Title:
HEAT EXCHANGER AND AIR TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/186302
Kind Code:
A1
Abstract:
Provided are a heat exchanger and an air treatment device. A heat exchanger according to the present invention includes a plurality of core fins and a plurality of films. The core fins and the films are alternately layered and form an airflow passage. The plurality of core fins include first core fins and second core fins, the airflow passage being formed between the first and second core fins. The airflow passage is provided with two port sections that are disposed facing each other. One of the port sections is an inlet section, and the other of the port sections is an outlet section. An airflow flows from the inlet section to the outlet section along an airflow direction. At least the outermost-side height of at least one of the port sections in the layering direction of the first and second core fins is greater than the height at other positions between the inlet section and the outlet section of the airflow passage. Using the heat exchanger according to the present invention reduces the resistance occurring when the airflow enters the heat exchanger and results in a smoother flow in the airflow. Thus, as a result of an increase in flow speed inside the heat exchanger, the heat exchange efficiency of the heat exchanger is improved.
