Direct current exported, produce heat melts wlding and solder using low-voltage, high-current arcing, reach the effect of welding.Switch
For power circuit during energy conversion is carried out, heat caused by switching power tube and commutation diode is particularly big, in order to
Ensure that both devices will not cross cause thermal damage, prior art is by installing auxiliary heat dissipation mechanism additional, by switching power tube and rectification
Heat caused by diode is transmitted in auxiliary heat dissipation mechanism, then makes heat Quick diffusing by air blast cooling；Generally the least expensive at present,
Also more satisfactory cooling mechanism is aluminium section bar for heat conduction, coordinates violence blower fan, heat is quickly taken away, to switching power tube and whole
Flow the working environment that diode provides a safety.
Existing direct-current inverter welding machine radiator structure as shown in Fig. 2 including be connected to frame first circuit board 1,
Two circuit boards 2 and heat sink 5, connected on the commutation diode 3 and second circuit board 2 connected on the first circuit board 1
Power switch pipe 4 surface of heat sink 5 is clamped in by clamping plate 10 respectively, because switching power tube 4 and commutation diode 3 are universal
Using iron shell, in order to realize insulation, work(will be switched as insulating barrier 6 by posting high temperature silica gel cloth on the surface of heat sink 5
Rate pipe 4 and commutation diode 3 are isolated, but the thermal resistance of insulating barrier 6 causes the temperature of switching power tube 4 and commutation diode 3
Degree 20 degrees centigrade higher than the temperature of heat sink 5, reduces radiating effect, and electric welding machine continuous operating time is longer, switchs work(
The temperature of rate pipe 4 and commutation diode 3 is higher, and easier to cross cause thermal damage, security is poor, can not meet long-time, high intensity
Job requirement.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of direct-current inverter welding machine radiator structure, can solve existing
Have the radiator structure of direct-current inverter welding machine radiating plate surface patch insulating barrier by switching power tube and commutation diode carry out every
From, cause to reduce radiating effect, can not meet for a long time, the job requirement of high intensity the problem of.
The utility model is achieved through the following technical solutions：
A kind of direct-current inverter welding machine radiator structure, including be connected to the first circuit board of frame, second circuit board and dissipate
Hot plate, the power switch pipe of the iron-clad connected on the commutation diode and second circuit board connected on the first circuit board
Fitting radiating plate surface is set respectively, and the shell of the commutation diode is made of plastics；The heat sink includes spaced
The several piece of arrangement, adjacent two pieces are connected to same insulation board；The commutation diode and power switch pipe are respectively divided into
Array, it is connected to several piece heat sink.
Further scheme of the present utility model is that clamping plate parallel with it, institute are bolted on the heat sink
State commutation diode and power switch pipe is clamped between clamping plate and heat sink respectively.
Further scheme of the present utility model is that the clamping plate is made of a highly heat conductive material.
Further scheme of the present utility model is that the frame is stood including being connected to the first of heat sink front both ends
Post and the second column, positioned at radiating back, upper and lower two crossbeams from the first column to the second column that extend from, described first
Circuit board and second circuit board are bolted to upper and lower two crossbeams respectively.
The utility model compared with prior art the advantages of be：
First, the shell being made of plastics makes commutation diode itself insulate, it is not necessary to which insulating barrier can directly be bonded radiating
Plate surface, heat are quickly transferred to heat sink, effectively reduce the temperature of commutation diode, reduce the possibility that device crosses cause thermal damage
Property, meet long-time, the job requirement of high intensity；Heat sink is divided into several piece, makes array commutation diode and power switch pipe
Mutual electrical isolation, further improves insulation effect, and security is more preferable；
2nd, highly heat-conductive material be made clamping plate make commutation diode and the heat of power switch pipe surface also can Quick diffusing,
Further reduce the possibility that device crosses cause thermal damage.
