Stacked-plate heat exchanger with single plate design

摘要

A plate-type heat exchanger comprising a plurality of spaced-apart stacked plate pairs, the plate pairs each comprised of first and second plates. The first and second plates each having an elongated central, planar portion surrounded by peripheral edge portions, the peripheral edge portions of the first and second plates being sealably joined together to form a first set of fluid passages in the heat exchanger. The first and second plates are provided with boss portions at respective ends of the plates, one of the boss portions being an elongated boss portion having a first position and a second position for the location of a fluid opening. The first and second heat exchanger plates are identical in structure and can be used to form various heat exchangers using the single plate design.

主权项

1. A heat exchanger comprising:
a plurality of stacked plate pairs, each plate pair including first and second plates having elongate, central planar portions surrounded by peripheral edge portions, the peripheral edge portions of the first and second plates being sealably joined together; a first set of fluid passages defined between the elongate, central planar portions of said first and second plates; first and second boss portions formed at respective ends of each of said first and second plates and spacing apart one plate pair from an adjacent plate pair in said plurality of stacked plate pairs, the first and second boss portions defining respective inlet and outlet openings, the respective inlet and outlet openings of each of said first and second plates communicating to define respective inlet and outlet manifolds; one of said first and second boss portions being formed as an elongated boss portion thereby defining a first position and a second position for the location of a flow opening, said flow opening being one of said inlet and outlet openings in one of said inlet and outlet manifolds;wherein the first and second positions in said elongated boss portion are adjacent to each other along the length of the first and second plates, and wherein only one of said first and second positions is provided with said flow opening.
