Abstract
A heat exchanger has a primary circuit formed by a serpentine tube with parallel sections spaced to receive open ended tubes preferably of the same diameter between and around the primary tube sections in the natural arrangement of six about one. A secondary fluid may pass through these open-ended tubes in lengthwise manner and over the return bends of the primary circuit, lengthening the distance for contact and enhancing heat transfer. This arrangement permits a more compact heat exchanger and greater utilization of heat transfer surfaces. A pair of the exchangers can be operated as evaporators in series in alternating sequence for continuous defrosting.
Claims5
A heat exchanger having primary and secondary conduits in heat-exchanging relationship, wherein the improvements comprises:
- at leat one serpentine tube having parallel sections connected by reverse bends, said serpentine tube constituting one of said conduits;
- a group of open-ended tubes disposed adjacent to the said parallel sections, said open-ended tubes constituting the other of said conduits, and forming a continuous mass of contacting tubes extending between and surrounding said serpentine tube sections;
- and
- means securing said mass of tubes together to form a predetermined cross-section of the entirety of said mass of open-ended tubes and tube sections.
