Abstract
The utility model provides a solar absorber plate core capable of preventing electrochemical corrosion, which comprises a copper tube and an aluminum plate welded on the copper tube. The surface of the aluminum plate contacted with the copper tube is coated with a copper film layer. Since the aluminum plate of the solar absorber plate core capable of preventing the electrochemical corrosion is coated with the copper film layer, the potential difference of copper-aluminum contact parts can be eliminated, the electrochemical corrosion between the copper tube and the aluminum plate can be effectively prevented, and the quality and the service life of the solar absorber plate core can be guaranteed.
Description
Technical field
The utility model relates to field of solar energy, relates in particular to a kind of evolutionary approach of solar absorber plate core.
Background technology
The utilization of solar energy has become of energy field and has given priority to direction.The critical component of common flat-plate solar collector is a heat-absorbing plate core, and the performance of heat-absorbing plate core has determined the quality of solar thermal collector to a great extent.Heat-absorbing plate core generally is made up of the fin and the tubing of copper or aluminium material, adopts ultrasonic bonding, laser weld to form usually, or adopts process for machining inflation and mechanical press to form.Because the price of copper is higher, generally speaking the heat-absorbing plate core of copper aluminium ultrasonic bonding is to make heat pipe with copper pipe, and aluminium sheet or aluminum strip band are as the heat absorption fin, both are integrally welded by supersonic welder, this heat-absorbing plate core can be so that the pressure-bearing property of solar thermal collector be better, and moderate, therefore obtain extensive approval and a large amount of use in market.Yet,, cause constantly corrosion and coming off of aluminium sheet because two kinds of different metals of copper and aluminium can meet humid air or steam and then produce electrochemical reaction at copper aluminium binding site.Simultaneously, solar thermal collector poorly sealed invaded airborne wet steam or rainwater, can produce a large amount of high hot water vapor in the cavity, causes the aluminium sheet corrosion of heat-absorbing plate core and finally causes solar thermal collector to damage and ineffective.
Therefore, existing solar absorber plate core needs to improve.
Summary of the invention
The purpose of this utility model provides a kind of solar absorber plate core that can prevent electrochemical corrosion, is intended to solve the technological deficiency that aluminium sheet that existing solar absorber plate exists is corroded easily.
For realizing above-mentioned utility model purpose, the solar absorber plate core that can prevent electrochemical corrosion that the utility model provides comprises copper pipe and is welded in aluminium sheet on the copper pipe, the surface that contacts with copper pipe on described aluminium sheet coating layer of copper metallic diaphragm.
Further, described aluminium sheet is fin or made of one piece aluminium sheet.
Than prior art, the solar absorber plate core that can prevent electrochemical corrosion that the utility model provides is by coating copper metallic diaphragm on aluminium sheet, effectively stop the electrochemical corrosion between copper pipe and the aluminium sheet, guaranteed the quality and the service life of solar absorber plate core.
Description of drawings
Fig. 1 is the structural representation that the utility model can prevent the solar absorber plate core of electrochemical corrosion.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In conjunction with referring to shown in Fig. 1, the solar absorber plate core that can prevent electrochemical corrosion that the utility model preferred embodiment provides comprises copper pipe 1 and is welded in aluminium sheet 2 on the copper pipe 1, the surface coating layer of copper metallic diaphragm 3 that on aluminium sheet 2, contacts with copper pipe 1, make copper pipe 1 identical, and then make aluminium sheet 2 not produce electrochemical reaction with copper pipe 1 with potential difference between the copper metallic diaphragm 3.Even there is the humid air medium in the external world like this, also can't make copper pipe 1 and aluminium sheet 2 produce electrochemical reaction, make aluminium sheet can not be corroded.
The above only is preferred embodiment of the present utility model, not in order to restriction the utility model.For example, aluminium sheet 2 not necessarily is confined to shape and the form among the figure, also can adopt the form and copper pipe 1 welding of aluminium fin, and the quantity of aluminium sheet 2 etc. also can be according to the actual conditions adjustment.All any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. can prevent the solar absorber plate core of electrochemical corrosion, it comprises copper pipe and is welded in aluminium sheet on the copper pipe, it is characterized in that, the surface coating layer of copper metallic diaphragm that contacts with copper pipe on the described aluminium sheet.
