| Abstract: |
| The cool-down performance of a miniature mixed refrigerant J-T refrigerator was experimentally investigated. A miniature mixed refrigerant J-T refrigerator driven by an Aspen mini-compressor was developed, and preliminary test results were presented. The miniature J-T cryocooler was constructed with stainless steel capillary tubes with specific inner diameter of 0.3mm. By using multicomponent mixed refrigerant, the miniature J-T refrigerator can reach no-load temperature of 180K. Driven by the mini-compressor, such miniature J-T cryocoolers have good perspective in such applications as mobile biomaterials preservation, cryosurgery and electronic devices cooling, etc. |
