Radiator

Abstract

A radiator includes a fan, a heat pipe, and a heat-dissipation fin arranged on the heat pipe. The heat pipe is perpendicularly inserted in a first hole of the heat-dissipation fin. The heat-dissipation fin is provided with a second hole for heat dissipation. A flow-guide assembly, including a first sheet, a second sheet and a third sheet, is arranged at the second hole. The first and second sheets are provided at two opposite ends of the second hole, respectively, and extend out of the heat-dissipation fin. The third sheet is inclinedly connected between the first and second sheets, and has a side abutting a side of the second hole. During operation, air is blown by the fan to the heat-dissipation fin, and the air flow partially flows out through the second hole to form a return flow, prolonging the time for airflow to pass through the heat-dissipation fin.

What is claimed is: 
     
         1 . A radiator, comprising:
 a fan;   a heat pipe; and   a heat-dissipation fin arranged on the heat pipe;   wherein the heat pipe is perpendicularly inserted into a first hole of the heat-dissipation fin; the heat-dissipation fin is further provided with a second hole for heat dissipation; a flow guide assembly is provided at the second hole; the flow guide assembly comprises a first sheet, a second sheet and a third sheet; the first sheet and the second sheet are provided at two opposite ends of the second hole, respectively; the first sheet and the second sheet are configured to extend out of a top surface of the heat-dissipation fin; the third sheet is inclinedly connected between the first sheet and the second sheet; and a side of the third sheet abuts a side of the second hole.   
     
     
         2 . The radiator of  claim 1 , wherein the number of the second hole is 24, and 24 second holes are symmetrically distributed in an array at four corners of the heat-dissipation fin. 
     
     
         3 . The radiator of  claim 1 , wherein the number of the second hole is 24, and 24 second holes are symmetrically distributed at four corners of the heat-dissipation fin in a staggered manner. 
     
     
         4 . The radiator of  claim 1 , wherein an included angle between the third sheet and the top surface of the heat-dissipation fin is 20-30 degrees. 
     
     
         5 . The radiator of  claim 1 , wherein an opening of the flow guide assembly faces towards outside of the heat-dissipation fin. 
     
     
         6 . The radiator of  claim 1 , wherein the number of the heat-dissipation fin is at least two; at least two heat-dissipation fins are stacked on the heat pipe; and a spacing between adjacent two heat-dissipation fins is larger than a height of a highest point of the flow guide assembly. 
     
     
         7 . The radiator of  claim 1 , wherein a fixing base is arranged at a bottom of the heat pipe; the fixing base is made of aluminum, and has a T-shaped structure; and each side of the fixing base is provided with a screw hole. 
     
     
         8 . The radiator of  claim 7 , wherein a bottom surface of the fixing base is provided with at least one first groove; the number of the at least one first groove is more than or equal to the number of the heat pipe; the at least one first groove fits the heat pipe; and a top surface of the fixing base is provided with at least one second groove. 
     
     
         9 . The radiator of  claim 1 , wherein a heat conduction base is arranged on a bottom of the heat pipe, and the heat conduction base is provided with at least one groove; the at least one groove fits the heat pipe; and the number of the groove is more than or equal to the number of the heat pipe. 
     
     
         10 . The radiator of  claim 9 , wherein the heat conduction base is made of copper.
