Export the galvanic rectifier bridge of 500A in current energizing apparatus power cabinet and mostly adopt Section Bar Heat Sinks and cast radiator is two-sided press-fits rectifier cell, and adopt multilayer to connect the form in air channel.It is inner that rectifier bridge is arranged on narrow dish cabinet mostly, adopts single blower fan forced air cooling, and series connection air channel causes the rectifier cell of levels to produce temperature difference, directly affects situation of exerting oneself and the useful life of each rectifier cell.
Utility model content
Goal of the invention of the present utility model is to provide a kind of good cooling results, can avoid the parallel air duct rectifier bridge producing temperature difference between each rectifier cell.
Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of parallel air duct rectifier bridge, comprise some groups of radiators and several rectifier cells, several rectifier cells described are fitted in described some groups of radiators, it is characterized in that, described parallel air duct rectifier bridge also comprises a both ends open, the air channel that limit wall is airtight, the friendship of described rectifier cell, DC bus passes from the back side in described air channel, described some groups of radiators are all vertically arranged in same level, be positioned at described air channel inner, described some groups of radiators are kept apart by vertical insulating barrier to each other, described air channel is separated into some sub-air channels.
The radiator press-fiting rectifier cell is arranged in same level by the utility model, forms parallel air channel, and cooling air once passes all radiators, good cooling results, and avoids temperature difference.
Described radiator is 3 groups, and described rectifier cell is 6, and often organize radiator and press-fit two rectifier cells, form a three-phase full-controlled rectifier bridge, the cross section in described air channel is rectangle, and radiator described in 3 groups arranges point-blank along the long limit in described air channel.The utility model only has 3 sub-air channels, air channel negligible amounts, when identical air quantity, blast and wind speed relatively large, cooling effect is better.
Described radiator is cast aluminium radiator.
In order to improve radiating effect of the present utility model further, described parallel air duct rectifier bridge also comprises crossing current cooling blower, and the air outlet of described crossing current cooling blower is relative with the lower ending opening in described air channel.
Described air channel is made up of upper and lower, and described radiator is positioned at the top in described air channel, and the bottom in described air channel tilts to the back side in air channel, makes the bottom in air channel consistent with the wind direction of crossing current cooling blower, each sub-air channel of being led by wind so that better.
Described air channel is inner, be provided with two bar insulation supporting traverses along its two long limit, and described radiator stand is located on described insulating supporting crossbeam, and the front panel on the top in described air channel is made up of transparent protection force-bearing plate.
Relative to prior art, parallel air duct rectifier bridge compact conformation of the present utility model, neat appearance, often organize radiator and press-fit two rectifier cells, 3 groups of radiator levels are placed with layer, and cooling air is once through radiators all in airtight air channel, and air channel windage is little, good cooling results, and avoid between each rectifier cell and produce temperature difference.
Accompanying drawing explanation
Fig. 1 a, 1b, 1c are respectively the utility model and have press-fited the vertical view of the radiator of rectifier cell, left view and front view;
Fig. 2 a, 2b, 2c are respectively three structural representations of the parallel air duct rectifier bridge of the utility model preferred embodiment, and wherein, Fig. 2 b is the left view of Fig. 2 a, and Fig. 2 c is that the C of Fig. 2 b is to schematic diagram.
Embodiment
The utility model adopts 3 groups of SF15CL cast aluminium radiators to press-fit 6 rectifier cells and forms a three-phase full-controlled rectifier bridge, concrete mounting means is as shown in Fig. 1 a, 1b, 1c, and two DC buss, an ac bus of rectifier cell are drawn from radiator side through radiator respectively.
As shown in Fig. 2 a, 2b, 2c, the parallel air duct rectifier bridge of the present embodiment comprises the radiator 4 that the airtight air channel 2 of a both ends open, limit wall and three groups have press-fited rectifier cell.Air channel 2 cross section is rectangle, be made up of upper and lower, the front panel on top, air channel 2 is made up of transparent protection force-bearing plate 5, backboard is made up of shrouding 5 after insulating, bottom, air channel 2 tilts to the back side in air channel 2, be provided with crossing current cooling blower 1 below air channel 2, the air outlet of crossing current cooling blower 1 is relative with the lower ending opening in air channel 2.
Traditional air channel 2 is all adopt to install at air channel 2 end face air exhauster to promote in air channel 2 airflow circulating in the mode of exhausting, and the utility model adopts the mode of blowing, is conducive to the utilance improving wind, thus improves radiating effect.In addition, the bottom in the utility model air channel 2 tilts to the back side in air channel 2, and it is consistent with the wind direction of crossing current cooling blower 1 that object is to make air channel 2 shape, each sub-air channel on top, air channel 2 of being led by wind so that better.
Air channel 2 upper inner, be provided with two bar insulation supporting traverses, 3,3 groups of radiators 4 along its two long limit and be erected on insulating supporting crossbeam 3, its AC and DC bus passes from the back side in air channel 2.3 groups of radiators 4 are all vertically arranged in same level, and arrange point-blank along the long limit in air channel 2.3 groups of radiators 4 are kept apart by vertical insulating barrier 6 to each other, air channel 2 are divided into three sub-air channels.
The radiator 4 having press-fited rectifier cell is arranged in same level by the utility model, all rectifier cells are also positioned in same level, and cooling air is once through all rectifier cells, and air channel windage is little, good cooling results, and avoid the temperature difference between each rectifier cell.In addition, the utility model adopts one group of radiator to press-fit two rectifier cells, makes air channel negligible amounts, when identical air quantity, blast and wind speed relatively large, cooling effect is also better.
