[0036] In order to make the purpose, technical solutions and advantages of the present application more apparent, example embodiments according to the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in this application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this application.

[0037] There are two ways to cool down photovoltaic modules, namely solar thermal integration and water cooling. Solar thermal integration is to transfer the thermal energy of the photovoltaic modules to the heat storage equipment by adding a heat conducting device to the photovoltaic modules for heat energy reuse. However, the cost of the additional heat energy transmission system and heat storage equipment is high, and the solar thermal integration method is not ideal in the season without strong sunlight. There are two ways of water cooling: back water cooling or surface water spraying. The back water cooling method requires laying water cooling circulation pipes on the back of the photovoltaic module, and also requires supporting water chillers, water pumps and other equipment, which requires a lot of construction. The surface water spraying method requires the addition of water spraying facilities and drainage facilities around the photovoltaic modules. In actual use, it will face problems such as lack of targeted water spraying strategies and uneven water spraying positions, resulting in unsatisfactory cooling effects.

[0038] Due to the small construction volume and low investment, surface water spraying has more usage scenarios. In the related art, the common surface water spraying methods are nozzle spraying and robot spraying. In the nozzle spraying method, the nozzles are all set in the gap between the photovoltaic panels. This spraying method cannot guarantee that the areas that need to be cooled are sprayed evenly, and it is easy to have dead corners for cooling, resulting in poor cooling effect in some areas on the photovoltaic modules. The robot spraying method lays rails so that the robot can spray and cool along the rails. This spraying method also has the problems of uneven cooling and lack of cooling strategy, and the cooling effect cannot be controlled.

[0039] First, refer to Figure 1 An example electronic device 100 for implementing the temperature reduction control method and apparatus according to the embodiment of the present application is described.

[0040] like Figure 1 As shown, the electronic device 100 includes one or more processors 102, one or more storage devices 104, an input device 106, and an output device 108, which are interconnected via a bus system 110 and / or other forms of connection mechanisms (not shown). It should be noted that Figure 1 The components and structure of the electronic device 100 shown are merely exemplary and non-limiting. The electronic device may also have other components and structures as needed.

[0041] The processor 102 may be a central processing unit (CPU) or other forms of processing units with data processing capabilities and / or instruction execution capabilities, and may control other components in the electronic device 100 to perform desired functions.

[0042] The storage device 104 may include one or more computer program products, which may include various forms of computer-readable storage media, such as volatile memory and / or non-volatile memory. The volatile memory may include, for example, random access memory (RAM) and / or cache memory. The non-volatile memory may include, for example, read-only memory (ROM), a hard disk, a flash memory, etc. One or more computer program instructions may be stored on the computer-readable storage medium, and the processor 102 may execute the program instructions to implement the client functions and / or other desired functions in the embodiments of the present invention (implemented by the processor) described below. Various applications and various data may also be stored in the computer-readable storage medium, such as various data used and / or generated by the application.

[0043] The input device 106 may be a device used by a user to input instructions, and may include one or more of a keyboard, a mouse, a microphone, a touch screen, etc. In addition, the input device 106 may also be any interface for receiving information.

[0044] The output device 108 can output various information (such as images or sounds) to the outside (such as a user), and can include one or more of a display, a speaker, etc. In addition, the output device 108 can also be any other device with an output function.

[0045] For example, an example electronic device for implementing the temperature reduction control method and apparatus according to the embodiment of the present invention may be implemented as a mobile phone, a computer, and the like.

[0046] Below, we will refer to Figure 2 The temperature reduction control method 200 according to an embodiment of the present application is described. Figure 2 As shown, the temperature reduction control method 200 is applied to a photovoltaic module and may include the following steps:

[0047] In step S210 , the current temperature of the first surface of the photovoltaic module is obtained.

[0048] In step S220 , the current temperature of the first surface is compared with a set temperature, and after determining that the current temperature of the first surface is greater than the set temperature, the current temperature of the second surface of the photovoltaic assembly is acquired.

