Technical Field

[0001] The utility model relates to the technical field of solar energy, in particular to a heat dissipation device for a solar energy conversion system. Background Art

[0002] Solar photovoltaic modules are power generation devices that generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials.

[0003] A big problem with solar photovoltaic modules when they are working normally is that they generate heat. Generally, the temperature of solar photovoltaic modules in the open air can reach as high as 70 degrees Celsius. The high temperature will affect the internal circuits, causing the solar cell modules to fail to fully exert their maximum performance.

[0004] To this end, a heat dissipation device for a solar energy conversion system is proposed. Summary of the invention

[0005] The purpose of the utility model is to provide a heat dissipation device for a solar energy conversion system to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a heat dissipation device for a solar energy conversion system, comprising a photovoltaic panel body, a frame is installed on the outside of the photovoltaic panel body, a water inlet pipe is installed on one side of the frame, and a plurality of drainage pipes are evenly connected to the water inlet pipe;

[0007] The cross section of the drain pipe is an isosceles trapezoid, the upper bottom of the drain pipe is close to the photovoltaic panel body, and drainage holes are evenly opened on the inclined surfaces on both sides of the drain pipe, and the central axis of the drainage hole is perpendicular to the inclined surface.

[0008] Preferably, mounting plates are respectively installed at both ends of the drain pipe, and the mounting plates are connected to the frame by bolts.

[0009] Preferably, a plurality of limit plates are evenly arranged on the lower surface of the frame, and the plurality of limit plates are connected to the frame by bolts.

[0010] Preferably, a plurality of clamping protrusions are installed on the limiting plate, and the clamping protrusions are clamped with the lower bottom of the drain pipe.

[0011] Preferably, one end of the drain pipe is open and connected to the water inlet pipe, and the other end is closed.

[0012] Compared with the prior art, the beneficial effect of the utility model is that water can be sprayed on the back of the photovoltaic panel through the water inlet pipe, the drainage pipe and the drainage hole, thereby quickly completing the cooling and heat dissipation of the photovoltaic panel, avoiding the situation where the solar cell module cannot fully exert its maximum performance due to excessive temperature.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0020] See also Figure 1-5 The utility model provides a technical solution: a heat dissipation device for a solar energy conversion system, comprising a photovoltaic panel body 1, a frame 2 is installed on the outside of the photovoltaic panel body 1, a water inlet pipe 3 is installed on one side of the frame 2, and a plurality of drainage pipes 4 are evenly connected to the water inlet pipe 3;

[0021] The cross section of the drain pipe 4 is an isosceles trapezoid, the upper bottom of the drain pipe 4 is close to the photovoltaic panel body 1, and drainage holes 7 are evenly opened on the inclined surfaces on both sides of the drain pipe 4, and the central axis of the drainage hole 7 is perpendicular to the inclined surface.

[0022] like Figure 2 and Figure 4 As shown: mounting plates 6 are respectively installed at both ends of the drain pipe 4, and the mounting plates 6 are connected to the frame 2 by bolts; through the above arrangement, the mounting plates 6 can make the drain pipe 4 more convenient and quick to install on the frame 2.

[0023] like Figure 1 and Figure 3 As shown: a plurality of limit plates 5 are evenly arranged on the lower surface of the frame 2, and the plurality of limit plates 5 are connected to the frame 2 by bolts; through the above arrangement, the limit plates 5 can support the position of the drain pipe 4.

[0024] like Figure 3 and Figure 5As shown: a plurality of clamping protrusions 8 are installed on the limiting plate 5, and the clamping protrusions 8 are clamped with the lower bottom of the drain pipe 4; through the above arrangement, the limiting plate 5 and the drain pipe 4 cooperate with each other, and the support and restriction can be carried out more conveniently and quickly.

[0025] like Figure 2 As shown: one end of the drain pipe 4 is open and connected to the water inlet pipe 3, and the other end is closed; through the above arrangement, it is convenient for moisture to be discharged through the drain hole 7, thereby wetting the lower surface of the photovoltaic panel body 1 for cooling.

[0026] Working principle: First, install the water inlet pipe 3 and the drain pipe 4 under the frame 2 respectively, then clamp the limit plate 5 on the drain pipe 4 through the clamping protrusion 8, and fix the two ends of the limit plate 5 to the frame 2 by bolts. When heat dissipation and cooling are required, the water is discharged into the inside of the drain pipe 4 through the water inlet pipe 3, and then the water is sprayed out through the drain hole 7. Since the drain hole 7 is in an inclined state, the water will be sprayed onto the rear surface of the photovoltaic panel body 1, thereby performing heat dissipation and cooling work on the photovoltaic panel body 1.
