Thermal solution for fanless system design




7starlake designs a unique enclosure that is able to stack together both horizontally and vertically. The aluminum heat sink enclosure allows dual-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, SR200-SG 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 up to


Stunning resistance of shock and vibration

PERFESR200-SG stands for Stack & Rack which represents that SR200-SG can be stackable and be racked in cabinet. Moreover, SR200-SG has key components soldered onboard to eliminate risk of harm caused by vibration. It not only supports Intel CPU onboard but also memory and storage onboard which drastically enhance the resistance of vibration and shock. It is worth noting that NVIDIA graphic module is connected by PCIe/104 connector, instead of using PCIe x16. When stacking together, the PCIe/104 connector delivers exceeding solidity due to the four corner mounting holes and the three bank(156-pin). It removes the concern about loosen connection caused by shock & vibration. Combining critical components soldering onboard and solid PCIe/104 connection, it is also compliant to MIL-STD 810G standard, can withstand 5g vibration, 100g single shocks and 50g multiple shocks.




System main board: EBX SBC-OXY5737A


1. Intel® Core i7 CPU soldering onboard

SR200-SG is based on EBX SBC—OXY5737A, powered by Intel Ivy Bridge i7-4700EQ quad core processor plus QM87 chipset soldered onboard. With CPU soldering onboard, there is less conduction of heat and high density interconnection between the motherboard and the components, which reduces the MB from the crisis of overheating. Apart from overheating, soldering onboard also provides the best level of shock and vibration protection, removing the unnecessary concern about poor connection that CPU socket type may bring.


2. Four Independent DisplayPort

SR200-SG has added on NVIDIA graphic card through PCIe/104 interface, supporting 4 independent DisplayPort which is driven by GPU NVIDIA®1050Ti CUDA 765 GDDR5-4GB/GTX 1650 CUDA896 GDDR5-4GB/GTX 1660S CUDA1408 GDDR6-6GB GPU. Representing its high computing performance and consumes power at 35W maximum. Connecting by PCIe/104 interface which enhance the resistance of shock and vibration as the connector allows nearly seamless connecting.


3. Wide Range DC input

For military and heavy duty vehicle applications, instable voltage always brings headaches about damaging the electric components. SR200-SG supports 9V to 36V DC-in, the flexible acceptance of inconsistent power input makes it capable of surviving tough engine cranks and transient over-voltage situations.

The SR200-SG 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.

Thermal Solution

Elaborate thermal design

For intellectual video wall and defense control room applications, the system is always working 24/7 nonstop operation which makes the system always keeps at high temperatures. Therefore the importance of extended operating temperature is undoubted. 7starlake experts develop a brand new thermal design which involves segmentation type thermal design, integrating solidly with heat pipe, heat spreader and heat sink which allows SR200-SG to survive from -20 to +60°C. The thermal solution flexibly maximize the metal characteristic, using copper heat spreader to absorb heat directly from heat sources, then using heat pipe to transfer heat to aluminum heat sink. The copper heat pipe is the key factor among the whole thermal design. The heat conductivity coefficient of heat pipe can be up to 5000, nearly 12 times better than copper heat spreader. With a perfect combination of copper plus aluminum thermal kit which efficiently manage the heat dissipation up to 60°C.



Patent Designed Heat Sink

The heat sink is made by heat radiating material which is also combining with special CNC cutting, further forged into high efficient heat dissipation metal.

Copper Heat Pipe

The heat pipes are embedded in the heat sink to ensure 100% tight integration for efficient dissipation. Heat pipe transfers heat from the heat sources to the heat sink over relatively long distance. Two-phase heat transfer involves the liquid-vapor phase change of a working fluid.

2 heat pipes of 8.0 mm width diameter, and 225mm length; each contains 56-61% purity of copper. U shape design reach the utmost efficiency. High heat conductivity coefficient up to 5000

PCIe/104(StackPC) carrier module is designed to offer up to 6 independent displays by MXM interface under extended temperature from -40°C ~ 85°C. SK220 is equipped with 6 x miniDP, 1 x VGA (2 x 5 pin header) which can support most MXM graphic cards from NVIDIA.


Copper Heat Spreader for Overall System

The copper heat spreader directly touches heat source which is generated from power voltage transferring.

99.9 % purity of copper, weighs 470 g and consumes 113.9 cm2 15.5 mm height to fulfill the gap between motherboard and heat sink. The tailor made design help to transfer the heat directly to uppers aluminum heat sink.


CPU Host Board-OXY5737A

7starlake QM87 EBX SBC is installed in the middle of the system as a cutoff point, dividing segmentation type thermal design into upper and lower module. Upper thermal module is applied to cool down the heat generated from graphic card; while the lower thermal module is applied to cool down the heat from CPU module.


Copper Heat Spreader for CPU

The copper heat spreader directly touches heat sources from CPU and chipset.

99.9 % purity of copper, weighs 80 g and consumes 36 cm2 3.4 mm height to fulfill the gap between OXY5737A and heat sink enclosure Nickel plated to prevent corrosion and rust after long-term use Tailor-made two bulges on heat spreader correspond to the placement of CPU and chipset on OXY5737A.
