> When stacking, the combined height of the foot pads should meet the minimum height space of 0mm for thermal design. Visual occlusion equipment inside, so that the appearance of fresh, concise and straight feeling.

> The system adopts draft design. The system module is a vertical module, consisting of four RE modules and one power supply module. The system power supply is located behind the backplane. To avoid structural interference, the RE module is made into a special-shaped board.

> Strengthen the key parts of the function, easy to identify, easy to use, enhance the device function indicator.

>K7 uses 60mm*60mm aluminum welded radiator, radiator base thickness is 3mm, fin height is 32mm, fin thickness is 0.3mm, tooth spacing is 3mm.

> When the ambient temperature is 50 ° C and the fan spins at full speed and the fan spins at 30% speed at 25 ° C, the components meet the heat dissipation requirements. To reduce noise, it is recommended that the system adopt target speed control scheme.

> The air inlet is located at the bottom and side of the tester chassis. To improve heat dissipation, some heat dissipation holes are also opened at the lower side of the panel of each module. The fan module is located at the air outlet in the rear upper part of the tester chassis and uses five 8038 fans (9GA0812P1H61).
