Description
Technical field
The present invention relates to a kind of supply vehicle more particularly to a kind of Multifunctional mobile comprehensive power vehicles, belong to mobile electricity
Source device field.
Background technique
In existing power supply box body, since generator and other component work generate heat, the raising of case body temperature is led
Cause the decline of supply vehicle overall performance, it is therefore desirable to carry out cooling down in time.Exhausting is generally carried out by the fan of constant speed, is made fresh
Air is swept from air inlet to generator pair and other component, and out of my cabin by hot wind discharge, is achieved the effect that cooling.The prior art
The fan of middle speed variable, but controlled according to the intracorporal bulk temperature of entire case, it can not be according to particular elements
The characteristics of targetedly formulate cooling strategy.For example, influence supply vehicle overall performance two critical pieces, generator with
And internal battery, fever respectively have feature.
The best effort environment temperature of generator is 20-50 DEG C, and under best effort environment temperature, temperature can reach fuselage
50—70℃.When environment temperature increases, shell temperature is likely to be breached 80 degree or higher, if carrying out at this time only for environment temperature
Cooling, even if environment temperature is in appropriate range, but is also endlessly distributing heat in generator operation, sends out
Motor performance will receive larger impact, cannot be in optimal delivery efficiency.
Battery can distribute certain heat in charge and discharge process, if cooling down not in time, battery performance will be deteriorated.
Especially with the battery for after a period of time, having had a degree of aging, it is easier to generate heat than new battery, further
, due to that cannot radiate in time, the speed of aging can be accelerated weathered battery, be thusly-formed vicious circle.According to statistics, with
Requirement to output power it is higher and higher, the period that cell degradation needs replacing also becomes shorter and shorter, this and box house
Heat dissipation ineffective have direct relation.
In addition, temperature when temperature when generator is run is relative to battery-operated is higher, and generator generates heat
Amount is fast, almost runs at the beginning, entire casing is just brought rapidly up；And often (time is long after a period of operation for battery
The short state quality depending on battery itself) it just will be slow fever.When seek unity of action cooling strategy for generator when, due to
Battery fever is slower, may be cooled down, be resulted in waste of resources when not needing be cooling；If seeking unity of action for battery
Cooling strategy, then will lead to that cooling effect is bad, and then influence the energy efficiency of supply vehicle.
Furthermore generally after supply vehicle use, cooling system can continue working a period of time again, when box house ring
Border temperature reaches then to be stopped cooling down in reasonable range, natural heat dissipation to room temperature.However this mode makes there are obvious drawback
With after the completion, the temperature of generator and battery is higher relative to room temperature, relies on natural heat dissipation after environment temperature is up to standard, can make
The performance for obtaining generator and battery deteriorates.
It can be seen that the existing cooling scheme to radiate only for cabinet, at least having the disadvantage that cannot be directed to
Generator is targetedly cooled down, and causes generator that can not be in optimal operating temperature；It cannot be according to the reality of battery
When state, degree of aging etc. targetedly cooled down, and battery aging speed is caused to be accelerated, and service life is reduced.
