Definitions
- the present invention is framed within the sector of thermosolar energy, specifically within the developments of tube solar collectors, and more specifically, it focuses on the possible location of non-evaporable getters or vacuum evacuators within this type of tube collectors.
- Getters are solid materials, alloys of different metals, capable of chemically absorbing gas molecules at their surface. They are broadly used for a variety of applications, such as in particle accelerators, vacuum tubes, inert gas purification systems, etc.
- the non-evaporable getter of the invention will be used in a vacuum tube, of those used as solar receivers.
- these receivers consist of two concentric tubes, between which the vacuum is generated.
- the inner tube, through which the heated fluid flows, is metallic and the outer tube is made from glass, usually boron-silicate.
- a bellows-type expansion compensating device is positioned between both tubes in order to allow the relative movement between the metal tube and the glass tube, thus absorbing the tensions that would be created due to the difference existing between the dilatation coefficients of both tubes, thus guaranteeing the vacuum.
- this type of tubes requires the installation of materials that detect and suppress the hydrogen molecules that could be introduced into the vacuum area. These molecules are produced due to the thermal degeneration suffered by the oil used as heat-transfer fluid that circulates through the interior of the metal tube, due to the high temperatures that it reaches. These molecules end up passing through the metal tube and entering the vacuum area, increasing thermal losses and, therefore, decreasing the efficiency of the system in a significant manner.
- non-evaporable getter designs located in different locations within the vacuum area in the developments known to date.
- One example is patent US 2007034204 A1, held by SCHOTT.
- the non-evaporable getter is arranged in an outer ring space between the expansion compensating device and the glass-metal transition element.
- the getter is protected against incident solar radiation by the glass-metal transition element and against reflected radiation by the expansion compensating device. Therefore, we have a structure that is radially composed by the metal tube, the connecting element, the expansion compensating device, the non-evaporable getter, the glass-metal transition element and the glass tube from the inside out.
- the objective of the present invention is to provide a new design to locate the non-evaporable getters of the absorption tubes so it becomes even easier to assemble than the previous one, and to continue solving all of the inconveniences described in the state of the art, even increasing the rigidity of the tube without decreasing the efficiency of the system.
- the invention consists of a new getter arrangement for a tube solar collector, as well as several modifications to the rest of the tube, mainly to its ends, according to this novel arrangement.
- the function of the non-evaporable getters should not interfere with the main purpose of the receiver tube, which is to maximize its thermal performance. Its arrangement should allow this situation without compromising its function to guarantee the correct aging of the product.
- New metal tube shape similar to the current one, but having a glass tube with a greater diameter and a defined eccentricity with respect to the metal tube depending on the optics of the collector.
- the eccentricity of the tube allows improving the optical behavior of the receiver tube because the glass tube may be used as a substrate to add a solar reconcentrator by means of partial mirroring, which is discussed below.
- the new glass tube is partially mirrored.
- the mirrored area is turned into an optical surface with tolerances that must be minimized and controlled because excessive irregularities in this optical surface could prevent the reflected rays from reaching the metal tube.
- the mirroring may be directly applied to the inner face of the glass tube or by directly mirroring the outer face of the glass tube or by adding a film or fine mirror to any of the inner or outer faces of the glass tube.
- the solar radiation reaches the metal tube in the entire perimeter.
- the flow distribution is not homogenous in the perimeter; the heat flow is greater in the perimeter that is found facing the primary reflector directly.
- the metal tube and the glass tube must always be sectioned in the same position because any relative movement could cause the escape of the rays. Since the metal tube and the glass tube have different thermal dilatation coefficients and the shape of the tubes changes, the dilatation compensation element (bellows) should allow the relative axial deformation between both tubes before the new thermal load defined in point 3, while ensuring the control of the relative movements between the metal tube and the glass tube outside their axis. A new bellows concept must therefore be developed with a frontal face with variable thicknesses and local stiffening (nerves).
- the new bellows shape originates novel arrangement concepts for the getter pellets, as well as the eccentricity of the tubes, which generate a free space in the covers that will be used for the new location of the getters, thus solving the problems found in the state of the art with the previous arrangements.
