Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] Such as figure 1 As shown, the heat exchange tube according to the present invention includes: at least one spoiler section 1 ; and a spoiler structure 10 arranged in the refrigerant circulation channel of each spoiler section 1 . According to the heat exchange tube of the present invention, by setting the turbulence section 1 on the heat exchange tube, and setting the turbulence structure 10 in the flow channel of the turbulence section 1, the arrangement of the turbulence structure 10 can disturb the flow through the turbulence section 1 Refrigerant, which enhances the turbulent flow in the circulation channel, and increases the velocity gradient in the circulation channel, so that the refrigerant will be more fully in contact with the inner wall of the heat exchange tube, thereby increasing the heat transfer coefficient of the heat exchange tube ...

Abstract

The invention provides a heat exchange pipe, a heat exchanger and an air conditioning unit. The heat exchange pipe comprises at least one flow disturbing segment and flow disturbing structures. Each flow disturbing structure is arranged in a refrigerating fluid flowing channel of the corresponding flow disturbing segment. According to the heat exchange pipe, the heat exchanger and the air conditioning unit, the flow disturbing segments are arranged on the heat exchange pipe, the flow disturbing structures are arranged in the flowing channels of the flow disturbing segments, and refrigerating fluid flowing through the flow disturbing segments can be disturbed by means of arrangement of the flow disturbing structures; turbulent flow in the flowing channels is enhanced, the velocity gradient in the flowing channels is increased, and then the refrigerating fluid can be fully in contact with the inner wall of the heat exchange pipe; and therefore the heat exchange coefficient of the heat exchange pipe is increased, and the heat exchange performance of the heat exchange pipe, the heat exchanger and the air conditioning unit is improved.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a heat exchange tube, a heat exchanger and an air conditioning unit. Background technique [0002] The finned heat exchanger is the most widely used heat exchange equipment in gas and liquid heat exchange. The finned heat exchanger achieves the purpose of enhancing heat transfer by adding fins to the ordinary base tube. Finned tube heat exchangers are widely used in the field of refrigeration, so it is of great significance to study the heat transfer and resistance performance of the refrigerant inside the round tube of the finned tube heat exchanger. [0003] In the current finned heat exchanger, the refrigerant is arranged inside the circular tube, so as to realize the evaporation and condensation of the refrigerant through the flow of the refrigerant in the circular tube. However, due to the size of the circular tube, more refrigerant flows in the center of the circular tube, ...
