摘要： A helical heat exchanger assembly comprises a plurality of helical heat exchangers, each helical heat exchanger comprising a tube having first and second ends, a length, an inner diameter and a cross-section incorporating the inner diameter, a thermally conductive tube insert having a length and an outer diameter substantially equal to the inner diameter of the tube, the tube insert having first and second ends and comprising a single helix extending along the length of the tube insert and twisted around a central axis. The tube insert is sealed within the tube by sealing an outer edge of the helix to an inner surface of the tube to form fluid-tight first and second fluid flow paths defined between opposing sides of the helix and the inner surface of the tube, respectively. A plurality of inlet and outlet fluid ports are positioned for passage of a first and second fluid into and out of each tube. A first manifold connects each of the first ends of the heat exchanger tubes and a second manifold connects each of the second ends of the heat exchanger tubes, wherein at least one of the first or second manifolds includes baffles to direct fluid flow within the manifold such that at least some of the helical heat exchangers may be arranged in series, or in parallel, within the heat exchanger assembly via the baffles. Each helix has a predetermined pitch which may be less than or greater than the tube inner diameter and defines a length of the first and second fluid flow paths within each heat exchanger tube, wherein the pitch of the helix may be constant or variable along the length of the tube insert.

摘要： A heat exchanger assembly comprising a tube with a thermally conductive tube insert sealed therein, the tube insert having a substantially similar cross-section to the cross-section of the tube, and a plurality of fluid ports for passage of fluid into and out of the tube, the fluid ports arranged for counterflow operation. The tube insert includes a pair of helices extending along the length of the tube insert, the helices having first and second sides offset from each other by a predetermined distance along the length of the tube insert and first and second ends, each of the first ends offset from the other by a predetermined angle and each of the second ends offset from the other by a predetermined angle. The tube insert is sealed within the tube to form a first fluid flow path and a second fluid flow path, the first fluid flow path defined between the first sides of the helices and the second fluid path defined between the second sides of the helices.
