Points to note when choosing thermally conductive products

Modern people are inseparable from electronic products, from bulky desktop computers to ultra-thin dual-in-one notebooks, from brick-like mobile phones to the new iphones, from players on their shoulders to such as Chip-sized iPods, technological developments have made electronic products increasingly lighter and more efficient, but have people here realized that the smaller the electronic products, the higher the heat dissipation they require, why? Below I give a small example.

Almost most families now have computers. If anyone who has assembled a computer knows that the hardware of the computer is not large, but the remaining space inside the host is large, mainly because the computer generates a lot of heat when the computer runs, and the heat passes through The radiator is distributed through the internal space, and the place where the host generally generates more heat is the central processing unit (CPU), so there will be a cooling fan on it. If the heat sink cannot conduct heat efficiently, the computer may be damaged due to high temperature, so the heat dissipation effect of the heat sink becomes extra important.

At this time, a thermally conductive material is needed. Generally, the thermally conductive material is used between the heat source and the heat sink. As a heat conduction medium, the heat of the heat source can effectively conduct the heat sink. When choosing thermal conductive materials, people will consider the thermal conductivity and price as the main indicators, but there are other parameters that are not paid attention to. Here, the editor will tell you about the main points when choosing thermal conductive products.

First, the thermal conductivity is the fundamental parameter of all thermally conductive materials. The thermal conductivity is academically interpreted as referring to a 1m thick material under stable heat transfer conditions. The temperature difference between the two sides of the surface is 1 degree (K, ℃) at a certain time. Inside, the heat transferred through an area of ​​1 square meter is expressed in watts / meter · degree. General customers will have clear thermal conductivity requirements. Here is a reminder: the big factor in determining the price of thermal conductivity material is its thermal conductivity. Customers should consider their own suitable thermal conductivity when choosing. Do not think that the higher the coefficient, the more it is good.

Secondly, the thickness, as the gap filled between the heat source and the heat sink, determines that its thickness will not be particularly thick, but it will not be particularly thin, as thin as the cicada wings will wear on touch, too thick and affect the thermal conductivity, so The height between the gaps must be measured in advance to avoid unnecessary factors.

Then the use environment of the product, the current thermal conductive material is mainly based on silicone resin, there will be precipitation of silane molecules under the condition of continuous high temperature, some equipment is sensitive to silicon, or solid sheets are required for product installation, in operation When fluid paste is needed, the customer can tell the product manager the specific situation of the product and let him select the appropriate product according to the situation.

At present, when selecting the thermal conductive materials, we can conduct detailed consultation with the thermal material manufacturers. Sheen company serves customers and brings higher benefits to customers.
