Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air collecting type PVT collector,

The present invention relates to an air collecting type PVT collector, and more particularly, to an air collecting type PVT collector. More particularly, the present invention relates to an air collecting type PVT collector, And an air-driven PVT collector capable of efficiently producing a heat source necessary for heating.

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, the PV module generates heat during the electric production process, thereby raising the temperature of the PV module, thereby deteriorating the electricity production efficiency. 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, There is a problem in that the temperature of the cell is increased and the electric conversion efficiency is reduced when the electric energy is changed due to the temperature rise due to the cell characteristics.

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

In this background, a PVT module (photo-voltaic-thermal) module that can efficiently utilize the heat generated during the electric production process of the PV module to utilize the solar and solar heat simultaneously, Has been developed and used.

As a conventional technique disclosed in relation to the above-described solar / thermal power generation module, Korean Patent Registration No. 999955 (Dec. 3, 2010) discloses a solar power generation device, which is installed on a roof or an outer wall of a building, A solar cell module connected to the outside of the solar cell module and separated from the roof or outer wall of the solar cell module and the building, An outer frame having an air inlet and forming a receiving space for receiving air, a thermally conductive adhesive applied to the back surface of the solar power generating module, and a thermally conductive adhesive attached to the solar power generating module by the thermally conductive adhesive, A heat radiating plate for radiating heat generated from the photovoltaic module to air contained in the accommodating space; A plurality of heat dissipating fins for facilitating the discharge of heat radiated from the solar battery module, and an air collector for collecting heated air accommodated in the accommodating space for hot water supply or heating, A metal plate having a length corresponding to a width or a height of the metal plate is formed by bending the metal plate in a 'or' form and attached to the heat radiating plate so as to be adjacent to each other, the heat radiating plate being attached to the heat radiating plate with a thermally conductive adhesive, The solar power generating module is constructed to have a height such that the back surface of the solar power generating module is spaced apart from the outer surface of the building roof or the outer surface of the building outer wall by 10 to 15 cm, Photovoltaic devices are known.

However, in the case of the above-mentioned prior art, since a plurality of cells are applied to the entire area of the photovoltaic power generation module, the electric power generation efficiency due to solar power generation is high. On the other hand, So that there is a problem that the heat source production efficiency for heat use is insufficient.

In addition, conventionally, since a heat sink having a plurality of heat dissipation fins is formed on a solar power generation module, there is a problem that durability is weak, such as a load is applied to a solar cell module due to a large weight.

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