Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cooling system for a roof solar cell module,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device for cooling a solar cell module mounted on a roof of a house, a factory, a barn or a general building, and more particularly to a cooling device for cooling a solar cell module installed on a roof, And more particularly, to a cooling apparatus for a roof solar cell module capable of uniformly spraying cooling water to a space below or spaced apart from a plurality of solar cell modules installed therein to cool the entire solar cell module heated by the sunlight continuously irradiated .

Generally, a solar cell module that generates electricity using solar light is installed on a roof of a house, a factory, a house or a general building with a lot of sunlight.

However, although the solar cell module is a device that generates electricity by receiving solar energy, the power generation efficiency is lowered when the solar cell is heated by solar energy. That is, in a generally known silicon solar cell module, the power generation efficiency is reduced by 0.4 to 0.5% due to a temperature rise of 1 ° C. When the solar cell module is installed on the roof, the temperature of the solar cell module is increased to 70 ° C. . Therefore, if the solar cell module exhibiting the power generation capacity of 10 kW at 25 ° C is at 70 ° C, the power generation capacity is reduced to about 8 kW.

Therefore, in spite of a large amount of solar radiation in the summer, the surface temperature of the solar cell module is kept at 60 ° C or higher, and the amount of generated electricity is reduced. To suppress the decrease in power generation efficiency due to such temperature rise, Cooling technology has been proposed.

The following is a typical prior art related to the cooling device of a solar cell module.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.

First, a cooling apparatus for a roof solar cell module according to the present invention is installed on a roof 100 of a building including a housing as shown in FIGS. 1A and 2B. In addition, the solar cell module installed in the roof 100 may be a general power generating device that generates power using solar light, and more preferably, the main components of the solar cell module, The exterior including the bottom of the module is waterproofed.

1, the solar cell module is spaced apart from the upper part of the roof 100 by a support having a predetermined height, the lower part of which is fastened to the upper part of the roof 100 and the upper part thereof is fastened to the solar cell module, . At this time, the height of the spacing space may be varied according to the environment in which the solar cell module is installed.

In addition, since the solar cell module is generally manufactured in a predetermined unit standard, a plurality of solar cell modules can be installed on the roof 100 according to the area of the roof 100, and the roof 100 ) May be constructed horizontally with respect to the side wall of the building or may be formed with an inclined structure.

Specifically, the cooling apparatus of the roof solar cell module according to the present invention includes a cooling water tank 10 for temporarily storing cooling water; And a sprayer 20 connected to the cooling water tank 10 through a cooling water supply pipe 11 and installed on the roof 100 to spray the supplied cooling water.

That is, the cooling water tank 10 is configured to store the cooling water supplied to the injector 20, and temporarily receives the cooling water from an external supply source such as water, stores the cooling water in the cooling water supply pipe 11 To the sprayer (20).

At this time, the cooling water may be natural water supplied through the water, or may be cooling water including a coolant having excellent heat exchange performance. The cooling water tank 10 is configured to supply the cooling water stably to the injector 20. Therefore, when the cooling water supply facility capable of stably supplying the cooling water can be provided without the cooling water tank 10, . ≪ / RTI >

In addition, the injector 20 is configured to inject cooling water into a spacing space formed in a lower portion of a plurality of solar cell modules spaced apart from the upper portion of the roof 100. The centrifugal blower fan And the cooling water supplied from the cooling water tank 10 is injected through the injection nozzle 30 and the injection nozzle 40.

At this time, the sprayer 20 is constructed so that the lower end of the sprayer 20 is closed, and a suction unit 22 is formed in front of a blower room 21 in which three surfaces of the upper and left and right main walls are opened. And a centrifugal blowing fan 30 for blowing the wind sucked by the suction unit 22 to the outer periphery of the air blowing chamber 21 is mounted on the blowing fan 21.

