Description
Technical field
The invention relates to conditioner, particularly be the anti-erosion device of air conditioner heat exchanger.
Background technology
Generally, window type air-conditioner is installed on the wall of buildings, be positioned at indoor indoor side heat exchanger and be positioned at outdoor outdoor heat exchanger one on the whole, therefore different with the come split wall-hanging air conditioner that is provided with and large-scale cabinet air conditioner of indoor side heat exchanger and outdoor heat exchanger branch.
As depicted in figs. 1 and 2, the such window type air-conditioner of simple declaration is as follows.
Window type air-conditioner as shown in Figure 1, in order to suck room air, one side is formed with broad suction port 2 in casing 1 front of box body shape; For to indoor discharge heat-exchanged air, opposite side is formed with relief outlet 3; In order to control conditioner, above-mentioned relief outlet 3 downsides are combined with a plurality of operation knobs 4.
As shown in Figure 2, base plate 11 upsides that are arranged on said machine casing 1 inside are provided with the indoor at a certain distance and isolate wall body 12 and outside isolation wall body 13, and the baffle plate 14 of spaced chamber inboard and outside is equipped with in the back of above-mentioned indoor isolation wall body 12, plays the effect of supporter simultaneously.
The motor base of baffle plate 14 1 sides is provided with drive-motor 16, and the end, indoor of drive-motor 16 is provided with the blowing fan 17 that makes air cycle, and end, drive-motor 16 outside is combined with cooling fan 18.
In order to make the room air heat exchange that sucks by suction port 2, the place ahead of blowing fan 17 is provided with indoor side heat exchanger 19, and the place ahead of cooling fan 18 is provided with outdoor heat exchanger 20.
Fig. 3 is an outdoor heat exchanger 20.As shown in the figure, both sides be provided with at a certain distance fixed link 21,21 ', fixed link 21,21 ' the inboard be provided with a plurality of radiator element 22, be combined with refrigerant pipe 23 with zigzag fashion on the radiator element 22.
Therefore, if drive existing window type air-conditioner as above-mentioned formation, the warm air that flow into 2 li of suction ports under the effect of blowing fan 17 is through indoor side heat exchanger 19, is discharged to indoor by relief outlet 13 after converting freezing air to.
And the outdoor heat exchanger 20 that is positioned at the outside produces heat under the effect of freeze cycle, and consequent heat is cooled, and fan 18 wind of sending are next to dispel the heat to the outside.
When being installed in many regions of rainfall amount or seashore as the existing conditioner of above-mentioned formation, the component that corrode the heat exchanger 20 of outside from the rainwater or the salt solution of external penetration.These corrode common refrigerant pipe 23 and the galvanic corrosion of contact between the radiator element 22 of the aluminum on the refrigerant pipe 23 by copper product, and aggravation is corroded fast.The aluminum radiator element 22 that particularly galvanic series is low relatively corrodes sooner, and its result reduces the performance of heat exchanger 20, and shortens its work-ing life fast.
Summary of the invention
In order to solve the problem that above-mentioned technology exists, the invention provides a kind of anti-erosion device of air conditioner heat exchanger, its objective is not allow to produce potential difference between refrigerant pipe and the radiator element, prevent by potential difference and cause the quick erosive phenomenon of component, heat exchanger is prolonged work-ing life.
To achieve these goals, the technical solution used in the present invention is: a pair of fixed link is set at a certain distance possessing, the inboard equidistant arrangement of fixed link is provided with radiator element, on radiator element, be combined with the refrigerant pipe with zigzag fashion, in order to prevent to produce galvanic corrosion between refrigerant pipe and the radiator element, on refrigerant pipe periphery, form coating with the radiator element same material.
The conditioner that possesses above-mentioned heat exchanger is connected power supply, makes the blowing fan rotation, and indoor air flow into casing inside by suction port, after the process indoor side heat exchanger converts freezing air to, is discharged to indoor again; Be positioned at the heat exchanger of outside because freeze cycle produces heat, and be cooled the wind that fan sends of consequent heat goes out and cools off.
Above-mentioned refrigerant pipe is inserted in behind the through hole on the radiator element enlarging the form assembling of conduit diameter, and the coating with the radiator element same material is arranged on the periphery as the refrigerant pipe of assembling.Coating is identical aluminum with the material of radiator element.Therefore the heat exchanger as above-mentioned setting can prevent between refrigerant pipe and the radiator element because of the quick erosive phenomenon of potential difference.
The present invention has following beneficial effect: form the coating with the radiator element same material on the refrigerant pipe periphery of heat exchanger, when assembling refrigerant pipe and radiator element, the coating of same material is contacted with radiator element, prevent the galvanic corrosion phenomenon that produces by the circuit contact between the component, prevent that component from corroding fast, prolong the work-ing life of heat exchanger thus.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: the basic structure of window type air-conditioner of the present invention is identical with illustrated existing structure among Fig. 1, Fig. 2, so here omit.Use identical symbol to describe for the position identical with existing structure.
As Fig. 4, shown in Figure 5, the heat exchanger of conditioner be provided with at a certain distance a pair of fixed link 21,21 ', fixed link 21,21 ' inboard equidistant arrangement radiator element 22 is set, in the through hole 22a on the radiator element 22, insert and be combined with refrigerant round-robin refrigerant pipe 23 with zigzag fashion.In order to prevent that refrigerant pipe 23 and radiator element 22 from producing potential difference, has on the periphery as above-mentioned bonded refrigerant pipe 23 with the identical coating 100 of radiator element 22 materials.
Both, the radiator element 22 that constitutes heat exchanger 19,20 had been aluminums, and refrigerant pipe 23 is copper pipes.So heat exchanger has the coating 100 of aluminum on the periphery of refrigerant pipe 23.
Describe in detail more, the erosion of heat exchanger 19,20 mainly is the galvanic corrosion that the interior potential difference of ionogen of two kinds of metals causes.Constitute these 3 two kinds of metals electrochemical series difference under corrosive environment of heat exchanger, wherein the erosion of the copper Cu in the heat exchanger component is the most weak, is Fe, Zn, Al successively.But, though Al corrodes than being easier to, form erosion resistant oxide film on the surface when being etched under erosion environment, shield.Therefore Fe, Zn etc. can not form form erosion resistant oxide film as Al material on heat exchanger, the erosion that caused by galvanic corrosion at first takes place, be Al, Cu successively.
Here, electrochemical series is that to want reductive tendency with hydrogen be benchmark, want various metals the reductive tendency to show by size, and want than hydrogen the big metal of reductive tendency for+current potential, than hydrogen want the little metal of reductive tendency for behind-the current potential in order arrangement come out, and-the big more easy more erosion of current potential.
Standard potential electrode in the electrochemical series 25 degree aqueous solution of the textural element of heat exchanger is as following form.
[table 1]
Therefore among the present invention, when making heat exchanger 19,20, be inserted in refrigerant pipe 23 in the through hole 22a on the radiator element 22 usually after, to enlarge the form assembling of conduit diameter.At this moment, be formed with on the periphery of refrigerant pipe 23 under the state of coating 100 of aluminum, enlarge the form fitting work of conduit diameter, so the coating 100 of the lip-deep aluminum of refrigerant pipe 23 prevents to cause erosion by potential difference between refrigerant pipe 23 and the radiator element 22 with aluminum radiator element 22 contacts of same material thus.
