Anti-freezing and anti-overheating variable-tilt heat collector

Abstract

The present invention provides an anti-freezing and overheating variable-tilt heat collector, which includes a shell assembly, a hot water assembly installed in the shell assembly, a shading assembly, and a phase-change accumulator filled in the shell assembly by an adjustable support foot assembly. Thermal material; the shell assembly includes a cover and a box, the cover and the box are hinged; the hot water assembly includes a vacuum heating tube installed in the box; the shading assembly includes a high-reflective film installed in the box, and the high-reflective film can be rolled receive or release. The anti-freezing and overheating variable-tilt heat collector of the present invention has high annual thermal efficiency and wide application range, and can be adjusted according to the solar altitude angle in different regions and seasons to improve the receiving efficiency of solar radiation; The variable heat storage material can ensure that the vacuum heating tube is not cracked by freezing. In summer, the opening and closing of the high-reflective film can be automatically controlled to prevent overheating of the heat collector and ensure the normal operation of the heat collector. The power consumed by the opening and closing of the high-reflective film is provided by photovoltaic panels and batteries.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and relates to a solar heat collector, in particular to an antifreezing and overheating variable-tilt heat collector. Background technique [0002] Energy issues have gradually become a bottleneck restricting the development of the international society and economy. It is imperative to develop solar energy resources, seek new impetus for economic development, and reduce fossil fuel consumption. At present, my country's energy structure consumes a lot of conventional energy, causing serious pollution, especially in the process of building design and use. The total energy consumption of buildings accounts for more than 1 / 3 of my country's total energy consumption. The development and utilization of solar energy in the process of building design and operation can adjust the structure of building energy consumption and realize clean heating. For the use of solar energy in buildings for heatin...
