Abstract
A novel aluminum wing for a U-tube solar thermal collector includes an outer wall of the aluminum wing, a U-tube flow channel groove 1 and a U-tube flow channel groove 2 which are made from a whole aluminum sheet in a folded shape. The outer wall of the aluminum wing is contacted with an inner pipe of an evacuated glass tube and is used for heat exchange with solar-energy heat absorbed by a selective coating on the evacuated glass tube. Two U-tube flow channel grooves wrap a U-shaped copper tube, so that a maximizing contact area between the aluminum wing and the outer surface of the U-shaped copper tube is realized. The heat is transferred into the water in the U-shaped copper tube by heat conduction, thereby completing the working process of solar thermal absorption of the collector tube.
Description
Technical field
The utility model relates to a kind of solar energy collecting tubes aluminium wing, mainly is to improve heat exchanger effectiveness by enlarging heat transfer area, belongs to technical field of solar utilization technique.
Background technology
New forms of energy are one of five big technical fields of tool decision power in the 21st century development of world economy.Solar energy is a kind of cleaning, efficiently and never depleted new forms of energy, and solar water heater is a kind of in the solar utilization technique, and to be the energy that utilizes the sun be heated to the device of high-temperature with water from low temperature for it, is a kind of heat energy product.At present, the kind of solar water heater is a lot, and wherein, heat is more to pass quickly in order to allow, and can use heat pipe, U type pipe equal vacuum thermal-collecting tube.U type pipe heat collector is to insert the metal tube that curves the U type in all-glass vacuum tube.Between U type metal tube and all-glass vacuum tube, the aluminium wing that all closely contacts with both is arranged equally, Fig. 3 is the cutaway view of the prior art aluminium wing, it has comprised aluminium wing outer wall 4, U type pipe flow path groove 5, undertakes the conduction of heat between glass tube with vacuum and the U type copper pipe.Be heated fluid and in metal tube, flow through, absorb the solar radiation heat that all-glass vacuum tube collects and be heated, thereby constitute U type pipe-solar vacuum tube collector.Since anhydrous in the vacuum tube, meet vacuum tube and break, and heat collector can use as usual.And the interior aluminium wing of employed in the market U type pipe has as shown in Figure 3 just wrapped up half root of U type copper pipe, half root copper pipe in addition is not with the contact of the aluminium wing, thereby cause the heat exchange area of the aluminium wing and U type copper pipe less than normal, the solar heat that makes thermal-collecting tube absorb can not in time exchange to U type copper pipe to be taken away, both exchange heat speed and exchange capacity are all very low, reduce heat transfer property, caused efficient on the low side, influenced the overall performance of solar water heating system.
Summary of the invention
The purpose of this utility model provides a kind of novel aluminum wing of the U of being applicable to type tube solar heat-collecting device.
Problem to be solved in the utility model is the deficiency that heat exchange area is less than normal, heat exchange efficiency is low between the existing U type pipe aluminium wing and U type pipe.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
The utility model proposes a kind of aluminium wing of brand-new U type tube solar heat-collecting device, comprise: aluminium wing outer wall, U type pipe flow path groove one and U type pipe flow path groove two, aluminium wing outer wall, U type pipe flow path groove one and U type pipe flow path groove two are formed by the folding typing of whole aluminium flake, and the interior pipe of aluminium wing outer wall and glass tube with vacuum contacts.
The total U type pipe flow path groove one of the aluminium wing and 2 two flow path grooves of U type pipe flow path groove; The thickness of aluminium wing outer wall, U type pipe flow path groove one and U type pipe flow path groove two is 1-3mm.
Aluminium wing outer wall is that the interior pipe with glass tube with vacuum contacts, and carries out exchange heat with the solar heat that selective coating on the glass tube with vacuum absorbs; Two U type pipe flow path grooves realize that the aluminium wing contact with the maximization of U type copper pipe outer surface to U type copper pipe parcel, conduct in the water of exchange heat in the U type copper pipe by heat, thereby finish the workflow of thermal-collecting tube absorption solar energy.
The utility model has the advantages that: this aluminium wing is identical with the installation site of the general aluminium wing.Because the area that has only half root copper pipe that the general aluminium wing contacts with U type copper pipe, the design has used two U type pipe flow path grooves, can closely contact with whole U type pipe, realize whole U type copper pipe of an aluminium wing parcel, allow heat can pass to copper pipe more, increase heat exchange area, improved the efficient of heat collector greatly.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Shown in Fig. 1-2, the utility model has comprised aluminium wing outer wall 1, U type pipe flow path groove 1 and U type pipe flow path groove 23, and aluminium wing outer wall 1, U type pipe flow path groove 1 and U type pipe flow path groove 23 are formed by the folding typing of whole aluminium flake, and the thickness of the whole aluminium wing is 2mm; Aluminium wing outer wall 1 is that the interior pipe with glass tube with vacuum contacts, and carries out exchange heat with the solar heat that selective coating on the glass tube with vacuum absorbs; U type pipe flow path groove 1 and U type pipe flow path groove 23 wrap up U type copper pipe, realize that the aluminium wing contacts with the maximization of U type copper pipe outer surface, by heat conduction in the water of exchange heat in the U type copper pipe, thereby finish solar heat from thermal-collecting tube to the aluminium wing again to the transfer flow of U type pipe.
