Embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As depicted in figs. 1 and 2, embodiment one compression cylinder cylinder body has rotor receiving opening 11 and deviates from mutually the first end face 12 of setting, outer circumferential face and the inner peripheral surface of the second end face between the first end face 12 and the second end face, in the wall of compression cylinder cylinder body, be provided with insulation hole 13, in insulation hole 13, be filled with thermal barrier 20.In the wall of compression cylinder cylinder body, refer to the part between outer circumferential face and inner peripheral surface.Preferably, insulation hole 13 is arranged on the first end face 12.
The compression cylinder cylinder body of application the present embodiment, in wall due to compression cylinder cylinder body, be provided with insulation hole 13, and in insulation hole 13, be filled with thermal barrier 20, therefore, the heat of compression cylinder cylinder body outside substantially can be stopped by thermal barrier 20, avoid heat to be delivered to rotor receiving opening 11, namely in compression chamber in the time of radially the moving to rotor receiving opening 11 of compressed cylinder cylinder body, can reduce the temperature of compression chamber, and finally improve refrigerating capacity.As the above analysis, the compression cylinder cylinder body of the present embodiment can reduce the temperature in compression chamber in the situation that of the normal work of compression cylinder.In addition, because thermal barrier 20 is arranged in insulation hole 13, therefore insulation hole 13 plays a protective role to thermal barrier 20, avoids thermal barrier 20 impaired.
Suppose that existing cylinder is single layer structure thermal resistance: R1=δ 1/ λ 1 (m2.K/w); In examination: δ 1-cylinder thickness (m); λ 1-cylinder thermal conductivity [W/ (m.k)]; Adopt technical solutions of the utility model, increase after thermal barrier, cylinder is multi-layer structure thermal resistance: R2=δ 1/ λ 1+ δ 2/ λ 2; In examination: δ 2, λ 2 are respectively thickness and the thermal conductivity of thermal barrier.Because thermal barrier thermal conductivity is low, it is only 1/6 left and right of metal.R2 " R1, thermal resistance significantly increases, and significantly reduces cylinder heat transfer efficiency.Thereby improve refrigerating capacity and reduce power consumpiton.
As shown in Figure 2, in embodiment one, insulation hole 13 in the footpath of rotor receiving opening 11 overall dimensions be upwards less than this insulation hole 13 perpendicular to this rotor receiving opening 11 radially and perpendicular to the overall dimensions in the axial direction of this rotor receiving opening 11, that is to say, insulation hole 13 is along the long strip radially extending perpendicular to rotor receiving opening 11 on the cross section of the axis perpendicular to rotor receiving opening 11.So better trap heat.In Fig. 2, insulation hole 13 is rectangle on the cross section of the axis perpendicular to rotor receiving opening 11, and this insulation hole extends in the direction radially perpendicular to rotor receiving opening 11.
As shown in Figure 2, in embodiment one, insulation hole 13 is rectangle on the cross section of the axis perpendicular to rotor receiving opening 11.As feasible mode of execution, insulation hole 13 also can be triangular in shape on the cross section of the axis perpendicular to rotor receiving opening 11.
As shown in Figure 2, in embodiment one, insulation hole 13 is multiple, and multiple insulation holes 13 upwards arranged at interval in the week of compression cylinder cylinder body.
As shown in Figure 2, in embodiment one, each insulation hole 13 center equates to the distance of the axis of rotor receiving opening 11.Adopt said structure, each insulation hole 13 on same annulus, can play better heat-blocking action substantially.
As shown in Figure 2, in embodiment one, insulation hole 13 is through hole.Like this, the distance of thermal barrier 20 and the first end face 12 to second end faces is suitable, can play better heat-blocking action.
As depicted in figs. 1 and 2, in embodiment one, thermal barrier 20 is ceramic plate.Ceramic plate is convenient to insert in insulation hole 13, and the thickness of ceramic plate is 2-8mm.The shape of the profile of ceramic plate and insulation hole 13 is suitable.
As shown in Figure 3, embodiment two compression cylinder cylinder body and the difference of above-described embodiment one be, insulation hole 13 is the circular arc taking rotor receiving opening 11 center as the center of circle on the cross section of the axis perpendicular to rotor receiving opening 11.The rotor receiving opening 11 of circular arc can better adapt to the shape of compression cylinder cylinder body, and reduces the area upwards not covered by rotor receiving opening 11 in week of compression cylinder cylinder body, has further improved effect of heat insulation.
Embodiment three compression cylinder cylinder body (not shown) is that with the difference of above-described embodiment one insulation hole 13 is for annular blind hole.The week of compression cylinder cylinder body is upwards all covered by rotor receiving opening 11, has improved effect of heat insulation.
The application also provides a kind of compressor (not shown), and the compressor of the present embodiment comprises compression cylinder cylinder body, the compression cylinder cylinder body that compression cylinder cylinder body is above-mentioned arbitrary embodiment.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
