Fan module

Abstract

A fan module includes a blade, a motor, a circuit board and a housing having an accommodating space for receiving the blade and the motor. The circuit board has a set of electrical terminals exposed outside the housing. The set of exposed electrical terminals is used for electrically connecting to an electric connecting portion of a carrier without using a cable to receive a power source and/or control signals.

1 . A fan module comprising:
 a blade;   a motor, used to rotate the blade;   a circuit board connected to the motor for controlling the motor, the circuit board having a set of electrical terminals; and   a housing having an accommodating space for receiving the blade and the motor,   wherein the set of electrical terminals is exposed from the housing, and the set of exposed electrical terminals is used to complete an electrical connection between the fan module and a carrier in a cable-less manner by being in direct contact with an electrical connecting portion of the carrier.   
     
     
         2 . The fan module according to  claim 1 , wherein the housing comprises a fan frame, and the circuit board is coupled to the fan frame and acts as a cover of the housing. 
     
     
         3 . The fan module according to  claim 2 , wherein the circuit board has a hollow zone, a plate disposed in the hollow zone, and a plurality of arms connected to the plate and span across the hollow zone. 
     
     
         4 . The fan module according to  claim 3 , wherein the set of electrical terminals is located on the plate. 
     
     
         5 . The fan module according to  claim 2 , wherein the circuit board includes a protrusion at its periphery, the protrusion protruding beyond the periphery of the fan frame, and the set of electrical terminals is located on the protrusion. 
     
     
         6 . The fan module according to  claim 1 , wherein the housing comprises a cover and a fan frame, and the cover and the fan frame are coupled together at their peripheries and collectively form an outlet. 
     
     
         7 . The fan module according to  claim 6 , wherein the cover has a hollow zone, a plate disposed in the hollow zone, and a plurality of arms connected to the plate and span across the hollow zone. 
     
     
         8 . The fan module according to  claim 7 , wherein the circuit board is coupled to the plate such that the circuit board is a part of the cover and the set of electrical terminals is exposed. 
     
     
         9 . The fan module according to  claim 7 , wherein the circuit board and the cover are overlapped, and the cover has an opening via for exposing the set of electrical terminals. 
     
     
         10 . The fan module according to  claim 1 , wherein the electrical connecting portion comprises a conductive resilient tab. 
     
     
         11 . The fan module according to  claim 1 , wherein the electrical connecting portion comprises a slot and a conductive resilient tab disposed in the slot. 
     
     
         12 . The fan module according to  claim 1 , wherein the carrier is a motherboard in a computer.
