固态铝电解电容的应用领域正在进入一些新兴的领域中,比如:新能源汽车、充电桩、智能电子设备等等,新兴行业的快速发展也更是增加了对于固态铝电解电容的需求。随着新能源汽车的发展,车型的丰富,不论是公交车、出租车、小型轿车都研发出了纯电动车,可见铝电解电容的市场大为可观。
The application field of solid-state aluminum electrolytic capacitors is entering some emerging fields, such as new energy vehicles, charging piles, intelligent electronic devices, etc. the rapid development of emerging industries also increases the demand for solid-state aluminum electrolytic capacitors. With the development of new energy vehicles and the abundance of models, pure electric vehicles have been developed in buses, taxis and small cars. It can be seen that the market of aluminum electrolytic capacitors is considerable.
对安全性要求较高的汽车市场而言,所有的电子元器件包括固态铝电解电容的选择与设计,都要以安全性和长久性为前提。所以固态铝电解电容,选型时也要特别注意耐压、耐高温、失效阈值等方面的要求;在设计中,耐压、容量也应留有足够的余量。
For the automotive market with high safety requirements, the selection and design of all electronic components, including solid-state aluminum electrolytic capacitors, should be based on safety and durability. Therefore, special attention should be paid to the requirements of withstand voltage, high temperature resistance and failure threshold when selecting solid aluminum electrolytic capacitor; In the design, sufficient margin shall be reserved for withstand voltage and capacity.
用于汽车ECU的电容器对耐温性能有严格要求,汽车行驶时必须受发动机辐射热影响,在高温环境下工作,而停车时受外界较低温度影响又需具有耐低温性能。具体地说,是要求在-40℃~-+125℃,温度范围较大,具有较高的热稳定性。
The capacitor used for automobile ECU has strict requirements for temperature resistance. When driving, the automobile must be affected by the radiant heat of the engine and work in a high temperature environment. When parking, it must have low temperature resistance due to the influence of low external temperature. Specifically, it is required to have a large temperature range of - 40 ℃ ~ - + 125 ℃ and high thermal stability.
除正常工作要求外,还需要确保工作温度范围更长的寿命(约4000小时)。影响电解电容寿命的因素主要是高温,温度越高电解液的挥发速率越快,电解电容寿命也随着温度的升高而下降。采用高密封性、抑制电解液蒸发等方法,可达到延长产品寿命的目的,即采用高密封性的封口材料,达到高温热稳定。
In addition to normal operating requirements, it is also necessary to ensure a longer service life in the operating temperature range (about 4000 hours). The main factor affecting the life of electrolytic capacitor is high temperature. The higher the temperature, the faster the volatilization rate of electrolyte, and the life of electrolytic capacitor decreases with the increase of temperature. The purpose of prolonging product life can be achieved by adopting methods such as high sealing and inhibiting electrolyte evaporation, that is, using sealing materials with high sealing to achieve high temperature thermal stability.
选择芯温低固态铝电解电容,可保证较长的电容器使用寿命。电解质芯温度越低,使用寿命就会成倍增长,选择优质的固态铝电解电容要比廉价的便宜得多。我们在使用电解质产品时,可改进“电容散热装置”,以解决由于“爆晒”对“铝电解电容寿命”产生的影响。
The selection of solid aluminum electrolytic capacitor with low core temperature can ensure a long service life of the capacitor. The lower the temperature of the electrolyte core, the service life will be doubled. Choosing high-quality solid-state aluminum electrolytic capacitors is much cheaper than cheap ones. When using electrolyte products, we can improve the "capacitor heat dissipation device" to solve the impact of "exposure" on the "life of aluminum electrolytic capacitors".
