Abstract
The utility model discloses a cylinder cover for an air-cooled reciprocating-piston air compressor, comprising a suction cavity and an exhaust cavity, wherein the outer surfaces of the suction cavity and the exhaust cavity are provided with heat radiating fins, and air slots are arranged between the suction cavity and the exhaust cavity. The cylinder cover disclosed by the utility model has a simple structure, and can effectively reduce the temperature of air in the suction cavity when air suction is finished and also increase the efficiency of the air compressor.
Description
Technical field
The utility model relates to a kind of air-cooled reciprocating piston air compressor cylinder head.
Background technique
At present, the cylinder head of air-cooled reciprocating piston air compressor is mainly used in the suction of air compressor, exhaust passage, is generally symmetric design, and promptly air aspiration cavity and discharge chamber volume equate, separates with foundry goods in the middle of air aspiration cavity and the exhaust cavity.
But the metal partion (metp) in the middle of the air aspiration cavity of this structure and the exhaust cavity can be passed to air aspiration cavity with the heat in the exhaust cavity, and the air of air aspiration cavity heated, air temperature when making air-breathing the end in the air aspiration cavity raises, will cause the delivery temperature in the exhaust cavity to raise synchronously like this, reduce the efficient of air compressor simultaneously.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of air-cooled reciprocating piston air compressor cylinder head, and this air cylinder head structure is simple, and the gas temperature in the time of can making air-breathing the end in the air aspiration cavity effectively reduces, and improves the air compression engine efficiency simultaneously.
The utility model for the technological scheme that solves its technical problem and adopt is: a kind of air-cooled reciprocating piston air compressor cylinder head, comprise air aspiration cavity and exhaust cavity, be equipped with radiating fin on air aspiration cavity and the exhaust cavity outer surface, be provided with air groove between described air aspiration cavity and the exhaust cavity.Because the thermal conductivity of air has only 0.02454W/m.k, and the thermal conductivity of grey cast iron commonly used is 39.2W/m.k, and both differ nearly 1600 times, therefore is provided with this air groove and can effectively reduces the air heat transfer of air in air aspiration cavity in the exhaust cavity.
As further improvement of the utility model, described exhaust cavity is bigger than the volume of air aspiration cavity.
As further improvement of the utility model, the spacing between the radiating fin on the gap ratio air aspiration cavity outer surface between the radiating fin on the described exhaust cavity outer surface is little.Can increase the outside cooling surface area of exhaust cavity like this, improve exhaust cavity heat transfer to external world, reduce delivery temperature.
The beneficial effects of the utility model are: by between air aspiration cavity and exhaust cavity air groove being set, can effectively reduce the air heat radiation of air in air aspiration cavity in the exhaust cavity, increase the fin density of exhaust cavity and exhaust cavity outer surface thereof simultaneously, so just increased the outside cooling surface area of exhaust cavity, strengthen exhaust cavity heat transfer to external world, reduce the exhaust cavity temperature.
Description of drawings
Fig. 1 is the utility model structural representation.
In conjunction with the accompanying drawings, make the following instructions:
1---air aspiration cavity 2---exhaust cavity
3---radiating fin 5---air groove
Embodiment
A kind of air-cooled reciprocating piston air compressor cylinder head comprises air aspiration cavity 1 and exhaust cavity 2, is equipped with radiating fin 3 on air aspiration cavity 1 and exhaust cavity 2 outer surfaces, is provided with air groove 5 between described air aspiration cavity 1 and the exhaust cavity 2.Because the thermal conductivity of air has only 0.02454W/m.k, and the thermal conductivity of grey cast iron commonly used is 39.2W/m.k, and both differ nearly 1600 times, therefore is provided with this air groove and can effectively reduces the air heat transfer of air in air aspiration cavity in the exhaust cavity.
Above-mentioned exhaust cavity 2 is bigger than the volume of air aspiration cavity 1.
Spacing between the radiating fin 3 on the gap ratio air aspiration cavity outer surface between the radiating fin 3 on the above-mentioned exhaust cavity outer surface is little.Can increase the outside cooling surface area of exhaust cavity like this, improve exhaust cavity heat transfer to external world, reduce delivery temperature.