The injector 20 is also provided with a warm induction vane 23 and a half induction vane 24 at predetermined intervals in the air blowing chamber 21 equipped with the centrifugal blowing fan 30, An air blowing device for sending out the wind in the spray direction of the spray nozzle 40; A spray nozzle 40 is provided on the outer periphery of the air blowing chamber 21 of the injector 20 so as to be able to switch its position from the injection nozzle device pipe toward the opening portion of the air blowing chamber 21 or outside the opening portion, (Not shown) having a cooling water injector (not shown); A pump (not shown) for sucking the cooling water of the cooling water tank 10 through the cooling water supply pipe 11 and supplying the cooling water to the injection nozzle device pipe through a delivery pipe (not shown); And a centrifugal blower fan driving device for transmitting power to the rotary shaft of the centrifugal blower fan 30. [

At this time, the centrifugal blower fan 30 can be replaced with any one of silicon fan, radial fan, and deep fan (sirocco fan).

In addition, the centrifugal blower fan driving apparatus may be configured in various ways. However, in a preferred embodiment, the rotary shaft of the driving means such as the driving motor is connected to the rotary shaft of the sirocco fan, the rotary force of the sirocco fan is converted into the rotary force of the sirocco fan, Respectively.

On the other hand, Fig. 7 shows the flow of air in the air blowing chamber 21.

As shown in FIGS. 7 and 8, the inflow air introduced in the direction of the rotation axis by the rotation of the sirocco fan located in the center of the air blowing room 21 spreads in the radial direction and exits the air blowing room 21.

At this time, an induction vane (a full induction vane, a half induction vane) is installed in the air ventilation chamber 21 to guide the size and direction of the airflow at a predetermined interval in the circumferential direction. When the sirocco fan rotates in the counterclockwise direction when viewed from the front, the left half (AB) is provided with the full guidance guide vane (23) having a full width around the central portion (A) in the vertical direction, (AC) is provided with a half guide vane (24) which covers only the center of the width. If the sirocco fan rotates in a clockwise direction when viewed from the front of the air blowing chamber 21, a warm air guide vane 23 having a width of one half on the right side of the center A is installed , And the left half (AB) is provided with a half guide vane (24) which is half of the width.

In FIG. 7 of the present invention, when the rotary vane of the sirocco fan passes vertically downward, the air is continuously compressed and the compressed air is simultaneously discharged when the sirocco fan first moves upward from the downward direction. Accordingly, when the sirocco fan rotates in the counterclockwise direction, the amount of the air exiting to the right half (AC) becomes larger than the amount of air exiting to the left half (AB) The amount of outgoing air does not become symmetrical with respect to the left and right sides. However, by applying the warming guide vane 23 and the half guide vane 24 proposed in the present invention, • Uneven blowing amount in the right direction can be uniformly adjusted.

In addition, in order to more precisely adjust the amount of wind blowing, the long holes 26 are drilled on both side ends and one end side so as to adjust the radial depth of the warming guide vanes 23 and the half guide vanes 24, And a fastener (25) for fastening the guide wing (23) and the half guide wing (24). Therefore, if the warm guide vane 23 and the half guide vane 24 are moved and fixed in the center direction, the air blowing amount is increased, and if they are fixed far from the center direction, the air blowing amount can be adjusted to be smaller.

Therefore, the blowing air introduced into the air blowing chamber 21 can be uniformly adjusted by the provision and adjustment of the warm guide vane 23 and the half guide vane 24.

On the other hand, in the air blowing chamber 21, cooling water is transferred by a pump (not shown) through a cooling water supply pipe 11 connected to a cooling water tank 10 in which cooling water is stored. The injection nozzle 40 is coupled to an end of the cooling water supply pipe 11 such that the injection nozzle 40 can be disassembled and assembled by a bolt fastening method and the injection nozzle 40 can be constituted of one or a pair according to the injection quantity of the cooling water .

It is preferable that the injection nozzle 40 is located at the outer end of the air blowing chamber 21 to prevent the cooling water injected from the injection nozzle 40 from adhering to the inner wall surface of the air blowing chamber 21.

