- Thermal solution for fanless system– the incorporation of two pure copper heat pipes and aluminum heat sink
-
Thermal design is the solution for the maximum reduction of heat. With upper passive aluminum heat sink and cooled aluminum enclosure is implemented to create an effective dissipation environment. With two pure high efficiency copper heat pipes plus aluminum heat sink to ensure maximum thermal efficiency. Copper vacuum Heat-Pipe has effective thermal conductivities that range from 5,000 W/m•K to 200,000 W/m•K to effectively transfer heat from the heat source to the heat sink. This advanced thermal solution enables system to operate smoothly under temperature range -40 to 80°C -without processor throttling.
- Effective cooling solution for maximum heat dissipation
-
Perfectron implements unique cooling solution with the copper heat spreader and aluminum heat sink. To adopt the physical property of copper and aluminum, the copper heat spreader touches the heat source - processor and chipset and absorbs the heat rapidly, heat is then transferred to upper aluminum heat sink; the aluminum heat sink dissipates the heat into surrounding air promptly. The heat sink design with high and low shape to create temperature difference then produce airflow, the wave lines on the lateral side of heat sink can increase the dissipating interface up to 30 to 40%. Through above unique design could achieve maximum heat dissipation.
- Installation Instruction
-
Procedure:
Stick thermal pad on CPU and chipset, and then place passive heat sink on thermal pad.
1.Thermal Pad
Thermal pad is aid the conduction of heat away from the component being cooled (such as CPU or chip) and into the heat sink.- The unit of Heat Transfer Coefficient for thermal pad is W/m.K. The higher the Heat Transfer Coefficient number is, the better thermal conductivity for thermal pad could reach. PERFECTRON adopts thermal pad with 17 W/m.K which is military standard level that can guarantee the maximum thermal conductivity between components and heat sink
2.Aluminum Passive Heat Sink
Heat sink is known for lowering the temperature by dissipating heat into the surrounding air. PERFECTRON implements aluminum heat sink instead of copper because aluminum can dissipate the heat more rapidly than copper due to metal characteristic- It contains 96 % of aluminum, 127 mm length, 48 mm height, and weighs 315 g
- Consume shorter heat dissipating time owing to lower metal density
- Better performance in heat dissipating

(1) Intel D2550 CPU soldering onboard
PER321A is based on Mini-ITX industrial motherboard, designed with D2550 processor soldering on board. With processor soldering on board can enhance the resistance of shock and vibration to allow product operates under every possible condition. With processor solder on board would lower resistance and inductance at the connection enhance effective transmission that could guarantee better and more high frequency performance for the system.
(2)High scalability and flexibility
PER321A is an industrial-grade system designed with high scalability and flexibility. Based on different necessity, COM ports can expand from six to ten that allow users to apply more specialized and custom-built devices. 16-bit DIO can meet a variety of industrial applications requirement which including the control of switches, relays, actuators, fans, lights, and motors that enable PER321A to achieve superior performance in industrial control and manufacturing test systems such as factory automation, embedded machine control, and production line verification.
(3)Wide Range DC input
For certain application such like transportation and military always challenge the risk of unstable power that might cause damage to the system. Wide range DC input becomes an indispensable element for those applications. PER321A support 9V~ 24V DC-in to protect system from damage caused by sudden surge or peak voltage. This feature guarantee the system increasing migration path flexible and eliminate redesign of existing power architecture
(4)Three-stage thermal design
Industrial application solutions usually demand to operate in extreme conditions such as high/low temperatures, thermal shock and high humidity. Thus the extended temperature solution becomes extremely significant. PERFECTRON implements three-stage thermal design for PER321A to allow system survive under temperature range -40 to +70°C . The three-stage thermal design is using aluminum heat spreader to absorb heat directly from heat sources, then use heat pipe to transfer heat to aluminum heat sink to surrounding air. The copper heat pipe is the key factor among the whole thermal design. The heat conductivity of heat pipe can reach up to 5000, which is 12 times better than copper heat spreader. With such advanced thermal solution enables PER321A to operate in a torrid environment without processor throttling.

To meet the demands of customer’s extended temperature requirements, the whole thermal solution of INS8335C simultaneously embraces two heat transfer methods, heat conduction and heat convection. For heat conduction, the solution utilizes a copper heat spreader on the bottom layer which directly contact with the processor and chipset. Heat is then transferred to upper aluminum heat sink. Regarding to heat convection, the temperature differences caused by high and low fin design forms a mild airflow that could bring away heat efficiently. Fan can also be an auxiliary by placing an appropriate sized fan on top of the heat sink. Breakdown drawing is provided as below.