[0049] In step S230, a cooling strategy is determined according to the current temperature of the second surface and the temperature rise data of the photovoltaic module.

[0050] In step S240, a cooling instruction representing the cooling strategy is sent to a cooling robot, so that the cooling robot cools the photovoltaic assembly according to the cooling strategy.

[0051] In an embodiment of the present application, a cooling control method 200 provides a method for controlling a cooling robot to cool a photovoltaic module according to a cooling strategy. Specifically, the cooling control method 200 determines a cooling instruction representing the cooling strategy based on the current temperature of the second surface and the temperature rise data of the photovoltaic module, and sends the cooling instruction to the cooling robot. On the one hand, the cooling of the photovoltaic module by the cooling robot can ensure that all areas of the photovoltaic module are cooled, eliminating any cooling blind spots. On the other hand, the cooling robot can effectively control the cooling effect by performing cooling according to the cooling strategy.

[0052] In an embodiment of the present application, the current temperature of the first surface of the photovoltaic module is collected by a temperature collection device, and then, in step S210, the current temperature of the first surface collected by the temperature collection device is obtained. The temperature collection device can be a temperature measuring element such as a thermocouple, a thermal resistor, or a thermistor, without limitation. The first surface can be the back or front of the photovoltaic module, and correspondingly, in step S220, the second surface can be the front or back of the photovoltaic module. For ease of description, the following description will be based on the example of the first surface being the back of the photovoltaic module and the second surface being the front of the photovoltaic module.

[0053] In an embodiment of the present application, in step S220, after obtaining the current temperature of the first surface, the current temperature of the first surface is compared with the set temperature to determine whether the current temperature of the first surface is greater than the set temperature. It should be noted that due to the sunlight irradiating the front of the photovoltaic module, there is a certain hysteresis in the temperature transfer from the first surface of the photovoltaic module to the second surface. Therefore, the current temperature of the first surface collected should be lower than the current temperature of the second surface. Therefore, when setting the set temperature in advance, the above hysteresis needs to be considered. For example, the set temperature is 50-55°C, for example, it can be selected as 50°C, 51°C, 52°C, 53°C, 54°C, 55°C, etc., and there is no limitation on this.

[0054] In an embodiment of the present application, after determining that the current temperature of the first surface is greater than the set temperature, the cooling control method 200 includes: sending a movement instruction to the cooling robot, so that the cooling robot moves to the location of the photovoltaic module after receiving the movement instruction. Specifically, when the current temperature of the first surface is greater than the set temperature, it indicates that the back surface temperature of the photovoltaic module is higher. Due to the hysteresis of temperature, the front surface temperature of the photovoltaic module should be even higher. Therefore, it is necessary to move the cooling robot to the location of the photovoltaic module to prepare for cooling the photovoltaic module. The movement instruction to the cooling robot can be sent by wired or wireless means, which is not limited to this.

[0055] In an embodiment of the present application, after determining that the current temperature of the first surface is greater than the set temperature, the cooling control method 200 further acquires the current temperature of the second surface of the photovoltaic module. Specifically, the current temperature of the second surface of the photovoltaic module can be acquired using a temperature acquisition device. The temperature acquisition device can be a thermocouple, thermal resistor, thermistor, or other temperature measuring element, without limitation. Alternatively, the current temperature of the second surface of the photovoltaic module can be acquired using a cooling robot that moves to the location of the photovoltaic module.

[0056] In an embodiment of the present application, after obtaining the current temperature of the second surface, a cooling strategy is determined based on the current temperature of the second surface and the temperature rise data of the photovoltaic module. Specifically, after cooling the photovoltaic module, the temperature of the photovoltaic module will rise due to the influence of the temperature rise data of the photovoltaic module. In order to avoid the temperature after the rise being greater than the set temperature again and requiring a second cooling, when determining the cooling strategy, in addition to considering the current temperature of the second surface, the temperature rise data of the photovoltaic module can also be comprehensively considered. This makes it possible that after cooling the second surface, even if the temperature of the photovoltaic module subsequently rises, the temperature after the rise will not reach the set temperature, thus avoiding the duplication of the second cooling. The temperature rise data can include at least one of the following: light intensity, remaining light duration, and the temperature rise rate of the photovoltaic module. The temperature value of the photovoltaic module after cooling can be calculated based on the temperature rise data such as light intensity, remaining light duration, and the temperature rise rate of the photovoltaic module.

