Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of energy storage converters, and more specifically, to a heat dissipation device for energy storage converters. Background Art

[0002] Energy storage converters are one of the key devices in modern power systems and are widely used in solar power generation, wind power generation, and grid peak regulation. These devices generate a lot of heat during operation. If the heat is not dissipated in a timely and effective manner, the equipment will overheat or even be damaged, thus affecting the stability and safety of the system. Therefore, efficient heat dissipation devices are essential to ensure the normal operation of energy storage converters.

[0003] At present, in order to achieve effective heat dissipation of energy storage inverters, common methods include natural convection heat dissipation, forced ventilation heat dissipation and liquid cooling. Natural convection heat dissipation removes heat through the natural flow of air and is suitable for occasions with low heat generation; forced ventilation heat dissipation uses fans or other exhaust equipment to accelerate air circulation and improve heat dissipation efficiency, which is suitable for scenes with high heat generation; liquid cooling transfers heat to the external environment through circulating liquid, which is usually used in applications with high power density. In addition, some designs will combine multiple means, such as setting up multiple layers of heat sinks in the box or using semiconductor refrigeration sheets to enhance the heat dissipation effect.

[0004] However, existing heat sinks for energy storage converters have certain limitations, especially when used in complex environments. For example, in a humid or dusty environment, dust can easily enter the heat sink, causing a decrease in heat dissipation performance or even causing failures. At the same time, traditional heat sinks often lack effective rain protection measures, and rainwater intrusion may cause problems such as circuit short circuits. These problems limit the reliability and durability of existing heat sinks in actual application scenarios. Summary of the invention

[0047] Example 1

[0048] like Figure 1-Figure 3 As shown, an embodiment of the present application provides a heat dissipation device for an energy storage converter, including a housing 1, an air duct, a cooling mechanism, a dust removal mechanism, and an exhaust mechanism. Among them, an air inlet and an air outlet are relatively arranged on the housing 1, the air duct is arranged in the housing 1, and one end of the opening is connected to the air inlet, the cooling mechanism is arranged in the housing 1 and connected to the air duct, the dust removal mechanism is detachably arranged at the air inlet, and the exhaust mechanism is detachably arranged at the air outlet. This design can effectively prevent dust and rainwater from entering the interior of the housing 1, improve the heat dissipation efficiency, and enhance the reliability of the equipment.

[0049] Specifically, the air duct includes an air inlet connector 2 and an air duct 3. The air inlet connector 2 is arranged at the air inlet, the air duct 3 is detachably connected to the air inlet connector 2, and the cooling mechanism is connected to the air duct 3. This makes it easy to maintain and replace components, and also improves the flexibility of the overall device.

[0050] More specifically, the upper end of the air duct 3 is in contact with the inner wall of the box 1, the cooling mechanism passes through the box 1, and its heat absorbing end passes through the air duct 3 and extends into the air duct 3. This design allows the cooling medium to directly contact the part that needs to dissipate heat, thereby improving the heat transfer efficiency.

[0051] The cooling mechanism further includes a first positioning frame 4, a semiconductor cooling sheet 5, an inner heat dissipation fin 6 and an outer heat dissipation fin 7. A mounting opening is provided at the upper end of the housing 1, the first positioning frame 4 is embedded in the mounting opening, and a notch communicating with the mounting opening is provided at the upper end of the air duct 3. The semiconductor cooling sheet 5 is embedded in the first positioning frame 4, the inner heat dissipation fin 6 is arranged in the air duct 3 and connected to one side of the semiconductor cooling sheet 5, and the outer heat dissipation fin 7 is arranged on the housing 1 and connected to the other side of the semiconductor cooling sheet 5. In this way, the heat exchange between the inside and outside is more efficient, and the heat dissipation effect is improved.

[0052] In order to further enhance the rainproof capability, a rain cover 16 is provided at the upper end of the box body 1, and the outer heat dissipation fins 7 are located inside the rain cover 16. The rain cover 16 includes an inner cover body 8 and an outer cover body 10. The inner cover body 8 is provided at the upper end of the box body 1 and wraps the outer heat dissipation fins 7. A plurality of heat dissipation holes are provided at intervals at the upper end of the inner cover body 8. The connecting shaft 9 is vertically provided at the upper end of the inner cover body 8. The outer cover body 10 is provided outside the inner cover body 8 and is detachably connected to the connecting shaft 9. There is a gap between the outer cover body 10 and the upper end of the box body 1. This design not only effectively blocks rainwater, but also ensures a good ventilation effect.

[0053] The dust removal mechanism includes a connection frame 11, a waterproof shell 12, a filter 13 and a louver 14. The connection frame 11 is arranged at the air inlet, and the waterproof shell 12 is detachably connected to the connection frame 11. The waterproof shell 12 has an L-shaped air guide groove, one side of the air guide groove is opened to communicate with the air inlet, and the other side of the air guide groove is opened downward, and the filter 13 is embedded in the opening of one side of the waterproof shell 12. The louver 14 is arranged at the opening of the other side of the waterproof shell 12. This design can not only effectively filter out most of the dust, but also prevent rainwater from entering the interior of the box body 1.

[0054] The exhaust mechanism includes a second positioning frame 15, a rain cover 16 and a fan 17. The second positioning frame 15 is arranged at the air outlet, the rain cover 16 is L-shaped, one side opening of the rain cover 16 is detachably connected to the second positioning frame 15, and the other side opening faces downward, and the fan 17 is embedded in the one side opening of the rain cover 16. This design can prevent external moisture from entering the interior of the box body 1 while discharging heat.

