Description
Technical field
The utility model relates to fuel cell heat management system, is specifically related to fuel-cell vehicle cooling loop system.
Background technology
Facing mankind energy shock and ecological deterioration problem, thus electronlmobil will become the main flow of future automobile development, and fuel cell powered vehicle can solve energy shock faced by people and environmental problem, can solve again the too short problem of pure electric vehicle flying power.But, in fuel-cell vehicle, a lot of key all can produce a large amount of heats, in the course of the work as pile, drive motor, power control unit etc., if can not be discharged by heat in time, will have a negative impact to part, generally need refrigerant fluid to cool it.Therefore comparatively electronlmobil is more complicated for the cooling system of fuel-cell vehicle, arranges more difficult in finite space.Fuel-cell vehicle cooling loop is divided into pile cooling loop and power control unit cooling loop, adopts freeing pipe to be connected to expansion tank under normal circumstances and realizes degassing function.Because the part be arranged in cooling loop is more, single cooling loop vent design cannot meet exhaust requirements when adding inject cooling liquid, must design multichannel bleeder line, thus causes freeing pipe pipeline too much, the problem of difficult arrangement.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of cooling loop system of effective simplified cooling system circuit design.
For reaching above object, a kind of fuel-cell vehicle cooling liquid circulation circuit system being provided, comprising pile cooling loop and power control unit cooling loop; Pile cooling loop comprises expansion tank, pile water pump, pile radiator, intercooler and pile, described expansion tank, pile water pump are connected with pipeline successively with pile radiator, after intercooler and pile parallel connection, its entrance is connected with the outlet of pile radiator, and its outlet is connected to the entrance of pile water pump; Power control element cooling system comprises the expansion tank, power control unit water pump, power control unit radiator and the drive motor that connect successively with pipeline, and drive motor delivery piping connects the entrance of power control unit water pump; At the vertex of pile cooling loop, at least one automatic exhaust steam valve is installed; At the vertex of power control unit cooling loop, at least one automatic exhaust steam valve is installed.
Described vertex refers to the parts that vertical direction is the highest in location layout.
Described automatic exhaust steam valve is the parts of the adjustment pressure that this area is commonly used, and is made up of floating drum and valve rod, and when pressure is greater than system pressure, floating drum falls to being with ovable valve stem to move downward, and valve port is opened; Otherwise then valve port is closed.
Concrete, described intercooler is the vertex on pile cooling loop, and intercooler is provided with automatic exhaust steam valve.Or described pile radiator is the vertex on pile cooling loop, pile radiator is provided with automatic exhaust steam valve.
Concrete, described power control unit radiator is the vertex of power control element cooling system, and power control unit radiator is provided with automatic exhaust steam valve.
Preferably, have three automatic exhaust steam valves, wherein intercooler and pile radiator are all the vertex on pile cooling loop, and power control unit radiator is the vertex of power control unit cooling system; Intercooler, pile radiator and power control unit radiator are respectively provided with an automatic exhaust steam valve.
Fuel-cell vehicle cooling loop system of the present utility model completes degassing function by vertex automatic exhaust steam valve being arranged on two cooling loops with this, instead of the exhaust pipe structure on cooling loop, effectively can complete the function of exhaust, simplify the circuit design of cooling system while reaching good exhaust effect, solve the problem of the too much difficult arrangement of freeing pipe pipeline.
The beneficial effects of the utility model are, without the need to installing freeing pipe on car load, thus simplify circuit design, and car load pipeline arrangement space is easy, decreases integral vehicle cost.
