First of all, immersion cooling can be seen from the name. It is a kind of heat dissipation method that all electronic components are immersed in liquid and heat is quickly taken away through the flow of liquid. Because all electronic components are immersed in the refrigerant medium, this heat dissipation method is all-round and has higher heat dissipation efficiency.
Secondly, this way of heat dissipation depends more on the physical and chemical properties and structural design of the refrigerant itself, so if you can find an excellent heat conducting liquid, the cost and energy consumption of this way of heat dissipation can be greatly reduced. At present, 3M fluorinated liquid and Yang Lanbo thermal conductive liquid have done better in the fields of two-phase heat dissipation and single heat dissipation respectively. Yang Lan, in particular, is a rising star in the field of heat dissipation in the past two years. It is said that immersion liquid cooling technology has been used in PC, which is really rare.
In addition to excellent cooling effect, this cooling method has many other benefits, such as:
1) Single-phase heat dissipation does not involve the change of liquid state, so it can greatly reduce the size of equipment while improving heat dissipation efficiency. If it is in the industrial field, it can greatly improve the space utilization.
2) In the industrial field, air cooling is still widely used at present, but the energy consumption of air cooling is large, the loss is serious and the cost is high; In contrast, immersion cooling can greatly reduce energy consumption loss and shorten the payback period.
3) Soaking hardware in non-corrosive liquid for a long time can slow down the wear and tear of hardware, and relatively improve its service life and the value of secondary recycling.
In a word, the advantages of submerged liquid cooling are very obvious, which is why it is called "the third generation heat dissipation technology".
