Description

Technical Field

[0001] The present invention relates to the field of renewable energy utilization, and in particular to a device for efficiently converting renewable deep space energy into cooling, heating and power supply. Background Art

[0002] Renewable deep space energy includes solar energy and radiation energy. As a renewable energy source, solar energy has been widely used at home and abroad. It can be used for power generation, heating and cooling. It accounts for an increasing proportion of the world's energy and is one of the main directions of future energy development. Radiative cooling is a zero-energy, passive cooling technology that uses the spectral characteristics of the earth's atmosphere in the 8-13μm band to transfer heat directly to space through thermal radiation. The radiative cooling process is carried out throughout the day and does not consume electrical or mechanical energy. It has good application prospects.

[0003] The biggest bottleneck problem of solar energy and radiant cooling is that the energy density per unit area is too low, and solar energy can only be used during the day, which requires a large amount of land resources and space, greatly limiting the application effect of solar energy and radiant cooling.

[0004] Improving the utilization rate of renewable energy per unit area is a hot topic of research at home and abroad. The current technical status is that only a single energy utilization method can be realized in the same area, and only one of solar energy utilization and radiation cooling can be chosen. The main way to increase energy density is still to focus on improving the efficiency of solar energy and radiation cooling itself. Summary of the invention

The whole process does not generate energy exchange with the outside world.

[0012] The light-transmitting radiation cooling material transfers heat to the deep space in the form of 8-13μm radiation light waves. The cold energy generated by itself is transferred to the cooled medium in the cooled medium channel through heat conduction of the light reflecting plate, thus realizing radiation cooling.

[0017] As an improvement of the present invention, the renewable deep space energy efficient conversion cooling, heating and power supply device can be used individually or in combination of multiple devices, and the placement positions do not interfere with each other.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Example

[0027] like Figure 1 As shown, this embodiment provides a renewable deep space energy efficient conversion cooling, heating and power supply device, which mainly includes a solar energy conversion device 1, a radiation cooling device 2, a rotating bracket 3, a No. 1 lifting rod 4, a No. 2 lifting rod 5 and a support base 6.

[0028] The solar energy conversion device 1 and the radiation cooling device 2 are fixedly connected to the rotating bracket 3 at a vertical angle. Figure 3 In the combination shown, specifically, the solar energy conversion device 1 is placed in parallel and does not block each other, and the radiation cooling device 2 is also placed in parallel and does not block each other. The vertical structure formed by the solar energy conversion device 1 and the radiation cooling device 2 can rotate freely around the rotating bracket 3. The first lifting rod 4 and the second lifting rod 5 are fixed on the support base 6 at intervals, and the two ends of the rotating bracket 3 are respectively connected to the lifting ends of the first lifting rod 4 and the second lifting rod 5.

[0029] The rotating bracket 3, the No. 1 lifting rod 4, and the No. 2 lifting rod 5 are respectively equipped with power devices. The No. 1 lifting rod 4 and the No. 2 lifting rod 5 work together to adjust the inclination angle of the rotating bracket 3 relative to the ground plane. The rotating bracket 3 can drive the solar energy conversion device 1 and the radiation refrigeration device 2 to rotate around it. Through the coordinated movement of the three, it can be ensured that the sun-facing side of the solar energy conversion device 1 is always perpendicular to the sun's rays, and the solar energy is utilized to the greatest extent. At the same time, because the radiation refrigeration device 2 is arranged vertically to the solar energy conversion device 1, the reflection surface of the radiation refrigeration device 2 is always parallel to the sun's rays. The radiation refrigeration device 2 does not need to directly reflect sunlight, which can minimize the impact of direct sunlight on radiation refrigeration.

[0030] Specifically, the motion control of the rotating bracket 3, the first lifting rod 4, and the second lifting rod 5 can be controlled by the program intelligently according to the longitude and latitude of the device. During the day, the sun-facing surface of the solar energy conversion device 1 rotates from east to west following the sun's rays. During the whole process, the sun-facing surface of the solar energy conversion device 1 is always perpendicular to the sun's rays, and the reflective surface of the radiation cooling device 2 is always parallel to the sun's rays. During the night, the sun-facing surface of the solar energy conversion device 1 is reset to face due east.

