Solar air heater capable of improving solar-thermal conversion efficiency and use method thereof

Abstract

The invention discloses a solar air heater capable of improving solar-thermal conversion efficiency and a use method thereof, and relates to the technical field of solar air heaters. The heater comprises an outer frame, the interior of the outer frame is fixedly connected with a heat exchange corrugated pipe, the bottom end and the top end of the heat exchange corrugated pipe communicate with an air inlet pipe and an air outlet pipe, one end of the air inlet pipe penetrates the outer frame and extends to the outer portion of the outer frame, and the end, located outside the outer frame, of theair inlet pipe communicates with a filter frame. According to the solar air heater capable of improving solar-thermal conversion efficiency and the use method thereof, forced heat exchange can be achieved, the air interaction speed is improved, the heat exchange area is effectively improved, within a certain length, the better heat exchange effect is obtained, the air passing speed can be effectively relieved, the air can have enough time in the heat exchange corrugated pipe to be subject to heat exchange, the interior of the device can be conveniently overhauled and maintained, it is ensuredthat the temperature in the device cannot be lost, the damage of the heat exchange corrugated pipe is avoided, and use cost is saved.

Description

Technical field [0001] The invention relates to the technical field of solar air heaters, in particular to a solar air heater for improving light-to-heat conversion efficiency and a method of use thereof. Background technique [0002] Solar energy refers to the radiant energy of sunlight, which is generally used to generate electricity in modern times. Since the formation of the earth, organisms have mainly survived by the heat and light provided by the sun. Since ancient times, humans have also understood that the sun can dry objects and use them as a method of preserving food, such as salt production and salted fish. However, with the reduction of fossil fuels, it is intended to further develop solar energy. There are two ways to use solar energy: passive utilization (photothermal conversion) and photoelectric conversion. Solar power is an emerging renewable energy source. In a broad sense, solar energy is the source of many energy on the earth, such as wind energy, chemical...
