Document Type and Number:
WIPO Patent Application WO/2022/166454
Kind Code:
A1
Abstract:
Disclosed in the present invention are a collecting tube assembly and a heat exchanger. The collecting tube assembly comprises a collecting tube and a connecting tube assembly. The connecting pipe assembly comprises an adapter and a steering member. The adapter comprises: a tubular part located outside the collecting tube; and a step part protruding inward from the inner surface of the tubular part at the end portion of the tubular part facing the collecting tube. The steering member comprises: an end wall, a connecting wall extending from the end wall along a direction intersecting the axial direction of the collecting tube, and a step part protruding outward from the connecting wall at the end portion of the connecting wall away from the end wall. The steering member is inserted into a through hole of the collecting tube by means of an inner hole of the adapter; the side of the step part of the steering member facing the end wall abuts against the step part of the adapter; and the part of the connecting wall inserted into the collecting tube is provided with openings that penetrate through the connecting wall. According to the collecting tube assembly of the present invention, direct impact of a fluid from an inlet on a flat tube is avoided, and the manufacturing and assembly processes are simple and the costs are low.
