Closed-loop cycle cryogenic electronics cooling system with parallel multiple cooling temperatures

Abstract

An closed single-loop low-energy/energy-independent cryocooler that removes high quantities of heat from a large area while utilizing a design that allows multiple temperatures on multiple cooled areas in parallel to allow for use on complex electronics which have different preferred operating temperatures. An energy independent design is a simple TEG based variation of the standard invention design. Said system allows for different uses such as for the cooling of over-clocked computer systems working at high heat loads, superconducting circuits, and/or the efficient cooling of temperature dependent devices such as laser diodes and etc. The said cooling system comprises of a hydraulic or pneumatic driven cylindrical single piston gas compressor, several multi-stage thin-film thermoelectric coolers (TEC), several thin-film single-stage high temperature thermoelectric generators (TEG), an enclosure with hollow passages inside the walls or attached loops of coiled copper tubes, a multi-way heat exchanger, and a evaporator.