[0031] The solar energy conversion device 1 can adopt one or more of solar photovoltaic panels, solar thermal collectors, and solar adsorption refrigeration devices to convert the received solar energy into electrical energy, thermal energy or cold energy. The specific structures are all existing and will not be repeated here.

[0032] The structure of the radiation cooling device 2 is as follows: Figure 2 As shown, it includes vacuum glass 21, light-transmitting radiation cooling material 22, light reflecting plate 23 and cooled medium channel 24. Light reflecting plate 23, radiation cooling material 22 and vacuum glass 21 are stacked from inside to outside, and cooled medium channel 24 is formed between two layers of light reflecting plates 23. Vacuum glass 21 is used for light transmission and heat preservation. Of course, it can also be replaced with other light-transmitting and heat-insulating structures, such as light-transmitting heat-insulating covers, etc., to isolate the heat exchange inside and outside the radiation cooling device. Light-transmitting radiation cooling material 22 is used for light transmission and full-time radiation cooling. Its working characteristics are similar to black body radiation. Its thermal radiation is mainly emitted in the form of infrared rays with a wavelength of 8-13 microns. Infrared rays in this band are difficult to be absorbed by the atmosphere and can reach outer space directly, thereby taking away the heat of the radiation cooling device. Light reflecting plate 23 is used to reflect light, so that the radiation cooling device cannot obtain heat from the sun, providing a prerequisite for radiation cooling. Cooled medium channel 24 is used to transport the cooled medium, and timely and effectively distribute, transfer and utilize the cold.

[0033] Specifically, the working process of the radiation cooling device 2 is as follows:

[0034] The uncontrollable diffuse reflected light in the atmosphere passes through the vacuum glass 21 and the light-transmitting radiation cooling material 22 in sequence, is reflected by the light reflecting plate 23, passes through the light-transmitting radiation cooling material 22 and the light-transmitting vacuum glass 21 in sequence, and returns to the atmosphere. The whole process does not generate energy exchange with the outside world.

[0035] At the same time, the light-transmitting radiation cooling material 22 is isolated from the outside atmosphere by heat conduction and convection heat exchange through the vacuum glass 21. The working characteristics of the radiation cooling material are similar to those of blackbody radiation. The wavelength of its thermal radiation is controlled at 8 to 13 μm. The radiation light waves of 8 to 13 μm can effectively penetrate the atmosphere, exchange heat with the deep space at all times, and transfer heat to the deep space in the form of radiation light waves. The cold energy generated by itself is transferred to the cooled medium through heat conduction through the light reflecting plate 23. The cooled medium distributes, transfers and utilizes the cold energy in a timely and effective manner through the diverse structures of the cooled medium channel 24, thereby realizing radiation cooling.

[0036] In addition, multiple devices for efficiently converting renewable deep space energy into cooling, heating and power supply can be used in combination and placed in positions that do not interfere with each other, so as to increase the light-receiving area of ​​the solar energy conversion device 1 and the heat radiation area of ​​the radiation refrigeration device 2, thereby improving energy utilization.

[0037] In summary, the renewable deep space energy efficient conversion cooling, heating and power supply device of the present invention, the solar energy conversion device 1 converts light energy into the required electrical energy and thermal energy to realize the power supply and heating of the device, and the radiation refrigeration device 2 transmits its own thermal energy to the deep space of the universe in the form of radiation light waves to realize the cooling of the device. The entire device realizes the high-efficiency conversion and simultaneous superposition of two deep space energies, solar energy and radiation energy, in the same area, greatly improving the energy utilization rate and energy density per unit area, saving a lot of land resources and space. At the same time, the special vertical design of the solar energy conversion device 1 and the radiation refrigeration device 2 makes them not affect each other when working, further improving the effect of simultaneous superposition.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable ordinary technicians in the field to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made based on the essence of the content of the present invention should be included in the protection scope of the present invention.
