Abstract
A compressor shell with a wavy structure and a method for processing the same are provided, wherein, the compressor shell with a wavy structure is of a cylindrical structure; a plurality of grooves which are equidistantly distributed and parallel to an axle wire of an electrical motor are arranged on the inner wall of the compressor shell; ribs which have the same quantity as that of the grooves, protrude outwards and are parallel to the axle wire of the electrical motor are arranged on the outer wall of the compressor shell corresponding to the grooves. The processing method includes the following steps of: first stamping a flat slab used to make the compressor shell according to design requirements to make the flat slab with one side provided with a plurality of grooves and the other side provided with ribs corresponding to the grooves; then curling the flat slab into a cylindrical shape and finally making the compressor shell by welding. As the grooves are shaped on the inner wall of the shell, the grooves which are used as the passage for cooling media can be made wider and deeper, while the ribs shaped on the outer wall of the shell enlarge the radiating area of the shell, which is in favor of the circulation of the cooling media and the cooling of a stator. The motor stator of the invention is unprocessed, thereby saving processing cost, fully guaranteeing magnetic conductivity of the stator and improving the efficiency of the electrical motor and the compressor.
Description
Technical field
The present invention relates to a kind of compressor housing and processing method thereof.
Background technique
Compressor is a kind ofly with mechanical energy gas compression to be become the device of pressurized gas, and it generally can be divided into various ways such as reciprocating type, eddy type, blade type.In order to make full use of energy, prevent or reduce refrigerant issuable leakage in compression process, its compressing mechanism and all be installed in hermetically in the same compressor housing as the drive motor of compression power.
Existing scroll compressor as shown in Figure 1 is made of casing 1, the main frame 2, auxiliary frame (not shown), drive motor 3, live axle 4, Moving plate 5, static vortex disk 6, high low pressure dividing plate 7 and the one-way valve 8 that are contained in the casing, sucking pipe SP and outlet pipe DP are installed on the casing 1, and main frame 2 and auxiliary frame are installed in the both sides up and down of casing 1 inner peripheral surface respectively; Live axle 4 is installed in the center of drive motor 3 and passes main frame 2 and transmit the power of motor 3, and Moving plate 5 links to each other with live axle 4 and is positioned at the end face of main frame 2; Static vortex disk 6 is fixed on the main frame 2 and with Moving plate 5 and joins, its inner several pressing chambers that form; Dividing plate 7 links to each other with the end face of static vortex disk 6 and casing 1 inside is divided into compressing area and exhaust area; The reed 8b of one-way valve 8 can make pressurized gas discharge and can prevent to discharge the backflow of gas to the hole 6b open and close on the static vortex disk 6.
Shown in Fig. 2 A, 2B, the housing 1 of above-mentioned existing compressor is cylindrical, and the motor stator core 31 that sets within it, its center is provided with rotor and the groove 311 that bursts at the seams on the stator iron core 31 is filled by heart yearn, in order to guarantee that refrigerant has certain passage, so on the outer circumferential face of the stator iron core 31 of drive motor 3, offer a plurality of vent grooves 311 that parallel with the motor center axis.This way not only difficulty of processing is big, and cost rises, and can reduce because of core section, and the motor stator permeability reduces and electric efficiency is descended.
Summary of the invention
Technical problem underlying to be solved by this invention is, it is not good enough with the unreasonable motor stator cooling effect that cause of stator on cooperating of drive motor to overcome existing compressor case, defective with the electric efficiency decline that causes because of the decline of stator permeability, and a kind of compressor housing and processing method thereof that can be applicable to the Wave-shaped structural of all closed rotary compressors is provided, to overcome the shortcoming that the motor cooling effect is bad and electric efficiency descends.
The compressor housing of Wave-shaped structural of the present invention is:
A kind of compressor housing of Wave-shaped structural, become columnar structured, it is characterized in that: described compressor housing, inner wall surface thereof is provided with several and becomes vent grooves equidistantly that distribute, that be parallel to the motor medial axis, and its with the corresponding outer wall of above-mentioned vent grooves on be provided with several fin outside protrusion, that be parallel to the motor medial axis on an equal basis; Described vent grooves, its position and the motor stator mounting point in casing is suitable, and its length is greater than the height of motor stator.
The processing method of the compressor housing of Wave-shaped structural of the present invention is:
A kind of processing method of compressor housing of Wave-shaped structural, it is characterized in that, the flat board that is used for making compressor housing is carried out punching press by designing requirement, the formation inner face has several grooves and the sheet material of outside formation and the corresponding equal number fin of groove location, and then is curled into tubular and is welded into compression case.
The invention has the beneficial effects as follows, because above-mentioned groove takes shape in shell inner surface, can with open as the groove of refrigerant passage broad, darker, and the fin that takes shape in housing outer surface has increased the heat diffusion area of casing, help the circulation of refrigerant and the motor stator among cooling, especially the present invention of stator is not processed, this has not only saved processing charges, fully guarantee the permeability of stator, thereby improved electric efficiency and compressor efficiency.
