Heat regenerator of heat-regenerating type low-temperature refrigerator

Abstract

The invention discloses a heat regenerator of a heat-regenerating type low-temperature refrigerator, which comprises a sleeve of a heat regenerator and a filler of the heat regenerator. The heat regenerator is characterized in that the sleeve of the heat regenerator is firstly filled with the radial filler and secondly filled with the axial filler, which are alternately filled, and finally with the radial filler; the radial filler is formed by tightly paving and overlapping 20-40 pieces of circular metal nets layer by layer, wherein the diameter of each piece of the circular metal net is equal to the inner diameter of the sleeve of the heat regenerator; the axial filler is formed by tightly winding through a square metal net piece along an edge metal wire; and the radial filler and the axial filler are tightly contacted with the inner wall of the sleeve of the heat regenerator. The depth m of the axial filler is larger than the depth n of the radial filler, and the voidage of the axial filler is less than that of the radial filler. The heat regenerator can realize high heat regenerating efficiency, low flow resistance, small axial heat-guiding loss and smaller empty cubage, and greatly improves the efficiency of the heat-regenerating type low-temperature refrigerator.

AI Technical Summary

Benefits of technology

In this patented design for an improved type of regulator used in cryo-refrigerating systems that improves its performance over existing designs while reducing thermal conductivity losses caused by airflow turbulence or other factors such as pressure fluctuations during operation. It achieves these improvements without adding extra components like pumps or valve plates.

Problems solved by technology

This patents discuss various technical problem addressed in these documents relates to optimizing the design of an ice making device called a regulator. Specifically, there exist different types of regulatory elements like regulating valves and resistors within the regulated chamber. These factors can lead to poor heat recover efficiencies due to insulation issues caused by imperfections during manufacturing processes. Additionally, current methods involve impregnated films or woven metallized fibers, but they may also be affected by the presence of nonuniform fills in certain areas leading to reduced heat dissipativity and void volumes.
