Product Description

USING  FOREIGN bimetal disc as temperature sampling element, the water  temperature switch is mounted on the tank temperature sensitive parts,  dynamic collection tank water temperature changes by dish-shaped metal  sheet is deformed at a temperature and temperature transient point  beating the principle role, with the institutions, so that the two contacts  quickly turn on, start the fan, water cooling tank, the engine of the  car to play safe

Principle: transient temperature points beating
       It  consists of two tranches of wax texture and temperature element contact  action mechanism driving the composition, the use of paraffin when  heated from a solid into a liquid volume suddenly increases to move  fader control opening and closing of the contacts. With  coolant temperature, the wax begins to expand, while the overwhelming  tension spring frame by pushing the plunger rubber sealing film. When the cooling water temperature rose to 95 ℃, low contact is  closed, the radiator fan motor power, low speed to 1600 r / min of.
      When  the cooling water temperature continues to rise to 105 ℃ when, due to  continued expansion of the paraffin leaving the high-speed contact is  closed, the radiator fan motor in high speed 2400r / min, in order to  increase the cooling intensity. When the cooling water temperature drops, paraffin volume contraction,  putting retraction leaving the contact is opened, the realization of  the radiator fan motor control in the role of the contact tension.
