WASTE HEAT ENERGY RECOVERY APPARATUS USING SHAPE MEMORY ALLOY REFRIGERANT CIRCULATION SYSTEM OF AIR CONDITIONER EQUIPPED WITH THE SAME AND COOLING APPARATUS FOR ENGINE EQUIPPED WITH THE SAME

摘要

A waste heat energy recovery device using a shape memory alloy includes a heat transfer material that transfers heat from a heat source, an energy generation module that generates energy by receiving heat from the heat transfer material, an outlet pipe through which the fluid leaked from the energy generation module flows, and an outlet pipe. A waste heat energy recovery device using a shape memory alloy comprising a heat dissipation module for cooling the fluid leaked through, and an inlet pipe through which the fluid flows back into the energy generation module after being cooled by the heat dissipation module, the energy generation module comprising: A hollow is formed for accommodating the fluid heated by the heat transferred by the heat transfer body, and the fluid before heating flows in from one end, and the fluid after heating flows out from the other end. A shape memory alloy spring that expands when the temperature of the fluid in the hollow rises, and the cooled fluid flows into the hollow and contracts when the temperature of the fluid in the hollow decreases, a permanent magnet that advances by the expansion of the shape memory alloy spring, shape memory alloy After the spring is compressed, it includes a bias spring for moving the permanent magnet backward, and an external winding wound on the outside of the tube, in which an induced electromotive force is generated by the forward and backward movement of the permanent magnet.
