Engine heat dissipation system used for railway engineering mechanical vehicle

Abstract

The invention relates to an engine heat dissipation system used for a railway engineering mechanical vehicle. The engine heat dissipation system comprises a radiator assembly (1), a bracket assembly (2) and a movable shutter (5), wherein the radiator assembly (1) is supported by the bracket assembly (2); the radiator assembly (1) comprises a radiator framework (9), an electric motor (6), a heat dissipation fan (7) and a radiator core body (8) which is horizontally arranged on the top of the radiator assembly (1), so that floor space is saved; four asynchronous motors drive the heat dissipation fan (7) to dissipate heat for the radiator core body (8), and the heat dissipation fan (7) sucks air inside a vehicle body and then perpendicularly blows the air to the outside of a vehicle top after passing through the radiator core body (8), so that exchange between air inside the vehicle body and air outside the vehicle body can be effectively promoted, and hot air is prevented from being repeatedly sucked into the vehicle body.

Description

technical field [0001] The invention relates to the technical field of railway machinery, in particular to an engine cooling system for railway engineering machinery vehicles. Background technique [0002] At present, the radiators of the engine cooling systems of domestic railway engineering vehicles are mostly located at the rear end of the engine, and are arranged vertically, with two modes of blowing and suction. Among them, most of the blowing methods need to design an air guide device to guide the hot air blown out of the radiator to the outside of the car body and eliminate it. Most of the suction methods need to consider the air intake requirements of the radiator, and reserve a certain air intake space at the front end of the radiator. The above two methods need to occupy a large installation space no matter the design of the air guiding device or the reservation of the air intake space, which in turn affects the layout of the entire power transmission system.

AI Technical Summary

Problems solved by technology

The invention can solve the problem that the engine radiator of the existing snow removal vehicle blows backward to dissipate heat at the same time, which increases the temperature of the subsequent engine, causing the power to decrease and the fuel consumption to increase

However, the radiator is installed on the frame of the snow removal vehicle, which takes up a large installation space and affects the layout of the entire power transmission system.
