Definitions
- the invention relates to a vehicle cooling system for a rail vehicle according to the preamble of claim 1.
- the invention also relates to a method for controlling a vehicle cooling system.
- the main components of a rail vehicle such as power converters or transformers of a trainset, are usually provided by means of a vehicle cooling system, such as, for example, EP 0 915 794 B1 and US Pat
- the vehicle cooling system in this case has a cooler - usually a liquid-air heat exchanger - and at least one fan, which promotes the cooling air to the radiator.
- the cooling air cools the cooling liquid in the cooler, which then flows to the main component and cools it.
- the cooling air can also cool secondary components of the rail vehicle, such as inductors, fly-type transformers, traction motors or control cabinets.
- the cooling air is divided after the blower and an outlet flow of the cooling air into the environment and a side stream of the cooling air fed to the secondary components.
- the amount of cooling air and thus the cooling capacity of the vehicle cooling system are controlled by the speed of the respective fan.
- the division of the cooling air into the outlet flow and the secondary flow also depends on the speed of the respective blower and on the geometric design of the vehicle cooling system.
- Sufficient cooling of the cooling liquid in the radiator and consequently the main components can be achieved even with a reduced cooling capacity of the vehicle cooling system and correspondingly at a low speed of the blower. Only at a high ambient temperature, the speed must the blower and accordingly the cooling capacity of the vehicle cooling system can be increased. With a reduced cooling capacity of the vehicle cooling system and correspondingly at a low speed of the blower, however, the secondary flow of the cooling air is too low, so that the secondary components are not sufficiently cooled. This can be avoided, for example, by operating the fan at a higher speed than necessary to cool the main components. Alternatively, the flow cross-section of the low-flow stream can be reduced relative to the flow cross-section of the secondary stream and increased in accordance with the flow resistance counteracting the outlet stream.
- the object of the invention is therefore to improve a vehicle cooling system of the generic type and a method for controlling a vehicle cooling system such that the described disadvantages are overcome.
- the present invention is based on the general idea, flow resistance in a vehicle cooling system for a rail vehicle depending on To control a load condition of the vehicle cooling system and thereby reduce energy losses in the vehicle cooling system.
- the vehicle cooling system comprises a cooler through which cooling air can flow for cooling at least one main component, to which downstream at least one fan chamber, each with a fan, adjoins.
- the at least one fan chamber in each case has a main outlet arranged downstream of the respective fan, through which outlet air can flow out of the vehicle cooling system.
- the at least one fan chamber also has a respective secondary outlet arranged downstream of the respective fan, through which a secondary component cooling air can flow for cooling at least one secondary component of the rail vehicle.
- the vehicle cooling system also has an exhaust air duct with an exhaust air outlet, through which the secondary component cooling air can be supplied from the secondary outlet of the at least one blower chamber to the at least one secondary component.
- a control device of the vehicle cooling system controls the cooling of the at least one secondary component with the secondary component cooling air.
- a flow cross-section of the main outlet of the at least one blower chamber can be changed by the control device. In a full load state of the vehicle cooling system, the flow cross section of the main outlet is maximized and in one of the partial load states of the vehicle cooling system, the flow cross section of the main outlet is reduced.
- the vehicle cooling system is thus operable in the full load condition or in one of the multiple partial load conditions.
- the full load state is characterized by a maximum speed and the multiple part load conditions are defi ned by a comparison with the full load lower speed of the respective fan.
- the several partial load states differ by the speed of the respective fan, wherein the speed can be variable or stepwise changeable. Accordingly, the number of partial load conditions of Vehicle cooling system to be infinite or limited. An energetically most favorable part-load condition arises in the vehicle cooling system at a minimum rotational speed, which is currently sufficient for cooling the at least one main component.

- the secondary component cooling air flows via the exhaust air duct to the at least one secondary component. Due to a total high amount of the conveyed cooling air and the amount of sub-component cooling air for cooling the at least one minor component in the full load condition of the vehicle cooling system is sufficiently high. Overall, both the at least one main component and the at least one side component are effectively cooled in the full load state of the vehicle cooling system.
- the flow cross-section of the main outlet is maximized, so that the maximum output of the fan can be reduced compared to conventional solutions. As a result, energy losses in the vehicle cooling system in the full load state can be advantageously reduced.
- the flow cross section of the main outlet is reduced in the partial load conditions of the vehicle cooling system compared to the full load condition.
- the flow resistance of the outlet air at the main outlet is increased.
- the flow cross-section of the main outlet decreases with the falling speed of the fan and is adapted in each of the partial load conditions such that regardless of the partial load condition of the vehicle cooling system sufficient for cooling the subcomponent cooling air flows to the at least one subcomponent. Consequently, the vehicle cooling system can be operated predominantly in the most energetically favorable partial load condition, which is defined by the minimum speed of the respective fan which is sufficient for cooling the at least one main component. Energy losses are thus significantly reduced compared to conventional solutions.
- the control device has at least one pressure-controlled and passively adjustable passive actuator for controlling the flow cross-section.

- the control device has at least one adjustable active actuator for controlling the flow cross section.
- the active actuator can be actively adjusted depending on the speed of the at least one fan.
