Abstract

The invention provides a heat exchange pipe and a heat pump unit. The heat exchange pipe comprises a pipe body and fins arranged on the outer surface of the pipe body. Condensation heat exchange structures are formed on the fins, and evaporation heat exchange structures are formed between the fins and the outer surface. The condensation heat exchange structures comprise fin table heat exchange structures which are formed on the two sides of the tops of the fins. The heat exchange pipe can be suitable for the refrigerating condition and the heating condition of the heat pump unit simultaneously, and thus the manufacturing cost of the heat pump unit is lowered.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat exchange tube and a heat pump unit. Background technique [0002] The air source screw heat pump unit can cool in summer and heat in winter. The cooling and heating functions can be switched at any time according to needs. Its versatility is favored by the market, especially for medium-sized commercial buildings in hot summer and cold winter areas. widely used in. In the early stage, the structure of the evaporator used in the heat pump unit was mainly a dry evaporator, but the heat exchange efficiency of the dry evaporator was low. In recent years, the flooded evaporator and the falling film evaporator have high heat transfer efficiency and the energy efficiency of the unit It is widely used in heat pump units. When the flooded or falling film heat pump unit is in the cooling condition, the outside of the tube is a low-pressure saturated liquid refrigerant, and th...
