Abstract
A Heater-Cooler unit that provides efficient heating and cooling in such a manner that the temperature is easily controlled. The unit's 360 degree exposure enables both fins and barrel surface to be in complete contact with cooling air. The structure of the fins provides contact with the barrel to conduct heat flowing from the heating elements to the barrel surface.
