[0039] Currently, air conditioner outdoor units typically have a photovoltaic control box. This box collects solar energy to reduce the power consumption of the compressor during operation, thus saving electricity. However, the photovoltaic control box contains inductive components with high heat output, which can cause the air temperature inside the box to rise, thereby affecting its performance.

[0040] Therefore, as Figure 1 and Figure 2 As shown, this utility model proposes a photovoltaic control box, aiming to improve the working performance of the photovoltaic control box. In one embodiment, the photovoltaic control box includes a housing, an electronic control board, and an inductor. The electronic control board and the inductor are located at different positions in the housing and can be set at a certain distance apart, which avoids the inductor overheating and affecting the performance of the electronic control board, and at the same time improves the working performance of the photovoltaic control box.

[0041] In this embodiment, as Figure 1As shown, the housing 100 has a first side when it is installed on the target device. The housing 100 has a first receiving cavity 111 located near the first side and a second receiving cavity 112 located away from the first side. It can be understood that, optionally, the target device can be an air conditioner outdoor unit, and the housing 100 is located at the top of the casing 400 of the air conditioner outdoor unit. Thus, the first side of the housing 100 is close to or conforms to the top of the air conditioner outdoor unit, that is, the first side is the side corresponding to the contact surface between the housing 100 and the top of the air conditioner outdoor unit. The first receiving cavity 111 is located relatively close to the top of the air conditioner outdoor unit, while the second receiving cavity 112 is located relatively away from the top of the air conditioner outdoor unit, that is, the second receiving cavity 112 extends towards the interior of the air conditioner outdoor unit. In this way, two relatively spaced cavities can be effectively formed, which facilitates subsequent heat insulation treatment. It should be noted that, based on the above structure, two spaced installation spaces are distinguished, which can be used to install the control board 200 and the inductor 300 respectively. This effectively avoids the heat generated by the inductor 300 from affecting the operation of the control board 200, thus effectively increasing the working performance of the photovoltaic control box 10.

[0042] In this embodiment, the control board 200 is disposed in the first receiving cavity 111; the inductor 300 is disposed in the second receiving cavity 112 away from the control board 200, and the inductor 300 is electrically connected to the control board 200 through a conductive element. Optionally, the space of the first receiving cavity 111 can be larger than that of the second receiving cavity 112. That is, the first receiving cavity 111 is the main space of the housing 100 of the photovoltaic control box 10, used to install most of the devices, while the second receiving cavity 112 is an extension space of the housing 100 of the photovoltaic control box 10, used to separately install the inductor 300, so as to effectively isolate the inductor 300 and the control board 200. In this way, by separately disposing of the inductor 300 in the second receiving cavity 112, the heat emitted by the inductor 300 can be prevented from affecting the interior of the photovoltaic control box 10, preventing the temperature of the photovoltaic control box 10 from rising, thereby giving the photovoltaic control box 10 higher operating performance.

[0043] In this embodiment, the control board 200 is disposed in the first receiving cavity 111. The circuit board has a first side surface and a second side surface that are disposed opposite to each other. The first side surface of the circuit board is disposed near the contact surface of the housing 100. The electronic components are disposed on the second side surface of the circuit board. The inductor 300 is disposed in the second receiving cavity 112 at a position away from the control board 200, which can effectively separate the control board 200 and the inductor 300, and prevent the heat emitted by the inductor 300 from affecting the entire photovoltaic control box 10.

[0044] Optionally, the enclosure 100 can be a cuboid, a cylinder, or a trapezoid; the specific shape is not limited here. In addition, the enclosure 100 can be made of metal, insulating material, or both, with the metal material encased within the insulating material. The enclosure 100 can also be made of weather-resistant material to increase the waterproof and dustproof capabilities of the photovoltaic control box 10.