[0057] In an embodiment of the present application, a cooling strategy may include a cooling target temperature, and sending a cooling instruction representing the cooling strategy to a cooling robot so that the cooling robot cools the photovoltaic module according to the cooling strategy includes: sending a cooling instruction representing the cooling strategy to the cooling robot so that the cooling robot sprays a cooling medium onto the photovoltaic module to cool the photovoltaic module according to the cooling strategy. The cooling target temperature is determined based on the current temperature of the second surface and the temperature rise data of the photovoltaic module, so that after the temperature of the photovoltaic module is lowered to the cooling target temperature, even if the temperature of the photovoltaic module rises due to the influence of the temperature rise data, the temperature after the temperature rise does not reach the set temperature, thereby avoiding the repeated work of cooling the photovoltaic module twice.

[0058] In another embodiment of the present application, a cooling strategy includes a cooling target temperature and a cleaning instruction, and a cooling instruction characterizing the cooling strategy is sent to the cooling robot so that the cooling robot cools the photovoltaic module according to the cooling strategy, including: sending a cooling instruction characterizing the cooling strategy to the cooling robot so that the cooling robot first cleans the second surface according to the cleaning instruction of the cooling strategy and then sprays a cooling medium on the second surface to cool it. Specifically, since the photovoltaic modules are deployed in open-air places, dust easily accumulates on the surface of the photovoltaic modules. When the cooling medium is sprayed on the photovoltaic modules, the dust will cause the cooling medium to be unable to spread evenly, thereby affecting the cooling effect on the photovoltaic modules. In this embodiment, the cooling robot first cleans the second surface according to the cleaning instruction and then sprays the cooling medium to ensure that the surface of the photovoltaic module is clean, so that the cooling medium can be evenly spread on the photovoltaic module, thereby improving the cooling effect on the photovoltaic module.

[0059] In the embodiments of the present application, the cooling target temperature may be 30°C to 40°C, for example, 30°C, 31°C, 32°C, 33°C, 34°C, 35°C, 36°C, 37°C, 38°C, 39°C, 40°C, etc., without limitation. Furthermore, the determined cooling strategy may include, in addition to the cooling target temperature, an estimated cooling time, which indicates the estimated time required to reduce the current temperature of the second surface to the cooling target temperature.

[0060] In an embodiment of the present application, during the process of spraying a cooling medium onto a photovoltaic module, the cooling control method 200 may further include: obtaining a cooling temperature of a cooling region on the second surface during cooling and the ambient temperature of the cooling region; comparing the difference between the cooling temperature and the ambient temperature with a set threshold; and, upon determining that the difference is greater than the set threshold, sending a temperature equalization instruction to a cooling robot, causing the cooling robot to perform a temperature equalization operation on the cooling region according to the temperature equalization instruction. It should be noted that when the difference between the cooling temperature of the cooling region and the ambient temperature of the cooling region is greater than the set threshold, the large temperature difference between the two makes the cooling region susceptible to cracking due to excessive cooling. In this embodiment, the cooling robot can monitor the cooling temperature of the cooling region during cooling and the ambient temperature of the cooling region. When the difference between the two is greater than the set threshold, a temperature equalization instruction is generated. The cooling robot can then perform a temperature equalization operation on the cooling region according to the temperature equalization instruction to prevent cracking in the cooling region.

[0061] In the embodiments of the present application, the cooling medium may include water or an organic liquid, or a mixture of water and an organic liquid, which is not limited thereto. The organic liquid may be alcohol, ethylene glycol, propylene glycol, etc., which is not limited thereto.

