PURPOSE: A temperature-sensing water pump is provided to improve the fuel efficiency of vehicles with preventing an engine from becoming overheated by adjusting the angle of a blade and the supply amount of coolants according to the temperature of the coolants. CONSTITUTION: A temperature-sensing water pump comprises a rotary shaft(10), and an impeller(20). The rotary shaft is rotated by the driving force of an engine. The impeller supplies coolants to the engine by the rotation force of the rotary shaft. The impeller controls the supply amount of the coolants by adjusting the angle of a blade according to the temperature of the coolants. |
