Abstract: A heat exchange assembly comprises a plurality of plates disposed in a spaced-apart arrangement, each of the plurality of plates includes a plurality of passages extending internally from a first end to a second end for directing flow of a heat transfer fluid in a first plane, a plurality of first end-piece members equaling the number of plates and a plurality of second end-piece members also equaling the number of plates, each of the first and second end-piece members including a recessed region adapted to fluidly connect and couple with the first and second ends of the plate, respectively, and further adapted to be affixed to respective adjacent first and second end-piece members in a stacked formation, and each of the first and second end-piece members further including at least one cavity for enabling entry of the heat transfer fluid into the plate, exit of the heat transfer fluid from the plate, or 180° turning of the fluid within the plate to create a serpentine-like fluid flow path between points o

Abstract: The present invention is directed to a thermal storage system and auxiliary air conditioning systems employing the same, said system employs a heat exchange assembly made from profile board or corrugated board which provides a cost efficient and light weight device for storing an energy storing medium and then using the same at desirable times to provide cooling.

Abstract: A heat exchange assembly including at least one plate, preferably made from profile board, having a plurality of channels therein for the flow of a heat exchange fluid in a first plane which may be flat or curved and at least one inlet and outlet angled up to 90.degree. with respect to the first plane.

Abstract: There is disclosed a high inlet internal artery for use with thermosyphon tubes having condenser and evaporator sections. The high inlet internal artery allows such thermosyphons to operate above previously known maximum power throughput limits by drawing working fluid away from a stagnant pool area at the top of the condenser section of the thermosyphon tubes and transporting that fluid back into the evaporator section of the thermosyphon tube out of contact with upward flowing vapor which could impede the return of condensate. The high inlet artery of the present invention allows the circulation of liquid through a closed path and promotes increased thermal efficiency.

Abstract: A thermosyphon heat exchanger having evaporator and condenser sections is provided which includes an internal bladder capable of defining an internal volume which is substantially equivalent to the internal volume of the thermosyphon, the bladder containing working fluid which acts to transfer heat being delivered to the evaporator section of the thermosyphon to the condenser section of the thermosyphon. The thermosyphon provided, including the internal bladder, is more easily constructed than known thermosyphons due the ease of pressure relief and there being no requirement of extreme cleanliness within the thermosyphon. Also provided is a method of constructing a thermosyphon in accordance with present thermosyphon.
