  • Patent number: 8541721
    Abstract: An improved solid heat transfer element composed of an elongate member having a generally cylindrical surface with male vortex generating protrusions is provided. The vortex generating protrusions, which may be referred to as “turbulators,” provide improved heat transfer by convection to a flow of air transverse to the elongate members without substantially increasing the pressure drop in the flow of air passing over the members. Advantageously, a plurality of the heat transfer elements, or of straight portions of a single serpentine heat transfer element, may be arranged in an aligned or staggered array of elements or straight portions. Many advantageous profile shapes of the element and vortex generators are provided, including aerodynamic profile shapes that are symmetrical with respect to a fluid flow to provide low drag and pressure drop. Heat in the element may be generated by means of electrical resistance or absorption of radiation.

    Abstract: The heating device mainly contains a dual-core heat cable and a control circuit. The dual-core heating cable mainly contains a core, a heating wire winding spirally around the core, a NTC (negative-temperature-coefficient) layer wrapping around the core and the heating wire, a PTC heating wire winding spirally around the NTC layer, and an insulating layer wrapping around the NTC layer and the PTC heating wire. The control circuit monitors the PTC heating wire's current for constant temperature control, and the leakage current through The NTC layer as a second over-temperature protection. As such, the heating device has a superior constant temperature effect and avoids the problem of burning down the heating cable. The heating device therefore has a longer operational life span.

  • Patent number: 7592572
    Abstract: A cartridge heater, especially a compressed cartridge heater (1) has at least one heating coil (8, 9), which is arranged exposed in a metallic tubular body (2) and is embedded in a granulated insulating material. The ends of heating coil portions (8, 9) are provided with terminals (7) projecting from the tubular body (2). To make it possible to manufacture such a cartridge heater with minimal effort in terms of labor and material, a flat insulating plate (10) coordinated in its width with the internal diameter of the tubular body (2) is provided as the carrier. The heating coils (8, 9) extend along the two flat sides of the insulating plate (10) and the two heating coils (8, 9) are connected to one another by a coil section (12, 12?), which is led around a deflecting edge (27) of the insulating plate (10).

  • Publication number: 20090223946
    Abstract: A flexible thermal radiator made by using two comb powering conductors to power the electrical heating element. The electrical current passes from one powering conductor to the other through the electrical heating element. The comb powering conductors provide an even distribution of currents throughout the structure and hence maintain a uniform current density that results in uniform temperature distribution of the structure avoiding hot-spots.

  • Publication number: 20090223947
    Abstract: The present invention relates to a ceramic heating element, a ceramic heating element with terminals, and a ceramic heating tube, which consists of a mixture of china clay powder in a volume of 25% to 75% and conductive graphite powder in a volume of 25% to 75%, a vitreous insulation layer, and an enamel layer. The mixture is sintered to form the vitreous insulation layer and the enamel layer from inside to outside. Inside the vitreous insulation layer is the mixture of the china clay powder and the conductive graphite powder which are not vitrified to form a conductive layer. The ceramic heating element has two ends connected with a first terminal and a second terminal to form a ceramic heating element having terminal or a ceramic heating tube for heating.

  • Publication number: 20090039075
    Abstract: A heating element that can maintain a laminator at a predetermined working temperature is disclosed. A low-power heating filaments and a high-power heating filaments are sandwiched between insulators. The high-power heating filaments are shut down once it is heated to a predetermined temperature. The low-power heating filaments are then turned on to maintain a constant temperature. When the temperature drops below a predetermined temperature, the low-power heating filaments are shut down and the high-power heating filaments are turned on to heat up the laminator. The temperature is thus maintained within a predetermined range through such cycles.
