Abstract: A fluid phase change thermal management cooling method and apparatus for removing heat from a source of heat, the method comprising the steps of: filling a cooling chamber with volume V1 of a fluid phase change thermal management cooling apparatus with a fluid in its liquid phase; increasing the volume of the cooling chamber to volume V2 to va-pourise a portion of the fluid from its liquid phase to its vapour phase such that there is substantially only the fluid in its liquid phase and fluid in its vapour phase within the volume V2; allowing a dwell time that provides for at least some of the fluid in its liquid phase that has contact with a heated surface of the cooling chamber to be vaporised; and repeating the steps where timing of the steps and dwell time between steps is selected to control heat build-up within selected limits.

Abstract: A machine for a temperature regulation arrangement that includes a closed area within the machine leading a temperature regulating chamber positioned adjacent a heat source, in which there are a number of liquid collectors arranged so that each has a feed take off that provides a elevated passage way from one liquid collector to the next.

Abstract: The invention relates to a method of cooling machines. Typically, the method of cooling is useful in the cooling of dies used in the moulding of plastics or metals. The method relies upon taking advantage of the latent heat of vaporisation of a cooling liquid. A liquid is maintained in a closed chamber in a die such that the liquid is in contact with the surfaces to be cooled and a space above the liquid surface is available. The pressure in the space is adjusted, typically by vacuum equipment, such that the boiling point of the liquid is adjusted to a level which enables the principle cooling process to involve latent heat.

Abstract: An arrangement to assist in heat transfer through a mold for applications such as injection molding of plastics material including at least one closed chamber within the mold, the chamber being only partially filled with fluid and a remainder of the chamber being filled with substantially only vapor of the fluid within the chamber, at least a portion of the chamber being positioned to transmit heat from a targeted location of the mold into fluid within the chamber, and condensing means adapted by reason of heat exchange to effect condensation of vapor within the chamber, the mold being arranged in that the fluid, such as water, is arranged to be held in the chamber in such a way that the fluid will be distributed to reach or be held at different heights within the chamber.

This is achieved in one case by the addition of a foaming agent in the liquid. In another case by having a flock attached to the inner surface of the chamber.
