Heat exchange tube and air conditioner

Abstract

The invention provides a heat exchange tube and an air conditioner. The heat exchange tube comprises a tube body and fins arranged on the outer side of the tube body, longitudinal tooth structures areformed on the tops of the fins, transverse tooth structures are formed on the side portions of the fins, between every two adjacent fins, and the transverse tooth structures on the two fins are arranged in a staggered mode in the vertical direction to form a zigzag evaporation cavity. Due to the fact that the heat exchange tube is provided with the zigzag evaporation cavity, compared with an existing heat exchange tube which can form a plurality of small evaporation cavities, more evaporation cores can be provided, more bubbles are generated, meanwhile, due to the semi-sealing performance ofthe zigzag evaporation cavity in the discharging process of the bubbles, and refrigerants in the cavities are subjected to the strong turbulent flow effect; and according to heat exchange tube, due tothe fact that the transverse tooth structures are arranged in the staggered mode, the paths of bubbles at the roots of the fins change continuously in the discharging process, the turbulent flow effect is further enhanced, and the evaporation efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat exchange tube and an air conditioner. Background technique [0002] The heat pump unit has a more comfortable user experience due to both heating and cooling, and is gradually being promoted. Due to the special requirements of the heat exchange mode of the heat pump unit, the heat exchange tubes required by the unit must have the functions of evaporation and condensation. As for the existing heat exchange tubes, due to the different heat exchange principles of evaporation and condensation, the two tube structures are quite different. The evaporation tube follows the "nucleation theory" and tends to process various grooves or various micro-closed evaporation chambers; while the condenser tube is often based on the "Gregorig" effect and tends to process various sharp fins in order to reduce The thickness of the liquid film of the refrigerant fluid. [0003] At present, ...
