In the 1950s, with the rapid development of semiconductor materials, thermoelectric coolers gradually moved from the laboratory to engineering practice, and applied in the fields of national defense, industry, agriculture, medical care and daily life, and were able to be used as air conditioners for nuclear submarines. Small enough to be used to cool the infrared detector's probe, so the thermoelectric cooler is often referred to as a semiconductor cooler.
Semiconductor refrigeration is simple, safe, green, and has rapid cooling.It also occupies a lot of space in the field of heat dissipation, and the thermal inertia of semiconductor refrigerating sheets is very small.The cooling and heating time is very fast. When the hot end is well cooled and the cold end is unloaded, the power can be reached for less than one minute, and the cooling piece can reach the maximum temperature difference.After the semiconductor chip is energized, there will be two working faces, and one side will be heated while cooling. When used in the field of heat dissipation, the cold water brought by the cold end can quickly cool down the equipment that needs heat dissipation.
Some large equipment or precision equipment are more demanding on temperature and require precise temperature control. Semiconductors can meet such needs, which requires semiconductors to continue to work stably. If you want to continue to get low-temperature water, you need to accelerate the heat transfer, that is, the heat at the hot end will increase. When the heat at the hot end is not released in time, the cooling at the cold end will be weakened. At this time, it is necessary to heat the heat to the hot end, and the heat sink has fin-type heat dissipation and air-cooling heat dissipation. These two methods of heat dissipation can be used in the case of low power. But when the power is very large, it is a little powerless. So how to solve it?
At present, more water cooling is applied, which can meet such requirements. The advantages of water cooling and heat dissipation have been familiar to many friends. It can quickly dissipate heat and also have the characteristics of quietness and greenness. The heat of the semiconductor hot end is quickly dissipated, and the cooling efficiency of the cold end is improved. The cold end can continue to provide low temperatures, which enhances the efficiency of the work.
