Benefits of technology

[0005]The invention provides for such a heat exchanger assembly and wherein the ratio of the cross-over opening area of the cross-over plate to the upstream cross-sectional area of the upstream flow paths is in the range of XXXXX:XXXXX to XXXXX:XXXXX. This ratio maximizes the efficiency of the heat exchanger assembly by ensuring optimum fluid flow without creating a pressure drop in the coolant flowing through the cross-over plate. A large pressure drop often has the undesirable effect the effect of cooling and / or re-condensing the coolant.

Problems solved by technology

A large pressure drop often has the undesirable effect the effect of cooling and / or re-condensing the coolant.

Embodiment Construction

[0019]Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, a heat exchanger assembly 20 for transferring heat between a coolant and a stream of air is generally shown in FIGS. 1-3. The heat exchanger assembly 20 could be a number of different kinds of heat exchangers, e.g. an evaporator, a condenser, a heat pump, etc.

[0020]The heat exchanger assembly 20 includes a first manifold 22, generally indicated, extending along an axis A between first manifold ends 24. A second manifold 26, generally indicated, extends between second manifold ends 28 in spaced and parallel relationship with the first manifold 22.

[0021]A first partition 30 is disposed in the first manifold 22 and extends axially along the first manifold 22 between the first manifold ends 24 to define a first upstream section 32, 34 on one side of the first partition 30 and a first downstream section 36, 38 on the other side of the first partition 30. A second partition 40 ...

Abstract

A heat exchanger including a pair of manifolds. An inlet is disposed on one of the ends of the first manifold. A core extends between the manifolds for conveying a coolant therebetween and for transferring heat between the coolant and a stream of air. A cross-over plate is disposed in one of the manifolds to divide the associated one of the manifolds into an upstream section and a downstream section. The cross-over plate presents a plurality of orifices defining a cross-over opening area for establishing fluid communication between the upstream and downstream sections of the associated manifold. The cross-over opening area continuously increases along an axis away from the inlet. The ratio of the total cross-over opening area to the upstream cross-sectional area of the tubes of the core is in the range of XXXXXXXX:XXXXXXX to XXXX:XXXXXX.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]A heat exchanger assembly for transferring heat between a coolant and a stream of air.[0003]2. Description of the Prior Art[0004]U.S. Pat. No. 6,272,881, issued to Kuroyanago et al. on Aug. 14, 2001 (hereinafter referred to as Kuroyanago '881), shows first and second manifolds spaced from one another A cross-over plate is disposed in one of the manifolds for dividing the associated manifold into an upstream section on one side of the cross-over plate and a downstream section on the other side of the cross-over plate. The cross-over plate defines at least one orifice for establishing fluid communication between the upstream and downstream sections of the associated manifold. A core extends between the first and second manifolds for transferring heat between the stream of air and the coolant. The core includes a plurality of tubes defining a plurality of upstream flow paths and a plurality of downstream paths. The upstrea...
