Problems solved by technology
The interior of the existing heat exchange copper tubes is generally smooth. When the copper tube passes the refrigerant in the tube, the contact area between the flowing refrigerant and the copper tube is small, and the residence time is short, thereby reducing the heat exchange efficiency.
At the same time, due to the thin wall of the heat exchange tube, it is easy to bend and deform during actual use.

Embodiment Construction
[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0011] Such as figure 1 As shown, in this embodiment a Reinforced heat exchange tubes with diversion grooves , including a pipe body 1, the inner wall of the pipe body 1 is evenly arranged with diversion grooves 2 at intervals, the diversion grooves 2 are arranged helically along the inner wall of the pipe body 1, the groove depth of the diversion groove 2 is 2-3mm, and the groove The ratio of the depth to the wall thickness of the pipe body is 1:3, and a plurality of evenly spaced ribs 3 are arranged on the outer wall surface of the pipe body 1. The outer diameter of the pipe body 1 is 30-50mm, and the adjacent guides The distance between the launders is 5-6mm.
[0012] The heat exchange tube with the above structure has a larger heat exchange area, and the heat exchange efficiency is improved.

The invention relates to a reinforced heat exchange tube with a diversion trench. The reinforced heat exchange tube comprises a tube body (1) and is characterized in that the diversion trenches (2) are uniformly formed in the inner wall of the tube body at intervals, the diversion trenches (2) are in helix arrangement along the inner wall of the tube body (1) and have the depth of 2-3 mm and the depth and wall thickness ratio of 1:3, a plurality of reinforcing ribs (3) are uniformly arranged on the outer wall surface of the tube body (1) at intervals, the tube body (1) has the external diameter of 30-50 mm, and the distance between the adjacent diversion trenches (2) is 5-6 mm. When the reinforced heat exchange tube serves as an air-conditioning heat exchange tube, the heat exchange efficiency is improved.
Description
technical field [0001] The present invention relates to mainly used in the manufacture of heat exchangers heat exchange tube , specifically involving a Reinforced heat exchange tubes with diversion grooves . Background technique [0002] Heat exchangers such as evaporators and condensers mainly use heat exchange copper tubes to achieve heat exchange. The interior of the existing heat exchange copper tubes is generally smooth. When the copper tubes pass the refrigerant in the tubes, the contact area between the flowing refrigerant and the copper tubes is small, and the residence time is short, thereby reducing the heat exchange efficiency. At the same time, since the tube wall of the heat exchange tube is relatively thin, it is easy to bend and deform during actual use. [0003] For different heat exchange needs, the internal thread often needs to be designed into a thread structure with different regular arrangements of the corresponding tooth profile. Continuously impro...
