背景技术Background technique
目前，现有的电气散热技术多数采用铝型材传导热量强迫风冷散热，或油传导热能，再用风或水二次换热的散热方法。然而热量本身就是能源，这些通过消耗电能来散热的方案，均为耗能型方案。At present, most of the existing electrical heat dissipation technologies use aluminum profiles to conduct heat and force air cooling to dissipate heat, or oil to conduct heat energy, and then use wind or water for secondary heat exchange. However, heat itself is energy, and these schemes that dissipate heat by consuming electrical energy are all energy-consuming schemes.
实用当中由于油有燃烧的风险、水有泄漏导电的风险，所以绝大多数的电气设备采用强迫风冷的方案。风冷须有流动空气，但空气中的水汽和灰尘是电气设备安全运行的两大危害；尤其是电气箱柜在工矿企业以及车船等使用环境当中，这两大危害尤为突出；复杂的变频器等设备受这些环境因素损坏的比例非常高，严重影响使用寿命。In practice, because the oil has the risk of burning and the water has the risk of leakage and conduction, the vast majority of electrical equipment adopts the forced air cooling scheme. Air cooling must have flowing air, but water vapor and dust in the air are the two major hazards to the safe operation of electrical equipment; especially in the use environment of industrial and mining enterprises, vehicles and ships, these two hazards are particularly prominent; complex inverters The proportion of equipment damaged by these environmental factors is very high, which seriously affects the service life.

There are micro oil pumps and heat-dissipating coils outside the fully enclosed cabinet. The heat-dissipating medium liquid inlet end of the double-hole aluminum heat-dissipating medium circulation pipes The liquid inlet end of the heat exchange coil is connected to the liquid outlet of the micro oil pump through the connecting pipe, and the liquid inlet end of the micro oil pump is connected to the liquid outlet of the cooling coil through the connecting pipe. The liquid inlet end of the heat dissipation coil is connected to the liquid outlet end of the heat dissipation medium of the double hole aluminum heat dissipation medium circulation pipe through the connecting pipe. The coil tube constitutes the circulating heat conduction pipeline of the heat dissipation medium; the positive and negative poles of the power supply of the micro oil pump are respectively connected with the positive and negative poles of the power supply of the thermoelectric semiconductor power generation board connected in series.
在双孔型铝和换热盘管之间设有将两者隔开的隔板，换热盘管处于隔板和全封闭柜体的后板内壁之间形成换热风道。A partition is arranged between the double-hole aluminum and the heat exchange coil to separate the two, and the heat exchange coil is formed between the partition and the inner wall of the rear plate of the fully enclosed cabinet to form a heat exchange air duct.
在柜外散热盘管的下方设有给散热盘管进行风冷的电风扇，电风扇的正负极分别与串联在一起的热电半导体发电板电源的正负极连接。An electric fan for air-cooling the heat dissipation coil is arranged below the heat dissipation coil outside the cabinet, and the positive and negative electrodes of the electric fan are respectively connected with the positive and negative electrodes of the thermoelectric semiconductor power generation board power supply connected in series.
双孔型铝中的散热介质流通管道的形状为“U”形。The shape of the heat dissipation medium circulation pipe in the double-hole aluminum is "U" shape.
散热介质流通管道的散热介质为硅油或纯水。The heat dissipation medium of the heat dissipation medium circulation pipeline is silicone oil or pure water.
本实用新型包括热电半导体发电板、双孔型铝、换热盘管、微型油泵、散热盘管和电风扇，本实用新型用具有散热介质流通管道的双孔型铝替换电气设备主要的发热功率元件（如IGBT等）的风冷散热型铝，在全封闭柜体内的双孔型铝与发热功率元件之间安装有（Bi2Te3基）热电半导体发电元件，双孔型铝的散热介质流通管道、换热盘管、微型油泵、散热盘管通过连接管的依次连接构成散热介质密闭的循环导热管路，双孔型铝和换热盘管在全封闭柜体内，散热盘管在全封闭柜体外，散热介质通过换热盘管→双孔型铝→柜外散热盘管→循环油泵→回到换热盘管，完成循环，目的是把全封闭柜体内的主要发热部位的热量，重点搜集，用微型油泵驱动散热介质循环，把热量导出全封闭柜体外。由于柜体为完全封闭，不与外部环境发生物质交换，本实用新型利用需散失的热能转化的电能驱动微型油泵和电风扇运转消耗热量，同时导出多余的热量，保持全封闭柜体内的温度稳定在设备安全运行的温度之下，不额外消耗能源。如发热功率元件的发热量小，则热电半导体发电板发出的电压低，微型油泵的运转速度相应就慢，密闭的循环导热管路里的散热介质被驱动的流速就慢，导出柜体外的热量就少；如发热功率元件发热量大，热电半导体发电板发出的电压就高，微型油泵运转速度相应就快，密闭的循环导热管路里的散热介质被驱动的流速就快，导出的热量就多，最终形成一个传导热平衡。并且一旦全封闭柜体内的热源消失、出现不需要散热的情况，热电半导体发电板亦停止发电，微型油泵、电风扇也立即停止工作。在发热量不大的情况下，本实用新型可以利用热的散热介质上升、冷的散热介质下降形成自循环导热，而微型油泵不需工作。The utility model includes a thermoelectric semiconductor power generation plate, a double-hole type aluminum, a heat exchange coil, a micro oil pump, a heat dissipation coil and an electric fan. Air-cooled heat-dissipating aluminum for components (such as IGBTs, etc.), a (Bi 2 Te 3 -based) thermoelectric semiconductor power generation element is installed between the double-hole aluminum and the heating power element in the fully enclosed cabinet, and the heat-dissipating medium of the double-hole aluminum The circulation pipes, heat exchange coils, micro oil pumps, and heat dissipation coils are connected in sequence through the connecting pipes to form a closed circulating heat conduction pipeline for the heat dissipation medium. Outside the closed cabinet, the heat dissipation medium passes through the heat exchange coil → double-hole aluminum → the heat dissipation coil outside the cabinet → circulating oil pump → back to the heat