Detailed Description

As shown in fig. 1, a respiration hole device of a flat-plate solar collector comprises a circular truncated cone structure 1, a square structure 2, a square hole 3 on the circular truncated cone structure 1, and a square hollow cavity 4 in the square structure 2.

As shown in fig. 2 and fig. 6, a square hole 3 is formed on a circular truncated cone structure 1 of the breathing hole device, and a square hollow cavity 4 is formed on a square structure 2 shown in fig. 3; as shown in fig. 4 and 5, the square hole 3 on the circular truncated cone structure 1 is communicated with the square hollow cavity 4 on the square structure 2; as shown in fig. 7, the breathing hole device is installed on the frame 5 of the heat collector in the practical application process, and as shown in fig. 7, the breathing hole device is installed on the two side frames 5 of the heat collector in the practical use process; the side frame 5 of the heat collector is provided with a square mounting hole 7 as shown in figure 9.

As shown in fig. 8, a square hollow cavity 4 in a square structure 2 of the breathing hole device is communicated with the inner side of a cavity of the heat collector, and a square hole 3 on a round platform structure 1 is communicated with the outer side of the cavity of the heat collector; when the temperature of the heat collector rises, the volume expansion pressure of air in the cavity of the heat collector rises and hot air rises simultaneously, and the air forms convection with the air outside the cavity of the heat collector through the square hollow cavity 4 and the square hole 3, so that high-temperature moisture in the heat collector is removed out of the heat collector in time, the water mist on the surface of the cover plate of the heat collector is rapidly eliminated, and the photo-thermal conversion performance of the heat collector is improved.

As shown in fig. 8 the utility model discloses installation clearance L between breather hole device round platform structure 1 and the square structure 2 is less than the wall thickness t of heat collector frame 5, makes the formation interference fit between breather hole device and the heat collector frame, prevents that the rainwater from getting into in the heat collector cavity through the installation hole.

As shown in figure 10, the installation angle between the flat-plate solar collector and the horizontal plane is α, the angle between the opening direction of the square hole 3 and the square structure 2 is α by adjusting the angle position relation between the opening direction of the square hole 3 and the square structure 2 in the injection molding process of the breathing hole device, the opening direction of the square hole 3 of the breathing hole device can always face to the lower side of the horizontal plane in the use process of the heat collector, rainwater and the like can be prevented from entering the heat collector, meanwhile, the heat loss at the breathing hole due to too direct air convection can be prevented, the problem that the opening direction of the square hole 3 on the breathing hole device is changed due to the fact that the breathing hole device rotates on the heat collector frame in the transportation process can be prevented due to the combined action of the square structure 2 on the breathing hole device and the upper mounting hole 7 on the heat collector frame 5, and the reliability of the breathing hole device in the actual use process is improved.
