Problems solved by technology

[0002] Most of the existing spiral plate heat exchangers have non-uniform winding of the heat exchange plate, which causes various problems. The width of the seam is different, and it is easy to produce leaks during welding. When the heat exchanger is working, due to the uneven thickness of the cross-section of the heat exchange channel, it affects the speed of liquid passing, which affects the heat exchange efficiency and other problems, resulting in the winding of the heat exchange plate. The direct cause of the inhomogeneity is that it is directly wound durin...

Embodiment 1

[0020] Embodiment one: see attached figure 1 shown.

[0021] A detachable spiral heat exchanger, which includes a shell 1, two pairs of outlets (not shown in the figure) and inlets 2 arranged on the shell 1, a first heat exchange plate 3 and The second heat exchange plate 4 also includes a support frame, a partition plate 5 is arranged in the support frame, and the first heat exchange plate 3 and the second heat exchange plate 4 are spirally wound around the support frame as the center, The first heat exchange plate 3 and the second heat exchange plate 4 are respectively fixedly connected to the two sides of the separator, and the gap between the first heat exchange plate 3 and the second heat exchange plate 4 is divided into independent first heat exchange plates. channel and the second heat exchange channel.

[0022] The support frame includes a semi-cylindrical hollow first support frame 6 and a second support frame 7 , the first support frame 6 and the second supp...

Abstract

The invention discloses a detachable spiral heat exchanger and a manufacturing method thereof. The detachable spiral heat exchanger comprises a shell, two pairs of outlets and inlets, a supporting framework, a first heat exchange plate and a second heat exchange plate, the outlets and the inlets are arranged on the shell, and the first heat exchange plate and the second heat exchange plate are arranged in the shell and are spirally alternately wound by taking the supporting framework as a center. As the supporting framework is firstly arranged and then the first heat exchange plate and the second heat exchange plate are wound by taking the supporting framework as the center, uneven deformation of the first heat exchange plate and the second heat exchange plate can be effectively prevented in winding.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a detachable spiral heat exchanger and a manufacturing method thereof. Background technique [0002] Most of the existing spiral plate heat exchangers have uneven winding of the heat exchange plate, which causes various problems. For example, due to the uneven width of the weld at the edge of the heat exchange plate, leakage points are prone to occur during welding. During work, due to the uneven thickness of the cross-section of the heat exchange channel, it affects the speed of liquid passage, thereby affecting the heat exchange efficiency and other issues. The direct cause of the uneven winding of the heat exchange plate is that it is directly wound during the production process. A bracket is added to the center of the winding, such as the published patent CN101749972A, which uses the method of directly winding the steel plate into a spiral body to produce the heat exchanger, which lead...
