Solid-state refrigeration prototype machine system based on shape memory alloy

The invention provides a solid-state refrigeration prototype system based on shape memory alloy sheet springs. Comprising a refrigeration mechanism based on a shape memory alloy spring sheet, a loading mechanism used for providing shape memory alloy deformation, a first heat exchanger, a second heat exchanger and a control mechanism used for monitoring the performance of the shape memory alloy spring sheet. The refrigerating mechanism comprises a shape memory alloy spring piece set, a refrigerating medium, a heat storage container, a refrigerating pump and a heat flow control valve. The invention further provides a manufacturing process, a heat treatment method and performance requirements of the shape memory alloy sheet spring. According to the solid-state refrigeration prototype system based on the shape memory alloy sheet spring, due to the fact that the solid material shape memory alloy is adopted as a medium, efficient refrigeration can be achieved, environmental pollution is avoided, and the dilemma of
