The circuit board body is fixedly connected to an aluminum radiator. The power elements are all fixedly connected with the aluminum radiator. The electric welding machine circuit board arrangement structure has the advantages of being good in heat radiation performance, long in service life and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of electric welding machine, particularly a kind of electric welding machine circuit plate arrangement.
Background technology
Electric welding machine is that the high-temperature electric arc that utilizes positive and negative polarities to produce when instantaneous short circuit carrys out scolder and the materials to be welded on consumable electrode, reach the purpose that makes their combinations, electric welding machine generally can be divided into two kinds by the out-put supply kind, and a kind of is AC power, and another kind is dc source.
Electric capacity, resistance and block power component on the circuit board of electric welding machine is all to arrange separately at present, particularly each block power component is screwed separately on circuit board, arrange that like this installation is comparatively loaded down with trivial details, when electric welding machine was worked in addition, power component can produce heat, and existing heat dissipation for circuit board poor performance, after electric welding machine continuous operation a period of time, power component is overheated burning easily, and service life is short.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and a kind of electric welding machine circuit plate arrangement of rationally distributed, perfect heat-dissipating is provided.
The purpose of this utility model can realize by following technical proposal: a kind of electric welding machine circuit plate arrangement, the circuit board body that comprises sheet, on described circuit board body, be fixed with several block power components, it is characterized in that, described circuit board body is fixed on an aluminium radiator, and each power component all is connected mutually with aluminium radiator.
This electric welding machine circuit plate arrangement is rationally distributed, and it is connected in power component on aluminium radiator, and the heat that produces when power component is worked so directly is passed to aluminium radiator, by aluminium radiator, is dispelled the heat, and the guaranteed output element works for a long time.
In above-mentioned electric welding machine circuit plate arrangement, described power component is lined up some row, on described aluminium radiator, by several screws, be fixed with the metal platen that quantity is consistent with the power component columns, the every corresponding row power component of metal platen also is pressed in aluminium radiator by this row power component.The power component of lining up some row is pressed in aluminium radiator by the metal platen of correspondence, and fixes by screw, arrangement convenience like this, and sound construction, and also metal platen also carries out heat transmission, further strengthened heat dispersion.
In above-mentioned electric welding machine circuit plate arrangement, described metal platen is steel plate.The steel plate hot transitivity is good, is convenient to the power component heat radiation.
In above-mentioned electric welding machine circuit plate arrangement, described circuit board body is connected mutually by insulating bolt and aluminium radiator.Insulating bolt avoids circuit board body and aluminium radiator to interfere electric conduction phenomena, guarantees that the circuit board body uses for a long time.
Compared with prior art, this electric welding machine circuit plate arrangement is rationally distributed, perfect heat-dissipating, can work for a long time by the guaranteed output element, has extended circuit board service life.
