Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] as attached figure 1 As shown, a kind of compressed air wind energy heater based on the reverse Stirling cycle of the present invention includes a power unit, a transmission unit, an energy conversion unit and a heat storage unit; wherein the power unit includes a windmill blade 1 and a wind power transmission wheel 2, The transmission device is the transmission shaft 3, which is processed into a concave structure. The concave structure is divided into the left end straight section AB, the middle concave section CD and the right end straight section EF, and the length of the BC section is greater than the DE section. The straight section EF at the right end rotates at the center, the straight section AB at the left end and the concave section CD in the middle produce two rotating surfaces with different radii of rotation respectively; the heat storage ...

The invention relates to a pneumatic wind-driven heating device based on reverse sterling cycle. The heating device comprises a power plant, a transmission shaft, an energy conversion device and a heat storage water tank; the power plant comprises a windmill blade and a wind-driven transmission wheel, and after the transmission shaft is manufactured into rotation, a special-shaped structure of two rotary surfaces with different heights is generated; the energy conversion device is provided with a dual-cylinder piston-type reverse Sterling compressor of a left air cylinder and a right air cylinder, the left air cylinder is fixed at the exterior of the heat storage water tank and is higher than the heat storage water tank, and the lower part of the right air cylinder is immersed into the heat storage water tank; the windmill blade is connected with the wind-driven transmission wheel; the right end of the transmission shaft is connected with the wind-driven transmission wheel; one section of a higher rotary surface on the transmission shaft after rotation is articulated with a left piston through a left connecting rod; and one section of a lower rotary surface on the transmission shaft after rotation is articulated with a right piston through a right connecting rod. According to the invention, the wind-driven transmission wheel driven by wind converts wind energy into mechanical energy, the mechanical energy is converted into heat energy, and simultaneously heat is extracted from air, so that all-weather continuous and stable domestic hot water is obtained.
Description
technical field [0001] The invention relates to a wind energy heater, in particular to a wind energy heater which uses wind energy to compress air to do work to obtain heat energy, and belongs to the technical field of energy-saving equipment. Background technique [0002] At present, the technology of solar water heaters is quite mature and popular, but solar energy has low energy density and is greatly affected by factors such as weather, day and night, and seasons, making it difficult to obtain continuous and stable hot water. Wind energy, which is also a clean and renewable energy source, has attracted increasing attention, but the vast majority of existing wind energy heating devices convert wind energy into electrical energy through wind turbines, and then heat from electrical energy. In this type of technology, the two conversion processes of wind power and electric heat greatly reduce the overall utilization efficiency of wind energy, and at the same time greatly inc...
