PER535A, a system made with convenience and strength in mind, is powered by Perfectron’s INS8335C high performance motherboard. PER535A can thrive at +70℃ without processor throttling and continually presents superior 2.3 GHz clock speed. Flexible expansion slot design features 1 x PCI & PCIe slot. 16 bit DIO can meet the needs of various different applications, such automation, energy exploration, medical and defence. Wide range DC in put design with ATX power supply from 9V to 24V can protect the system from sudden current fluctuation. For applications that require extreme resistance to shock and vibration, PER535A has passed IEC 60068-2-64& IEC 60068-2-27 vibration and shock tests. In an effort to permanently vanquish the malfunction due to crash and collision, PER535A is equipped with four rubber foot stands at the front side to prevent possible damages to I/O and power switch. With industrial grade handles assembled on two sides of the system, easy installation and utmost mobility are warranted.

Integrated thermal solution – the incorporation of four pure copper heat pipes and an copper heat sink

INS8335A, with its dynamic 4-core 45W core i7-3610QE processor, demands an equal high level thermal solution. To achieve maximum heat dissipation, the design and implementation of heat pipes is the golden key. In this case, a copper heat sink and passively cooled enclosure is implemented to establish an effective dissipation environment. The structure of four pure copper heat pipes is to ensure supreme thermal efficiency. The heat pipes are capable of prompt dissipation of the heat generated by the CPU’s inner core while it’s computing. According to Perfectron’s testing result, each pure copper heat pipe has the ability to dissipate 9w of heat. The combination of four heat pipes pushes the dissipation ability to a new level. Our tailor-made, precision-aimed integral structural heat sink and embedded heat pipes constitute an excellent fanless thermal solution. When the CPU hits 100% full potency, the implementation of four 6mm (minimum) pure copper heat pipes can keep it running at full speed – 2.3 Ghz!

Effective cooling devices for maximum heat dissipation

Perfectron’s unique heat sink and heat pipe are designed with precision. Each of the key heat-dissipating components is tailor-made in accordance with different interior and exterior structure. Unlike traditional solutions that utilize aluminum as the dissipating media for CPU and fin. We insist on incorporating 99% pure copper heat spreader, which is eight times higher in density than aluminum. Our tailor-made pure copper heat spreader is treated with the most precise CNC technology, cutting four 6.1mm wide track so that the 6mm wide heat pipes can fit seamlessly. Compared with conventional solid heat conductors, such as aluminum, copper, granite, and graphite, of which thermal conductivity ranges from only 250 W/m•K to 1,500 W/m•K, Perfectorn’s effective heat pipe design, with impressively high thermal conductivity (5000 W/m•K to 200000 W/m•K) that is 40 times higher than standard aluminum, is guaranteed to charge the system to the maximum turbo speed with minimum overall impact.

Thermal Measurement

PERFECTRON provides real lab testing figures to show how CPU performance is with each tailor made thermal kits as important references and design guide for system engineers. For system integration, the crucial challenge is the operation performance under high temperature, thus PERFECTRON conducts long time experiments to make sure the superior testing result for all critical missions. By revealing temperature at processor T junction, processor die and heat sink, PERFECTRON is able to analyse the thermal solution we designed achieves maximum efficacy and observe CPU performance. The high temperature testing takes 5 hours which at each temperature point we burn in PER535A for one hour, from +50 to +85°C.





Effective cooling solution for maximum heat dissipation:

PERFECTRON implements unique cooling solution with copper heat spreader, pure copper heat pipe and aluminum heat sink for maximum heat dissipation. With the aluminum heat sink enclosure allows dual-sided heat dissipation. We especially adopt the physical property of copper and aluminum, the copper heat spreader touches the heat source - processor and chipset and absorbs the heat rapidly, the heat then transfer to heat pipe; heat pipe is two-phase heat transfer involves the liquid-vapor phase change of a working fluid, the aluminum heat sink dissipates the heat into surrounding air promptly. With the benefits of fanless design, PER535A can ensure high reliability and stability while working under wide range temperature from -40 up to 70°C.

Thermal Pad
After countless experiments, PERFECTRON’s experienced engineer team has learned valuable lessons about the perfect thickness of thermal pad from failures.

 •Precise design of thermal pad: the gap between CPU die and heat sink should be less than 1mm.

Copper & Aluminum Heat Spreader
 •The outer layer contains 96% of aluminum, the height is 23.5mm and it weighs 142g.

 •The inner layer contains 99.9% of copper, the height is 23.5mm and it weighs 173g.


Pure Copper Heat Pipe
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.

 •The longer ones are 365mm in length, 99.9% purity of copper.

 •The shorter ones are 157mm in length, 99.9% purity of copper.

 • High heat conductivity efficiency up to 5000.


Dual Sided Aluminum Heat Sink

 •The heat sink each weighs 650g, and the height is 3.8cm

 •The heat conducted by the heat sink will be dissipated by the aluminum heat sink placed on
the two sides.

 • Aluminum has higher efficiency in heat dissipation.
