Abstract
The invention discloses a lightweight housing of a compressor of a refrigerator. The lightweight housing is characterized in that the housing is an Mg-Al-Li magnesium alloy housing which is prepared by feeding Mn, Al and Li to pure magnesium and then performing laser surface alloying; a protecting film is added to the surface of the housing, and the protecting film is characterized in that an epoxy anticorrosive coating is used and forms an organic substance coat on the housing surface. According to the lightweight housing of the compressor of the refrigerator, the magnesium alloy material is used, so that the housing is light in weight, high in heat transferring and electric conducting performances, high in welding performance, fast to dissipate heat, low in density, and high in strength; in addition, the anticorrosion organic coat is formed on the outer surface, so that the housing is outstanding in corrosion resistance; the housing has a good application prospect in the field of electric appliance.
Description
Technical field
The present invention relates to appliance field, particularly relate to a kind of lightweight freezer compressor shell.
Background technique
Lightweight material is a kind of advanced composite material (ACM), it does to strengthen material with alkali-resistant glass fibre, aluminium sulfate low alkalinity cement is agglutination material and mixes to be suitable for the formation base material that gathers materials, by spraying, formwork erection casts, extrude, flow the inorganic composite material that the techniques such as slurry make, to replace stone, sand etc., can weight reduction greatly.
Magnesium alloy take magnesium as the alloy that base adds other elements composition.Be characterized in: density little (about 1.8g/cm3 magnesium alloy), specific strength is high, larger than Young's modulus, good heat dissipation, and shock absorbing is good, and the load-carrying ability that withstands shocks is larger than aluminum alloy, and the corrosivity of resistance to organic substance and alkali is good.Main alloy element has aluminium, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium etc.What current use was the widest is magnalium, is secondly magnesium-manganese alloy and magnesium zinc zircaloy.Be mainly used in the industrial departments such as Aeronautics and Astronautics, transport, chemical industry, rocket.Be the lightest metal in practical metal, the proportion of magnesium is approximately 2/3 of aluminium, is 1/4 of iron.It is the lightest metal in practical metal, high strength, high rigidity.
Summary of the invention
The technical problem that the present invention mainly solves is to provide one, and can have good heat-conductivity conducting, good welding performance, material is slim and graceful.
The technological scheme that the present invention adopts is: provide a kind of lightweight freezer compressor shell; it is characterized in that; described lightweight freezer compressor shell is a kind of Mg-Al-Li series magnesium alloy housing; described Mg-Al-Li series magnesium alloy housing forms through laser surface alloying processing by adding Mn, Al and Li in pure magnesium; described lightweight freezer compressor case surface with the addition of protective film, and described protective film adopts anti-corrosive paint of epoxy resin to carry out organic substance coating to surface of shell.
Further, described lightweight freezer compressor outer casing thickness is greatly about 3mm ~ 4.5mm.
Further, in described Mg-Al-Li series magnesium alloy housing, the percentage of element is as follows: 40-45%Mg, 10-25%Al, 25-35%Li.
The invention has the beneficial effects as follows: a kind of lightweight freezer compressor of the present invention shell adopts magnesium alloy material light weight to be full of, heat-conductivity conducting performance is good, good welding performance, rapid heat dissipation, density is little, intensity is high, and the anticorrosion organic coating of surface smear one deck makes housing have good corrosion resistance outside in addition, has a good application prospect at appliance field.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
A kind of lightweight freezer compressor shell, it is characterized in that, described lightweight freezer compressor shell is a kind of Mg-Al-Li series magnesium alloy housing, described outer casing thickness is greatly about 3mm ~ 4.5mm, magnesium alloy proportion belongs to most the lighter in all structure alloys, density is little, specific strength is high, the load-carrying ability that withstands shocks is all larger than general alloy, described Mg-Al-Li series magnesium alloy housing adds Mn by pure magnesium, Al and Li forms through laser surface alloying processing, described laser surface alloying process mainly utilizes laser irradiation source and material to interact, at Mg alloy surface generation physical and chemical changes, make pure magnesium and alloying element melt-blended, form new surface alloying layer, in housing, the percentage of element is as follows: 40-45%Mg, 10-25%Al, 25-35%Li, described lightweight freezer compressor case surface with the addition of protective film, described protective film adopts anti-corrosive paint of epoxy resin to carry out organic substance coating to surface of shell, described anti-corrosive paint of epoxy resin take epoxy resin as film forming matter, add a certain amount of pigment, filler, auxiliary agent, solvent etc. are formulated, good anti-corrosion protection effect is played to housing.
A kind of lightweight freezer compressor of the present invention shell adopts magnesium alloy material light weight to be full of, heat-conductivity conducting performance is good, good welding performance, rapid heat dissipation, density is little, intensity is high, and the anticorrosion organic coating of surface smear one deck makes housing have good corrosion resistance outside in addition, has a good application prospect at appliance field.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
