, each of the fins interposed between adjacent ones of each of the first fluid conduits and the second fluid conduits and having a fin width greater than the first width and the second width combined.

9.
