ambient temperature-10℃～40The relative humidity is not greater than the temperature80%Storage environment of ventilated and non corrosive gas
The correct installation and assembly methods are as follows:
1.A cooling plate is installed on one side, and a cooling system installation table is installed on one side
The surface flatness is not too good0.03mmTo remove the card, dirt.
2.The cooling piece contacts well with the radiator and the guide block, and the contact surface must be painted
A thin layer of thermal grease.
3.In the fixed cooling film, the cooling plate must be stressed evenly and carefully cut
Don't over. In order to prevent ceramic fracturing.
The correct conditions for use are as follows:
1.The DC power supply voltage shall not exceed the rated voltage, the power ripple system
2.The current shall not exceed the rated current of the component.
3.When the cooling sheet is working, the reverse voltage must not be reversed instantaneously5branch
After the bell).
4.No water in the cooling film.
5.The humidity should not exceed that of the cooling plate80％。

Calculation method of maximum cooling power
A.1 in the hot end temperature of Th is 27 - 1 Deg. C, temperature difference for T=0, I=Imax,
The maximum cooling power Qcmax (W) is calculated according to formula (1):
