52×38mm Aluminum Power Control Module Enclosure

Boyuan 52×38mm aluminum enclosure is a mid-sized electronic device housing manufactured with an aluminum alloy extrusion structure, with an external cross-section size of 52mm (width) × 38mm (height), and the length can be customized arbitrarily according to actual equipment requirements.

The product is formed by aluminum profile extrusion, with a fixed main body cross-section size. It can be cut according to the actual length of the equipment, and final assembly is completed through end plates, CNC machining, and other supporting processes.

The aluminum extrusion electronic enclosure can be designed with corresponding mounting slots or support structures according to the internal structure, for installing PCBs and other electronic components. The interior of the housing is designed with standard circuit board card slots, and the PCB can be directly inserted and fixed without additional screws, greatly improving assembly efficiency.

Compared with plastic boxes, aluminum alloy enclosures have better structural strength and a metal texture, and can achieve custom structures such as interfaces, mounting holes, threaded holes, and slots through CNC machining.

Boyuan Hardware has focused on aluminum enclosure and aluminum chassis manufacturing for over 20 years, with approximately 10,000 square meters of production factory space, and can provide custom aluminum enclosure machining according to customer drawings, samples, or size requirements.

Core Advantages

01 | 52×38mm Ample Space Design

The 52mm wide × 38mm high cross-section size provides ample internal space for mid-sized electronic equipment.

The 52mm width can accommodate wider PCB layouts and side-by-side design of multiple interfaces, supporting multi-channel input/output interface layouts; the 38mm height provides greater component mounting space, can accommodate taller components such as electrolytic capacitors (typically 25-35mm in height), transformers, heat sinks, relays, and inductors, and also supports double-sided PCB design, meeting the integration needs of complex circuit systems.

02 | Aluminum Extrusion Structure

The 52×38mm Aluminum Power Control Module Enclosure body is formed by aluminum alloy profile extrusion. The cross-section size of the aluminum extrusion enclosure is fixed, while the length can be cut according to actual product requirements. Therefore, the same specification enclosure can adapt to PCBs and electronic modules of different lengths. This structure is especially suitable for electronic products requiring series development.

03 | Suitable for PCB Mounting

The aluminum extrusion electronic enclosure can be designed with corresponding mounting slots or support structures according to the internal structure, for installing PCBs and other electronic components. The interior is standard-equipped with circuit board card slots, and the PCB can be directly inserted and fixed without additional screws. The 38mm height can accommodate double-layer PCB stacking or high-power devices with heat sinks, providing a reliable packaging solution for high-power electronic equipment.

04 | CNC Custom Machining Support

The standard profile is only the starting point. Boyuan Hardware can perform CNC machining on the 52×38mm aluminum enclosure according to customer drawings, including:

• Interface openings (USB, RJ45, aviation plugs, BNC interfaces, power interfaces, etc.)
• Screw holes and positioning holes
• Threaded holes and counterbore holes
• Heat dissipation slots and ventilation holes
• Screen window openings
• Button holes and switch holes
• Grooves and steps
• Chamfering
• Other custom structures

05 | Length Customizable to Product

52×38mm is the cross-section specification of the enclosure, and the product length can be cut according to the actual equipment dimensions. The specific machinable length is confirmed according to material, surface treatment, and product requirements.

06 | Efficient Heat Dissipation Performance

The thermal conductivity of aluminum alloy is about 200W/(m·K). Combined with the larger surface area and ample internal space of 52×38mm, it can effectively conduct and dissipate heat generated by internal components. For equipment with large heat generation such as power modules and power amplifiers, the aluminum enclosure itself is an efficient heat sink, which can extend equipment service life.

07 | Metal Enclosure Combines Structure and Appearance

Aluminum alloy is lightweight and has good structural performance, while retaining a natural metal texture. Through surface treatments such as brushing, sandblasting, and anodizing, different appearance effects can be obtained, giving electronic equipment a more professional product appearance.

What Products Is the 52×38mm Aluminum Enclosure Suitable For?

52×38mm Aluminum Power Control Module Enclosure belongs to the ample-space aluminum enclosure category — the 52mm width supports side-by-side layout of multiple interfaces, and the 38mm height provides ample vertical space for taller components and heat sinks. The 38mm height is the core feature that distinguishes this specification from thin enclosures, enabling it to carry electronic equipment with greater power and taller components, making it an ideal packaging choice for mid-sized electronic equipment.

1. Power Modules

The ample space design of 52×38mm is very suitable for various power products:

• Switching power supply modules
• Power adapters
• Vehicle power supply enclosures
• Inverter enclosures
• Rectifier aluminum housings
• DC-DC converter modules
• UPS power supply modules
• Charger modules
• Battery management system (BMS) enclosures
• Supercapacitor module enclosures

Why is 52×38mm suitable for power modules? Power modules usually need to accommodate taller components such as electrolytic capacitors (typically 25-35mm in height), transformers, heat sinks, and inductors. The 38mm height provides ample mounting space and can easily accommodate electrolytic capacitors around 30mm in height. At the same time, the 52mm width can accommodate wide PCB layouts, supporting multi-channel input/output interfaces, and the aluminum alloy material also helps high-power devices dissipate heat efficiently.

2. Power Amplifiers and Audio Equipment

• Audio power amplifiers
• Signal amplifier modules
• RF power amplifiers
• Professional amplifier enclosures
• Car amplifier modules

Why is 52×38mm suitable for amplifiers? Power amplifiers need relatively large internal space to accommodate amplifier circuits, heat sinks, and power supply sections. The 38mm height can install taller components and heat sinks, and combined with the large-area aluminum alloy enclosure of 52mm width for heat dissipation, it is suitable for audio and RF amplifier equipment with large heat generation.

3. Industrial Control and Automation Modules

• Industrial controllers
• Programmable logic controller (PLC) modules
• Motion control modules
• Motor drive modules
• Inverter modules
• I/O expansion modules
• Automation control boxes
• Robot control modules

Why is 52×38mm suitable for industrial control modules? Industrial control modules usually need to accommodate many interfaces (RS232, RS485, CAN, Ethernet, etc.) and larger-sized control boards. The 52mm width can accommodate multiple interfaces side by side, and the 38mm height can install power devices and relay modules with heat sinks.

4. Measuring Instruments and Testing Equipment

• Oscilloscope modules
• Signal generator enclosures
• Data acquisition instruments
• Power analyzers
• Spectrum analysis modules
• Hardness testing instruments
• Ultrasonic testing equipment
• Flow meter/level meter enclosures
• Multimeter modules

Why is 52×38mm suitable for measuring instruments? Measuring instruments need larger PCB layouts to accommodate signal processing circuits and multiple interfaces. The 52mm width can accommodate standard wide PCBs, and the 38mm height can accommodate components such as transformers and relays. At the same time, the aluminum alloy enclosure provides good electromagnetic shielding performance, ensuring measurement accuracy.

5. Communication and Network Equipment

• Communication base station modules
