Specific embodiment
In order to make those skilled in the art more fully understand the technical solution in the utility model, below in conjunction with this reality
With the attached drawing in new embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that
The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on the utility model
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
The range of the utility model protection all should belong in example.
In addition, duplicate label or mark may be used in various embodiments.These are repeated only for simple clear
Ground describes the utility model, and not representing has any relevance between the different embodiments or structure discussed.
Join shown in Fig. 1, the utility model proposes a kind of oil cooled system systems, are mainly used for used in pure electric automobile
Oil-cooled motor 100 is cooled down；Specifically, oil cooled system system includes oil pump 200, oil filter 300, heat exchanger 400, manograph
And regulating valve 500；Wherein, the oil circuit between oil pump 200, oil filter 300, heat exchanger 400 and oil-cooled motor 100 successively connects
Connecing composition has the first circuit recycled for cooling oil；Between oil pump 200, regulating valve 500, heat exchanger 400 and oil-cooled motor 100
Oil circuit be sequentially connected composition have for cooling oil circulation second servo loop, particularly, the cooling oil in the present embodiment is set as moistening
Lubricating oil can also be lubricated oil-cooled motor 100 while may be implemented to radiate to oil-cooled motor 100.
Further, the oil pump 200 in the present embodiment is set as electric oil pump, is mainly used for providing output pressure and suction
To drive cooling oil to recycle in the first circuit or second servo loop；Oil filter 300 is mainly used in filter oil pump 200 output to the
Impurity in the cooling oil of primary Ioops is to reduce the abrasion of transmission system, to extend the service life of oil cooled system system；Heat exchange
Device 400 is mainly used for cooling down filtered cooling oil to the heating device in oil cooled system system.
Meanwhile the manograph in the utility model is mainly used for the pressure that real-time detection flows into the cooling oil of oil filter 300
And it is denoted as detection pressure value, and then make regulating valve 500 according to detection pressure value to adjust open and-shut mode；Specifically, in this implementation
In example, manograph is set as pressure sensor and integrates to be set in regulating valve 500, and between manograph and regulating valve 500
By communication connection, so that the pressure signal that manograph detects can be timely feedbacked to regulating valve 500.
Meanwhile regulating valve 500 is set in oil filter 300 in the present embodiment, with save oil cooled system system cost and
Coiling requirement is simplified, certainly, in the utility model other embodiments, regulating valve 500 may be set to be relief valve, or
Other can be according to the valve body for the pressure control opening and closing that manograph detects.
Further, the oil cooled system system in the utility model is additionally provided with pressure threshold, and the pressure in the present embodiment
Threshold value is set as 15 kPas, it is to be understood that in the utility model other embodiments, pressure threshold can also be cold according to oil
The climatic characteristic and height above sea level on the specifically used ground of system are set.
Specifically, regulating valve 500 is kept in normal vehicle operation and when detecting pressure value less than or equal to pressure threshold
