Abstract

The cooling apparatus includes a heat receiving portion to receive heat from the heating element, a radiator, a first heat pipe having one end portion to receive heat from the heat receiving portion and anther end portion inserted in the radiator, and a second heat pipe to receive the heat from the heat receiving portion via the first heat pipe, the second heat pipe including one end portion arranged on the first pipe and another end portion arranged around the radiator, wherein the second heat pipe overlaps with a region of the first heat pipe extending from the heat receiving portion to the radiator in a plan view of the cooling apparatus.

Claims

exact text as granted — not AI-modified
1 . A cooling apparatus for cooling a heating element accommodated in an electronic apparatus, the cooling apparatus comprising:
 a heat receiving portion to receive heat from the heating element;   a radiator;   a first heat pipe having one end portion to receive heat from the heat receiving portion and anther end portion inserted in the radiator; and   at least one second heat pipe to receive the heat from the heat receiving portion via the first heat pipe, the second heat pipe including one end portion arranged on the first pipe and another end portion arranged around the radiator, wherein the second heat pipe overlaps with a region of the first heat pipe extending from the heat receiving portion to the radiator in a plan view of the cooling apparatus.   
     
     
         2 . The cooling apparatus according to  claim 1 , further comprising a second heat receiving portion different from the heat receiving portion, wherein heat from the second heat receiving portion is received at the one end portion of the first heat pipe. 
     
     
         3 . The cooling apparatus according to  claim 1 , further comprising a second heat receiving portion different from the heat receiving portion,
 wherein heat from the second heat receiving portion is received at the one end portion of the first heat pipe, and   wherein the second heat pipe overlaps with a region of the first heat pipe extending from the second heat receiving portion to the radiator in a plan view of the cooling apparatus.   
     
     
         4 . The cooling apparatus according to  claim 1 , further comprising a second heat receiving portion different from the heat receiving portion,
 wherein the second heat pipe includes one end of a radiator side and another end of a heat receiving portion side, and   wherein the anther end receives heat from the second heat receiving portion via the first heat pipe.   
     
     
         5 . The cooling apparatus according to  claim 4 , further comprising a third heat receiving portion arranged between the heat receiving portion and the radiator,
 wherein the first heat pipe receives heat from the third heat receiving portion, and   wherein the second heat pipe receives the heat from the third heat receiving portion via the first heat pipe.   
     
     
         6 . The cooling apparatus according to  claim 1 , wherein two or more second heat pipes overlapping each other are arranged on the first heat pipe. 
     
     
         7 . The cooling apparatus according to  claim 1 , further comprising:
 a second radiator different from the radiator; and   a third heat pipe to receive the heat from the heat receiving portion via the first heat pipe and the second heat pipe, wherein the third heat pipe includes one end portion overlapping the second heat pipe and another end portion inserted in the second radiator.   
     
     
         8 . The cooling apparatus according to  claim 1 , wherein the first heat pipe is formed in a flat strip shape. 
     
     
         9 . The cooling apparatus according to  claim 1 , wherein the second heat pipe is formed in a flat strip shape. 
     
     
         10 . An electronic apparatus, comprising:
 a housing;   a heating element accommodating the housing; and   a cooling apparatus to cool the heating element, the cooling apparatus including:
 a heat receiving portion to receive heat from the heating element; 
 a radiator; 
 a first heat pipe having one end portion to receive heat from the heat receiving portion and anther end portion inserted in the radiator; 
 at least one second heat pipe to receive the heat from the heat receiving portion via the first heat pipe, the second heat pipe including one end portion arranged on the first pipe and another end portion arranged around the radiator, wherein the second heat pipe overlaps with a region of the first heat pipe extending from the heat receiving portion to the radiator in a plan view of the cooling apparatus; and 
 a fan to generate airflow which flows inside and around the radiator, and flows out from an air exhaust formed in the housing.
