Abstract
A plate and fin type heat exchanger is disclosed which can be made in any convenient size with minimum tooling required. The heat exchanger is made from a plurality of stacked plate pairs having raised peripheral edge portions to define flow channels inside the plate pairs. The plates of the plate pairs are formed with offset, diverging end flanges that space the plate pairs apart. A U-shaped channel envelops the plate end flanges to form part of a manifold at each end of the plate pairs. End caps or plates close the open ends of the U-shaped channels to complete the manifolds, and inlet and outlet openings are formed in the manifolds as desired to complete the heat exchanger.
Claims (20)
1. A heat exchanger comprising:
a plurality of stacked plate pairs formed of mating plates having central planar portions and raised peripheral edge portions, said edge portions being joined together in mating plates to define a flow channel between the plates;
the plates having offset end flanges, the respective flanges at each end of each plate pair diverging, the flanges having lateral edge portions extending from root areas located at the joined peripheral edge portions, the end flanges also having transverse distal edge portions joined together in back-to-back stacked plate pairs to space the plate pairs apart and form transverse flow passages between the plate pairs; opposed U-shaped channels enclosing the respective end flanges of the plate pairs, the channels having rear walls spaced from the plate end flanges and side walls joined to the flange lateral edge portions and covering said root areas, the U-shaped channels having open ends; end plates closing the U-shaped channel open ends to form manifolds; and the manifolds defining inlet and outlet openings therein for the flow of fluid through the plate pairs.
a plurality of stacked plate pairs formed of mating plates having central planar portions and raised peripheral edge portions, said edge portions being joined together in mating plates to define a flow channel between the plates;
the plates having offset end flanges, the respective flanges at each end of each plate pair diverging, the flanges having lateral edge portions extending from root areas located at the joined peripheral edge portions, the end flanges also having transverse distal edge portions joined together in back-to-back stacked plate pairs to space the plate pairs apart and form transverse flow passages between the plate pairs; opposed U-shaped channels enclosing the respective end flanges of the plate pairs, the channels having rear walls spaced from the plate end flanges and side walls joined to the flange lateral edge portions and covering said root areas, the U-shaped channels having open ends; end plates closing the U-shaped channel open ends to form manifolds; and the manifolds defining inlet and outlet openings therein for the flow of fluid through the plate pairs.
2. A heat exchanger as claimed in claim 1 wherein the plate end flange transverse distal edge portions are in the form of flange extensions extending generally parallel to the plate central planar portions.
3. A heat exchanger as claimed in claim 1 wherein the plate raised peripheral edge portions are formed with fingers spaced from said flange lateral edge portions to define slots to accommodate the U-shaped channel side walls.
4. A heat exchanger as claimed in claim 3 wherein said slots are tapered to urge the U-shaped channel side walls against the flange lateral edge portions.
5. A heat exchanger as claimed in claim 1 wherein the plate raised peripheral edge portions are formed with transverse notches located between but adjacent to said root areas, and wherein the U-shaped channel side walls have inwardly disposed peripheral flanges adapted to snap into said notches.
6. A heat exchanger as claimed in claim 5 wherein said notches have a depth greater than the width of the U-shaped channel side wall peripheral flanges.
7. A heat exchanger as claimed in claim 2 and further comprising a baffle attached to one of said flange extensions and extending between the U-shaped channel rear and side walls to divide the manifold into a plurality of compartments.
8. A heat exchanger as claimed in claim 7 wherein said baffle has a resilient wall portion.
9. A heat exchanger as claimed in claim 2, 3, or 5 and further comprising heat transfer fins located between the plate pairs and in contact with the plate planar central portions.
10. A heat exchanger as claimed in claim 2 wherein said transverse distal edge portions are formed with notches therein to adjust the flow distribution through the U-shaped channels.
11. A heat exchanger as claimed in claim 7 or 8 wherein the manifold includes additional inlet and outlet openings, at least one of said inlet and outlet openings being associated with each of said compartments.
12. A heat exchanger as claimed in claim 1 wherein the U-shaped channel side walls are formed with ribs to engage and locate the end plates.
13. A heat exchanger as claimed in claim 2 wherein the U-shaped channel side walls are formed with ribs to engage and locate the plate end flange extensions.
14. A heat exchanger as claimed in claim 12 or 13 wherein said ribs are located in closely spaced-apart pairs to define locating slots therebetween.
15. A heat exchanger as claimed in claim 2 wherein one of said flange extensions extends fully between the U-shaped channel rear and side walls to form a baffle dividing the manifold into a plurality of compartments.
16. A method of making a heat exchanger comprising the steps of:
providing an elongate strip of plate material having a planar central portion and raised peripheral edge portions; cutting the plate material into predetermined lengths; forming the plate lengths with offset end flanges extending in a direction away from the raised peripheral edge portions; arranging the plate lengths into plate pairs with the offset end flanges diverging and the plate peripheral edge portions in contact; stacking said plate pairs so that the end flanges engage to space the plate pairs apart; providing U-shaped channels enclosing the plate offset end flanges, the channels having open ends; closing the open ends of the channels to form manifolds; forming inlet and outlet openings in the manifolds; and joining the plates and manifolds together to form a sealed heat exchanger.
