Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0025] like Figure 1 to Figure 6 As shown, according to the embodiment of the present invention, the heat transfer pipe includes two sections of heat transfer pipe joints 11 disposed at both ends of the heat transfer pipe, and two sections of heat transfer pipe joints 11 disposed between and connecting the two sections of heat transfer pipe joints The twisted tube body 12 of 11 has a twisted surface tube body structure. The two-section heat transfer pipe joint 11 and the twisted pipe body 12 may be an integrated structure, or may be formed by combining multiple sections of the pipe body. The undulating surface tube structure of the twisted tube body 12 may be a su...

Abstract

The invention provides a heat transfer pipe, and heat and mass transfer equipment having the heat transfer pipe. The heat transfer pipe comprises: two heat transfer pipe joints (11), which are respectively arranged on the two sides of the heat transfer pipe; and a twisted pipe body (12), which is arranged between the two heat transfer pipe joints (11) to connect the two heat transfer pipe joints (11) and has a twisted surface pipe structure. With the heat transfer pipe of the invention, the heat and mass transfer in an evaporation process can be strengthened, heat transfer coefficients of natural convection and forced convection inside and outside the pipe are at the same time improved, and manufacturing cost of an evaporator is reduced.

Description

technical field [0001] The present invention relates to the technical field of evaporators, and in particular, to a heat transfer tube and a heat and mass transfer device including the heat transfer tube. Background technique [0002] Energy is an important material basis for economic development and social progress, and together with materials and information constitute the three pillars of a modern society. Energy is not only the driving force for the development of the national economy, but also an indicator to measure the comprehensive national strength and people's living standards, as well as the degree of civilization and development of the country. Petroleum, chemical, power, metallurgy, refrigeration and other industries are pillar industries in my country, and they are also traditional industries with high energy consumption, and their energy consumption accounts for about 40% of the total energy consumption. In these high energy consumption industries, the heat t...
