Relevant Requirements For The Use Environment Of Electronic Heat Sink

Electronic heat sink is a kind of radiator emerging in recent years. Electronic heat sink is a product that combines heat pipe technology and radiator technology. Its heat dissipation efficiency is extremely high. The specific use environment requirements are as follows:

1. When used in high-voltage or higher-voltage devices, it must ensure the above water quality requirements or higher water quality requirements;

2. There should be certain requirements on the water quality of the cooling water, the inlet water temperature is not higher than 35℃, and the water flow rate is 4-8L/min;The resistivity of circulating water should not be lower than 2.5Ki2, and the PH value should be between 6-9;

3. Water cooling requires water cooling devices, water electronic radiators, cold heat sink, and indispensable water circulation systems.

4. When the water-cooled heat sink is working, special attention should be paid to preventing water leakage, blocking and condensation.

5. When installing the air-cooled radiator, the air temperature at the inlet of the electronic heat sink should not be higher than 400C, and the wind speed at the inlet side should be 4-6mls; According to load requirements and fan capacity, check the relationship curve of radiator thermal resistance, flow resistance and wind speed, and comprehensively consider the two parameters of electronic heat sink thermal resistance and wind resistance. When the heat is transferred to the top of the electronic radiator, it needs to be dissipated to the surrounding environment as soon as possible. For the air-cooled electronic radiator, the electronic radiator needs to exchange heat with the surrounding air. At this time, the heat is transferred between two different media, and the formula followed by the electronic heat sink is Q=α X A X ΔT.

When the heat is transferred to the air, the temperature of the air in contact with the heat sink will rise rapidly. At this time, the hot air should try to take away the heat with the surrounding cold air through heat exchange methods such as convection. For air-cooled heat sinks , The most important method is to increase the speed of air flow and use a fan to achieve forced convection.

Generally, the natural heat dissipation method is used for electronic heat sinks, and the use environment should be well ventilated, free of dust and floating objects. The drag objects of this type of inverter are mostly household air conditioners, CNC machine tools, etc., with low power and relatively good use environment. The industry reports that heat pipe heat sink have good performance and are worthy of promotion.
