Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and more specifically to a colored photovoltaic roof component with heat dissipation function. Background Technology

[0002] With the global energy structure transformation and the increasing demand for building energy conservation, Building Integrated Photovoltaics (BIPV) technology has become an important direction for combining renewable energy with building design. Traditional photovoltaic curtain wall systems integrate photovoltaic modules into the building facade to combine solar power generation with building functions.

[0003] Colored photovoltaic modules often achieve their color effects through surface coating or printing processes, but these processes hinder heat dissipation, leading to increased operating temperatures. Studies show that for every 1°C increase in module temperature, power generation efficiency decreases by 0.4%.4 Although some technologies achieve color diversity through replaceable colored films,3 their vent design still struggles to balance heat dissipation requirements with color uniformity, and prolonged exposure to high temperatures can easily cause film peeling or fading.

[0004] Existing heat dissipation devices mostly use cooling fans, which continuously cool the photovoltaic modules. However, ambient temperature varies with the seasons. In cold winters, the low ambient temperature allows the heat generated by the photovoltaic modules to easily dissipate into the air, inevitably leading to energy waste if they continue to operate.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] A colored photovoltaic roofing module with heat dissipation function, combined with Figures 1 to 3 As shown, it includes a photovoltaic module 1 and a PLC controller 19. The PLC controller is used to control the heat dissipation of the photovoltaic module. A heat sink 9 is provided on the back of the photovoltaic module 1 to dissipate heat from the photovoltaic module. The photovoltaic module 1 and the heat sink 9 are respectively provided with an upper frame 2 and a lower frame 4 on the upper and lower sides. The lower frame 4 is provided with ventilation holes 5. Several cooling fans 3 are provided on the upper frame 2 to dissipate heat from the photovoltaic module. The input end of the cooling fan is connected to the output end of the PLC controller.

[0021] The heat sink 9 has a cooling channel 6 inside, which has a serpentine structure. The inlet end of the cooling channel 6 is connected to a cooling water tank 13 through a water inlet pipe 7 to provide a cooling water source. The outlet end of the cooling channel 6 is connected to a water storage tank 16 through a water outlet pipe 8 to store cooling water. A pump 14 is installed on the water inlet pipe 7 to send the cooling water in the cooling water tank into the cooling channel of the heat sink to cool the photovoltaic module and improve the cooling effect of the photovoltaic module.

[0022] A temperature sensor 12 is installed on the back of the heat sink 9 to detect the temperature information of the photovoltaic module. The output of the temperature sensor is connected to the input of the PLC controller.

[0023] Thermally conductive silicone 10 is provided between the photovoltaic module 1 and the heat sink 9, which enables the heat of the photovoltaic module to be conducted to the heat sink for better heat dissipation.

[0024] Heat dissipation fins 11 are provided on the back of the heat dissipation plate 9 to accelerate the heat dissipation of the photovoltaic module. The heat dissipation fins are aligned with the direction of the cooling fan and ventilation holes. When the cooling fan ventilates and dissipates heat, heat dissipation channels can be formed between the heat dissipation fins to accelerate air circulation and improve the heat dissipation effect.

[0025] Multiple water storage tanks 16 are configured, each equipped with a level sensor 15 to detect the water level. A solenoid valve 17 is installed on the pipe connecting the water storage tank 16 to the outlet pipe 8 to control whether water is discharged into the water storage tank. A user pipeline 18 is installed on the water storage tank 16, connecting to users who are using water. Hot water after cooling and heat exchange is available for users. A solenoid valve is installed at the user end of the user management system to control whether water is supplied to users. The output of the level sensor is connected to the input of the PLC controller, and the output of the PLC controller is connected to the input of the solenoid valve.

[0026] A temperature sensor 12 is installed inside the water storage tank 16 to detect the water temperature inside the tank. The water storage tank 16 is connected to the inlet of the cooling water tank 13 via a pipe. A pump is installed on the pipe connecting the water storage tank and the cooling water tank. The output of the temperature sensor is connected to the input of the PLC controller, and the output of the PLC controller is connected to the input of the pump. When the temperature sensor detects a decrease in the temperature inside the water storage tank, water can be added to the cooling water tank through the pump, thus realizing the recycling of cooling water.

[0027] A liquid level sensor 15 is installed inside the cooling water tank 13 to collect the liquid level information of the cooling water in the cooling water tank. The output terminal of the liquid level sensor is connected to the input terminal of the PLC controller.

[0028] In this invention, when dissipating heat from photovoltaic modules, a temperature sensor behind the heat sink detects the temperature of the photovoltaic modules. The PLC controller controls the heat dissipation based on the temperature information detected by the temperature sensor. When the temperature detected by the temperature sensor is low, heat dissipation can be achieved through the heat sink without starting the cooling fan and pump. When the temperature rises, the cooling fan can accelerate air circulation to dissipate heat. When the temperature continues to rise, the pump is started to introduce cooling water into the cooling channel. The cooling water exchanges heat with the heat generated by the photovoltaic modules, thereby improving the cooling efficiency of the photovoltaic modules.
