Definitions
- the present invention describes a vacuum indicator system or evaporable getter of those used in solar receiver tubes.
- a vacuum indicator or evaporable getter consists of a tank of a volatile and reactive material that is introduced inside the vacuum zone so that, once the area is sealed, the material is heated and evaporated, deposited in the walls of the borosilicate tube and leaving a coating that will change color by oxidation if vacuum loss occurs.
- getter material is barium.
- more complex getters are often used, including aluminum, magnesium, calcium, sodium, strontium, cesium and phosphorus.
- the 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 vacuum is generated.
- the inner tube, through which the heating fluid circulates, is metallic and the outer tube is glass, usually borosilicate.
- a bellows-shaped expansion compensating device is placed, so that it allows the relative movement between the absorbent tube and the glass tube, absorbing the tensions that would be created by the difference between the expansion coefficients of both and guaranteeing So the void.
- this type of tube requires the installation of materials that detect and suppress hydrogen molecules that can be introduced into the vacuum zone. These molecules are produced by the thermal degeneration suffered by the oil that is used as a heat transfer fluid and circulates inside the metal tube, due to the high temperatures it reaches. These molecules end up passing through the metal tube and entering the vacuum zone, increasing losses and, consequently, significantly reducing the efficiency of the system.
- alloys of the non-evaporable getter type are always installed in the vacuum zone so that, in the case of any H 2 molecule, it is captured by the surface of this material.
- This document discloses a clip for retaining the elements that support the getter (or vacuum indicators).
- This clip has the area that supports the evaporable element and the area that supports the receiving tube. These areas have a certain elasticity and are made of sheet metal. Both areas have legs to hold the receiver tube and to support the getter. The legs of both zones are joined through two rigid bending edges.
- This geometry is adapted to the type of receiver tube that the SCHOTT applicant has, but it would not be valid for other designs in which there was for example borosilicate tube, concentric with absorber tube since it would interfere with it, in addition to requiring a completely handmade assembly.
- the US2004134484 patent also shows another support for getter but in this case formed by a channel (37) to which some legs (36) are attached that attach it to the absorber tube.
- the CN201209968 patent also shows an evaporable getter support that has a greater ease of attachment to the absorber tube but also requires several parts and welding for its manufacture and location.
- the present invention aims to provide a new geometry or a new design for the support of an evaporable getter so that it can be adapted to all types of receiver tubes in addition to achieving a more automated assembly.
- the invention consists of an evaporable getter support system that is designed as an alternative to what already exists in the market to be able to be installed in other types of solar energy receiving tubes and that has a much more automated assembly procedure than what exists until the moment.
- This system unlike the known state of the art, consists of a support composed of a single piece, of clip type and of more or less slender profile, whose upper part has a ring shape as it is where the evaporable getter tablet is housed .
- This tablet is supported by the legs of the stand itself, avoiding a piece of additional interface, as with most existing supports in the state of the art.
- This clip is fixed to the bellows expansion compensator, so that it is located within what will be the vacuum zone and so that it is accessible and manipulable from the outside, until the moment the end of the tube is closed to realize this vacuum.
- the support piece has a homogenized thickness that guarantees a sufficient and constant section to generate the electric field required for its heating as well as to withstand high temperatures.
- FIG. 5 Perspective of the support located on the compensator
- the support (1) in perspective. It can be seen that it is a support (1) in the form of a clip, made entirely of one piece, formed by two pins (2) that in its lower part, as seen in the Profile view of figure 4, they are folded forming a "S" (3) slightly deformed and joined at its top forming a ring (4), as seen in the elevation of figure 3, this ring being the place where the tablet (5) (figure 5) of evaporable getter will be located.
- Figure 5 shows how the support (1) is secured inside the receiver tube: the clip shape (3) of the lower part allows this support to be easily attached to the expansion compensating element (6), being secured in turn with a mooring element in the form of a bridge (7).
- the thickness will be 1 mm and will have the height that is desired and geometrically allowed, without affecting its functionality.
- the support is located at the base of the compensator, accessible and manipulable from outside to inside, and being manipulable throughout the process except for the successive activity of the execution of the vacuum process.
