Embodiment Construction

[0026] When the locomotive runs at high speed, the relative movement of the car body and the surface air produces high-speed airflow. The present invention uses this high-speed airflow to cool the diesel engine radiator and reduce the power consumed by the driving fan. The radiator is connected to the water pipe from the diesel engine high-temperature system. The water cooled by the radiator circulates back to the diesel engine through the return pipe. The connection of this part of the water pipe is omitted in each figure. The front and back mentioned in the text refer to the locomotive running direction, the forward direction of the locomotive is forward, and the backward direction is backward.

[0027] In the energy-saving cooling system for diesel locomotives of the present invention, the position of the radiator 20 is firstly changed significantly, and moved from the side of the original car body to the front end of the locomotive compartment. In this way, the radiator is se...

Abstract

The invention discloses an energy-saving cooling system of an internal combustion locomotive. The cooling system comprises a heat radiator of a diesel engine, wherein the heat radiator is located at the front end of the carriage of the locomotive, the bottom plane of the heat radiator is installed on the underframe surface of the locomotive, and the heat radiator is lower than the lower plane of a ceiling of a fan room of the locomotive; a fan motor unit is arranged behind the heat radiator; two groups of shutters are arranged between the heat radiator and the fan motor unit, the two groups of shutters are symmetrically arranged relative to the longitudinal gravity center line of the locomotive, the front ends of the two groups of shutters are connected, and the two groups of shutters arespread toward two sides from front to rear in a broken line shape or curve shape; the fan motor unit is located in the region which is surrounded by the two groups of the shutters; the fan motor unitis fixed on a fan rotation platform; and the fan rotation platform rotates relatively to the locomotive through a rotation mechanism, and is provided with two stopping gears at an interval of 180 degree. The cooling system has the advantages that: by utilizing high-speed air flow generated by the running speed of the locomotive, the cooling of the heat radiator is achieved, the effective power consumption is reduced and the effective traction power is increased, thus the fuel of the diesel engine of the locomotive is effectively utilized and the cooling system is suitable for cooling of the internal combustion locomotive.

Description

Technical field [0001] The invention relates to the technical field of diesel locomotive cooling. Background technique [0002] At present, the existing diesel locomotive diesel engine cooling system uses a fan to drive air to cool the radiator, dissipate the heat generated by the diesel engine, prevent the diesel engine from overheating, and ensure the normal and safe operation of the locomotive. Generally, the side wall of the locomotive is used to take the wind, and a part of the power is allocated from the diesel engine to drive the cooling fan to achieve the wind. If the cooling fan is not working, airflow cannot be formed, and the air outside the side wall of the locomotive cannot enter the cooling radiator inside the car, and the water temperature of the diesel engine cannot be lowered. Only when the big fan keeps working can the wind outside the side wall of the locomotive enter the cooling radiator inside the car. As long as the diesel engine is working, the big fan mus...
