Abstract

The invention provides a supercooling pipe and an air conditioning unit. The supercooling pipe comprises a pipe body and a plurality of fins arranged on the outer surface of the pipe body, wherein thefins are arranged in a wavy shape in the length direction, and a wavy channel is formed between every two adjacent fins. According to the technical scheme, on one hand, the heat exchange area of thefins is increased by arranging the fins in the wavy shape; and on the other hand, the wavy channel is formed between every two adjacent fins, and a refrigerant can be repeatedly baffled and disturbedby wavy structures when flowing through the wavy channels, so that the fluid disturbance strength is continuously enhanced, boundary layers on the fins are damaged to lower thermal resistance, the refrigerant can flow in the wavy channels to strengthen heat exchange, and heat is conducted away in time.

Description

Technical field [0001] The invention relates to the technical field of air conditioning equipment, and in particular to a supercooling pipe and an air conditioning unit. Background technique [0002] In central air-conditioning water-cooled horizontal condensers, in order to further improve the energy efficiency of the unit, a built-in supercooling structure is often installed at the bottom of the condenser. Among the existing supercooling structures, baffle, immersion, and flashing structures are currently widely used supercooling structures. In the baffled supercooling structure, the inside of the heat exchange tube is the cooling water, and the outside of the tube is the liquid refrigerant that baffles and flows under the action of the baffle. During the flow of the refrigerant, the heat is transferred to the cooling water in the tube through the tube wall to achieve The purpose of reducing the temperature of the refrigerant and increasing the degree of subcooling.
