Embodiment

Below in conjunction with accompanying drawing and better embodiment, the utility model is further described:

Refer to Fig. 1 to Fig. 6, the utility model relates to a kind of amorphous alloy transformer, and its better embodiment comprises fuel tank 10, core assembly 40, coil block 60 and three radiators 20.

This core assembly 40 and this coil block 60 are all installed in this fuel tank 10.The cross section of this fuel tank 10 is roughly equilateral triangle, and it is surrounded by three sidewalls, and three radiators 20 are installed on respectively on three sidewalls of this fuel tank.

Each radiator 20 comprises pedestal 23, some radiating parts 22, heat-transfer pipe 24 and evaporation box 25.

Some radiating parts 22 extend upward and form from the end face of this pedestal 23, and the width of each radiating part 22 dwindles from bottom to top gradually, and the longitudinal profile of each radiating part 22 is isosceles triangle, and this can make the heat-conducting effect of radiating part 22 better.
