Abstract
The invention discloses an antimicrobial corrosion-resistant heat exchanger copper tube which is composed of the following raw materials: 1-2 parts of antimony, 2-3 parts of silicon, 1-2 parts of arsenium, 2-4 parts of zirconium, 1-2 parts of yttrium, 2-3 parts of barium, 3-5 parts of iron, 2-3 parts of cobalt, 2-3 parts of boron, 80-100 parts of copper and inevitable impurities. The antimicrobial corrosion-resistant heat exchanger copper tube has the advantages of enough corrosion resistance, favorable antibacterial effect, higher tensile strength, higher elongation percentage and higher heat resistance, and inhibits the crystal grains from becoming coarse.
Description
Technical field
The present invention relates to the technical field of the copper pipe that heat exchanger uses, particularly relate to a kind of heat-exchanger brass pipe with antibacterial and corrosion-resistant effect.
Background technology
Being generally used for fin tube heat exchanger is U-shaped copper pipe bending machining being become thin effect shape, has aluminum or aluminum alloy plate to form the communicating pores of radiator element, is inserted by expanding tool in copper pipe and carry out expander to copper pipe, makes copper pipe and aluminium radiator fin sealing.In addition, expander is carried out to the open end of copper pipe, bending machining is become the bending copper pipe of U-shaped to insert this expander open end, with solders such as phosphor-coppers, bending copper pipe is brazed in the expander open end of U-shaped copper pipe, connect multiple U-shaped copper pipe by bending copper pipe, make heat exchanger.
Also can durablely use even if the wall thickness in order to the phosphorous deoxidize copper tube being used in fin-and-tube type interchanger is thinning, by carrying out the plastic workings such as drawing to improve its tensile strength to the phosphorous deoxidize copper tube after annealing, but because plastic working causes ductility to reduce, thus can not bending machining be carried out.Although have phosphide by CO in prior art to improve tensile strength, in the ratio that intensity rises, the resistance to intensity that crushes does not rise.In addition, during due to heat-transfer pipe, existence can not thinning wall thickness, thus can not get the ideal effect expected.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, a kind of antibacterial corrosion resistant heat-exchanger brass pipe is provided, this antibacterial corrosion resistant heat-exchanger brass pipe has sufficiently high corrosion resistance nature, also there is antibacterial effect, have and improve tensile strength, unit elongation and resistance to thermalization, suppress the effect of the coarsening of crystal grain.
The technical solution adopted for the present invention to solve the technical problems is: a kind of antibacterial corrosion resistant heat-exchanger brass pipe, is made up of the feed composition of following number: 1-2 part antimony, 2-3 part silicon, 1-2 part arsenic, 2-4 part zirconium, 1-2 part yttrium, 2-3 part barium, 3-5 part iron, 2-3 part cobalt, 2-3 part boron, 80-100 part copper and inevitable impurity.
Further, the number of each feed composition is: 1 part of antimony, 2 parts of silicon, 1 part of arsenic, 2 parts of zirconiums, 1 part of yttrium, 2 parts of barium, 3 parts of iron, 2 parts of cobalts, 2 parts of boron, 80 parts of copper and inevitable impurity.
Or the number of each feed composition is: 2 parts of antimony, 3 parts of silicon, 2 parts of arsenic, 4 parts of zirconiums, 2 parts of yttriums, 3 parts of barium, 5 parts of iron, 3 parts of cobalts, 3 parts of boron, 100 parts of copper and inevitable impurity.
In sum, antibacterial corrosion resistant heat-exchanger brass pipe of the present invention has sufficiently high corrosion resistance nature, also has antibacterial effect, has and improves tensile strength, unit elongation and resistance to thermalization, suppresses the effect of the coarsening of crystal grain.
