Description
Technical field
The present invention relates to a kind of radiator structure of Hybrid Vehicle power battery pack.
Background technology
Electrokinetic cell is the crucial control assembly in the hybrid vehicle system, and its performance quality will influence the vehicle performance quality.The temperature field of electrokinetic cell distributes and directly influences unbalanced degree between battery useful life, battery Specifeca tion speeification and the battery module, the research and development of battery pack heat management system are essential for modern electric automobile, and the heat monitoring and the heat management of battery pack are significant to the car load security of operation.As " highway communication science and technology " 03 phase in 2005, the Insight that mentions the mixed power electric car Prius of Japanese Toyota Company and Honda company in " key technology of Thermal Management System for EV Battery Packs " literary composition has adopted the mode of air cooling.Draft type with the air cooling heat radiation generally has serial and walks abreast two kinds, as depicted in figs. 1 and 2.Under the serial draft type shown in Figure 1, cold air is blown into from the right side from the left side and blows out.Air constantly is heated in flow process, so the cooling effect on right side is poorer than the left side, battery pack temperature from left to right raises successively in the battery case.Shown in Figure 2, parallel draft type makes air mass flow distribute more equably between battery module.Parallel draft type need be to intake and exhaust channel, and the battery arrangement position is designed well.What the new Prius of Toyota adopted is exactly parallel aeration structure, the intake and exhaust channel of its wedge shape makes that slit pressure differential up and down is consistent substantially between disparate modules, guarantee to blow over the consistency of the air mass flow of different battery modules, thereby guaranteed the consistency of battery pack temperature field distribution.But, in the experiment of actual battery temperature field, find that battery pack intermediate cell temperature is higher, and parallel aeration structure, the intake and exhaust channel of its wedge shape is difficult to guarantee the consistency of battery pack temperature field distribution.This in addition structure is not easy to processing, in the on-line debugging systematic procedure, is not easy to the problem of discovery in real time in the debugging of battery temperature field.
Summary of the invention
The objective of the invention is to weak point at prior art, design a kind of radiator structure of Hybrid Vehicle power battery pack, this structure is by the improvement to the battery pack intake and exhaust channel, and determine the flow control of fan by corresponding temperature acquisition, thereby realize the heat monitoring and the heat management of battery pack, improve battery useful life and car load safety in operation.
The radiator structure of the hybrid vehicle power battery pack that the present invention proposes includes batteries, air intake water conservancy diversion cover plate, storage battery support plate, storage battery base plate and scavenger fan.Described batteries supports by the storage battery support plate, and is fixed on the storage battery base plate, and air intake water conservancy diversion cover plate covers batteries from top, fixes by connecting bolt and storage battery support plate.Improvement of the present invention is: on air intake water conservancy diversion cover plate corresponding to all oblique air inlet guiding gutter that has in the position of every cell batteries, space between the notch inclination subtend two row batteries of air inlet guiding gutter, and with the groove width of air inlet guiding gutter and water conservancy diversion angle size design for to increase gradually along mind-set both sides in the batteries.Scavenger fan is installed under the storage battery base plate, and is relative with the batteries center, and every group storage battery is corresponding installs a scavenger fan, and at scavenger fan outer cover exhaust water conservancy diversion frid.
In addition, batteries is provided with temperature sensor, connects the cooling system signal processing unit by holding wire.
The present invention can effectively control the air inlet flow by the air inlet guiding gutter of certain width certain angle is set at air inlet water conservancy diversion cover plate, makes battery pack cell temperature equalization in charge and discharge process.Simultaneously by at scavenger fan for exhaust water conservancy diversion frid is set, the hot-air that fan is discharged through exhaust water conservancy diversion frid interflow after, the hot-air that fan is discharged is discharged battery housing smoothly, be discharged in the atmosphere by the car load air channel again and go.By mounting temperature sensor in battery pack, gather temperature and ambient temperature in the battery pack, by the flow of cooling system signal processing unit controlling fan air draft, make battery pack be operated in 0～30 ℃ of scope.
Therefore, the present invention compares with existing correlation technique, can keep the consistency of cell temperature in the battery pack, thereby guarantees the consistency of each cell performance of battery pack, and is simple and compact for structure, is convenient to the car load mounting arrangements.
