Proportional Micro-Valve With Thermal Feedback

Номер: US20120012299A1
Автор: Randall N. Avery
Принадлежит: Industrial Idea Partners Inc

A proportional micro-valve for regulating the temperature of an electronic component comprising a cooling subsystem associated with each thermal zone of the electronic component, a cooling circuit carries cooling fluid to a heat exchanger associated with each thermal zone, the flow of which is controlled by a valve element, which is in turn controlled by a sensing circuit which reacts to the temperature of the underlying thermal zone to proportionally increase or decrease the rate of cooling fluid flowing through the heat exchanger based upon the temperature of the thermal zone. Cooling fluid substantially continuously flows through the sensing circuit, regardless of whether the valve element is open or closed. The sensing circuit provides feedback to a temperature-responsive mechanical amplifier for opening and closing the valve element.

Energy-Optimal Control Decisions for Systems

Номер: US20120101648A1
Автор: Clifford C. Federspiel, Jerry Chin
Принадлежит: Vigilent Corp

Methods, systems, and apparatuses are provided for controlling an environmental maintenance system that includes a plurality of sensors and a plurality of actuators. The operation levels of the actuators can be determined by optimizing a penalty function. As part of the penalty function, the sensor values can be compared to reference values. The optimized values of the operation levels can account for energy use of actuators at various operation levels and predicted differences of the sensor values relative to the reference values at various operation levels. The predicted difference can be determined using a transfer model. An accuracy of the transfer model can be determined by comparing predicted values to measured values. This accuracy can be used in determining new operational levels from an output of the transfer model (e.g., attenuating the output of the transfer model based on the accuracy).

Exhaust heat from such devices is utilized as intake cooling air for the gas-fueled power sources, thereby excluding them from cooling capacity requirements. The gas piping delivering gas to gas-fueled power sources is positioned so as to be within hot aisles comprising exhaust heat. The gas piping is located up high for lighter than air gasses and near the floor for heavier than air gasses, with leak detection located nearby. Additionally, gas piping is externally coated with material that visually indicates a leak. By locating gas piping in the hot aisle, exhausted heat increases temperature and, thereby, pressure of the gas, resulting in more efficient gas distribution through the piping and preventing valve freezing. Furthermore, the gas piping is located after potential ignition sources in the airstream. 1.

Pressure balanced thermal actuator

A pressure balanced thermal actuator includes a flow housing having an inlet and an outlet, with the flow housing being affixed at opposing ends to two bellows housings, each of which contains a bellows. An actuation rod is operably coupled to each bellows and contains a fluid passage therewithin. When the temperature of the area surrounding the actuator increases, the pressure inside the bellows housings increases, and exerts a force on the bellows therein, compressing it. As a result, the actuation rod moves from a first position to a second position to align the fluid passage with the inlet and the outlet, enabling the controlled passage of a first fluid from the inlet, and through the fluid passage, to the outlet, to reduce the temperature of the area surrounding the valve assembly. The actuator is unaffected by changes in the ambient pressure, by working equally on two opposing bellows areas.

A thermostat management system facilitates an automatic pairing of a thermostat with a thermostat communication account. The thermostat management system receives a public network address associated with a computer device on a private network accessing the thermostat management account. The system retrieves the thermostat metadata including a public network address associated with a registration of the thermostat with the thermostat management system. The public network address registered with the thermostat metadata is provided by a router on the private network and therefore should match the public network address used by computer devices on the private network. The thermostat management account is paired with the thermostat if the thermostat has the same public network address as the computer device accessing the thermostat management account. Pairing the thermostat management account to the thermostat allows the thermostat management account to communicate with the thermostat over the public network through the thermostat management system.

Electrical and electromechanical devices often require maintaining a specific temperature, or a narrow range or temperatures, during operation. An assembly regulates the temperature of a device by providing a variable thermal resistance between the device and a heatsink. The device can be mounted to a base having a high thermal resistance, the base thermally isolating the device from the heatsink. At low environmental temperatures, the base enables the device to rise to its operating temperature as a result of the device's waste heat, and with no or minimal use of a heater. As the environmental temperature increases, a working fluid, having a low thermal resistance, undergoes thermal expansion to fill a portion of a volume in the base between the device and the heat sink, lowering the thermal resistance between the device and the heatsink to maintain the device at the required operating temperature. 1.

A thermostat for controlling the flow of a coolant into a radiator and a bypass circuit is provided. When the bypass circuit is to be closed, the thermostat displaces a shaft that is operably attached to a bypass plate. When in the closed position, the bypass plate is configured to engage a top wall of the bypass circuit so as to prevent the flow of coolant into the bypass circuit. To minimize the formation of a water pressure pulses generated by the closing of the bypass circuit, only a portion of the bypass plate initially contacts the top wall. Such limited contact allows for the restriction of the flow of coolant into the bypass circuit, and interrupts the even flow of coolant around the bypass plate. Such restriction and/or interruption allows for the gradual closing of the bypass circuit, which minimizes the associated water hammer effect. 1. A thermostat for controlling the flow of a coolant into a radiator and a bypass circuit , the thermostat comprising:a housing having a shaft and a spring, the shaft configured to extend away from the housing from an open position to a closed position as a temperature of the thermostat increases;a bypass plate operably secured to the shaft, the bypass plate having an outer surface and a central longitudinal axis, the outer surface configured to abut against a top wall of the bypass circuit to prevent the flow of coolant into an opening of the bypass circuit when the shaft is in the closed position, the central longitudinal axis of the bypass plate not being parallel to a central longitudinal axis of the housing as the shaft is displaced from the open position and toward the closed position.2.
