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 end
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.

An expansion compensator adapted for use with solar energy receiving tubes comprising: two opposing symmetrically arranged bellows, each bellows having an asymmetric distribution of waves, each wave having a height, wherein: the second wave counting from an end of the expansion compensator closes
1. An expansion compensator adapted for use with solar energy receiving tubes comprising: two opposing symmetrically arranged bellows, each bellows having an asymmetric distribution of waves, each wave having a height, wherein: the second wave counting from an end of the expansion compensator closest to a lid of the receiving tube is the largest, andthe height of succeeding waves decreases in comparison to an immediately preceding wave as each end of the bellows is approached. 2. The expansion compensator of claim 1, wherein the waves of the bellows have a maximum height of 34 mm. 3. The expansion compensator of claim 1, wherein the expansion compensator has a length and the receiving tube has a total length, the length of the expansion compensator being less than 2% of the total length of the receiving tube. 4. The expansion compensator of claim 1, wherein the two opposing symmetrical arranged bellows are arranged concentrically. 5. The expansion compensator of claim 1, wherein the two opposing symmetrical bellows are attached to one another at only one point. 6. The expansion compensator of claim 1, wherein the symmetrical arrangement occurs between the waves of the different bellows in a cross-section of the expansion compensator. 7. A solar energy receiving tube comprising an outer tube and an inner tube, wherein the inner tube is connected to the outer tube with the expansion compensator of claim 1. 8. An expansion compensator for use with concentric tubing comprising: a double bellows comprising an inner and an outer bellows, the inner bellows having an inner wave section and the outer bellows having an outer wave section, the inner and outer bellows each having a first end and a second end and each wave section comprising a number of convolutions arranged as a series of waves, wherein, the inner and outer wave section each have an axial and a radial dimension, each convolution having a height in the radial dimension of the corresponding wave section;wherein the convolutions on each wave section have a distribution of heights, with the second convolution from the first end of each bellows having the greatest height of the wave section, and the other convolutions of each wave section having lesser height. 9. The expansion compensator of claim 8, wherein the height of successive convolutions of each wave section decreases as the first and second end of each bellows is approached from the second convolution. 10. The expansion compensator of claim 8, wherein the inner and outer bellows are connected at their second ends. 11. The expansion compensator of claim 8, wherein the waves on each wave section have an asymmetric distribution of heights. 12. The expansion compensator of claim 8, wherein the convolutions of the inner wave section correspond to the convolutions of the outer wave section along the axial dimension. 13. The expansion compensator of claim 12, wherein corresponding convolutions of the inner and outer wave sections are directed in opposite directions. 14. A solar energy receiving tube comprising an outer tube and an inner tube, wherein the inner tube is connected to the outer tube with the expansion compensator of claim 8. 15. The solar energy receiving tube, further comprising a lid attached to an end of the outer tube, wherein the first end of each wave section is closer to the lid than the respective second end.
