Pain Point Identification

The customer adopted a sealed fanless industrial mini PC for workshop equipment data acquisition and PLC communication. During long-term heavy-load operation, the sealed chassis limited heat dissipation, resulting in excessive heat accumulation inside the enclosure. The original passive cooling design could not meet the requirement of continuous full load operation, which brought potential risks to system stability. The customer requested a customized chassis cooling modification.

Custom Solution Introduction

Shenzhen Helor Cloud Computer Co.,Ltd. delivered a structural customization solution based on the customer’s working conditions. We opened an air vent on the top of the all-aluminum chassis and installed a cooling fan at the reserved position. The original aluminum fin passive cooling structure was retained, forming a hybrid cooling system combining passive heat dissipation and active air cooling. All I/O ports, GPIO terminals, serial ports and LAN ports remain unchanged, and the mainboard pin definition and overall mounting dimensions are preserved for compatibility with the original control cabinet and wiring layout.

Value After Retrofit

The hybrid cooling setup accelerates the exhaust of hot air inside the enclosure and relieves heat buildup in the sealed cavity, reducing high temperature risks during extended heavy load operation. The industrial computer can run stably for 365days*24hours continuous operation in on-site industrial environments. Since mounting holes and external interfaces stay the same, the customer does not need to redesign fixtures or adjust wiring programs, cutting on-site replacement and debugging costs. This solution provides a practical structural customization option for sealed fanless industrial PCs with insufficient heat dissipation.