[0045] It should be explained that the photovoltaic control box 10 is located at the top and side of the housing 400, which differs from its location at the bottom. When the photovoltaic control box 10 is installed at the top and side of the air conditioner outdoor unit, the circuit board faces downwards (i.e., the electronic components face downwards). Due to gravity, most dust and moisture will fall downwards, thus preventing pollutants such as dust and rainwater from directly settling on the circuit board and its electronic components, thereby avoiding dust accumulation. However, when located at the bottom, the circuit board faces upwards, leading to dust accumulation. But this only addresses the issue of dust accumulation. Regarding space saving, regardless of its location on the target device, it contributes to the miniaturization of the device.

[0046] In some exemplary photovoltaic (PV) control boxes, the PV control box is located behind the target device, while the inductor is mounted on a circuit board and housed within the PV control box's cavity. This means the exemplary PV control box has only a single chamber, failing to adequately address the heat generated by the inductor, resulting in poor heat dissipation. This could shorten the lifespan of electronic components and increase the failure rate. Furthermore, in high-temperature environments, excessively high internal temperatures of the PV control box may trigger protection mechanisms, restricting the normal operation of the air conditioning system and thus impacting the user experience.

[0047] In summary, this utility model proposes a photovoltaic control box 10, in which the control board 200 is disposed in the first receiving cavity 111 of the box 100 and the inductor 300 is disposed in the second receiving cavity 112 of the box 100. By separating the control board 200 and the inductor 300 in different receiving cavities, it is possible not only to effectively reduce the impact of the inductor 300 on the control board 200 and reduce interference caused by heat conduction and heat radiation, but also to help build a more stable working environment, thereby enhancing the working performance of the photovoltaic control box 10.

[0048] In one embodiment, such as Figure 2As shown, the housing 100 includes a first housing 121 and a second housing 122. The first housing 121 has a first receiving cavity 111, and the second housing 122 has a second receiving cavity 112. It can be understood that the housing 100 of the photovoltaic control box 10 can be composed of two independent parts: the first housing 121 and the second housing 122. The first housing 121 includes the first receiving cavity 111 for housing the electronic control board 200 and its related electronic components; while the second housing 122 includes the second receiving cavity 112 for installing the inductor 300, which generates significant heat. This design helps to isolate the heat source from the sensitive electronic components, thereby reducing the impact of heat on the performance of the electronic control board 200 and improving the overall performance of the photovoltaic control box 10.

[0049] On the other hand, the structure of this photovoltaic control box 10 is conducive to heat dissipation, effectively dissipating the heat emitted by the inductor 300, thereby enhancing the heat dissipation performance of the photovoltaic control box 10. It is worth noting that the photovoltaic control box 10 is equipped with a photovoltaic control (MPPT) module, which can automatically adjust the operating point under different light and temperature conditions to ensure that the photovoltaic system always operates in optimal condition, thereby maximizing energy output. Therefore, with its enhanced heat dissipation performance, the MPPT module of the photovoltaic control box 10 can achieve even better performance.

[0050] Optionally, the connection between the first enclosure 121 and the second enclosure 122 can be achieved using a fastener 150, which can be a screw, clip, or any other suitable mechanical connection method, ensuring a stable connection between the two parts while allowing necessary disassembly and maintenance. Understandably, the advantage of connecting via the fastener 150 is that it provides greater flexibility to the enclosure 100, allowing for easy maintenance or replacement of specific components when needed, without having to replace the entire photovoltaic control box 10. Furthermore, this modular design facilitates quality control during production and assembly, as each enclosure 100 can be individually tested for functional integrity before assembly.

[0051] Optionally, the first housing 121 and the second housing 122 are integrally formed and connected, for example, through mold casting or injection molding processes, to ensure a seamless and durable connection. This integral connection not only enhances the overall structural integrity but also reduces problems caused by loose connections, while simplifying the manufacturing process and lowering production costs. For air conditioner outdoor units that need to be exposed to the outdoor environment for extended periods, the integral housing 100 also provides better waterproof and dustproof performance, further improving the reliability and service life of the photovoltaic control box 10.

[0052] It should be noted that the specific connection form of the first enclosure 121 and the second enclosure 122 is not limited here. The key is that the first enclosure 121 and the second enclosure 122 respectively house the electronic control board 200 and the inductor 300, which can better dissipate heat.

