Abstract
An atmospheric heat exchange method and apparatus is provided that is simple and inexpensive to construct and made from readily available, low cost materials; that is adaptable to be configured for mounting to a wide variety of existing structures; and which is highly efficient, lightweight and readily collapsible to facilitate storage and shipment.
Claims8
An atmospheric heat exchanger comprising:
- a sealed container having front and rear walls both made of thin, pliable sheet material having substantially the same physical properties and having smooth inner surfaces capable of contacting each other in face-to-face relationship defining therebetween an unrestricted liquid passageway substantially throughout the inner dimensions of said walls, said container walls capable of conforming to the shape of its supporting structure;
- said container having liquid inlet and outlet means for circulating a liquid medium through said container;
- negative pressure means for maintaining said conformable film walls in close, uniform relation to said other wall to define a liquid passageway therebetween having a minimum thickness;
- whereby said minimum thickness passageway creates a venturi to uniformly spread the liquid over the entire passageway and to increase the velocity of the liquid flow therethrough to enhance the heat transfer between said walls and said liquid.

- said container having liquid inlet and outlet means for circulating a liquid medium through said container;
- at least one wall of said container being made of a thin pliable and conformable plastic film material;
- negative pressure means for maintaining said conformable film walls in close, uniform relation to said other wall to define a liquid passageway therebetween having a minimum thickness;
- said outlet means including a perforated pipe having a tubular netting material telescopically mounted thereover to prevent the pliable plastic film from blocking the discharge flow therethrough;
- whereby said minimum thickness passageway creates a venturi to uniformly spread the liquid over the entire passageway and to increase the velocity of the liquid flow therethrough to enhance the heat transfer between said walls and said liquid.
