Rotor type Stirling refrigerator and working method

Abstract

The invention discloses a rotor type Stirling refrigerator and a working method, and belongs to the field of refrigeration equipment. The rotor type Stirling refrigerator comprises a special-shaped triangular rotor and a rotor containing cavity, a hole allowing the special-shaped triangular rotor to be communicated with the outside is formed at the bottom of the rotor containing cavity, the special-shaped triangular rotor is provided with a tubular extension object, an outer gear is arranged on the tubular extension object, and an eccentric shaft is inserted into the tubular extension object and driven by a motor through a coupler. The outer gear is matched with an inner gear fixed to the bottom end of the rotor containing cavity, so that it is guaranteed that when the motor drives the special-shaped triangular rotor to move in the rotor containing cavity through the eccentric shaft, the motor and the special-shaped triangular rotor are attached, four through holes are formed in an embedded sealing end cover, and two U-shaped heat exchange pipe sets are arranged on the four through holes respectively. According to the rotor type Stirling refrigerator, the vibration problem of a traditional rhombus transmission and crank connecting rod type Stirling refrigerator is avoided, the efficiency is improved through rotor driving, and the structural form is more compact. An internal working medium is in a sealed state and is isolated from the outside, and no phase change or throttling process exists during circulation.

Description

technical field [0001] The invention relates to a refrigerator and a working method, in particular to a rotor type Stirling refrigerator and a working method used in industrial and mining enterprises. Background technique [0002] The Stirling refrigerator is a refrigerator based on the Stirling refrigeration cycle. There is no phase change or throttling of the working medium during operation, which greatly improves the efficiency and makes it easier to achieve low temperatures. Nowadays, the development of Stirling refrigerators is relatively mature, and can achieve lower temperatures in a short period of time, but the Stirling refrigerators with relatively mature technology are all piston or two-stage piston refrigerators, and the volume change inside the body depends on The reciprocating motion of the piston changes the control, and the problems of noise and vibration are more serious. Due to its working principle, the Stirling refrigerator can realize refrigeration at l...

Problems solved by technology

However, the combination of the cylinder and the piston is essentially the reciprocating motion of the piston in the linear direction, which will cause a great vibration problem of the whole machine, and the cooperation of the piston and the cylinder cannot achieve high frequency movement. When the internal working fluid pressure When it is determined, it is difficult to increase the input power of the body to output more cooling capacity without high-frequency exercise
