Technical field
The utility model belongs to electric welding machine circuit engineering field, refers in particular to a kind of optimization radiator structure of electric welding machine circuit.
Background technology
As everyone knows; Electric welding machine is big owing to the electric current that needs usefulness in welding process, voltage is high; Used more high performance components in its control circuit, for example IGBT pipe, rectifying and wave-filtering electric capacity, inductor, transformer etc., these high performance components are generally according to circuit layout; One end of circuit board is installed radiator fan; Facing to the blowing of the high performance components on circuit board heat radiation, its weak point is: do not consider the trend of high performance components position relation, hiding relation and airflow channel each other during owing to design circuit, cause the near good heat dissipation of discrete heat fan; Apart from radiator fan far away or to be blocked the heat radiation in air port by the tall and big high performance components in front just poor, even the fault that high performance components occurs burning out takes place.
Summary of the invention
The purpose of the utility model provides a kind of optimization radiator structure of electric welding machine circuit.
The purpose of the utility model is achieved in that
The optimization radiator structure of electric welding machine circuit; Installed in front between the circuit board has radiator fan up and down; Be connected with the component that needs heat radiation in the electric welding machine circuit on the face that circuit board is relative up and down respectively; The component that needs heat radiation forms thermal dissipating path from the front side to rear side on circuit board, inwardly and be horizontally disposed with, electric capacity sets in a row from the front side to rear side the opening of the fin that is arranged in parallel that needs to connect on the component of heat radiation on circuit board.
An above-mentioned circuit board is provided with flange-cooled IGBT pipe and filter capacitor; The IGBT pipe is in the outer of this circuit board and is provided with outwardly; Filter capacitor becomes the yi word pattern setting from the front side to rear side; The main transformer branch of output rectifier on another circuit board and split-type structural is located at the left and right sides of circuit board, and the main transformer of split-type structural becomes the yi word pattern setting from the front side to rear side.
The utility model is compared the outstanding and beneficial technical effects of prior art:
1, the utility model needs the layout high performance components according to heat radiation earlier; Other electric elements of layout again; Taken into full account the trend of all around position relation, hiding relation and the airflow channel of high performance components, make high performance components radiating condition be improved significantly, low, the high arcing time factor of fault rate is high; Under the situation that does not increase air quantity; The high arcing time factor of welding machine reaches more than 60%, compares 35% of prior art and improves 25%, makes the performance of welding machine be greatly improved.
2, the utility model is simple in structure, and electric elements are rationally distributed, and production cost and prior art are close, suits on various types of electric welding machines, to use.
