AI Technical Summary

Benefits of technology

The invention allows for a heat exchanger to have a faster heat transfer rate without making it bigger. This is because the coils are nested, which means more coils can be put in without making the heat exchanger bigger. This results in more heat transfer between the fluid and the environment.

Problems solved by technology

The effective rate of heat transfer between the fluid and the outside environment are limited by the amount of coils the are in the heat exchangers.

Embodiment Construction

[0020]FIGS. 2 through 9 represent a nested heat exchanger assembly 10 according to non-limiting embodiments of the present invention. The heat exchanger assembly 10 is adapted to contain a fluid within coils 12 for promoting heat exchange between the fluid and the environment surrounding the coils 12. Suitable fluids include, but are not limited to, CO2, propane, and other gasses and liquids commonly used for heat exchange. The heat exchanger assembly 10 may be formed of any suitable material, for example, ferris metal, non-ferris metal, plastic, and glass. For convenience, consistent reference numbers are used throughout the figures to identify the same or functionally equivalent elements. To facilitate the description of the heat exchanger assembly 10, the terms “front,”“back,”“side,”“above,”“below,” etc., are used herein to refer to the orientation of a heat exchanger to earth, are relative terms that indicate the construction, installation and use of a heat exchanger, and theref...

Abstract

A heat exchanger assembly includes at least first and second coils adapted to contain a fluid therein and at least two support members securing the coils. Each of the first and second coils are individually formed of at least one tube including an inlet at an uppermost extent thereof and an outlet at a lowermost extent thereof and include a vertical column containing a plurality of horizontal rows and a plurality of bends at opposite ends of the horizontal rows and fluidically interconnecting the horizontal rows thereof in series to define a serpentine configuration. The first and second coils are adjacent each other and nested so that the horizontal rows of the first coil are parallel to the horizontal rows of the second coil and at least some of the horizontal rows of the first coil are disposed between adjacent pairs of the horizontal rows of the second coil.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 610,269, filed Mar. 13, 2012, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention generally relates to heat exchangers. More particularly, this invention relates to a heat exchanger having coolant tubes that overlap.[0003]Heat exchangers are widely used in various industries in the form of radiators for cooling motors, engines, and steering, transmission and hydraulic fluids, condensers and evaporators for use in air conditioning systems, and heaters. In their most simple form, heat exchangers include one or more passages through which a fluid flows while exchanging heat with the environment surrounding the passage. In order to efficiently maximize the amount of surface area available for transferring heat between the environment and fluid, the design of a heat exchanger is typically of a tube-and-fin ty...
