Abstract
The utility model provides a solar absorbing plate core capable of preventing electrochemical corrosion, which comprises a copper pipe and an aluminum plate welded on the copper pipe, wherein insulation rubber is coated at the periphery of a position where the copper pipe is welded with the aluminum plate. The solar absorbing plate core has the effect of moist air isolating by coating the insulation rubber at the periphery of the position where the copper pipe is welded with the aluminum plate, effectively prevents the electrochemical corrosion formed between the copper pipe and the aluminum plate, and guarantees the quality and the service life.
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 that glue-line is isolated in coating around described copper pipe and the aluminium sheet weld.
Further, described isolation glue-line is the high temperature resistant isolation glue-line of keeping apart copper pipe 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 coated on around the weld of copper pipe and aluminium sheet by the isolation glue-line, play the effect of isolating humid air, 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, copper pipe 1 is coated with high temperature resistant glue-line 3 with around aluminium sheet 2 welds, keep apart copper pipe 1 and aluminium sheet 2(promptly by high temperature resistant glue-line 3, except weld, copper pipe 1 and aluminium sheet 2 are kept apart by high temperature resistant glue-line 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 potential difference, thereby avoided the generation of electrochemical reaction, made 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.High temperature resistant glue-line 3 also can adopt other isolation glue-lines that are fit to substitute.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 (3)
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, glue-line is isolated in coating around described copper pipe and the aluminium sheet weld.
