Abstract

A flat display apparatus includes a display unit; a housing configured to accommodate the display unit; a support member configured to support the housing; and a cooling device configured to radiate heat of a heating element which is mounted in the housing, wherein the cooling device includes a first far infrared ray transfer member which is thermally connected to the heating element in the housing and a second far infrared ray transfer member which is thermally connected to an external portion of the housing at a rear surface side, wherein a radiating surface of the first far infrared ray transfer member and an absorbing surface of the second far infrared ray transfer member are disposed to oppose each other with the housing interposed therebetween, and wherein heat radiated from the first far infrared ray transfer member is radiated at both plane surface of the second far infrared ray transfer member.

Claims (16)

1. A flat display apparatus comprising:

a display unit;

a housing configured to accommodate the display unit;

a support member configured to support the housing; and

a cooling device configured to radiate heat of a heating element which is mounted in the housing;

the cooling device includes a first far infrared ray transfer member which is thermally connected to the heating element in the housing and a second far infrared ray transfer member which is thermally connected to the outside at a rear surface side of the housing and has two plane surfaces,

a radiating surface of the first far infrared ray transfer member and an absorbing surface of the second far infrared ray transfer member are disposed to oppose to each other with the housing interposed therebetween, and

heat radiated from the first far infrared ray transfer member is in turn radiated at both of the plane surfaces of the second far infrared ray transfer member.

2. The flat display apparatus according to claim 1 , wherein

the support member includes a first support member which is integrally fixed to the housing and a second support member which slidably reciprocates with respect to the first support member,

the second support member is thermally connected to or disconnected from the second far infrared ray transfer member according to the reciprocating movement with respect to the first support member, and

the second support member moves to the first support member to be thermally connected with the second far infrared ray transfer member in the case of the flat display apparatus being installed in close to a wall.

3. The flat display apparatus according to claim 2 ,

wherein the second support member includes a bias member which holds the second support member so as to apply an elastic biasing force in a direction away from the first support member and an elastic pressing member which presses the second far infrared ray transfer member by a pressing force from the outside.

4. The flat display apparatus according to claim 2 ,

wherein the second support member includes a bias member which holds the second support member so as to apply an elastic biasing force in a direction away from the first support member and an elastic pressing member which presses the second far infrared ray transfer member by a pressing force from the outside.
