Abstract

The invention relates to a heat tube type pulse tube refrigerating machine cold air transfer arrangement wherein the condensation section of the heat tube is coupled to the refrigerating machine's fixed junction, the evaporation section is coupled with the refrigeration device, a condensation section end cover can be arranged on the condensation section to be coupled and contact with the refrigerating machine's fixed junction, and an evaporation end cap can be arranged on the evaporation section to be coupled with the refrigeration device, the cold air will be transferred to the cooling device from the fixed junction through the heat tube. The arrangement by the invention has high heat-transfer capability and can solve the problem of pulse tube refrigerating machine high power cold air transfer.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and low temperature, and in particular relates to a cold delivery device for a heat pipe type pulse tube refrigerator. Background technique [0002] The pulse tube refrigerator is a small low-temperature refrigerator widely used in the cooling of infrared detectors and high-temperature superconducting devices. The thermal connection device between the cold head of the pulse tube refrigerator and the cooled device should have the following requirements: high heat transfer capacity, small temperature difference between both ends, large transmission distance, thermal diode characteristics and bendability for easy installation, etc. The present invention provides a new connection device that meets the above requirements and replaces the traditional thermal connection device (metal rod), that is, the cold delivery device of the heat pipe type pulse tube refrigerator, so ...
