Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of utilize light ratio that the linear Fresnel reflector rationally adjusts and reflex on the solar cell and with all the other sunshines reflex to the photo-thermal module, photoelectric transformation efficiency and the high photovoltaic and photothermal solar integrated apparatus of hot water heat energy.
The technical solution of the utility model is achieved in that a kind of photovoltaic and photothermal solar integrated apparatus, comprise the linear Fresnel reflector, receive sunlight receiver and the driving control unit of the reflection of linear Fresnel reflector, described receiver comprises solar battery module and is positioned at least one solar thermal collector module of leaking water of solar battery module periphery, the described solar battery module back side is provided with cooling water pipe and is connected to the heat carrier of cooling water pipe, the delivery port of described cooling water pipe links to each other with the water inlet of the solar thermal collector module of leaking water, described sunlight receiver is provided with temperature sensor, and described temperature sensor links to each other with the controller that the linear fresnel reflector of control rotates.
Further, solar radiation sensor is installed also on the described sunlight receiver, described solar radiation sensor links to each other with the controller that the linear fresnel reflector of control rotates.
Useful technique effect of the present utility model is as follows: described sunlight receiver is provided with temperature sensor, described temperature sensor links to each other with the controller that the linear fresnel reflector of control rotates, when temperature surpasses 25 degrees centigrade significantly, controller will be controlled linear fresnel reflector and rotate, thereby make the part sunshine reflex to the solar thermal collector module of leaking water of receiver, carry out the comprehensive utilization of photoelectricity and photo-thermal, when improving photoelectric transformation efficiency, can also produce the hot water with efficient heat energy; Because receiver has photoelectricity and two kinds of modules of photo-thermal, the zone is big simultaneously, and it is easier to focus on.

Fig. 2 is the side sectional view of photovoltaic and photothermal solar integrated apparatus in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, be described further by the utility model of embodiment.
As Fig. 1, shown in Figure 2, a kind of photovoltaic and photothermal solar integrated apparatus comprises linear Fresnel repeller field 1 and the high-order solar receiver 3 that is positioned at that is installed on the support 2.
Receiver comprise the concentrator solar cell module formed by one group of concentrator solar cell 45 and be positioned at directly over the receiver, under, the solar thermal collector module 6 of leaking water that comprises one group of closing-sunning type solar energy heat collector of front-left and front-right.The length of receiver is not less than the distance of repeller field on the receiver length direction, and the height of receiver concentrator solar cell module is not more than the height of a speculum in the repeller field.
Each piece concentrator solar cell back side all is pasted with a conducting strip 7, conducting strip links to each other with cooling water pipe 8, the water inlet 9 of cooling water pipe is positioned at the middle of cooling water pipe, the two ends of cooling water pipe are separately installed with a solar energy radio temperature sensor 10, the delivery port 11 of cooling water pipe links to each other with the water inlet of the solar thermal collector module of leaking water, the water inlet of each solar thermal collector module of leaking water is separately installed with a magnetic valve 12, and the delivery port 13 of each solar thermal collector module of leaking water is connected to attemperater respectively.The middle that the concentrator solar cell module receives the side of sunshine also is equipped with a solar radiation sensor 14.
The solar energy radio temperature sensor links to each other with the controller that the control linear Fresnel rotates respectively with solar radiation sensor, when the temperature value of solar energy radio temperature sensor significantly greater than 25 degrees centigrade and current solar radiation intensity during greater than setting value, controller will be controlled starting mode of pump, and open the magnetic valve of wherein one or more solar thermal collector modules of leaking water as required, make the water in the cooling water pipe force circulation at a high speed to take away the heat of concentrator solar cell module, give the cooling of concentrator solar cell module, when improving photoelectric transformation efficiency cold water has been carried out first heating, entered the solar thermal collector module of leaking water through the first water that heats and be heated into the hot water with efficient heat energy again.
If in the morning or at dusk because incident light is to tilt to be mapped on the linear fresnel solar reflector, so reflexing to sunshine on the receiver has part and is mapped on the solar thermal collector module of leaking water of front-left or front-right, therefore, controller will make the magnetic valve of the solar thermal collector module of leaking water of front-left or front-right open; If when sunshine is stronger, because the solar energy that reflexes on the concentrator solar cell module is too much, the concentrator solar cell temperature can be very high, photoelectric transformation efficiency descends, at this moment, directly over controller will make or under the magnetic valve of the solar thermal collector module of leaking water open, and the angle of change partial linear fresnel reflector, adjustment reflexes to the light ratio on the concentrator solar cell module, make too much sunshine reflex to the solar thermal collector module of leaking water, realize the comprehensive utilization of photoelectricity and photo-thermal.
