Abstract

A display device includes a display module, a support housing, and a heat dissipating module. The display module has a back surface, wherein at least a portion of the back surface has a first heat dissipating block. The support housing is disposed opposite the back surface. The support housing sandwiches with the back surface a mezzanine space for disposing the first dissipating module. The first heat dissipating module includes a first heat dissipating body and a first elastic unit. The first heat dissipating module has a first heat exchange surface and a first pressure receiving surface facing away from each other, wherein the first heat exchange surface is heat exchange connected to the first heat dissipating block. The first elastic unit disposed compressed between the first pressure receiving surface and the support housing, wherein with the support housing as a source of reaction force, the first elastic unit provides the first pressure receiving surface with a first pressing force.

First claim

What is claimed is:

1. A display device, comprising:
a display module having a back surface, wherein the back surface has a first heat dissipating block;
a support housing disposed opposite the back surface and sandwiches a mezzanine space with the back surface;
a first heat dissipating module disposed in the mezzanine space, the first heat dissipating module has:
a first heat dissipating body having a first heat exchange surface and a first pressure receiving surface facing away from each other, wherein the first heat exchange surface is heat exchange connected to the first heat dissipating block;
a first elastic unit disposed compressed between the first pressure receiving surface and the support housing; and

a second heat dissipating module disposed in the mezzanine space, the second heat dissipating module has:
a second heat dissipating body having a second heat exchange surface and a second pressure receiving surface facing away from each other, wherein the back surface includes a second heat dissipating block independent of the first heat dissipating block, and the second heat dissipating block is heat exchange connected with the second heat dissipating block;
a second elastic unit disposed compressed between the second pressure receiving surface and the support housing;

wherein the first elastic unit provides the first pressure receiving surface a first pressing force with the support housing as a source of reaction force, the second elastic unit provides the second pressure receiving surface with a second pressing force with the support housing as a source of reaction force, and the second pressing force is greater than the first pressing force.

2. The display device of claim 1 , wherein the first heat dissipating body has a guide post disposed on the first pressure receiving surface, the first elastic unit includes a coil spring, and the coil spring is fitted on the guide post.

3. The display device of claim 1 , wherein the first heat dissipating body has a plurality of heat dissipating posts disposed on the first pressure receiving surface.

4. The display device of claim 3 , wherein the first elastic unit includes a coil spring, the coil spring is fitted on one of the heat dissipating posts.

5. The display device of claim 1 , further including at least a position limiting unit disposed on a side of the first heat dissipating body and connected to at least one of the back surface and the support housing to limit the displacement of the first heat dissipating body on a plane dimension parallel to the back surface.

6. The display device of claim 5 , wherein the position limiting unit is formed as a strip shape and extends parallel to the side of the first heat dissipating body.

7. The display device of claim 1 , wherein the support housing includes at least one support board opposite to the first pressure receiving surface, and an end of the first elastic unit touches against the support board.

8. The display device of claim 1 , wherein the first heat dissipating module includes at least one heat conducting medium layer disposed between the first heat exchange surface and the first head dissipating block, the heat conducting medium layer materially has respectively more elasticity relative to the first heat exchange surface and the heat dissipating block.

9. A display device, comprising:
a display module having a back surface, wherein the back surface has a first heat dissipating block;
a support housing disposed opposite the back surface and sandwiches a mezzanine space with the back surface;
a first heat dissipating module disposed in the mezzanine space, the first heat dissipating module has:
a first heat dissipating body having a first heat exchange surface and a first pressure receiving surface facing away from each other, wherein the first heat exchange surface is heat exchange connected to the first heat dissipating block;
a guide post disposed on the first pressure receiving surface:

a first elastic unit disposed compressed between the first pressure receiving surface and the support housing, wherein the first elastic unit includes a coil spring, and the coil spring is fitted on the guide post.

10. The display device of claim 9 , further including at least a position limiting unit disposed on a side of the first heat dissipating body and connected to at least one of the back surface and the support housing to limit the displacement of the first heat dissipating body on a plane dimension parallel to the back surface.

11. The display device of claim 10 , wherein the position limiting unit is formed as a strip shape and extends parallel to the side of the first heat dissipating body.
