Abstract
An improved heat exchanger in which a housing defines an annular space containing coolant and a tube for carrying working fluid through the coolant. On the top end of the casing there is a cover that seals the annular space and provides entry and exit portals for the tube and the coolant. Maintenance and/or cleaning of the heat exchanger is accomplished by removing the cover and pulling the tube from the annular space. Baffles formed from flexible sheets of material isolate the surface of the coil from the housing thereby reducing corrosive bonding and easing the removal process. Tapered edges along the annular space also help overcome any binding that might occur between the housing and the coil or the baffles.
