Abstract
A holding device for holding a cooling fan comprising: a duct having a hollow in which a cooling fan is to be fitted; a stopper portion which keeps one operative end of the cooling fan from further moving to hold the cooling fan at a fitting position; and a plurality of elastic wall segments formed in a cooling fan insertion end of a wall of the duct; wherein each of some of the plurality of elastic wall segments is formed with a locking claw for keeping the other operative end of the cooling fan from moving. With this construction, the cooling fan 31 can be more surely mounted in a duct. Consequently, vibration reduction effect and sound reduction effect with respect to the cooling fan is improved.
Claims15
A cooling apparatus comprising:
- (a) a cooling fan;
- and
- (b) a holding device for holding said cooling fan;
- said holding device including:
- a duct having side surfaces forming a hollow in which said cooling fan is fitted;
- a stopper which keeps one operative end of said cooling fan from further moving to hold said cooling fan at a fitting position;
- a first elastic wall segment formed on one of said side surfaces of said duct, said first elastic wall segment is formed with a locking claw which engages with a predetermined portion of said cooling fan to lock said cooling fan at said fitting position;
- and
- a second elastic wall segment formed on another one of said side surfaces of said duct, said second elastic wall segment is formed with a projection that presses said cooling fan inward.
A cooling apparatus comprising:
- a cooling fan having first operative end and a second operative end;
- a holding device for holding said cooling fan;
- said holding device including:
- a duct having side surfaces forming a hollow in which said cooling fan is fitted;
- a stopper which keeps said first operative end of said cooling fan from further moving to hold said cooling fan at a fitting position;
- and
- an elastic wall segment formed on one of said side surfaces of said duct, said elastic wall segment is formed with a projection (33f:
- FIG. 5B), said projection being formed with:
- a first slanting surface 33g which engages with a predetermined position of said second operative end of said cooling fan when said cooling fan is fully inserted into said duct in such a manner that it presses said cooling fan inward and keeps said cooling fan from moving in a removing direction of said cooling fan from said duct.
A holding device for holding a cooling fan comprising:
- a duct having a hollow in which a cooling fan is to be fitted;
- a stopper portion which keeps one operative end of said cooling fan from further moving to hold said cooling fan at a fitting position;
- a first elastic wall segment formed in a cooling fan insertion end of a wall of said duct, said first elastic wall segment is formed with a locking claw for keeping said operative end of said cooling fan from moving;
- and
- a second elastic wall segment formed in said cooling fan insertion end of said wall of said duct, said second elastic wall segment is formed with a projection that presses said cooling fan inward.
