Specific embodiment
The utility model proposes a kind of complete more hot-fluid integrated heat pipes of weather vehicle to manage system, including power battery branch, sky
Branch and fuel cell branch are adjusted, air-conditioning branch includes the air-conditioning module without radiator, is done after three branch circuit parallel connections with hot-fluid
Road is connected, and successively string sets air conditioner heat radiator, fuel cell heat sink and water pump 5 on hot-fluid main line, passes through switch valve independent control
Power battery branch, air-conditioning branch and fuel cell branch are realized that the switch valve of independent control can be and are arranged on hot-fluid main line
On four-way valve 1, four-way valve is one-way conduction；Switch valve is also possible to be respectively set one-way valve in power battery branch
Road, air-conditioning branch and fuel cell branch road one-way valve.
It can make fuel cell, power battery and air-conditioning three by the control of four-way valve 1 or the one-way valve of each branch road
Refrigerant environment between person keeps to each other mutually indepedent；The both ends parallel connection first switch branch of power battery branch, it is described
First switch branch road setting first flow regulating valve 2, hot-fluid main line and second switch branch and third switching branches in parallel, institute
Second switch branch circuit parallel connection is stated in air conditioner heat radiator both ends, second switch branch road setting second flow regulating valve 3, third switch
Third flow control valve 4 is arranged in branch circuit parallel connection on fuel cell heat sink both ends, third switching branches, as shown in Figure 3.
System, the control management process of automobile at all seasons are managed based on the above-mentioned more hot-fluid integrated heat pipes of full weather vehicle
It is as follows:
Spring/in the fall, it does not need to open air-conditioning, the heat dissipation for fuel cell, the specific conduction status of pipeline are as follows:
Water pump 5 and fuel cell are opened, flow control valve 3, flow control valve 4, flow control valve 2 are simultaneously switched off.Because of fuel cell
Shared with the refrigerant of power battery, with circulation of the refrigerant in pipeline, the heat of power battery and fuel cell passes through air-conditioning
Radiator and fuel cell heat sink dissipate, and during this, although not turning on the aircondition, heat passes through air conditioner heat radiator
A part of heat can be dissipated, in conjunction with the effect of fuel cell heat sink on hot-fluid main line, radiating requirements is can satisfy, also achieves
Equipment makes full use of.In addition, by the increase of radiator area, then air quantity required for radiating can also be reduced, accordingly
The fan power consumption of fuel cell heat sink is reduced, and then can significantly reduce the energy consumption of vehicle.
In summer, needing to open air-conditioning, the fan of air-conditioning can be used for radiating to fuel cell and power battery,
The specific conduction status of pipeline are as follows: open water pump 5, fuel cell and power battery, while opening air conditioner refrigerating mode, and disconnect
Flow control valve 3, flow control valve 4, flow control valve 2.Air-conditioning under refrigeration mode is substantially a heat generating components, due to altogether
The refrigerant enjoyed circulates in fuel cell, air-conditioning and power battery, a large amount of heat that fuel cell, air-conditioning and power battery generate
It is all to be dissipated by the effect of the refrigerant of air conditioner heat radiator and fuel cell heat sink, the mutually coordinated work of the two realizes vehicle
More hot-fluid integrated heat pipe reasons exist meanwhile, it is capable to effectively reduce the heat dissipation capacity of two radiator heat-dissipation fans to reduce fan
Energy consumption in rotation process, so that reducing the energy consumption of entire heat management system.
In winter, before fuel cell start-up: the electricity of the electric heating and air-conditioning that contain on fuel cell heat sink adds

Heating mode, the fuel cell heat sink of air-conditioning, and flow control valve 3 is opened, close flow control valve 4, flow control valve 2.
With circulation of the refrigerant in pipeline, the heat that the electric heating of air-conditioning module and fuel cell heat sink generates will be transmitted to power
Battery, fuel cell, make it be rapidly heated, so as to work normally as early as possible.Under the action of air conditioner heat radiator, pass through adjusting
The open degree of flow control valve 3 can control the heat into power battery, and the temperature of power battery is made to maintain suitable model
It encloses.After opening air-conditioning module ventilation function, hot-air is transferred to passenger compartment, improves the comfort level of passenger compartment in winter.
After start up of the fuel cell: the specific conduction status of pipeline are as follows: open water pump 5, while opening fuel cell and sky
It adjusts, and opens flow control valve 3, flow control valve 4, flow control valve 2.The amount of heat that fuel cell generates, is transmitted to dynamic
Power battery and air-conditioning, the open degree by adjusting flow control valve 2 can be heated to power battery, and can be controlled into power electric
The heat of pond branch makes the temperature of power battery maintain suitable range；The heat that fuel cell generates passes through coolant transmission
To air-conditioning module, it is subsequently used for heating air, after opening air-conditioning module ventilation function, hot-air is transmitted to passenger compartment；Pass through stream
Adjustable valve 3, flow control valve 4 open degree can control and the heat of passenger compartment is entered by air-conditioning (more heats pass through
Radiator is dissipated, then less heat enters passenger compartment by air-conditioning), it maintains passenger compartment temperature in suitable range, improves
Comfort level.
Above embodiment is complete set, realizes the full weather vehicle of refinement control more hot-fluid integrated heat pipe reasons system
System, as other embodiments, the application can will control the four-way of power battery branch, air-conditioning branch and fuel cell branch
Valve replaces with the respectively arranged corresponding single-pass switch valve in each branch road；In addition, power battery branch can not the first electricity in parallel
Flow branch, on hot-fluid main line can not also second switch branch in parallel and third switching branches, be also able to achieve the application by one
Heat management system is covered, realizes the utility model thought of unified heat management.
The utility model specific embodiment is presented above, but the utility model is not limited to described embodiment party
Formula.Under the thinking that the utility model provides, to above-mentioned implementation by the way of being readily apparent that those skilled in the art
Example in technological means converted, replaced, modified, and play the role of and the utility model in relevant art means base
This purpose of utility model that is identical, realizing is also essentially identical, and the technical solution formed in this way is finely adjusted to above-described embodiment
