Problems solved by technology

[0004] One problem with such conventional spiral heat exchangers is that the installation of connecting pipes extending from the center of the spiral heat exchanger requires a relatively complicated manufacturing process
In particular, this problem relates to the difficulty of achieving the proper and desired positioning for the two connecting pipes and the header at the periphery of the helical part

Embodiment Construction

[0025] The spiral heat exchanger is described with reference to FIGS. 1-5. The spiral heat exchanger comprises a spiral heat exchanger element 1, see Figure 4 , and main connection element 2, see Figure 5 . In the embodiment described with reference to FIGS. 1-6 , the main connection element 2 is designed as a separate unit fitted into the spiral heat exchanger element 1 . It should be noted that, as an alternative, at least a part of the main connection element 2 may be an integral part of the spiral heat exchanger element 1 in the manner described below.

[0026] The helical heat exchanger element 1 comprises a central cylinder 5 and at least two helical thin plates 6 and 7, preferably made of metal, such as stainless steel, carbon steel, or titanium. The barrel 5 has a substantially cylindrical shape. Each sheet 6 and 7 has an inner end edge welded to the outer surface of the barrel 5 . The cylinder 5 is rotated about a central axis x in order to wind the sheets 6 an...

Abstract

The invention relates to a spiral heat exchanger including a central cylinder (5) and at least two spiral sheets (6, 7). The sheets extend from the cylinder to form a first spiral-shaped flow channel (8) for a first medium and a second spiral-shaped flow channel (9) for a second medium. The cylinder forms an inner space within the cylinder. The cylinder includes a first opening (11) communicating with the first flow channel and a second opening (12) communicating with the second flow channel. A pipe (14) extends into the inner space of the cylinder. A first communication channel, communicating with the first flow channel via the first opening, is formed within the pipe. A second communication channel, communicating with the second flow channel via the second opening, is formed in the inner space outside the pipe.

Description

technical field [0001] This invention relates generally to spiral heat exchangers for various applications, and more particularly to spiral heat exchangers for recovering heat from problematic fluids that are inconvenient to handle in actual processes, such as mud. In particular, the invention relates to a helical heat exchanger comprising a central cylinder and at least two helical sheets extending from the cylinder along respective helical paths around a common central axis and formed at least for A first helical flow channel for a first medium and a second helical flow channel for a second medium, wherein the barrel extends around the central axis and forms an interior space within the barrel, and the barrel includes a front end , a rear end, at least one first side opening communicating with the first flow channel, and at least one second side opening communicating with the second flow channel. Background technique [0002] Such a spiral heat exchanger is disclosed in S...
