Abstract

The invention provides an evaporator and its evaporation tube, wherein the evaporation tube includes a tube body, a plurality of fins arranged on the outer wall of the tube body, and a semi-closed space is formed between two adjacent fins and the outer wall of the tube body. The feature is that at least one evaporation chamber located in a semi-closed space is provided on the side wall of the fin. In the evaporator and its evaporation tube provided by the present invention, the two pairs of arc-shaped evaporation chambers on the adjacent fins respectively form a continuous semi-closed cavity structure, thus greatly increasing the heat exchange area of ​​the evaporation tube and improving its efficiency. Heat transfer performance: Adjacent fins and the outer wall of the tube form a semi-closed space with an open end. When the air bubbles are discharged from the semi-closed opening between the fins, the internal semi-closed shape promotes the disturbance of the refrigerant, resulting in disturbance The flow effect promotes evaporation and accelerates the generation rate of bubbles, thus greatly improving the heat transfer efficiency under the mutual promotion of bubbles and turbulent flow.

Description

technical field [0001] The invention relates to the technical field of air-conditioning evaporators, and more specifically, relates to an evaporator and an evaporating tube thereof. Background technique [0002] The flooded evaporator has the advantages of high heat exchange performance, sufficient heat exchange, simple structure, easy cleaning and descaling, etc. As the original oil return problem of the flooded evaporator has been basically improved, it has an important role in the field of commercial air conditioning. Wide application prospects. The evaporator tube is the most important element in the flooded evaporator, so the improvement and optimization of the evaporator tube structure will play a vital role in improving the heat exchange performance of the evaporator. The flooded evaporation tube needs to form a semi-closed evaporation chamber structure, so that the refrigerant can evaporate and exchange heat in the evaporation chamber. [0003] However, with the co...
