Embodiment Construction

[0025] Accompanying drawing is the specific embodiment of the present invention;

[0026] Below in conjunction with accompanying drawing, content of the present invention is described in further detail:

[0027] refer to figure 1 , figure 2 (a,b,c), image 3 Shown in (a, b), the present invention comprises upper end cover 4, upper end cover 4 and upper intermediate case 5 are fixed together by screw, upper intermediate case 5 and lower intermediate case 10 are fixed together by screw, lower end cover 9 It is fixed together with the lower middle casing 10 by screws, and the outer rings of the bearings 2 and 3 are fixed by the upper end cover 4 and the upper middle casing 5, so that the bearings 2 and 3 cannot move up and down in series, and the gas distributor rotor 1 can rotate freely. But it cannot move up and down. A motor 7 is fixed inside the upper end cover 4, and the rotating shaft of the motor 7 has a supporting wheel 8. A gas distributor rotor 1 is arranged inside...

Abstract

Disclosed is a back pressure axial flowing air wave refrigerator, comprising upper middle shell linked to upper end cover and linked together with lower middle shell which is linked to lower end cover an electric machinery with wheels on its rotating shaft is fixed in upper end cover, air distributor rotor with wheels is installed in upper end cover and upper middle shell and its chassis has air exhausting holes and air feeding holes which are linked to air distributor air-in cavity and the holes can be linked to pulse tube alternately, impeller fitted with air distributor rotor, air-in hole on upper end cover, air exhausting pipe on upper middle shell. Its lower middle shell and upper cover plate are linked and shock wave absorption cavity comprised of lower end cover and lower cover plate is linked to another end of pulse tube. The invention has compact structure, high heat exchange efficiency and can maintain kinetic energy for refrigerator work and air recovery.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a back pressure axial flow air wave refrigerator. Background technique [0002] Gas wave refrigerator, also called heat separator, is a kind of refrigeration machinery invented by French ELF company and BERTIN company from the late 1960s to the early 1970s. This new type of refrigeration machinery has the advantages of simple structure, easy processing, convenient operation and maintenance, and low cost. Low cost, not afraid of working with liquid, strong adaptability to working conditions, etc. Its heat efficiency, domestic machine is 40-70%, foreign report can reach 80-90%. Therefore, after the French NAT company (composed of ELF and BEREIN in conjunction with the French Petroleum Research Institute in the mid-1970s) released its research results, it was soon introduced, developed and applied in countries such as Japan, China and the former Soviet Union. Now, it is mainly used for dehydratio...
