摘要： A cavity receiver having an aperture through which concentrated solar radiation enters the cavity. Holes are provided in the bottom wall of the receiver through which cold air, which enters the cavity through the aperture, can be withdrawn by an aspirator. The outlet of the aspirator can exhaust the cold air to the atmosphere, or reintroduce the air into the cavity through holes adjacent to the aperture. Holes can also be provided in the top wall of the receiver, and an aspirator used to withdraw air from the cavity through the top wall holes and reintroduce it into the cavity through the bottom wall holes.
摘要翻译： 具有孔的空腔接收器，集中的太阳辐射通过所述孔进入空腔。 孔位于接收器的底壁中，通过该孔可以通过吸气器将冷空气通过孔进入空腔。 抽吸器的出口可以将冷空气排出到大气中，或者通过邻近孔径的孔将空气重新引入空腔。 孔也可以设置在接收器的顶壁中，并且抽吸器用于通过顶壁孔从空腔中抽出空气，并通过底壁孔将其重新引入空腔。
