Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a drainage structure and a heat exchanger. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.

[0003] For example, the utility model with application number CN202020357119.5 discloses a heat exchanger. In this utility model, when air enters the air flow channel, part of the air flowing forward along the surface of the fin will enter the diversion groove, and the diversion groove will then guide this part of the air to the leeward side of the heat exchange tube, thereby strengthening the air disturbance in this area. In this way, the area will not form a wake zone of low-speed reflux, and the heat exchange effect is enhanced. As a result, the heat exchange between the heat exchange tube, the fin, and the air is more sufficient, and the heat exchange efficiency of the heat exchanger is greatly improved. At the same time, the raised diversion convex portion can also force the air to generate a secondary flow perpendicular to the fin, increase the flow distance of the air in the air flow channel, and prolong the contact time between the air and the fin, thereby further improving the heat exchange capacity of the heat exchanger. However, in actual use of this type of heat exchanger, when the spoiler convex portion turbules the airflow, it will also block part of the airflow from flowing to the central interior of the annular spoiler convex portion, thereby reducing the amount of air flow between the airflow and the fin, thereby affecting the heat exchange efficiency of the fin.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a drainage structure and a heat exchanger are provided. Utility Model Content
