It is properly located electric device inside the cover.
Fig. 2 a and Fig. 2 b show the second preferred forms of cover according to the present utility model.The second form of the utility model
200 all essential features with form shown in Fig. 1 a and Fig. 1 b, but the difference is that, the heat dissipation of side wall 206,207
Under piece 204,205 is directed toward.Cooling fin 204,205 tilts down the row under the effect of gravity for realizing the impurity at their surfaces
Go out.When cover 200 is positioned near potential pollution source and/or when air stream is filtered before touching the cover, this
It is especially important.
Fig. 3 a and Fig. 3 b show the third preferred form of cover according to the present utility model.The third form of the utility model
300 all essential features with form shown in Fig. 1 a and Fig. 1 b and Fig. 2 a and Fig. 2 b, but the difference is that, side wall
306,307 cooling fin 304,305 has alternately different length.Alternately on element of the different length by eliminating mold
Stress facilitate cover production technology, and make it possible to obtain cooling surface appropriate.
In addition, can be equipped with installation passage 108,208,308 according to the utility model of the application, the installation is logical
Road 108,208,308 allows protecgulum to be mounted on cover, such as uses screw.Lid can also be otherwise installed, it is such as logical
Cross latch.The arrangement of installation passage 108,208,308 is only one embodiment shown in Fig. 1 a- Fig. 3 b.They can basis
It needs to be disposed on the circumference of cover 100,200,300.
In the form of the utility model presented in figure, the cooling fin of side wall 106,107,206,207,306,307
104,105,204,205,304,305 cooling fin 103,203,303 for being longer than lower part wall 102,202,302.However, described dissipate
Backing can with equal length or lower part wall 102,202,302 cooling fin 103,203,303 be longer than side wall 106,
107,206,207,306,307 cooling fin 104,105,204,205,304,305 is grown.Described length depends in cover
