± 3 DEG C even higher.Partial Power is smaller, and the few device of calorific value has the phenomenon that actual temperature is well below target temperature.
Scheme also is using liquid as cooling media, Ru Shui, oil, also has certain drawbacks using such scheme.Water
Rate of heat exchange is higher, when device needs cooling, soon the temperature of device can be taken away, under this can lead to temperature soon
Drop, the fluctuation range of temperature can be very big.The problem of the use of oil being not in then temperature fluctuation, oily use is to follow under normal circumstances
Ring, when oily by high temperature, after circulation line long-term work, the quality of oil can be caused to change, generate precipitation or have
Malicious harmful substance.There is the shortcomings that a larger during using liquid as cooling media, be exactly troublesome maintenance, have risk of leakage, operation
It is inconvenient.When liquid leakage occurs, the damage of service life property can be caused, and be difficult to prevent to device, circuit or machinery.In device
During part clamping to aging board, need aging board being detached from normal operation position, at this moment fluid pipeline can be pullled, at this time
Have larger damage risk.
