Abstract

The utility model belongs to heat exchanger technical field, is a kind of heat exchanger fin, has substrate, and the equally distributed through-hole of several columns is stamped on substrate, and adjacent two row through-hole dislocation is arranged, especially:There are one strip louvres for punching press between the adjacent two through hole of same row on the substrate, around each through-hole, through-hole surrounding punching press there are four equally distributed rectangular heat emission hole, the strip louvre is parallel with the long side direction of fin, the rectangular heat emission hole is located at 45 degree of each through-hole, 45 degree, 135 degree, 225 degree of angular direction, and two long sides of the fin are processed as laciniation;The utility model is simple in structure, and heat transfer efficiency is high, easy to process, is suitable for various tubular heat exchangers and uses.

Description

A kind of heat exchanger fin
Technical field
The utility model is related to heat exchanger technical field, specifically a kind of heat exchanger fin.
Background technology
Tubular heat exchanger is a kind of heat exchanger most widely used in current Chemical Manufacture.It mainly by shell, tube sheet, change The compositions such as heat pipe, end socket, hydraulic barrier are also set with radiating fin to improve heat exchange efficiency on heat exchanger tube, general at present Radiation fin structure it is simple, be only machined with according to the size and arrangement of heat exchanger tube on copper material or aluminium material substrate logical Hole, radiating efficiency is not high, or even can influence the flow velocity of shell side medium to a certain extent.Therefore, a kind of novel change is researched and developed Hot device fin structure, it is very necessary for improving efficiency of heat exchanger.
Invention content
The purpose of this utility model is simple aiming at current heat exchanger fin structure, the not high problem of heat exchange efficiency, A kind of heat exchanger fin is provided.
The technical solution of the utility model is:A kind of heat exchanger fin has substrate, it is equal that several columns is stamped on substrate The through-hole of even distribution, adjacent two row through-hole dislocation arrangement, especially:It is stamped between the adjacent two through hole of same row on the substrate One strip louvre surrounds each through-hole, through-hole surrounding punching press there are four equally distributed rectangular heat emission hole, institute State that strip louvre is parallel with the long side direction of fin, the rectangular heat emission hole is located at -45 degree of each through-hole, 45 Degree, 135 degree, 225 degree of angular direction, two long sides of the fin are processed as laciniation.
The material of substrate described in the utility model is aluminium alloy or copper alloy or fine copper material.
On each through-hole of substrate the same side described in the utility model a circle boss is stamped with also along through-hole perimeter.
The heat exchanger fin structure of the utility model is simple, easy to use, and when installation, which is sleeved on heat exchanger tube, to be arranged It is good, in use, due to being stamped with strip louvre and rectangular heat emission hole around through-hole, and in two long sides of fin On be machined with laciniation, can greatly improve the heat exchange efficiency of heat exchanger, various heat exchangers is suitble to use.
The utility model is simple in structure, and heat transfer efficiency is high, easy to process, is suitable for various tubular heat exchangers and uses, tool There is very high economic benefit.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model;
In figure, 1-substrate, 2-through-holes, 3-strip louvres, 4-rectangular heat emission holes, 5-laciniations, 6- Boss.
Specific implementation mode
Embodiment 1
Referring to Fig. 1, the technical solution of the utility model is:A kind of heat exchanger fin has substrate 1, the punching press on substrate There are the equally distributed through-hole 2 of several columns, adjacent two row through-hole dislocation to arrange, especially:Same row adjacent two is led on the substrate 1 There are one strip louvres 3 for punching press between hole, surround each through-hole 2, and in the surrounding punching press of through-hole, there are four be uniformly distributed Rectangular heat emission hole 4, the strip louvre 3 is parallel with the long side direction of fin, and the rectangular heat emission hole 4 is located at often - 45 degree of a through-hole, 45 degree, 135 degree, 225 degree of angular direction, two long sides of the fin are processed as laciniation 5.
The material of substrate 1 described in the present embodiment is aluminium alloy or copper alloy or fine copper material.
On each through-hole of substrate the same side described in the present embodiment a circle boss 6 is stamped with also along through-hole perimeter.
