Abstract
An air compressor concentric annular valve cylinder head, comprises radiating fin, air-inlet cavity, air vent and relief opening thereof, and air-inlet cavity communicates with the external world through intake interface, and air vent is periphery in the periphery of described air-inlet cavity, and intake interface is arranged on the top of described air-inlet cavity.Take distance described relief opening farthest is starting point, and the degree of depth of air vent is two-way to be increased gradually, with relief opening intersection be bosom.The utility model improves gas interface side to after being set to vertically to arrange, and has avoided the eclipse phenomena of original structure, has improved wind cooling effect; Moreover, the variation of groove depth structure, make cylinder head top form good heat radiation windward side, the setting of clearance groove makes the temperature of input and output gas influence each other and drops to minimum, and the air vent cross-sectional passage of inverted " U " font has advantages of that gas flow drag losses is few.
Description
[technical field]
The utility model relates to a kind of air compressor, especially relates to a kind of air compressor concentric annular valve cylinder head.
[background technique]
In compressor industry, there is following common recognition: generally adopt the cooling small air compressor of wind, the air cylinder head structure of its adapted directly affects the performance of air compressor, for example energy efficiency, reliability and working life thereof, for this reason, little and good heat dissipation effect that a kind of good cylinder head at least should have advantages of that gas flow drag losses is few, the temperature of input and output gas influences each other, and meet simple in structure, with low cost, the requirement of be applicable to producing in enormous quantities.Consideration based on this common recognition, the applicant thought before the utility model is made, there is following problems in the small air compressor of prior art: 1, the concentric annular valve cylinder head of adapted, because its suction port is arranged on the side of cylinder head, therefore, wind cooling effect is subject to the impact of the stopping of the assemblies such as air-strainer, windward side structure and is unsatisfactory; 2, the intake and exhaust chamber in cylinder head each other only a wall be separated by, and the wall area of being separated by sharing is excessive, has encouraged hot conduction, makes intake temperature significantly increase.
[summary of the invention]
For solving the problems of the technologies described above, the utility model aims to provide a kind of air compressor concentric annular valve cylinder head, and that this cylinder head has advantages of is simple in structure, good heat dissipation effect, gas flow drag losses is few and inlet exhaust gas temperature influences each other little.
For solving the problems of the technologies described above, the utility model has adopted following technical proposals, this air compressor concentric annular valve cylinder head, its structure comprises radiating fin, air-inlet cavity, air vent and relief opening thereof, described air-inlet cavity communicates with the external world through intake interface, described air vent is periphery in the periphery of described air-inlet cavity, it is characterized in that: described intake interface is arranged on the top of described air-inlet cavity; Take apart from described relief opening farthest is starting point, and the degree of depth of described air vent is two-way to be increased gradually, and extremely intersection's terminal of described relief opening is for the darkest.
Furtherly, the leptoprosopy of described radiating fin and cooling air direction match.
Furtherly, described air vent protrudes at the lip-deep outer wall of cylinder head, forms a low early and high after windward side.
Again furtherly, the relief opening of described air vent is located at the back side of windward side.
Again furtherly, between described air-inlet cavity and air vent, there is clearance groove.
While more specifically implementing, the sectional shape of described air vent is inverted " U " font substantially.
Beneficial effect: compared with prior art, the utility model has been avoided the eclipse phenomena to cooling air after intake interface is changed into and vertically being arranged, and air-strainer, connecting tube are arranged on the top of cylinder head, can not affect cooling wind action.Moreover, by changing air vent groove depth structure, set up clearance groove, the sectional shape of air vent being changed into the technical measures such as inverted " U " font, brought following effect: 1, the variation of groove depth structure, makes cylinder head top form the windward side that is conducive to good heat radiating.2, the setting of clearance groove makes the temperature of input and output gas influence each other and drops to minimum.3, the cross-sectional passage of " U " font has advantages of that gas flow drag losses is few.
Below in conjunction with accompanying drawing, by embodiment, the utility model is described further.
[accompanying drawing explanation]
Fig. 1 is an embodiment's of the utility model perspective view.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the B-B cross-sectional view of Fig. 1.
In figure: air-inlet cavity 1, suction valve docking port 11, intake interface 12, air vent 2, air vent anchor ring 21, relief opening 22, windward side 23, angle 24, clearance groove 25, radiating fin 3.
[embodiment]
Referring to Fig. 1, Fig. 2 and Fig. 3.This air compressor concentric annular valve cylinder head, its structure comprises radiating fin 3, air-inlet cavity 1, air vent 2 and relief opening 22 thereof.Air-inlet cavity 1 communicates with the external world through the intake interface 12 at top, during assembling, is connected with air-strainer.Air vent 2 is periphery in the periphery of air-inlet cavity 1, and take apart from relief opening 22 farthest is starting point, and the degree of depth of air vent 2 is two-way to be increased gradually, is finally intersected in relief opening 22, and with the intersection of relief opening 22 be bosom.As seen from Figure 2, the degree of depth of air vent 2 increases from left to right gradually, the darkest during to relief opening 22 intersection.The variation of the air vent 2 this degree of depth, the effect of bringing is: air vent 2 is protruded at the lip-deep outer wall of cylinder head, form a low early and high after windward side, be intended to increase radiating effect.The leptoprosopy of radiating fin 3 should match with cooling air direction (arrow indication in Fig. 2).
During concrete enforcement, for improving the cooling effect of cooling air, the relief opening 22 of air vent 2 is preferably located at the farthest of cooling air, is located at the back side of air intake surface.Between air-inlet cavity 1 and air vent 2, offer clearance groove 25, be intended to increase both heat diffusion area, improve radiating effect.
The sectional shape of air vent 2 is changed into and being substantially after inverted " U " font, can reduce the circulating resistance of cell wall to gas.Facts have proved: " inverted U-shaped " air vent 2, except above-mentioned effect, also has increasing heat radiation area, improves exhaust cavity 1 bearing strength, and the effect of cooling air water conservancy diversion.
The cylinder head of this structure can adopt upper and lower matched moulds, and aluminum alloy die-casting technological is produced manufacture in enormous quantities.
Above-described embodiment is only explanation flesh and blood of the present utility model, and should not be considered as the concrete restriction to the utility model structure, and any simple deformation design of having done according to embodiment, all should include protection domain of the present utility model in.
