Embodiment Construction

[0025] first reference figure 1 , numeral 10 represents a preferred embodiment of the heat exchanger according to the present invention. Heat exchanger 10 is a radiator for cooling the coolant on an internal combustion engine, such as is commonly found in vehicles. The heat exchanger 10 has a filler cap 12 mounted on a suitable connection 14 having an overflow or relief outlet 16 thereon. The heat exchanger 10 has a core 18 formed of a plurality of spaced pairs of plates 20 with fins 22 disposed therebetween. The fins 22 are conventional corrugated fins used in heat exchangers with transverse corrugations or holes 24 in the fins to improve heat transfer (see Figures 3 and 8). Any form of heat sink may be used in the present invention, or no heat sink may be used if desired.

[0026] The heat exchanger 10 has a pair of headers 26 , 28 at each end of the pair of plates 20 . Inlet and outlet couplings or fittings 30, 32 are mounted on the headers 26, 28 to allow cooling fluid...

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 (20) having raised peripheral edge portions (50, 52) to define flow channels (54) inside the plate pairs. The plates (44, 46) of the plate pairs are formed with offset, diverging end flanges (56, 58) that space the plate pairs apart. A U-shaped channel (26, 28) envelops the plate end flanges to form part of a manifold (26, 28) at each end of the plate pairs. End caps or plates (36, 40) close the open ends of the U-shaped channels to complete the manifolds, and inlet and outlet openings (30, 32) are formed in the manifolds as desired to complete the heat exchanger.

Description

technical field [0001] The present invention relates to a heat exchanger, in particular to a plate-fin type heat exchanger, such as a heat exchanger for cooling engine coolant on an internal combustion engine. Background technique [0002] In the past, heat exchangers for engine coolant, such as radiators, had a plurality of parallel and spaced apart flat tubes with cooling fins between them to form a core. The headers or headers at each end of the flat tubes on each side of the core are provided with openings through which the opposite ends of the flat tubes pass. The disadvantage of this structure is that the joints of flat tubes and headers are difficult to manufacture and are prone to leakage. [0003] One approach to overcoming these difficulties is presented in U.S. Patent No. 3,265,126 to D.M. Donaldson. In this patent, the header has a continuous longitudinal opening and the tubes have specially shaped ends that fit in this continuous opening, thus simplifying asse...
