Abstract
An advection fan includes a housing having a metal housing base and a closure member. A lateral wall is arranged between the metal housing base and the closure member and includes an air inlet and an air outlet. A horizontal air passage is defined between the metal housing base and the closure member. The metal housing base includes an engagement section. A stator includes a coil unit embedded in or abutting and attached to the engagement section of the metal housing base. The coil unit abuts the engagement face of the metal housing base. The coil unit includes a substrate and at least one coil formed on a surface of the substrate by printing circuit or electroforming process. An impeller is rotatably coupled to the shaft tube of the stator. A gap is formed between the impeller and the coil unit of the stator.

A advection fan comprising:
- a housing including a metal housing base and a closure member, with a lateral wall arranged between the metal housing base and the closure member and including an air inlet and an air outlet, with a horizontal air passage defined between the metal housing base and the closure member, with the metal housing base including an engagement section including a through-hole;
- a stator including a shaft seat and a coil unit, with the shaft seat integrally wrapping the through-hole of the metal housing base, with the shaft seat including a compartment having a shaft coupling portion, with the coil unit embedded in the compartment, with the coil unit including a substrate and at least one coil formed on a surface of the substrate by printing circuit or electroforming process;
- and
- an impeller rotatably coupled to the shaft coupling portion of the shaft seat of the stator, with a gap formed between the impeller and the coil unit of the stator.
A advection fan comprising:
- a housing including a metal housing base and a closure member, with a lateral wall arranged between the metal housing base and the closure member and including an air inlet and an air outlet, with a horizontal air passage defined between the metal housing base and the closure member, with the metal housing base including an engagement section having a recess, with the recess including a bottom having a fixing hole;
- a stator including a shaft tube and a coil unit, with the shaft tube fixed in the fixing hole of the recess, with the coil unit embedded in the recess, with the coil unit including a substrate and at least one coil formed on a surface of the substrate by printing circuit or electroforming process;
- and
- an impeller rotatably coupled to the shaft tube of the stator, with a gap formed between the impeller and the coil unit of the stator.
