After analyzing and repairing the machine for a period of time, the temperature inside the chassis rises, because the heat dissipation is slow, if there are components with poor thermal stability in the machine, it will inevitably lead to failure. When the back cover of the machine is opened, the failure does not occur, and it is concluded that there is a component with poor thermal stability in the circuit. If the method of observing the waveform voltage of the observation signal is not effective, and the substitution method is too time-consuming, the heating element can be used to quickly detect the faulty component. According to the user's report, the fault occurred for nearly one month, and the initial machine can still work for more than one hour. Now it can't be watched in less than half an hour. Analysis of the fault caused by the thermal stability of the field scanning circuit, the use of alcohol cotton ball to the field scan integrated block heat dissipation failed to work. Then, the peripheral components related to the field sync field oscillation and the like are radiated one by one. When the cotton ball is placed on the Bayer oscillation time constant capacitance, the fault disappears. For further confirmation. Remove the cotton ball to make the fault come back, and use a fan to dissipate heat on the board for a large area to make the fault disappear.
Prandt number of thermal conductivity in automotive heat exchangers such as water radiator oil radiator transmission oil radiator, supercharged intercooled engine intercooler, and heater condenser evaporator for improving the internal temperature of the vehicle, etc. Among them, the water radiator is a large part in terms of volume and weight. Therefore, the high-performance, high-compact and lightweight water radiator is obviously important for solving the heat dissipation problem of the new-generation main battle tank and the layout of the power cabin.
