Abstract
A heating assembly includes a heater extending in a longitudinal direction from a first end to a second end. Heat transfer fins are thermally coupled to the heater and extend in a direction transverse to the longitudinal direction. An airflow component is positioned proximate one of the first and second end and is configured to generate airflow along the plurality of heat transfer fins toward the other of the first and second end.
Claims15
A heating assembly, comprising:
- a heater including a cartridge heater disposed in a metal bore, the heater extending in a longitudinal direction from a first end to a second end;
- a plurality of heat transfer fins thermally coupled to the heater and extending in a direction transverse to the longitudinal direction;
- an airflow component positioned proximate one of the first and second end and configured to generate airflow along the plurality of heat transfer fins toward the other of the first and second cud.
A method of heating a device, the method comprising:
- coupling an air distribution block to a source of air′ to receive input air from the source of air;
- providing a heating assembly having a heater and a plurality of heatsink fins extending from the heater;
- generating air flow from a plurality of air apertures in the air distribution block along the heatsink fins;
- coupling the beater to a thermal cutoff switch using a heat pipe;
- and
- controlling the heater using, the thermal cutoff switch.
