The following question L shows that the heat dissipation structure of the power supply basically exists. :: The power supply la is arranged in an upright position, and the heat transfer moves slowly, making the flow path of the gas quite long. The highest heat value accumulates at the top, which causes the electronic components 11 a in this area to be burnt and damaged due to high temperature. The direction of the heat transfer block 12a and the gas flow direction are equal to each other, which will hinder the flowing gas, slow down the speed of the gas, and reduce the heat transfer effect of natural air convection. ; IL motion Bayi u Hai power supply state 1a to match the flat display device? > For soil type I, it is necessary to reduce the height of the heat conducting block 12a and reduce the heat dissipation volume = thin. Its heat dissipation efficiency is greatly reduced.
