Abstract
Description
[Technical field]
[0001] The utility model relates to the technical field of electric dust collectors, in particular to a high-frequency power supply for centralized collection and centralized heat dissipation of electric dust collectors. [Background technology]
[0002] Nowadays, electrostatic precipitators have become an important product in the dust removal and environmental protection industry, and they play a vital role in industrial dust recovery. High-frequency power supply is an important component of electrostatic precipitators. High-frequency switching power supply is the development trend of the industry. It can provide a variety of voltage waveforms for electrostatic precipitators, ranging from pure DC to large pulse amplitude. Its cross-current characteristics can quickly extinguish sparks and quickly restore power plant energy, so it can provide the most suitable voltage waveform for specific working conditions to improve dust removal efficiency. Compared with thyristor power supply, high-frequency switching power supply also has the advantages of high conversion efficiency, small output ripple, small size, light weight, etc., and it is more efficient, more energy-saving, and lower cost. The market has basically been transformed into high-frequency power supply.
[0003] The current market trend is towards high-frequency power supplies above 2.0A. The application of high-power power supplies also increases the heat dissipation requirements of the power supply itself. The current mainstream heat dissipation methods include air cooling, self-cooling, oil cooling, and water cooling.
[0004] Air-cooled high-frequency power supplies are mainly driven by large fans, which are noisy and have poor three-proof effects, and cannot meet the requirements of places with harsh environments;
[0005] The self-cooling high-frequency power supply adopts the natural cooling method of heat exchanger and transformer. This method reduces noise, enhances the three-proof performance, and can adapt to different environmental requirements, but the heat dissipation effect is poor and cannot meet the heat dissipation requirements of high-power power supplies;
[0006] Generally, oil-cooled and water-cooled high-frequency power supplies use the same principle, with pumps for forced circulation, which effectively cools the transformer oil. However, special duct fans are required to cool other inverter units, rectifier units, and resonant circuits. This method can effectively control the temperature rise of the transformer, but it does not centrally collect and dissipate the heat from key heat sources, resulting in a complex structure that not only increases costs but also greatly increases the number of failure points. [Contents of the utility model]
[0007] The purpose of the utility model is to solve the problems in the prior art and to provide a high-frequency power supply for centralized collection and centralized heat dissipation of electrostatic precipitator heat, which can solve at least one of the above problems.
[0008] To achieve the above-mentioned purpose, the utility model proposes a high-frequency power supply for centralized collection and centralized heat dissipation of electrostatic precipitator heat, including a transformer oil tank, a heat sink, a plurality of heat sinks and a heating element. The transformer oil tank is provided with a heat sink, one side of the heat sink is provided with a heating element, and the other side is provided with a heat sink, and the heat sink is immersed in the transformer oil in the transformer oil tank.
[0009] Preferably, the heating element includes a rectifier bridge and an inverter unit.
[0010] Preferably, a transformer and a resonant capacitor are provided in the transformer oil tank.
[0011] Preferably, the device further includes a radiator, the output end of the radiator is connected to the transformer oil tank, and an oil pump is provided on the oil circuit connecting the input end of the radiator with the transformer oil tank.
[0012] Preferably, a cooling fan is provided on one side of the radiator.
[0013] Beneficial effects of the utility model: the utility model provides a heat sink on the transformer oil tank, a heating element is provided on one side of the heat sink, and a heat sink is provided on the other side, and the heat sink extends into the transformer oil tank. Compared with the prior art, the mode of centralized heat collection and centralized heat dissipation makes the overall power supply smaller in size, the overall weight is also reduced, and the production cost is reduced. At the same time, the compact structural arrangement makes maintenance more convenient.
[0014] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

[0018] See also Figure 1 , 2 The utility model discloses a high-frequency power supply for centralized collection and heat dissipation of electrostatic precipitator heat, comprising a transformer oil tank 1, a heat sink 2, a plurality of heat sinks 3 and a heating element 4. The transformer oil tank 1 is provided with a heat sink 2, one side of the heat sink 2 is provided with a heating element 4, and the other side is provided with a heat sink 3, and the heat sink 3 is immersed in the transformer oil in the transformer oil tank 1.
[0019] The heating element 4 includes a rectifier bridge and an inverter unit.
[0020] The transformer oil tank 1 is provided with a transformer and a resonant capacitor.
[0021] It also includes a radiator 5, the output end of the radiator 5 is connected to the transformer oil tank 1, and an oil pump 6 is provided on the oil circuit 8 where the input end of the radiator 5 is connected to the transformer oil tank 1.
[0022] A cooling fan 7 is provided on one side of the radiator 5 .
[0023] Working process of this utility model:
[0024] The utility model discloses a high frequency power supply for concentrated heat collection and concentrated heat dissipation of electrostatic precipitator. During operation, heating element 4 is arranged on heat dissipation plate 2, and heat is concentrated on heat dissipation plate 2 by heat conduction. Heat dissipation plate 2 is made of aluminum.
[0025] Very thin heat sinks are installed on the heat sink 2, so that heat is transferred to the transformer oil in the transformer tank 1 through the heat sink. Due to the action of the oil pump 6, the high-temperature transformer oil returns to the transformer tank 1 after dissipating heat through the radiator 5. Under the action of the cooling fan 7, the high-temperature oil undergoes heat exchange to achieve rapid cooling, and the low-temperature oil returns to the transformer tank 1, which circulates continuously, thereby well controlling the overall temperature of the power supply.
[0026] The key heat sources of high-frequency power supply are rectifier unit, inverter unit, resonant capacitor 9, and transformer, so these parts are centrally arranged in structure so that heat can be collected in a centralized manner. The rectifier bridge and inverter unit are arranged on the same heat sink, and a heat sink is arranged behind the heat sink. The heat sink is installed in the transformer oil tank so that the heat sink is completely immersed in the transformer oil. The heat of the rectifier bridge and inverter unit is transferred from the heat sink to the transformer oil through the heat sink, so that the heat of the rectifier bridge and inverter unit is transferred to the transformer oil;
[0027] The resonant capacitor and the transformer are directly arranged in the transformer box and are completely immersed in the transformer oil, so that the heat of the resonant capacitor and the transformer is transferred to the transformer oil.
[0028] The heat from the four main heat sources is collected and concentrated into the transformer oil, causing the temperature of the transformer oil to rise. The heat is then pumped through the oil circuit to the radiator, and then returns to the transformer oil tank after cooling, thus realizing oil circulation. The radiator is cooled by direct fan blowing.
[0029] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