[0055] The temperature sensor is arranged in the box 1 to obtain the temperature in the box 1. By monitoring the temperature in real time, the operation state of the cooling system can be better controlled to ensure the safe and stable operation of the equipment.

[0056] The implementation principle of this embodiment is: through a multi-level design, effective heat dissipation of the energy storage converter is achieved, and at the same time, it has strong dust and rain resistance. This design not only improves the heat dissipation efficiency, but also significantly improves the reliability and durability of the equipment, and is particularly suitable for applications in complex environments.

[0057] Example 2

[0058] The difference between this embodiment and the above embodiment is that an intelligent temperature control module is added, which can automatically adjust the heat dissipation intensity according to actual needs. Specifically, the data collected by the temperature sensor is transmitted to the controller, and the controller controls the speed of the fan 17 and the operating frequency of the semiconductor cooling plate 5 according to the preset temperature threshold, thereby achieving precise temperature control.

[0059] Specifically, the intelligent temperature control module includes a microprocessor, a power management unit, and a communication interface. The microprocessor receives data from the temperature sensor and calculates the appropriate heat dissipation strategy based on the built-in algorithm. The power management unit is responsible for powering each component to ensure the stable operation of the system. The communication interface is used to exchange data with other devices for remote monitoring and management.

[0060] In addition, in order to improve the adaptability of the system, a humidity sensor can be added to detect the humidity inside the box 1. If the humidity exceeds the set value, the dehumidification function can be started to avoid electrical failures caused by excessive humidity.

[0061] The implementation principle of this embodiment is: by introducing an intelligent temperature control module, precise control of the heat dissipation system of the energy storage converter is achieved, greatly improving the intelligence level of the system. This design can not only maintain a stable heat dissipation effect in various environments, but also effectively extend the service life of the equipment and reduce maintenance costs.

[0062] Example 3

[0063] The difference between this embodiment and the above embodiment is that liquid cooling technology is used as an auxiliary heat dissipation method. Specifically, a liquid cooling pipeline is added in the air duct, and the coolant is transported to the liquid storage tank through a circulation pump, and then evenly sprayed to the parts that need heat dissipation by the nozzle. This can greatly improve the heat dissipation efficiency, especially in high power density application scenarios.

[0064] Specifically, the liquid cooling system includes a liquid storage tank, a circulation pump, a liquid cooling pipe and a nozzle. The liquid storage tank is arranged at the bottom of the box 1, and the circulation pump delivers the coolant inside to the liquid cooling pipe. The liquid cooling pipe is arranged along the air duct, and the nozzles are evenly distributed on the liquid cooling pipe to spray the coolant to the area where heat dissipation is required. In order to avoid leakage of the coolant, the liquid cooling pipe is made of corrosion-resistant material and is sealed.

[0065] In addition, in order to improve the safety and stability of the system, a low liquid level alarm and a high temperature protection switch are also set in the liquid storage tank. When the coolant level is lower than the preset value, the alarm will sound an alarm to remind the operator to add coolant in time. When the temperature is too high, the high temperature protection switch will automatically cut off the power supply to prevent the equipment from overheating and damage.

[0066] The implementation principle of this embodiment is: by introducing liquid cooling technology, the heat dissipation efficiency of the energy storage converter is further improved, especially for high-power equipment. This design can not only effectively cope with high-load conditions, but also reduce noise and vibration and improve the working environment.

[0067] Example 4

[0068] The difference between this embodiment and the above embodiment is that the design of the heat dissipation fins is optimized. Specifically, the outer heat dissipation fins 7 are arranged in multiple layers in a staggered manner, which increases the surface area and improves the heat dissipation efficiency. At the same time, the inner heat dissipation fins 6 are also optimized and adopt a wavy design to increase the turbulence effect and further improve the heat exchange effect.

[0069] Specifically, the outer heat dissipation fins 7 are divided into three layers, each layer is staggered by a certain distance, forming multiple heat dissipation channels. This design not only increases the total heat dissipation area, but also helps to increase the speed of air flow and promote the rapid dissipation of heat. The inner heat dissipation fins 6 adopt a wavy design, with fine concave and convex patterns on the surface, which increases the turbulence and improves the heat transfer coefficient.

[0070] In addition, in order to improve durability, the heat sink fins are made of aluminum alloy and anodized, which is both light and wear-resistant. Considering different application scenarios, copper alloy or stainless steel materials can also be selected to meet higher performance requirements.

[0071] The implementation principle of this embodiment is: by optimizing the design of the heat dissipation fins, the heat dissipation efficiency of the energy storage converter is significantly improved. This design is not only simple and easy to implement, but also has a high cost performance, and is particularly suitable for large-scale production applications.

[0072] Example 5

[0073] The difference between this embodiment and the above embodiment is that a backup power module is added to cope with sudden power outages. Specifically, a small battery pack is set inside the box 1. When the main power fails, the backup power module can be switched immediately to ensure the continuous operation of the cooling system.

[0074] Specifically, the backup power module includes a battery pack, a charging circuit and a switch. The battery pack capacity is sufficient to support the cooling system to operate for a period of time without an external power supply. The charging circuit is responsible for charging the battery pack under normal circumstances, and the switch automatically switches to the battery pack for power supply when the main power supply is detected to be interrupted.

[0075] In addition, in order to improve the reliability of the system, a temperature protection circuit is added to the battery pack. Once an abnormal increase in battery temperature is detected, the power supply will be automatically cut off to prevent safety hazards caused by battery overheating.

[0076] The implementation principle of this embodiment is: by adding a backup power module, the robustness of the energy storage converter heat dissipation system is improved to ensure that normal heat dissipation can be maintained under any circumstances. This design not only improves the availability of the equipment, but also reduces the losses caused by unexpected power outages.

They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
