Description
Technical field
The utility model relates to a kind of welding supply that metal is fused, and especially a kind of family that can be applicable to uses novel miniature arc welder.
Background technology
The manufacturing of the source of welding current has 100 years of development history, enter after the sixties in 20th century, the appearance in succession of silicon rectifier cell, high power transistor (GTR), FET (MOSFET), igbt devices such as (IGBT), the development of integrated circuit technique and control technology, for the development of electronic welding power supply provides more wide space, wherein the most noticeable is inversion welding source.Inversion welding source is than long-pending little, in light weight, the energy-conservation province of traditional industry frequency welding body material, and control performance is good, and dynamic response is fast, is easy to realize the real-time control of welding process, has very big potential advantages on performance.But, along with people to the constantly miniature requirement of arc welder volume, make arc welder with existing arrangement and further dwindle and reduce volume, have sizable difficulty, and also there is deficiency in existing arc welder aspect heat radiation.In view of the foregoing, be badly in need of the interior arrangement structure of existing miniature arc welder is improved adjustment.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above in the prior art, and a kind of novel miniature arc welder is provided.
The utility model is achieved in that a kind of novel miniature arc welder, comprise: cabinet, IGBT radiator in the cabinet, rectification radiator (power rectifier radiator and output rectification radiator) and amorphous main transformer, it is characterized in that: described cabinet left end has air inlet, in the air inlet place one blower fan is arranged at cabinet inside, there are two circuit boards (first circuit board and second circuit board) parallel and installed surface is outside in the stage casing of cabinet, between first circuit board and second circuit board at a certain distance, form a vent passages, there is described IGBT radiator in left side on the first circuit board installed surface, there is described power rectifier radiator on its right side, described output rectification radiator is arranged on the second circuit board installed surface, the right-hand member of cabinet inside has described amorphous main transformer, has air outlet at the right-hand member of cabinet.
Described air outlet is opened respectively on the side plate of cabinet right-hand member, front and rear panel and base plate.
Described air inlet is opened on the side plate of cabinet left end.
Described first circuit board on end, the IGBT radiator on it has 4, is arranged in order up and down.
The utility model has the advantages that simple in structurely, science design radiator structure reaches that system stability is reliable, volume is little, light weight, purpose that energy consumption is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cutaway view of the A-A in the utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
The specific embodiment
Among the figure, a kind of novel miniature arc welder, comprise: cabinet 1, IGBT radiator 7 in the cabinet, rectification radiator (power rectifier radiator 8 and output rectification radiator 6) and amorphous main transformer 9, it is characterized in that: described cabinet 1 left end has air inlet 2, one blower fan 3 is arranged in the air inlet place in cabinet 1 inside, there are two circuit boards (first circuit board 4 and second circuit board 5) parallel and installed surface is outside in the stage casing of cabinet 1, between first circuit board 4 and second circuit board 5 at a certain distance, form a vent passages 11, there is described IGBT radiator 7 in left side on first circuit board 4 installed surfaces, there is described power rectifier radiator 8 on its right side, described output rectification radiator 6 is arranged on second circuit board 5 installed surfaces, because the rectification radiator is in the left and right sides of the bigger machine mid portion of space, the heat that produces during work can be taken away by wind effectively and can be to space radiation all around, propagate to the machine external space by the cabinet wall, thereby reach the purpose that rectification is dispelled the heat.The right-hand member of cabinet inside has described amorphous main transformer, has air outlet 10 at the right-hand member of cabinet 1.
Described air outlet is opened respectively on the side plate of cabinet right-hand member, front and rear panel and base plate.
Described air inlet is opened on the side plate of cabinet left end.
Described first circuit board on end, the IGBT radiator on it has 4, is arranged in order up and down.This design both can guarantee the effective insulation between each IBGT device, can make unlikely the gathering of heat that IGBT when work produce again and was taken away fast by cold wind.Simultaneously, the part heat radiation passes to the space for the machine wall fast, reaches good heat-radiation effect.
During use, by blower fan air outside is sucked from air inlet, flow to the center-aisle that separates by two circuit boards, after directly cold air is guided into the amorphous main transformer of air channel afterbody, the heat that produces during main transformer work is taken away by wind on the one hand, radiation passes in the air for the cabinet wall on the other hand, and the operating temperature of transformer is remained within the suitable scope, forms cooling system.
Below only expressed embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Advantage of the present utility model: simple in structure, science design radiator structure reaches the purpose that system stability is reliable, volume is little, quality is light, energy consumption is low.
