Boxed SMPS Design Cooling Examples

SMPS circuits usually open type cooling is very important in power supplies adapter or amateur field studies, so not a problem because it is spacious area has a large fleshy cooling fan deny use to make air circulation and so on. SMPS circuit for closed-type, but has a very fine calculations

Below of various brands closed type SMPS adapters circuit photos available forces according to their quality, various methods used design for can give an idea of my many models I have seen in the cooler box completely to be associated with plastic box theme very high so that the interior temperature drop is possible and cooling the space used for slightly smaller than the box-like box inside the box

Delta Electronics companies engaged in the production of laptop power amp 19 volt 3:42 Kanagi quality is not quite a standard flyback SMPS design primers in the output diode and MOSFETs are cooled independently

Ataba brand gradually adjustment SMPS 15v, 16v, 19v, 22v, 24v voltages stage there on the box 24volt 3 ​​amp other voltage for the 3.5 amp power can give specified circuit six completely with coolant coated side of the output diode and primers located in MOSFETs for mounting portions are additional the upper section transformer to cool the aluminum mixture of copper plates available I be tuned on the transformer overheated causing further 220 volts at input 3 amp diodes (four diode bridges) in pairs small plates with chilled

Olympus 24 volts 2.5 amps SMPS design has a high-quality copper plates used for cooling large in size, can operate at full load for a long time I guess
