Description

Guide duct

Technical field

The utility model relates to a kind of guide duct, refers to a kind of guide duct that is used for a radiating module of an electronic product especially.

Background technology

Electronic product is when running, and its electronic component can produce high heat.This high heat must be carried out scatters and disappears reducing this temperature of electronic component, thereby the running of guaranteeing this electronic component is normal.For example, the central processing unit of computer is handled its data at a terrific speed and is produced high heat, and should high heat must promptly be scattered and disappeared, and just can not cause this computer down.Therefore, electronic product must have a radiating module in addition, with the work that its electronic component is dispelled the heat.

Existing radiating module comprises a heat abstractor (as a radiating fin group) and a fan.This fan is installed on this heat abstractor.This radiating module is located in the casing of an electronic product, and this heat abstractor is installed on the electronic component (as a central processing unit) of this electronic product.The high heat that this electronic component produces is passed to this heat abstractor, and the distinguished and admirable band that produces of this fan is from this high warm and flow out outside this casing, with the work that this electronic component is dispelled the heat.

Because have one between this fan and this casing at interval, this distinguished and admirable meeting is stranded in this casing at interval via this, and can't flow out fully outside this casing, cause the radiating effect of this radiating module to reduce.Therefore, a guide duct is set between this fan and this casing, to guide outside this this casing of distinguished and admirable outflow up hill and dale.

Existing guide duct is provided with a plurality of screws and a plurality of trip.These trips are distinguished hook joints in a plurality of hole clippings of the casing of an electronic product, and a plurality of screw is arranged in a plurality of perforation of this casing respectively and distinguishes interlocking in a plurality of screws of this guide duct.Thus, make this guide duct be fixed in this casing and be set at this casing and be located between the fan in this casing.

When above-mentioned existing guide duct is installed in this casing, or be disassembled when this casing, must prepare to be matched with the proper implements of these screws.After these screws are disassembled, be very easy to lose again.As a result, it is time-consuming completely and take a lot of work to mount and dismount the work of this guide duct.In addition, these trips and these screws expose to this casing, have also destroyed the globality of the outward appearance of this casing.

As from the foregoing, above-mentioned existing guide duct on reality is used, obviously has inconvenience and exists with defective, and remain to be improved.

Summary of the invention

Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, and a kind of guide duct is provided, and makes this guide duct just can be mounted to and be disassembled from a fan by tool using, and can keep the globality of the outward appearance of a casing.

For reaching above-mentioned purpose, the utility model provides a kind of guide duct, is immobilizated on the fan, and this fan has a housing, and an outer ring surface of this housing forms several depressed parts, and this guide duct comprises that one is responsible for a wall and a binding wall; This person in charge's wall has the fan end opening in abutting connection with this fan; This binding wall axially extends from this fan end opening of this person in charge's wall, and this binding wall is provided with at least two trips and radially extends to this fan end opening; Wherein a periphery of the outer ring surface of the housing of this fan is matched with this binding wall inboard, and each trip is sticked in corresponding one of them depressed part.

Make guide duct of the present utility model to be hung on simply on this fan by this binding wall and these trips, thereby make this guide duct just can be mounted to and be disassembled from this fan by tool using; In addition, guide duct of the present utility model is fixed in this fan, but not is fixed in the casing of an electronic product, therefore can keep the globality of the outward appearance of this casing.
