Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
As long as in addition, technical characteristic involved in each embodiment of the utility model disclosed below each other it
Between do not form conflict can be mutually combined.
Fig. 1 is a kind of schematic diagram of self-priming air cooling system of the utility model embodiment.Wherein, it is pressurized to improve centrifugation
The cooling effect of device, the utility model use self-priming air cooling system, its general principle be siphoned away using negative pressure it is remaining in support
Heat vortex, so as to reach good radiating effect.Specifically, natural wind enters support 4 from transmission system cooling blast pipe 3
It is interior, as friction pulley group 2 rotates at a high speed, and the high temperature vortex air-flow of aggregation in support is taken away, because centrifugal impeller group 8 is at a high speed
Rotate under operating mode, produce larger negative pressure, so that the high temperature vortex air-flow in support enters transmission system cooling duct 5, and
After being filtered to it by cooling down wind filter 6, compressor air inlet 9 is then entered back into, is rotated at a high speed through centrifugal impeller group 8
After pressurization, engine is sent into through compressor air outlet 10.
Fig. 2 is a kind of structural representation of self-priming air cooling system of one preferred embodiment of the utility model.Such as Fig. 2 institutes
Show, the system includes：Transmission system cooling blast pipe 3, transmission system cooling duct 5 and compressor blast pipe 11.Wherein, it is driven
System cooling blast pipe 3 is installed in the opening of the side of support 4, is offered opening in the opposite side of support 4, is driven for installing
System cooling duct 5, the planform of the transmission system cooling duct 5 determines according to residing extraneous position, for example can set
Matrix pipeline is calculated as, one end is connected with the opening on support 4, and the other end is connected with the opening on compressor blast pipe 11.Calm the anger
Machine blast pipe 11 may be designed as cylindrical straight tube or be designed to bend pipe according to actual conditions, and its one end is connected with compressor casing 7,
So as to form a complete airflow pipeline.
During work, natural wind enters in support 4 from transmission system cooling blast pipe 3, is rotated at a high speed with friction pulley group 2, by
In centrifugal impeller group 8 in the case where high speed rotates operating mode, larger negative pressure is produced, therefore, the high temperature vortex air-flow in support is inhaled into biography
In dynamic system cooling duct 5, and enter by transmission system cooling duct 5 in compressor blast pipe 11, and in compressor air intake
After being mixed in pipe 11 with natural wind, enter through compressor air inlet 9 in centrifugal impeller group 8, rotated at a high speed by centrifugal impeller group 8
After pressurization, engine is admitted to from compressor air outlet 10, completes one cycle, the circulation so to go round and begin again, realization pair
The cooling of centrifugal supercharger.Self-priming air cooling system of the present utility model, when being worked using booster in compressor intake stack
Caused negative pressure, a large amount of hot blasts in support are sucked in the intake stack of compressor and enter compressor, after compressor pressure
Base outer is discharged, achieves good cooling effect.
Further, since centrifugal impeller group 8 rotate at a high speed caused by negative pressure, by support high temperature vortex air-flow suck mechanism of qi
In air inlet 9, the intake of compressor air inlet 9 is considerably increased, so as to solve traditional cooling system intake deficiency
Problem, and cooling air quantity is bigger, and cooling effect is better.Experiment find, have self-priming air cooling system centrifugal supercharger compared with
Common centrifugal supercharger, the temperature in support can reduce by 20~30 DEG C, substantially increase and improve cooling effect, extend
The service life of centrifugal supercharger.
As another key improvements of the present utility model, in a preferred embodiment of the present utility model, it is being driven
Cooling wind filter 6 is provided with system cooling duct 5.Because friction pulley group 2 rotates at a high speed, in support 4 hot-air can not and
When discharge, with the superhigh speed of friction pulley group 2 one rotate, produce vortex, the working time of centrifugal supercharger is longer, the temperature in support 4
Degree is higher, especially summer, and up to 80 DEG C, the lubricant grease in support 4 easily melts the temperature in support 4 at such high temperatures
Change and enter in thermal current, if these greasy dirts enter engine with air-flow, easily cause engine failure, influence automobile
Safety.Therefore, the utility model while being cooled down to centrifugal supercharger, is provided with transmission system cooling duct 5
Wind filter 6 is cooled down, when the high temperature vortex hot-fluid in support 4 pass through transmission system cooling duct 5, the cooled mistake of wind filter 6
After filter, compressor air inlet 9 is entered back into, most enters engine after supercharging afterwards, removes greasy dirt well, avoid the captain that calms the anger
Time assembles greasy dirt, influences normal work.
Above-mentioned self-suction air system structure diagram is only a preferred embodiment of the present utility model, all to be siphoned away using negative pressure
The self-suction air system architecture of waste heat vortex principle in support, belong to the row of protection of the present utility model.
As it will be easily appreciated by one skilled in the art that preferred embodiment of the present utility model is the foregoing is only, not
To limit the utility model, any modification of all made within spirit of the present utility model and principle, equivalent substitution and change
Enter, should be included within the scope of protection of the utility model.
