As we all know, the popularity of electric vehicles is already an irreversible trend. There are two types of charging piles that understand the market: air-cooled charging piles and liquid-cooled charging piles.
The main differences are different heat dissipation media and different heat dissipation speeds.
1. The heat dissipation media are different.
The air-cooled pile uses air as the medium, and the airflow is brought by the fan to achieve the cooling effect.
The liquid-cooled pile uses the circulating fluid as the medium to transfer heat to the circulating fluid and then enters the radiator to take away the heat.
2. The heat dissipation speed is different.
The specific heat capacity of liquid is large, the heat dissipation efficiency of liquid cooling is 1000-3000 times higher than that of air cooling,
and the heat dissipation speed of liquid piles is faster than that of air-cooling piles.
However, most of the air-cooled charging piles are selected in the market because of low cost and fast production cycle. As a pioneer in the charging pile market,
Bluesky has been exploring and is committed to providing customers with the best electric vehicle charging products. So can air-cooled charging piles be made better?
The heat dissipation method of mainstream air-cooled charging piles in the current market is shown in the figure below:
This kind of air inlet relies on the cooling fan suction capacity of the charging module itself and the natural wind to enter.
The air outlet is equipped with a high-power cooling fan to absorb the heat.
Ordinary charging pile manufacturers can achieve good cooling air ducts,
relying on this This cooling method can meet the needs of some customers.
During the actual use of charging piles, Blue Sky Energy collected a large amount of data and discovered the limitations of this heat dissipation effect through after-sales case analysis.
In actual use, due to weather conditions and unsatisfactory heat dissipation effects of the charging module,
the charging module is often used in a power-limited state.
Therefore, the following improvements were made:
Through repeated research and testing, a better heat dissipation method has been introduced as shown in the figure below:
This structure with an air supply fan installed at the front of the charging module and its excellent heat dissipation duct showed better heat dissipation during the test.
When running at full load for 10 minutes, the measured temperature is nearly 10 degrees Celsius lower than the structure with only a cooling fan.
At this time, the charging module can normally reach its maximum output power.
So has Bluesky, a pioneer in the charging pile industry, stopped exploring? Is this the limit of air cooling?
Blue Sky Energy gave the answer and gave a better solution!
This cooling mode is shown in the figure below:
We have adopted a semi-enclosed charging pile cabinet, using the principle of natural rise of heat energy,
so that its waterproof effect can reach a higher level, and the heat dissipation effect is twice that of the previous heat dissipation effect,
which is suitable for more severe conditions and effectively reduces It eliminates charging pile failures caused by external factors and increases the service life of charging piles.
This kind of air inlet and outlet adopts a single air direction channel design,
and the air inlet uses a powerful filter. In more demanding environments,
we design a separate air inlet, equipped with a refrigerator or heating machine to meet customer needs.
Bluesky is committed to providing customers with better charging equipment. What are the limits of air-cooled charging piles? Welcome to discuss together.
