Description

PVT composite panel for solar power generation

The present invention relates to a PVT composite panel for solar photovoltaic power generation, and more particularly, to a PVT composite panel that minimizes thermal resistance between each of the heating medium components such as a PV panel and a solar absorption plate, thereby improving durability and performance To a PVT composite panel having a compact appearance by reducing the overall weight and volume.

Generally, solar power generation includes solar power generation that converts sunlight or solar energy to electric energy, and solar heat collection power for heating or warming the solar light source after collecting the solar heat source. Various photovoltaic (PV) modules have been developed and used.

However, since the solar cell module generates heat during the electricity production process and raises the temperature of the solar cell module, there is a disadvantage that the electricity production efficiency can not be increased beyond a certain level. That is, in the case of the crystalline solar cell, only 12 to 16% of the energy input from the sun is used for power generation, so that the efficiency of utilization of solar energy is considerably low and all the remaining energy is consumed as heat, The temperature of the cell is increased to affect the performance and durability of the cell, and there is a problem that the electric conversion efficiency is reduced when the electric energy is converted due to the temperature rise due to the cell characteristics.

Accordingly, in the case of the photovoltaic power generation module, waste heat is discharged after a configuration for ventilating the heat is provided on the rear surface, and the electric performance of the system is improved as the temperature of the photovoltaic generation module is lowered.

In this background, a PVT module (photo-voltaic-thermal) module that can efficiently utilize the heat generated during the electricity production process of the PV module and utilize it for hot water supply and heating, Has been developed and used.

As a technology related to the solar / thermal power generation module, for example, there is a solar power generation module installed on a roof or an outer wall of a building, absorbing solar energy and converting it into electric energy to generate electricity, An outer frame attached to the outer surface of the rear surface of the solar power generating module and having a solar power generating module and a roof or an outer wall of the building to form a receiving space for receiving air therebetween and having an air inlet, A heat radiating plate attached to the solar power generating module by the thermally conductive adhesive and radiating heat generated from the solar power generating module to air contained in the receiving space; A plurality of heat dissipating fins attached to facilitate the heat dissipation from the heat dissipating plate; Wherein the solar cell module is mounted on the outer surface of the roof of the building or on the outer surface of the outer wall of the building, and the air collector collects the heated air accommodated in the accommodation space, And a height for allowing the solar cell module to be separated from the solar cell module, so that a cooling heat of the solar module and a high heat source can be obtained.

However, the conventional technology related to the photovoltaic / thermal power generation module applies a plurality of cells to the entire area of the photovoltaic power generation module, so that the electric power generation efficiency due to the photovoltaic power generation is high. On the other hand, Since only the heat source is conducted, the heat source production efficiency for heat use is insignificant, and since the heat sink having a plurality of heat dissipating fins is used for heat dissipation, the weight and volume of the solar module become large, There is a problem that the durability is lowered.

In addition, since a thermally conductive adhesive is used to attach the heat sink to the solar module, there is a problem that the contact resistance due to the adhesive is generated between the solar module and the heat sink, thereby significantly deteriorating heat transfer performance.

It is an object of the present invention to minimize the thermal resistance between the respective heating element components such as the PV panel and the solar absorbing plate constituting the PVT composite panel to improve durability and performance and to reduce the overall weight and volume, To provide a PVT composite panel for solar thermal power generation.

In order to achieve the above object, a PVT composite panel for solar photovoltaic power generation according to the present invention comprises a PV panel for receiving sunlight to generate electric energy, a solar absorbing plate provided below the PV panel for absorbing heat energy, And a heat insulating material disposed at a lower portion of the solar cell to form a thermal energy transmitting means for transmitting heat energy absorbed from the solar heat absorbing plate and intercepting the loss of the thermal energy, wherein the PV panel and the solar heat absorbing plate are laminated to each other, As shown in Fig.

The PVT laminated unit may be laminated with the PV panel and the solar absorbing plate insulated from each other by an insulating film.

A transparent film may be laminated on the upper surface of the PVT laminated unit.

The heat energy transmission means may be formed on the upper surface of the heat insulating material in the form of a liquid flow path or an air flow path.

The heat energy transmission means may be a circular or semicircular flow path whose top surface is open, and the open top surface may be formed in a close contact with the bottom of the solar absorption plate.

The heat energy transmitting means may be formed in a shape of an air pocket having an inverted trapezoidal cross section and the long side of the inverted trapezoid is in close contact with the lower part of the solar absorbing plate.

The PVT composite panel for solar photovoltaic generation may further include a case having a heat radiation window formed on one side thereof and communicating with the heat energy transmission means.

A heat radiation cover for opening / closing the heat radiation window may be further formed on one side of the case having the heat radiation window.

A heat radiation cover opening / closing means for opening / closing the heat radiation cover may be further formed on the inner heat insulation material on one side where the heat radiation window of the case is formed.

The heat dissipation cover opening / closing means may include a mounting portion having a structure in which the heat dissipating cover opening / closing means is fixed to an edge portion formed by the upper surface and the side surface of the heat insulating material and is fixed to one side of the heat dissipating cover. And may include protrusions.

The

PV panels

110 and 120 may be laminated in a state where the PV panels 110 and the solar absorption panels 120 are insulated from each other by the insulation film 130. At this time, the insulating film may be made of polyethylene, polypropylene, polyurethane, or ethylene vinyl acetate (hereinafter, referred to as " ethylene-vinyl acetate ") having excellent transparency, impact resistance, cold resistance, chemical resistance, ) May be used as the insulating film.

