Detailed ways

The specific embodiment of the utility model will be further described below in conjunction with accompanying drawing:

With reference to Fig. 1, Fig. 2 and Fig. 3, the air-conditioning unit deflector device of the EMU embodiment of the present invention includes the air-guiding cover 1a respectively installed at the front and rear ends of the air-conditioning unit 3 of the EMU through plugging, riveting or welding, etc. And the shroud 1b and a flow distribution device 2 installed on the top cover of the air conditioning unit 3 and close to the air outlet 31 of the condensing fan of the air conditioning unit 3 by riveting. Wherein, both the wind deflector 1a and the wind deflector 1b are open on one side, the windward side is streamlined, and the cross section is a hollow shell similar to a triangle, and the flow diversion device 2 is open at the bottom, and the cross section is a hollow triangular prism shaped like a mountain. case.

The air-conditioning unit deflector of the EMU of the above-mentioned embodiment, wherein, the height, width and shape of the opening side of the deflector 1a and the deflector 1b are the same as the height, width and shape of the end of the air-conditioning unit 3 exposed outside the compartment 4. The shapes are the same, and the inclination angle α between the plane of the upper part of the wind deflector 1a and the windward surface of the wind deflector 1b and the plane of the respective opening sides is 40°-75°. In this way, when the EMU is running at high speed, the air resistance of the EMU at high speed can be reduced through the streamlined design of the windward side of the wind deflector 1a and the wind deflector 1b.

The air-conditioning unit deflector of the EMU in the above embodiment, wherein the inclination angle β between the first side 21 of the flow diversion device 2 and the top cover of the air-conditioning unit 3 is 40° to 45°, and the second side of the flow diversion device 2 The inclination angle γ between 22 and the top cover of the air-conditioning unit 3 is 30° to 35°, and the length of the diverter device 2 is 1.1 to 1.3 times the width of the air outlet 31 of the condensing fan along the transverse direction of the air-conditioner unit 3, in order to reduce the size of the diverter device. 2 air resistance, the height of the splitter 2 is generally not greater than 60mm.
