Mobile communication terminal having radiant-heat sheet
A mobile communication terminal with a radiant-heat function is provided. The mobile communication terminal includes: a display module; a rear cover; an inner support structure positioned between the display module and the rear cover and including a first surface facing the display module and a second surface facing an opposite side to the display module; a first radiant-heat sheet positioned between the first surface of the support structure and the display module; a printed circuit board positioned between the first radiant-heat sheet and the first surface of the support structure; and a second radiant-heat sheet positioned between the second surface of the support structure and the rear cover.
1. A mobile communication terminal comprising:
a display module;
a rear cover;
an inner support structure positioned between the display module and the rear cover and including a first surface facing the display module and a second surface facing away from the display module, wherein the support structure includes a space for accommodating a battery and wherein an antenna pattern is disposed on the battery;
a first radiant-heat sheet positioned between the first surface of the support structure and the display module;
a printed circuit board positioned between the first radiant-heat sheet and the first surface of the support structure, wherein the printed circuit board includes a heat generation body spaced apart from the battery; and
a second radiant-heat sheet positioned between the second surface of the support structure and the rear cover, the second radiant-heat sheet connecting the heat generation body to the battery and configured to transfer heat from the heat generation body to the battery; and
wherein the second radiant-heat sheet does not contact the antenna pattern.
2. The mobile communication terminal of claim 1 , and
the second radiant-heat sheet includes a portion formed at a position corresponding to the heat generation body.
3. The mobile communication terminal of claim 2 , wherein the support structure includes another pattern which is metal.
4. The mobile communication terminal of claim 3 , wherein the another pattern included inside the support structure includes a NFC antenna pattern.
5. The mobile communication terminal of claim 1 , wherein at least one of the first radiant-heat sheet and the second radiant-heat sheet includes at least one of natural graphite particles, compressed particles of exfoliated graphite, artificial graphite particles, copper, graphene particles, CNT, and a graphene hybrid.
6. The mobile electronic device of claim 1 , wherein the antenna pattern is a wireless charging antenna.
7. A mobile electronic device comprising:
a display module;
an inner support structure;
wherein the support structure includes a space for accommodating a battery and wherein an antenna pattern is disposed on the battery;
an inner bracket positioned between the display module and the inner support structure and including a first surface facing the display module and a second surface facing away from the display module;
a first radiant-heat sheet positioned between the first surface of the inner bracket and the display module;
a printed circuit board positioned between the second surface of the inner bracket and the support structure, wherein the printed circuit board includes a heat generation body spaced apart from the battery; and
a second radiant-heat sheet positioned between the printed circuit board and the inner support structure, the second radiant-heat sheet connecting the heat generation body to the battery and configured to transfer heat from the heat generation body to the battery; and
wherein the second radiant-heat sheet does not contact the antenna pattern.
8. The mobile electronic device of claim 7 , wherein at least one of the first radiant-heat sheet and the second radiant-heat sheet includes at least one of natural graphite particles, compressed particles of exfoliated graphite, artificial graphite particles, copper, graphene particles, CNT, and a graphene hybrid.
