Hi all I havebeen in the plastic injection moulding section for 25 years. We have some moulding machine made from Germany, I don't understand the mfe. install water cool radiator in the electronic control box for better cooling on the electronic, if they select biger power of any electronic component, they will not face heat disperse.thus less maintance problum. Do you agree ? Can any person explain? Thanks
RADIATOR IN THE CONTROL BOX ?

Very likely the watts dissipated by larger components would not be very much less, because the current will be the same, and if SCRs or diodes, the voltage drop will be the same. If the components are FET type devices there could be a benefit to making them bigger. Of course a typical control cabinet has a lot of relays as well, all of which dissipate power. In a warm climate, ambient in a plastics shop can often reach 50C at a machine, and you need cooling to keep the control from cooking. Some people use vortex air coolers, though if you have chilled water for your moulds, why not use it?
All the best

Hi Ian Thanks for your explaination, I notice the japan moulding machine do not need this water cool radiator except a exhaust fan which do not has any problum. I personally feel the japan machine are more friendly user.
