Working Principle
1.The working principle of the snap action bimetallic thermostat is that the temperature sensitive element bimetal disc is pre-formed at a certain temperature, when the ambient temperature changes, the bending degree of the disc will change. When bending to a certain degree, the circuit is switched on (or disconnected), so that the cooling (or heating) equipment works.
2.Thermal bimetal is composed of two or more kinds of different expansion coefficient of metal or alloy along the entire contact surface firmly combined together with the shape changes with temperature composite functional materials.
3.In the thermal bimetallic component alloy, the component alloy layer with a higher expansion coefficient is generally called the active layer or high expansion layer (HES). The component alloy layer with low expansion coefficient is called passive layer or low expansion layer (LES). Adding an intermediate layer of different thickness between the active layer and the passive layer as a conductive layer, generally including pure Ni, pure Cu and zirconium copper, etc., mainly used to control the resistivity of the thermal bimetal can obtain a series of resistive thermal bimetals with basically the same thermal sensitive properties and different resistivity.
