During cause photovoltaic module work more than temperature 60 C, for some condenser systems, photovoltaic module temperature can be higher, and even more than 100
℃.Crystalline Silicon PV Module conversion efficiency and the negatively correlated relation of temperature, namely photovoltaic module operating temperature are higher, opto-electronic conversion
Efficiency is lower.Operating temperature often raises 1 DEG C, decrease in efficiency 0.4-0.5%.If in addition, photovoltaic module long-time high temperature work
Make, assembly life-span, acceleration component aging can be had a strong impact on.So photovoltaic generating system, particularly light gathering photovoltaic power generating system, are needed
Photovoltaic module is cooled down.According to whether the type of cooling, can be divided into active cooling and passive cooling by extra power.
Active cooling needs extra power to drive, such as air-cooled, recirculated water cooling, spray, and these radiating mode radiating effects are preferable, but into
This input is big, and the income of generation can not offset the increase of cost.Passive cooling does not need extra power, such as uses metal fin
Radiating, but the radiating effect is undesirable.
Current published patent（201210188749.4）, using the rising principle of plant, strong using water absorbing capacity
Fiber or fiber tube material are attached to the photovoltaic module back side, are absorbed water evaporative cooling by fibrous material.The patent passes through motor belt motor
Dynamic shaft coupling is rotated, then band driven fork moves to control absorbent material to enter tank or leave tank.Because each tank is needed
Want motor individually to control, be adapted to be controlled monolithic element in this way, and be unfavorable for carrying out concentration control to photovoltaic array
System.
The content of the invention
The utility model purpose is to provide a kind of water cooling for cooling to photovoltaic module by rainwater-collecting progress water evaporation
But heat sink.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of photovoltaic module water cooling cooling dress
Put, including photovoltaic module, water sucting plate, support, rainwater-collecting groove, sedimentation basin, water purifying tank, moisturizing water pump, control system, draining valve
And level sensor；The water sucting plate is bonded and fixed at the photovoltaic module back side, and water sucting plate lower end is immersed in water leg, rainwater collection
Collection groove is connected by drainpipe with sedimentation basin, is connected by water inlet pipe with water purifying tank.
Further, water sucting plate is clamped in the middle of water sucting plate reinforcing strip, two ends are bonded in the photovoltaic module back side, further reinforces and inhale
Water plate.
Further, control system controls water inlet and the switch of discharge outlet by photo resistance；When light intensity is less than
During certain value, drainage switch is opened, and the water in groove is drained into stillpot；When light intensity is more than certain value, drainage switch
Close, while moisturizing water pump is opened, give liquid level in rainwater-collecting groove moisturizing, groove to reach behind level sensor position, water pump stops
Work.
Further, moisturizing water pump is DC water pump, is powered using single photovoltaic module, passes through light-operated switch controlling pump
Open and close.
Further, the water sucting plate is by the one or more in water-absorbing resin, absorbent polymer fiber or string
Composition.
Further, water sucting plate reinforcing strip width is 5mm-20mm, and material is stainless bar or aluminium alloy or engineering plastics.
Further, the rainwater-collecting groove is semiclosed mouth structure, it is therefore intended that reduce trough inner water point evaporation, photovoltaic group
Part lower edge is convenient to carry out rainwater-collecting directly over rainwater-collecting channel opening.
Compared with prior art, the beneficial effects of the utility model are：
1st, using super absorbent material automatic ink-suction, without extra power, component is cooled by moisture evaporation, cooled
Effect is obvious.
2nd, using half seal type rainwater-collecting groove, the waste of water, saving water resource are reduced.
3rd, water sucting plate is controlled to be separated from water using emptying mode, adjacent tank is available by placed in series, can be to photovoltaic battle array
Row carry out centralized Control；Using automatic controlled water replanishing and draining, it is easy to unattended.
4th, tank is designed using sedimentation basin and water purifying tank, the water warp that the rainwater and evening rainwater-collecting groove being collected into are excluded
Precipitation tank for precipitation, water overflow after precipitation is to water purifying tank, and water pump is in water purifying tank, and because water have passed through precipitation, water quality is relative
Preferably, the fault rate of pump is reduced, the service life of pump is extended.
