Abstract
A heat exchanger for exchanging heat between fluids comprising a conduit for flow of a first fluid therethrough comprising a manifold with a single port in one area and a pair of ports in another area and a plurality of spaced fluid tubes attached to the pair of ports with the combination of the plurality of tubes having outer peripheral surfaces describing a cylinder and the inner confronting peripheral surfaces spaced apart to provide an open area therebetween for flow of a second fluid therethrough and means for directing the second fluid over and around both the inner and outer peripheral surfaces and through the open area between the tubes for achieving maximum surface area heat transfer with minimum cross sectional area of the conduits.
Claims12
A heat exchanger for exchanging heat between fluids, comprising:
- a plurality of conduits for parallel flow of a first fluid through all said conduits, each said conduit comprising a manifold with a first port at one end and a plurality of adjacent second ports spaced from said first port and a plurality of fluid tubes each attached to one of said plurality of ports, the outer peripheral surfaces of the plurality of tubes of each said conduit substantially describing a conduit cylinder and the inner confronting surfaces of said tubes of each conduit being spaced apart to provide an open fluid flow area between the tubes;
- means for directing a first fluid through all said conduits and thereby all said tubes;
- and means for directing a second fluid over and around said outer peripheral surfaces and through said open areas between the tubes for achieving maximum surface area contact heat transfer with minimum cross sectional area of each of the conduits.
