System for supporting an evaporable getter, which can be installed in any type of solar power receiving tube and which is mounted using an automated method. The system consists of a clip-type supporting element having a substantially thin profile and an S-shaped base, the upper part thereof including a ring in which the pellet of evaporable getter is housed. The pellet is supported by the pins of the supporting element, dispensing with the need for an additional contact part in order to secure the pellet. The clip is secured to the bellows-type expansion compensator, such that it remains inside the vacuum zone of the solar power receiving tube.

System for supporting an evaporable getter or vacuum gauge

Insulating element for expansion compensation device and method for manufacture thereof, of the type used in solar energy collector absorber tubes, being formed by a single piece in the form of a ring and with a bellows-like end portion, which is filled with rock wool or other equivalent insulating material, so as to create a hot air chamber which minimizes heat losses.

Insulating element for expansion compensation device and method for the manufacture thereof

The invention relates to a method for producing a solar power receiving tube and to the resulting tube, which is of the type that includes: an outer glass tube, an inner metal absorber through which a heat-transfer fluid flows, and an intermediate area in which the vacuum is produced. The method comprises the following steps:

Method for producing a solar power receiving tube and resulting tube

New expansion compensating device and manufacturing method of the same, of those used in solar power absorber tubes featuring a dual bellows design where the height of the waves of the bellows is not regular, but the second wave is greater (where it supports more load) and diminishes towards the ends. With this design improving the performance of the receiver is achieved because it shortens the length of the device and consequently there is more surface area receiving solar radiation as well as it decreases the necessary diameter of glass tube and therefore its cost.
