Normal forced air cooling channel technical route
The direct ventilation technology uses fan to increase the air flow speed to achieve the heat dissipation effect. Generally, the front exhaust air is used to directly blow the surface of the device for heat dissipation. The direct ventilation heat dissipation method has mature technology, low cost, simple installation and energy consumption. inferior advantages.
1、Three-phase Vienna PFC design and control technology to achieve efficient energy conversion and improve power factor value
2、Three-phase SPWM control technology achieves low THD, reduces standby power consumption
3、Built-in anti-battery current backflow protection circuit to ensure high reliability of the module
4、LLC resonant circuit and control technology to achieve constant power and wide voltage output
Independent forced air cooling channel technical route
Innovation of independent air ducts in structural design and layout of key internal components, it divides the module into two layers. The upper layer is encapsulated as a device sensitive to the environment (sand, moisture, salt spray, etc.); The lower layer encapsulates the power devices with high heat generation in a fully enclosed heat sink with a sheet structure. The structural design of the module not only ensures the heat exchange efficiency but also improves the protection level. Protection level can reach IP65, which increases the life of the module, saves the cost of periodic inspection and maintenance, and improves efficiency and utilization of the charging station
1、With independent air duct is adopted, the power device is attached to the radiator case through a ceramic sheet, magnetic parts are thermally conducted to the case through glue, and the external fan dissipates heat from the radiator.
2、The circuit and electronic components are completely isolated from air, which can achieve IP65 protection level, improves the reliability of the module and adapts to harsh environments.
3、Adopts patented integrated design of magnetic components to reduce product size.
Liquid cooling technical route
The liquid cooling technology sets up a special circulation channel between the charging pile power module, cable and charging gun, and pushes the cooling liquid to circulate through the power pump to take out the heat. The heat dissipation capacity of the liquid cooling module is 10~20℃ lower than that of the forced air cooling module, noise reduction control can meet the noise-sensitive scenes requirement. The liquid cooling module also has a higher IP protection level, which is suitable for harsh scenarios such as dusty applications, reducing periodic inspection and maintenance, thereby reducing operating costs.
1、Optimizes and improves existing liquid-cooling technology, simplifies water circulate design, and improves heat dissipation efficiency
2、Adopts high-efficiency power electronic technology and software control technology, which reduces product heat consumption, adopts innovative structural layout and thermal simulation technology to realize the liquid-cooling heat exchange
3、Reduce the impact of sandstorm and salt spray with protection level of IP65, improve the reliability of the equipment and remarkably reduce the noise level
High Integration technical Route
