Heat dissipation module

Abstract

A heat dissipation module includes a centrifugal fan and a heat pipe. The centrifugal fan includes at least one axial air inlet and a radial air outlet, wherein an air channel sidewall of the centrifugal fan has heat dissipation fins in an inner wall thereof. The heat pipe has a heat source contact section and a heat dissipation section, the heat dissipation section is in contact with an outer wall of the air channel sidewall, and the heat source contact section is in contact with a heat source.

What is claimed is: 
     
         1 . A heat dissipation module comprising:
 a centrifugal fan comprising at least one axial air inlet and a radial air outlet, wherein an air channel sidewall of the centrifugal fan has heat dissipation fins in an inner wall thereof; and   a heat pipe comprising a heat source contact section and a heat dissipation section, wherein the heat dissipation section is in contact with an outer wall of the air channel sidewall, and the heat source contact section is in contact with a heat source.   
     
     
         2 . The heat dissipation module of  claim 1 , wherein the heat dissipation section has a circular cross-section. 
     
     
         3 . The heat dissipation module of  claim 2 , wherein the air channel sidewall has a concave arc section in an outer wall thereof to be in contact with the heat dissipation section of the heat pipe. 
     
     
         4 . The heat dissipation module of  claim 1 , wherein the air channel sidewall is a metallic sidewall. 
     
     
         5 . The heat dissipation module of  claim 4 , wherein the centrifugal fan further comprises an upper cover and a lower cover, the upper cover, the lower cover and the air channel sidewall collectively form a complete housing of the centrifugal fan. 
     
     
         6 . The heat dissipation module of  claim 5 , wherein the upper cover is a metal cover or a plastic cover. 
     
     
         7 . The heat dissipation module of  claim 5 , wherein the lower cover is a metal cover or a plastic cover. 
     
     
         8 . The heat dissipation module of  claim 1 , wherein a contact section between the heat dissipation section and the outer wall of the air channel sidewall is greater than a half length of the air channel sidewall. 
     
     
         9 . The heat dissipation module of  claim 1 , wherein the heat dissipation fins have cutouts to collectively define an inner air channel of the centrifugal fan. 
     
     
         10 . The heat dissipation module of  claim 9 , wherein the cutouts of the heat dissipation fins are V-shaped cutouts.
