Embodiment Construction

[0032] The embodiment of the present invention aims at the problem of lagging temperature adjustment of the existing self-adjusting throttling refrigerator through the bellows or memory alloy, and the sliding block is set on the needle body of the valve needle to play the role of radially limiting the valve needle, so that The needle tip of the valve needle is always aligned with the area of ​​the orifice axis. The spring has two functions, one is to prevent the valve needle and the slider from moving freely and hit the orifice, and the other is to cooperate with the stepping motor shaft to adjust the relative position of the valve needle and the valve body. After the stepper motor shaft receives the pulse signal, it can extend or contract in the axial direction, thereby controlling the opening of the needle valve mechanism and realizing the adjustment of the cooling flow. That is, the throttling refrigerator in the embodiment of the present invention uses a motor and a drive ...

Abstract

The invention discloses an active control type self-adjusting throttling refrigerator. The active control type refrigerator of the invention directly adjusts the flow rate of the refrigerator according to the temperature signal fed back by the object to be cooled, which overcomes the traditional bellows or memory The alloy self-regulating throttling refrigerator adjusts the hysteresis problem, and at the same time, the assembly and debugging are simpler, and the service life is longer than that of the bellows self-regulating refrigerator.

Description

technical field [0001] The invention relates to the technical field of low-temperature refrigeration, in particular to an actively controlled self-regulating throttling refrigerator. Background technique [0002] Refrigerators that utilize high-pressure gas throttling and cooling to achieve refrigeration are called throttling refrigerators or Joule-Thomson refrigerators (ie, J-T refrigerators). Because throttling refrigerators can achieve lower cooling temperatures, and have the advantages of fast start-up, small size, and light weight, they are widely used in low-temperature medical, aerospace, and infrared detection fields. [0003] Self-adjusting throttling refrigerator refers to a refrigerator that can realize automatic adjustment of cooling temperature, cooling flow rate and cooling power. At present, there are two common self-adjusting technical routes, bellows self-adjusting type and memory alloy self-adjusting type. The bellows is a thin-walled elastic element, whi...
