Non-power cooling type solar panel

摘要

The present invention relates to a solar panel that is cooled without using power, and more particularly, to a solar panel which is cooled without using power and which is naturally cooled by means of ascending air heated in a passage provided in a cooling plate so as to maintain the temperature of the solar panel suitable for the efficient generation of power without requiring a separate power source. For this purpose, the solar panel of the present invention includes: a cell panel including solar cells for converting solar energy into electric energy; and a cooling plate directly or indirectly contacting the back surface of the cell panel so as to transfer heat, the cooling plate having a cooling-air passage which is formed so as to extend vertically within the cooling plate, and the upper and lower ends of which are in contact with the outside air.

主权项

1. A non-power cooling type solar panel, comprising:
a cell panel including solar cells for converting sunlight into electric energy; and a cooling panel installed to be in direct or indirect contact with a back surface of the cell panel, for transfer of heat, the cooling panel including a cooling air channel formed in the cooling panel, to be vertically elongated, while communicating with ambient air at upper and lower ends of the cooling air channel, wherein the cooling panel includes a first refrigerant receiving chamber and a second refrigerant receiving chamber, which are partitioned from the cooling air channel while receiving refrigerant, wherein the first refrigerant receiving chamber and the second refrigerant receiving chamber are connected via a first tube for a flow of an evaporated refrigerant and a second tube for a flow of a condensed refrigerant such that heat of a high temperature region in the cooling panel is transferred to a low temperature region in the cooling panel in accordance with a circulation and phase change of the refrigerant between the first refrigerant receiving chamber and the second refrigerant receiving chamber, and wherein the first refrigerant receiving chamber is located at a side of the cooling panel proximal to the cell panel, and the second refrigerant receiving chamber is located at another side of the cooling panel distal to the cell panel under a condition that the entirety of the cooling air channel is interposed between the first refrigerant receiving chamber and the second refrigerant receiving chamber.
