Abstract

A protective device capable of dissipating heat for protecting an electronic device includes a carrier and a flexible heat transfer unit. The carrier is used for correspondingly connecting to or receiving the electronic device therein and has a plurality of edges. The flexible heat transfer unit is arranged at one of the edges of the carrier and has a first and a second extended portion. The first extended portion is extended onto and connected to an inner side of the carrier, whereas the second extended portion is extended away from the carrier to connect to a flip cover. The first extended portion of the flexible heat transfer unit is in direct or indirect contact with a heat source of the electronic device, such that heat produced by the heat source can be transferred from the carrier to the flip cover via the flexible heat transfer unit.

First claim

What is claimed is:

1. A protective device capable of dissipating heat for protecting an electronic device, comprising:
a carrier for correspondingly connecting to or receiving the electronic device therein and having a first inner side oriented to the electronic device and a plurality of edges surrounding the first inner side;
a flexible connecting element being arranged at one of the edges of the carrier and having two opposite ends that respectively form a first and a second extended portion; the first extended portion being extended onto and partially across an upper surface of the first inner side of the carrier, the first extended portion being connected to the first inner side of the carrier, and the second extended portion being extended away from the carrier to form a flip cover, which can be turned towards or away from the carrier; and the first extended portion being in direct or indirect contact with at least one heat source of the electronic device,
wherein the first extended portion has a first contact surface facing away from the first inner side of the carrier and oriented to the electronic device and the flexible connecting element is a flexible thin heat PIPE.

2. The protective device claimed in claim 1 , wherein the first contact surface of the first extended portion is in contact with the heat source of the electronic device.

3. The protective device as claimed in claim 1 , wherein the carrier is provided with an on-carrier heat transfer element, which is in contact with the at least one heat source of the electronic device and has a first contact end and a second contact end; and one of the first and the second contact end being in contact with the first contact surface of the first extended portion.

4. The protective device as claimed in claim 1 , wherein the flexible connecting element is selected from the group consisting of a graphite sheet and a metal foil-attached graphite sheet.

5. The protective device as claimed in claim 4 , wherein the metal foil-attached graphite sheet includes at least one layer of metal foil attached to at least one layer of graphite sheet.

6. The protective device as claimed in claim 5 , wherein the metal foil is made of a material selected from the group consisting of gold, silver, copper, aluminum, and any combination thereof.

7. The protective device as claimed in claim 6 , wherein the first contact surface is the metal foil.

8. The protective device as claimed in claim 1 , wherein the flip cover is selected from the group consisting of a graphite sheet and a metal foil-attached graphite sheet.

9. The protective device as claimed in claim 1 , wherein the flip cover has a second inner side; the second extended portion of the flexible connecting element being extended onto and connected to the second inner side of the flip cover; and the second extended portion having a second contact surface facing away from the second inner side of the flip cover.

10. The protective device as claimed in claim 1 , wherein the carrier is a back base of the electronic device and is provided on the edges surrounding the first inner side with a plurality of clamping sections.

11. The protective device as claimed in claim 1 , wherein the edges of the first inner side of the carrier are respectively upwardly extended to form a protective wall, which has a free end inwardly bent to form a retaining edge, such that the first inner side, the protective walls and the retaining edges together define a receiving space to receive the electronic device therein.

12. A protective device capable of dissipating heat for protecting an electronic device, comprising:
a carrier for correspondingly connecting to or receiving the electronic device therein and having a first inner side oriented to the electronic device and a plurality of edges surrounding the first inner side;
a flexible connecting element being arranged at one of the edges of the carrier and having two opposite ends that respectively form a first and a second extended portion; the first extended portion being extended onto and partially across an upper surface of the first inner side of the carrier, the first extended portion being connected to the first inner side of the carrier, and the second extended portion being extended away from the carrier to form a flip cover, which can be turned towards or away from the carrier; and the first extended portion being in direct or indirect contact with at least one heat source of the electronic device,
wherein the flip cover has a second inner side; the second extended portion of the flexible connecting element being extended onto and connected to the second inner side of the flip cover; and the second extended portion having a second contact surface facing away from the second inner side of the flip cover,
wherein the flip cover is provided with an on-cover heat transfer element; the on-cover heat transfer element having a third and a fourth contact end, one of which being in contact with the second contact surface of the flexible connecting element.

13. The protective device as claimed in claim 12 , wherein the second contact surface of the flexible connecting element is the metal foil.
