  • Rheometer having resistance heater and cooling device
    Patent number: 11692921
    Abstract: Described are a method and device for controlling a temperature of a sample. The sample may be a rheometer sample. A thermal control system comprising a geometry element, heat conductor element, heater element, cooling device and thermal resistance layer is used. The cooling device may be a Peltier element. The heat conductor element is disposed adjacent to and in thermal communication with the geometry element. The heater element is in thermal contact with the heat conductor element. The thermal resistance layer is disposed between and in thermal contact with an element surface of the heat conductor element and a cooling surface of the cooling device. The heater element is operated to cause heat to flow to the geometry element and the cooling device is operated to cool the cooling surface to a temperature that is less than a temperature of the element surface.
