Embodiment Construction
[0010] Such as figure 1 As shown, in the embodiment 1 of an industrial high-efficiency pipe of the present invention, a plurality of dimples 11 are radially stamped outside the pipe body 1, and three dimples 11 are evenly distributed on the circumference of any cross-section of the pipe body 1. The dimples 11 on two adjacent cross-sections have a circumferential difference of 60°.
[0011] Such as figure 2 As shown, in the embodiment 2 of an industrial high-efficiency pipe of the present invention, several dimples 21 are punched radially outside the pipe body 2, and two dimples 21 are evenly distributed on the circumference of any cross-section of the pipe body 2, and any phase in the axial direction The dimples 21 on two adjacent cross-sections are axially different by 90°.

The invention relates to an industrial efficient pipe for the field of engineering materials, in particular to an industrial efficient pipe for improving the heat transfer efficiency in the field of heat exchangers, and solves the problem of low heat exchange efficiency of heat exchange pipes. According to the technical scheme, the industrial efficient pipe comprises a pipe body and is structurally characterized in that the pipe body is a round pipe, a plurality of pits are radially punched in the outer part of the pipe body, the pits in any cross section are uniformly formed in the circumferential direction, and any two adjacent pits in the axial direction are staggered by a certain circumferential angle; and after the pits are punched in the outer part of the pipe body, the pipe wall of the pipe body is equal in thickness, and the resilience value of the pits in the pipe body does not exceed 10%. The heat exchange area of the pipe is remarkably larger than those of existing round heat exchange pipes, so that the heat exchange efficiency can be effectively improved; and scaling does not occur in the pipe easily, thus the scaling maintenance cost is reduced.
Description
technical field [0001] The invention relates to an industrial high-efficiency tube used in the field of engineering materials, in particular to an industrial high-efficiency tube used in the field of heat exchangers to improve heat transfer efficiency. Background technique [0002] In the field of commonly used mechanical engineering materials, there are many kinds of steel pipe materials, including welded pipes for fluid conveyance, electric welded steel pipes for transmission shafts, seamless steel pipes for structural and fluid conveyance, cold drawn or cold rolled precision seamless steel pipes, etc., general fluid conveying welding Steel pipes are used to convey low-pressure fluids such as water, sewage, gas, and air heating, while structural seamless steel pipes are mainly used for machinery, automobiles, bicycles, furniture, hotel and restaurant decoration, and other mechanical parts and structural parts. [0003] The types of heat exchange tubes used in the field of ...
