Background

At present, the thermal efficiency of a small solar cooker is poor due to the restriction of a manual or mechanical tracking mode, the thermal efficiency of the solar cooker is greatly improved along with the application of a full-automatic solar tracking device, but under the influence of a structure, the focus of a solar concentrator (solar cooker) is generally arranged obliquely above the solar concentrator (solar cooker) (namely between the solar cooker and the sun), so that inconvenience is brought to the installation and the use of a heat collector of the solar cooker, such as a pot, a water tank and the like, even if the focus of the concentrator (or the solar cooker) is arranged obliquely below the solar concentrator, but under the influence of a wind-guiding structure, no matter wind comes from the concentrator to the light or the backlight direction, no diversion channel exists because of the wind, the wind load of the concentrator is large, the drifting of the device tracking can be caused, the tracking failure can be caused when the device is serious, the focusing failure can be caused, and the light-heat conversion efficiency of the concentrating solar energy utilization device is, in addition, the heat collector (such as a solar cooker) is arranged below the condenser, so the space size of the condenser and the heat collector (such as a solar cooker) in the direction of incident light of the sun is long, the rotary space of the condenser on the automatic solar tracking device is large, therefore, if the condenser with the wind channel, the focusing position (namely the installation position of the heat collector) below or inside the condenser and the transmission and reflection of the condenser are directly condensed to the same position (namely the focus) is invented, the condenser has the advantages that the focus of the solar condenser (such as a solar cooker) is arranged below the condenser (such as a solar cooker), the disadvantage that the light path is changed and the light is condensed again for two times or more times is overcome, and the blowing force of wind to the condenser can be weakened, so the wind load resistance of the condenser can be improved, the tracking deviation is reduced, and the overall energy efficiency of the tracking type solar condenser (solar cooker) photo-thermal conversion device is improved, meanwhile, the space size occupied by the rotation of the condenser and the heat collector (such as a solar cooker) under the automatic tracking condition is reduced because the focusing position (namely the mounting position of the heat collector) is in the condenser, the space occupation of the whole solar photo-thermal conversion device is reduced, and the enlargement of the solar photo-thermal conversion device is facilitated.
