Description

Compressor crankcase
Technical field
The present invention relates to compressor fields, more specifically, it is related to a kind of compressor crankcase.
Background technique
Compressor of air conditioner is to play compressible drive refrigerant in air conditioning coolant loop.Compressor of air conditioner generally fills In outdoor unit.Refrigerant is sent to the cooling condensation in higher-pressure region from low-pressure area extraction by compressor of air conditioner after compression, by dissipating Backing gives out heat into air, and refrigerant also becomes liquid, pressure rise from gaseous state.Compressor is former by gas pressure is improved Reason is divided into positive displacement and speed mode, has a kind of piston compressor in positive displacement, is the one kind being frequently used now, in piston Essential in formula compressor is exactly crankshaft, and crankshaft is the power-transmitting part of piston compressor.Motor etc. is external dynamic Power transfers power to compressor by crankshaft, and crankshaft drives another compressor part -- connecting rod mounted thereto, Reciprocating motion is converted by rotary motion, to realize the work of piston compressor.And crankshaft is typically required and is mounted on crankshaft It inside case, but with the continuous mobile of crankshaft and rubs, the temperature and noise inside crankcase can all improve, this pressure that can make Contracting machine generates a large amount of noises at work and generates the phenomenon that temperature increases, and not only influences the health of user, but will be due to temperature The raising of degree causes the Frotteurism between part to change, so that the reduced service life of compressor.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of compressor crankcase, pass through The water-cooling channel being provided with inside cabinet wall so that crankshaft noise for generating when box house moves it is less be transmitted to it is outer Boundary, and by making the water circulation inside water-cooling channel, the heat generated when by Crankshaft motion is discharged to the external world.
To achieve the above object, the present invention provides the following technical scheme that a kind of compressor crankcase, including cabinet, Installing port is offered on the side wall of the cabinet, there are two installing ports, the axis of two installing ports perpendicular to cabinet axis and It is obliquely installed, the interior of cabinet offers water-cooling channel, offers along its cross-section radial by water cooling on the lateral wall of cabinet The inlet opening that channel is in communication with the outside offers on the lateral wall of cabinet along its cross-section radial and water-cooling channel is in communication with the outside Apopore, the axis of inlet opening and the axis of apopore are orthogonal and coplanar, and inlet opening and apopore are provided with cabinet respectively Lower sides on.
By using above-mentioned technical proposal, sound is as caused by object vibration, and crankshaft is bent when box house moves Axis and cabinet wall can all generate vibration, and the energy that this vibration generates can successively pass through cabinet wall, inside water-cooling channel Water flow, cabinet exterior and be transmitted to the external world, vibration generate energy pass through different medium when can be lossy, so by Box house, which offers, to be loaded with the water-cooling channel of water and can reduce the noise generated when Crankshaft motion.It is sent out when Crankshaft motion simultaneously The recirculated water that raw friction and the heat generated can be water cooled channel interior is absorbed, and the phenomenon that cabinet generates heat is weakened.
Preferable: the radial direction on the side wall of the cabinet along its section is provided with inlet channel, and the two of inlet channel End is located at the inside and outside of cabinet side side wall, and box house cavity is in communication with the outside by inlet channel, the air inlet The middle part in channel is located inside water-cooling channel.
By using above-mentioned technical proposal, by the way that inlet channel to be located inside water-cooling channel, gas and case can be reduced The heat transfer that body and inlet channel friction generate is to outside cabinet or concentrating on the possibility of box house, while gas flowing The noise of generation can be also weakened after the recirculated water and cabinet exterior inside cabinet wall, water-cooling channel, be reached The purpose of noise reduction and cooling.
Preferable: the radial direction on the side wall of the cabinet along its section is provided with outlet passageway, and the two of outlet passageway End is located at the inside and outside of cabinet side side wall, and box house cavity is in communication with the outside by outlet passageway, the outlet The middle part in channel is located inside water-cooling channel, and the inlet channel is located on the cabinet below two installing ports.
By using above-mentioned technical proposal, by the way that outlet passageway to be located inside water-cooling channel, gas and case can be reduced The heat transfer that body and outlet passageway friction generate is to outside cabinet or concentrating on the possibility of box house, while gas flowing The noise of generation can be also weakened after the recirculated water and cabinet exterior inside cabinet wall, water-cooling channel, be reached The purpose of noise reduction and cooling.
It is preferable: end cap, the cabinet and the end cap junction have been bolted on an end face of the cabinet Cricoid seal groove is offered on inner wall, and the installation with seal groove cooperation is offered on the end cap and the side wall of cabinet face Platform, when the side wall of end cap face cabinet is abutted with the end face of cabinet face end cap, erecting bed is plugged on inside seal groove, and is installed The side wall of platform is abutted with the side wall of seal groove.
By using above-mentioned technical proposal, can be enhanced by seal groove and erecting bed closed between end cap and cabinet Property, reduce the crankshaft possibility that box house air pressure outwardly leaks during exercise, ensure that the stability of compressor operating.
It is preferable: to be uniformly installed with multiple mounting blocks along the axial length direction of cabinet inside the water-cooling channel, pacify It is circumferentially distributed to fill block, the threaded hole being arranged along its length is offered inside the mounting blocks, screw thread connects on the end cap It is connected to the fixing bolt with threaded hole cooperation, also offers threaded hole respectively on the cabinet at the both ends of the water-cooling channel.
By using above-mentioned technical proposal, by being uniformly distributed circumferentially mounting blocks, can make between end cap and cabinet Bonding strength everywhere is more uniform, and bolt can be made to be connected to end cap is more stable on cabinet, further decrease crankshaft The possibility that box house air pressure change outwardly leaks when movement ensure that stability when compressor operating.
It is preferable: lead-over groove to be offered inside the wall box between two installing ports, lead-over groove and two installing ports connect Offer inlet and outlet at the position connect respectively, the axis of water inlet and apopore is each perpendicular to the axis of cabinet and not It is in the same plane.
By using above-mentioned technical proposal, pass through lead-over groove and the inlet and outlet being provided on lead-over groove, energy It is enough to connect the cylinder that two are mounted on installing port, so that the cooling water of a cylinder interior is by wall box Next cylinder interior is flowed into again after portion, and the water flow inside lead-over groove can provide certain noise reduction and cooling effect also for cabinet Fruit, simultaneously because the axis of water inlet and apopore is each perpendicular to the axis of cabinet and not in the same plane, so water flow Can more it be present in inside lead-over groove.
In conclusion the present invention is had the advantages that compared with the prior art 1. by being provided in cabinet wall The water-cooling channel in portion, so that the noise that generates is less when box house moves is transmitted to the external world for crankshaft, and by making water cooling The water circulation of channel interior, the heat generated when by Crankshaft motion are discharged to the external world.
