Benefits of technology

The patent describes a modular multi-channel tube heat exchanger that can be customized for different refrigerant flow paths. The heat exchanger modules are made of aluminum and have a unique design with multiple flow paths and header configurations. The aluminum headers can be connected to each other using copper or aluminum tubing, and can be attached using mechanical or thermal bonding connections. The technical effects of this invention include improved heat transfer efficiency, flexibility in refrigerant flow paths, and reduced weight and cost of the heat exchanger.

Problems solved by technology

As a consequence, the overall size of the heat exchanger is limited by the size of the available brazing furnaces.

Abstract

A modular multi-channel tube heat exchanger includes a plurality of aluminum heat exchanger modules selectively connected in fluid communication by interconnecting tubing. Each heat exchanger module includes an aluminum inlet header, an aluminum outlet header and a plurality of aluminum heat exchange tubes extending longitudinally therebetween. Each of the plurality of heat exchange tubes may have a plurality of flow paths extending longitudinally in parallel relationship from an inlet end thereof in fluid communication with the inlet header to an outlet end thereof in fluid communication with the outlet header.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to heat exchangers having a plurality of heat transfer tubes extending between a first header and a second header, also sometimes referred to as manifolds, and, more particularly, to modular multi-channel tube heat exchangers.[0002]Refrigerant vapor compression systems are well known in the art. Air conditioners and heat pumps employing refrigerant vapor compression cycles are commonly used for cooling or cooling / heating air supplied to a climate-controlled comfort zone within a residence, office building, hospital, school, restaurant or other facility. Refrigerant vapor compression systems are also commonly used for cooling air or other secondary fluid to provide a refrigerated environment for food items and beverage products within, for instance, display cases in supermarkets, convenience stores, groceries, cafeterias, restaurants and other food service establishments.[0003]Commonly, these refrigerant vapor compression s...
