Abstract: A system and method for maintaining a temperature of a power system using a cooling system that includes an impeller and a phase change material. During normal operation of the cooling system, heat that is generated by the operation of an electronic device(s) of the power system can be transferred primarily by conduction through an upper base plate and fins of a heat sink, and dissipated via forced convection that is generated by the impeller. Additionally, the phase change material is positioned outside of a main heat flux path of the heat sink such that, during normal operation of the cooling system, the phase change material does not provide a heat flux obstruction. In the event of an impeller failure, the phase change material provides at least a temporary cooling source for an extended period of time via the relatively large latent heat capacity of the phase change material.

Abstract: The invention relates to an HVAC apparatus, method, and system. Aspects of the invention include a supplemental heat source with an air handler unit for a conventional forced air heating and cooling system. The supplemental heat source in one example is a hydronic subsystem. It can be used alone or to supplement the forced air subsystem. Another aspect of the invention includes an air handling subsystem that has a housing that can be highly flexible in configuration and installation. The housing can support internal components, including a hydronic or other supplemental heat source with the forced air components. At least two sides of the housing can be configured for access for maintenance and repair. A control system can be designed to eliminate need for defrost cycle for forced air refrigeration-type subsystem and/or for better maintenance for comfort in the air conditioned space.

Abstract: A vapor chamber and a heat dissipation device with the vapor chamber are provided. The vapor chamber includes a first plate, a second plate, a first capillary strip, a first communication structure and a working medium. An accommodation space is defined by the first plate and the second plate collaboratively. The first capillary strip is installed in the accommodation space. The accommodation space is divided into a first region and a second region by the first capillary strip. The working medium is accommodated within the accommodation space. The working medium flows between the first region and the second region through the first communication structure. Since the working medium is guided to flow in the accommodation space by the first capillary strip and the first communication structure, the heat dissipating efficacy is enhanced.

Abstract: A heat-wing includes: a sealed hollow chamber including two plates and a frame connecting the two plates; a capillary structure layer closely attached to an inner surface of the chamber; and a phase transition working medium sealed in the chamber. A portion of the frame or a portion of a periphery of one of the two plates serves as an evaporation area of the heat-wing, and the rest portion of the chamber serves as a condensation area of the heat-wing. The heat-wing has an increased vapor passage area, liquid working medium flow-back passage width and condenser heat transfer area and a reduced evaporator center-to-edge distance, and is hence capable of achieving a great improvement in heat transfer limit and heat flux density.

Abstract: A heat exchanger is characterized by having two or more fluid flow circuits, each formed by multiple small cross-section “micro-tubes” contained within a surrounding metal structure, or “metal matrix.” Its function is to efficiently transfer heat from one fluid to another in a highly compact assembly. Most any metal or metal alloy can be considered for the micro-tubes. The micro-tubes, while typically arranged in alternating layers of alternating flow circuits, may be organized in any number of arrangements including co-linear and at cross angles to provide for co-flow, counter flow and cross flow. The metal matrix, is provided in one embodiment by a metal or metal alloy powder consolidated in a hot isostatic pressing (HIP) process. This process also joins the tubes together and to the matrix itself, producing a monolithic structure.
