Description
Technical Field
The present invention relates to an air thermal-arrest PVT thermal collector, and more particularly, to an air thermal-arrest PVT thermal collector which simultaneously performs electric power generation based on light reception of a solar light source and thermal power generation based on transmission heat arrest of a solar light source, thereby being capable of effectively producing electric power as an energy resource required for life and a heat source required for heating.
Background
In general, power generation using solar energy includes solar power generation in which solar light or solar heat is converted into electric energy, solar heat collection power generation in which solar heat from a solar light source is concentrated and then used for heating or hot water, and various types of Photovoltaic (PV) modules having a power generation structure based on such solar energy are developed and used.
However, the solar photovoltaic module generates heat during power generation to increase its temperature, and thus becomes a cause of lowering power generation efficiency. That is, when the solar photovoltaic module is crystalline, only about 12 to 16% of energy incident from the sun is used for power generation, the utilization efficiency of solar energy is very low, and the remaining energy is entirely consumed thermally, thereby increasing the temperature of the solar power generation cell, which is affected by the increase in temperature, and there is a problem in that the power conversion efficiency at the time of power conversion is lowered due to the characteristics of the cell.
Therefore, the solar photovoltaic power generation module is configured to discharge waste heat after a structure for heat dissipation is provided on the rear surface, thereby reducing the temperature of the solar photovoltaic power generation module and improving the electrical performance of the system.
Under such circumstances, a photovoltaic-thermal (PVT) power generation module has been developed and used to effectively utilize hot air generated during the power generation process of a solar photovoltaic power generation module so as to be able to utilize solar light and solar heat at the same time, thereby being able to be utilized for hot water supply or heating.
As a prior art disclosing a solar/thermal power generation module as described above, korean laid-open patent publication No. 999955 (12 months and 03 days 2010) discloses an air heat collecting type solar power generation apparatus including: a solar power generation module arranged on the roof or the outer wall of the building for absorbing solar energyThe source is converted into electric energy to generate electric power, and a plurality of batteries are connected; a frame adhered to a rear surface of the solar photovoltaic module to partition the solar photovoltaic module from a roof or an outer wall of a building, forming an air-receiving space therebetween, and having an air inlet; a heat conductive adhesive applied to a back surface of the solar photovoltaic module; a heat radiation plate which is bonded to the solar photovoltaic module with the heat conductive adhesive and discharges heat generated from the solar photovoltaic module to air contained in the containing space; a plurality of heat dissipation pins which are adhered to the back surface of the heat dissipation plate so that heat discharged from the heat dissipation plate can be easily discharged; and an air collector received in the receiving space to collect heated air for hot water supply or heating, wherein the heat dissipation pin is formed by bending a metal plate having a length corresponding to a width or a height of the solar photovoltaic module
Or
And a shape formed by bonding the solar photovoltaic module to the heat sink so as to be adjacent to each other, and bonding the solar photovoltaic module to the heat sink by a heat conductive adhesive, wherein the outer frame has a height such that the back surface of the solar photovoltaic module is spaced apart from the outer surface of the roof of the building or the outer surface of the outer wall of the building by 10 to 15cm, thereby obtaining a cooling effect of the solar photovoltaic module and a high heat source.
However, although the conventional technology described above has a problem that the efficiency of generating electricity by solar power generation is high because a plurality of cells are applied to the entire area of the solar photovoltaic power generation module, the efficiency of producing heat sources for using heat is low because only heat sources generated during power generation in the solar photovoltaic power generation module are transmitted.
Further, since a heat radiating plate to which a plurality of heat radiating pins are attached is conventionally provided in a photovoltaic module, there is a problem that a load is applied to the photovoltaic module due to a large weight, and durability is low, such as a sagging phenomenon.
Further, since a heat-conductive adhesive has been used for attaching a heat sink to a photovoltaic module, there is a problem that contact resistance between the photovoltaic module and the heat sink is generated by the adhesive, and heat transfer performance is remarkably reduced.

The outer frame (10) supports the solar module (20) and the heat collecting plate (30) so as to be disposed at respective positions, and is configured to form a sidewall at four sides along an outer edge of the solar module (20).
The outer frame (10) is made of a metal material such as aluminum or a material such as plastic as a heat insulating material.
An air bag space (15) capable of accommodating air is formed inside the outer frame (10). That is, since the solar module (20) is provided on the upper portion of the outer frame (10) and the insulating plate (40) is provided on the lower portion of the outer frame (10) to close the upper surface and the lower surface of the outer frame (10), respectively, an air pocket space (15) capable of accommodating air is formed inside the outer frame (10).

The solar module (20) is disposed on the upper portion of the outer frame (10) and has a structure in which the upper surface is exposed to the outside, so that the solar module can be directly contacted with sunlight.
As shown in fig. 1 and 2, the solar module (20) includes a light-receiving/power-generating section (21) for absorbing sunlight to generate electric energy, and a light-transmitting section (25) for transmitting sunlight to the air pocket space (15).
The light receiving/power generating unit (21) includes a battery assembly having a structure in which a plurality of solar cells (22) that generate electric energy by receiving light from a solar light source are connected in a row in the width direction of the solar module (20).
The battery assemblies are arranged at intervals in the longitudinal direction of the solar module (20). That is, the light-receiving/power-generating unit (21) has a structure in which battery assemblies connected in a row as shown in fig. 2 are arranged at intervals in the longitudinal direction, and is configured to include a plurality of battery assemblies.
The light transmitting part (25) transmits the sunlight through the air pocket space (15) so that the sunlight can directly contact the heat collecting plate (30), and the light transmitting part (25) is formed between each of the light receiving and power generating parts (21).

As shown in fig. 4, the heat collecting plate (30) is configured to follow an incident angle of sunlight directed toward the solar module (20), and is adjustable in angle in a left-right rotation direction.
Although not shown, when the rotation angle of the heat collecting plate (30) is driven to be adjustable, a speed reducer and a motor for rotation driving are mechanically coupled to one end of the heat collecting plate (30), and a tracking means for tracking the position of the sun is further provided so that an input signal with respect to the incident angle of the sunlight can be applied.
The tracking means may be configured to be equipped with a camera module that detects the shape of the sun based on an image signal of the sun and can detect the position based on the movement coordinate of the sun, or may be configured to be equipped with a timer for detecting the position of the sun in each time zone based on a time input signal.
As described above, the heat collecting plate (30) is configured to track the incident angle of the sun when the rotation angle is adjusted, thereby increasing the incident amount of the sunlight and further improving the heat collecting efficiency.
