Describe in detail
Instance embodiment relates to such as the heat management system that can be used in the vehicle.Instance embodiment also relates to the method for heat management.
Like what this paper limited, term " energy accumulating device " has the scope that is different from " battery " commonly used that limit like this paper.In the place of listing term " battery ", relate to common battery such as lead-acid battery, it is sized to and is configured to be suitable for the running engine starter and can provide limited amount auxiliary burden energy to reach the short period.A Vehicular battery that instance is a standard like the battery that this paper limited.Like what this paper limited, the battery deficiency is so that perhaps otherwise provide power to Vehicular system and subtense angle the period that traction motor moves, makes the radiator fan operation to prolong constantly.With compare like the term " energy accumulating device " that this paper limited; Wherein " battery " so that traction motor motion, make the period that the radiator fan operation prolongs or supply auxiliary burden and exceed minimal function or surpass the short time, " energy accumulating device " can be carried out one or more in these functions with deficiency.In addition, energy accumulating device can be attached to dynamic braking system 150 (referring to for example Fig. 2 and associated description), to use traction motor charging (under this situation, dynamic braking system will with the regenerative braking mode operating) in response to the dynamic brake incident.An instance like the energy accumulating device that this paper limited will be lithium ion battery array, sodium metal halide array, sodium-sulphur battery array, nickel metal hydride battery array or nicad battery array.
Term " radiator " as this paper limited comprises the system of having loaded fluid, and it uses heat dissipation fin/structure and heat energy is passed to the environment from fluid.Especially, be to be used to make freezing mixture like the radiator that this paper limited from the heat of motor absorption or the device of thermal energy dissipation.Suitable radiator can comprise the piping section of the vertical or horizontal fin of the band that connects a plurality of jars.Radiator can be designed in pipe or path, keep a large amount of freezing mixtures, and this pipe or path have provided with environment or atmosphere contacted than large size.Freezing mixture (water that for example mixes with antifreezing solution) can pass motor and be circulated to radiator by water pump via radiator hose.For system with a plurality of radiators; These a plurality of radiators can be: the parallel connection (in same cooling circuit; But be arranged in the independent path of cooling circuit; Wherein, for the given loop of the freezing mixture that passes through this loop, the freezing mixture that passes a radiator in loop does not pass another radiator in loop); (in same cooling circuit, and be arranged in the same path of cooling circuit, wherein, for the given loop of the freezing mixture that passes through this loop, the freezing mixture that passes a radiator in loop can pass another radiator in loop) of series connection; Perhaps non-connection, wherein, the radiator of non-connection is independent and the part cooling circuit that nonfluid connects.
The fan (one or more) of the electrical motor driven of mechanically throwing off in one embodiment, can reduce or eliminate one or more design constraintss of vehicle.Such constraint can comprise: radiator and fan all be installed on vehicle front end and/or with motor along row (inline); Radiator has height and width (for example being square) about equally; And radiator can be configured to use with single fan compatiblely.
Various embodiments' disclosed herein layout can allow one or more in the feature: a plurality of fans that have existing radiator; The non-square radiator; A plurality of and different radiating device; The flexibility that motor is directed; And a plurality of motors or Engine-Generator group (" generator set ").
In one embodiment, used a plurality of fans, wherein each fan is by the electric radiator fan motor operation that is attached to such as the power supply of energy accumulating device.The a plurality of fans that use with existing radiator allow: with respect to standard fan have the fan of minor diameter more, uniformity, scopodromic cooling air flow or directive air stream, fault tolerant operation, improved life of equipment and the modular fan of increase of air stream through radiator changed and maintenance.
The use of a plurality of less relatively fans can reduce the relative size and the cost of heat management system.Especially; Single large-scale fan can cause that the uneven air stream through radiator is arranged, and the corresponding uniformity that the use of a plurality of fans can cause having a plurality of air streams through same or similar radiator to transmit with the overall uniformity of improving air stream and the heat from the radiator to the moving air.A plurality of fans can be located such that air flows or circulation on each comfortable direction in the spreader region of the extra cooling of needs.Whole members if not fans were lost efficacy, and then the use of a plurality of fans will allow to come operational outfit and heat management system with the capacity that reduces.The remaining fan that can move of fans will continue to radiator refrigerating function to be provided.This situation will allow the productivity of increase, because vehicle need not to withdraw from immediately (sidelined) up to the fan (like contingent situation in single fan design) that obtains to change.Even vehicle must withdraw from from full-time task keeping in repair, the array fan of part operation still can allow vehicle arrival maintenance facility under its own power of withdrawing from, thereby has avoided dragging away the needs of this vehicle.In addition, the challenge of the replacing of the fan unit of inefficacy maybe be less than the replacing of the fan unit of routine because the fan unit that lost efficacy will need mechanically not throw off with motor, but only on electricity, breaks off with power supply and with any supporting bracket disengagement.What in addition, less fan unit will be than conventional fan unit is single lighter relatively than big fan.
The non-square radiator is used in the system of the electrical motor driven of mechanically throwing off.Though conventional square radiator can be optimized to the circular scanning of single fan, the use of a plurality of fans allows the non-square radiator to be configured with use efficiently.For example, the rectangle radiator of non-square (for example, having the width that is twice in its height) can hold two or more fans.The width of expansion radiator keeps approximately simultaneously, and identical total surface area or cooling effectiveness can allow the design that allows to reduce the radiator height.
Can use the radiator of a plurality of and different (or repelling each other), each radiator has the fan (one or more) of himself.This structure can allow further away from each other motor that radiator is installed.For example, radiator can be installed on other position on the vehicle, rather than forwardly central.Suitable position can be included in side portion of vehicle, at the perhaps the place ahead or the rear of front tyre.This will allow motor to be disposed in relatively more the place ahead.The motor that is arranged in the place ahead can make it possible to the space requirement of keeping in repair proximity preferably and reducing framework.Away from motor radiator is installed and is also allowed motor that the cooling of more efficient is arranged, because unlikely the heat interpolation is back in the motor from the heat of radiator.
Can also change the motor orientation, because will need not aim at mechanical fans connecting piece and fan.In one embodiment, motor can be along horizontal installation.In another embodiment, motor can keep portrait orientation with respect to vehicle, but can be reverse and/or mobile backward with respect to the chassis.This orientation can allow for example in neck sheath part (horsecollar), to have relative alternator than minor diameter.This alternator can allow to reduce the neck sheath part size.
In one embodiment, can use one group of a plurality of motor.The size of these motors maybe be less relatively, and can be used as generator set.For generator set, being susceptible to motor will only be started when needs for example provide power in hybrid vehicle and used.Therefore, when low power uses, but some motor idling or stop, to reduce or to eliminate fuel use and toxic emission.In addition, reducing size of engine can allow in generator set, to arrange and locate each context engine that flexibility is largely arranged.In an alternative, the motor in the multiple-motor group is different from each one another at least one aspect.As difference relative to each other, these aspects can comprise position, rated horsepower, fuel used type, the speed of their operations (perhaps being optimized to operation efficiently) etc.Under the situation of needs, can use cascade than puffer, the motor that wherein only needs at any one time is in service.In addition, can adopt the less motor of size to come electric charge to be provided, make energy accumulating device be in full capacity when needed to energy accumulating device.
In another embodiment, fan needn't mechanically be thrown off with motor.For example, energy accumulating device and motor can serve as the replenishing of mechanical connection of fans drive, and perhaps vice versa, for example, when motor move, as the mode of preservation electric power, and when motor separates, keep the power of fan.
