When different "24V DC Cooling Fan" a mix of thermal properties of elements, the best element is mounted on the lower heat capacity of wind, heat a small element mounted upwind. Displays general arrangement of elements, is the heating element is mounted on a large upwind, fever smaller components (C, IC, etc.) installed downwind, so the difference between the heat element will be in the fat component cooling path, the result is an element at a higher temperature at the poor heat resistance. Therefore, "24V DC Cooling Fan" element is preferably arranged press, in fact, the ideal arrangement is still difficult to achieve conductor graphic design. Thermal performance of the same arrangement of heating components: display installed IC (0.3W), the measured value of the temperature rise of LSI (1.5W) when the PCB. "24V DC Cooling Fan" by arrangement, the temperature of the IC's appreciation is 18 ℃ -30 ℃, the LSI temperature rise is 50 ℃. By arrangement, the LSI temperature rise is 40 ℃, the arrangement is even lower than 10 ℃.