In addition, the

PVT lamination units

110, 120, and 130 may have a structure in which a transparent film 116 is laminated on the upper surface. That is, by laminating and bonding a transparent film 116 such as a vacuum glass or a special film resistant to ultraviolet rays as a transparent protective cover on the upper surfaces of the

PVT laminate units

PVT stacking unit

110, 120, 116b. The upper transparent film 116 and the lower transparent film 116b are formed on the outer circumferential surface of the insulating film 130 of the

PVT stack unit

films

120 and 120.

PVT lamination units

110, 120, and 130 can be provided.

The heat energy transmission means 141 and 143 may be formed on the upper surface of the heat insulating material 140 in the form of a liquid flow path or an air flow path. Specifically, the heat transmission means 141 and 143 may be circular or semi-circular, A heat energy transmission means 141 formed in a structure in close contact with the lower part of the absorption plate 120 or an air pocket having an inverted trapezoidal shape in cross section is formed in a structure in which the long side of the inverted trapezoid is in close contact with the lower part of the solar absorption plate 120 The heat energy transfer means 143 may be formed.

Specifically, the heat energy transmission means 141 and 143 are installed under the solar absorption plate 120 so that a heating medium to which thermal energy of the solar absorption plate 120 can be transmitted circulates therein. In this case, since the heat medium circulates the heat energy of the solar absorbing plate 120 so that it can be utilized as a source of energy, the heat energy transmission means 141 and 143 are extended toward the heating or hot water facility Structure is preferable.

The thermal energy transmission means 141 and 143 are constructed in such a manner that the circular or semicircular flow path type thermal energy transmission means 141 and the thermal energy transmission means 143 in the form of air pockets having an inverted trapezoidal cross- Heat energy transmission means 141 and 143 may be used.

8, the heat energy transmission means 141 and 143 are provided in the heat insulating material 140 between the heat energy transmission means 143 having the shape of an air pocket having an inverted trapezoidal cross section in the shape of circular heat energy transmission means The PVT composite panel 100 may be formed in a structure in which heat transfer efficiency and heat radiation characteristics of the PVT composite panel 100 can be improved at the same time.

The PVT composite panel 100 for solar photovoltaic generation may further include a case 150 on one side of which a heat dissipation window 151 communicating with the heat energy transmission means 141 and 143 is formed. When the heat dissipation window 151 is at such a level as to cause damage or deformation of the PVT composite panel 100 due to excessive thermal energy generated from the

PVT stacking units

110, 120 and 130, the thermal energy transmission means 141 And 143 can be discharged to a certain extent outside, thereby achieving thermal stability of the PVT composite panel 100 and achieving stable energy production efficiency. Here, a transparent case cover 156 may be formed on the upper surface of the case 150 to close the case 150 at a predetermined distance from the

PVT stacking units

110, 120, and 130.

It is preferable that a heat radiating cover 152 for opening and closing the radiating window 151 is further formed on one side of the case 150 on which the radiating window 151 is formed. That is, the PVT composite panel 100 for solar photovoltaic generation can generate electricity stably without affecting the physical properties and performance of the PVT composite panel 100, because the thermal energy generated from the

PVT stacking units

110, 120, The heat dissipation cover 152 closes the heat dissipation window 151 to maximize the energy production effect and the thermal energy generated from the PVT stacking units 110, The PVT composite panel 100 may be damaged or deformed by opening the heat radiating cover 152 and discharging excessive heat energy to the outside of the PVT composite panel 100 to improve the stability and reliability of the PVT composite panel 100. [ .

A heat dissipation cover opening / closing means 160 for opening / closing the heat dissipation cover 152 may further be formed on the inner heat insulator 140 on one side where the heat dissipation window 151 of the case 150 is formed. The heat dissipation cover opening and closing means 160 may include a mounting portion 161 having a structure in which the heat dissipating cover opening and closing means 160 is closely attached to and fixed to an upper surface and a side surface of the heat insulating material 140, And a protrusion 162 extending to be able to open and close the cover 152 and to be in contact with one surface of the heat radiating cover 152. The heat dissipation cover 152 is installed on one side of the case 150 by a connection portion such as a hinge connection member 152a for example. By the movement of the heat dissipation cover opening / closing means 160, (Not shown).

The heat radiating cover opening and closing means 160 including the mounting portion 161 and the protruding portion 162 is configured such that the heat insulating material 140 having the heat energy transmitting means 141 and 143 is heated by the heat energy transmitting means 141 and 143, The mounting portion 161 closely attached to the corner portion of the heat insulating material 140 is pushed outward due to the thermal expansion of the heat insulating material 140 and moves naturally when the thermal cover 160 is thermally expanded. The heat dissipation cover 152 is moved outwardly by moving the protrusion 162 contacting the one surface in the outward direction so that the heat dissipation window 151 is opened, It is possible to smoothly discharge the excessive heat energy to the outside.

The heat energy transfer means 141 and 143 having the excessive heat energy discharged to the outside are again in a thermal equilibrium state so that the temperature of the heat insulating material 140 is lowered again and the volume of the heat insulating material 140 is contracted The mounting portion 161 and the protruding portion 162 are moved inward to be disposed at their original positions so that the heat radiating cover 152 is in a state of closing the heat radiating window 151. [ The PVT composite panel 100 in which the heat-dissipating window 151 is closed can transmit heat energy again through the heat-energy transmitting means 141 and 143 to smoothly produce energy again.

That is, the heat dissipation cover opening / closing means 160 can maintain a stable thermal state of the PVT composite panel 100 through a simple structure in place of a separate sensor or a complicated cooling device, There is an advantage to make.
