ABSTRACT:
A heat exchanger is provided, comprising a housing defining a cavity therein, the housing having an inlet and outlet for feeding fluid into, and removing fluid from, the cavity of the housing, a pair of fixed spaced head plates fixed to the housing at either end of the cavity to preclude passage of fluid past the plates between the housing and plates, a pair of second head plates, one for each fixed head plate and secured to the side of the fixed head plate remote the other fixed spaced head plate, at least one of which second plates being removably secured to the fixed head plates, a gasket positioned between the fixed head plates and second plates, the housing further comprising covers for covering the head plates and providing a space between the head plates and cover, a pair of spacer plates secured to the housing between the fixed head plates, each spacer plate positioned adjacent each fixed head plate, the spacer plates permitting fluid within the cavity to flow therethrough, each of the fixed and secured removable head plates having a plurality of aligned apertures therethrough, the apertures being arranged in staggered rows of apertures through the plates, each spacer plate adjacent each set of head plates having staggered rows of apertures oriented with respect to the staggered rows of apertures in the head plates and the staggered row of apertures through the other spacer plate to secure lengths of tubing extending between opposed head plates, through apertures in the spacer plates, lengths of heat conducting metal tubing secured to open into the staggered apertures in the opposed head plates and extending through the apertures in the spacer plates, to provide staggered rows of tubing, the tubing being bowed in their length between the spacer plates to extend into spaces created in the cavity arising from the staggering of the rows of tubing, 180.degree. heat conducting metal U-Bends secured in the spaces between the removably secured head plates and cover for connecting the apertures through the removable head plates to connect the lengths of tubing to create a continuous flow path for fluid passing therethrough, from the tubing inlet to the tubing outlet leading into and out of the heat exchanger and an inlet and outlet into and from the tubing passing through the exchanger.
