Fig. 1 is the structural representation of the utility model first execution mode fin;
Fig. 2 is the front view of the utility model first execution mode fin;
Fig. 3 is the structural representation of the utility model second execution mode fin;
Fig. 4 is the front view of the utility model second execution mode fin.
Embodiment
Below will combine embodiment shown in the drawings that the utility model is described in detail.But these execution modes do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these execution modes, method or the function all is included in the protection range of the utility model.
In addition, in different execution modes, possibly use the label or the sign of repetition.These repeat to be merely simply clearly narrates the utility model, does not represent between the different execution modes discussed and/or the structure to have any relevance.
Join Fig. 1 and Fig. 2, introduce first execution mode of the utility model fin.This fin 10 is used for the electronic element radiating to the power supply module, and it comprises main part 11 and splicing ear 12.
It is tabular that main part 11 roughly is, and comprises integrated rivet 111 on it.Particularly, this rivet 111 can be through the mode moulding of punching press.Certainly, in the execution mode of other replacement, also can on this main part 11, form rivet 111 through modes well known to those of ordinary skill in the art such as die castings.
Splicing ear 12 comprises the through hole (not indicating) that can cooperate with rivet 111, and this main part 11 is through the through hole riveted of the rivet on it 111 with splicing ear 12.In the concrete course of processing; Earlier the rivet on the main part 11 111 is passed the through hole on the splicing ear 12; Through similar modes such as punching presses the end that rivet 111 passes through hole is flattened again,, prevent that splicing ear 12 from coming off to play the conflict effect that is similar to head of screw.
In this execution mode, splicing ear 12 comprises plate-like portion 121 and from plate-like portion 121 extended terminal supportors 122.Wherein through hole is arranged on the relatively large plate-like portion of area 121, guarantees the reliable of connection.Terminal supportor 122 is in the same plane through the mode and the main part 11 of bending, thereby, corresponding; The breach 112 that cooperates with the bending part (not indicating) of terminal supportor 122 is arranged on the main part 11; Through the breach design here, can also play the effect of escaping to expect, reduce cost.
Also comprise the installing hole 13 that can cooperate on the main part 11 with electronic component in the power supply module.In concrete power supply module, electronic component that can caloric value is bigger is through installing hole 13 and main part 11 fixed installations, and realization electrically connects.Then, terminal supportor 122 is plugged on the corresponding position that PCB goes up this electronic component in the power supply module, realizes the electric connection of this electronic component and power supply module.
As preferred embodiment, the fin 10 of this execution mode also comprises first kink 141 that autonomous body 11 extends, and preferably this first kink 141 and angle between the main part 11 are 90 to spend, to agree with the shape of pcb board in the power supply module.This first kink 141 is used for further strengthening the area of dissipation of fin 10, plays better radiating effect.Should be understood that in other execution mode, this kink 141 can also comprise one or more more a plurality of second kinks 142 that further bending is extended, with the shape of coupling different electrical power module.
And in this execution mode, the fit shapes of main part in the fin 10 11 and kink is that the shape according to pcb board in power supply module and the power supply module designs, and to realize the better fit of fin 10 and power supply module, improves radiating efficiency.
Join Fig. 3 and Fig. 4, introduce second execution mode of the utility model fin, different with first execution mode is; In this execution mode; The main part of fin 20 comprises two parts parallel to each other 211,212, corresponding, it is provided with two splicing ears 221,222.This kind execution mode can satisfy the connection requirement of different electric sub-element and battery modules.
What can expect easily is; For satisfying being connected of more different electric sub-elements and battery modules, this fin can be provided with more a plurality of splicing ears under the prerequisite of not unconventional the utility model skill and spirit; Satisfying more kinds of electronic components, even the connection requirement of a plurality of electronic components.
In two kinds of above-mentioned execution modes, the material of the main part of fin is an aluminium, can play better radiating effect; The material of splicing ear is a tin-coated steel, when guaranteeing good electrical conductivity, guarantees the engineering strength of splicing ear.
The power supply module of taking above-mentioned fin that the utility model provides can have preferable radiating effect, and cost is lower, and product is more competitive.
The utility model has following beneficial effect through above-mentioned execution mode name:
Through the electronic component that heating in the power supply module is higher indirect and power supply module electric connection through the mode of fin, too much heat is in time distributed, guarantee reliability of products.
Through being provided with and the integrated rivet of main part, to realize and the riveted of splicing ear, reduced cost, improved product competitiveness.
The global shape of fin can cooperate with the power supply module according to the pcb board shaped design in power supply module and the power supply module preferably, improves radiating efficiency.
Be to be understood that; Though this specification is described according to execution mode; But be not that each execution mode only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, and those skilled in the art should make specification as a whole; Technical scheme in each execution mode also can form other execution modes that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to the feasibility execution mode of the utility model; They are not the protection range in order to restriction the utility model, allly do not break away from equivalent execution mode or the change that the utility model skill spirit done and all should be included within the protection range of the utility model.
