摘要： To control fluctuation of blown air temperature of a heat exchanger to a small value without adding a movable mechanism such as a variable restricting valve, a heat exchanger for heating air by exchanging heat between hot water supplied from a water-cooling type engine and air, a flow control valve for controlling a hot water flow amount to the heat exchanger and a bypass circuit for allowing hot water to flow while bypassing the heat exchanger are provided. A pressure-responsive valve is provided on the bypass circuit and an opening degree of the bypass circuit corresponding to a pressure rise of the hot water is increased. The flow of returning hot water from the heat exchanger is blocked by the flow of the bypass side hot water at a merging portion where the bypass side hot water discharged from the pressure-responsive valve merges with the returning hot water discharged from the heat exchanger.

摘要： An electric heat emitter is disposed at a predetermined position in a heat exchanging core portion having a plurality of tubes and corrugated fins. The electric heat emitter includes a positive electrode plate and a negative electrode plate which are insulated from the heat exchanging core portion. An electric wiring cover made of resin having a positive electrode wiring member and a negative electrode wiring member is attached to an outlet tank of the heat exchanger. The positive and negative electrode plates connect to the positive and negative electrode wiring members respectively. Thus, the electric current is supplied to the electric heat emitter through an electric circuit insulated from the heat exchanger, thereby preventing metal parts of the heat exchanger from being electrically corroded.

摘要： A flow-quantity control valve controlling hot-water flow to a heat exchanger and a bypass circuit allowing hot water to bypass the heat exchanger are provided along with a pressure-actuated valve in the bypass circuit which is responsive to a pressure increase of hot water from an engine. Inlet-side opening portions, outlet-side opening portions, and a bypass-side opening portion are provided in a control passage of a valve body of the flow-quantity control valve. Main flow of dynamic pressure of hot water sprayed from portions on a small opening-degree side act upon a valve body side of the pressure-actuated valve. Due to this, dynamic pressure of the hot water in a small opening-degree region of the flow-quantity control valve can be effectively used to increase a valve-lift quantity of the pressure-actuated valve, thereby reducing a fluctuation range of blown-air temperature of the heat exchanger. Also, the flow may be bent so that hot-water flow having a high dynamic-pressure component from the hot-water inlet pipe is not applied directly to the valve body of the differential-pressure valve; thus, lift of the differential-pressure valve can be prevented from becoming excessive, and a drop in heat-exchanger blown-air temperature at a predetermined opening-degree position of a flow-quantity control valve can effectively be suppressed.

摘要： A coolant circulation circuit of an internal combustion engine includes a heat accumulation tank having a heat insulating structure and a heater core for heating air for heating a compartment in the vehicle. High temperature coolant is reserved in the heat accumulation tank even when the engine is stopped. An intake air heat exchanger is disposed in the circuit on the downstream side of the heater core, and high temperature coolant can effectively heat the intake air. An engine lubricating oil heat exchanger and a transmission operating oil heat exchanger are arranged in the circuit on the downstream side of the intake air heat exchanger. Intake air, engine lubricating oil and transmission operating oils are suitably heated during warm-up of the engine to thereby improve fuel economy and reduce exhaust gas pollution.