[0053] In one embodiment, such as Figure 2 As shown, the photovoltaic control box 10 also includes a heat insulation component 130, which is sandwiched between the first housing 121 and the second housing 122. It can be understood that providing the heat insulation component 130 at the connection between the first housing 121 and the second housing 122 can further enhance the thermal isolation effect between the two housing cavities, ensuring that the heat generated by the inductor 300 does not significantly affect the working environment of the control board 200. The heat insulation component 130 helps maintain the control board 200 operating at a suitable working temperature and can also improve the overall performance of the photovoltaic control box 10 and extend its service life.

[0054] Optionally, the heat insulation component 130 can be a heat insulation sponge, achieving effective heat insulation while ensuring the photovoltaic control box 10 is lightweight and its design is simplified. It should be noted that the specific material of the heat insulation component 130 is not limited here, and the specific material of the heat insulation component 130 can be determined according to the actual application requirements.

[0055] In this embodiment, the heat insulation component 130 has a connection hole through which the control board 200 and the inductor 300 are electrically connected. It is understood that the connection hole is used to achieve the electrical connection between the control board 200 and the inductor 300, ensuring smooth and unobstructed current transmission. The position and number of connection holes are optimized according to actual circuit requirements to ensure good electrical performance while minimizing heat transfer. Balancing the needs of electrical connection with the requirements of thermal management according to actual application needs can improve the working efficiency of the photovoltaic control box 10.

[0056] In one embodiment, such as Figure 2 As shown, the photovoltaic control box 10 also includes a heat sink 140, which is disposed within the second housing 122 and encloses the inductor 300. It is understood that the heat sink 140, located within the second housing 122 and directly enclosing the inductor 300, ensures that heat can be rapidly conducted from the inductor 300 to the heat sink 140, and then dissipated through the heat sink 140. This helps maintain the inductor 300 within a suitable operating temperature range, thereby ensuring stable performance and extending its service life.

[0057] Optionally, the second enclosure 122 is made of sheet metal, which can effectively dissipate heat.

[0058] Optionally, the heat sink 140 can be made of a material with high thermal conductivity, enabling it to quickly conduct heat away from the inductor 300. It is important to note that the heat sink 140 needs to be an insulating material to prevent the inductor 300 from being affected by electrical components. Furthermore, the surface of the heat sink 140 can undergo special treatment or design, such as adding fin structures, employing microchannel technology, or coating with a high emissivity coating. In this embodiment, the heat sink 140 is a potting compound, which better fits the shape of the second receiving cavity 112 of the second housing 122 and can securely position the inductor 300 in the corresponding location, thus achieving effective heat dissipation.

[0059] In practical applications, the heat sink 140 can also be combined with an external cooling system, such as a natural air cooling system or a forced air cooling system. For example, when the photovoltaic control box 10 is installed in the target device, such as an air conditioner outdoor unit, the second enclosure 122 can be installed in the air duct 410 of the air conditioner outdoor unit. By accelerating airflow through natural ventilation or forced ventilation by the fan 600, the heat on the heat sink 140 can be removed, achieving more efficient heat dissipation.

[0060] In one embodiment, such as Figure 2 As shown, the enclosure 100 includes a first enclosure 121 and a second enclosure 122. The first enclosure 121 includes a first insulating enclosure 1211 and a first protective enclosure 1212. The first insulating enclosure 1211 is disposed within the first protective enclosure 1212, and the second enclosure 122 includes a second protective enclosure 1221. It is understood that the first enclosure 121 contains a first insulating enclosure 1211 for housing the control board 200 and its related sensitive electronic components. The main function of the first insulating enclosure 1211 is to provide electrical isolation, prevent external electromagnetic interference (EMI) from affecting the internal circuitry, and protect these components from environmental factors such as moisture and dust. The first insulating enclosure 1211 is housed within a larger first protective enclosure 1212. The first protective enclosure 1212 not only provides physical protection for the internal insulating enclosure 100 against external impacts and vibrations, but may also have waterproof and dustproof functions, ensuring that the entire photovoltaic control box 10 can operate stably in harsh environments.

