Description
Technical field
The present invention relates to the housing of refrigeration compressor, specifically the housing of the high-cooling property refrigeration compressor of the chiller plants such as totally enclosed type refrigerator, refrigerator.
Background technique
The compressor housing of the chiller plants such as existing totally enclosed type refrigerator, refrigerator, its inner and outer surface is level and smooth surface, with thermal conductivity preferably plane steel plate be stamped to form, its heat dispersion can meet design requirement.But to further promote the heat dispersion of housing, make the compressor inside temperature lower just relatively more difficult.Nowadays, along with the lifting of product performance, require the heat dispersion of housing better, and will reach better thermal diffusivity, in the identical situation of material, just need to be to the structure redesign of housing.In addition, aspect vibration control, structural energy of deformation suppresses the vibration of housing.
Summary of the invention
Purpose of the present invention is improved existing refrigerant compressor housing surface structure exactly, provides a kind of heat dispersion better, is more conducive to simultaneously the high-cooling property refrigerant compressor housing of casing vibration control.
Main structure of the present invention is identical, and improvement part is divided into following three kinds of technological schemes:
Scheme one: the high-cooling property refrigerant compressor housing, described housing comprises loam cake and lower casing, improvement is: be processed with several projections at described loam cake and lower casing internal surface or outer surface.
Described projection be mound shape, column, taper or trapezoidal in a kind of, on the uniform or non-all or part of internal surface or outer surface that is distributed in loam cake and lower casing.
Scheme two: high-cooling property refrigerant compressor housing, described housing comprises loam cake and lower casing, improvement is: at described loam cake and lower casing surface Machining structure recessed outside the convex or the indent evagination is arranged, this structure consists of waveform or striated or mound shape at loam cake and lower casing surface.
Uniform or non-loam cake and lower casing all surfaces or the part surface of being distributed in of described wave or striated or mound shape structure, the consistency of thickness of its convex-concave place thickness and loam cake and lower casing itself.
Scheme three: the high-cooling property refrigerant compressor housing, described housing comprises loam cake and lower casing, improvement is: be processed with some fin structures at described loam cake and lower casing outer surface.
Described fin structure is cuboid shape or fin-shaped, uniform or non-loam cake and all or part of outer surface of lower casing of being distributed in.
Described fin thickness 1-2mm, the height 8-10mm, between each fin apart from 3-6mm.
In the such scheme one, it is long-pending that protruding structure can increase surface of shell, improves the housing thermal diffusivity; Also can improve casing rigidity in addition, suppress the housing transmitting vibrations; The size of its each projection, spacing and height are determined according to the housing profile, also can determine according to performance need; Projection can with Surface Vertical, also can have a certain degree with the surface, protruding structure can make the housing heat diffusion area be multiplied, thereby heat dispersion is greatly improved, distribute more heat in unit time, play the effect of fast cooling, make the compressor operating temperature lower.Add man-hour, available mould secondary is processed, or is welded on surface of shell with the direct one by one projection of the mode of welding.
In the such scheme two, convex outward recessed or indent evagination makes surperficial waveform or stripe-shaped or the mound shape structure that forms; This structure has not only strengthened the intensity of housing, the amplitude that the active force of formed objects evokes hull vibration can decrease, when vibration with vibration source point during to ambient radiation, because the existence of convex-concave structure, destroyed the path of particle along the smoothed curve propagation, restrain the kinetic energy that vibrates in the particle propagation process, the propagation of sound is outwards propagated with the vibration of particle just, and this structure just in time can suppress the vibration of particle; In addition, after on the housing convex-concave structure being arranged, the number of curved surface has increased a lot, when sound was propagated in housing, through reflection or the refraction of these faces, part acoustic energy was cancelled out each other in this process, effect by this two aspect, the vibration of housing is inhibited, and acoustic energy decreases, and therefore vibration and noise reducing is had preferably effect; Heat dispersion raising aspect, convex-concave structure makes the surface of housing obtain extending, total body surface area obtains increasing, and scattering and disappearing of heat is directly proportional with area, and area is larger, the heat that distributes in unit time is more, sunk structure wherein can also be collected the moisture that refrigerator is discharged, and is collected into the moisture above the housing, by the compressor heating evaporation, in evaporation process, simultaneously the heat of compressor is taken away, can be played cooling effect to compressor.
The formation of waveform or stripe-shaped or mound shape structure, to design according to Vibration Condition, the perpendicular direction of its direction and vibration of compressor direction maximum, such design can make the vibration of particle not smooth, because the existence of trough and crest is arranged, particle will be with the vibration going down, must pass through these troughs or crest, the total direction of vibration of particle is along the housing tangent direction on trough or the crest, and in front particle to drive both directions of vibration of particle on trough or the crest different, the direction of vibration of trough or crest particle is the component of its vibration, therefore when vibration was down transmitted, the vibration of particle was slowly suppressed, has played so good effectiveness in vibration suppression, also control simultaneously the transmission of noise, therefore vibration and noise reducing has been had preferably effect.In addition, the housing on originally similar plane, behind the increase lines, its surface area also increases, and scattering and disappearing of heat is directly proportional with area, and area is larger, and the heat that distributes in the unit time is more, can better play the effect of heat radiation.
More than three class formation housings make concrete grammar dual mode arranged, one, at first on the housing raw material with the shaping structures of needs.First stamp out pit at housing sheet material, the pit size determines that according to the design needs pit rate is determined according to heat dispersion; After the materials processing of making housing was good, the placement of material was determined by structure species, makes housing according to housing mould again; Its two, make first housing, according to the housing stamping die, case material is made into common housing, according to designing requirement, if need waveform or stripe-shaped or mound shape structure, make the mould of corresponding construction, by punching press, the housing of moulding Structure of need gets final product.
In the such scheme three, because the fin structure of design greatly improves heat dispersion.Because in the heat radiation process, can dispel the heat to air in the two sides of fin, so in onesize space, heat diffusion area increases with multiple, in addition, surface of shell increases fin, and heat diffusion area increases several times than original heat diffusion area.Comprehensive above two aspects, the housing heat diffusion area obtains very large raising, and heat dissipating capacity is directly proportional with heat diffusion area, and after fin housing heat diffusion area increased, unit time inner housing heat dissipating capacity also increased thereupon, and the temperature during compressor operating is lower.
The fin structure making method has two kinds, and one is produced common housing according to normal process first, again fin is bonded on surface of shell by techniques such as welding, forms this structure housing; Its two, directly form this structure housing by techniques such as die casting, cast and castings.
Certainly, in the situation that principle of the present invention remains unchanged, the detail of structure and form and size and position, shape and direction can be different from the described form of this specification, all do not break away from protection scope of the present invention.
