The hardness, thickness and thermal conductivity of the heat transfer gasket, the relationship between these three is a topic that is not open, and there is a chewing head like a three-corrush love relationship.
First, when the thermally conductive gasket is pasted on a heat transfer member, the lower the hardness of the heat transfer gasket, the more soft, the more the gap is filled, and the air is discharged, so that the heat transfer gasket is in contact with the heat generating member. The contact area is larger. Therefore, the heat from the heat transfer member passes through the heat transfer gasket will be faster and the heat dissipation effect is better because the effective contact area is increased.
Second, the relationship between the thickness of the thermally conductive gasket and the heat conduction effect. When the thermally conductive gasket is adhered to the heat generating member, the thicker the thickness of the heat transfer gasket, increase the transmission distance, heat from the heat transfer member, that is, the longer from the one-size side of the heat-conductive gasket to the other side, so hot The slower it is passed. In contrast, the thinner thickness of the thermally conductive gasket is, the shorter the heat from one side to the other side, the better the heat conduction effect. The thicker the thermal gasket, there is side effects, and simply considering the material cost, it is not only a thinner thermal gasket, but also more expensive, because the thickness is thick, the required raw materials are more, more expensive .
Our company recommends that when choosing a thermal gasket, if the gap is 1mm, it should be selected 1.5-2.0mm thermal gasket. It must take into account the compression of the thermal gasket, can't be too thick, and the heat is increased. Resistance, thin gap fill dissatisfaction, high hardness is not much considered too much consider compression. Therefore, according to the characteristics and gaps of their own products, select the hardness and thickness of the appropriate thermal gasket, must only choose the right, not expensive, our company is doing practical things, not talking.
