Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger with a non-metallic heat conducting pipe. Background Art

[0002] In the presence of some highly corrosive media, such as low-concentration sulfuric acid and heat exchangers containing solutions with high chloride ion concentrations, corrosion-resistant precious metals such as titanium, nickel-based alloys, zirconium, etc. are used in large quantities due to corrosion. These materials have excellent corrosion resistance, but are extremely expensive, which limits their application. Non-metallic heat exchange tubes have been widely used due to their excellent corrosion resistance and low prices. When transporting and exchanging media, they can also provide appropriate assistance to promote transportation, thereby increasing heat exchange efficiency.

[0003] In the existing patent application number CN205049020U, a heat exchanger with a non-metallic heat exchange tube bundle is disclosed, including a front tube box, a rear tube box, a non-metallic heat exchange tube bundle, and a shell. The non-metallic heat exchange tube bundle is installed in the shell, and a support is provided at the lower part. The shell is provided with a second fluid outlet and a second fluid inlet, and the two ends are respectively connected to the front tube box and the rear tube box through flanges. The front tube plate of the non-metallic heat exchange tube bundle is clamped by the flange connected to one end of the aforementioned shell and the front tube box, and a sealing gasket is placed between the contact surfaces. The two ends of the rear tube plate are pressed against the inner wall of the shell. A partition is provided in the front tube box, and the first fluid inlet is provided on the upper part and the first fluid outlet is provided on the lower part. This heat exchanger uses non-metallic heat-conducting pipes to increase the service life, but the medium transportation is not assisted, the heat exchange efficiency is not high, and the practicality needs to be improved.

[0004] Therefore, it is necessary to design a heat exchanger with non-metallic heat pipes that is highly practical and structurally stable. Utility Model Content

After the shell side medium completes the heat exchange, it is discharged from the lower shell side outlet of the cylinder. Two sets of fan assemblies in different directions are operated simultaneously by a driving motor to assist the transportation of the tube side medium and the shell side medium, which greatly increases the heat exchange efficiency and improves the work efficiency.

[0011] (2) The baffles are provided to increase the contact time between the shell-side medium and the non-metallic heat pipe from entry to exit, so that the medium is transmitted up and down through the baffles like an electric wave, and finally discharged through the shell-side outlet.
