Embodiment Construction

[0031] like Figure 1-4 As shown, the present invention provides a flooded heat exchange tube, which includes:

[0032] The tube base 1 and the first tooth 2 and the second tooth 3 arranged on the outer wall of the tube base 1, the first tooth 2 is away from the outer wall of the tube base 1 and towards the second tooth 3, the second tooth 3 protrudes from the outer wall of the tube base 1 in a direction away from the outer wall and toward the first tooth 2, and between the first tooth 2 and the A semi-closed evaporation chamber 4 is formed between the second teeth 3 , and outwardly protruding wing tips 5 are also provided on the first teeth 2 and / or the second teeth 3 .

[0033] The present invention can effectively form a semi-closed evaporation chamber between the first tooth and the second tooth by setting the first tooth and the second tooth on the outer wall of the tube base, and making the first tooth and the second tooth extend relatively. At least one of the two tee...

Abstract

The invention provides a flooded heat exchange tube, a flooded heat exchanger and an air conditioner. The flooded heat exchange tube comprises a tube base body (1), first teeth (2) and second teeth (3), wherein the first teeth (2) and the second teeth (3) are arranged on the outer wall of the tube base body (1); the first teeth (2) extend out from the outer wall of the tube base body (1) in the direction away from the outer wall and facing the second teeth (3); the second teeth (3) extend out from the outer wall of the tube base body (1) in the direction away from the outer wall and facing the first teeth (2); a semi-closed evaporation cavity (4) is formed between the first teeth (2) and the second teeth (3); and the first teeth (2) and/or the second teeth (3) are further provided with fin tips (5) protruding outwards. By means of the flooded heat exchange tube, the flooded heat exchanger and the air conditioner, the evaporation heat exchange efficiency and the condensation heat exchange efficiency of the heat exchange tube can be improved under the heating work condition and the refrigeration work condition, and the machining difficulty of the heat exchange tube is effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and in particular relates to a flooded heat exchange tube, a flooded heat exchanger and an air conditioner. Background technique [0002] The flooded heat pump tube is a key component of the flooded heat pump unit. As a heat exchange tube that can perform both evaporation and condensation functions, it has been highly valued by researchers at home and abroad for a long time. Compared with pure evaporating tubes and condensing tubes, the existing flooded heat pump tubes often achieve different heat exchange effects in heating and cooling conditions. The reason is: when the heat pump tube is used as an evaporating tube, the tooth profile designed for condensation cannot reach the tooth profile designed for evaporation when the refrigerant evaporates; The tooth profile designed for the action cannot reach the tooth profile designed for the condensation action when the refrigerant condenses. ...
