Tesla valve fan module and its cooling system

Abstract

This invention, a Tesla valve fan module, includes a housing and an impeller. The housing encloses a main flow channel and has an air inlet, an air outlet, and a drainage outlet connecting to the main flow channel. A Tesla valve structure extends outward from the drainage outlet and is connected to the drainage outlet. The impeller is pivotally mounted within the housing to drive airflow into the main flow channel from the air inlet. Part of the airflow exits the main flow channel through the air outlet, while another part exits the main flow channel through the drainage outlet and the Tesla valve structure. By incorporating the Tesla valve structure, a stable unidirectional airflow is provided and backflow is suppressed, which can stably increase the air pressure in a predetermined direction, thereby solving the problems of easy airflow dissipation and insufficient air pressure and velocity in conventional fans.

Claims

1. A Tesla valve fan module, comprising: a housing surrounding a main channel, the housing having an air inlet, an air outlet and a flow outlet communicating with the main channel, and a Tesla valve structure extending outward from the flow outlet and communicating with the flow outlet; and an impeller pivotally mounted within the housing to drive airflow from the air inlet into the main channel, wherein a portion of the airflow is discharged from the main channel through the air outlet, and another portion of the airflow is discharged from the main channel through the flow outlet and the Tesla valve structure.

2. The Tesla valve fan module as claimed in claim 1, wherein the Tesla valve structure and the housing are integrally formed or two independent components are detachably connected as one unit.

3. The Tesla valve fan module as claimed in claim 1, wherein the air intake outlet and the air outlet are respectively located on opposite sides of the housing.

4. The Tesla valve fan module of claim 1, wherein the drain outlet and the Tesla valve structure are arranged along the tangential direction of the main flow channel.

5. The Tesla valve fan module of claim 1, wherein the Tesla valve structure has a straight flow channel and a plurality of branch flow channels, the branch flow channels being disposed on both sides of the straight flow channel, extending out of the straight flow channel in the opposite direction, and reconnecting back to the straight flow channel in the forward direction.

6. The Tesla valve fan module of claim 1, wherein the Tesla valve structure has an inlet and an outlet, the inlet being connected to the outlet and the outlet being oriented in a predetermined direction, thereby providing a unidirectional stable airflow in the predetermined direction.

7. A heat dissipation system suitable for a heat source, comprising: a heat dissipation fin assembly; a heat pipe with its two ends respectively contacting the heat source and the heat dissipation fin assembly; and a Tesla valve fan module, comprising a housing and an impeller; the housing encloses a main flow channel, the housing having an air inlet, an air outlet, and a drainage outlet communicating with the main flow channel, the air outlet facing the heat dissipation fin assembly, and a Tesla valve structure extending outward from the drainage outlet, the Tesla valve structure communicating with the drainage outlet; the impeller is pivotally mounted within the housing to drive airflow from the air inlet into the main flow channel, wherein a portion of the airflow is discharged through the air outlet and passes through the heat dissipation fin assembly, and another portion of the airflow is discharged through the drainage outlet and passes through the Tesla valve structure toward the heat source, thereby providing a unidirectional stable airflow to the heat source.

8. The cooling system of claim 7, wherein the Tesla valve structure is integrally formed with the housing or two separate components are detachably connected as one unit.

9. The cooling system of claim 7, wherein the Tesla valve structure has an inlet and an outlet, the inlet being connected to the drain outlet and the outlet being directed toward the heat source.

10. The cooling system of claim 7, wherein the Tesla valve structure has a straight flow channel and a plurality of branch flow channels, the branch flow channels being disposed on both sides of the straight flow channel, extending out of the straight flow channel in the opposite direction, and reconnecting back to the straight flow channel in the forward direction.
