Document Type and Number:
WIPO Patent Application WO/2022/193675
Kind Code:
A1
Abstract:
The present application provides a heat exchanger and an air conditioner having same. The heat exchanger comprises a liquid collection tube, an air collection tube, and a flat tube in communication with both the liquid collection tube and the air collection tube, and the heat exchanger further comprises a connecting tube in communication with the liquid collection tube, and a head end of the connecting tube which passes through the liquid collection tube and protrudes from the liquid collection tube, wherein the head end of the connecting tube is provided with a first sealing cover for sealing a port of the head end. A cooling medium can be sprayed into the liquid collection tube via the connecting tube, so that the sprayed cooling medium can reach the flat tube, which is located at a relatively high position in the liquid collection tube, making distribution of the cooling medium more uniform. In addition, the head end of the connecting tube passes through the liquid collection tube and then protrudes from the liquid collection tube, and the head end is sealed, which makes it possible to prevent the cooling medium from leaking at a connection between the liquid collection tube and the connecting tube and makes the structure of the connecting tube relatively stable.
