Abstract
The utility model relates to a kind of rectifier of gasoline Permanent Magnet and Electric electric welding generator, comprise rectifier anode fin, rectifier negative pole rear end cap radiator, rectifier diode, it is characterized in that: rectifier diode is fitted on rectifier anode fin and rectifier negative pole rear end cap radiator by polarity respectively, rectifier anode fin is fixed on rectifier negative pole rear end cap radiator by insulated heat-conducting medium isolation.Rectifier negative pole rear end cap radiator is the rear end cap of welding generator, and be plane outside rectifier negative pole rear end cap radiator, center is ventilation hole; Rectifier anode fin is the annular fin of a plane, and there is ventilation hole at center.Its advantage is: good heat dissipation effect, and working relative humidity is low.The contact area of positive pole radiator and end cap readily conducts heat greatly, with having a narrow range of temperature of end cap.Rectifier working relative humidity is low, and long-term work is not fragile.
Description
Technical field
The utility model relates to the rectifier of gasoline electric welding generator, especially a kind of rectifier of gasoline permanent direct-current electric electric welding generator.
Background technology
Current gasoline electric welding machine is widely used, and especially gasoline permanent direct-current electric electric welding generator effect is better, well received.Too compact due to the design of gasoline electric welding generating set, rectifier is arranged on the inside of welding generator, and during electric welding work, electric current is very large, and radiating condition is bad, and rectifier is overheated, and the phenomenon that rectifier anode rectifier diode damages often occurs.The heat radiation of rectifier diode becomes the greatest problem of existing gasoline electric welding generator.
Summary of the invention
The utility model provides a kind of good heat dissipation for above problem, not easily crosses the rectifier of the gasoline permanent direct-current electric electric welding generator of cause thermal damage.
Scheme of the present utility model is: comprise rectifier anode fin, rectifier negative pole rear end cap radiator, rectifier diode, it is characterized in that: rectifier diode is fitted on rectifier anode fin and rectifier negative pole rear end cap radiator by polarity respectively, rectifier anode fin is fixed on rectifier negative pole rear end cap radiator by insulated heat-conducting medium isolation.Rectifier negative pole rear end cap radiator is the rear end cap of welding generator, and be plane outside rectifier negative pole rear end cap radiator, center is ventilation hole; Rectifier anode fin is the annular fin of a plane
,there is ventilation hole at center, and the insulated heat-conducting medium that the inner plane of rectifier anode fin and the outerplanar of rectifier negative pole rear end cap radiator have contact area larger is isolated.
Its advantage is: the good heat dissipation effect of rectifier negative pole rear end cap radiator, working relative humidity is low.The contact area of rectifier anode fin and rectifier negative pole rear end cap radiator is large, readily conducts heat, with having a narrow range of temperature of rectifier negative pole rear end cap radiator.Rectifier working relative humidity is low, and long-term work is not fragile.
Accompanying drawing explanation
