Description
Technical field
The utility model belongs to welding technology field, is related to a kind of electric welding machine, more particularly to a kind of IGBT inversion submerged arc weldings
The new mainboard structure of machine.
Background technology
Electric welding machine be the high-temperature electric arc that is produced using positive and negative polarities in instantaneous short circuit come the solder on consumable electrode and
Materials to be welded, makes to be touched the purpose that thing is combined.Electric welding machine uses electric energy, and electric energy moment is converted into heat energy, electric welding machine
It is adapted to work under dry environment, it is not necessary to too many to require, simple to operate because of compact, easy to use, speed,
The advantages of weld seam is solid after welding is widely used in the heavy industry such as ship, automobile, heavy-duty machine, electrical equipment field, due to electric welding
The power of machine is larger, and the power component on its internal mainboard will produce substantial amounts of heat in use, most common at present
Radiating mode is radiated by increasing radiator on power component, then in air-cooled method, due to electric welding machine casing knot
The limitation of structure and in order on mainboard components' placement rationally, distribution of its power component on mainboard is typically more dispersed, and
And each different its caloric value of power component has differences, therefore traditional direct increase the side of radiator on power component
Its radiating effect of formula is unsatisfactory.
The content of the invention
The purpose of this utility model is that there is provided a kind of radiating effect is more preferable for the above-mentioned problems in the prior art
IGBT inversion submerged arc welding machines new mainboard structure.
The purpose of this utility model can be realized by following technical proposal：A kind of Novel main of IGBT inversion submerged arc welding machines
Some triodes are provided with hardened structure, including mainboard and some radiators, described mainboard, the radiating surface of the triode leads to
Cross screw fitted with radiator it is connected, it is characterised in that each described radiator is highly consistent and top is planar structure,
The top of each radiator vertically offers screw and is fixed with by screw between heat sink, each described radiator
One is formed by heat sink.
In above-mentioned new mainboard structure, heat-conducting silicone grease is scribbled between described radiator and heat sink or is sticked has
Heat conductive silica gel band.
In above-mentioned new mainboard structure, the material of the radiator is aluminium alloy.
In above-mentioned new mainboard structure, the material of the heat sink is metallic copper.
Its technique effect of the new mainboard structure of this IGBT inversion submerged arc welding machines is：In order to be carried out to the triode on mainboard
Radiating, is typically to increase radiator on triode at present, and on its every piece mainboard of the electric welding machine of different model triode row
Cloth position and quantity are all different, can only individually be radiated it is difficult to which radiator is formed integrally, but the heating of each triode
Measure and differ and the size of radiator is typically identical, therefore the radiator temperature easily lead to is too high, this mainboard structure
Mainly by the way that the top of radiator is made into planar structure and highly identical so that one piece of radiating can be installed in increase above
Each radiator, as long as opening up the screw corresponding with radiator on heat sink, is connected formula by plate by heat sink, from
And the heat for alloing triode to distribute uniformly is distributed, the triode temperature having will not be caused too high and damaged.
Further, in order that the effect of heat transfer more preferably, is scribbled on its contact surface and led between radiator and heat sink
Hot silicone grease or the heat conductive silica gel band that is sticked.And add area of dissipation of the heat sink equivalent to increase radiator, therefore radiating
More preferably, because the heat-conducting effect of copper is preferable, therefore the material of heat sink uses metallic copper to effect.
Compared with prior art, the new mainboard structure of this IGBT inversion submerged arc welding machines has radiating more uniform and radiating
The more preferable advantage of effect.
Brief description of the drawings
Fig. 1 is the explosive view of this new mainboard structure.
In figure, 1, mainboard；2nd, radiator；3rd, triode；4th, screw；5th, heat sink.
Embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but the utility model is not limited to these embodiments.
As shown in figure 1, the new mainboard structure of this IGBT inversion submerged arc welding machines, including mainboard 1 and some radiators 2, it is main
It is provided with some triodes 3 on plate 1, the radiating surface of triode 3 is fitted connected, each radiator 2 by screw and radiator 2
Highly consistent and top is planar structure, and the top of each radiator 2 vertically offers screw 4 and is fixed with radiating by screw
One is formed by heat sink 5 between plate 5, each radiator 2.
Further describe in detail, heat-conducting silicone grease is scribbled between radiator 2 and heat sink 5 or is sticked heat conductive silica gel band, radiate
The material of device 2 is aluminium alloy, and the material of heat sink 5 is metallic copper.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although more having used the terms such as mainboard 1, radiator 2, triode 3, screw 4, heat sink 5 herein, not
Exclude the possibility using other terms.It is of the present utility model just for the sake of more easily describing and explaining using these terms
