Hot jacket two is fixedly connected with the eccentric shaft.It is cased with radiating sleeve two on the outside of eccentric shaft, there is preferable heat dissipation to imitate eccentric shaft
Fruit improves service life.
In the bent axle of above-mentioned freezer compressor, the lateral wall of the radiating sleeve is equipped with several heat dissipation grooves and described
Heat dissipation groove be uniformly distributed along the axial direction of the radiating sleeve.The lateral wall of radiating sleeve is equipped with heat dissipation groove, improves scattered
Hot jacket heat dissipation area has preferable heat dissipation effect.
In the bent axle of above-mentioned freezer compressor, lateral bending folding is fixedly connected with axis body inside for one end of the radiating sleeve.
Using above-mentioned setting, make radiating sleeve that there is preferable connection effect with axis body.
In the bent axle of above-mentioned freezer compressor, the radiating sleeve is used using aluminium alloy and is made.Radiating sleeve uses
Aluminium alloy is made, and has the advantages that the preferable lighter in weight of heat dissipation effect.
In the bent axle of above-mentioned freezer compressor, the radiating sleeve is made of copper.
In the bent axle of above-mentioned freezer compressor, lateral bending folding and axis body are mutually solid inside for the other end of the radiating sleeve
Even.Using above-mentioned setting, the advantage for keeping the connection effect of radiating sleeve and axis body preferable.
Compared with prior art, the bent axle of this freezer compressor has the following advantages：
1, since radiating sleeve is arranged and be fixed on axis body, there is preferable heat dissipation effect to the axis body of this bent axle, due to
Radiating sleeve is made of metal material, and has the advantages that heat dissipation effect is preferable and service life is longer；
2, radiating sleeve is connected on axis body by lock-screw, preferable with locating effect and relatively simple structure is excellent
Point；
3, radiating sleeve is made of aluminium alloy, has the advantages that the preferable lighter in weight of heat dissipation effect.
