Configuration optimization type converter

The application discloses configuration optimization type converter extends through the bottom level with the heatsink and forms the bottom plate to being the casing setting and having the outer bell -type that can wholly hold the outside accommodation space of converter main part, rely on the heatsink bottom plate to accomplish the assembly of component, owing to do not have sheltering from of shell among the assembling process, be convenient for observe, the convenient assembling of component, accurate and quick can carry out preliminary test to the product rapidly after the assembly is accomplished, and the installation and measuring precision is high, treat preliminary test accomplish after again the cover establish the casing, effectively guarantee the product yields, simultaneously, owing to adopt outer bell -type shell structure, effectively reduce shell mould quantity, reduce the cost of manufacture, and the casing mounting means is simple swift, the dismouting maintenance of being convenient for further reduces the maintenance cost in later stage.
