Elliptical finned tube type heat exchanger and elliptical finned tube type intelligent phase-change heat exchange device

Abstract

The invention provides an oval finned tube type heat exchanger and an oval finned tube type intelligent phase-change heat exchange device, and belongs to the technical field of heat exchangers. The oval finned tube type heat exchanger and the oval finned tube type intelligent phase-change heat exchange device comprise a heat exchange barrel, and a heat exchange mechanism is arranged in the heat exchange barrel; the heat exchange mechanism is composed of an oval finned tube, an inlet connector structure and an outlet connector structure, the inlet connector structure and the outlet connector structure are connected to the head end and the tail end of the oval finned tube, the heat exchange barrel is communicated with a smoke inlet structure and a smoke outlet structure, and the whole oval finned tube type heat exchanger is reasonable in structural arrangement, ingenious in conception and flexible to use. Compact arrangement of the oval finned tubes is easier to achieve, the overall size of the whole heat exchanger is reduced in cooperation with spiral distribution of the whole oval finned tubes, and therefore the occupied area is reduced, the smoke flushing convenience in the heat exchanger for smoke in a heat exchange barrel is improved through a smoke flushing mechanism in the device, the use and maintenance cost of the device is reduced, and the service life of the device is prolonged. And the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to an elliptical fin tube heat exchanger and an elliptical fin tube intelligent phase-change heat device. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . In the flue at the tail of the boiler, there is generally a finned tube heat exchanger for absorbing the waste heat of the flue gas. [0003] However, after a long period of use, the heat exchangers in the prior art tend to accumulate dust in the triangular rear part of the circular finned tubes, thereby affecting the heat exchange efficiency of the finned tubes, and ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an elliptical finned tube heat exchanger and an elliptical finned tube type intelligent phase-change heat device, aiming at solving the problem that the heat exchanger in the prior art is easy to lose The triangular ash accumulation area at the rear of the finned tube affects the heat transfer efficiency of the finned tube, and the common circular finned tube exists, the air side resistance is large, and the heat transfer coefficient between the fluids is reduced; the thermal resistance inside the tube is relatively large , reducing the heat transfer capacity of the fluid in the tube, and it is troublesome to clean the soot on the finned tubes in the heat exchanger, etc.
