Abstract
The efficiency of a heat exchanger is significantly improved by connecting walls to an air flow structure, which has first grooves formed in the top surface of the structure and second grooves formed in the bottom surface of the structure, that block off alternating ends of the first and second grooves such that a first air source can only flow through the first grooves and a second air source can only flow through the second grooves.
Claims19
A heat exchanger comprising:
- an air flow structure that has a top surface, a bottom surface, a width, a length, a first edge that runs along the width, a second edge that runs along the width, a plurality of first grooves in the top surface, and a plurality of second grooves in the bottom surface, the first and second grooves extending along the length between the first and second edges;
- a first wall that contacts substantially all of the first edge of the air flow structure, the first wall having a plurality of openings that extend through the first wall such that each opening is surrounded by the first wall, no portion of the first wall extending into the plurality of first grooves, the first wall preventing a fluid in the first grooves from flowing past the first edge, the plurality of openings allowing a fluid in the second grooves to flow past the first edge;
- and
- a second wall that contacts substantially all of the second edge of the air flow structure, the second wall having a plurality of openings that extend through the second wall such that each opening in the second wall is surrounded by the second wall, no portion of the second wall extending into the plurality of first grooves, the second wall preventing a fluid in the second grooves from flowing past the second edge, the plurality of openings in the second wall allowing a fluid in the first grooves to flow past the second edge.

A method of forming a heat exchanger, the method comprising:
- forming an air flow structure that has a top surface, a bottom surface, a width, a length, a first edge that runs along the width, a second edge that runs along the width, a plurality of first grooves in the top surface, and a plurality of second grooves in the bottom surface, the first and second grooves extending along the length between the first and second edges, each groove having a substantially uniform width from the first edge to the second edge;
- and
- forming a first wall that contacts substantially all of the first edge of the air flow structure, the first wall having a plurality of openings that extend through the first wall such that each opening is surrounded by the first wall, no portion of the first wall extending into the plurality of first grooves, the first wall preventing a fluid in the first grooves from flowing past the first edge, the plurality of openings allowing a fluid in the second grooves to flow past the first edge;
- and
- connecting the first wall to the first edge of the air flow structure.
