Problems solved by technology

Excessive contamination of the cooling air flow, e.g. with sand, iron, copper, salt and polluted water, leads to accelerated corrosion of the cooler
In addition, when the cooling unit is arranged under the floor, it can be assumed that, in addition to the sand, a large amount of water is sucked in, thereby impairing the function of the cooler

Embodiment Construction

[0035] according to Figure 1 to Figure 8 Preferably, it means that the rail vehicle 1 of a diesel locomotive includes at least one rail vehicle cooling system 2 [h2], and the rail vehicle cooling system may also be referred to as the cooling system 2 for short below. The cooling system 2 includes a cooler 3, which is based on Figure 5 Encapsulated in the cooling circuit 4, the coolant, which is usually liquid, circulates in the cooling circuit. in figure 1 The cooling air path 5 indicated by the arrow in the middle runs through the subcooler 3, and the cooling air path is used to guide the cooling air flow 6, which is indicated by the same arrow and is generated when the cooling system 2 is running. In addition, the rail vehicle 1 also has a frame 42 on or in which the cooling system 2 is arranged and the frame has a vehicle floor 13.

[0036] In addition, the cooling system 2 also includes at least one separator 7, which is arranged upstream of the cooler 3 in the cooling air ...

Abstract

The invention relates to a rail vehicle cooling system (2) for a rail vehicle (1) having a cooler (3) enclosed in a cooling circuit (4) for conducting liquid coolant and for A cooling air path (5) leading a cooling air flow (6) runs through the cooler; and has a separator (7) arranged upstream of the cooler (3) in the cooling air path (5) for separating the cooling Liquid and / or solid impurities of the air flow (6), wherein the separators (7) each have a separator structure (8) through which the cooling air flow (6) can flow and the separated impurities Convey to collection box (10). Increased reliability is also achieved at high vehicle speeds. The invention also relates to a rail vehicle.

Description

Technical field [0001] The invention relates to a rail vehicle cooling system for rail vehicles, and a rail vehicle equipped with a rail vehicle cooling system. Background technique [0002] This type of rail vehicle cooling system may generally have a cooler that is packaged in a cooling circuit for guiding a liquid coolant, and a cooling air path for guiding a flow of cooling air passes through the cooler. A separator for separating liquid and / or solid impurities of the cooling air flow may be arranged upstream of the cooler in the cooling air path. In this way, a certain degree of cleaning of the cooling air flow can be achieved. Excessive contaminants such as sand, iron, copper, salt and contaminated water in the cooling air flow can cause accelerated corrosion of the cooler. In addition, when the cooling unit is placed under the floor, it can be estimated that in addition to sand, a large amount of water is sucked, which will impair the function of the cooler. [0003] The ...
