Mode of execution
Embodiment one: referring to Fig. 1-Fig. 4, a kind of solar energy thermo-electric generation machine, comprises support, tracker, groove type paraboloid reflector, grammed switch formula temp difference engine, generator.The heater of described grammed switch formula temp difference engine is placed in the focal line of groove type paraboloid reflector, parallel with minute surface; The cooler of described grammed switch formula temp difference engine is placed in the outside further from minute surface than heater, parallel with heater.
Described heater and cooler, can be made up of multiple single tubes.
The cooler of described grammed switch formula temp difference engine can be installed fin to help heat radiation, and fin design is side to light area minimum and is coated with reflection material.
The heater of the switch type heat-exchange device combination of described grammed switch formula temp difference engine is circular-arc arrangement.
The heater of described grammed switch formula temp difference engine can be installed photovoltaic cell towards the one side of reflector, and other parts are coated with thermal-protective material.
The cooler of described grammed switch formula temp difference engine can be with pipe sealing to adopt liquid coolant or gaseous coolant to carry out cooling.
Described groove type paraboloid reflector can be one or two, a side that while only having one, grammed switch formula temp difference engine is arranged on to groove type paraboloid reflector, is arranged on grammed switch formula temp difference engine in the middle of two groove type paraboloid reflectors two time.
Described generator can adopt alternator, also can adopt DC generator.
Solar energy thermo-electric generation machine is an application of grammed switch formula temp difference engine, this scheme is assembled solar energy with groove type paraboloid reflector, for heating the heater (hereinafter to be referred as heater) of grammed switch formula temp difference engine, the cooler (hereinafter to be referred as cooler) of grammed switch formula temp difference engine carries out cooling with normal temperature air to it, make the larger temperature difference of generation between heater and cooler, grammed switch formula temp difference engine is converted into power by the temperature difference, then exports via generator electric power.
The cooling of cooler generally completed by air, but also can according to actual needs, cooler be enclosed in pipeline, then allow certain cryogenic liquide or gas flow piping, cooler is lowered the temperature, can improve the efficiency of temp difference engine with the method, but cost is also higher.
A solar energy thermo-electric generation machine can be installed one or two groove type paraboloid reflectors, and two groove type paraboloid reflector cost performances are higher.Below take two groove type paraboloid reflectors as example, the working procedure of this solar energy thermo-electric generation machine:
In the time thering is two groove type paraboloid reflectors, grammed switch formula temp difference engine is placed on the neutral position of two groove type paraboloid reflectors, the quantity of the switch type heat-exchange device combination of grammed switch formula temp difference engine need 2 doubly several, that is it can be 2 groups, 4 groups, 6 groups etc., half is evenly distributed in two groove type paraboloid reflectors on one side, takes turns to operate.In actual use, more that heat-exchange device number of combinations means that every group has the more time to realize heat exchange more fully, to improve whole efficiency.
The Article 2 path of improving the efficiency of heating surface is the surface area that increases heater and cooler, therefore heater and cooler can be designed to be made up of multiple thinner pipelines.
Heater, in the face of the side of reflector, can be installed photovoltaic cell, has so just carried out twice solar electrical energy generation: being once photovoltaic generation, is once photothermal power generation, and optical energy utilization efficiency is higher; Such combination only needs the seldom photovoltaic cell of amount, and cost is very low; Simultaneously in such combination, photovoltaic cell can play heat energy is evenly distributed to the effect on heater, and heater can be taken away the heat gathering on photovoltaic cell, reduces the temperature of photovoltaic cell, in the working life of improving photovoltaic cell, this is excellent cooperation.
This device uses generator that the power output of grammed switch formula temp difference engine is converted into electric power, and generator can be DC generator, can be also alternator.In using separately as distributed energy, device alternator is perhaps more practical, and various like this electrical equipment can directly access.In the time using as large-sized solar power station cluster, device DC generator can directly be used the various power transfer apparatus that are applied to photovoltaic, as inverter etc., does not need additionally to develop new equipment.
