Abstract

The deep cooling loop heat pipe includes main evaporator and liquid chamber connected serially via connecting pipe. The main evaporator has casing of stainless steel pipe with axial grooves in the inside surface and main tubular liquid absorbing core of sintered stainless steel powder. The liquid chamber has stainless steel wire screen filled between the right end cap and the casing. There are also capillary connecting part, which has central inside hole, is set inside the hole of the main liquid absorbing core and extends via the connecting pipe to the liquid chamber, and annular coarse stainless steel wire sheet filled between the capillary connecting part and the liquid chamber casing. The present invention can avoid reverse flow of the work medium to ensure the successful starting of deep cooling loop heat pipe, and can raised the heat transferring limit of deep cooling loop heat pipe for stable operation performance.

Description

technical field [0001] The invention belongs to a circuit heat pipe in the technical field of refrigeration and low temperature, and in particular relates to a cryogenic circuit heat pipe for improving the integration relationship between a cryogenic refrigerator and a cooled device in a low-temperature integrated system for space. Background technique [0002] With the development and wide application of cryogenic refrigerator technology, it becomes more and more obvious that it is necessary to consider the problem of how to effectively transmit cold energy over long distances. Therefore, the cryogenic refrigerator and the cooled device should be integrated together as a system rather than a device, which can enhance the cooling capacity of the refrigeration system. [0003] At present, the common method of connecting the refrigerator and the cooled device is to use copper rods for heat conduction. The disadvantage is that when the heat transmission distance becomes longer,...
