Abstract
Provided is a cooling fan, which relates to the technical field of a cooling fan, and comprises a bearing seat, a main shaft, a heat dissipation device, an impeller and a housing. The utility model is characterized in that one end of the bearing seat is provided with a housing; the impeller is disposed in the housing; the bearing seat is connected to the impeller through the main shaft; the heat dissipation device sleeves on the main shaft; the dissipation device is evenly divided into two parts which are in a movable bolt joint. The utility model has advantages of simple structure, convenient dismounting and maintenance, and easy installation.
Description
Technical field
The utility model relates to the technical field of the blower fan with heat sinking function.
Background technique
The construction for heat radiating device of blower fan is to adopt ring at present, must earlier sink be inserted in main shaft during installation and refill impeller, and trouble is installed, and inconvenience is regulated.And between sink and the main shaft is to fixedly connected, so dismounting and maintenance inconvenience.
Summary of the invention
The utility model purpose provides a kind of simple in structure, and field-strip is convenient, cooling fan easy for installation.
A kind of cooling fan comprises bearing support, main shaft, sink, impeller, casing, and an end of bearing support is oppositely arranged casing, and impeller is set in the casing, and bearing support is connected with impeller by main shaft; It is characterized in that sink is nested with on main shaft.
Sink of the present utility model evenly is divided into two parts, flexibly connects between two-part.
The utility model is divided into evenly that bolt connects between the sink of two parts.
The utility model adopts technique scheme, compared with prior art has following advantage: sink of the present utility model is installed on the main shaft between impeller and the bearing support.Described sink, separated into two parts couples together by bolt between two-part, makes this sink can be installed on the mounted blower fan very easily and can regulate the mounting point arbitrarily, and is simple in structure, installs, dismounting, maintenance be convenient.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
