A heater assembly with a pre-encapsulated heating element and a method of producing the pre-encapsulated heating element are provided. The heater assembly can include a channel defining an interior space and a pre-encapsulated heating element. The pre-encapsulated heating element can include a resistive heating element having a pre-encapsulated portion that is surrounded by a block of potting compound. The pre-encapsulated portion can be received with the interior space of the channel.

A method for forming a heater on a substrate includes feeding a heater wire into a heating zone, the heater wire being in contact with a dielectric material within the heating zone, and coaxially co-extruding the heater wire and the dielectric material from the heating zone through a nozzle and onto a substrate such that the heater wire and the dielectric material form a heater for heating the substrate.

A method of manufacturing a heater for an aerosol-generating device is provided, the method including: forming a heater body including a heater body frame and a heating element, the heater body defining at least a portion of a boundary of a heating chamber configured to receive an aerosol-generating article such that the heating element is configured to heat the heating chamber, at least part of the heater body frame being manufactured by additive manufacturing. A method of manufacturing an aerosol-generating device; and a heater; and an aerosol-generating device are also provided.

A liner for a crisp plate includes ceramic nanoparticles and a polymer material combined with the ceramic nanoparticles to provide a mixture. A network of carbon nanotubes is embedded within the mixture to form a composite matrix, wherein the carbon nanotubes are unidirectionally aligned within the composite matrix.

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.

An induction cooking system includes a first container that receives first contents and a second container sized to fit within the first container. The second container is composed of a ferromagnetic material such that the second container is heated in response to received electromagnetic radiation. An exterior surface of the second container is in contact with the first contents of the first container, and an interior surface of the second container is in contact with second contents placed within the second container.

In manufacturing an electrothermal heater mat, there is provided a preform which comprises a laminated stack of dielectric layers which are made of thermoplastic material and include a central layer or group of layers which include(s) reinforcement and first and second outer groups of layers which do not include reinforcement. The preform includes a heater element and the preform has a first configuration. The preform is then heated to a temperature (e.g. 180° C.) between the glass-transition temperature of the thermoplastic material and the melting point of the thermoplastic material, and the heated preform is formed into a second configuration which is different to the first configuration so as to produce the heater mat.

A method for forming a heater on a substrate includes feeding a heater wire into a heating zone, the heater wire being in contact with a dielectric material within the heating zone, and coaxially co-extruding the heater wire and the dielectric material from the heating zone through a nozzle and onto a substrate such that the heater wire and the dielectric material form a heater for heating the substrate.

An air transfer apparatus being made as a monolithic or an integral structure or enclosure. The air transfer apparatus is made from a non-porous material and is made from any of the manufacturing methods of molding, injection molding, gas assisted injection molding, liquid/water assisted injection molding, blow molding, extruding, electrofusion or 3-D printing. The air transfer apparatus can be any of a cooling tower, a swamp cooler or a cooling Indirect Direct Evaporative Cooler. The air transfer apparatus has at least one integral cavity manufactured therein and at least one heat exchanger pad can be attached to the air transfer apparatus or made integral with the air transfer apparatus.

Provided is a heater for a ciga-like electronic cigarette with a heat transfer efficiency improved by strengthening a bonding force between a cigarette support portion and a heater portion by thermally pressing and bonding the cigarette support portion and the heater portion together using a heat-dissipating adhesive layer with a heat-dissipating filler added to a high-heat-resistant thermoplastic polyimide resin, and a method of manufacturing the same.
