Any equipment in operation will produce a certain quantity of heat, just some equipment heat low no installation radiator, heat is very big, but some equipment run time will have to install the radiator, so we often use the fast thyristor
module need to install the radiator?
Take a look at below.
Fast thyristor module, when an electric current passes through, can produce a certain pressure drop, while the existence of the pressure drop will produce certain power consumption, electric current, the greater the power, the greater the heat.
If you don't put these quantity of heat quickly melted away, will seize the thyristor chip problem.
Therefore requires the use of fast thyristor module, be sure to install the radiator.
The stand or fall of cooling conditions, is fast thyristor module can be an important factor of safety work.
Good heat dissipation conditions can not only ensure fast thyristor module reliable work, to prevent overheating module burned, but also can improve the ability of fast thyristor module output current.
Suggest users in the use of large current specifications fast thyristor module as far as possible choose module with overheating protection function.
Fast thyristor module is, of course, even with overheating protection function, and the radiator and fan is also indispensable.
In use, when the cooling conditions do not conform to the specified requirements, such as room temperature for more than 40 ℃, the export of forced air cooling wind speed is less than 6 m/s, etc. , the rated current of the fast thyristor module should immediately reduce use, otherwise the module will be damaged due to the chip junction temperature exceed allowable values.
For example, air-cooled module should be adopted according to the rules and using the cold, the current rating should be reduced to the original value of 30 ~ 40 [
And vice versa if instead of using water, the current rating can increase 30 ~ 40 [
