Abstract
The utility model discloses a light rail vehicle traction converter ventilation system, wherein an air inlet, a filter screen and a centrifugal fan are combined into an air supply module; a heat dissipater, a heat dissipater case and an air outlet are combined into a heat dissipation module; an air supply module and two heat dissipation modules are combined into a ventilation system; the air supply module and the heat dissipation module are connected via an air deflector; and the two heat dissipation modules are symmetrically mounted at two sides of the air supply module. In installment, the air supply module and one heat dissipation modules are assembled outside the light rail vehicle, the air supply module and the other heat dissipation module are mounted in the cabinet of the traction converter; in detachment, the air deflector is firstly detached, and the air supply module and the heat dissipation modules are detached later. The utility model divides ventilation system into three detachable modules which are connected via the movable air deflector, to make installment and detachment simple, make maintenance simple and avoid sucking rainwater.
Description
Technical field
The utility model relates to a kind of light railway van traction current transformer ventilating system, particularly relates to a kind of traction current transformer ventilating system that uses in light rail car, tramway train finite space.
Background technology
The traction convertor installing space of light rail car is limited, and power demand is bigger, so the heat dissipation ventilation of light railway van traction current transformer has relatively high expectations, and in addition, because most of light railway van traction current transformer is installed in roof, the classification of waterproof of current transformer requires also very high.Traditional traction convertor radiator ventilation system has two kinds, a kind of is the water-filled radiator ventilation system, the advantage of water-filled radiator ventilation system is the radiating efficiency height, switching valve radiator volume is little, shortcoming is to safeguard extremely inconvenience, safeguards improper when serious even meeting permanent damage water-filled radiator ventilation system; A kind of is air-cooled aluminium radiator ventilation system, and the advantage of air-cooled aluminium radiator ventilation system is that cost is low, installs simply, and shortcoming is that the aluminium radiator volume is big, and radiating efficiency is low.In addition, because most of light railway van traction current transformer parts packing densities are bigger, cause the cooling system layout comparatively complicated, install, dismantle cumbersome, especially in airborne dust more season, light railway van traction current transformer needs regular dismounting to get rid of dust, owing to do not adopt modular design, causes changing filter screen, gets rid of dust, more bothers very much during ventilating fan.
Traction convertor radiator ventilation system is very crucial in a traction convertor link, in case the heat radiation unfavorable condition occurs, will burn the traction convertor switching valve probably, causes whole traction convertor to quit work.
Summary of the invention
For solving existing the problems referred to above in the prior art, the utility model will design a kind of later-model modular removable light railway van traction current transformer ventilating system.
For achieving the above object, the technical solution of the utility model is achieved in that a kind of light railway van traction current transformer ventilating system, comprise ventilation inlet, filter screen, centrifugal compressor, deflector shield, radiator, radiator shell, air outlet, described ventilation inlet, filter screen, centrifugal compressor is combined into the air feed module, described radiator, radiator shell, air outlet is combined into radiating module, be combined into a ventilation system by an air feed module and two radiating modules, connect the symmetrical respectively both sides that are installed in the air feed module of described two radiating modules between described air feed module and the radiating module by deflector shield.
Radiator described in the utility model is a heat-pipe radiator.
Ventilation inlet described in the utility model is positioned at air feed module bottom central authorities.
Centrifugal compressor described in the utility model is the big centrifugal compressor of power to volume ratio.
Compared with prior art, the utlity model has following beneficial effect:
1, because the utility model becomes detouchable three big modules with Design of Ventilation System, independent fully each other, by connecting by movable deflector shield, make installing/dismounting very convenient, also make maintenance maintenance become very easy simultaneously.
2, because ventilation inlet of the present utility model is positioned at bottom of cabinet bulk central authorities, air outlet is positioned at the cabinet both sides, has both changed the direction of air intake, air-out, can fully suck cabinet bottom cold air again, simultaneously because ventilation inlet away from the cabinet side, can avoid sucking rainwater.
3, because the utility model has changed the aluminium section bar radiator of conventional art into the heat-pipe radiator heat radiation, accelerate the thermal cycle of switching valve, strengthened the switching valve cooling performance.
4, because the utility model has adopted the big centrifugal compressor of power to volume ratio, improve the power of blower fan to greatest extent, greatly improved the fanning effect of traction convertor.
Description of drawings
The utility model has 3 accompanying drawings, wherein:
Fig. 1 is the light railway van traction current transformer ventilating system structural representation.
Fig. 2 is a light railway van traction current transformer ventilating system air feed module diagram.
Fig. 3 is a light railway van traction current transformer ventilating system radiating module schematic cross section.
Among the figure: 1, ventilation inlet, 2, filter screen, 3, centrifugal compressor, 4, deflector shield, 5, radiator, 6, radiator shell, 7, air outlet.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further detailed.Shown in accompanying drawing 1-3, a kind of light railway van traction current transformer ventilating system, comprise ventilation inlet 1, filter screen 2, centrifugal compressor 3, deflector shield 4, radiator 5, radiator shell 6, air outlet 7, described ventilation inlet 1, filter screen 2, centrifugal compressor 3 is combined into the air feed module, described radiator 5, radiator shell 6, air outlet 7 is combined into radiating module, be combined into a ventilation system by an air feed module and two radiating modules, connect the symmetrical respectively both sides that are installed in the air feed module of described two radiating modules between described air feed module and the radiating module by deflector shield 4.Described radiator 5 is a heat-pipe radiator.Described ventilation inlet 1 is positioned at air feed module bottom central authorities.Described centrifugal compressor 3 is the big centrifugal compressor of power to volume ratio 3.
When installing, the utility model outside the light rail car, assembles earlier air feed module and radiating module, then the air feed module is installed on traction convertor bottom of cabinet bulk central authorities, the ventilation inlet 1 of air feed module is aimed at the ventilation inlet 1 of bottom of cabinet bulk central authorities, two radiating module symmetries are installed on the both sides of air feed module, deflector shield 4 is installed between air feed module and radiating module at last again, remove deflector shield 4 during dismounting earlier, and then dismounting air feed module and radiating module.Described air feed module and radiating module are installed does not have sequencing, and dismounting does not have sequencing yet.
Prove through real running, ventilation type radiating efficiency height of the present utility model, maintenance is convenient, is fit to very much be installed on the roof ventilation system as traction convertor.
