Problems solved by technology

The performance of the heat exchanger largely depends on the performance of the heat exchange tubes. The heat exchange tubes in the prior art mostly use ordinary smooth tubes. The effective heat exchange area of ​​this kind of heat exchanger is small, which leads to the The heat transfer efficiency of the heat pipe is low, which limits its application in the market and cannot meet the needs of today's customers. Therefore, it is necessary to propose a new type of seamless tube for boiler heat exchangers

Abstract

The invention discloses a novel seamless tube for a boiler heat exchanger. The seamless tube comprises a seamless tube body, a first inner fin, a second inner fin, a first outer fin, a second outer fin and a third outer fin. Compared with the prior art, the seamless tube is simple in structure and reasonable in design; the heat conduction fins are arranged on the outer wall of the seamless tube, so that the heat exchange area is increased; the heat conduction fins arranged on the inner wall of the seamless tube not only have the heat conduction function, but also have the effect of slowing down the flow rate of hot medium, so that the heat conduction is more sufficient; and the seamless tube adopts stainless steel design, so that the corrosion resistance is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of boiler heat exchange, in particular to a novel seamless tube for boiler heat exchangers. [0003] 【Background technique】 [0004] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy, and the heat carrier realizes heat energy in two media through a heat exchanger. Among them, the heat exchange tube is one of the components of the heat exchanger, which is placed in the cylinder and used for the exchange of heat between the two media. With the development of refrigeration, metallurgy, machinery, boiler manufacturing and other industrial technologies With continuous improvement, the requirements for heat exchangers have also increased accordingly. The performance of the heat exchanger largely depends on the performance of...
