Embodiment Construction

[0016] Referring to the drawings, there is generally shown a heat exchanger assembly 20 for dissipating heat, wherein like numerals indicate corresponding parts throughout the several views.

[0017] The heat exchanger assembly 20 includes a first header, generally designated 22 , having an inner surface 24 and is generally circular in cross-section. The first header 22 is along the first header axis A 1 The first manifold extends between a pair of ends 26 to define a first cavity 28 . The second header 30 is generally indicated and is generally circular in cross-section. The second header 30 is along the second header axis A 2 Instead, the second header extends between a pair of ends 32 to define a second cavity 34 . Such as image 3 As shown in the second header axis A 2 Preferably parallel to the first header axis A 1 .

[0018] In the following, an exemplary embodiment of a heat exchanger assembly 20 is described wherein the first header 22 is the outlet header 22 an...

Abstract

The present invention relates to a distributor tube subassembly. Specifically, a heat exchanger assembly includes an outlet header extending along an outlet axis to define an outlet cavity and an inlet header defining an inlet cavity. A plurality of refrigerant tubes extends from the inlet header through the outlet header and into the outlet cavity. A collector conduit is disposed in the outlet header and includes a conduit body portion and at least one conduit end portion interconnected by a conduit transition portion with the conduit body portion being offset from the conduit end portion. The conduit body portion is engaged to an interior surface of the outlet header to space the conduit body portion from the refrigerant tubes extending into the outlet header and the conduit end portion is coaxial with the outlet header axis to provide a central outlet for the refrigerant vapor.

Description

technical field [0001] Cross References to Related Applications [0001] This application claims the benefit of Application Serial No. 61 / 020,040 filed 01 / 09 / 2008. [0002] The present invention relates generally to heat exchangers and methods of making the same, and more particularly to heat exchangers of the type comprising a plurality of refrigerant tubes extending between an inlet header and an outlet for Refrigerant is transported from the inlet header to the outlet header. Background technique [0003] Due to its high performance, automotive-sized brazed plate heat exchangers are currently being developed for residential air conditioning and heat pump applications. Automotive type heat exchangers typically utilize a pair of headers, with the refrigerant tubes defining fluid channels interconnecting the headers. Residential heat exchangers are typically larger than automotive heat exchangers and typically require headers that are two to five times longer than typical...
