The present invention belongs to the field of railway locomotive. BACKGROUND [0002] In prior-art ventilating system of composite cooler of locomotive, air outside locomotive enters intaking chamber at roof of it through centrifugal sedimentation filter and plate-type strainer, is forced by ventilator to cool water and oil radiators and then blown back into atmosphere. The centrifugal sedimentation filter and plate-type strainer aim at bigger debris in air or rain. After being filtered by two of them, there are still a lot of escaped tiny objects such as dust, those deposited on fins of composite cooler will take adverse effect to heat dissipation. Hence filter of mesh screen is equipped with between ventilator and fins of water and oil radiators, preventing dust from being accumulated on ripple fins of cooler core. If the mesh of screen is sparse, effect of dust removal is not good; and if the mesh is dense, effect of dust removal is good but ventilation quantity will be decreased, influencing adversely heat dissipation. And that the filter of mesh screen needs to be cleaned or replace filter element periodically, otherwise accumulating too much dust on filter element will also result in reduction of ventilation quantity and heat dissipation of cooler. Because of filter of mesh screen being fixed in composite cooler, the cooler should be dismantled when cleaning or replacing filter element and it is very difficult.

DETAILED DESCRIPTION [0022] The technical solutions of the invention will be described below clearly and comprehensively with reference to the accompanying drawings, so as to make objects, technical solutions and advantages of the embodiments of the invention clearer. Obviously, the -4 embodiments are only a part of the embodiments of the invention. All other embodiments made by the skilled in the art without creative work, based on the embodiments presented herein, fall within the scope of the invention. [0023] Embodiment 1 [0024] Look at Fig. 1. This embodiment illustrates an air filter apparatus for composite cooler of the locomotive. The air inlet of housing 2 is connected with the air outlet of ventilator 1, the outlet of housing 2 is connected with the air inlet of radiator 4of oil and water. The electrostatic precipitation element in the housing 2 is a electrostatic metal plate 5 with structure of cross-stagger grid pieces, it is connected with DC power and insulated from the housing 2. The electrostatic metal plate 5 and the axis of air channel in the housing 2 intersect at an angle a with range of 500 ~75 . It is available that the tiny objects absorbed are directed by air-blowing force and their own gravities. The dust chamber 7 with funneling structure and a side door is located at the downstream of electrostatic metal plate 5, preventing tiny objects effectively from being kicked up. [0025] Look at Fig. 2 and 3, diversion trench 9 is formed between cross-stagger grid piece groups 8. Look at Fig. 4, grid pieces 10 are curved as L and cross-stagger each other at an angle b with the range of 450 ~60' . Look at Fig. 5, the section 11 of grid piece is as L. Because of the design of grid piece with L section, heaved curve and cross-stagger, adsorption area is increased as much as possible in the premise of ensuring the ventilation quantity. The slope formed by grid piece 10 is convenient for precipitated tiny objects coming together to diversion trench. [0026] Look at Fig. 6, the inside of housing 2 is equipped with dielectric rails 6, the rails 6 are fixed on the inner wall of housing 2. Electrostatic metal plate 5 can be installed in or dismantled out through the side door 17 of housing 2 and along rails 6. The structure of installing rails is convenient for dismantling and cleaning periodically electrostatic metal plate 5. Snap-in fixer is used for fixing electrostatic metal plate 5 onto rail 6 and linked mechanically with switchl4.1 against electric shock in Fig. 7. [0027] Look at Fig. 7, switch 14.1 against electric shock linked mechanically with snap-in fixer 14 of electrostatic metal plate 5 is in series connection in switching circuit of DC power for electrostatic metal plate 5.When closing the start button of ventilator 15, the contactor coils 12 and 13 of DC power for electrostatic metal plate and ventilator' working circuit are powered at -5 same time ,and the contacts of both contactors are closed, the ventilator starts operating. When the contact of contactor 12 of DC power is closed, the snap-in fixer 14 is closed and switch 14.1 against electric shock is on, electrostatic metal plate 5 is charged to precipitate dust; the snap-in fixer is open and switch 14.1 is off and ground-connected, the electrostatic metal plate 5 is discharged and can be taken out safely. [0028] Finally, it will be appreciated that the embodiments described above are only used to illustrate the technical solution of the invention rather than to limit it. Although the invention has been described in detail with reference to the above embodiments, the skilled in the art should appreciate that the embodiments of the invention can be modified and the technical features therein can be replaced equivalently without departing from spirit and scope of the invention.
