Description

Blower module

Technical field

The invention relates to a kind of blower module, refer to especially a kind of simple in structure, can reduce mould and cost of material, simplification number of assembling steps, connectivity is strong, stationarity is good, and can reach the blower module of live inserting and pulling purpose.

Background technique

Usually be provided with the blower module of heat transmission in the general electronics (for example being servomechanism); Dispel the heat that its internal circuit element (for example being the central processing unit (CPU) chip) is produced when the actual operation with wind-force, reason is overheated and suffer damage to protect the electronics internal circuit element therefrom.

Tw Taiwan patent announcement number 487293 " fast insert-pull radiating modules " for example; Its radiation fan is sticked in the L type fixed base; Fixed base one side is provided with a terminal and places casket; After terminal was inserted said terminal placement casket, the contact on the terminal can be reached electric connection with the fan contact, and terminal is pulled out the lead connected system again.Its purpose is hot-swappable and simple and easy replacing fan; But its fan is established as in fixed base, and connector is arranged at outside the fixed base, so fan must separate with connector and assembles; Cause assembling time-consuming; And the strength of connection of its fixed base and fan is low, and fan gets loose with fixed base because of vibrations easily, causes electrically connecting interrupting.

Tw Taiwan patent publication No. 200821804 " radiating module " for example, its fan both sides respectively are provided with an elongated sheet second joint, are provided with trip between said second joint and the fan and engage each other; Outer lower end at said second joint is provided with fixed block in order to connector is fixed in the said second joint outer lower end, and in addition, its housing madial wall in order to ccontaining fan is provided with first joint; Said first joint can engage with said second joint each other, and so that fan is positioned in the said blower-casting, and the fan connector can interconnect with the housing connector; When the user pushes the 4th clamping part at the said second joint top; Second joint and said the first pontes are left,, a kind of hot-swappable and easy radiating module of assembly and disassembly is provided thus even also fan separates with housing; But its fan is arranged in said second joint; And connector is arranged at outside said second joint, so fan must separate with connector and assemble, and causes assembling time-consuming; And owing to only fasten between said second joint and the fan through circular salient point and recess; Its strength of connection is low, and fan gets loose with fixed base because of vibrations easily, causes electrically connecting interrupting.

Tw Taiwan patent announcement M276263 " radiating module " for example, its blower module is outside fan, to be provided with a protecting cover, at said protecting cover top card unification handle, the connector of fan can stretch out said protecting cover, to electrically connect with power connector again; Its purpose is hot-swappable and simple and easy replacing fan, though said case can realize assembling simultaneously the purpose of fan and connector, and the position that its protecting cover provides connector to stretch out; Must be corresponding to the position of said connector; That is said protecting cover can't be applicable to other kind fans that connector position is different only for the fan that is assembled in specific kenel surely; In addition; The user grips said handle blower module being inserted or taken out fan frame, and the bond sites intensity of said handle and protecting cover must be able to be born the weight of protecting cover and fan, otherwise causes handle to get loose easily or rupture.
