Embodiment 1

[0016] Embodiment one: if figure 1 As shown, an enhanced heat transfer element includes a light pipe 1, which is characterized in that: the light pipe 1 is covered with an integral aluminum-rolled finned tube 2; the light pipe 1 is a threaded pipe;

[0017] Taking the bare pipe 1 as the base pipe, the smooth pipe is first rolled to form a threaded pipe 1, and then the pipe is covered with aluminum rolled fins 2 to form a threaded aluminum rolled finned pipe. The technology of the invention is mainly used in the heat exchange process in which the fluid inside the tube is liquid and the fluid outside the tube is gas. The protrusion formed by rolling in the tube effectively destroys the boundary laminar flow, making the fluid appear as turbulent flow in any area in the tube, which obviously improves the heat exchange efficiency. The overall aluminum-rolled finned tube is set outside the tube, which expands the contact area between the fluid outside the tube and the heat exchange...

Embodiment 2

[0018] Embodiment 2: An enhanced heat transfer element, including a light pipe 1, such as figure 2 As shown: the light pipe 1 is sheathed with an integral aluminum-rolled finned pipe 2; the light pipe 1 is processed into a continuous internal thread.

[0019] Such as figure 2 As shown, the technical solution adopted by the technology of the present invention to solve its technical problems is: use the bare pipe 1 as the base pipe, process continuous internal threads in the pipe 1 to make an internally threaded pipe, add aluminum rolled fins 2 outside the pipe, Formed internally threaded aluminum rolled finned tubes. The technology of the invention is mainly used in the heat exchange process in which the fluid inside the tube is liquid and the fluid outside the tube is gas. The continuous thread in the tube effectively destroys the boundary laminar flow, making the fluid appear as turbulent flow in any area in the tube, which obviously improves the heat exchange efficiency....

Abstract

The invention relates to a heat transferring element, in particular to a reinforced heat transferring element. The reinforced heat transferring element comprises a light tube and is characterized in that the light tube is sleeved with an integral aluminum rolling finned tube. The reinforced heat transferring element is unique in structure, not only can break boundary layer flow of fluid in the tube, but also increases the area of the outer surface of a heat exchange tube, and heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to a heat transfer element, in particular to an enhanced heat transfer element. Background technique [0002] In addition to light tubes, the commonly used forms of enhanced heat transfer tubes include finned tubes, threaded tubes, that is, integral low-finned tubes, spiral grooved tubes, corrugated tubes, that is, corrugated tubes, etc. Among them, the finned tube and the threaded tube add fins or threads on the outer surface of the bare tube to increase the outer surface area of ​​the heat exchange tube, thereby improving the heat exchange efficiency, but because the inner wall of the tube is still a smooth tube, it does not destroy the fluid in the tube. Although the spiral grooved tube and corrugated tube destroy the boundary laminar flow of the fluid in the tube to improve the heat exchange efficiency, they have no obvious impact on the outer surface area of ​​the heat exchange tube. Therefore, although finned tubes, threade...
