| Abstract: | A novel device of cryogenic heat transfer is proposed, which combines NCC and CH P together. The device has advantages of NCC and CHP, and eliminates the disadva ntage of NCC for its low thermodynamic efficiency. Furthermore, it has also the merit of a self-feedback process, which makes the object come back to the objec tive temperature quickly. In order to verify its performance, a cryogenic heat t ransfer device was designed and fabricated.The experimental results are compared with those simply cooled by a NCC or a CHP, which show the potential for furthe r applications. The device was applied for a power MEMS cooling successfully,and will be helpful to cooling not only for MEMS,but also for superconductors. |
