Benefits of technology

[0012]It is a major advantage of this invention to be easily manufactured in large scale because of easily reproducible components.
[0036]It was concluded that series of repeating patterns would be better than a series of randomly located obstacles. Therefore, by using repeating simple forms, a more predictable result can be obtained no matter the number of variations in size and shape the heat transfer device needs to be.

Problems solved by technology

It is generally accepted in the scientific community that air cannot be as good a vector of transport and energy transfer for this type of system, much less be better, due to molecular mass and specific heat capacity of air being only a fraction of that of liquid.
So no one has seriously taken on the task of developing a more efficient air-liquid heat exchanger.

Embodiment Construction

[0048]A heat exchange system for use in liquid-gas heat exchange using solar energy is comprised of three (components: A solar heater panel (10), a double pipe (28), and a heat exchanger (14). Other components include a water pump (13) and a water tank (17).

[0049]Except for the fact that it uses air instead of water, the solar air-heater panel (10), is similar to solar liquid-heater panels. Sunlight passes through a sheet of transparent glass (16) and heats up a back panel (18) painted a dark color so as to generate as much heat as possible. There is a single circuitous path (20) defined by wall members (22) that snakes across the panel (10). The air is forced, by way of a fan (24), pushing air into an entry (23), passing over a plurality of baffles (26) which mixes the air so that it is evenly warmed up with minimal temperature variations, and coming out at an exit point (25). The air-heater panel (10) does not form part of this invention, it is just introduced here to show the gen...

Abstract

A heat exchanger is comprised of a plurality of chambers, wherein each of the plurality of chambers has a repeating pattern of shapes wherein each of the plurality of chambers consists of two opposite deflectors, wherein each deflector is a mirror image of its opposite deflector but shifted approximately half a the wall length. Each of the deflectors is defined by a specific sequence of components starting with a rounded wall from which extends a shear barrier and the wall is terminated by a diverter. The diverter, along with the shear barrier, forms a low pressure zone which creates a vortex. A coil for carrying a liquid wherein the coil consists of a long winding pipe forming tube bundles passing through all of the plurality of chambers.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to heat exchange systems but more particularly to a heat exchange system for use in liquid-gas heat exchange using solar energy.BACKGROUND OF THE INVENTION[0002]U.S. Pat. No. 4,210,202 discloses rows of heat exchange tubes that are supported by transversely disposed support strips having a plurality of V-shaped members interconnected end to end in a manner so that the strips act as a structural member supporting the weight of the tubes and additional support elements from all rows above a given row. Each leg of each V-shaped member has a generally triangular tab bendable out of the plane of its associated leg. Rows of heat exchange tubes are supported by transversely disposed support strips having a plurality of V-shaped members interconnected end to end in a manner so that said strips act as a structural member supporting the weight of the tubes and additional support elements from all rows above a given row. Each ...
