1) From the "24V DC Cooling Fan" cooling effect, the cooling plate is made of a square or disc-shaped ideal. If restricted processing conditions or the installation position must be made rectangular, length, and width of not more than 2: 1.
2) "24V DC Cooling Fan" radiating plate in contact with the surface of the device should be kept clean, flat (convex and concave contact surface distance is less than 0.05mm), no warping and corrosion. To the heat radiating plate is secured to the device, to ensure both a close fit. Try installing the device at the center of symmetry of the cooling plate. Cooling board should be placed vertically, flat affect "24V DC Cooling Fan" cooling effect. To improve heat dissipation, the best coat of thermal grease on the contact surface.