[0062] In an embodiment of the present application, the cooling robot can travel along a pre-set route to spray a cooling medium on the photovoltaic component, or first clean the second surface and then spray the cooling medium on the second surface for cooling.

[0063] In an embodiment of the present application, after cooling is complete, the cooling control method 200 may further include: obtaining the post-cooling temperature of the first surface and the post-cooling temperature of the second surface; and adjusting the set temperature based on the post-cooling temperature of the first surface and the post-cooling temperature of the second surface. The post-cooling temperature of the first surface may be collected by a temperature acquisition device; the post-cooling temperature of the second surface may be collected by a temperature acquisition device or by a cooling robot. The adjusted set temperature is used in the next cooling control process of the photovoltaic module.

[0064] Based on the above description, according to the cooling control method of the embodiment of the present application, the cooling instruction used to characterize the cooling strategy is determined according to the current temperature of the second surface and the temperature rise data of the photovoltaic component, and the cooling instruction is sent to the cooling robot. On the one hand, by cooling the photovoltaic component through the cooling robot, it can be ensured that all areas of the photovoltaic component can be cooled, and there will be no cooling dead corners. On the other hand, the cooling robot performs cooling according to the cooling strategy, which can effectively control the cooling effect.

[0065] The above exemplary describes the cooling control method according to the embodiment of the present application. Figure 3 Another aspect of the present application provides a temperature reduction control device. Figure 3 FIG. 3 shows a schematic block diagram of a temperature reduction control device 300 according to an embodiment of the present application. Figure 3 As shown, the cooling control device 300 according to an embodiment of the present application is applied to a photovoltaic module and may include a first surface temperature acquisition module 310, a second surface temperature acquisition module 320, a cooling strategy determination module 330, and a cooling instruction sending module 340. The first surface temperature acquisition module 310 is used to acquire the current temperature of the first surface of the photovoltaic module; the second surface temperature acquisition module 320 is used to determine whether the current temperature of the first surface is greater than a set temperature, and if it is determined that the current temperature is greater than the set temperature, acquire the current temperature of the second surface of the photovoltaic module; the cooling strategy determination module 330 is used to determine a cooling strategy based on the current temperature of the second surface and the temperature rise data of the photovoltaic module; the cooling strategy includes a cooling target temperature; and the cooling instruction sending module 340 is used to send a cooling instruction representing the cooling strategy to a cooling robot, so that the cooling robot cools the photovoltaic module according to the cooling strategy.

[0066] In an embodiment of the present application, a temperature acquisition device is used to acquire the current temperature of the first surface of a photovoltaic module. The first surface temperature acquisition module 310 then acquires the current temperature of the first surface acquired by the temperature acquisition device. The temperature acquisition device may be a thermocouple, thermal resistor, thermistor, or other temperature measuring element, without limitation. The first surface may be the back or front of a photovoltaic module, and correspondingly, the second surface may be the front or back of the photovoltaic module. For ease of description, the following description will be based on an example in which the first surface is the back of a photovoltaic module and the second surface is the front of the photovoltaic module.

[0067] In an embodiment of the present application, after obtaining the current temperature of the first surface, the second surface temperature acquisition module 320 compares the current temperature of the first surface with the set temperature to determine whether the current temperature of the first surface is greater than the set temperature. It should be noted that due to the sunlight irradiating the front of the photovoltaic module, there is a certain hysteresis in the temperature transfer from the first surface of the photovoltaic module to the second surface. Therefore, the current temperature of the first surface collected should be lower than the current temperature of the second surface. Therefore, when setting the set temperature in advance, the above hysteresis needs to be considered. For example, the set temperature is 50-55°C, for example, it can be selected as 50°C, 51°C, 52°C, 53°C, 54°C, 55°C, etc., and there is no limitation on this.

