LED display due to the density of pixels itself heat is large, long-term outdoor use, the internal temperature is bound to gradually climb, especially the area is relatively large [outdoor LED display] heat dissipation becomes a problem that must be paid attention to, LED display heat indirectly affects the service life of LED display, LED display, LED display, LED display. It even directly affects the normal use and safety of the LED display. How to dissipate heat has also become a problem that the display must consider.

The heat exchange area between heating electronic parts and cold air, and the temperature difference between heating electronic parts and cold air directly affect the heat dissipation effect. This involves the design of the air volume entering the led display box and the design of the air duct. In the design of ventilation pipes, try to use straight pipes to transport air, and avoid using sharply turning and bending pipes. Ventilation ducts should avoid sudden expansion or contraction. The expansion Angle should not exceed 20o, and the contraction cone Angle should not exceed 60o. Ventilation ducts should be sealed as far as possible, and all lapping should follow the direction of flow.

Box design precautions The air intake should be set on the lower side of the box, but not too low, so as to avoid dirt and water entering the box installed on the ground.

Exhaust holes should be arranged near the upper side of the box.
The air should be circulated from the bottom to the top of the box, and special intake or exhaust holes should be used.
The cooling air should be allowed to flow through the heating electronic parts, while preventing short circuit of the air flow.
A filter should be set at the air inlet and air outlet to prevent debris from entering the box.
It should be designed so that natural convection contributes to forced convection
Ensure that the air inlet is far away from the exhaust port. Avoid reusing cooling air.
Ensure that the direction of the radiator groove is parallel to the wind direction, and the radiator groove cannot block the wind path.
Fans are installed in the system, and due to structural limitations, the air intake and air outlet are often blocked by various types, and their performance curves will change. According to practical experience, it is best to have a distance of 40mm between the inlet and outlet of the fan and the barrier, and if there is space limitation, it should also be at least 20mm.

[Outdoor LED display] maintenance program, one should do a good job of heat dissipation measures, the second is to avoid improper operation in use. It is recommended to configure fans or air conditioners to enhance heat dissipation.
