A heat exchanger for heating a fluid that exhibits simplified manufacturing, a reduced construction size, and/or an increased heating efficiency. The heat exchanger has at least two distanced tube bodies through which a flow path of the fluid leads. A thin-film resistor is applied on the outer surface of at least one of the tube bodies with an interface made of a thermal interface material located between the thick-film resistor and the next neighboring tube body.

A heating assembly includes: a heating element having a substrate and a heating region, an overlapping region and a conductive region being located on the substrate and sequentially distributed in an axial direction of the substrate and connected, the heating region being provided with a heating circuit which extends to the overlapping region, and the conductive region being provided with a conductive circuit which extends to the overlapping region and is connected with the heating circuit in an overlapping manner or in parallel; and a fixing base, one end of the fixing base fixing the heating element, the fixing base being at least partially in contact with the overlapping region.

A heat treatment device includes: a heating plate that supports and heats a substrate on which a resist film is formed, and the resist film is subjected to an exposure process; a chamber that covers a processing space above the heating plate; a gas ejecting unit that ejects a processing gas from above toward the substrate on the heating plate within the chamber; a gas supply unit that supplies a gas into the chamber from below a surface of the substrate, within the chamber; and an exhaust unit that evacuates inside of the chamber through exhaust holes that are formed above the processing space and open downwards.

The present disclosure describes a personal vaporizer which can detect whether or not a cartridge of the personal vaporizer has been breached. The cartridge includes a conductive shell. The conductive shell can include two or more conductors which are electrically isolated from each-other. Prior to operation, the personal vaporizer can use the two or more conductors to assess whether or not an outer shell of the cartridge has been breached. In some implementations, if it is determined that the cartridge has been breached, the personal vaporizer can shut down, or otherwise fail to operate normally.

An electrically operated aerosol-generating system may include a reservoir configured to hold a liquid aerosol-forming substrate, an atomizer assembly configured to vaporize the liquid aerosol-forming substrate to form an aerosol, and a pump configured to convey the liquid aerosol-forming substrate from the reservoir to the atomizer assembly. The reservoir may include a substantially rigid housing and an inlet valve that is configured to allow air into the reservoir based on a pressure difference between an interior of the housing and an exterior of the housing exceeding a threshold pressure difference. This improves the reliability and efficiency of delivery of liquid to the wick. The system may further include a robust reservoir that is configured to at least partially mitigate liquid leakage between the reservoir interior and the reservoir exterior.

A heater assembly for an aerosol generating device includes a flexible heating element; a temperature sensor; and a flexible dielectric backing film with an adhesive on a surface of the flexible dielectric backing film, wherein the temperature sensor and the flexible heating element are supported adjacent to each other on the adhesive on the surface of the flexible backing film. The heater assembly allows for a more precise measurement of the heater temperature to be obtained while simplifying the assembly process.
