Embodiment
Referring to Fig. 1, Fig. 1 is the structural representation of the existing embodiment of wave filter one, the wave filter 100 includes shell
102, shell 102 is filtered exposed to the side of environmental surfaces coated with one layer of 80~140um polyester resin (not shown) with strengthening
The antiseptic property of device 100, such as 80 μm, 100 μm, 120 μm, 140 μm.When spraying polyester resin, it is necessary first to by wave filter
100 surface of shell 102 sprays again after being aoxidized, and in spraying process polyester resin easily ftracture or cover it is bad,
As long as the area failure for having a pinprick big can all cause the whole failure of wave filter 100 to be scrapped；On the other hand, due to polyester resin
Thermal conductivity factor it is low, the heat dispersion of wave filter 100 can be influenceed, therefore, as shown in figure 1, the surface of 100 shell of wave filter 102 is set
Count into the deep thin structure of radiation tooth 104 to increase the area of dissipation of wave filter 100, in Fig. 1 only signal identify one and dissipate
Hot tooth 104.But this make it that the mould in injection process of wave filter 100 is easy again with the deep thin structure design of radiation tooth 104
Cracking, die cast are difficult.
Fig. 2-Fig. 3 is referred to, Fig. 2 is the structural representation of the embodiment of the utility model wave filter one, and Fig. 3 is in Fig. 2
Filter flanks structural representation.The surface 202 that the wave filter 200 is externally exposed environment coats an oxidation film layer 204, at this
In embodiment, surface 202 is the surface of the shell 206 of wave filter 200, and the material on the surface 202 is aluminium, aluminium alloy, titanium, titanium conjunction
Gold, magnesium, magnesium alloy, surface aluminize or the steel substrate of calorize in it is any, the material of surface 202 is aluminium in the present embodiment；
Wherein, the thermal conductivity factor for coating the surface 202 after oxidation film layer 204 is more than 120W/mK；Thermal conductivity factor represents the heat transfer of material
Ability, it is directly proportional to heat-sinking capability.Therefore coated with the heat-sinking capability of wave filter 200 enhancing after the oxidation film layer 204.With coating
Material in polyester resin is compared, and the area of dissipation of its wave filter 200 relative can reduce 30%-40%.In actual application, such as
Shown in Fig. 1 and 2, it is assumed that in the case that the wave filter shown in Fig. 1 and Fig. 2 is all based on equivalent parameters condition, the utility model institute
The wave filter of offer can reduce the number of radiation tooth 208 according to actual conditions, expand the spacing between radiation tooth 208；Or

Titanium oxide layer；Specifically, filter housing is placed in and certain voltage is electrolysed and applied in the liquid solution containing element titanium,
Plasma micro-arc electric discharge is produced on filter housing surface using electrochemical method, in heat chemistry, plasma chemistry and electricity
In shell Surface Creation titanium oxide layer under the collective effect of chemistry.On the one hand using the oxidation prepared by the plasma method
Titanium film layer and case surface are metallurgical bindings, and bond strength is higher, thus occur the likelihood ratio of the situation that covering is bad, comes off compared with
It is low；On the other hand, in liquid phase environment, it can make it that bath composition is good with case surface contact, not by case surface shape
The limitation of shape size, the titanium oxide layer uniformity of formation are preferable.In addition, the titanium oxide layer formed using this method is outer
Layer is loose structure, and internal layer is compact texture, and as shown in fig. 4-5, wherein Fig. 4 is the scanning on surface after cladding titanium oxide layer
Electronic Speculum schematic diagram, Fig. 5 are the cross-sectional Transmission Electronic Speculum schematic diagram on surface after cladding titanium oxide layer.Figure 4, it is seen that the oxygen
It is loose structure to change titanium film layer to be externally exposed the side of environment, and the structure can store machine oil, wave filter is cold open during
Its lubricating ability is improved, reduces friction；From figure 5 it can be seen that the loose structure of oxidation titanium film layer surface is nonpenerative more
Pore structure, contacted with case surface (being in the present embodiment aluminium base) one layer of titanium oxide layer are compacted zone, and the layer can be with
Completely enclosed firmly case surface, and then improve the corrosion resistance of shell.
Table 1 is referred to below, and table 1 is to be carried out after oxidation film layer is wrapped up on the filter housing surface based on 7 kinds of unlike materials
The data of antiseptic property test.To make data result that there is comparativity, below 7 groups of embodiments be all based on ASTMB117 salt fogs survey
Test-object is accurate, and the thickness and method all same of the titanium oxide layer in shell surface spraying.
Table 1 carries out the number of antiseptic property test after the filter housing surface parcel oxidation film layer based on 7 kinds of unlike materials
