Some people find that even if the heat dissipation material is filled, the heat dissipation effect is still not ideal. Is the heat dissipation effect of the heat sink not ideal because of the サーマルマテリアル?
In fact, the heat dissipation effect of the radiator is not ideal, and the problem of the サーマルマテリアル cannot be directly mentioned. There are many reasons for this, and there are probably two points that appear more frequently.
First of all, as a kind of heat-conducting medium material, the サーマルマテリアル plays the role of auxiliary heat transfer, can reduce the contact thermal resistance and improve the heat transfer efficiency, but the main heat dissipation is the radiator, so if the power of the radiator does not meet the requirements , No matter how good the thermal conductivity of the サーマルマテリアル is.
Then, the thermal conductive material is not operated in accordance with the normal use specifications. For example, the bonding surface is not cleaned before filling, no silicon completely covers the bonding surface, and the thermal conductive material is too thick and other factors will affect its heat dissipation effect.
There are many reasons why the radiator fails to achieve the expected effect. It cannot be considered as a サーマルマテリアル problem unilaterally. It is necessary to consider the factors affecting its heat dissipation efficiency in many aspects to optimize it.
