Title:
HEAT EXCHANGER AND METHOD FOR PROCESSING HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2023/051829
Kind Code:
A1
Abstract:
A method for processing a heat exchanger (100), and a heat exchanger (100). The method for processing the heat exchanger (100) comprises the following steps: preparing a plurality of heat exchange tube (4) semi-finished products, each of the heat exchange tube (4) semi-finished products comprising a first wall (40) and a second wall (42) that are arranged in a thickness direction of the heat exchange tube semi-finished product, and the second wall (42) having a first gap penetrating the second wall (42) in the thickness direction; arranging N heat exchange tube (4) semi-finished products spaced apart by a predetermined distance in a first direction, N being greater than 4, the thickness direction of the heat exchange tube (4) semi-finished product being parallel or angled to the first direction, and in the first direction, the arranged heat exchange tube (4) semi-finished products being sequentially defined as a first tube, a second tube,…, an N-1th tube, and an Nth tube; placing the second wall (42) of the Nth tube toward the second tube; and placing the second wall (42) of the Nth tube toward the N-1th tube. The present invention facilitates the reduction of stress concentration of the heat exchanger (100), and the reliability and service life of the heat exchanger (100) are improved.
