The rotor within compressor 31 is driven to rotate to improve gas pressure.It is to say, compressor 31 be by
Kinetic energy drives operating, rather than by the compressor of electrical energy drive.Above compressor 31 be only embodied as kenel
For purposes of discussion, the most not so limited, in some aspects, described compressor 31 is the most past
Twin compressor or scroll compressor.
Specifically, described compressor 31 is attached to above-mentioned refrigerator 33, to be incited somebody to action by refrigerator 33
The cooled medium of gaseous coolant (air or water) of the high pressure-temperature that above-mentioned compressor 31 is compressed is condensed into
The liquid refrigerants of the middle temperature of high pressure, is then transformed into the liquid refrigerants of middle for high pressure temperature via expansion valve (not illustrating)
The liquid refrigerants of low-temp low-pressure, the gaseous state that last re-evaporation (as passed through vaporizer) absorbs heat into low-temp low-pressure is cold
Matchmaker, to produce and to export sub-cooled gas.Use and engine 10 is carried out cooling effect, make engine
10 are able to maintain that in preferably operating temperature.
Form by said structure, the engine 10 produced power that operates can be enable directly to drive compression
Machine 31 operates, and makes compressor 31 directly drive refrigerator 33 to produce cooling gas, with to engine 10
Cool down.It is to say, compressor 31 is not necessary to still further (as dynamic in civil power or recovery by external power source
The electric energy that the power of power machine 10 is changed) power supply, reach energy-conservation function and purpose.And engine 10
Produce power be not necessary to through conversion can produce cooling effect and reach reduce energy loss return with kinetic energy
The improved efficiency received, and then promote system whole efficiency.
As in figure 2 it is shown, be the system architecture diagram of this utility model motor cooling system the second embodiment, in
In the present embodiment, motor cooling system 1 has further included electromotor 20, and above-mentioned electromotor 20 includes one

A driving member 60 (such as belt group, gear train, chain group or shaft coupling group) is utilized to be connected to power output
Axle 11, and can be dynamic to receive machinery produced by engine 10 with power output shaft 11 synchronous axial system
Can and change into electric energy.For example, electromotor 20 can include coil and magnetic part, when electromotor 20
When receiving the kinetic energy of engine 10 and operate, sense can be produced in two interpolars rotations of magnetic part by band moving winding
Induced current, makes kinetic energy be converted into electric energy.
Hold above-mentioned, be all to be connected to power by mechanically operated mode by electromotor 20 and compressor 31
The technical characterstic of the power output shaft 11 of machine 10, makes electromotor 20 can synchronize reclaim dynamic with compressor 31
Kinetic energy produced by power machine 10.In other words, electromotor 20 is able to receive that kinetic energy produced by engine 10
And operate, so that the kinetic energy of recovery is converted into electric energy.And compressor 31 also is able to synchronize to receive engine 10
Produced kinetic energy and operate, to carry out the function of above-mentioned refrigeration, be not necessary to still further by external power source (as
The electric energy that civil power or electromotor 20 are reclaimed) power supply, reach energy-conservation function and purpose.
It addition, compressor 31 also can share the load of electromotor 20, reach to reduce the loss of energy conversion,
Make recoverable improved efficiency, and then promote system whole efficiency.For example, if engine 10
Output is 100KW, then electromotor 20 can provide 90KW bearing power, and compressor 31 can provide
The bearing power of 10KW, say, that electromotor 20 reclaims kinetic energy produced by 90% engine 10,
Compressor 31 reclaims kinetic energy produced by 10% engine 10.Thereby, due to moving that electromotor 20 reclaims
Can reduce, therefore be converted into electricity loss of energy and the most also can relatively reduce.In detail, if electromotor 20 will be dynamic
Can be converted to electricity loss of energy is 5%, and owing to compressor 31 can share the load of electromotor 20, therefore,
Electromotor 20 reclaims 90% and moves loss of energy and can reclaim 100% move loss of energy less than electromotor 20.
Additionally, due to the electric energy that compressor 31 is not necessary to still further be reclaimed by electromotor 20 is powered, therefore,
Electromotor 20 is changed electric energy produced by kinetic energy and is not necessary to further be supplied to compressor 31, can avoid another
Secondary convert electric energy to kinetic energy and produce loss.Therefore, this utility model can reach to reduce energy conversion
Loss, makes recoverable improved efficiency, and then the advantage promoting system whole efficiency.

Output may produce slight variations and cause generator loading power and compressor load total power
It is not equal to the output of engine 10.
Additionally, in some aspects, controller 40 also the mode of passing ratio can distribute generator loading merit
Rate and compressor load power.Such as, controller 40 can set generator loading power and compressor load
Power is 9 to 1, if therefore the output of engine 10 is 100KW, then generator loading power is
90KW, compressor load power is 10KW.
Again as it is shown on figure 3, in the present embodiment, motor cooling system 1 has further included electric power reclamation plant
50 (such as storage battery or electrical networks), to reclaim electric energy produced by above-mentioned electromotor 20, and electric power reclamation plant
The electric energy reclaimed is exported to electricity needs equipment 70 by 50.For example, electric power reclamation plant 50 can provide
Factory's entirety required electric power, or controller noted above 40 or other measuring instrument required electric powers.Additionally, electric power
Retracting device 50 also can provide startup engine 10 required electric power.