- the getter system of the invention is formed based on standard pellets without needing a specific manufacture for this development, which will be adhered to the lower part of the covers in the space left due to the eccentricity, thus avoiding the arrangement of a sheath and a protective mesh wherein the pellets are housed.
- the tube is also optimized by using the hole in the cover that is created due to the eccentricity existing between the inner metal tube and the outer glass tube.
- FIG. 1 State of the art Solel Solar System.
- FIG. 2 State of the art Solel Solar System LTD (IL 153872 A).
- FIG. 3 State of the art Schott (US2007034204 A1).
- FIG. 4 Eccentricity of the tubes of the invention.
- FIG. 5 Inner perspective of the end of the tube.
- FIG. 6 Outer perspective of the end of the tube.
- FIGS. 7-9 Alternate designs of the ends of the tube.
- FIGS. 1-3 show different designs of the state of the art (the references of said figures do not correspond to the originals; they have been unified for a better comprehension of this document).
- FIG. 1 represents a solution used by the company Solel Solar Systems Ltd that implies installing the non-evaporable getters ( 1 ) in the empty space between the glass tube ( 2 ) and the metal tube ( 3 ).
- FIG. 2 shows another solution of the same company, Solel Solar Systems Ltd, which in this case locates the getters ( 1 ) in a pellet-holding device, which is supported on two supports over the metal tube ( 3 ) and goes through part of the tube in the longitudinal direction.
- FIG. 3 shows the tube created by Schott, which locates the getters ( 1 ) in one of the two ends by putting the pellets in a ring-shaped holding mesh.
- the invention claimed herein is characterized, among other aspects, by the eccentricity existing between the metal tube ( 3 ) and the glass tube ( 2 ) as shown in FIGS. 4 to 6 .
- FIGS. 4 to 6 show the aforementioned eccentricity and, in the case of FIG. 4 , the area of the glass tube ( 2 ) being mirrored ( 7 ) for a greater capture of solar radiation.
- FIG. 5 shows a series of radial and equidistant nerves ( 5 ) with which the cover of the tube will be manufactured in order to increase its rigidity.
- the glass tube ( 2 ) has a greater diameter than current commercial tubes and is partially mirrored and located eccentrically with respect to the metal tube. In addition, it has a different dilatation coefficient than the former, which is normally manufactured in steel ( 3 ).
- the dilatation compensating element (bellows) ( 4 ) must allow, before the new thermal load defined above (description of the invention, point 3 ), the relative axial deformation between both tubes ( 2 , 3 ), while annulling the relative displacement between the metal tube ( 3 ) and the glass tube ( 2 ) at the same time.
- FIGS. 7-9 show three different solutions for the claimed invention.
- FIG. 7 two views are represented, an elevational view and an A-sectioned view in order to achieve a configuration wherein the cover ( 8 ) has a constant thickness but a series of radial nerves ( 5 ) have been added.
- the getter pellets ( 1 ) have been bonded, which, thanks to this advantageous way of positioning, admit all shapes and do not require any additional holding device.
- FIG. 8 The design of FIG. 8 is very similar, having a cover ( 8 ) with a constant thickness and radial nerves ( 5 ), although in this case, the nerves ( 5 ) slightly change their shape and are provided with a variable thickness, so they are thicker at one of the ends than the other. In the case of the preferred embodiment, the area closest to the center is thinner, thus optimizing the shape of the cover and minimizing the contribution of material. In terms of the getter pellets ( 1 ), as well as in the previous case, they can be of any shape because they are adhered to the cover at the holes between nerves ( 5 ), in the wider area due to the eccentricity of the tubes.
- FIG. 9 consists in providing the cover ( 8 ) with variable thickness ( 6 ) according to the areas that require greater rigidity and adhering the getter pellets ( 1 ) to the cover ( 8 ).
- the pellets ( 1 ) may be of any shape, although they have all been represented with an oval shape in FIG. 9 .
- cover ( 8 ) would have a variable thickness ( 6 ) and also nerves ( 5 ), and the pellets ( 1 ) would be bonded in the holes.
