2, use cooling system of the present utility model, adopt brushless motor, improve the radiating efficiency of fan.
Accompanying drawing explanation
Fig. 1 is the utility model hybrid vehicle cooling system structure schematic diagram;
Fig. 2 is the utility model hybrid vehicle cooling system workflow diagram.
Detailed description of the invention
Specific implementation method of the present utility model is as follows:
For traditional cooling system for vehicle, dispel the heat primarily of driven by engine fan, so just make fan always in running order, when not needing heat radiation, fan also can not quit work, cause the waste of ability, and the rotating speed of fan also can not increase according to temperature or reduce, this will cause driving engine not to be in optimum working temperature, thus reduces engine operating efficiency; And for motor vehicle driven by mixed power, driving engine is not necessarily always in running order, so the demand of vehicle heat radiation can not be met completely by driven by engine fan work.The hybrid vehicle cooling system that the utility model provides, cooling mechanism for motor vehicle driven by mixed power devises a set of cooling system and control method thereof, motor vehicle driven by mixed power cooling mechanism comprises driving engine, motor, electric machine controller, air-conditioning compressors etc. need the device of heat radiation, at above-mentioned each device place, fan is set, the unified control of cooling management system is used for all fans, and with temperature collecting device monitor everywhere temperature feedback to cooling management system, unlatching and the shutoff that real-time actv. controls each group of fan is reached with this, accelerate and slow down, realize closed loop control.
The utility model hybrid vehicle cooling system is illustrated below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model hybrid vehicle cooling system comprises cooling management system, fan electromotor, fan, cooling mechanism, temperature collecting device etc.Described cooling management system is connected with described fan electromotor, described fan is connected with described fan electromotor, described fan is placed in described cooling mechanism etc. to be needed near the device place of heat radiation, in order to give each device radiation, described temperature collecting device is connected with described cooling mechanism, for each unit temp of Real-Time Monitoring, described temperature collecting device is connected with described cooling management system, the temperature that monitoring gathers is sent to described cooling management system by described temperature collecting device, cooling management system adoption rate regulates and integral adjustment realizes each cooling mechanism temperature of closed loop control.
Described cooling mechanism comprises engine water tank, engine intercooler, motor and controller, air-conditioning compressor etc., described fan electromotor adopts DC brushless motor, there is higher work efficiency, described motor comprises drive motor, electrical generator, described electric machine controller comprises drive motor controller, engine controller, and described temperature collecting device is that temperature sensor etc. can gather and transmit the device of temperature.
For series parallel hybrid power vehicle, when starting or low speed driving, driving engine does not start, and drives vehicle operating by drive motor; During high speed, engine direct drives, and motor does not provide driving power; When climbing or acceleration, jointly drive vehicle by driving engine and motor; When sliding or brake, by electrical generator by recover kinetic energy in power supply.
The working process of this cooling system is illustrated below in conjunction with Fig. 2, Fig. 2 is the workflow diagram of the utility model cooling system, be placed in driving engine, motor, controller, the each unit temp data of temperature collecting device Real-time Collection at the cooling mechanism places such as air-conditioning compressor also transfer data to cooling management system, when temperature exceedes the upper limit T1 of set temperature, start fan, rotate with an initial speed, then now cooling mechanism temperature value Tt is gathered in t, and gather the temperature value Tt+ Δ t of subsequent time, relatively Tt+ Δ t and Tt, if Tt+ Δ t>Tt, namely temperature is in ascent stage, then choose first group of proportional control coefficient and integral adjustment coefficient to carry out fast speed and promote rotation speed of the fan, to reach fast to the effect of cooling mechanism heat radiation, if Tt+ Δ t≤Tt, namely temperature is in the decline stage, now chooses the reduction rotation speed of the fan that second group of proportional control coefficient and integral adjustment coefficient come slowly, and the moment detects the temperature feedback of cooling mechanism to cooling management system, when temperature is lower than lower limit T2, stopping fan rotation, otherwise continue to gather a certain moment temperature of cooling mechanism and subsequent time temperature, repeat appeal process, reach the effect of closed loop control with this.Above-mentioned first group of proportional control coefficient and integral adjustment coefficient are greater than second group of proportional control coefficient and integral adjustment coefficient, can ensure that cooling mechanism temperature fan when rising can raise rapidly like this and reduce unit temp, and slowly reduce rotation speed of the fan in the cooling mechanism temperature decline stage, prevent rotating speed from reducing suddenly the rise of cooling mechanism temperature.A closed loop is formed like this by cooling management system, fan electromotor, fan, temperature collecting device, temperature everywhere can either be controlled by actv. in real time, can not need somewhere again reduce this place's fan motor rotational speed or stop this place's fan motor runs, economize energy when heat radiation.This closed cycle cooling system can ensure that the temperature of each cooling mechanism maintains a stable value, and the operating temperature that this guarantees driving engine continues the state in the best, improves the work efficiency of driving engine; And described fan electromotor is DC brushless motor, substantially increases motor working efficiency.
Fan, fan electromotor that the utility model is developed for cooling system of hybrid vehicle are same model, conveniently install, and for follow-up maintenance bring convenient.
For being one exemplary embodiment of the present utility model; should be understood to be claims of the present utility model protection domain in a certain demonstrative example wherein; there is directiveness effect those skilled in the art being realized to corresponding technical scheme, but not to restriction of the present utility model.