9 shows a rear perspective view of the air induction duct 50 when it is coupled to the injector 20. As shown in Fig.

The cooling water sprayed to the upper part of the air blowing room 21 through the air blowing room 21 of the injector 20 can be sprayed to the separated space located farthest from the sprayer 20 as shown in FIGS. The blowing induction type duct 50 is fastened to the upper side of the air blowing chamber 21 by a fastener 25 so as to be separated and joined.

In order to spray the cooling water farther to the left and right sides of the injector 20, the blow induction type duct 50 is moved from the injector 20 to the left and right sides and then fixed with the fastener 25 So that a plurality of fixing holes 27 can be drilled in the lower end of the air induction duct 50 and the injector 20 at intervals. Accordingly, the cooling water can be injected not only on the upper side but also on the left and right sides of the air blowing chamber 21.

The air induction duct 50 may be manufactured in various ways according to a specific application. In one preferred embodiment, the air induction duct 50 is coupled to the upper portion of the injector 20 and has a long trapezoidal duct extending vertically upward .

At this time, two elongated sidewise extension plates 51 provided parallel to each other so as to maintain the same interval as the width of the air blowing chamber 21 of the injector 20 are fixed to the upper end of the injector 20, And an upper end of the upper end plate is coupled with a fixing rod 54 for holding and fixing the gap between the two extension plates 51. [

On the other hand, in the interior of the air induction duct 50, an airflow guiding vane 52 is formed so as to be inclined from both sides to the upper side so as to be fixed by the fastening means 25 so that air blown from the air blow chamber 21 is directed toward the upper side .

The ventilation guiding vanes 52 are formed by inserting the ventilation guiding vanes 52 along the fastening holes 25 for fixing the ventilation guiding vanes 52, The depth of the slot 26 can be adjusted. By adjusting the depth as described above, it is possible to uniformly adjust the injection of the cooling water dispensed unevenly in the left and right directions. The injection amount of the cooling water injected in accordance with the distance from the injector 20 to the spaced- The spraying force can be controlled.

The cooling water supply pipe 11 is vertically installed along the outer surface of the air induction duct 50 so that the cooling water can be discharged into the air induction duct 50, The induction pipe 57 is protruded to the inside of the induction duct 50 and the spray nozzle 40 is mounted.

In this case, the cooling water supply pipe 11, the induction pipe 57 and the injection nozzle 40 are all fastened in a bolt connection manner so that when the blow induction type duct 50 is not used, the injection nozzle 40, The duct 57, the cooling water supply pipe 11, and the air induction duct 50 in this order.

11 shows an air induction duct 50 according to another embodiment of the present invention.

A pair of extension plates 51 having a rectangular shape and extending in the direction of the vertical direction are provided at the upper portion of the injector 20 so as to be spaced apart by a distance of the air blowing room 21 in order to raise the blowing air to the upper side of the injector 20 And an air induction duct 50, which is bolted parallel and parallel to each other so that the front and rear surfaces of the extension plate 51 form a long flow path from the lower side to the upper side.

At this time, a side plate 56 having a certain height at the lower side of the side surface is coupled to the side surface of the air induction duct 50 to block a part of the side surface. If the length of the side plate 56 is too short, there is a possibility that the side surface of the ventilation induction duct 50 is opened too much and the jetting distance of the jetted cooling water may not be secured sufficiently. The cooling water may not be sufficiently transferred to the space. Therefore, the length of the side plate 56 is preferably 2/3 or more from the bottom.

Meanwhile, the center of the inside of the air induction duct 50 includes a partition plate 55 that divides the inner flow path of the air induction duct 50 in the vertical direction into left and right, Is provided with an electric induction vane (23) on the vertical lower portion of the partition plate (55).

