Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of in rail vehicles the equipment of cooling accumulator, this equipment can be implemented to compare so far and more effectively cool off.
Above-mentioned technical problem is solved like this according to the present invention, and accumulator directly is connected aspect the thermodynamics with vaporizer, and vaporizer and condenser are the parts of the closed circuit of refrigerator.
The advantage that adopts refrigerator to bring is that the heat that forms in accumulator can shed rapidly and reliably.By the cyclic process of refrigerator, provide enough cooling agents all the time.Therefore, even the extra high accumulator of electric load and thermic load also can be cooled reliably.In addition, also the advantage of Huo Deing is, can be a plurality of accumulators being installed than much smaller so far spacing, and however still have good cooling possibility.An additional advantage is, this refrigerator low noise work, so ratio such as the lower interference noise of cooling agent air blast generation.
For example, be connected with condenser by compressor, and condenser is connected with vaporizer by flow controller as the vaporizer of the part of compression refrigerator.
By another kind of example, the vaporizer as the part of absorbing type refrigerator be connected with condenser by compressor, and condenser is connected with vaporizer by thermocompressor.
The advantage that no matter adopts the compression refrigerator still to adopt absorbing type refrigerator all to obtain is, even if the extra high accumulator of electric load and thermic load also can be cooled reliably.
Compression refrigerator and absorbing type refrigerator all are known.The cooling agent of condensation only by the flow controller compression, is supplied with vaporizer then in the compression refrigerator, and absorbing type refrigerator adopts thermocompressor, and it is a kind of dissolving circulation.Cooling agent at first is dissolved in the liquid there, and heat sheds this moment.Then, the cooling agent of dissolving is discharged from solution by the input outside heat.Cooling agent ratio after this process originally had higher density.
In order to derive heat energy, it for example is connected aspect the thermodynamics with the heat cycles that is used for the heating of rail vehicles passenger carriage from thermocompressor.Advantageously utilize the heat that produces thus.
For heat energy is supplied with thermocompressor, it for example is connected aspect the thermodynamics with the used heat pipe of rail vehicles.That is to say,, need import heat energy from the outside in order to discharge cooling agent from solution.By utilizing the used heat pipe of rail vehicles, described heat energy does not advantageously need independent generation.
Accumulator for example is an electric energy accumulator, for example is electrochemical capacitance (UltraCap) or double layer capacity.
By another kind of example, accumulator is electrochemical energy storage device, for example battery.This battery can for example be a nickel-cadmium cell.
For example a plurality of accumulators only are connected with a vaporizer.Because only the power of a refrigerator just is enough to the heat that produces is discharged from a plurality of accumulators, so can advantageously cool off a plurality of accumulators in little space.
For example condenser is connected aspect the thermodynamics with the heat cycles that is used for the heating of rail vehicles passenger carriage.Advantageously utilize the heat that in the condenser of refrigerator, produces thus.
For control/adjustment cooling procedure in rail vehicles, for example there is a control module.The advantage of bringing thus is that cooling procedure can adapt with needs.
For example control module is made from multiple components, and these parts can be installed in the rail vehicles in case of necessity with distributing.
The accumulator that cools off can be in the vehicle end of rail vehicles, at the vehicle interior diverse location, under on the roof or floor.Rail vehicles also can be city railway or long distance train except that the city railroad electric car.But the cooling device of accumulator also can be used in locomotive, for example in the shunter, or is used in and is equipped with in the vehicle that rubber tyre orbits.
Adopt advantage that equipment of the present invention obtains especially, even electric load and the extra high accumulator of thermic load and correspondingly a series of closely accumulator arranged side by side, also can be reliably and low noise be cooled.Obviously prolong the service life of accumulator thus.In the tramcar that blockiness was travelled at least when this equipment especially can be placed in not from externally fed well.
