Technical Field

[0002] Photovoltaic modules are a type of power generation device that generates direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Their typical advantages are energy conservation and environmental protection, and they are not restricted by geographical location, so they are widely used in production and life.
[0003] Photovoltaic modules generally absorb the sun's light energy and convert it into environmentally friendly electricity. However, while the sun radiates light energy, it also continuously releases heat energy. Especially in summer, the high temperature is unbearable, and photovoltaic modules have to accept heat energy while receiving light energy. However, when the temperature is too high, it will affect the photoelectric conversion effect of the photovoltaic modules, and even cause the modules to be damaged.
[0004] Therefore, there is an urgent need for a photovoltaic module with a cooling function to solve the above problems. Utility Model Content

[0012] Preferably, the rotating motor and the temperature sensing device are electrically connected.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] (1) Since the thermal conductivity of the heat conducting device is excellent, the heat of the photovoltaic module body is absorbed by the heat conducting device and then dissipated through the heat dissipation component, thereby achieving a physical cooling effect, ensuring the photoelectric conversion effect of the photovoltaic module body and protecting the photovoltaic module body from high temperature damage.
[0015] (2) By sensing the temperature of the heat conducting device through the temperature sensing device, the heat dissipation component can be started or stopped according to the actual temperature, thereby preventing the heat dissipation component from doing ineffective work and causing waste of electrical energy.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-8 , the utility model provides embodiments:
[0028] A photovoltaic module with a cooling function includes a photovoltaic module body 1. The photovoltaic module body 1 is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials. The photovoltaic module body 1 can convert the absorbed light energy generated by the sun into energy-saving and environmentally friendly electric energy. However, while absorbing the light energy of the sun, the photovoltaic module body 1 inevitably also absorbs the heat energy of the sun. Therefore, a cooling function needs to be added for protection.
[0029] Figure 1 It can be seen that the four sides of the photovoltaic module body 1 are connected with a protective frame 2, and grooves are opened in the middle of the four sides of the protective frame 2. The photovoltaic module body 1 is fixedly connected with the protective frame 2 in the inner groove of the protective frame 2. The function of the protective frame 2 is to protect the corners of the photovoltaic module body 1 from damage, and at the same time provide a support point for the cooling mechanism below while not occupying the heating area of the photovoltaic module body 1 as much as possible.
[0030] The settings of the protection border 2 are as follows Figure 4The heat-conducting device 3 shown is made of aluminum profile. The purpose of using aluminum profile is to reduce the production cost of the cooling mechanism under the premise of ensuring thermal conductivity. The four sides of the heat-conducting device 3 are fixed to the protective frame 2. A connecting plate 4 is arranged below the heat-conducting device 3. The protective frame 2 and the connecting plate 4 are fixedly connected by fixing bolts. The heat-conducting device 3 is located between the photovoltaic component body 1 and the connecting plate 4, and the smooth surface of the heat-conducting device 3 is bonded to the photovoltaic component body 1 through silicone. The heat sink surface of the heat-conducting device 3 is against the connecting plate 4. Through the fixed connection between the connecting plate 4 and the protective frame 2, the heat-conducting device 3 is better in contact with the photovoltaic component body 1 and absorbs the heat accumulated in the photovoltaic component body 1. The application of silicone can help the heat-conducting device 3 absorb the heat energy in the photovoltaic component body 1 better, faster and more fully.
[0031] Figure 3 In the figure, a heat dissipation component 5 and a temperature sensing device 6 are arranged in the connecting plate 4, and the heat dissipation component 5 includes a fan frame 51. A circular through hole and a square through hole are opened on the upper and lower sides of the connecting plate 4. The fan frame 51 is sleeved in the circular through hole of the connecting plate 4, and the temperature sensing device 6 is sleeved in the square through hole of the connecting plate 4. A support frame 52 and a protective cover 55 are fixedly connected in the middle of the fan frame 51. The back surfaces of the support frame 52 and the protective cover 55 are flush with the upper and lower surfaces of the fan frame 51 respectively. The support frame 52 and the temperature sensing device 6 are against the heat sink of the heat conducting device 3. A rotating motor 53 is fixedly connected to the side of the support frame 52 facing the protective cover 55. The rotating motor 53 and the temperature sensing device 6 are fixedly connected to the heat sink 51. The temperature sensing device 6 is electrically connected, and the output end of the rotating motor 53 is fixedly connected with the fan blade 54. The rotating motor 53 and the fan blade 54 are between the support frame 52 and the protective cover 55. Through the contact between the temperature sensing device 6 and the heat conducting device 3, the stability of the heat conducting device 3 can be sensed. When the temperature of the heat conducting device 3 reaches the warning value, the temperature sensing device 6 will control the rotating motor 53 to work, drive the fan blade 54 to rotate, and dissipate the heat on the heat conducting device 3, thereby achieving a more sufficient cooling effect. The function of the temperature sensing device 6 is to control the rotating motor 53, and the purpose of the temperature sensing device 6 is to prevent the rotating motor 53 from idling and wasting the electrical energy converted by the photovoltaic component main body 1.
[0032] Working principle: When installing the photovoltaic component, first place the heat-conducting device 3 behind the photovoltaic component body 1 and fix it to the protective frame 2. At the same time, apply silicone on the contact surface between the photovoltaic component body 1 and the heat-conducting device 3 to ensure that the heat-conducting device 3 can more fully absorb the heat in the photovoltaic component body 1. Then fix the connecting plate 4 to the protective frame 2, cover the heat-conducting device 3 to prevent it from falling off, and insert the fan frame 51 and the temperature sensing device 6 into the corresponding through holes in the connecting plate 4.
[0033] When the heat conducting device 3 absorbs enough heat to reach the warning value, the temperature sensing device 6 will sense it and then control the rotating motor 53 to start working. The rotating motor 53 drives the fan blades 54 to rotate, dissipating the heat in the heat conducting device 3 and helping the photovoltaic module body 1 to cool down.
