摘要： A heating device for heating a fluid, comprising a heating element (1), a first dissipating element (2) and a first casing (4), having a substantially tubular shape, which encloses said first dissipating element (2) and, at least partially, said heating element (1), said first dissipating element (2), said heating element (1) and said first casing (4) being positioned so that said first dissipating element (2), substantially shaped as an helicoid and placed around said heating element (1), is in contact with said heating element (1) and with said first casing (4) so that they define a first channeling path for the fluid to be heated by means of the heat produced by the heating element (1), characterized in that said dissipating element (2) is built integrally, or in one piece, with said heating element (1).

摘要： A heat exchanger (1) for gas condensing boilers is provided with a container body (2) within which at least one pipe bundle (3) is disposed to delimit a combustion chamber (300). The at least one pipe bundle (3) is made by a pipe spiral wound around a central axis. A first end (31) of the pipe serves as an inlet for the heat transfer fluid to be heated. A second end (32) of the pipe serves as an outlet for said heat transfer fluid. The pipe bundle (3) is made as a single component defined by a seamless single element. The pipe bundle has an elliptical section with said ends (31; 32) having a circular section projecting from said container body (2), so as to be accessible from the outside, to ease the operations of connection of the ends (31; 32) to the pipes of the water system. A method of manufacturing the pipe bundle (3) involves shaping an elliptical section of a pipe by mechanical processes for plastic deformation, so as to obtain a change of section, from elliptical to circular, thus allowing a metallic continuity between the exchanger and the pipes of the water system.

摘要： The invention relates to an apparatus (1) and method for heating a liquid, such as water, flowing into and through said apparatus (1) from an associated liquid source. The apparatus comprises a burner unit (60) and a coil (5) arranged in an internal housing (30), said internal housing (30) arranged inside an external housing (40) dimensioned so as to form a liquid reservoir (50) in between said two housings (30, 40) and wherein said burner unit (60) is arranged so as to direct a flame towards said coil (5). The liquid flows into the apparatus through a liquid inlet into said liquid reservoir (50) and from said liquid reservoir (50) through the coil (5) from a coil inlet to a coil outlet, and wherein the coil (5) and internal housing (30) are arranged so as to direct the flame from the burner unit (60) through a tortuous path ensuring a high energy transfer from said flame to said liquid. This design is advantageous for integration of the apparatus into a compact device, since the cool water surrounds the hot internal part of the apparatus. Thus, the external surface of the apparatus is cool enough to allow sensitive components to be placed close to the external housing (40), and at the same time, the apparatus provide a high energy efficiency.
