Outdoor power supply structure and corresponding recommended specific types

Outdoor power supply refers to power equipment used in outdoor environments, which usually needs to have characteristics such as waterproof, dustproof, and high and low temperature resistance. Therefore, when designing outdoor power supplies, it is necessary to choose suitable engineering plastics to ensure their stability and reliability.




1. Shell structure

The shell structure of outdoor power supplies is usually designed to be waterproof, dustproof, and resistant to high and low temperatures to ensure their normal operation in harsh outdoor environments. Common shell structures include cylindrical, square, rectangular, etc. Among them, cylindrical shells are usually made of engineering plastics such as PBT, PA6, PC, etc; Square and rectangular shells are usually made of engineering plastics such as ABS, PC, PA6, etc.

2. Internal structure

The internal structure of outdoor power supplies usually includes components such as power boards, capacitors, transformers, etc. These components need to work properly in harsh outdoor environments such as high temperature, low temperature, and humidity. Therefore, when selecting materials for internal structures, it is necessary to consider their characteristics such as temperature resistance and moisture resistance. Common internal structural materials include engineering plastics such as PA6, PC, and ABS.

Based on the structural characteristics of outdoor power sources, it is recommended to use the following engineering plastics:



（1) PBT
PBT is a high-performance engineering plastic with excellent temperature resistance, chemical stability, and mechanical properties. Therefore, PBT is commonly used to manufacture outdoor power supplies with cylindrical shells.

(2) PA6
PA6 is a high-performance engineering plastic with excellent temperature resistance, wear resistance, impact resistance, and mechanical properties. Therefore, PA6 is often used to manufacture internal structural components such as power boards, capacitors, transformers, etc.

(3) PC
PC is a high-performance engineering plastic with excellent temperature resistance, wear resistance, impact resistance, and transparency. Therefore, PCs are commonly used to manufacture outdoor power supplies with cylindrical shells and square, rectangular shells.

(4) ABS
ABS is a commonly used engineering plastic with excellent wear resistance, impact resistance, and mechanical properties. Therefore, ABS is commonly used to manufacture outdoor power supplies with square and rectangular shells.

Choosing Engineering Plastics from an Economic Perspective

When choosing engineering plastics, economic factors are also important factors to consider. From an economic perspective, engineering plastics with higher cost-effectiveness should be chosen.

1. PBT
PBT has excellent temperature resistance and mechanical properties, but it is relatively expensive and suitable for high-end outdoor power supplies.

2. PA6
PA6 has excellent temperature resistance, wear resistance, and mechanical properties, and is relatively inexpensive, making it suitable for mid-range outdoor power supplies.

3. PC
PC has excellent temperature resistance, wear resistance, and impact resistance, and is priced high, making it suitable for high-end outdoor power supplies.

4. ABS
ABS has excellent wear resistance and impact resistance, and its price is relatively low, making it suitable for mid-range outdoor power supplies.



Selecting Engineering Plastics from a Processing Perspective

When selecting engineering plastics, it is also necessary to consider processing from a processing perspective and choose engineering plastics that are easy to process.

1. PBT
PBT processing is difficult and requires the use of high-temperature injection molding technology, which incurs high costs.

2. PA6
PA6 processing is relatively easy, and conventional injection molding processes can be used with relatively low costs.

3. PC
PC has a high degree of processing and requires high-temperature injection molding technology, which is costly.

4. ABS
ABS processing is relatively easy, and conventional injection molding processes can be used with relatively low costs.

Therefore, from a processing perspective, engineering plastics that are easy to process, such as PA6 and ABS, should be selected.

In summary, when designing outdoor power supplies, suitable engineering plastics should be selected based on factors such as shell structure, internal structure, economy, and processing angle to ensure their normal operation in harsh outdoor environments.