exchange coil to complete the cycle. Focus on collection, use a micro oil pump to drive the circulation of the cooling medium, and export the heat out of the fully enclosed cabinet. Because the cabinet is completely closed and does not exchange material with the external environment, the utility model utilizes the electric energy converted from the heat energy to be dissipated to drive the micro oil pump and the electric fan to run and consume heat, and at the same time, the excess heat is exported to keep the temperature in the fully closed cabinet stable. Below the temperature at which the device is safe to operate, no additional energy is consumed. If the calorific value of the heating power element is small, the voltage emitted by the thermoelectric semiconductor power generation board is low, the operation speed of the micro oil pump is correspondingly slow, and the flow rate of the heat dissipation medium in the closed circulating heat conduction pipeline is driven slowly, leading to the heat outside the cabinet. If the heating power element generates a large amount of heat, the voltage emitted by the thermoelectric semiconductor power generation board will be high, the operation speed of the micro oil pump will be correspondingly fast, and the flow rate of the heat dissipation medium in the closed circulating heat conduction pipeline will be driven faster, and the heat generated will be reduced. more, eventually forming a conduction heat balance. And once the heat source in the fully enclosed cabinet disappears and there is no need for heat dissipation, the thermoelectric semiconductor power generation board also stops generating electricity, and the micro oil pump and electric fan also stop working immediately. Under the circumstance that the calorific value is not large, the utility model can utilize the rise of the hot radiating medium and the descending of the cold radiating medium to form self-circulation heat conduction, and the micro oil pump does not need to work.

Drive the micro oil pump to force the circulation of the cooling medium and force the electric fan to work, consume heat energy in the form of electrical energy, and at the same time discharge the excess heat out of the cabinet.
本实用新型的全封闭柜体采用IP66标准设计，隔绝柜内外环境的物质交换，防止外部环境物质对电气设备的不利影响，进出一、二次线路端子排及管路在进出柜体处均用热熔硅胶等密封材料封装，有效防止灰尘和水汽进入，确保箱体内外气、水隔绝，确保箱柜内的小环境物质相对稳定。The fully enclosed cabinet of the utility model adopts the IP66 standard design, which isolates the material exchange between the inside and outside of the cabinet, and prevents the adverse effects of external environmental substances on electrical equipment. It is encapsulated with sealing materials such as hot-melt silica gel, which can effectively prevent the entry of dust and water vapor, ensure the isolation of air and water inside and outside the box, and ensure that the small environmental substances in the cabinet are relatively stable.
本实用新型在柜体内通过隔板将发热功率元件和换热盘管隔开，形成两条均垂直于地面的循环换热风道，上下连通，以保证发热功率元件和换热盘管之间的风道畅通，利用热空气上升、冷空气下降的原理形成自循环流通换热，以保证柜体内的小环境温度稳定均匀，防止局部高温的出现。In the utility model, the heating power element and the heat exchange coil are separated by the partition plate in the cabinet, so as to form two circulating heat exchange air ducts that are both perpendicular to the ground, and communicate up and down, so as to ensure the space between the heating power element and the heat exchange coil. The air duct of the cabinet is unobstructed, and the principle of hot air rising and cold air falling is used to form self-circulation circulation heat exchange, so as to ensure the stable and uniform temperature of the small environment in the cabinet and prevent the occurrence of local high temperature.
因此，本实用新型具有应用热电半导体发电元件消耗热能来发电、在消耗热量的同时利用该电能实现全封闭柜体内的封闭环境自冷降温散热、用于IP66防护等级的电气箱柜、能够自适应、节能高效、绿色环保的优点，它利用绝缘阻燃的为硅油或纯水为散热介质，自动传导热量，既满足设备防护要求，无需电源又能满足散热需要，从而解决了全封闭柜体无法通风散热的矛盾，不仅能在保护电气设备免受水汽、灰尘侵害的同时，而且能利用自身热能为动力自适应的满足电气设备的散热需要，是一种安全、节能和高效的兼顾散热和防护设备的两全装置。Therefore, the utility model has the advantages of using thermoelectric semiconductor power generation elements to consume thermal energy to generate electricity, and using the electrical energy to achieve self-cooling, cooling, and heat dissipation in a closed environment in a fully enclosed cabinet while consuming heat. , energy saving, high efficiency, green environmental protection advantages, it uses insulating and flame retardant silicone oil or pure water as heat dissipation medium, and automatically conducts heat, which not only meets equipment protection requirements, but also meets heat dissipation needs without power supply, thus solving the problem of fully enclosed cabinets. The contradiction between ventilation and heat dissipation can not only protect electrical equipment from water vapor and dust, but also use its own thermal energy as power to adaptively meet the heat dissipation needs of electrical equipment.
