mprove the heat release in LED display
In practice, improve the heat dissipation of LED display, not only effectively improve the efficiency of the heat release of LED display, also can save electricity, is more advantageous to increase the effectiveness of the service life of the LED display.
1, fan cooling, lamp shell internal reinforced with long life high efficiency fan cooling, more commonly used method of this method is low cost, good effect.
2, the use of aluminum radiator fins, this is the most common way of heat dissipation, use aluminum radiator fins as a part of the shell to increase the cooling area.
3, air, fluid mechanics, the use of lamp shell shape, make air convection, this is the lowest cost to strengthen the cooling method.
4, surface radiation heat treatment, lamp shell surface radiation heat treatment, is relatively simple daub radiation to paint, can be taken away from the lamp shell surface heat radiation way.
5, heat conduction heat integration - the use of high thermal conductive ceramics, lamp shell heat dissipation is the purpose of reduce the working temperature of hd display led chip, due to the led chip we often metal thermal conductivity, thermal expansion coefficient and material expansion coefficient difference is very big, the led chip can not be directly welding, to avoid the high and low temperature thermal stress damage led display chip.
6, heat pipe cooling, the use of heat pipe technology, heat by LED display chip guide to shell the cooling fins.
7, thermal conductive plastic shell, when the plastic shell injection molding filling thermal conductive materials, so as to increase plastic shell heat conduction and heat capacity.
Visible LED display the cooling technology of mature and progress will be conducive to its saving, environmental protection concept. LED electronic display manufacturers on the LED display production, various method to improve the heat release of LED display. Heat according to the power size and the use place, will have different considerations.
