Provided is a heating device which is capable of smoothening flow of a heat medium while reducing a processing time of a case. A heating device 1 is constituted of a case 2 including therein a flow path 3 through which a heat medium flows, and electric heating wire heaters 4 arranged in the flow path 3 of the case 2 to heat the heat medium. The case 2 is constituted of a first case section 6 and a second case section 7 each of which has at least one opened surface and which are connected to each other in a state where respective openings 6A and 7A are made to abut on each other. The respective case sections 6 and 7 are formed by casting of a metal.

A circulation heater is provided which uses a cast body, having resistance heating elements therein and also having spirally wound Teflon tubing wrapped about the heater body. The heater body is formed of cast aluminum or other suitable cast material and after casting is machined to form at least one spiral channel for receiving the heater tube therein. The heater tube is pressed into the tubing channel as the heater tube is progressively wound spirally about the heater body. The channel is formed with an undercut profile wherein the channel is undercut to form a narrower mouth which allows the heater tube to be compressed and then snapped into the channel. The profile of this channel insures direct contact between the tubing and the channel wall over greater than 180 degrees or more than one half of the tube circumference to increase the area of surface contact between the heater tube and channel surface.

A boiler tube clamp including a first portion having a first substantially U-shaped midsection with a first inner surface configured for receiving and pressing against one side of a boiler tube, a first hinge member arranged on one end of the first midsection, and a threaded bolt hingedly attached to the other end of the first midsection, and a second portion having a second substantially U-shaped midsection with a second inner surface configured for receiving and pressing against the other side of the boiler tube. The clamp further includes a second hinge member arranged on one end of the second midsection and hingedly connected to the first hinge member so that the first inner surface and the second inner surface close toward one another. An open slot is arranged at the other end of the second midsection configured for detachably receiving the threaded bolt. A lip extends radially out from an outer surface of the second midsection and arranged adjacent to an edge thereof. A jackscrew extends through the lip for adjusting the distance a boiler tube contained by the clamp extends into a boiler through a boiler header.

The present disclosure relates to an input for production of atomizers and atomizers formed from a sheet of a material, and which may be employed in an aerosol delivery device such as a smoking article. The input may include a carrier and heating elements coupled thereto. The heating elements may include first and second ends and interconnected alternating loops disposed therebetween. The heating elements may be oriented parallel to a longitudinal axis of the carrier, or perpendicular thereto. The heating elements may be coupled to a liquid transport element by bending the interconnected loops at least partially around the liquid transport element. The ends of the heating element may be coupled to heater terminals. A related method for forming atomizers is also provided.
