Fin combination and heat pipe combined improved structure

Technical field:

The utility model relates to radiating device technical field, refers in particular to the combining structure of a kind of groups of fins and heat pipe.

Technical background:

The existing integrated structure that is applied to fin and heat pipe is No. 491517 Taiwan patent application just like notification number, and its structure as shown in Figure 11; Be equipped with a sleeve joint hole 61a with socket heat pipe 62a on fin 60a, and be equipped with the less pore 63a of a bore in the peritreme of this

sleeve joint hole

61a, 64a penetrates for bonding jumper; Make bonding jumper 64a fusion and flow between heat pipe 62a and sleeve joint hole 61a by hot melting mode.

It is M263550 number Taiwan patent application that notification number is arranged in addition, and its structure is shown in accompanying drawing 12 to 14; See Figure 12, on fin 60b, be equipped with sleeve joint hole 61b, and establish an accommodation aperture 63b to incision, can flow between sleeve joint hole 61b and heat pipe 62b with ccontaining Heat Conduction Material 64b from the upper limb of fin 60b; Perhaps shown in Figure 13,14, can above fin 60c, 60d, be equipped with perforation 63c, 63d, with ccontaining 64c, 64d; Same, after heat fused, Heat Conduction Material 64c, 64d are flow between heat pipe 62c, 62d and sleeve joint hole 61c, 61d solidify, with in conjunction with this heat pipe 62c, 62d and fin 60c, 60d.

In addition as shown in Figure 15, this existing fin 60e establishes a storage tank 63e from top edge to incision, and this storage tank 63e is communicated with its socket cave 61e; When assembling, by dielectric object 64e such as the ccontaining tin bars of storage tank 63e; After implementing the heating fusion, this dielectric object 64e can flow between this heat pipe 62e and sleeve joint hole 61e and solidify.

Existing five kinds of structures shown in above-mentioned Figure 11 to 15, though can be effectively in conjunction with heat pipe in fin; But, but must on fin, remove the area of a part with accommodation aperture 63b, the perforation 63c of Figure 13 and 14 of pore 63a, Figure 12 of formation Figure 11 and the storage tank 63e of 63d and Figure 15 with cutting way; Therefore, reduced the area of dissipation of original fin, radiating efficiency is reduced.

The utility model content:
