Patent ID: 6976364

Claim:
An arrangement for regulating the temperature of a flowing material comprising: a supply arrangement delivering the material under pressure; a temperature regulator receiving the material under pressure from the supply arrangement; a dispensing device that receives the flowing material from the temperature regulator and dispenses the flowing material; in which: the temperature regulator comprises: a thermally conductive metal block that has a material inlet and a material outlet; at least one flow channel extending in a direction of flow through the metal block between the material inlet and the material outlet, the material flowing through the at least one flow channel; electrically controllable thermoelectric elements adjacent to and in thermal contact with the metal block; at least one temperature sensor generating a measured temperature signal; an element controller electrically connected with the thermoelectric elements and having, as input signals, at least a desired temperature signal (T — ref) and the at least one measured temperature signal, the element controller regulating the electrical state of the thermoelectric elements by generating a temperature control signal (T — c) as a function of the input signals to cause the thermoelectric elements to thermally influence the material flowing through the metal block.