[0068] In an embodiment of the present application, after determining that the current temperature of the first surface is greater than the set temperature, the temperature-lowering control device 300 may further perform the following steps: sending a movement instruction to the temperature-lowering robot, so that the temperature-lowering robot moves to the location of the photovoltaic module after receiving the movement instruction. Specifically, when the current temperature of the first surface is greater than the set temperature, it indicates that the back surface temperature of the photovoltaic module is higher. Due to the hysteresis of temperature, the front surface temperature of the photovoltaic module should be even higher. Therefore, the temperature-lowering robot needs to be moved to the location of the photovoltaic module to prepare for cooling the photovoltaic module. The movement instruction to the temperature-lowering robot may be sent by wired or wireless means, and this is not limited to this.

[0069] In an embodiment of the present application, after determining that the current temperature of the first surface is greater than the set temperature, the temperature reduction control device 300 further obtains the current temperature of the second surface of the photovoltaic module. Specifically, the current temperature of the second surface of the photovoltaic module can be collected using a temperature acquisition device. The temperature acquisition device can be a temperature measuring element such as a thermocouple, thermal resistor, or thermistor, without limitation. Alternatively, the current temperature of the second surface of the photovoltaic module can be collected using a temperature reduction robot that moves to the location of the photovoltaic module.

[0070] In an embodiment of the present application, after obtaining the current temperature of the second surface, a cooling strategy is determined based on the current temperature of the second surface and the temperature rise data of the photovoltaic module. Specifically, after cooling the photovoltaic module, the temperature of the photovoltaic module will rise due to the influence of the temperature rise data of the photovoltaic module. In order to avoid the temperature after the rise being greater than the set temperature again and requiring a second cooling, when determining the cooling strategy, in addition to considering the current temperature of the second surface, the temperature rise data of the photovoltaic module can also be comprehensively considered. This makes it possible that after cooling the second surface, even if the temperature of the photovoltaic module subsequently rises, the temperature after the rise will not reach the set temperature, thus avoiding the duplication of the second cooling. The temperature rise data can include at least one of the following: light intensity, remaining light duration, and the temperature rise rate of the photovoltaic module. The temperature value of the photovoltaic module after cooling can be calculated based on the temperature rise data such as light intensity, remaining light duration, and the temperature rise rate of the photovoltaic module.

[0071] In an embodiment of the present application, a cooling strategy may include a cooling target temperature, and a cooling instruction representing the cooling strategy is sent to a cooling robot so that the cooling robot cools the photovoltaic module according to the cooling strategy, including: sending a cooling instruction representing the cooling strategy to the cooling robot so that the cooling robot sprays a cooling medium on the photovoltaic module according to the cooling strategy to cool the photovoltaic module. The cooling target temperature is determined based on the current temperature of the second surface and the temperature rise data of the photovoltaic module, so that after the temperature of the photovoltaic module is lowered to the cooling target temperature, even if the temperature of the photovoltaic module rises due to the influence of the temperature rise data, the temperature after the rise does not reach the set temperature, thereby avoiding the repeated work of cooling twice. The cooling target temperature may be 30-40°C, for example, 30°C, 31°C, 32°C, 33°C, 34°C, 35°C, 36°C, 37°C, 38°C, 39°C, 40°C, etc., without limitation. In addition, the determined cooling strategy may include not only the cooling target temperature but also an estimated cooling time, where the estimated cooling time represents the time estimated to be required to reduce the current temperature of the second surface to the cooling target temperature.

[0072] In another embodiment of the present application, a cooling strategy includes a cooling target temperature and a cleaning instruction, and a cooling instruction characterizing the cooling strategy is sent to the cooling robot so that the cooling robot cools the photovoltaic module according to the cooling strategy, including: sending a cooling instruction characterizing the cooling strategy to the cooling robot so that the cooling robot first cleans the second surface according to the cleaning instruction of the cooling strategy and then sprays a cooling medium on the second surface to cool it. Specifically, since the photovoltaic modules are deployed in open-air places, dust easily accumulates on the surface of the photovoltaic modules. When the cooling medium is sprayed on the photovoltaic modules, the dust will cause the cooling medium to be unable to spread evenly, thereby affecting the cooling effect on the photovoltaic modules. In this embodiment, the cooling robot first cleans the second surface according to the cleaning instruction and then sprays the cooling medium to ensure that the surface of the photovoltaic module is clean, so that the cooling medium can be evenly spread on the photovoltaic module, thereby improving the cooling effect on the photovoltaic module.

