A mounting structure for a heat accumulation tank is provided with an elastic member that wraps around a tank main body, and a heat accumulation tank mounting member which wraps around the outer peripheral surface of the elastic member and holds the tank main body by being tightened in the circumferential direction, and which attaches to a receiving member. The elastic member is a molded part. The length of the elastic member is shorter than length of the circumference of the outer peripheral surface of the tank main body. The heat accumulation tank mounting member includes a shift inhibiting portion which inhibits an upward shift of the tank main body. The outside diameter of the tank main body becomes increasingly wider in the upward direction.

Mounting structure and method for heat accumulation tank

A double-layer vacuum container includes: an inner container having a bridging member supported by an outer container in a bridging manner; the outer container through which the bridging member extending from the inner container is externally exposed; and a cover member for externally covering the portion of the outer container through which the bridging member is exposed and for sealing a space inside the cover member and a space between the inner container and the outer container in a vacuum state between the cover member and the outer container. With such a structure of the double-layer vacuum container, the inner container other than a lip is supported by the outer container with a good heat retaining property to prevent the displacement or damage of the inner container.

Heat storage tank

A cooling system comprising a cooling water circuit in which cooling water of an engine circulates in a radiator , a hot water circuit in which hot water circulates in a heater core , an air mixing door for adjusting the volume of air which passes through the heater core, a heat storage element provided in a bypass passage for branching hot water into the heat core from the hot water circuit, a flow path selector valve for adjusting the distribution of hot water to the heat storage element and the heater core, and a control unit for controlling the operation of the air mixing door and the flow path selector valve, wherein the control unit controls the flow path selector valve such that the flow rate of hot water to be distributed to the heater core becomes larger than the flow rate of hot water to be distributed to the heat storage element, in the event that the volume of air passing through the heater core is equal to or larger than a predetermined value.

Automotive internal combustion engine cooling system

In a heat storage tank, a discharge port of an introduction passage is covered by a cup-shaped collision member constructed by a shield portion and a guide cover. In addition, a mixture protection plate having plural through holes is disposed in a tank body between the collision member and an inner surface of the tank body. Therefore, a high-speed water stream, upwardly injected from the discharge port, collides with the shield portion, and turns its flow direction by an approximately right angle. Thereafter, the water stream is guided by the guide cover to a lower side of the mixture protection plate. Accordingly, it can prevent water stored in the tank body from being mixed even when the injection water stream has a high speed.

In a heat storage tank, an elbow pipe member defining a water introduction passage is formed by connecting an inlet-side cylinder portion and an outlet-side cylinder portion to have a corner portion. A step portion is disposed in the water introduction passage around a position where center lines of both the cylinder portions are crossed with each other. The step portion has a collision surface that is set to cross with a line parallel to the center line of the inlet-side cylinder portion, so that water introduced from the inlet-side cylinder portion collides with the collision surface of the step portion.

In a water discharge mode (heat storage mode) for discharging low-temperature cooling water from a heat storage tank to a side of a heater core that heats air using cooling water from an engine as a heating source, a cooling water amount discharged from the heat storage tank is made smaller as a necessary heating capacity for heating air becomes larger. For example, as an amount of air flowing through the heater core becomes larger, the cooling water amount discharged from the heat storage tank becomes smaller. Further, as the temperature of the cooling water flowing into the heater core becomes higher, the cooling water amount discharged from the heat storage tank is increased.

Vehicle air conditioner with heat storage tank

In a heat storage tank, first and second valve bodies are disposed to open and close first and second valve ports, respectively. A density of the first valve body is made larger than that of cooling water, and a density of the second valve body is made smaller than that of cooling water. When the dynamic pressure due to cooling water is applied to the first and second valve bodies, the first and second valve ports are opened by the first and second valve bodies. On the other hand, when the dynamic pressure is not applied to the first and second valve bodies, the first valve body closes the first valve port by the weight of the first valve body, and the second valve body closes the second valve port by the buoyancy.

Heat storage tank in cooling water circuit

A combustion type heater of this invention includes fuel distribution means for distributing a fuel to the whole surface of a wick disposed upstream of the wick in a fuel passage. The fuel distribution means comprises fuel distribution grooves and a fuel dispersion plate having a large number of holes bored therein. The fuel distribution means can quickly supply the fuel to the whole surface of the wick. To shorten the heating time of the wick, the heater of the present invention uses a wick heating glow plug outside an ignition glow plug or a planar heater for heating the wick.

Combustion type heater

A heating apparatus for a vehicle includes a pump for circulating cooling water in a cooling water circuit, a heating heat exchanger for heating air blown into a passenger compartment of the vehicle using cooling water as a heating source, and a throttle valve disposed at a discharge side of the pump. In the heating apparatus, when the temperature of cooling water is low and heating capacity for heating the passenger compartment is insufficient, an opening degree of the throttle valve is reduced by a control unit. Therefore, heat is generated from the throttle valve and the pump so that the temperature of cooling water is increased. Thus, heating capacity of the heating apparatus can be improved without using a manual operation.

Heating apparatus for vehicle

A control apparatus and method for controlling an automotive heater apparatus. The heater apparatus includes a coolant circuit for cooling an engine, a coolant circulating through the circuit, a heat generator for transferring heat to the coolant, and a heater core for transferring heat from the coolant. The heat generator houses a viscous fluid and a rotor selectively connected to and disconnected from the engine by a clutch. The clutch connects the engine with the rotor to shear the viscous fluid and generate heat. When the rotating speed of the rotor exceeds a rotor speed limit, which varies in accordance with the detected coolant temperature, the clutch disconnects the rotor of the heat generator from the engine and de-activates the heat generator.

Automotive heater apparatus

An engine cooling apparatus suitable for use in a vehicle shortens engine warm-up time without decreasing the heat-radiation capacity of a radiator. A shroud is disposed between a radiator and a water-cooled engine. A first air passage for blowing air toward the engine and its auxiliaries is formed in the upper side of the shroud, and a second air passage for discharging air having passed through the radiator to outside the engine compartment is formed in the lower side of the shroud. Accordingly, air is prevented from directly striking the engine and from passing around to the upstream side of the radiator through gaps between the walls of the engine compartment and the radiator. Thus the engine warm-up time is shortened without reducing the heat-radiation capacity of the radiator.

Engine cooling apparatus

In a cooling water circuit system, cooling water pumped by a mechanically-driven first water pump circulates in a cooling water circuit, and flows through a radiator and a heater core in parallel in the cooling water circuit. An electrically-driven second water pump is disposed in the cooling water circuit at a position where cooling water to be supplied to the radiator from the first water pump and cooling water to be supplied to the heater core from the first water pump flow together. A check valve is provided in the cooling water circuit in parallel with the second water pump so that cooling water flows in one way from a water suction side of the second water pump toward a discharge side thereof. Thus, when the second water pump is operated, a total amount of cooling water pumped by the first water pump and the second water pump can flow through the radiator and the heater core. As a result, the cooling water circuit system can improve engine-cooling effect in the summer, while improving heating effect of a passenger compartment in the summer.
