  • Patent number: 11622419
    Abstract: Implementations described herein provide a method for processing a substrate on a substrate support assembly which enables both lateral and azimuthal tuning of the heat transfer between an electrostatic chuck and a substrate. The method includes processing a first substrate using a first temperature profile on a substrate support assembly having primary heaters and spatially tunable heaters. A deviation profile is determined from a result of processing the first substrate. The spatially tunable heaters are controlled in response to the deviation profile to enable discrete lateral and azimuthal tuning of local hot or cold spots on the substrate support assembly in forming a second temperature profile. A second substrate is then processed using the second temperature profile.

  • Patent number: 9731486
    Abstract: A heat exchange device for heating liquid adhesive material to an application temperature suitable for an adhesive bonding application includes a body having an inlet configured to receive a flow of liquid adhesive material and an outlet configured to provide the liquid adhesive material to a dispensing device for the adhesive bonding application. A fluid passageway in the body connects the inlet and the outlet. The fluid passageway includes a thin slit section in the form of an elongated ring shape, having a length along a fluid flow direction between the inlet and the outlet, the thin slit section further having a first dimension and a second dimension transverse to the fluid flow direction. The first dimension and the length are substantially greater than the second dimension. The heat exchange device further includes a heating element for heating the liquid adhesive material flowing through the thin slit section.

  • Patent number: 9609857
    Abstract: A device and a method to eradicate pests, specifically bed bugs by applying heat. The device includes a bag having an inner surface made of thermoreflective material. Preferably the walls and the bottom of the bag are double layered and at least one heater is inserted in between the double layers. The infested clothing is inserted into the bag and after closing the bag the heater is turned on for a short period of time to increase the temperature to 150-220 F. Once the temperature has been reached the heater is turned off and a minimum temperature of 150 F is maintained in the bag.

  • Patent number: 9523285
    Abstract: Energy storage systems and methods use medium voltage (MV) electrical heat exchangers to increase the efficiency of the energy storage system and/or reduce emission of pollutants. MV electrical heat exchangers use medium range voltages to heat a fluid, such as a gas or liquid. The heated fluid is used in the energy storage system to either drive a turbine generator directly or indirectly, such as by generating steam to drive the turbine generator. The electricity used to power the MV electrical heat exchangers can be from renewable energy sources, such as solar or wind-powered sources, further increasing efficiency of the energy storage system.

  • Patent number: 9435477
    Abstract: A piping system comprises a resistive heating circuit, a target heating surface, and a thermally conductive substrate adjoin (or abutting) both the heating circuit and the heating surface. The thermally conductive substrate can be composed of aluminum or some other material for heat spreading. A material for heat spreading has a thermal conductivity sufficient to evenly heat a section of the target surface within tolerance requirements of a sensitive application. The even heating can eliminate hot spots and cold spots of a temperature gradient along an axis of the piping system.
