In heat abstractor of the present invention, described fan 100 is connected with the fixing of loading plate 200, it is to fix in the way of hot melt between fixed part 1232 and connecting portion 220, eliminate fan 100 and adopt, with loading plate 200, the screw cost being screwed and produce, make in the present invention the fixing not only good stability of hot melt between fan 100 and loading plate 200 but also with low cost, be conducive to producing in batches.Described fan lid 30 and loading plate 200 use the absolute construction of non-integral so that fan lid 30 and the independent molding of loading plate 200, reduce further the manufacturing cost of heat abstractor.
The present invention also provides for the assemble method of a kind of heat abstractor described above, and its step is as follows:
Step one: as shown in Figure 6 a, it is provided that fan frame 10.Described fan frame 10 include base plate 11, from base plate 11 periphery upwards one elongation moulding side plate 12, described side plate 12 is formed a supporting part 123.The two ends of described supporting part 123 upper surface upwards protrude out and are formed with two grades and meet portion 123a and at two grades of two projection 123b connect between portion 123a.
Please also refer to Fig. 7, described projection 123b is the cylinder of hollow, has cavity 1230 inside it.Described projection 123b includes that a main part 1231 and main body 1231 top upwardly extend and in the location division 1233 gradually tapered up.Described main part 1231 size uniform everywhere, the size of described location division 1233 is certainly connected one end with main part 1231 and starts to be gradually reduced.Described location division 1233 includes an end face 1233a, tilts the auxiliary section 1233b extended from end face 1233a towards cavity 1230, and tilts to extend and connected to the outer surface 1233c of described main part 1231 tip edge from end face 1233a.
Step 2: as shown in Figure 8 a, it is provided that loading plate 200, described loading plate 200 one end stretches out and is formed with a junction 220, described connecting portion 220 is formed with through hole 221.The size of described through hole 221 size more than or equal to described location division 1233 and the size less than described main part 1231.Described loading plate 200 is a plate body being made up of aluminum.
Step 3: such as Fig. 9, it is provided that a kind of thermofusion device 300.Described thermofusion device 300 includes the ennation 320 that a main body 310 and autonomous agent 310 end face extend vertically upwards.Described ennation 320 farther includes end face 321, and described end face 321 offers groove 322.
Described groove 322 bottom surface upwards protrudes out and is formed with hot melt head 323, and described hot melt head 323 includes one first service portion 3231 and the second service portion 3232 upwardly extended from the first service portion 3231 top vertical and encloses and be located at the second service portion 3232 and the first joint face 3230 of the first service portion 3231 junction.
Described first service portion 3231 arcwall face, it is towards the cambered surface upwards protruded out in the middle part of groove 322 from groove 322 edge.Described second service portion 3232 is column, and it includes an end face 3233, sidewall 3234 and connects the second joint face 3235 of described end face 3233 and sidewall 3234.Described end face the 3233, second joint face 3235 coordinates described auxiliary section 1233b and in beneficially hot melt head 323 is pressed into described projection 123b.
Step 4: as shown in figs. 10-11, utilizes thermofusion device 300 that with loading plate 200, fan 100 is carried out hot melt and fixes.
When described fan 100 is fixed with loading plate 200 hot melt, the through hole 221 on described connecting portion 220 docks with the location division 1233 on projection 123b, and the location division 1233 of projection 123b penetrates through hole 221.Subsequently thermofusion device 300 is pressed in projection 123b along the cavity 1230 of projection 123b, first service portion 3231 of described hot melt head 323 and the second service portion 3232 are pressure bonded to the location division 1233 of projection 123b, and described location division 1233 turns to groove 322 outward at high temperature hot melt and under described first service portion 3231 effect
In, thus between the main part 1231 of described connecting portion 220 and described projection 123b, form a hot melt fixed part 1232.
Described hot melt fixed part 1232 turns up towards connecting portion 220 from the main part 1231 of described projection 123b and covers described through hole 221 edge.Described fixed part 1232 includes 1232a bottom, top 1232b, tilts the inwall 1232c extended from top 1232b towards cavity 1230 periphery, and extends the arc outer wall 1232d formed towards 1232a edge, bottom from top 1232b.Described inwall 1232c is the surface of similar inclination, and described outer wall 1232d is similar arcwall face.Connecting portion 220 is fixed by described fixed part 1232 with described projection 123b, prevents connecting portion 220 from separating with supporting part 123, and then makes to be fixed between loading plate 200 and fan 100 well.
