Abstract

The invention relates to the technical field of energy-saving devices in refrigeration technologies, and discloses a reciprocating expansion mechanism. The reciprocating expansion mechanism comprisesa cylinder body, a cylinder head, a rotary disc and a rotary shaft, wherein a piston capable of carrying out up-down reciprocating movement in the longitudinal direction of the cylinder body is arranged in the cylinder body, and an intake port and an exhaust port are formed in the upper end surface of the cylinder body separately; an intake cavity and an exhaust cavity are formed in the cylinder head separately, an intake hole and an exhaust hole are formed in the bottom wall of the cylinder head separately, the intake hole and the intake port are oppositely formed in the up-down direction andform an intake channel, and the exhaust hole and the exhaust port are oppositely formed in the up-down direction and form an exhaust channel; the rotary disc is arranged between the cylinder head andthe cylinder body, and a first through port and a second through port are formed in the rotary disc separately; and the rotary shaft is arranged on the upper surface of the rotary disc and capable ofdriving the rotary disc to carry out synchronous circumferential rotation to open and close the intake channel and the exhaust channel in a switchover manner. The reciprocating expansion mechanism has the advantages of being high in energy efficiency utilization rate and sealing performance.

Description

technical field [0001] The invention relates to the technical field of energy-saving devices in refrigeration technology, in particular to a reciprocating expansion mechanism. Background technique [0002] The reciprocating expansion mechanism has been widely used in cryogenic fields as a low-temperature machine for producing cold, such as hydrogen and helium liquefaction, air separation, etc. In the field of refrigeration, with the signing of the Montreal Protocol, traditional CFCs (hydrogen fluorides) and HCFCs (refrigerants) are being phased out due to their detrimental effects on the ozone layer and the greenhouse effect, and the air-conditioning industry is facing the development of alternatives. In view of the challenges of new chemical compounds, which also imply unpredictable hazards, people are focusing on natural refrigerants, among which CO with excellent environmental protection characteristics and good flow and heat transfer performance 2 Become the most import...
