Abstract
The utility model relates to a u-shaped tube type solar vacuum heat collecting tube, which comprises a glass tube, a metal u-shaped tube and a metal end cap. The utility model is characterized in that the u-shaped tube type solar vacuum heat collecting tube also comprises a metal heat absorbing plate. A selective absorption coating is coated on the surface of the metal heat absorbing plate which is inserted into the glass tube. The u-shaped tube is fixed to the heat absorbing plate. Both open ends of the u-shaped tube are connected to the end cap. The open end of the glass tube is provided with a glass flange and is fixedly connected with the end cap through glass-metal hot-press sealing technology. The utility model is characterized in that a working medium in the u-shaped tube is heated through metal and metal heat conduction. Thus, the heat performance of the vacuum heat collecting tube is greatly enhanced. The u-shaped tube type solar vacuum heat collecting tube can be widely used in various solar vacuum heat collecting devices.
Description
The utility model relates to a kind of solar vacuum heat-collecting pipe.
Existing U type tubular solar energy evacuated heat-collecting tube is the improvement of carrying out on the basis of all-glass vacuum thermal-collecting tube, and it is made up of inside and outside layer glass pipe, and the absorber of vacuum heat collection pipe is a glass inner tube.In glass inner tube, insert one and the close-connected U type of cylindrical metal plate metal tube, and metallic plate is abutted against on the inner surface of glass inner tube, make glass inner tube absorb the heat energy that converts to after the solar radiation and can pass to metallic plate, with the working medium in the heating U type metal tube pipe.Though this vacuum heat collection pipe can overcome the shortcoming that all-glass vacuum thermal-collecting tube can not pressure-bearing, because heat transmission is to be undertaken by metallic plate and contacting of glass inner tube, its thermal contact resistance is bigger, thereby has reduced the hot property of vacuum heat collection pipe significantly.
The purpose of this utility model provides a kind of U type tubular solar energy evacuated heat-collecting tube that can obviously improve hot property.
For achieving the above object, the utility model is taked following design: a kind of U type tubular solar energy evacuated heat-collecting tube, it comprises glass tube, metal U type pipe, metal end, it is characterized in that: it also comprises a metal absorber plate, the surface of described absorber plate is coated with coating for selective absorption, it is plugged in the described glass tube, described U type pipe is fixed on the described absorber plate, and its two openend is connected on the described end cap, and the openend of described glass tube has the glass flange, and is fixed together by glass-metal hot-press sealing technology with described end cap.
The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to removed glass inner tube, scribble the metallic plate of coating for selective absorption as absorber plate and adopt, and U type pipe is fixed on the absorber plate, therefore the heat that absorber plate can be absorbed directly conducts the working medium that heats in the U type pipe by the heat between metal and the metal, thereby the hot property of vacuum heat collection pipe is greatly improved.2, the utility model is owing to adopt glass-metal hot-press sealing technology that glass tube is connected with metal end, thereby can guarantee the vacuum seal requirement in the glass tube, makes the metallic plate that is connected with U type pipe become possibility as absorber plate.The utility model is simple in structure, connects reliably, and the hot property height, it can be widely used in the various solar energy heat collectors.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model structural representation
Fig. 2 is the schematic side view of Fig. 1
As shown in Figure 1 and Figure 2, the utility model comprises a glass tube 1, and its openend has glass flange 2.One metal absorber plate 3, its surface all is coated with coating for selective absorption.On metal absorber plate 3, weld or rivet or be crimped with a metal U type pipe 4.One metal end 5 has two through hole 6 on it, the entrance point of U type pipe 4 and the port of export are passed through hole 6 on the end cap 5 respectively, and with end cap 5 seal weldings.Absorber plate 3 is inserted in the glass tubes 1 together with U type pipe 4, and use various conventional chucking modes (as with metal clamps etc.), absorber plate 3 is not rocked in glass tube 1.Adopt hot-pressing process for glass-metal sealing (see also the patent No. be 93101627.4 " hot press sealing process ") then, glass tube 1 and end cap 5 are tightly connected to become one.At last, adopt conventional method that glass tube 1 is carried out vacuum exhaust, make it reach predetermined vacuum state.
During use, the entrance end of U type pipe 4 is connected by the serial or parallel connection mode with the entrance end of the U type pipe 4 of adjacent vacuum heat collection pipe respectively, and finally is connected with the entrance end of heating system working medium circulation duct.When shining upon on this solar vacuum heat-collecting pipe, absorber plate absorbs solar radiant energy, converts it into heat energy, and directly heating flows into from U type pipe 4 one ends, the working medium of other end outflow, thus greatly improved the hot property of vacuum heat collection pipe.
In the foregoing description, the shape of absorber plate 3 can be plate shaped, also can be semicircular arc etc.
