Abstract
This is a heat liquid exchanger unit particularly adapted for use with situations where the heating liquid is under low pressure gravity flow at a relatively slow flow rate and constitutes a pair of outer flow passages for the gravity flow heating liquid, which surround an inner replenisher liquid flow chamber through which liquid under controlled rate of flow passes so that the flow rate of the replenisher liquid is equalized with the flow rate of the discharge liquid, the panels between the outer passages and the inner chamber being of thin wall high heat transfer construction and being specifically formed to provide a torturous path for the liquid through the inner chamber, the outer chambers also have a series of spaced divider brackets forming a torturous path through the outer passages.