[0061] In one example, the material of the first insulating box 1211 can be plastic, and the materials of the first protective box 1212 and the second protective box 1221 can be sheet metal; there is no specific limitation, the key is their insulating and protective functions.

[0062] Optionally, the first protective enclosure 1212 and the second protective enclosure 1221 are fixedly connected by fasteners 150. It is understood that using fasteners 150, such as screws, bolts, or clips, not only ensures a secure connection between the two enclosures 100 but also allows for easy disassembly and reassembly when needed. This is particularly suitable for applications that may require regular maintenance or repair, such as the photovoltaic control box 10 for an air conditioner outdoor unit.

[0063] Optionally, the first protective enclosure 1212 and the second protective enclosure 1221 are integrally formed and connected. It is understood that this integral forming can be achieved through mold casting or injection molding processes, ensuring a seamless and durable connection. This integral connection not only enhances the overall structural integrity and reduces problems caused by loose connections, but also simplifies the manufacturing process and reduces production costs. For air conditioner outdoor units that are exposed to outdoor environments for extended periods, the integrally formed enclosure 100 provides better waterproof and dustproof performance, further improving the reliability and service life of the photovoltaic control box 10.

[0064] In this embodiment, the first insulating housing 1211 has a connection hole corresponding to the position of the second protective housing 1221, and the control board 200 and the inductor 300 are electrically connected through the connection hole. This ensures unimpeded current transmission while minimizing heat transfer, ensuring the control board 200 operates within a suitable temperature range. The number and size of the connection holes can be adapted to the actual cables, providing effective thermal insulation while maintaining electrical connection.

[0065] In one embodiment, such as Figure 1 and Figure 2 As shown, the first protective housing 1212 has a recessed mounting groove 160, and the second protective housing 1221 is disposed in the mounting groove 160. The size of the mounting groove 160 is larger than that of the second protective housing 1221. It is understood that the first protective housing 1212 is designed with a recessed mounting groove 160, the size of which is larger than that of the second protective housing 1221, allowing the second protective housing 1221 to be embedded within it. This stepped design not only provides a stable mounting position for the second protective housing 1221 but also effectively reduces the risk of water entering the photovoltaic control box 10. Specifically, if water attempts to enter the photovoltaic control box 10, it needs to pass through the edge of the mounting groove 160 and then follow an additional curved path to reach the internal components, greatly reducing the possibility of direct water ingress. Furthermore, this design ensures that even in extreme cases of water ingress, the inductor 300 will not become the lowest point of the entire box, avoiding the formation of puddles.

[0066] like Figure 3 and Figure 4 As shown, this utility model also proposes a refrigeration device 20, which includes a housing 400, a device body 500, and a photovoltaic control box 10. The specific structure of the photovoltaic control box 10 is as described in the above embodiments. Since this refrigeration device 20 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0067] Understandably, since the cooling device 20 includes the photovoltaic control box 10, and the photovoltaic control box 10 can achieve high operating efficiency, the cooling device 20 also has higher operating performance. Optionally, the cooling device 20 can be a photovoltaic air conditioner; when the cooling device 20 is an air conditioner, it can specifically be an outdoor unit of an air conditioner; the photovoltaic control box 10 can specifically be a photovoltaic control box used to convert light energy into electrical energy. The outdoor unit of the air conditioner is located outdoors, while the photovoltaic control box is located within the outdoor unit, effectively collecting light energy.

[0068] It should be noted that when the refrigeration equipment 20 is an air conditioner, it can be a central air conditioner, a floor-standing air conditioner, a wall-mounted air conditioner, etc. However, the specific refrigeration equipment 20 is not limited here. The key point is that when the photovoltaic control box 10 is installed on the refrigeration equipment 20, it can help improve the working performance of the refrigeration equipment 20.