In this embodiment, the cooling robot can monitor the cooling temperature of the cooling area during cooling and the ambient temperature of the cooling area. When the difference between the two is greater than the set threshold, a temperature equalization instruction is generated. The cooling robot can then perform a temperature equalization operation on the cooling area according to the temperature equalization instruction to prevent cracking in the cooling area.

[0091] In one embodiment of the present application, when the computer program is executed by a computer or processor, the computer or processor performs the following steps: obtaining the current temperature of the first surface of the photovoltaic module; comparing the current temperature of the first surface with the set temperature, and obtaining the current temperature of the second surface of the photovoltaic module after determining that the current temperature of the first surface is greater than the set temperature; determining a cooling strategy based on the current temperature of the second surface and the temperature rise data of the photovoltaic module; and sending a cooling instruction for characterizing the cooling strategy to a cooling robot, so that the cooling robot cools the photovoltaic module according to the cooling strategy.

[0092] In one embodiment of the present application, after determining that the current temperature of the first surface is greater than the set temperature, the computer program, when executed by the computer or processor, enables the computer or processor to further perform the following steps: sending a movement instruction to the cooling robot so that the cooling robot moves to the location of the photovoltaic component after receiving the movement instruction.

[0093] In one embodiment of the present application, the cooling strategy includes a cooling target temperature, and a cooling instruction for characterizing the cooling strategy is sent to the cooling robot so that the cooling robot cools the photovoltaic component according to the cooling strategy, including: sending a cooling instruction for characterizing the cooling strategy to the cooling robot so that the cooling robot sprays a cooling medium on the photovoltaic component for cooling according to the cooling strategy.

[0097] In one embodiment of the present application, the cooling strategy further includes an estimated cooling time, where the estimated cooling time represents the time estimated to be required to reduce the current temperature of the second surface to the cooling target temperature.

[0098] In one embodiment of the present application, the temperature rise data includes at least one of the following: light intensity, remaining light duration, and temperature rise speed of the photovoltaic component.

[0099] In one embodiment of the present application, the set temperature is 50-55°C.

[0100] In one embodiment of the present application, the cooling target temperature is 30-40°C.

[0101] In addition, according to an embodiment of the present application, a cooling robot is also provided. Figure 5 FIG. 5 shows a schematic block diagram of a cooling robot 500 according to an embodiment of the present application. Figure 5 As shown, a cooling robot 500 according to an embodiment of the present application includes a temperature detection module 530, a communication module 510, and a cooling module 550. The temperature detection module 530 is configured to collect the current temperature of the second surface of the photovoltaic module; the communication module 510 is configured to transmit the current temperature of the second surface to a cooling control device and to receive a cooling instruction from the cooling control device that indicates a cooling strategy; and the cooling module 550 is configured to cool the photovoltaic module according to the cooling strategy.

[0102] In the embodiment of the present application, the temperature detection module 530 can be selected as a temperature measuring element such as a thermocouple, a thermal resistor, or a thermistor, which is not limited.

[0103] In an embodiment of the present application, the communication module 510 is also used to receive movement instructions sent by the temperature-cooling control device; the temperature-cooling robot 500 also includes a movement module 520, and the movement module 520 is used to move the temperature-cooling robot to the location of the photovoltaic module according to the movement instruction. Specifically, when the temperature-cooling control device detects that the current temperature of the first surface is greater than the set temperature, it indicates that the temperature on the back of the photovoltaic module is higher. Due to the hysteresis of the temperature, the temperature on the front of the photovoltaic module should be higher. Therefore, the temperature-cooling robot 500 needs to be transferred to the location of the photovoltaic module to prepare for cooling the photovoltaic module. Among them, when the communication module 510 receives the movement instruction, it can adopt a wired or wireless method, which is not limited. When the communication module 510 adopts a wireless method to receive the movement instruction, the communication module 510 can be a wireless network module.

