Problems solved by technology

This leads to cumbersome production process of high-efficiency heat exchange tubes and low production efficiency
[0006] Thirdly, because the surface of the continuously rolled strip is full of grooves, the expansion joint between the tube plate and the tube sheet after being prepared into a heat exchange tube is not tight due to the existence of the groove at the tube end, or the expansion joint of the tube expander is easy. The problem of being damaged by grooves, increasing production costs

Embodiment 1

[0034] Refer to appendix Figure 1-3 , the pattern roll and the smooth upsetting roll are installed on the sliding shaft, the glossy roll is mounted on the fixed shaft, under the above production process, rolling 29.7mm width, 0.5mm thickness of the strip, by controlling the ginning and forming drive motor speed, at a production speed of 3m / min to produce a tooth height of 0.15mm, the number of internal patterns of 40 heads / inch of the C-shaped pattern efficient heat exchanger tube. Through the implementation of this process method, the production cost of the internal pattern high-efficiency heat exchanger tube is reduced by 20,000 yuan / ton, and the production efficiency is increased by 20%.

Embodiment 2

[0036] The pattern roll and the glossy upsetting roll are installed on the sliding shaft, the glossy roll is mounted on the fixed shaft, under the above production process, the strip with a width of 48.8mm and a thickness of 0.9mm is rolled, and by controlling the speed of the ginning and forming drive motor, the tooth height is 0.2mm at a production speed of 2.5m / min, and the number of threads is 45 heads / inch. Through the implementation of this process method, the production cost of cross-tooth pattern high-efficiency heat exchanger tubes is reduced by 23,000 yuan / ton, and the production efficiency is increased by 20%.

Embodiment 3

[0038] The pattern roll and the glossy upsetting roll are installed on the sliding shaft, the glossy roll is installed on the fixed shaft, under the above production process, the strip with a width of 59.0mm and a thickness of 0.7mm is rolled, and by controlling the speed of the ginning and forming drive motor, the tooth height is 0.16mm and the number of external patterns is 40 heads / inch C-shaped external pattern high-efficiency heat exchange tubes are made at a production speed of 3m / min. Through the implementation of this process method, the production cost of the external pattern high-efficiency heat exchanger tube is reduced by 30,000 yuan / ton, and the production efficiency is increased by 20%.

[0039] as Figure 4 As shown, the present invention may also produce a heat exchanger tube with an outer pattern.

Abstract

The invention discloses a production method and equipment of a high-efficiency heat exchange tube. The production method of a high-efficiency heat exchange tube of the present invention adopts the method of first rolling a U-shaped groove with a patterned roll, and then using an upsetting roll mechanism to form a U-shaped groove. The two sides of the opening are concave to form a narrow opening and a wide groove structure inside, and the rolled area and the unrolled area are formed by the method of intermittent rolling, so that the middle part of the pipe is a rolling area with a pattern, and the two ends are The smooth unrolled area is convenient for expansion at both ends and prevents the expansion joint from being loose. The invention realizes the continuous production of rolling and discontinuous rolling of the groove structure with narrow opening and wide inner groove formed by indentation on both sides of the opening of the groove on the heat exchange tube, which reduces production cost and improves production efficiency.

Description

Technical field [0001] The present invention belongs to the field of heat exchangers, in particular to a high efficiency heat exchanger tube production method and equipment. Background [0002] High-efficiency heat exchange tubes have a higher heat transfer coefficient than smooth surface tubes, so they have great application prospects in the fields of air cooling, seawater desalination and chemical industry with high heat exchange demand. [0003] In order to increase the efficiency of heat exchange, people have developed an efficient heat exchange tube such as Figure 1 As shown, its surface is formed with a C-shaped groove, so while increasing the surface area, because the opening width of the coggou is smaller than the bottom width, this can control the volume of the bubble, which is conducive to the formation of a continuous bubble column, which is conducive to further improving the heat transfer efficiency. [0004] However, this high-efficiency heat exchanger tube is less t...
