Air-liquid heat exchanger

Abstract

An air-liquid heat exchanger consists in an insulated chamber adapted to allow hot air to pass therethrough. A coil member extends through the insulated chamber and is adapted to allow a heat transfer liquid to pass into and then out of the insulated chamber. There is at least one bracket adapted to hold the coil member in a predetermined position and spacing between the windings of the coil within the insulated chamber, and at least one baffle member placed between the coil member and an interior surface of the insulated chamber and adapted to slow down the speed of air flow through the insulated chamber. A slower air speed increases the time and number of contactrs between the hot air and the coil member and thereby allows for an efficient exchange from the hot air to the heat transfer liquid.
