Claims
- 1. An electronic component cooling apparatus comprising:
- a motor including a rotor and a stator;
- an impeller securely mounted on said rotor and including a plurality of blades for sucking air from one side in an axial direction of a revolving shaft of said motor;
- a casing formed therein with a cavity in which said impeller is received;
- said casing including a wall arranged so as to surround said impeller to define said cavity, and at least one discharge port through which air sucked into said cavity is discharged;
- said motor including a housing member supported on an end of said wall defined on said one side through a plurality of webs arranged thereon so as to be spaced from each other at intervals in a circumferential direction thereof;
- said webs having legs arranged so as to extend on said one side to provide a spacer means for establishing a space which permits air to be suckedly introduced into said cavity in a radial direction of said revolving shaft.
- 2. An electronic component cooling apparatus comprising:
- motor including a rotor and a stator;
- an impeller securely mounted on said rotor and including a plurality of blades for sucking air from one side in an axial direction of a revolving shaft of said motor;
- a casing formed therein with a cavity in which said impeller is received, said casing including a wall arranged so as to surround said impeller to define said cavity, and at least one discharge port through which air sucked into said cavity is discharged;
- said casing being provided with a spacer means, said spacer means being arranged so as to outwardly project on said one side to provide a space through which air is suckedly introduced into said cavity in a radial direction of said revolving shaft;
- said spacer means being constructed of legs of webs for supporting a housing member of said motor on said casing.
- 3. An electronic component cooling apparatus as defined in claim 2, wherein said spacer means is formed into a length in said axial direction which permits a suction pressure enough to permit a predetermined amount of air to be suckedly introduced into said cavity when an opposite member is arranged on said spacer means in a manner substantially opposite to said cavity.
- 4. An electronic component cooling apparatus as defined in claim 2, wherein said casing is provided with one said discharge port for discharging air in only one direction.
- 5. An electronic component cooling apparatus as defined in claim 2, wherein said casing is provided with a plurality of said discharge ports for discharging air in the axial direction of said revolving shaft.