According to the above configuration, the distribution amount of the cooling water fed to the left and right sides of the blow induction duct 50 can be precisely adjusted according to the fixing depth of the warm induction vanes 23 in accordance with the rotation direction of the sirocco fan The effect can be obtained.

An air blowing guiding vane 52 is formed in the interior of the air induction duct 50 so as to be inclined from both sides to the upper side as necessary and is fixed by a fastening member 25, As shown in Fig.

The roof 100 on which the injector 20 is installed is provided with a cooling water receiver 60 in the longitudinal direction of the roof 100 at the lower end as shown in FIG. 100 to the lower end of the roof 100 and then recovered by the cooling water receiver 60 and reintroduced into the cooling water tank 10.

That is, the cooling water injected from the injector 20 flows along the space formed between the lower part of the solar cell module and the upper part of the roof 100, and then the cooling water is formed on the upper part of the roof 100 by its own weight, It flows down along the upper surface. At this time, it is obvious that the flow direction of the cooling water is directed toward the lower side of the roof 100, and the term "lower side of the roof 100" refers to the lowermost portion of the roof 100.

The used cooling water flowing into the cooling water receiver 60 is transferred to a water storage tank (not shown) through a water discharge pipe (or water discharge channel) connected to the cooling water receiver 60 and is treated as wastewater, And can be recycled.

At this time, the used cooling water transferred to the water discharge storage tank or the cooling water tank 10 may be transferred to the water discharge storage tank or the cooling water tank 10 after purified water treatment.

That is, when the cooling water receiver 60 is provided at the lower end of the roof 100 to recover the used cooling water, the cooling water injected into the spacing space flows down along the upper part of the roof 100, 100), it is possible to solve the problem of wetting the surrounding soil and to reduce the amount of wastewater.

In addition, the injector 20 may be installed at any position of a long rectangular shaped roof 100 (hereinafter referred to as a "rectangular roof 100") which is generally long in the horizontal direction, The cooling water injected from each of the injectors 20 is directed toward the center of the lower portion of the roof 100 and is sprayed downward in the diagonal direction .

That is, since the cooling water injected from the air induction duct 50 of the injector 20 can be injected farther than the cooling water injected from both sides of the injector 20, the pair of the injectors 20 can be injected into the rectangular roof 100 The cooling water is injected into the diagonally spaced spaces formed in a long direction toward the center of the lower portion of the roof 100 formed longer than the width of the roof 100 .

At this time, it will be apparent that the direction of the ventilation induction duct 50 faces the longest diagonal line of the virtually divided roof 100.

2B, the injectors 20 are provided at both lower vertexes of the long rectangular roof 100 having a long axis in the horizontal direction, and are connected to the blow-induction ducts 50 of the respective injectors 20 May be configured to be diagonally upwardly directed toward the center of the upper portion of the roof 100.

That is, the cooling water injected from the injector 20 installed on the roof 100 is sprayed to the upper diagonal portion of the roof 100 by the spraying force of the injector 20, and the upper portion of the diagonal line of the roof 100 is fogged The moved cooling water condenses with water droplets on the upper portion of the branch portion due to its own weight and flows down from the upper side of the roof 100 to the lower side so that the cooling water can stay in the space as far as possible, It is possible to obtain an effect of improving the cooling power by the heat source.

The injector 20 according to the present invention may be constructed such that the roof 100 can be stably injected with coolant in a spaced space corresponding to the upper part of the roof 100 and the lower part of the solar cell module, The upper part of the injector 20 is fastened to the lower portion of the injector 20 and the lower part of the injector 20 is fastened to the roof 100 by the support 70 fastened to the upper part of the roof 100. However, The support 70 may be rotatable by a driving member (not shown) so that the sprayer 20 can be rotated with respect to the roof 100.

That is, the lower part of the support 70 is fixedly coupled to the roof 100 and the injector 20 is fastened to the roof 100. However, when a certain part of the support 70 or the support 70 is fastened to the injector 20 And is rotatable by a driving member such as a motor.