[0069] In one embodiment, the refrigeration device 20 includes a housing 400 and a device body 500 and a photovoltaic control box 10 disposed within the housing 400. In this embodiment, the housing 400 is located at a target position, and the first side of the housing 400 of the photovoltaic control box 10 is located at the top of the housing 400.

[0070] Understandably, the housing 400, as the outer shell of the entire refrigeration equipment 20, not only provides physical protection for the internal components but also serves an aesthetic and protective function. In this embodiment, the housing 400 is positioned at a target location, such as mounted on an exterior wall or a dedicated bracket. Specifically, the first side (i.e., the first protective housing 1212) of the photovoltaic control box 10 is located at the top of the housing 400. This allows the top of the housing 400 to fully utilize natural convection, making it easier for heat to dissipate. Simultaneously, it avoids the problem of dust accumulation at the bottom, reducing the impact of dust and moisture on the circuit board and its electronic components, and improving the operational stability and lifespan of the photovoltaic control box 10. More importantly, the entire photovoltaic control box 10 is in an inverted state, allowing its second receiving cavity 112 to be positioned relatively close to the interior of the housing 400, within the air duct 410. The airflow within the air duct 410 enhances heat dissipation, further improving operational performance.

[0071] In one embodiment, such as Figure 3 As shown, the housing 400 is also provided with an air inlet and an air outlet communicating with the air inlet. An air duct 410 is formed between the air inlet and the air outlet. The housing 100 of the photovoltaic control box 10 is located within the air duct 410, corresponding to the position of the second receiving cavity 112. In this way, the airflow path is fully utilized to optimize the heat dissipation performance of the inductor 300. By guiding the cooling air directly through the heat-generating components, it is ensured that heat can be quickly removed, thereby maintaining the stable operation of the inductor 300 within a suitable operating temperature range.

[0072] In one embodiment, such as Figure 3 and Figure 4 As shown, the cooling device 20 also includes a fan 600 disposed in the air duct 410, and the position of the housing 100 corresponding to the second receiving cavity 112 is arranged to avoid the rotation plane of the fan 600. It can be understood that, in order to ensure that the fan 600 can rotate freely without obstruction, the position of the housing 100 of the photovoltaic control box 10 corresponding to the second receiving cavity 112 is deliberately arranged to avoid the rotation plane of the fan 600. This not only prevents physical interference between the fan 600 and the photovoltaic control box 10, but also ensures that airflow can smoothly pass through the air duct 410 to directly cool the inductor 300. The forced airflow generated by the fan 600 significantly enhances the heat dissipation effect, enabling the inductor 300 to operate under more stable temperature conditions, thereby improving the overall performance of the cooling device 20.

[0073] In one embodiment, such as Figure 3 and Figure 4 As shown, the housing 100 also has a blade avoidance area 190 on the side near the fan 600, and the fan 600 operates within the blade avoidance area 190. It is understood that the purpose of the blade avoidance area 190 is to provide sufficient space for the fan 600, preventing it from colliding or rubbing against the photovoltaic control box 10 during high-speed rotation, while also ensuring smooth airflow. By precisely adjusting the relative position between the fan 600 and the photovoltaic control box 10, the airflow path can be optimized, allowing cooling air to more evenly cover the surface of the inductor element 300, further improving heat dissipation efficiency. Furthermore, the presence of the blade avoidance area 190 also helps reduce noise and vibration, providing a quieter and more stable operating environment, thus improving the user experience.

[0074] In one embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, the housing 100, corresponding to the first receiving cavity 111 and near the second receiving cavity 112, also includes an opening 170. The electronic control board 200 also includes a heat sink 180, which is disposed in the opening 170 so that the heat sink 180 is exposed outside the housing 100. The heat sink 180 is at least partially disposed in the air duct 410, and the heat sink 180 is arranged away from the rotation plane of the fan 600. It is worth noting that the arrangement of the heat sink 180 also avoids the rotation plane of the fan 600 to ensure that it will not affect the normal operation of the fan 600. In this way, the heat sink 180 can be directly exposed to the forced airflow, which greatly improves its heat dissipation efficiency and thus increases the working performance of the cooling device 20.

[0075] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
