Title:
HEAT EXCHANGE TUBE, HEAT COLLECTOR, SOLAR POWER GENERATION DEVICE AND SOLAR PHOTOTHERMAL POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/055193
Kind Code:
A1
Abstract:
A heat exchange tube, a heat collector, a solar power generation device and a solar photothermal power generation system. The heat exchange tube (100) comprises a heat release part (110), a heat absorption part (120) and a heat transfer conduit (130); the heat release part (110) is placed in liquid to be heated; the heat absorption part (120) is provided with a heat absorption surface (121), and the heat absorption surface (121) is arranged at a focus point of a focus lens (230); a first end of the heat transfer conduit (130) is in communication with the heat absorption part (120), and a second end of the heat transfer conduit (130) is in communication with the heat release part (110). By additionally providing the heat absorption surface (121) and placing the heat absorption surface (121) at the corresponding focus point, the heat absorption area can be increased, and the heat absorption effect is improved; moreover, the heat transfer conduit (130) and the heat release part (110) are provided, and the heat release part (110) is placed in the liquid to be heated, so that the temperature difference between the two ends of the heat exchange tube (100) is large, and the heat exchange effect can thus be effectively improved. In addition, the solar power generation device can integrate power generation and fresh water production, so that the photoelectric conversion rate is improved, the power generation cost is effectively reduced, and 24-hour continuous power supply can be achieved.
