Passive cooler with double cone with elliptic base

摘要

The passive re-cooler includes a sunshade (1) and radiator (3) forming the base of the sunshade. The base of the sunshade is elliptical and has a surface forming a constant angle with the recoolers axis. A infrared deflector is fitted on the base and a radiator (7) forms the base of it. The base of the deflector is also elliptical. The relationship between the large and small axes of the elliptical base is greater or equal to 1.1 or greater than 1.3. The sunshade has radiators on its exterior face. Incident rays near to the edge of the sunshade are directed to the base of the sunshade from the other side so as not to penetrate into the deflector. Infrared rays emitted by the sunshade and penetrating into the deflector leave the deflector after at least a reflection on the deflector wall. The angle between the re-cooler axis and the sunshade wall is greater than 23.5 degrees. The angle between the recooler axis and the wall of the deflector is about 10 degrees.
