Television, radiating member, and electronic apparatus

Abstract

According to one embodiment, an electronic apparatus includes a housing, a heat-generating component in the housing, a first radiating portion in the housing thermally connected to the heat-generating component, a second radiating portion in the housing thermally connected to the heat-generating component, and a fan configured to blow air to the first radiating portion and the second radiating portion.

1 . A television comprising:
 a housing comprising an outlet;   a heat-generating component in the housing;   a fan configured to discharge air to the heat-generating component;   a first heat sink having a surface facing the outlet;   a heat transfer member configured to thermally connect the heat-generating component to the first heat sink; and   a second heat sink between the heat-generating component and the first heat sink in a flow path of the air from the fan and thermally connected to the heat-generating component.   
     
     
         2 . The television of  claim 1 ,
 wherein the second heat sink has a plate shape.   
     
     
         3 . The television of  claim 1 , further comprising:
 a metal plate comprising the second heat skink and a heat-receiving portion facing the heat-generating component.   
     
     
         4 . The television of  claim 1 ,
 wherein the second heat sink comprises a plurality of projections.   
     
     
         5 . The television of  claim 4 ,
 wherein at least some of the projections comprise a hole through which the air can flow.   
     
     
         6 . The television of  claim 5 , further comprising:
 a circuit board comprising the heat-generating component,   wherein at least a portion of the second heat sink is disposed over the circuit board.   
     
     
         7 . The television of  claim 6 ,
 wherein the second heat sink comprises a first surface facing the circuit board and a second surface opposite the first surface, and   the holes pass through the second heat sink from the first surface to the second surface.   
     
     
         8 . The television of  claim 7 , comprising a gap between the second heat sink and the circuit board, through which the air can flow,
 wherein the second heat sink is further away from the circuit board than the heat receiving portion.   
     
     
         9 . The television of  claim 7 , further comprising:
 a pressing member comprising a first portion facing the heat pipe and a second portion fixed to the circuit board,   wherein the second heat sink comprises a cut-out portion passing through the second heat sink from the first surface to the second surface,   and wherein the second portion of the pressing member is disposed in the cut-out portion.   
     
     
         10 . A radiating member comprising:
 a metal plate comprising
 a heat-receiving portion configured to face a heat-generating component of a circuit board; and 
 a radiating portion comprising a projection. 
   
     
     
         11 . The radiating member of  claim 10 , wherein the projection comprises a hole through which air can flow. 
     
     
         12 . An electronic apparatus comprising:
 a housing;   a heat-generating component in the housing;   a first radiating portion in the housing thermally connected to the heat-generating component;   a second radiating portion in the housing thermally connected to the heat-generating component; and   a fan configured to blow air to the first radiating portion and the second radiating portion.   
     
     
         13 . The electronic apparatus of  claim 12 ,
 wherein the heat-generating component is between the second radiating portion and the fan in a flow path of the air, and   the fan is configured to discharge the air to the heat-generating component.