[0104] In an embodiment of the present application, a cooling strategy includes a cooling target temperature, and cooling the photovoltaic module according to the cooling strategy includes spraying a cooling medium onto the photovoltaic module according to the cooling strategy to cool the photovoltaic module. The cooling target temperature is determined based on the current temperature of the second surface and the temperature rise data of the photovoltaic module. This ensures that after the temperature of the photovoltaic module is lowered to the cooling target temperature, even if the temperature of the photovoltaic module rises due to the influence of the temperature rise data, the temperature after the temperature rise does not reach the set temperature, thereby avoiding the repeated work of cooling the photovoltaic module twice.

[0105] In an embodiment of the present application, the cooling strategy includes a cooling target temperature and a cleaning instruction; the cooling robot 500 also includes a cleaning module 540, and the cleaning module 540 first performs a cleaning operation on the second surface according to the cleaning strategy before the cooling module 550 sprays the cooling medium onto the second surface. Specifically, since the photovoltaic modules are deployed in open-air places, dust easily accumulates on the surface of the photovoltaic modules. When the cooling medium is sprayed onto the photovoltaic modules, the dust will cause the cooling medium to be unable to be evenly spread, thereby affecting the cooling effect on the photovoltaic modules. In this embodiment, before the cooling robot 500 sprays the cooling medium onto the second surface, the cleaning module 540 first performs a cleaning operation on the second surface according to the cleaning instruction to ensure that the surface of the photovoltaic modules is clean, so that the cooling medium can be evenly spread on the photovoltaic modules, thereby improving the cooling effect on the photovoltaic modules.

[0106] In the embodiments of the present application, the cooling strategy further comprises an estimated cooling time, which represents a time required for reducing the current temperature of the second surface to the cooling target temperature. The cooling robot 500 determines a length of time for spraying the cooling medium to the photovoltaic module according to the estimated cooling time, so as to reduce the temperature of the photovoltaic module to the cooling target temperature. The cooling target temperature can be 30-40℃, for example, 30℃, 31℃, 32℃, 33℃, 34℃, 35℃, 36℃, 37℃, 38℃, 39℃, 40℃, etc., which are not limited.

[0107] In the embodiments of the present application, the temperature detection module 530 is further configured to collect the temperature at the cooling time of the cooling area in the second surface and the ambient temperature of the cooling area. The communication module 510 is further configured to send the temperature at the cooling time and the ambient temperature to the cooling control device, so that the cooling control device compares the difference between the temperature at the cooling time and the ambient temperature with a set threshold value, and sends a temperature equalization instruction to the cooling robot 500 when it is determined that the difference is greater than the set threshold value. As shown in Figure 5 The cooling robot 500 further comprises a temperature equalization member 560, which is configured to perform a temperature equalization operation on the cooling area according to the temperature equalization instruction. It should be noted that when the difference between the temperature at the cooling time of the cooling area and the ambient temperature of the cooling area is greater than the set threshold value, the cooling area at this position is prone to cracking due to rapid cooling. In the present embodiment, the temperature at the cooling time of the cooling area and the ambient temperature of the cooling area can be monitored by the cooling robot 500. When the difference between the two is greater than the set threshold value, the cooling control device generates a temperature equalization instruction, and the temperature equalization member 560 can perform a temperature equalization operation on the cooling area at this position according to the temperature equalization instruction, so as to prevent the cooling area at this position from cracking. The temperature equalization member 560 can be a temperature equalization plate or other equipment, which is not limited.

