Remote radio unit

Abstract

The present invention relates to a communication device, and in particular, to a Remote Radio Unit (RRU). The RRU includes an RRU radiator structural member and a shell, where the shell includes an evaporator, radiating pipes and a shell body, the inside of the evaporator is in communication with the radiating pipes to form a loop for holding a phase change medium, and the radiating pipes are disposed on the shell body; and the evaporator is connected to a radiator of the RRU radiator structural member. By using the RRU according to the present invention, the radiating efficiency can be improved.

1 . A Remote Radio Unit (RRU) comprising:
 an RRU radiator structural member and a shell, wherein the shell comprises an evaporator, radiating pipes and a shell body, the inside of the evaporator is in communication with the radiating pipes to forma loop for holding a phase change medium, and the radiating pipes are disposed on the shell body; and   the evaporator is connected to a radiator of the RRU radiator structural member.   
     
     
         2 . The RRU according to  claim 1 , wherein a groove exists in the evaporator, and the groove is in communication with the radiating pipes to form a loop. 
     
     
         3 . The RRU according to  claim 1 , wherein a phase changeable medium is filled in the radiating pipes. 
     
     
         4 . The RRU according to  claim 3 , wherein the phase changeable medium is at least a one of water, ammonia or Freon. 
     
     
         5 . The RRU according to  claim 1 , wherein the radiating pipes are at least a one of: embedded in the shell body or disposed on the outside of the shell body. 
     
     
         6 . The RRU according to  claim 1 , wherein the shell body comprises at least a one of plastic material or metal material, and the radiating pipes comprise at least a one of plastic material or metal material. 
     
     
         7 . The RRU according to  claim 6 , wherein the metal material comprises at least one of copper or aluminum. 
     
     
         8 . The RRU according to  claim 6 , wherein the plastic material comprises heat conducting plastic. 
     
     
         9 . The RRU according to  claim 1 , wherein the shell body is opened with a ventilation hole. 
     
     
         10 . The RRU according to  claim 1 , wherein the horizontal position of the evaporator is horizontal to or lower than that of the radiating pipes.
