Abstract
Multi-passage heat exchange element which includes an elongated central first fluid passage for passage of a first fluid of a heat exchanger, a plurality of substantially helically convoluted second fluid passages for a second fluid of a heat exchanger, the second fluid passages substantially helically surrounding at least a portion of the elongated central passage, and a plurality of substantially helically convoluted first fluid passages for passage of the first fluid of a heat exchanger, the first fluid passages substantially surrounding at least a portion of the second fluid passages.
Claims37
A method of exchanging heat, comprising:
- passing a first fluid through a central fluid passage of a heat exchanger;
- passing a second fluid through a plurality of substantially helically convoluted second fluid passages of a heat exchanger, the second fluid passages substantially surrounding at least a portion of the central fluid passage, wherein a cross-section of at least one of the second fluid passages is substantially oval or tear shaped;
- and
- passing the first fluid through a plurality of substantially helically convoluted first fluid passages of the heat exchanger, the first fluid passages substantially surrounding at least a portion of the second fluid passages.
A method of exchanging heat, comprising:
- passing a first fluid through a central fluid passage of a heat exchanger;
- passing a second fluid through a plurality of substantially helically convoluted second fluid passages of a heat exchanger, the second fluid passages substantially surrounding at least a portion of the central fluid passage;
- passing the first fluid through a plurality of substantially helically convoluted first fluid passages of the heat exchanger, the first fluid passages substantially surrounding at least a portion of the second fluid passages;
- and
- wherein a combination comprises the first fluid passages, the second fluid passages, and the central fluid passage, and wherein a cross-section of the combination is substantially orthogonal.
A method of exchanging heat, comprising:
- passing a first fluid through a central fluid passage of a heat exchanger;
- passing a second fluid through a plurality of substantially helically convoluted second fluid passages of a heat exchanger, the second fluid passages substantially surrounding at least a portion of the central fluid passage, wherein the central fluid passage and the second fluid passages comprise a heat exchange element of single-piece construction;
- and
- passing the first fluid through a plurality of substantially helically convoluted first fluid passages of the heat exchanger, the first fluid passages substantially surrounding at least a portion of the second fluid passages.