[0108] In the embodiments of the present application, the cooling medium can comprise water or an organic liquid, or a mixture of water and an organic liquid, which is not limited. The organic liquid can be alcohol, ethylene glycol, propylene glycol, etc., which is also not limited.

[0109] In the embodiments of the present application, the cooling robot 500 can travel along a pre-set route to spray the cooling medium to the photovoltaic module, or first clean the second surface and then spray the cooling medium to the second surface for cooling.

[0110] According to another aspect of the present application, a cooling system is also provided. The following refers to Figure 6 The cooling system of the present application is explained and described. Among them, Figure 6 The structure of the cooling system for the photovoltaic module 700 according to an embodiment of the present application is shown. The technical features in the various embodiments of the present application can be combined with each other without conflict.

[0111] In one embodiment of the present application, Figure 6 As shown, a cooling system is applied to a photovoltaic module 700 and may include a temperature sensor 610, a cooling robot 620, and a cooling control device 630. The temperature sensor 610, the cooling robot 620, and the cooling control device 630 are communicatively connected. The communication connection may be a wired connection or a wireless connection, which is not limited thereto.

[0112] In the embodiment of the present application, a temperature sensor 610 may be disposed on the first surface of a photovoltaic module 700 and is used to collect the temperature of the first surface of the photovoltaic module 700, including temperature data such as the current temperature and the temperature after cooling. The temperature sensor 610 may be a thermocouple, an RTD (resistance temperature detector), a thermistor, or a semiconductor-based integrated circuit (IC), without limitation.

[0113] In an embodiment of the present application, the cooling robot 620 can be implemented as the cooling robot 500 described above, and the cooling control device 630 can be implemented as the cooling control devices 300 and 400 described above. Please refer to the description above and will not repeat them here.

[0114] Based on the cooling system, temperature sensor 610 can continuously collect the current temperature of the first surface of photovoltaic module 700 and transmit this current temperature to cooling control device 630. After obtaining the current temperature of the first surface, cooling control device 630 compares it with a set temperature. If the current temperature of the first surface is greater than the set temperature, cooling control device 630 sends a movement instruction to cooling robot 620. The movement module of cooling robot 620 drives cooling robot 620 to the location of photovoltaic module 700 according to the movement instruction. Then, the temperature detection module of cooling robot 620 can collect the current temperature of the second surface of photovoltaic module 700 and transmit this current temperature to cooling control device 630 via the communication module. Based on the current temperature of the second surface and the temperature rise data of photovoltaic module 700, cooling control device 630 determines a cooling strategy and sends a cooling instruction indicating the cooling strategy to cooling robot 620. After receiving the cooling command, the mobile module drives the cooling robot 620 along a set route. During the route, the cooling robot 620 first cleans the second surface of the photovoltaic module 700 using the cleaning module. Then, the cooling module of the cooling robot 620 sprays a cooling medium onto the photovoltaic module 700 according to the cooling strategy to reduce the temperature of the photovoltaic module 700 to the target temperature. During the cooling process, the temperature detection module of the cooling robot 620 can also collect the cooling temperature of the cooling area on the second surface and the ambient temperature of the cooling area, and transmit these to the cooling control device 630 via the communication module. The cooling control device 630 compares the difference between the cooling temperature and the ambient temperature with a set threshold value. If the difference is greater than the set threshold value, it sends a temperature equalization command to the cooling robot 620. The temperature equalization component of the cooling robot 620 performs a temperature equalization operation on the cooling area according to the temperature equalization command to prevent cracking in the cooling area. After the cooling is completed, the temperature detection module of the cooling robot 620 collects the cooled temperature of the second surface of the photovoltaic component 700 and transmits it to the cooling control device 630. The temperature sensor 610 collects the cooled temperature of the first surface of the photovoltaic component 700 and transmits it to the cooling control device 630. The cooling control device 630 adjusts the set temperature according to the cooled temperature of the first surface and the cooled temperature of the second surface. The adjusted set temperature is used for the next cooling control process of the photovoltaic component 700.
