Title:
METHOD FOR PROCESSING HEAT EXCHANGER AND PUSHING DEVICE FOR PROCESSING HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2022/218428
Kind Code:
A1
Abstract:
Provided are a method for processing a heat exchanger and a pushing device for processing a heat exchanger. The method for processing a heat exchanger comprises the following steps: preparing a heat exchanger, wherein a bent section of one heat exchange pipe in the heat exchanger is at least partially in contact with a bent section of another heat exchange pipe adjacent to the heat exchange pipe in the lengthwise direction of a first pipe; placing a pushing member, such that at least part of the pushing member is in contact with at least part of a bent section of at least one heat exchange pipe; and moving the pushing member to drive the bent section to rotate by a preset angle or move a preset distance relative to a first section connected to the bent section, and/or moving the heat exchange pipe to enable the bent section to rotate by a preset angle or move a preset distance relative to the first section connected to the bent section, such that the bent section of one heat exchange pipe is not in contact with the bent section of the other heat exchange pipe adjacent thereto in the lengthwise direction of the first pipe.
