Pipe winding equipment used for winding pipe-winding-type heat exchanger core

Abstract

The invention relates to pipe winding equipment used for winding a pipe-winding-type heat exchanger core. The pipe winding equipment used for winding the pipe-winding-type heat exchanger core is characterized by comprising a supporting ring (1), a rotating ring (3), a first driving part (4) and a second driving part (5), wherein a core body (2) is sleeved with the supporting ring (1), and the supporting ring (1) can move relatively in the axial direction of the core body (2) under the action of external force; the core body (2) is sleeved with the rotating ring (3), the rotating ring (3) can be rotatably restrained on the supporting ring (1), and the rotating ring (3) is provided with a winding structure on which heat exchange pipes (21) are wound; the first driving part (4) acts on the rotating ring (3), and is used for driving the rotating ring (3) to rotate relative to the supporting ring; and the second driving part (5) acts on the supporting ring (1), and provides the external force to drive the supporting ring (1) to move axially, so that the heat exchange pipes (21) are spirally wound on the periphery of the core body (2). Compared with the prior art, the pipe winding equipment for winding the pipe-winding-type heat exchanger core has the advantage that the risks that winding-in and winding-out ends of the core body deviate, and the heat exchange pipes are abraded can be reduced.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, and in particular relates to a tube winding device for winding a core body of a tube-wound heat exchanger. Background technique [0002] At present, the core body of the tube-wound heat exchanger is made by rotating the core body to wind the heat exchange tube on the core body, such as the invention patent "a tube winding machine" with the patent number CN201410663041.9 (the authorized announcement number is CN104444563A ) discloses a pipe winding machine, which includes a supporting wheel for carrying the pipe to be wound, a pipe feeding device and a pipe unwinding device, and the pipe feeding device sequentially includes a pipe feeding base, a lifting mechanism, a fine adjustment mechanism, a support seat, a radial Adjusting mechanism and supporting wheel; the tube unwinding device includes a tube unwinding base, on which a chassis is provided, a bracket is provided on the chassis, a tu...

AI Technical Summary

Problems solved by technology

[0004] With the enlargement of the tube-wound heat exchanger, the existing tube-winding machine has the following technical problems to be solved: the existing tube-winding machine usually winds the heat exchange tube on the periphery of the core body through the rotation of the core body. With the increase in the size of the wound tube heat exchanger, the number of rotations of the core body has increased significantly, and long-term rotation will cause problems such as deviation of the core body's winding in and out, and wear of the heat exchange tube.
