Abstract
The utility model provides a solar energy heat absorbing plate core capable of preventing electrochemical corrosion, which comprises a copper pipe, an aluminum plate, and an aluminum film layer coated on the surface of the copper pipe, wherein the copper pipe and the aluminum plate are welded and fixed with each other through the aluminum film layer. For the solar energy heat absorbing plate core capable of preventing electrochemical corrosion, by coating the aluminum film layer on the surface of the copper pipe, aluminum-aluminum contact is formed at a welding part with same potential difference, so as to avoid electrochemical reaction, effectively prevent electrochemical corrosion between the copper pipe and the aluminum plate, and ensure the quality and service life of the solar energy heat absorbing plate core.
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 aluminium sheet, and the aluminum membranous layer that is coated on copper pipe surface, and described copper pipe is welded to each other fixing by aluminum membranous layer and aluminium sheet.
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 being coated with aluminum membranous layer in copper pipe surface, make the welding position be the contact of aluminium aluminium, potential difference is identical, therefore can not produce electrochemical reaction, 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 aluminum membranous layer 3 that the solar absorber plate core that can prevent electrochemical corrosion that the utility model preferred embodiment provides comprises copper pipe 1 and is coated on copper pipe 1 surface, described copper pipe 1 carry out ultrasonic bonding by aluminum membranous layer 3 and aluminium sheet 2 to be fixed.In the manufacturing process, can adopt arc-spraying machine at copper pipe 1 surface spraying layer of aluminum rete 3.Because the welding position is the contact of aluminium aluminium, potential difference is identical, therefore can not produce electrochemical reaction, 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, makes 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 aluminium sheet, it is characterized in that, further comprises the aluminum membranous layer that is coated on copper pipe surface, and described copper pipe is welded to each other fixing by aluminum membranous layer and aluminium sheet.
