A cooling system for a photovoltaic panel including micro flat heat pipes (HP) integrated with thermoelectric generators (TEG) and a cooled water reservoir for cooling the working fluid in heat pipes. The cooled water in the reservoir is pumped from the condensate pan of an air conditioner. Experimental results show that cooling system reduced the average temperature of the panel by as much as 19? C. or 25%. Further, the output power of the photovoltaic panel increased by 44% when the photovoltaic panel was used in a very hot climate (30-40? C.). An additional two watts of power was generated by the TEGs.

A thermally regulated component is an optical element or chuck for holding an optical element, or a stage for same, or combination thereof. The component has first and second heat-transfer zones. The first has a first component surface that receives a heating influence such as incident electromagnetic radiation. The second has a second component surface. A conduit circuit extends in the component serially through the first and second heat-transfer zones, back to the first heat-transfer zone, and contains an electrically conductive liquid (e.g., liquid metal). A vibration-free pump (e.g., MFD pump) coupled to the conduit circuit induces flow of the liquid through the circuit. A heat-exchanger is in thermal contact, but not actual contact, with the second component surface. Thus, heat delivered to the second heat-transfer zone by the liquid flowing in the conduit circuit flows from the second component surface to the heat-exchanger.

The present technology is directed generally to phase change materials for cooling enclosed electronic components, including for solar energy collection, and associated systems and methods. In particular embodiments, a system directs warm air through an airflow path in thermal communication with a phase change material to liquefy the phase change material and cool the air. The system also directs the cool air into thermal communication with electronic components to cool the electronic components via conduction and/or convection.

A modular solar air heater comprises an extruded metal frame having fingers operable to secure a glazing, an absorber, and an insulating back sheet to the frame. The heater may also operate as a cooler. The heater further comprises an active air circulation system, such as a fan, which may be coupled with an air inlet of the heater. The heater has an air outlet and may further include a bypass channel to direct the airflow alternatively through one or both the bypass channel and the air outlet. A heating element and a cooling element may be coupled with the air outlet to further heat and also cool the air through the air outlet, respectively. A photovoltaic panel may be included to provide electrical power to the heater.

An optical heat exchanger and an associated system and method are provided to allow a vehicle, such as an unmanned air vehicle, a rocket or the like, to deliver more payload at a lower cost. The optical heat exchanger includes a support surface defining a plurality of tapered openings. Each tapered opening tapers from the first size proximate an outwardly facing end of the opening to a second smaller size proximate an inwardly facing end of the opening. The inwardly facing end of each tapered opening is in communication with the propellant. The optical heat exchanger also includes a plurality of lenses with each lens positioned proximate the outwardly facing end of a respective opening. Each lens is configured to receive an electromagnetic energy beam and concentrate the majority of the electromagnetic energy beam through the inwardly facing end of the respective tapered opening, thereby heating the propellant.
