Description

Ultra-thin solar panels heat}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar ultra-thin heat panel, which is composed of an ultra-thin heat panel by evacuating a vacuum tube method as a means for minimizing the loss of solar heat incident in a unit area, and has a heat collecting performance similar to that of a vacuum heat tube. ;

Conventionally, a house heat heat tube made of a vacuum tube is usually used as a means for obtaining high temperature heating water in winter; According to the user's requirements, when the heat collection heat tube is installed in the array group, the space between the vacuum heat tube and the heat tube is fastened so as to be advantageous for the maintenance of vacuum tube fastening or breakage; This leads to solar heat incident in the unit area and also high space use efficiency; In addition, the cost of manufacturing a vacuum heat tube is expensive, which greatly burdens the user; Therefore, in order to solve the above disadvantages, it is possible to minimize the solar heat incident in the unit area, improve the space utilization efficiency, and reduce the manufacturing cost of the vacuum heat tube, and have a similar performance as the vacuum heat tube and at a low cost. How to make it is required;

Therefore, in order to solve the above problems, the present invention replaces the vacuum heat tube, which is advantageous for obtaining relatively high temperature heating water, thereby reducing the space between the heat absorbing plate of FIG. 1 (160) and the glass cover of FIG. To provide a solar ultra-thin heat panel that permits to suppress airflow caused by air and has a non-vacuum and vacuum effect, a conventional vacuum heat tube has a large heat loss in collecting solar light incident on a unit area; In addition, the installation cost is high, the space use efficiency is inefficient in the installation of the vacuum heat tube, and the air flow into the vacuum tube sometimes fails to function; As mentioned above, conventional vacuum heat tubes can be advantageous for obtaining high temperature heating water, but are uneconomical;

Advantageous conditions for obtaining a high temperature water of the conventional vacuum heat tube is a vacuum technology that minimizes the amount of air in the tube is a key material and the material constituting the vacuum tube requires an anti-reflective glass material with excellent light transmittance and the surface of the heat absorption plate is the anti-reflective coating technology Its performance depends; Therefore, the conventional vacuum heat tube has much higher hot water heat collecting efficiency than the conventional flat heat collecting heat panel; The reason is that the transparent glass material constituting the vacuum tube is composed of an antireflective glass cover made of a low iron glass material having excellent light permeability; Therefore, the solar light incident on the vacuum tube is incident on the heat absorbing plate located in the vacuum tube, and the speed of light hits the heat absorbing plate at 300,000Km per second. The heat medium oil in the copper tube is continuously accumulated in the heat accumulator at the top of the heating section through natural convection.

Is generated; At this time, the radiant heat emitted from the heat absorbing plate is vacuumed as a means for suppressing air flow caused by the air in contact with the air; But there is no complete vacuum on earth; Complete vacuum means that no material or particles are present in any particular space; What determines the performance of a house heat heat pipe depends on how close to vacuum it is; The vacuum purpose of the vacuum heat tube is to draw out the air in the vacuum tube to the outside, and the radiant heat emitted from the heat absorbing plate provided in the vacuum tube is a means for preventing heat loss from the outside of the vacuum tube through the airflow of air; The present invention is a means for minimizing airflow caused by air by using a conventional vacuum heat tube as a mirror means for reducing heat loss from the outside through the airflow caused by air from the heat absorbing layer of FIG. As a means for minimizing the amount of air in contact with the surface of the heat absorbing layer (160), the material of the glass cover (140) b adjacent to the heat absorbing layer (160) is shown in FIG. 1 (reflective low iron tempered glass material having excellent light transmission). 140) b The inner cover between the glass cover and the heat absorbing layer of Fig. 1 (160) is allowed to be around 1 mm, and the air volume is minimized to give a narrow space and resist the movement of air flow to suppress heat loss and to prevent heat loss. The space between the glass cover and the glass cover of Fig. 1 (140) b is a glass cover of Fig. 1 (130) as a means for supplementing the thermal insulation of the glass cover of Fig. 1 (140) b by giving an air layer of about 10 mm; The rear part constituting the heating part is made of polyurethane foam material having excellent heat resistance and insulation, and is bonded to the back of the heating part to remove the air layer at the surface of the heating part 1 (180) and at the same time generating airflow due to heat insulation and air. It is done as above to remove and obtain a vacuum effect in a non-vacuum state; In addition, a non-thermally conductive material having a thickness of about 1 mm between the heat absorbing layer of FIG. 1 (160) and the glass cover of FIG. 1 (140) includes a lattice mesh as shown in FIG. Higher vacuum effect can be obtained by the complete isolation; 1 (160) is a heat absorbing layer which is coated with an anti-reflective black paint which absorbs light well on the surface of the absorbing layer and is heat treated at a high temperature as a means for preventing the change of the surface of the heat absorbing layer due to degradation;

The ultra-thin heat panel of the present invention is advantageous to prevent the loss of solar heat incident in the unit area and to obtain a high temperature heating water by obtaining a non-vacuum and vacuum effect, which significantly lowers the manufacturing cost and has a small installation space, thereby increasing the space utilization efficiency; The configuration of a conventional vacuum heat tube array includes; An absorption plate in one vacuum heat tube, consisting of a vacuum heat absorber having a size of 90 mm by 2000 mm; 16 vacuum heat pipes are arranged in a vertical array with the vacuum heat pipes vertically; The area occupied by an array is about 2000 mm wide by 2000 mm long; Therefore, in the present invention, when the size of the heat panel is 2000 mm x 2000 mm in the same area as a conventional vacuum heat tube array, the vertical spatial area will be said to be the same as before; Compared to the method in which 16 vacuum heat tubes are fastened to one vacuum heat tube array when divided into 2000 mm / 90 mm horizontally; The method according to the invention has the effect that about 22 vacuum heat tubes are fastened when executed in the same area; Thus, the heat collection capacity is about 30% higher than that of one vacuum heat tube array composed of a conventional vacuum heat tube; Thus, considering that the method according to the present invention is non-vacuum, it is possible to sufficiently overcome the inferior parts compared to the conventional vacuum heat tube.

That's a shame; It can be seen that the heat collecting effect is superior to the conventional solar vacuum heat tube as described above; More importantly, it can be manufactured at a lower cost than conventional vacuum heat tubes; As such, ultra-thin heat panels similar to those of conventional vacuum heat tubes can be supplied at low cost, thereby greatly reducing the burden on the user, and expanding the use of solar heat, which is a renewable energy, to suppress carbon emissions.
