In a preferred embodiment of the present invention, the plurality of heat transfer sections 30 spaced apart and surrounded by the closed extension 31 have an odd number of heat transfer sections 30, and the heat transfer section 30 at the other opposite end of the corresponding closed extension 31 has an even number of heat transfer sections 30. In addition, the Pulse Heat Pipe (PHP)3 is a hollow metal pipe, the material and the pipe diameter can be adjusted according to the requirement of heat transfer, in a preferred embodiment of the present invention, the Pulse Heat Pipe (PHP)3 can be made of copper pipe with an outer diameter of 3mm and an inner diameter of about 2mm, so as to achieve a design with light and thin thickness tendency. In addition, in the embodiment of the present invention, in the metal pipe of the pulse type heat pipe (PHP)3, a working liquid is filled as a transmission medium of the heat source; wherein the working fluid may be pure water.
Next, please refer to fig. 2, which is a schematic perspective view of the pulse type heat pipe module according to the present invention. As shown in fig. 2, a portion of the Pulse Heat Pipe (PHP)3 at the even-numbered end 33 of the condensing part is connected to a heat storage tank 2; the heat storage tank 2 is a tank body storing Phase Change Material (PCM) therein, which may be solid-liquid Phase Change Material, such as: the phase change material can be selected from paraffin, polyethylene glycol, calcium chloride, sodium sulfate, sodium carbonate, sodium thiosulfate, sodium phosphate, potassium phosphate, magnesium nitrate, magnesium chloride, barium hydroxide hydrate or acetamide. It is particularly emphasized that the phase change material of the present invention has the property of absorbing heat when it is in a solid state, and when it is heated and reaches the phase change temperature, it will change from a solid state to a liquid state after absorbing heat energy; when the phase change material cools, it returns to a solid state.
Referring to fig. 2, the heat storage tank 2 has a chamber 20 therein, and an injection port 200 is provided for injecting the phase change material into the chamber 20, and the injection port 200 is sealed by a cap 21. In the embodiment of the present invention, first, the condensing part of the Pulse Heat Pipe (PHP)3 is connected to a heat storage tank 2 by disposing a part of the Pulse Heat Pipe (PHP)3 at the even end 33 of the condensing part in the heat storage tank 2, and each of the heat transmission sections 30 arranged at intervals of the condensing part is in contact with a Phase Change Material (PCM). Therefore, the absorbed heat source can be transferred to the heat storage tank 2 by the working fluid in the Pulse Heat Pipe (PHP)3, so that the Phase Change Material (PCM) in the heat storage tank 2 is changed from a solid state to a liquid state after absorbing the heat source, and thus, the pulse heat pipe module of the present invention has a heat dissipation function. In addition, the volume of the Phase Change Material (PCM) in the heat storage tank 2 can be adjusted to absorb different heat sources. For example, when the heat storage tank 2 having a large capacity is used, the temperature of the solar panel can be lowered more.
Next, please refer to fig. 3 and fig. 4, wherein fig. 3 is a perspective view of a solar panel with a cooling device, and fig. 4 is a perspective view of the solar panel with the cooling device on an X-Y plane. First, as shown in fig. 3, the solar panel with a cooling device of the present invention comprises a solar panel 1, a heat storage tank 2 and at least one pulse type heat pipe 3; wherein: the solar panel 1 generally includes a substrate 10 and a plurality of solar chips 11 disposed in the substrate 10. In the embodiment of the present invention, the substrate 10 may be a rectangular frame, and the solar chips 11 are arranged in the rectangular frame in a matrix manner, so that the solar chips 11 are arranged in a large area to face the sun and irradiate the sun, thereby achieving the purpose of absorbing solar energy.
Next, in the present invention, the pulse heat pipe 3 is bent into a plurality of heat transfer sections 30 arranged at intervals, and is formed by the bent portions 331 of even number of heat transfer sections 30 arranged at intervals, and the other end 32 (also referred to as an evaporation portion) of the corresponding condensation portion is formed by the bent portions 321 of odd number of heat transfer sections 30 arranged at intervals (in other words, the plurality of second bent portions are formed by the bent portions 321 of odd number of heat transfer sections 30 arranged at intervals), and the closed extension section 31 outside the evaporation portion, wherein the closed extension section 31 is used for surrounding the bent portions 321 of odd number of heat transfer sections 30 arranged at intervals of the evaporation portion. The pulsating heat pipe 3 is connected to the substrate 10 of the solar panel 1 at an evaporation portion having an extension 31. A portion of one end 32 of the condensation portion extends into the heat storage tank 2, so that an even number of heat transfer sections 30 arranged at intervals are in contact with the phase change material. After the evaporation part of the impulse type heat pipe 3 is connected to the substrate 10 of the solar panel 1, when the temperature of the solar panel 1 rises, the heat source can be transmitted to the phase change material in the heat storage tank 2 by the circulation of the working liquid in the heat transmission sections 30 arranged at intervals in the evaporation part of the impulse type heat pipe 3, so that the heat source of the high-temperature working liquid can be absorbed by the phase change material, the temperature of the working liquid flowing out of the heat storage tank 2 is reduced, the effect of cooling the solar panel is achieved by the circulation of the working liquid, and the conversion benefit of the solar energy conversion panel can be effectively improved. In addition, in an embodiment of the standard pulsed heat pipe module of the present invention, several groups of pulsed heat pipe modules 3 can be used simultaneously to cool the solar panel 1 with a large area. However, the pulsed heat pipe module 3 with the heat storage tank 2 may be customized according to the area of the solar panel 1, and the solar panel with the temperature reducing device shown in fig. 4 is a schematic perspective view on the X-Y plane, which is not limited by the present invention.

In an embodiment of the present invention, the evaporation portion of the pulse heat pipe 3 is corresponding to the support plate 102 of the solar panel 1, and the evaporation portion of the pulse heat pipe 3 is in contact with the support plate 102, and then the solar panel 1 is arranged at an included angle perpendicular to the horizontal, for example, the included angle is 15 degrees to 25 degrees, so as to obtain a better electric energy conversion efficiency. It is obvious that, as in the foregoing embodiments, when the connection structure shown in fig. 6 of the present invention is used, a better heat dissipation effect and a better electrical energy (power) conversion efficiency can be obtained.
In addition, the evaporation part of the pulse heat pipe 3 can be directly corresponding to the encapsulation layer 100(EVA) of the solar panel 1, so that the heat energy on the solar panel 1 can be taken away more quickly, and a better heat dissipation effect and a better electric energy (power) conversion efficiency can be obtained.
Please refer to fig. 7, which is a schematic cross-sectional view of a solar panel with a cooling device in a Z-Y plane according to the present invention.
