The heat generating element 140 is also disposed in the receiving space S1, and the heat pipe 150 is disposed in the gap G1 between the battery module 130 and the arc surface 112 and thermally coupled to the heat generating element 140.
In this configuration, since the housing 110 of the embodiment is an arc-shaped housing, the inner surface of the housing is the arc-shaped surface 112, and the upper surface of the battery module 130 is a plane, a gap G1 is formed between the arc-shaped surface 112 and the upper surface of the battery module 130 as shown in fig. 1, and the heat pipe 150 can be disposed in the gap G1, so that the heat pipe 150 can be disposed in the portable electronic device 100 of the embodiment without additionally increasing the overall thickness, thereby improving the heat dissipation efficiency of the portable electronic device 100 and further improving the space utilization rate in the portable electronic device 100.
Further, the portable electronic device 100 may further include a circuit board 160 and a display module 170, wherein the circuit board 160 is disposed in the accommodating space S1, and the heating element 140 may be, for example, a central processing unit of the portable electronic device 100, and is disposed on the circuit board 160. The number of the heat generating elements 140 of the present embodiment may be multiple, and all of the heat generating elements are disposed on the circuit board 160 and thermally coupled to the heat pipe 150. The display module 170 is disposed in the accommodating space S1 and located between the cover plate 120 and the battery module 130. In the embodiment, the cover 120 may be, for example, a transparent glass cover, and may also have a touch function, which covers the display module 170 to provide protection, so that a user can see the image displayed by the display module 170 through the transparent cover 120.
In this embodiment, the circuit board 160 and the heating element 140 thereon may also be disposed in the gap G1 between the housing 110 and the battery module 130. Specifically, the circuit board 160 may be disposed between the battery module 130 and the heat pipe 150 as shown in fig. 1, such that the heat pipe 150 is thermally coupled to the heat generating element 140 on the circuit board 160. In this embodiment, the battery module 130 may abut against the arc-shaped surface 112 of the housing 110, and the upper surface of the battery module 130 and the arc-shaped surface 112 of the housing 110 define the gap G1, and the heat pipe 150, the circuit board 160 and the heat generating element 140 thereon are disposed in the gap G1.
Referring to fig. 3 and 4, unlike the embodiment of fig. 1 and 2, in the present embodiment, the circuit board 160 is adjacent to the side surface of the battery module 130 as shown in fig. 4, and further, the circuit board 160 may be substantially disposed in the accommodating space S1 in a coplanar manner with the battery module 130. Under this configuration, the battery module 130 further includes an extension portion 132 protruding from the upper surface 136 of the battery module 130 as shown in fig. 3, the extension portion 132 and the upper surface 136 of the battery module 130 define a step groove 134, and the top surface 138 of the extension portion 132 of the battery module 130 and the arc-shaped surface 112 of the housing 110 together define a gap G1, and the heat pipe 150 of the embodiment is disposed in the gap G1 and extends transversely to the circuit board 160 to form a thermal coupling with the heat generating element 140 disposed on the circuit board 160.
With such a configuration, since the circuit board 160 is adjacent to the side surface of the battery module 130 rather than being stacked above the battery module 130, the battery module 130 may be provided with the extension portion 132 extending toward the direction of the arc-shaped surface 112, so as to increase the volume of the battery module 130 without affecting the overall thickness of the portable electronic device 100a, thereby increasing the battery capacity thereof, and further increasing the endurance of the portable electronic device 100a during use. Moreover, the heat pipe 150 may be disposed in the gap G1 between the arc surface 112 of the casing 110 and the top surface 138 of the extension portion 132, so that the heat pipe 150 may be disposed in the portable electronic device 100a of the present embodiment without increasing the overall thickness, thereby improving the heat dissipation efficiency of the portable electronic device 100a and improving the space utilization rate in the portable electronic device 100 a.

