Abstract

The invention provides a throttling refrigerator. The throttling refrigerator comprises a first layer plate, a middle layer plate and a second layer plate; the middle layer plate is arranged between the first layer plate and the second layer plate; a first spiral channel, a curved channel and a first through hole are formed in the face, facing the first layer plate, of the middle layer plate; the first through hole is located in the center of the first spiral channel; the curved channel comprises at least two throttling channels, and the sum of the sectional areas of the throttling channels is smaller than the sectional area of the first spiral channel; the throttling channels communicate with the first spiral channel and the first through hole; a second spiral channel is formed in the face, away from the first layer plate, of the middle layer plate; the center of the second spiral channel communicates with the first through hole; a second through hole is further formed in the middle layer plate and communicates with the end, away from the center, of the first spiral channel; and a third through hole and a fourth through hole are formed in the second layer plate, wherein the third through hole communicates with the second through hole, and the fourth through hole communicates with the end, away from the center, of the second spiral channel. The reliability of the throttling refrigerator can be improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a throttling refrigerator. Background technique [0002] The highly miniaturized new micro refrigerator (micro miniature refrigerator, MMR) proposed by Professor W·A·Little of Stanford University in the 1980s has had a major impact in the field of electronic cooling. This new type of refrigerator can even make the working temperature lower than the normal boiling point of the working substance by using technologies such as evaporation chamber suction or ejector. This ultra-miniature throttling refrigerator is made by micro-electro-mechanical system (Micro-Electro-MechanicalSystem, MEMS) photolithography technology, which has the characteristics of novel technology, small size, low vibration, and non-magnetic. It is used in highly sensitive detection elements, Electronic instruments, precision gauges, and optical components are widely used. For example, the University of Ca...
