Description

technical field [0001] The invention relates to a miniature thermoacoustic cooling module device, in particular to a miniature thermoacoustic cooling module device which uses thermoacoustic effect to dissipate heat or cool down electronic optoelectronic devices and chips. Background technique [0002] With the in-depth study of "high temperature" superconducting materials and high integrated circuit information technology, how to uniformly dissipate heat and eliminate hot spots in electronic and optoelectronic chips has become one of the key directions of new product research in electronic technology. It also puts forward an urgent demand for the miniaturization of refrigeration technology, which provides a good opportunity for the development of micro refrigeration technology. [0003] Micro-thermoacoustic refrigeration technology is a completely new type of refrigeration technology developed in response to the above requirements. Micro-thermoacoustic refrigeration is a re...