At this time, the driving member and the supporting unit 70 or the coupling unit can be configured in various forms as long as the belt or the gear is engaged and the rotational force of the driving member can be transmitted to the support 70 or the coupling unit. The injector 20 rotates and exerts an effect that the cooling water can be uniformly injected to various portions of the spacing space.

The operation of the cooling device of the roof solar cell module according to the present invention will now be described.

First, the cooling system of the roof solar cell module is installed to cool the solar cell module installed in the roof 100 of the housing, and the roof 100 has a rectangular shape which is inclined with respect to the housing column.

The cooling water tank 10 is installed on the ground adjacent to the housing and the injector 20 is installed on the lower part of the roof 100 corresponding to the eaves of the roof 100. At this time, the injectors 20 are respectively installed at portions corresponding to both vertexes of the lower end of the rectangular roof 100, and the blow induction type duct 50 provided in each of the injectors 20 is arranged at the center of the upper part of the roof 100 And diagonally upward.

The sirocco fan provided in the air blowing chamber 21 of the injector 20 is connected to the rotary shaft of the sirocco fan driving device provided at one side of the injector 20 (opposite to the inlet) and rotated. At this time, the suction portion 22 is located in the sky direction opposite to the roof 100, and the air sucked into the suction portion 22 is sent without interference in a direction perpendicular to the suction portion 22, It is not necessary to provide a switching device for transmitting at right angles, so that a strong wind can be generated because no elements for lowering wind power are generated.

In addition, since the warm air guiding vane 23 and the half guiding vane 24 are provided in the ventilation chamber 21 equipped with the sirocco fan, the wind sent from the sirocco fan can be uniformly directed toward the spray nozzle 40 , It is possible to more uniformly transfer the cooling water sprayed from the spray nozzle 40 by blocking the wind blowing room to the maximum. At this time, by adjusting the installation depths of the warm guide vane 23 and the half guide vane 24 for more precise adjustment, the direction and the spray amount of the cooling water injection can be controlled very precisely.

In addition, in the present invention, since the blow induction type duct 50 mounted on the upper side of the injector 20 through the fastening hole 25 is provided so as to inject the cooling water while maintaining the spraying force for the distance of the spacing space, The cooling water sprayed through the spray nozzle 40 provided in the induction duct 50 is sprayed to the spacing space located farthest from the sprayer 20 through the air induction vanes 52, It is possible to prevent the loss of the coolant of the coolant as much as possible.

In order to precisely control the direction and the distance of the cooling water to be sprayed, the blowing guide 25 of the blowing guide vane 52 is loosened and the blowing guide vane 52 is moved in the direction of the long hole 26 And then the fastener 25 is fixed.

The cooling water supply pipe 11 is vertically installed along the outer surface of the air induction duct 50 and the induction pipe 57 is connected to the air induction duct 50 The cooling water is sprayed to the spray nozzle 40 through the induction pipe 57 along the cooling water supply pipe 11. In this case,

Accordingly, the cooling water is sprayed to the uppermost space through the ventilation chamber 21 and the ventilation induction duct 50 to the spacing space located farthest from the injector 20 without any desired amount of cooling water.

The cooling water injected from the injector 20 is sprayed to cover the entire space of the roof 100 and is formed into a water droplet form on the upper surface of the roof 100. The cooling water formed in the shape of water droplets is discharged to the lower end of the roof 100 The cooling water is collected in the cooling water receiver 60 provided at the lower end of the branch portion, and the collected cooling water is reintroduced into the cooling water tank 10 after the foreign substances are removed by the water purification apparatus.

In addition, when the sprayer 20 is installed so as to be rotatable by the driving member, the operator may spray the cooling water by adjusting the spraying direction as necessary by using a wireless communication capable of operating the driving member. At this time, it will be obvious that the operator can adjust the spraying direction of the sprayer 20 by using the remote controller interlocked with the wireless communication.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. And various changes can be made without departing from the scope of the invention.
