    Abstract: A heating device and a temperature control device are provided. The heating device includes a heating element, and a heat conducting film disposed on the surface of the heating element, wherein the heat conducting film has a surface area that is larger than the contact area between the heat conducting film and the heating element. The heat conducting film is used for uniformly conducting heat generated by the heating element. Therefore, the existing non-uniform heating and slow heat dissipation problems for the heating element having a large surface area can be solved. Furthermore, because the metallic heat conducting film has good heat conduction, the heat can be quickly spread over a larger area to prevent localized overheating and damage to the heating element itself or the electrical product.

    Abstract: A resistive heating element 30 has a higher molybdenum carbide content in a central portion 35 than in a peripheral portion 34. Since molybdenum carbides have a low temperature coefficient of resistance compared to molybdenum, the amount of heat generated in the central portion 35 of the resistive heating element 30 does not increase as much as in the peripheral portion 34 even when the temperature is increased, and the increase in difference in temperature between the peripheral portion 34 and the central portion 35 can be suppressed.

    Abstract: A system includes a first heater located at the leading edge of a gas turbine structural member, a second heater located aft of the first heater, and a third heater located aft of the second heater. The first, second and third heaters are electrically-powered to prevent icing of the gas turbine structural member. Each of the heaters has a Watt density, and the Watt densities of the heaters differ from one another as a function of a magnitude of a cooling coefficient for airflow passing the vicinity of each heater.

  • Publication number: 20110253704
    Abstract: [Problem] When abnormal conditions are encountered, for example, when the flow of a large current takes place immediately after the start-up of operation, due to a difference in instantaneous thermal expansion between a heat-generator and a base body, a gap may develop between them or cracks may appear in the base body. [Solution] A ceramic heater (10) is constructed by embedding a heat-generator (2) in a base body (1) made of ceramics. The heat-generator (2) has a recess (5) in a surface thereof, the ceramics being inside the recess (5). Even if a great thermal stress is developed due to a difference in thermal expansion between the heat-generator (2) and the base body (1), by the recess (5) inside which the ceramics that forms the base body (1) exists, occurrence of a gap between the heat-generator (2) and the base body (1), as well as appearance of cracks in the base body (1), can be prevented even in the direction of the length of the heat-generator (2) in which the thermal stress is applied heavily.

The panel contains a number of layers including first, second and third electrically insulating layers. A first electrically conductive resistive layer (heater layer) is sandwiched between the first and second insulating layers. A second electrically conductive resistive layer (resistive neutral plane layer) is sandwiched between the second and third insulating layers. The heater layer has a neutral electrical connection and a live electrical connection. The neutral and live electrical connections are electrically connected to each other at the panel only by electrically resistive material of the heater layer extending between the neutral and live electrical connections. The resistive neutral plane layer has a neutral electrical connection electrically connected with the neutral connection of the heater layer.

  • Patent number: 8035064
    Abstract: The product is basically a heating blanket that is adapted in size to fit around a canister of refrigerant used to recharge heat pumps, air conditioners and refrigerators in a commercial or home setting. The blanket has a heating element within it which heats the canister when placed around the canister. From one corner of the blanket is an electrical cord which runs to a small control unit and then to a plug that fits a common 110 voltage household outlet. The control unit consists of a fitting that is designed to be attached to the valve on the top of the refrigerant canister. This fitting is attached to a pressure sensitive valve that sense the pressure of the refrigerant that passes through the valve. This pressure sensitive valve turns off the flow of electric to the blanket when the gas hits a certain pressure.
