Shengyida is the leading aluminum heat sink manufacturer, offers custom aluminum heat sinks. Many consumers do not know the heat dissipation method of heat sinks, Shengyida will tell you today.
heat sink cooling method
When the air is cooled to below the dew point temperature, the water vapor in the air will condense into water. Remove the condensed water and reheat it to obtain low-humidity air≌The cooling source of the air can use the refrigerant of the freezer, ice water or brine.
heat sink compression cooling method
Compress the air and then cool it, and the water vapor in the air will condense into water. Remove the condensed water and reheat it to obtain low-humidity air≌The moisture in the air is expressed by the following formula:
heat sink adsorbent batch type (tower type)
Use solid adsorbent (such as silica gel, sieve, activated aluminum vaporization, zeolite, etc.) as a fixed layer and fill it in the tower (cylinder). Use two or more towers. One tower is used to adsorb air moisture, and the other One tower is regenerated. After a certain period of time, the tower is converted and the air circuit is changed so that the moisture absorption and regeneration functions are interchanged so that intermittent heat dissipation air can be generated.
heat sink liquid type absorbent
Using lithium chloride solution as the absorbent, the main system is composed of a custom heat sink, a regenerator, and a circulating pump. When the air contacts the sprayed absorbing liquid in the heat sink, the water in the air is absorbed by the solution to dissipate heat, and then The cooling coil cools the condensation and absorption heat due to absorption. The solution that has absorbed the water is pumped to the regenerator by the solution circulation and comes into contact with the regeneration air heated by the heating coil. The water in the solution evaporates and is discharged outside with the regeneration air, so the concentration of the solution in the regenerator increases, and again It is sent to the aluminum heat sink in Beijing Sao Paulo by the circulating pump.
The heat sink turns into a dry honeycomb turntable
A cylindrical turntable is formed with a honeycomb structure, and then a heat-dissipating turntable is made by attaching moisture absorbent (lithium chloride, silica gel, zeolite, etc.) raw materials by a special crystal processing method. The heat dissipation turntable rotates in a box partitioned into a heat dissipation zone and a regeneration zone. The air used for heat dissipation passes through the heat dissipation area, and the moisture in the air is absorbed by the turntable to obtain dry air. The heat dissipation area after absorbing water is moved to the regeneration area by the rotation of the turntable, and the regenerated heating air takes out the water in the turntable and discharges it to the outdoors. The turntable rotates to the heat dissipation area after the water is released from the regeneration area, so that heat dissipation and regeneration are continuously carried out at the same time. Stable heat dissipation air can be obtained.
