The Core Brain of Driverless Vehicle

Driverless vehicle requires multiple sensors such as LiDARs, cameras to play as its eyes for environment and obstacle detection. The image produced by LiDARs and cameras need to be analyzed, compared and one step further come up with a decision-making result to indicate control system to react to the situation. CPT320 is perfectly match with the demand of driverless technology. With NVIDIA®GTX1660 GPU (CUDA Cores:1408), image provided by sensors can be efficiently processed and analyzed, plus Intel® 9th Gen Corei7 CPU and DDR4 32GB memory which greatly enhance the working speed of data analysis. Possessing 5 DisplayPorts, CPT320 is able to display multiple images on the vehicle, including the direct image detected by LiDARs and cameras, passenger information and operation interface. CPT320 is undoubtedly an outstanding solution to play an important role in self-driving technology and AI fusion.



Unique Challenges

CPT320.png CPT320-01.png


Patented Thermal Solution

7starlake designs a unique enclosure that is able to stack together both horizontally and vertically. The aluminum heat sink enclosure of CPT320 allows quad-sided heat dissipation. 7starlake exclusively adopts special heat radiating material and combining with special CNC cutting, further forged into a lavish sophisticated metal. Apart from the special heat sink enclosure, CPT320 innovatively adopts two kinds of copper heat spreader. The shape and the size of the spreader are tailor-made based on the heat sources placement of CPU module and graphic module. In view of the gap difference between motherboard and heat sink, 7starlake builds two heat spreaders in different thicknesses. Combining all these exclusive thermal designs can alternatively replace traditional fan, and also ensures high reliability and stability while working under wide range temperature from -20°C up to 60°C.


MIL-STD-810G designed for high environmental adaptation

CPT320 is designed to meet MIL-STD-810G standard for shock and vibration. MIL-STD-810G standard is considered the upmost principle, which guarantees the system achieves superior quality and stability when operate under various environment, especially applied in vehicle, which can possibly run through unpredictable terrain, causing sudden shock or occasional vibration.

The CPT320 offers highly effectively heat conductive and heat convective thermal solutions to meet the demands of customers’ extended temperature requirements. The heat conductive solutions uses an aluminum flat mass to place in direct contact with the processor and chipset, the heat from chips then transfers it to the case of the system. In addition, the convective thermal solutions introduce airflow directed to move across the surface of a fin style heatsink placed on top of the processor and chipset. This can be done with the aid of an appropriately sized fan placed in top of the fin style heatsink. Alternately, enclosure airflow can be routed to flow across a fin style heatsink.
