Abstract
A double point focusing solar energy collection apparatus of the present invention includes a heat collector, a secondary concentrator, and a bracket. The heat collector includes a primary concentrator and a heat collection tube, in which the primary concentrator has a focus point. The secondary concentrator has a focus point. The bracket supports the primary concentrator, the heat collection tube, and the secondary concentrator. The heat collection tube is located between the primary concentrator and the secondary concentrator and located on the focus points of the secondary concentrator and the primary concentrator. By adding the secondary concentrator, which is a rotating paraboloid reflector or circular Fresnel reflector, it can achieve low light loss and high heat collection efficiency, and erosion of the heat collection tube by sand, rain, and snow can be effectively prevented, thereby extending the lifetime of the heat collection tube effectively.
