On deep fat output channel and cold oil output channel, connect one road pipeline in addition again, just can realize heat water supply functions very easily: as shown in Figure 1, on deep fat output channel and cold oil output channel, be respectively equipped with electromagnet cut off valve 39C and electromagnet cut off valve 39D, electromagnet cut off valve 39C is connected with oil water heat exchange device 51 by intelligent controller 40B, on oil water heat exchange device 51, be provided with temperature sensor 50B, be convenient to measure at any time temperature, oil water heat exchange device 51 1 ends are provided with cold water inlet 53 and hot water inlet 52.Utilize the heat of conduction oil just can provide hot water.
The operation principle of this solar cooker is that (focus temp is about 800-1000 ℃) injected on the spherical metal heat collector 16 after sunshine was seen through the focusing of Fresnel Lenses 3, spherical metal heat collector 16 inside are marked with high temperature heat conductive oil, oil after high temperature heat conductive oil will heat through No. 1 high temperature oil pump 33 is sent into vacuum canister seals 35, and heat energy is risen to application of temperature (the heat accumulation temperature is made as 400 ℃).Spherical metal heat collector 16 is to install with fixing form, for the heat energy that guarantees spherical metal heat collector 16 is not escaped by air scattering, a dual-layer vacuum glass ball cover 12 and isolate from outer air are housed outside spherical metal heat collector 16, thereby can reach the effect that the luminous energy individual event imports.Therefore between spherical metal heat collector 16 and vitreosil glass ball cover 12 one section space is arranged, there is gas in the space, has designed individual event air bleeding valve 15, avoids expanding in heating process and makes 12 explosions of vitreosil glass ball cover.Add the process of deep fat in injection, existed air pressure in the ball to stop for fear of the oil that flows into spherical metal heat collector 16 and can't discharge and stop up, therefore design the high-order blast pipe 34 of the centre of sphere, cold air sucks when preventing from not work.The height of high-order blast pipe 34 exceeds oiling face, prevents that oil is forced out in the exhaust process.Heated oil because the deep fat molecule lightens on top, is sent constantly into vacuum energy storage canister 35 via high temperature oil pump 33 with heat energy by 14 outputs of heating power efferent duct.Deep fat unidirectional stop valve 32 is to prevent from that temperature decline at night conduction oil from freely circulating to make heat-energy losses in pipe network.
In the process that Fei Nier lens 3 to spherical metal heat collector 16 focuses on, heat energy in the light wave is flowed by air and has taken away greatly, has therefore designed two-sided color steel rock wool filled board 6, can make light wave in the process that focuses on conduction, hear rate reduces greatly, and the utilization rate of photo-thermal significantly rises.In order to capture the energy of solar radiation all the time, so just must guarantee Fresnel Lenses centrally aligned sun center constantly, to obtain maximum solar energy, therefore designed and horizontally rotated (being made as 360 °) tracking section and automatic tracking section in the elevation angle (being made as 240 °) automatically.Rotate freely for the influence that prevents natural wind, therefore horizontal reducing motor 21 and elevation angle reducing motor 17 have been used in design.Tracking system and each several part electricity consumption are provided by solar photovoltaic cell panel 1 and accumulator jar 23.Accumulator jar 23 1 ends are connected with inverter 24 and H bridge motor driver 19, and the other end is connected with intelligent controller 40A.Inverter 24 can be exported 220V, the 50HZ power supply.
The stove part
The heat energy of vacuum energy storage canister 35 is sent into heat exchange type kitchen range 42 via No. 2 high temperature oil pumps 38 and is carried out heat exchange to heat sink 43, passes to heating metal range face then, and the serviceability temperature of opening intelligent controller 40A setting gets final product work.Cold oil electromagnet cut off valve 39A and the automatic conducting of deep fat electromagnet cut off valve 39B stop promptly to close voluntarily to prevent heat-energy losses.The each several part pipeline is all with soak material parcel, thermal insulation.No. 1 high temperature oil pump 33 is by No. 1 high temperature oil pump controller 25 controls, and No. 1 high temperature oil pump controller 25 is by inductor 9 and power-supply controller of electric 18 controls, operation when luminous intensity reaches setting work.
Wherein the tracking technique principle is as follows automatically for sunshine intelligence: horizontal light-sensitive cell sensory package 2 by about two light-sensitive cells and the shadow shields that are erected in the middle of two batteries form, shown in Fig. 4, elevation angle light-sensitive cell sensory package 5 is made up of two light-sensitive cell groups up and down and the shadow shields that are erected in the middle of two batteries, as shown in Figure 5, in the H bridge motor driver device 19 2 set control systems are arranged, one group of control elevation angle reducing motor 17, the horizontal reducing motor 21 of another group control, the difference that H bridge motor driver 19 drives 2 motors respectively turns to.
When four light-sensitive cells were subjected to same solar radiation, its voltage equated that H bridge motor driver 19 is in halted state; When light can not direct projection to four during piece photosensitive photovoltaic cell, divide following two kinds of situations: 1, because the effect of shadow shield, four photosensitive photovoltaic cells are subjected to different irradiations, the photosensitive photovoltaic cell voltage of the left side or top is greater than the right or following photosensitive photovoltaic cell voltage, H bridge motor driver 19 drives 2 motors respectively and rotates in the counterclockwise direction, after the motor rotation, Fresnel Lenses 3 is followed to move together and is made light parallel with shadow shield, i.e. light direct projection is to Fresnel Lenses 3.2, because the effect of shadow shield, four photosensitive photovoltaic cells are subjected to different irradiations, the photosensitive photovoltaic cell voltage of the right or bottom is greater than the photosensitive photovoltaic cell voltage of the left side or top, H bridge motor driver 19 drives 2 motors respectively and rotates along clockwise direction, after the motor rotation, Fresnel Lenses 3 is followed to move together and is made light parallel with shadow shield, i.e. light direct projection reaches new balance to Fresnel Lenses 3.
Vertical irradiation is to Fresnel Lenses 3 centers at any time so just can to guarantee light, and realization intelligence is from the motion tracking solar source.
