The Application of Ni-Ti Shape Memory Alloy to the Cooling System of Armored Vehicles

To reduce the thermal losses of water and air cooling systems and improve the performance of the coldstart of armored vehicles in winter, a thermostat double driven by paraffin and memory alloy and an intelligent temperature-controlled shutter have been invented and designed. The design limitation of the cooling system of armored vehicles can be mended. Their structure, principle, and operation characteristics have been discussed and the design method of SMA spring has been put forward as well. Their application can save the start time and the fight preparation time of armored vehicles greatly and is significant to improve the tactical performance of the northern armored vehicles in winter.
