Specific embodiments
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment 1, as shown in Figure 1, the cool-storage type solar semiconductor refrigeration box mainly is made up of solar battery bracket 3, semiconductor chilling plate 7, semiconductor cold junction radiator 8, semiconductor hot junction radiator 6 and the cool storage material 11 of rotatable refrigerated cabinet 12, solar cell 1, adjustable-angle.
Solar battery bracket 3 is placed in refrigerated cabinet 12 tops, and solar cell 1 is placed on the support.Can adjust the inclination angle of solar cell by adjustment screw 2.The refrigerating box bottom is mounted with universal wheel 10, regulates the inclination angle and the refrigerating box direction of solar bracket, can make sunshine direct projection solar cell, thereby solar cell has maximum electric energy output.The electric energy of solar cell output inserts semiconductor chilling plate 7 and semiconductor chilling plate cool and heat ends fan 5,8, and semiconductor chilling plate work makes the refrigerating box internal temperature descend.Semiconductor cold junction radiator is placed in refrigerating box inside, installs near the semiconductor cold junction.Semiconductor hot junction radiator is placed in the refrigerating box outside, installs near the semiconductor hot junction.At enclosure space of refrigerating box bottom design, cool storage material (Decanol) 11 is placed in this space.The cold that semiconductor chilling plate is made is when making that the refrigerating box temperature descends, and cold is also absorbed by cool storage material and stores.At night or when overcast and rainy, semiconductor chilling plate loses power supply, can not freeze.At this moment, the cold that is stored in the cool storage material is released, thereby keeps the low-temperature condition of refrigerating box.
After solar cell is subjected to solar light irradiation, in solar cell, because photoelectric effect, produce DC voltage at lead-out wire two ends of solar cell.The DC current that solar cell provides is crossed semiconductor chilling plate, and portion produces paltie effect (Peltier effect) within it, causes semiconductor chilling plate one surface temperature to reduce, and becomes cold junction.Air contact in cold junction and the refrigerating box, and during air themperature, cooling piece absorbs heat from air and cool storage material in cold junction temperature is lower than refrigerating box, thereby makes temperature decline in the refrigerating box.Simultaneously, the part in the cold made of semiconductor chilling plate is absorbed by the cool storage material in the refrigerating box and stores.Semiconductor chilling plate another side temperature raises, and becomes the hot junction.The cooling piece hot junction contacts with the refrigerating box ambient air outside under the effect of hot-side heat dissipation device, because hot-side temperature is higher than ambient air temperature, so the hot junction emits heat to surrounding air.So the hot junction is flow through by electric current to the surrounding air liberated heat that Joule heat that semiconductor chilling plate produces and cold junction form from the systemic heat of refrigerating box.At night or overcast and rainy, solar cell can not output DC, so semiconductor chilling plate can not freeze.At this moment, the low-temperature condition of refrigerating box inside is kept by cool storage material.The heat that enters refrigerating box by the refrigerating box casing is absorbed by cool storage material, because what lay in refrigerating box is a kind of special cool storage material, this cool storage material has the absorption heat and the constant characteristics of temperature maintenance, therefore, the low-temperature condition in the refrigerating box can be kept the quite a long time.The quality that is placed in the cool storage material in the refrigerating box is big more, can Keep cool under powering-off state time of case low-temperature condition long more.
