Abstract

A stacked plate heat exchanger (10) including a plurality of stacked plate pairs (12), each plate pair including first and second plates having elongat e central portions (34) surrounded by sealably joined edge portions with an elongate fluid passage (62) defined between the central portions. Each plate pair has spaced apart inlet (26) and outlet openings (28) in flow communication with the fluid passage, at least some of the plate pairs havin g a substantially planar air-side fin plate extending peripherally outward fro m the joined edge portions, the fin plates of the stacked plate pairs being spaced apart and substantially parallel to each other. The fluid passage may be arranged at an angle relative to air flow direction.

Claims (20)

1. A stacked plate heat exchanger with a plurality of stacked plate pairs, each plate pair including first and second plates having elongate central portions surrounded by sealably joined edge portions with an elongate fluid passage defined between the central portions; each plate pair having spaced apart inlet and outlet openings in flow communication with the fluid passage, characterized by at least some of the plate pairs having a substantially planar fin plate extending peripherally outward from the joined edge portions, the fin plates of the stacked plate pairs being spaced apart and substantially parallel to each other.
2. The stacked plate heat exchanger of claim 1 characterized in that for each of the at least some plate pairs, the planar fin plate has a first fin end and a second fin end and first and second spaced apart elongate edges extending there between, the fluid passage being located between the spaced apart edges and having a first fluid passage end located closer to the first fin end than the second fin end and a second fluid passage end located closer to the second fin end than the first fin end, the fluid passage being orientated at an angle relative to the first elongate edge of the fin plate with one of said first and second fluid passage ends being located closer to the first elongate edge than the other of said first and second fluid passage ends, the fluid passages of the plate pairs all being orientated in a common direction.
3. The heat exchanger of claim 2 characterized in that the heat exchanger is adapted to be mounted under the body of a vehicle, the first fin edge of the fin plate being an upper edge thereof.
4. The heat exchanger of anyone of claims 1 to 3 characterized in that external passages are defined between back-to-back central portions of the plates of adjacent plate pairs, and the fin plates define external passages therebetween that communicate with respective external passages between the central portions.
5. The heat exchanger of claim 4, characterized in that a fluid turbulizing structure is located in the external passages between the central portions.
6. The heat exchanger of anyone of claims 1 to 3 characterized in that for the at least some plate pairs having fin plates, the fin plate of each plate pair is formed integrally with only one of the first and second plates thereof.
7. The heat exchanger of anyone of claims 1 to 3 characterized in that for each of the at least some plate pairs having fin plates, the fin plate is formed from a first fin plate portion formed integrally with the first plate and a second fin plate potion formed integrally with the second plate, the first and second fin plates being laminated together.
8. The heat exchanger of claim 7 characterized in that cooperating locating protrusions are provided on the first and second plates for aligning the plates during assembly.

12. The heat exchanger of claim 10 or 11 characterized in that the protrusions are winglets are formed on a length of the fin plates for inducing downwash air flow onto the fin plates.
13. The heat exchanger of claim 12 characterized in that the winglets have a protruding substantially triangular shape.
14. The heat exchanger of claim 13 characterized in that at least some of the winglets are arranged in complimentary pairs.
15. The heat exchanger of anyone of claims 1 to 3 characterized in that the central portions are substantially planar and have a first plurality of obliquely orientated, parallel ribs formed thereon, the ribs of the first and second plates in each plate pair cooperating to form at least a portion of the fluid passage.
16. The heat exchanger of claim 15 characterized in that for each plate pair having a fin plate, the plate pair has elongate, parallel spaced apart first and second edges, the fluid passage being located between the spaced apart first and second edges and extending at an angle relative to the first and second edges, and the ribs on at least one of the first and second plates are orientated to be close to parallel to an air flow direction through the heat exchanger.
17. The heat exchanger of claim 1 characterized in that each of the plate pairs has a fin plate extending peripherally from the fluid passage, each fin plate having elongate, parallel spaced apart first and second edges, the fluid passage of the plate pair being longitudinally located between the spaced apart first and second edges and extending at an angle relative to the first and second edges.
18. The heat exchanger of claim 17 characterized in that for each plate pair, the edge portion of the first plate includes a laterally extending peripheral
19 locating wall surrounding an outer circumference of the edge portion of the second plate.
