Detailed description of the invention
For making the purpose of the present invention, technical scheme and beneficial effect clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described in further detail.
As shown in Figure 1, the invention provides a kind of portable type solar energy refrigeration case, including solar panel 1, voltage stabilization and current stabilization device 2, casing 3, lock portable snap close 4 for casing 3, and be wrapped in the heat-insulation layer 5 outside casing 3, casing 3 external upper is provided with handle 15, it is simple to carry.Solar panel 1 generally adopts solar-powered collapsible cell panel 1, both can absorb solar energy to the full extent, is easy to carry again simultaneously.Producing electric current by the photoelectric effect of solar panel 1, power to after voltage stabilization and current stabilization device 2 whole equipment, heat-insulation layer 5 can farthest reduce and extraneous heat exchange, reduces energy loss.
Described casing 3 is internally provided with semiconductor refrigerating module 9, casing 3 is internal is additionally provided with the power module 6 that the electric energy that solar panel 1 produces is supplied to semiconductor refrigerating module 9, it is provided with temperature inductor 13 in described casing 3, casing 3 is internal is additionally provided with the controller 7 that casing 3 internal temperature detects and controls semiconductor refrigerating module 9 work in real time, controller 7 is generally single-chip microcomputer, temperature inductor 13 connects with controller 7 and power module 6 respectively, controller 7 connects with power module 6, voltage stabilization and current stabilization device 2 connects with controller 7, described casing 3 external upper is provided with liquid crystal display operation panel 8, liquid crystal display operation panel 8 connects with controller 7 and power module 6 respectively.
Described semiconductor refrigerating module 9 is by semiconductor refrigerating element 10 and is arranged on fin on semiconductor refrigerating element 10 11 and radiator fan 12 3 part being arranged on fin 11 forms, semiconductor refrigerating element 10 refrigeration end radiation fin 11 and fan 12, utilizing forced convertion to freeze, effect is better than free convection.After semiconductor refrigerating element 10 energising refrigeration, one end heat production, one end is produced cold, and dispel the heat through fin 11 and radiator fan 12 in hot junction, it is ensured that cold end refrigerating efficiency, and after the cold end refrigeration of semiconductor refrigerating element 10, cold is saved in casing 3.By arranging agent for storage of coldness 14 inside casing 3, it is possible to the cold long-time storage that refrigeration case is produced, with ensure illumination not enough and unglazed according to time, low temperature can be maintained for a long time in casing 3.
The operation principle of the present invention is: convert solar energy into electric energy by the photoelectric effect of solar panel 1, the electric energy produced is supplied to semiconductor refrigerating module 9 and controller 7 after power module 6 is changed, by temperature inductor 13 and controller 7, casing 3 internal temperature is detected in real time, controller 7 controls semiconductor refrigerating module 9 to realizing refrigeration in casing 3, make casing 3 internal temperature reach setting value, and temperature can accurately control to 0.1 degree.In this process, casing 3 external upper is provided with liquid crystal display operation panel 8 and shows the duty of casing 3 internal temperature and critical piece, and receive the parameters such as desired temperature.The temperature of box house is set by user according to demand, and controller 7 receives setting value, according to setting value, controls semiconductor refrigerating module 9 and works.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements both fall within the scope of claimed invention.Claimed scope is defined by appending claims and equivalent.
