Abstract
The invention discloses a tube plate type fin of an air cooler, which comprises a body, wherein a plurality of tube holes which are arranged in an array mode are arranged on the body; the body is made of pure copper; a bead is arranged at each pipe hole, and the end part of each bead is provided with an expansion port; a circular diversion trench and four arc diversion sheets are arranged around each pipe hole, the four arc diversion sheets are uniformly arranged around each pipe hole along the circumference, and each arc diversion sheet spans over the diversion trench; a linear flow deflector is arranged between the upper and lower adjacent pipe holes; the arc-shaped flow deflector is in a structure like a Chinese character ji, and the linear flow deflector is in an isosceles trapezoid structure; the pipe holes in two adjacent rows on the body are arranged in a staggered manner; the invention has simple structure and ingenious design, and the heat exchange area of the air-cooled air cooler is effectively increased and the heat exchange efficiency is greatly improved by adopting the pure copper with good heat conduction effect to manufacture the fins and improving the structure of the fins.
Description
Technical Field
The invention relates to the technical field of heat exchange equipment, in particular to a tube plate type fin of an air cooler.
Background
At present, the air cooler is as the heat exchange equipment who commonly uses, is equipped with tube sheet formula fin in the air cooler, and this kind of fin simple structure when high-pressure air passes through the fin, can not contact with the fin fully and carry out better heat exchange to lead to its heat exchange efficiency low.
Disclosure of Invention
The invention aims to solve the problems of simple structure and low heat exchange efficiency of a tube plate type fin in the existing air cooler, and provides the tube plate type fin of the air cooler.
The specific scheme of the invention is as follows: a tube plate type fin of an air cooler is provided with a body, wherein a plurality of tube holes which are arranged in an array mode are formed in the body; the body is made of pure copper; a bead is arranged at each pipe hole, an expansion port is arranged at the end part of the bead, a circular guide groove and four arc-shaped guide vanes are arranged around each pipe hole, the four arc-shaped guide vanes are uniformly arranged around each pipe hole along the circumference, and each arc-shaped guide vane crosses over the guide groove; a linear flow deflector is arranged between the upper and lower adjacent pipe holes; the arc-shaped flow deflector is in a structure like a Chinese character ji, and the linear flow deflector is in an isosceles trapezoid structure; the pipe holes of two adjacent columns on the body are arranged in a staggered way.
In the invention, four rows of pipe holes are arranged on the body; the left end and the right end of the body are both designed to be in a sawtooth structure.
The invention has simple structure and ingenious design, and the heat exchange area of the air-cooled air cooler is effectively increased and the heat exchange efficiency is greatly improved by adopting the pure copper with good heat conduction effect to manufacture the fins and improving the structure of the fins.
Drawings
FIG. 1 is a schematic top view of the present invention;
FIG. 2 is a view A-A of FIG. 2;
fig. 3 is a view B-B of fig. 2.
In the figure: the structure comprises a body, 2 pipe holes, 3 edge openings, 4 expansion ports, 5 flow guide grooves, 6 arc-shaped flow guide sheets, 7 linear flow guide sheets and 8 sawtooth-shaped structures.
Detailed Description
Referring to fig. 1-3, an air cooler tube plate type fin has a body 1, on which a plurality of tube holes 2 arranged in an array are arranged; the body 1 is made of pure copper; a bead 3 is arranged at each pipe hole 2, an expansion port 4 is arranged at the end part of the bead 3, a circular guide groove 5 and four arc-shaped guide vanes 6 are arranged around each pipe hole 2, the four arc-shaped guide vanes 6 are uniformly arranged around each pipe hole 2 along the circumference, and each arc-shaped guide vane 6 spans over the guide groove 5; a linear flow deflector 7 is arranged between the two pipe holes 2 which are adjacent to each other; the arc-shaped flow deflector 6 is in a structure like a Chinese character ji, and the linear flow deflector 7 is in an isosceles trapezoid structure; two adjacent rows of pipe holes 2 on the body 1 are arranged in a staggered way.
In this embodiment, four rows of pipe holes 2 are arranged on the body 1; the left and right ends of the body are both designed into sawtooth structures 8.
