Abstract

PURPOSE:To make it possible to keep the temperature of cooling liquid at a predetermined value by a method wherein the quantity of the cooling liquid passing through a radiator is adjusted. CONSTITUTION:A large-diametered valve 16 and a small-diametered valve 18 are provided between the cooling liquid inlet port 12 of a radiator 10 and the main body 14 thereof in parallel relationship with each other. In this case, the temperature sensor 16a of the large-dimaetered valve 16 is positioned on the side of the inlet 12 and the temperature sensor 18a of the small-diametered valve 18 is positioned at the junction of a bypass pipe 22 and an outlet 20. When an engine 24 is started in a condition in which the temperature of the cooling liquid is low, the cooling liquid is heated while it circulates through the inlet 12 the bypass pipe 22 the outlet 20 in that order because the valves 16 and 18 are closed, so that the temperatures around the temperature sensors 16a and 18a become equal. Next, when the temperature of the cooling liquid rises, the sensor 18a operates earlier than the sensor 16a because of the smallness of its heat capacity and so the valve 18 is opened to allow the cooling liquid to flow into the body 14 of the radiator. Thus, when a large amount of heat generates and the quantity of the cooling liquid passing through the valve 18 becomes insufficient to meat the heat, the valve 16 is opened to allow a large quantity of cooling water to flow into the body 14 of the radiator.
