Abstract

The invention discloses a crank connecting rod mechanism for a refrigeration compressor and a working method of the crank connecting rod mechanism. Due to cooperative use of a first heat conduction seat, a second heat conduction seat and a third heat conduction seat, heat generated by friction between a first piston and an inner cavity and between a second piston and the inner cavity can be conducted, the influence of heat on work of the first piston and the second piston is eliminated, and the working efficiency of the refrigeration compressor can be effectively improved. Due to cooperative use of a first heat conduction outer pipe, a second heat conduction outer pipe, a first heat conduction inner pipe, a second heat conduction inner pipe, a connecting seat and a heat dissipation pipe, heat generated by rotation of a first connecting rod journal and a second connecting rod journal on a crankshaft can be conducted, and then the heat conduction efficiency of the crank connecting rod mechanism can be improved. According to all aspects of crank connecting rod mechanism for the refrigeration compressor and the working method of the crank connecting rod mechanism, the problems that theworking efficiency of the refrigeration compressor is poor due to heat generated by friction of the crank connecting rod mechanism and the heat conduction efficiency of the crank connecting rod mechanism is poor can be solved.
