The heater includes an insulating material that is coordinated with the internal diameter of a metal jacket (2). The hot wire ends (9, 10) are provided with terminals projecting from the same end of the metal jacket (2). The hot wire coils (11, 12) are electrically connected to one another in the area of an end edge of the carrier wall (14). This edge is located in the closed end area of the metal jacket (2) and the coils are guided by spacers (45) distributed at the longitudinal edges of the carrier wall (14). At least the terminal-side end of the dimensionally stable carrier wall (14) is provided with an attached coil holder (15, 15/1), to which the hot wire ends (9, 10) are fastened under tensile stress. This keeps the windings of the hot wire coil (13) spaced apart from each other.

  • Patent number: 8395093
    Abstract: The preferred embodiment utilizes metal coated high strain fabric reinforcement including but not limited to fiberglass, cotton fiber, or other materials that can undergo deformation, and various resin or elastomer compounds to create a conductive polymer whose resistivity and resistance remain essentially constant under a strain of approximately 0-150% or more. Additionally, the preferred embodiment utilizes a method of imprinting, depositing, etching, or embossing a design or pattern of conductive metal on fabric used in composites. The use of designs of conductive metals wrapped around a deformable core and the unique features of elastomeric polymers allows for their use as a flexible circuit board, formable heaters, and other various uses.

  • Patent number: 8395095
    Abstract: An electrothermal transfer device includes a substrate, a plurality of electrothermal components and a heating circuit. The electrothermal components are disposed on a surface of the substrate and arranged in a pattern. The heating circuit is electrically connected to the electrothermal components. In an electrothermal transfer method, at first, a transfer substrate is disposed on a workpiece substrate. Then, the electrothermal transfer device is disposed on the transfer substrate so that the electrothermal components contact with the transfer substrate. Thereafter, the heating circuit is used to heat the electrothermal transfer components so that the transfer substrate is heated to be transferred to the workpiece substrate. The electrothermal transfer device and the electrothermal transfer method can reduce cost.

  • Patent number: 8395094
    Abstract: A heating structure includes an opening that surrounds a heating element and a heat transfer element. Each heat transfer element is disposed between an exterior surface of the heating element and an interior surface of the opening. A clamping mechanism is used to clamp each heating element against a heat transfer element. Each heat transfer element partially surrounds a heating element and is configured to create at least two elongated and spatially separate contact regions along a length of the heating element. The at least two contact regions form a line of contact between the heating element and the interior surface of the opening when the heating element is clamped against the heat transfer element. The at least two contact regions allow the heating element to transfer heat to the opening and to the tooling device. The clamping mechanism may also be used to transfer heat to the tooling device.

  • Patent number: 8383997
    Abstract: A double-sidedly bondable planar element which has an electrical contacting layer via which it is self-regulatingly intrinsically heatable and at the same time has a high flexibility. The particular features of this planar element are that the planar element in the storage condition is adhesive on one side only, and is therefore particularly easy to handle, and that, on bonding, the adhesive passes through cutouts in the contacting layer, and the planar element thus becomes double-sidedly bondable. The invention further provides a method for the bonding of this planar element, including as a key step the passage of the adhesive through the cutouts in the contacting layer, thus turning a single-sidedly adhesive planar element into a double-sidedly adhesive planar element.
