DESCRIPTION

[0030]The specification generally relates to heat exchanger (2), such as a charge air cooler for reducing the temperature of air inflow to a combustion engine.

[0031]The heat exchanger (2) is typically placed in an air intake manifold (4), as shown in FIG. 1, which has a cavity (6) for placing the heat exchanger (2) through an opening (8). Incoming air enters the manifold (4) through an air intake aperture (10) and passes the heat exchanger (2) before being directed to the combustion engine.

[0032]The heat exchanger (2) used in accordance with the disclosure is not particularly limited. In one example embodiment, as shown in FIGS. 2 and 4, the heat exchanger (2) has a plurality of spaced-apart plate pairs (12), where each plate pair defines a flow passage for the flow of a first fluid, such as a coolant. A fluid manifold (14) having an inlet (16) and outlet (18) (FIGS. 2 an...

Abstract

A heat exchanger containing a plurality of spaced-apart plate pairs, where each plate pair defines a flow passage for the flow of a first fluid. In addition, one or more fins are thermally coupled and sandwiched by the spaced-apart plate pairs for flow of a second fluid. And, a fluid manifold that is fluidly coupled to the spaced-apart plate pairs at a manifold end of the spaced-apart plate pairs is provided. Further, a tab that extends from a flange end of a first plate of the first plate pair and in contact with a second tab extending from a flange end of a second plate of a second plate pair for providing a fluid flow blocker. Also, provided is a heat exchanger assembly containing a housing and the heat exchanger described herein.

Description

FIELD[0001]The specification relates to a heat exchanger having an air bypass blocking tabs, and a heat exchanger assembly having a housing and the heat exchanger described herein.BACKGROUND[0002]Charge air cooler heat exchangers are well known in the art for mounting along the flow path of charge air supplied to a combustion engine. This charge air typically comprises ambient air which has been compressed by apparatus such as a supercharger or turbocharger to provide an increased mass flow of air to the engine to permit the engine to combust increased quantities of fuel and thereby operate at an increased level of power and performance. However, compression of ambient air also elevates the air temperature such that the charge air has a relatively high temperature which, if not reduced, undesirably increases total engine heat load. It is therefore desirable to cool the charge air prior to supply thereof to the engine, and charge air coolers are provided for this purpose.[0003]In gen...
