  • Patent number: 11199124
    Abstract: A cooling apparatus for an internal combustion engine includes a pump, a radiator, a flow rate adjustment valve, a bypass passage, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a valve member biasing component that biases the valve member in a valve-closing direction in which the open degree decreases. The valve member rotates in a valve-opening direction in which the open degree increases when a pressure difference increases between positions upstream and downstream of the valve member in a flow direction of coolant in the circulation circuit and rotate in the valve-closing direction when the pressure difference decreases. The controller increases the pump discharge amount as a target radiator flow rate that is a target of an amount of coolant passing through the radiator increases.

The heat exchanger exchanges heat between the refrigerant and the hot fluid. The heater warms the hot fluid having undergone heat exchange. The cooling flow passage cools an electrical component. The communication flow passage parallelly connects the hot fluid and electrical component flow passages. The valve allows hot fluid to flow into the cooling flow passage when the hot fluid has a high temperature.

  • Patent number: 9347371
    Abstract: The instant invention is to a new fuel system, which will allow operation of large scale electrical power generating facilities at a fraction of the cost of coal or natural gas fueled facilities and will not produce significant heat, exhaust emission gases, or particulate pollution. Because of the nature of the chemical reaction exploited in the system, it is denominated an instant entropy system (“IES”). The fuel used by the inventive IES produces gas expansion, but not from an oxidation/combustion reaction, and it does not produce oxidative exothermic heat. The IES utilizes a material first developed in the early part of the twentieth century—triacetone triperoxide (TAP).

    Abstract: An electronic control unit (12) calculates the heat receiving quantity of a thermo wax to estimate the temperature of the thermo wax on the basis of the calculated heat receiving quantity and the heat capacity of the thermo wax, and controls a heater so that the temperature of the thermo wax reaches a predetermined target value. Further, the electronic control unit (12) changes the value of the heat capacity used to estimate the temperature of the thermo wax depending on the variation of the estimated temperature of the thermo wax across the phase transition point of the thermo wax so as to preferably control a switching valve which is operated by heating the thermo wax.

  • Patent number: 9020740
    Abstract: A system includes a sump, a pump having a steady-state speed, a fluid component that receives the fluid from the fluid pump, and a controller. The controller detects a soak condition of the system in which the pump load is low as fluid is moved into vacated fluid passages. The steady-state speed of the pump is temporarily increased by adding a calibrated overspeed value to the steady-state speed, for a calibrated duration. The controller reduces the pump speed to the steady-state speed after the calibrated duration has elapsed. A method includes detecting the soak condition and temporarily increasing the steady-state speed via the controller by adding the calibrated overspeed value to the steady-state speed, for a calibrated duration, when the soak condition is detected. A control system includes a processor and storage medium having instructions embodying the method, with detection of the soak condition provided via measurement of fluid temperature.

  • Patent number: 8991338
    Abstract: A vehicle includes an engine capable of being intermittently stopped after it is started; a water pump for circulating cooling water, and an ECU. When the cooling water has low temperature the ECU controls the water pump to limit the flow rate of the cooling water to be smaller than when the cooling water has high temperature. When the cooling water has a limited flow rate the ECU sets lower a threshold value of the cooling water's temperature for permitting intermittently stopping the engine than when the cooling water does not have a limited flow rate. When the cooling water has a limited flow rate the engine can nonetheless be intermittently stopped at an appropriate time.

    Abstract: A heat storage device keeps engine coolant hot during operating pauses of the engine allowing quick heating during a cold start of the engine. The capacity of the heat storage device for coolant is twice as large as the capacity for coolant of the coolant circulation system and the engine. An inflow line, an outflow line and a ventilation line pass through the bottom of the heat storage device and are heat insulated on the inside of the heat storage device. Hot coolant from the heat storage device is transferred in two portions into the cold engine. The second portion is transferred when the rising temperature of the metal motor mass has come close to the falling temperature of the first portion of coolant that was circulating in the engine. The heat storage device includes outer and inner containers with a high vacuum in the insulating space between the containers.

  • Patent number: 8948946
    Abstract: A thermal system includes fluid-cooled devices, a controller, and a thermal loop or loops each having a cooling actuator and fluid passages. The controller executes device-specific control logic to arbitrate between cooling requests having different relative priorities. The controller receives raw speed requests and noise, vibration, and harshness (NVH) limits for each device, and processes the raw speed requests and NVH limits to determine a relative cooling priority for each device. The controller outputs a speed command to the actuator(s) for each thermal loop in order to cool the devices at a level required by the device having the highest relative cooling priority. A vehicle includes a traction motor, a transmission that is selectively connected to the traction motor, fluid-cooled devices each in electrical communication with the motor, and a controller configured to execute the arbitration method noted above.
