At present, the development of aluminum radiators on the market is booming, which needs to be attributed to the high efficiency of aluminum radiators. How to achieve high-efficiency work of profile radiators?

The first thing we need to know is the profile radiator, which is an important parameter to ensure that the thermal grease is in a solid or liquid state. If the temperature is too high, the electronic radiator will be wholesaled, and the thermal grease will become liquid due to the decrease in viscosity; if the temperature is too low, the electronic radiator will become solid due to the increase in viscosity, which is not conducive to heat dissipation. The working temperature of thermal grease is generally between -50°C and 220°C. Generally, there is no need to worry about the working temperature of thermal grease. After all, it is difficult to make the CPU temperature exceed this range by conventional means, unless you plan to use liquid nitrogen for cooling-thermal grease will mostly lose its effect at that temperature.

The thermal conductivity system of thermal grease is much smaller than the commonly used radiator materials. In the current general specifications, which is better for the resistance radiator, the thermal conductivity of thermal grease is required to be 113W/MK, which is different from the 401W/mk of copper, but it is still much higher than that of air. You can also see how important it is that the bottom of the radiator is smooth. Some manufacturers claim that the radiator with a matte bottom only needs to be filled with thermal grease, which does not affect the heat dissipation capacity, which is shameless. Viscosity is the consistency of hot silicone grease. Generally speaking, the viscosity of thermal grease is around 68.

The coefficient of thermal resistance represents the blocking effect of an object on heat conduction. The concept of thermal resistance is very similar to resistance, and its unit is similar to it (℃/W), that is, when the continuous heat transfer power of an object is 1W, the temperature difference between the two ends of the heat conduction path. Obviously, the lower the thermal resistance, the better, because under the same ambient temperature and heat conduction power, the lower the thermal resistance, the lower the temperature of the heated object. The size of the thermal resistance is related to the material used in the thermal grease.

Dielectric constant: Compared with some CPUs without metal top cover, the dielectric constant is a very important parameter, which is related to whether the computer has a short circuit. The dielectric constant of thermal grease for mainstream heat sinks is greater than 5.1. Ordinary thermal conductive silicone grease is made of materials with good insulating properties and manufactured by the resistance radiator company, but there are also some special silicone greases (such as silver-containing silicone grease, etc.) that may have a certain degree of electrical conductivity. Of course, the CPU is the core of the installation and maintenance of heat conduction on a metal roof, so there is no need to worry about short circuits caused by the overflow of thermal grease, but be careful when applying it, and do not mistake it for other places with thermal grease, such as the motherboard.

Be careful when using thermal grease. The most important thing in applying thermal grease is uniformity. The inverter radiator can cover the CPU core. There is absolutely no need to apply too much or even a thick layer, which will affect the profile radiator. It needs to be clear that the so-called high thermal conductivity of thermal grease is only compared with air, and the price of inverter radiators is compared with materials such as copper or aluminum for profile radiators. In addition, most common thermal grease will "dry" or "harden" after being used for one year or more. This refers to the radiator manufacturer, which has a great influence on the heat dissipation effect. Therefore, in order to maintain the long-term stable operation of the system, it is necessary to clean and reapply the silicone grease regularly.