Referring to fig. 5, unlike the embodiment of fig. 3 and 4, in the present embodiment, the battery module 130 also includes an extension portion 132 protruding from a surface of the battery module 130 to define a stepped groove 134. However, in the present embodiment, the surface and the step groove 134 face the cover plate 120. That is, the extension 132 of the present embodiment protrudes from the surface of the battery module 130 facing the cap plate 120 to define the stepped groove 134 facing the cap plate 120. The heat pipe 150 is disposed in the stepped groove 134 and thermally coupled to the heat generating element. In this embodiment, the housing 110 may not need to be an arc-shaped housing.
In the present embodiment, the circuit board may be adjacent to the side surface of the battery module 130 in a similar configuration as shown in fig. 4, and the heat generating element is disposed on the circuit board. That is, the circuit board of the present embodiment may be substantially coplanar with the battery module 130 and disposed in the accommodating space S1, and the heat pipe 150 disposed in the stepped groove 134 of the battery module 130 may extend transversely to the circuit board to form a thermal coupling with the heat generating element. Of course, this embodiment is only for illustration, and in other embodiments, the circuit board may be stacked on the battery module 130 in a similar configuration as that of fig. 2, and the invention is not limited to the configuration of the circuit board and the thermal coupling between the heat pipe 150 and the heat generating element.
So configured, the present embodiment utilizes the stepped design of the battery module 130 to dispose the heat pipe 150 in the stepped groove 134 of the battery module 130.

In the present embodiment, the surface and the stepped groove 134 face the housing 110, and the top surface of the extension 132 can abut against the arc surface 112 of the housing 110. That is, the extension 132 of the present embodiment protrudes from the surface of the battery module 130 facing the housing 110 to define the stepped groove 134 facing the housing 110. The heat pipe 150 is disposed in the stepped groove 134 facing the case 110 and thermally coupled with the heat generating element.
In the present embodiment, the circuit board may be adjacent to the side surface of the battery module 130 in a similar configuration as shown in fig. 4, and the heat generating element is disposed on the circuit board. That is, the circuit board of the present embodiment may be substantially coplanar with the battery module 130 and disposed in the accommodating space S1, and the heat pipe 150 disposed in the stepped groove 134 of the battery module 130 may extend to the circuit board to be thermally coupled to the heat generating element.
Under such a configuration, the battery module 130 of the embodiment is provided with the extension portion 132 extending toward the arc surface 112 of the housing 110, so as to increase the volume of the battery module 130 without affecting the overall thickness of the portable electronic device 100c, thereby increasing the battery capacity thereof, and further increasing the endurance of the portable electronic device 100a during use. Moreover, in the present embodiment, the stepped groove 134 defined by the extension portion 132 of the battery module 130 is further utilized to accommodate the heat pipe 150, so that the heat pipe 150 can be disposed in the portable electronic device 100c of the present embodiment without additionally increasing the overall thickness, thereby improving the heat dissipation efficiency of the portable electronic device 100c and improving the space utilization rate in the portable electronic device 100 c.
In addition, in the present embodiment, the stepped grooves 134 of the battery module 130 may be symmetrically disposed as shown in fig. 4, so that the top profile of the battery module 130 approaches a symmetrical curved surface. Thus, the appearance of the casing 110 covering the battery module 130 can be smoothly curved to conform to the ergonomic design, thereby improving the holding feeling of the portable electronic device 100 c.
In summary, the casing of the portable electronic device of the present invention has the arc-shaped surface, so a gap is formed between the arc-shaped surface of the casing and the upper surface of the battery module, and the heat pipe can be disposed in the gap. In addition, the battery module of the portable electronic device can also adopt a step-shaped design, and the heat pipe is arranged in the step groove of the battery module. Therefore, the portable electronic device can be provided with the heat pipe under the condition of not additionally increasing the whole thickness, thereby improving the heat dissipation efficiency of the portable electronic device and improving the space utilization rate in the portable electronic device.
