Embodiment Construction

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0036] Such as figure 1 As shown, the surface modification is carried out on the surface of the concave mirror, the concave mirror is made hydrophobic as a whole, and the local part is made hydrophilic in the form of dots, with an appropriate distance between the dots. When the temperature drops at night and the air humidity increases, the small water droplets formed will condense on the hydrophilic point-shaped surface. As the water droplets grow, the outside of the water droplets will gradually touch the hydrophobic surface. When the gravity of the water drop is so great that the water drop can slide down, the water drop will slide along the surface of the concave mirror to the bottom of the concave mirror. During this process, the water droplets will clean the surface of the...

Abstract

The invention discloses a self-cleaning solar thermo-acoustic refrigeration device for desert areas. The self-cleaning solar thermo-acoustic refrigeration device comprises a second glass tube, wherein the top of the second glass tube is connected to a resonant tube, a second thermo-acoustic stack is arranged in the top of the second glass tube, and a first thermo-acoustic stack is arranged on the top of the resonant tube and is arranged in a first glass tube with the top sealed; a solar condensation device is fixed outside the second glass tube so that the lower part of the second thermo-acoustic stack can be located on the focal point of the solar condensation device, and a hot water exchange tube is arranged outside the top of the second glass tube. The self-cleaning solar thermo-acoustic refrigeration device has the beneficial effects that a concave mirror serves as a solar concentration device and can collect circulation refrigeration water, the water can be used for plant drip irrigation and daily life, and therefore the water resource can be saved; the whole device is divided into a plurality of sections by the two thermo-acoustic stacks, the thermo-acoustic stacks make contact with the exterior, fluid can directly flow through the interiors of the thermo-acoustic stacks and reinforce heat exchange, and therefore the cold side can realize better thermo-acoustic effect, the utilization rate of the cold energy can be increased, and the energy can be saved.

Description

technical field [0001] The invention relates to the field of refrigeration in desert areas, in particular to a self-cleaning solar thermoacoustic refrigeration device in desert areas. Background technique [0002] In the process of my country's national economic development, energy and environmental issues play a decisive role. my country's fossil fuel resources are very limited, and the development and utilization of fossil fuels will bring serious environmental pollution problems. Therefore, the development and utilization of new energy and renewable energy has become a strategic decision for my country to solve energy and environmental problems. The utilization of solar energy in renewable energy does not need to consider its energy economy, but my country has abundant solar energy resources, and the total annual radiation is 930-2330kWh / m 2 a, the annual sunshine hours are >2000h, and the total radiation is higher than 1630kwh / m 2 The area of ​​a accounts for more t...
