    • A solar collector for a solar energy system comprises a solar absorber for converting solar radiation into heat, a heat transfer fluid for transferring heat from the solar absorber, at least one passage for flow of the fluid in contact with the solar absorber surface, and apparatus for creating a relative vacuum in the at least one passage so as to minimize the creation of a stagnant boundary layer of the fluid when it is pumped through the at least one passage. The at least one passage is preferably formed by a convoluted surface on the solar absorber which defines at least one groove, and a flexible sheet which overlies the convoluted surface and sealingly engages the surface through the action of a vacuum. The heat transfer fluid preferably is selected from the group of mineral oil, aliphatic hydrocarbon oils, and silicone oils.
    • 用于太阳能系统的太阳能收集器包括用于将太阳辐射转换成热的太阳能吸收器,用于从太阳能吸收器传递热量的传热流体,用于与太阳能吸收器表面接触的流体流动的至少一个通道,以及装置 用于在所述至少一个通道中产生相对真空,以便在泵送通过所述至少一个通道时最小化所述流体停滞边界层的产生。 所述至少一个通道优选地由太阳能吸收器上的回旋表面形成,其限定了至少一个凹槽,以及柔性薄片,其覆盖在回旋表面上并通过真空的作用密封地接合表面。 传热流体优选选自矿物油,脂族烃油和硅油。

    • Solar tracking apparatus for a solar energy system comprises at least one chamber containing a volatile fluid, a shading arrangement for controlling the degree to which the at least one chamber is exposed to the sun in dependence on the position of the sun so as to control the extent to which the fluid is vaporized due to solar heating of the at least one chamber, and apparatus for coupling the expansive force generated by vaporization of the fluid to a work piece to control the position, orientation, and/or operation thereof. Preferably, the solar tracking apparatus comprises a base pivotably mounted with respect to a pivot axis, first and second chambers mounted to the base in counterbalancing relationship with respct to the pivot axis, a conduit connecting the chambers for transfer to fluid therebetween, a volatile fluid disposed in the chambers for transfer therebetween, and a shading arrangement for controlling the degree to which each of the chambers is exposed to the sun such that a differential vapor pressure is created therebetween in dependence on the position of the sun which causes a predetermined transfer of the fluid between the chambers so as to change the proportion of the fluid disposed within each of the chambers and thereby cause the base to pivot into a predetermined orientation with respect to the position of the sun.
    • 用于太阳能系统的太阳能跟踪装置包括至少一个容纳挥发性流体的室,用于根据太阳的位置控制至少一个室暴露于太阳的程度的遮蔽装置,以便控制 由于至少一个室的太阳能加热,流体被蒸发的程度,以及用于将由流体蒸发产生的膨胀力耦合到工件以控制其位置,取向和/或操作的装置。 优选地,太阳能跟踪装置包括相对于枢转轴线可枢转地安装的基座,安装到基座的第一和第二腔室与抵抗枢转轴线的平衡关系,连接腔室以转移到其间的流体的导管,挥发性流体 设置在用于在其间转移的室中的遮光装置和用于控制每个室暴露于太阳的程度的遮光装置,使得根据太阳的位置而产生差异蒸气压,这导致预定的转印 腔室之间的流体,以便改变设置在每个室内的流体的比例,从而使得基座相对于太阳的位置枢转到预定的方位。
