| dc.description.abstract | Space pulse tube coolers are very efficient, but like all regenerative high frequency Stirling and pulse tube coolers, the cold head needs to be located near the compressor in order to minimize the input power to the cooler. For applications that require cooling some distance from the cooler or that require vibration isolation from the cooled object, the cooling can be effectively transferred with a fluid loop rather than with a higher mass conduction bar. This can greatly ease integration into a payload as well as readily transmit the cooling to multiple cooling points. In this paper we report on a proof of concept test in which we added cold reed valves to the pulse tube cold block of our flight proven high efficiency cooler (HEC) so that cold gas could be circulated without the need for an additional circulation pump and additional heat exchangers to cool the gas. In this test, the measured remote cooling and the parasitic heat loads were compared to our previously reported tests using warm reed valves. The two previous tests circulated gas from either a second circulator compressor or from the pulse tube compressor that also acted as a circulator and cooled the gas with a heat exchanger connected to the pulse tube cold head. | en_US |
