Abstract
The invention relates to the technical field of internal combustion engine ventilation structures, in particular to a novel converter and traction motor combined ventilation cooling arrangement structure. The novel converter and traction motor combined ventilation cooling arrangement structure comprises a variable flow cabinet and a traction motor, the variable flow cabinet is arranged above the traction motor, a locomotive air flue is arranged between the variable flow cabinet and the traction motor, the locomotive air flue is communicated with the traction motor, a same cooling tower serves as a cooling ventilation unit of the variable flow cabinet and the traction motor, the cooling tower is installed beside the variable flow cabinet, a cooling tower radiator is arranged on the upper portion of the cooling tower, a cooling tower draught fan is arranged below the cooling tower radiator, and an air outlet of the cooling tower radiator is communicated with the locomotive air flue. Impellers of the cooling tower draught fan are high-efficiency backward or mixed flow draught fan impellers. By means of the novel converter and traction motor combined ventilation cooling arrangement structure, space occupied by the arrangement of ventilation cooling devices of two components of a locomotive on the locomotive is sufficiently reduced, and overall layouts of the locomotive are effectively optimized.
Description
Technical field
The present invention relates to internal combustion engine ventilation aeration structure technical field, especially a kind of novel current transformer, the cooling arrangement of traction electric machine natural and mechanical combined ventilation.
Background technology
In general, the cooling of cooling and traction electric machine for AC drive diesel locomotive converter cabinet is arranged apart.Independently cooling device is set conventionally can to the current transformator power module in converter cabinet, i.e. our usually said cooling tower.It is to utilize water-cooled principle that the heat of current transformator power module is taken away by the radiator arranging on cooling tower.Axial flow blower usually used as wind regime power is arranged in cooling tower top, and radiator is arranged thereunder, and the hot-air after radiator heat exchange directly drains into outside car body.The ventilation of traction electric machine is cooling is that independently centrifugal blower group and air channel by arranging ventilates cooling.As shown in Figure 1.
But for some narrow gauge alternating current electric locomotive, especially outer corridor locomotive, the arrangement space of locomotive is very limited.Adopt again above-mentioned split type cooling, ventilating had often both been unfavorable for that locomotive integral arranged, had also limited the arrangement space of ventilation blower simultaneously, was also unfavorable for the optimization of blower performance.Above arrangement has started to manifest the limitation that its cloth is set up.
Summary of the invention
In order to overcome the deficiency of existing technology, the invention provides a kind of novel current transformer, the cooling arrangement of traction electric machine natural and mechanical combined ventilation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel current transformer, the cooling arrangement of traction electric machine natural and mechanical combined ventilation, comprise converter cabinet and traction electric machine, converter cabinet is located at traction electric machine top, between converter cabinet and traction electric machine, be provided with car body air channel, and this car body air channel communicates with traction electric machine, described converter cabinet and traction electric machine all adopt same cooling tower as cooling channel unit, this cooling tower is installed on by converter cabinet, cooling tower radiator is arranged in cooling tower top, cooling tower is connected with the water pipe of cooling tower radiator, blower fan of cooling tower is arranged in cooling tower radiator below, the air outlet slit of this cooling tower radiator communicates with car body air channel.
According to another embodiment of the invention, the efficient backward or flow-mixing blower fan impeller of impeller employing that further comprises described blower fan of cooling tower.
The invention has the beneficial effects as follows, the present invention has fully reduced the ventilation cooling device of locomotive two large parts and on locomotive, has arranged shared space, has effectively optimized the integral arrangement of locomotive.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is original structure schematic diagram.
Fig. 2 is structural representation of the present invention.
In figure 1, converter cabinet, 2, traction electric machine, 3, car body air channel, 4, cooling tower, 5, cooling tower radiator, 6, blower fan of cooling tower, 51, radiator air intake, 52, radiator air outlet slit, 7, traction electric machine blower fan.
Embodiment
If Fig. 2 is structural representation of the present invention, a kind of novel current transformer, the cooling arrangement of traction electric machine natural and mechanical combined ventilation, comprise converter cabinet 1 and traction electric machine 2, converter cabinet 1 is located at traction electric machine 2 tops, between converter cabinet 1 and traction electric machine 2, be provided with car body air channel 3, and this car body air channel 3 communicates with traction electric machine 2, described converter cabinet 1 all adopts same cooling tower 4 as cooling channel unit with traction electric machine 2, it is other that this cooling tower 4 is installed on converter cabinet 1, cooling tower radiator 5 is arranged in cooling tower 4 tops, cooling tower 4 is connected with the water pipe of cooling tower radiator 5, blower fan of cooling tower 6 is arranged in cooling tower radiator 5 belows, be convenient to directly enter next stage cooling air channel through the pressure air of blower fan.The air outlet slit of this cooling tower radiator 5 communicates with car body air channel 3.The performance requirement that static pressure based on cooling tower inner blower is had relatively high expectations, the impeller of blower fan of cooling tower 6 adopts efficient backward or flow-mixing blower fan impeller, can effectively reduce locomotive auxiliary power.
During work, the refrigerating mode of converter module still adopts blower fan in cooling tower as wind regime power, by the radiator on cooling tower, the heat of module is taken away, because the radiator outlet air themperature after heat exchange now also has very large gradient than the temperature of winding in motor, therefore utilize this temperature gradient, continuation is ventilated cooling to traction electric machine, the flow direction of air in this system is: outside air---filter---cooling tower radiator---blower fan of cooling tower---car body air channel---traction electric machine, thereby carry out cooling to converter cabinet and traction electric machine.
Whole arrangement of the present invention has effectively improved locomotive space availability ratio and has been convenient to performance of locomotive optimization, has good cooling effect simultaneously.
