A method for assembling an induction heating device includes the steps of interposing at least one ferrite bar between a coil assembly and a support plate, and snap engaging a central polymeric fastening element on the support plate. At least one end of the ferrite bar is inserted in a radial seat of the central polymeric fastening element. The coil assembly is snap engaged with the central polymeric fastening element in order to sandwich the ferrite bars between the support plate and the coil assembly.

The present invention relates to a heating plate for an electric hair iron and a method for manufacturing the same. More specifically, the present invention relates to a heating plate for an electric hair iron having a soft synthetic resin inserted therein, wherein an aluminum heating plate having a plurality of grooves formed in a longitudinal direction on the front surface is ejected and the soft synthetic resin is inserted into the front surface and both sides of the aluminum heating plate which is in a state of being inserted into a mold such that part of the soft synthetic resin is insertedly integrated into the grooves. The soft synthetic resin is injected from the rear of the aluminum heating plate to the front surface thereof when injecting the soft synthetic resin such that a uniformly even soft synthetic resin layer is formed without generation of bubbles on the front surface by injecting. Accordingly, a hollow through-hole is formed between the grooves of the aluminum heating plate such that heat is uniformly transferred, and a ceramic coating layer is formed inside the groove such that heat is evenly transferred across the soft synthetic resin layer.

A method for the production of a heat-generating element includes placing in which at least two electrical conductor elements, provided with through holes, onto a film provided with an adhesive mass, pressing the conductor elements against the films such that the mass is forced into the through holes. At least one PTC element is subsequently placed onto one of the conductor elements, and then the other of the conductor elements, together with the film adhering thereto, is placed opposite to the one of the conductor elements onto the PTC element. The invention further relates to a heat-generating element with a PTC element and electrical conductor elements connected thereto in an electrically conductive manner for energizing the PTC element with a different polarity and an electrical insulation that is provided on the outer side thereof with a film and an adhesive mass applied thereto. At least one of the conductor elements is provided with through holes and the mass is at least in part contained in the plane of the conductor element.

A method of constructing a heating chamber for an aerosol generation device includes providing a side wall of the heating chamber, providing a heater, and arranging the heater to be in thermal contact with the side wall of the heating chamber. The method may also include attaching a heat shrink layer to the outward facing side of the heater, and heating the heat shrink layer to a temperature such that the heat shrink layer contracts to compress the heater against the side wall. The heating chamber for the aerosol generation device includes a side wall defining an interior volume of the heating chamber, and a heater in thermal contact with the side wall, as well as a heat shrink layer under tension, compressing the heater against an outwardly facing surface of the side wall.

An electric heating pad with electrosurgical grounding comprising a heated underbody support, heated mattress or heated mattress overlay. In an illustrative embodiment the heating pad with electrosurgical grounding may include a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges and a flexible sheet-like grounding electrode including an upper edge, a lower edge, and at least two side edges. A shell covering the heating element and grounding electrode and comprising at least two sheets (e.g., may be one sheet of material folded over to form two sheets) of flexible material, and a weld coupling the two sheets of flexible material together about the edges of the heating element and grounding electrode, wherein the weld is one of a RF weld, ultrasonic weld, or a heat bond, wherein the two sheets comprise PVC or urethane.

An injection molded housing includes a first piece, a second piece, and a wall defined by the first piece removably joined to the second piece by a joint at abutting surfaces of the first piece and the second piece. A central catch is integrally molded with the first piece, protruding from the wall. A latch is integrally molded with the second piece, and connected to the second piece first and second living hinges. A half-knuckle is integrally molded with the second piece, protruding from the wall. A hinge pin is fixedly attached to the latch. The latch is bendable at the living hinges to align the hinge pin with the half-knuckle. The latch is rotatable about the hinge pin to engage the central catch and selectably prevent the first piece from being disengaged from the second piece.

A thermal conductive strip with a power supply terminal includes: a carbon fiber unit including a carbon fiber connecting end; a plastic envelope which encapsulates the carbon fiber unit and has a length smaller than a length of the carbon fiber connecting end, and further includes a broken portion which covers a part of the carbon fiber connecting end; and the power supply terminal sleeved onto the broken portion and the carbon fiber connecting end, and including a clamping section for clamping the broken portion, and an electrically conductive section for contacting the carbon fiber connecting end. The power supply terminal is partially clamped on the plastic envelope and partially eclectically connected to the carbon fiber, which improves the yield rate and the bending durability of the thermal conductive strip of the present invention.

Proposed is a method of manufacturing a PTC heating element, the method including: (a) preparing a mixed powder of a polymer powder and a carbon nanotube-containing powder, (b) forming the mixed powder into a pellet-shaped body, and (c) extruding the pellet-shaped body to produce a wire-type heating element. A PTC heating element manufactured by the method is also proposed. The PTC heating element manufactured by the method has better thermal conductivity than existing PTC heating elements, so that the PTC heating element exhibits a quick temperature rise within a short time, resulting in a reduction in power consumption. In particular, when the PTC heating element is used as a heating element for car seat heaters and steering wheel heaters in electric vehicles, battery consumption may be dramatically reduced, contributing to an increase in the driving mileage of the electric vehicles.

A composite sandwich panel includes a perforated heater element in the middle of two structural plies, attached by a resin infiltrating perforations on the surface of the heater element. The heater element in the sandwich panel can withstand greater shear stress than non-perforated elements. The composite sandwich panel includes support layers such as honeycomb or foam.
