Embodiment Construction

[0017] The following detailed description of the invention is merely exemplary in nature and not restrictive of the invention or of the practice and use of the invention. Furthermore, there is no intention to be bound by any expressed or implied belief presented in the preceding background of the invention or the following detailed description of the invention.

[0018] see figure 1 , the COIL 20 is shown having a phase change heat exchanger 22 of the present invention for thermally regulating the fluid of the COIL 20, which may be one or more gases, liquids, or one or more gases and liquids mixture. Although the following detailed description of the invention describes the thermal conditioning of COIL 20 fluids, the phase change heat exchanger 22 may also be used to thermally condition one or more fluids for other lasers, or may be used in non-laser applications Thermodynamic regulation of fluids in .

[0019] COIL 20 uses chlorine gas (Cl 2 )26 with basic hydrogen peroxi...

Abstract

A phase-change heat exchanger (22) is provided for thermally conditioning a fluid. The phase-change heat exchanger includes, but is not limited to, conduits (60) configured to convey the fluid through the phase-change heat exchanger (22) and a foam structure (66) in thermal contact with at least one of the conduits (60). The foam structure (66) has ligaments (84) interconnected to form a three-dimensional reticulated structure of open cells (86). A phase-change material (88) is contained within the open cells (86) and the phase-change material (88) is configured to receive thermal energy of the fluid from the ligaments (84) of the foam structure (66).

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of US Application Serial No. 10 / 338,539, filed January 7, 2003. technical field [0003] The present invention relates generally to heat exchangers, and more particularly to phase change heat exchangers. Background technique [0004] Heat exchangers for thermal conditioning of solids, liquids, and / or gases are well known. There exist a variety of solid, liquid and / or gaseous solids, liquids and / or gases for heating and / or cooling a system or device over a sustained period of time or optimized for relatively short bursts of heat or cooling heat exchanger structure. For example, a Chemical Oxygen Iodine Laser (COIL) typically utilizes short bursts (ie, minutes or seconds) of heating and cooling to maintain a relatively constant temperature of a fluid and / or gas. [0005] Currently, short burst cooling and heating are provided respectively by evaporation of cryogenic fluids an...
