US 8,803,041 B2 · High-performance flow heater and process for manufacturing same

Abstract

A flow heater (100, 200, 300, 400, 500) with a tube arrangement including at least one tube (105, 106, 205, 206, 305, 306, 404, 405, 406) for passing through a fluid to be heated or a plurality of fluids to be heated, and with a heater with a metal jacket, especially with a tubular heating body (102, 202, 302, 402, 502), in which the tubes (105, 106, 205, 206, 304, 305, 306, 404, 405, 406, 505) surround the heater. At least in partial areas of the heater, wall sections (113, 114, 213, 214, 311, 312, 313, 411, 412, 413, 513) of the tube arrangement (105, 106, 205, 206, 304, 305, 306, 404, 405, 406), which wall sections face the heater, are adapted to an outer contour of the heater, which heater may or may not include a heat transport tube (117, 317, 517), so that the wall sections are in flush contact with sections of this outer contour. The tube arrangement (105, 106, 205, 206, 304, 305, 306, 404, 405, 406, 505) is connected together and/or with the heater by a connection device. A process for manufacturing such a flow heater is also provided.

Dependent claims

A flow heater comprising:

a heater with an outer contour and comprising a tubular heating body with a metal jacket;
and
a tube arrangement for passing through fluid to be heated, said tube arrangement comprising a first tube and a second tube, said tube arrangement surrounding said heater at least in some sections, said first tube comprising first tube wall sections facing said heater and said first tube having a first tube inner contour, said second tube comprising second tube wall sections facing said heater and said second tube having a second tube inner contour, said first tube inner contour and said second tube inner contour being adapted to said outer contour of said heater, whereby said first tube wall sections facing the heater and said second tube wall sections facing the heater are in flush contact with sections of said outer contour, wherein a sum of a dimension of said first tube inner contour and a dimension of said second tube inner contour substantially corresponds to a dimension of said outer contour.

A flow heater comprising:

a heater comprising a tubular heating body with a metal jacket;
and
a tube arrangement comprising a first tube and a second tube, said first tube receiving a first tube fluid to define a first fluid flow path, said second tube receiving a second tube fluid to define a second fluid flow path, said first tube comprising a first tube inner surface having a first tube inner contour, said second tube comprising a second tube inner surface having a second tube inner contour, said first tube inner contour surrounding a first portion of said heater, said second tube inner contour surrounding a second portion of said heater, said first tube inner contour facing said first portion of said heater, said second tube inner contour facing said second portion of said heater, said first portion of said heater comprising a first heater outer contour, said second portion of said heater comprising a second heater outer contour, said first tube inner contour substantially corresponding to said first heater outer contour, said second tube inner contour substantially corresponding to said second heater outer contour, wherein said first tube inner contour is in direct contact with said first heater outer contour and said second tube inner contour is in direct contact with said second heater outer contour.
