Summary of the invention
Based on this, the utility model is to overcome the defect of prior art, and a kind of internal structure compactness is provided, and is beneficial to the welding machine case that contains pfc circuit that shortens self length.
Its technical scheme is as follows:
A welding machine case that contains pfc circuit, comprises base plate, is fixed on the radiator on described base plate, and is fixed on the master control borad on described base plate, is fixed with pfc circuit plate on described radiator, and described pfc circuit plate is electrically connected with described master control borad.
Below further technical scheme is described:
Preferably, on described radiator, be fixed with heat-conducting plate, described pfc circuit plate is fixed on described heat-conducting plate.
Preferably, described heat-conducting plate is aluminium base.
Preferably, described pfc circuit plate is fixed on the upper surface of described radiator.
Preferably, described radiator includes the first radiator setting up and down and the second radiator, and described pfc circuit plate is fixed on described the first radiator.
Preferably, one end of described base plate is vertically fixed with rear plate, the other end is fixed with header board, cooling fan is fixed on described base plate, described the first radiator and described the second radiator are positioned at the air side of described cooling fan, and the both sides of the first radiator and the second radiator are fixed with respectively master control borad and deep bead.
Preferably, described base plate, described rear plate and/or described header board are provided with multiple air vents.
Below principle, the effect etc. of aforementioned techniques scheme are described:
1, pfc circuit plate is installed on described radiator, dispels the heat directly to pfc circuit plate by radiator, improved the heat dispersion of pfc circuit plate, and shortened the length of welding machine case, improve the cyclic duration factor of welding machine, and reduced the cost of welding machine.
2, by heat-conducting plate is set, the thermal diffusivity of pfc circuit plate is strengthened processing, further strengthen the thermal diffusivity of pfc circuit plate.
3, master control borad, deep bead and the first radiator, the second radiator have formed air channel, and pfc circuit plate and air channel isolation are arranged, and the thermal diffusivity of pfc circuit plate, directly by radiator heat-dissipation, makes dust and moisture be difficult for components and parts to corrode; On the other hand, expanded the space in air channel, layout is more reasonable, makes the radiating effect of welding machine better, and the reliability of welding machine complete machine is better, and is conducive to extend the life-span of welding machine.
