초록 ▼

According to the present invention, in a cooling water circuit having a water-cooled internal combustion engine for a vehicle, a pump for pumping cooling water, and a heat-accumulating tank for thermally insulating and storing the cooling water having flowed out of the engine, at least one of an inflow cooling water passage for introducing the cooling water having flowed out of the engine into the heat-accumulating tank and an outflow cooling water passage for introducing the cooling water having flowed out of the heat-accumulating tank into the engine is closed while the engine is stopped. In this way, the convection between the cooling water in the heat-accumulating tank and the cooling water in the other portions than the heat-accumulating tank can be prevented, and the heat insulating capacity of the heat-accumulating tank can be improved.

[ What is claimed is:] [1.] A cooling water circuit system for a water-cooled internal combustion engine for a vehicle, comprising:a pump for pumping cooling water circulating through said engine;a heat-accumulating tank for thermally insulating and storing the cooling water having flowed out of said engine therein;a heater core disposed at a downstream side of said heat-accumulating tank, for performing heat-exchange between the cooling water having flowed out of said heat-accumulating tank and air to be blown into a passenger compartment;an oil heat exchanger disposed at a downstream side of said heater core, for performing heat-exchange between the cooling water having flowed out of said heat-accumulating tank and at least one of lubricating oil of said engine and hydraulic oil of a transmission of said engine;means for forming a bypass water passage for introducing the cooling water at an upstream side of said heat-accumulating tank into an inflow side of said oil heat exchanger while bypassing said heater core;a flow control valve for controlling an amount of the cooling water flowing in said bypass water passage; wherein,said flow control valve closes said bypass water passage during a warm-up operation of said engine and opens said bypass water passage after the warm-up operation of said engine is finished, andsaid flow control valve increases the amount of the cooling water flowing into said bypass water passage according to an increase of the amount of the cooling water flowing from said engine toward said heat-accumulating tank.
