Key points of outdoor power supply enclosure design

How to design an outdoor power enclosure？

The most common outdoor power supply enclosure on the market is divided into plastic enclosure and aluminum alloy case. The plastic enclosure often uses engineering plastic, which is very fragile in case of collision and fall. Aluminum alloy enclosurehas two advantages: fast heat dissipation and strong impact resistance, and high processing cost.

According to the market research, we know from the current power brands that:

1. Outdoor power enclosures of each brand are mostly made of plastic, with various shapes and a sense of design.

2. According to the ratio of battery capacity to enclosure volume, the size of power supply increases with the increase of battery capacity, and the ratio of the top three is similar. It can be seen that their manufacturing process has little influence on the size of shell

3. The mainstream brand internal structure includes inverter, battery pack, screen circuit board, charging module circuit board, cooling fan and built-in radiator.

4. There are many fixed handles.

Most outdoor project box supplies require aluminum enclosures. Now let's talk about the advantages of aluminum housing.

The heat can be emitted from the aluminum alloy shell, which not only avoids the noise from the cooling fan, but also greatly prevents the external moisture, dust and impurities from entering the interior, which is an incomparable advantage of the plastic shell.

The whole machine can reach the IP52 protection level by cooperating with the double layer treatment of car filling, built-in blocking of AC interface, closed structure and other processes.

Durability: aluminum can be largely waterproof, fireproof, anti falling, anti impact, wear-resistant and anti-corrosion.

The cost of sheet metal bending is low and light. The integrity of profile processing is strong. With a few plastics, it can achieve better protection performance. The custom waterproof box can also bear the power supply with larger battery capacity.
