DETAILED DESCRIPTION

[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] A roof-mounted locomotive air conditioning unit comprises a chassis housing 1 and a top cover mounted thereon. A control box 3, a compressor 4, an electric heater 5, an evaporator 6, and a condenser 7 are integrated within the chassis housing. The chassis housing is enclosed by a bottom plate and four side panels. An internal fan 8 is provided within the chassis housing inside the first side panel, and a through-hole region is provided on a second side panel 10 opposite the first side panel. A fresh air assembly 12 is provided on a third side panel 11 between the first and second side panels. The fresh air assembly is connected to a fresh air electric control valve 13 within the chassis. The fresh air assembly is provided to filter incoming air and automatically control the air volume via the fresh air electric control valve. The through-hole region further enhances ventilation and heat dissipation.

[0021] The fresh air assembly includes a ventilation hole defined in the third side panel, and a fresh air cover 15 positioned outside the ventilation hole. The fresh air cover is hollow and has a top opening for inserting a plug-in plate 16, which is provided with a filter plate. The plug-in plate functions as a filter structure, making it easy to disassemble and replace the filter plate.

[0022] The top surface of the fresh air hood is inclined, and a guide plate 17 is provided inside the fresh air hood to guide the plug-in plate. The guide plate has a through hole. The guide plate is provided to guide the plug-in plate during insertion and to support the plug-in plate. Since the guide plate is inclined, the plug-in plate is also placed obliquely in the guide plate, covering the ventilation holes in the fresh air hood and facilitating air filtration.

[0023] A fresh air fixing frame is provided at the inner side of the third side plate at a position corresponding to the fresh air cover, and an L-shaped oblique baffle 18 is provided on the bottom edge of the fresh air fixing frame to adjust the direction of gas flow.

[0024] The top surface of the plugboard is provided with a handle 19, which makes it convenient to replace the plugboard.

[0025] The through hole area is composed of four through hole areas distributed in an array, each of which is evenly distributed with a number of through holes 20. There is a gap between two adjacent through hole areas. Since they are not connected together, the area of ​​the through hole area is increased on the one hand, and the ventilation and heat exchange effect is better on the other hand.

[0026] The connection of the compressor clamp is provided with a connecting bolt 21, and the connecting bolt between the two mounting brackets 22 of the compressor clamp is sleeved with a compressor clamp sleeve 23. By providing the sleeve, the friction force of the connection is enhanced, making the connection more secure.
