For example, the connection plate 131 may be provided with a first notch for exposing the heat sink 150 and a second notch for forming an installation space of the battery 190.
The insulating heat-conducting member 140 is connected to the insulating support 130, and an orthographic projection of the insulating heat-conducting member 140 on the heat generating member 120 at least partially coincides with the heat generating member 120. The insulating heat-conducting member 140 is further connected to the heat sink 150, and the insulating heat-conducting member 140 transmits the heat generated by the heat generating member 120 to the heat sink 150.
The thermal conductivity of the insulating thermal conductive member 140 is greater than that of the insulating support 130, so that the thermal efficiency of the insulating thermal conductive member 140 is greater than that of the insulating support 130, and the heat dissipation of the heating member 120 can be accelerated by the insulating thermal conductive member 140, thereby reducing the temperature of the electronic device.
The dielectric constant of the material of the insulating and heat conducting member 140 is less than or equal to 5, and the heat conductivity coefficient of the insulating and heat conducting material is greater than or equal to 10W/m.degree. For example, the material of the insulating and heat-conducting member 140 may be h-BN (hexagonal boron nitride) or an intrinsic polymer having a highly ordered structure, such as a high crystallinity PE fiber woven film material. In the h-BN plane, B, N atoms form a graphite-like structure in an SP2 hybrid form, and the graphite-like structure has high heat conduction property.

For example, the insulating thermal conductive film is attached to an end of the insulating support 130 away from the heat generating element 120. Or the insulating heat conducting film is attached to the surface of the heat generating element 120 away from the main board 160.
In one possible embodiment of the present disclosure, as shown in fig. 4, the heat generating member 120 is located at one side of the insulating support 130, and the insulating heat conducting member 140 is located at the other side of the insulating support 130.

The insulating thermal conductive member 140 is in contact with the insulating support 130, for example, the insulating thermal conductive member 140 is directly connected to the insulating support 130, or the insulating thermal conductive member 140 and the insulating support 130 are connected by a heat dissipation adhesive. At this time, the heat dissipation path of the heat generated by the heat generating member 120 is: a heat generating member 120, an insulating support 130, an insulating heat conducting member 140, and a heat sink 150.
The orthographic projection of the insulating heat-conducting member 140 on the heat generating member 120 at least partially covers the heat generating member 120, so that the insulating heat-conducting member 140 can conduct the heat generating member 120 to the insulating support 130 for rapid heat absorption. The orthographic projection of the insulating heat-conducting member 140 on the heat sink 150 at least partially coincides with the heat sink 150, so that the heat on the insulating heat-conducting member 140 can be quickly conducted to the heat sink 150.
As an example, the orthographic projection of the insulating heat-conducting member 140 on the heat generating member 120 completely covers the heat generating member 120, and the heat generated by the heat generating member 120 can be quickly conducted to the insulating heat-conducting member 140 by the insulating support 130. The side of the heating element 120 away from the main board 160 is completely covered by the connecting plate 131, and the insulating heat-conducting element 140 covers the side of the connecting plate 131 away from the heating element 120.
It is understood that providing a conductor at a portion of the heat generating member 120 close to the antenna 110 may affect the communication performance of the antenna 110. Therefore, the heat dissipation can be performed by using the insulating support 130 and the insulating heat-conducting member 140 at the portion of the heating member 120 close to the antenna 110, and the heat dissipation can be performed by using the heat sink 150 at the portion of the heating member 120 far from the antenna 110.
For example, as shown in fig. 5, the heat generating member 120 has a first region and a second region, the second region is located on a side of the first region away from the antenna 110, the insulating support 130 is opposite to the first region, the heat sink 150 is opposite to the second region, and the insulating heat conducting member 140 is located on a side of the insulating support 130 away from the heat generating member 120.

The heat of the first region of the heat generating member 120 is conducted through the insulating heat conductive member 140, and the second region of the heat generating member 120 is directly connected through the heat sink 150 to dissipate the heat. On the one hand, the insulating heat-conducting member 140 can dissipate heat of the first area of the heating member 120 on the basis of ensuring the communication performance of the antenna 110, and on the other hand, the heat sink 150 dissipates heat of the second area of the heating member 120, so that the heat dissipation efficiency of the second area of the heating member 120 can be improved, and the temperature of the electronic device is further reduced.
In another possible embodiment of the present disclosure, as shown in fig. 6, a mounting through hole may be provided on the insulating support 130, and the mounting through hole may be provided in an orthographic projection area of the heat generating member 120 on the insulating support 130. The insulating heat-conductive member 140 may be mounted to the mounting through-hole such that the insulating heat-conductive member 140 contacts the heat generating member 120. At this time, the heat dissipation path of the heat generated by the heat generating member 120 is: a heating member 120, an insulating heat-conducting member 140, and a heat sink 150.
The insulating heat-conducting member 140 may partially cover the heat generating member 120 or completely cover the heat generating member 120, so that heat generated from the heat generating member 120 can be conducted to the insulating heat-conducting member 140. The insulating heat-conducting member 140 extends from the heat generating member 120 to the heat-dissipating heat sink 150, and the heat-dissipating heat sink 150 absorbs heat of the insulating heat-conducting member 140.
Illustratively, one end of the heat generating member 120 away from the main board 160 contacts the insulating heat conducting member 140, and the insulating heat conducting member 140 completely covers the surface of the heat generating member 120 away from the main board 160. The heat sink 150 is disposed at an end of the heat generating member 120 away from the antenna 110, an end of the insulating heat conducting member 140 away from the antenna 110 is connected to the heat sink 150, and the insulating heat conducting member 140 partially overlaps the heat sink 150.
It is understood that providing a conductor at a portion of the heat generating member 120 close to the antenna 110 may affect the communication performance of the antenna 110. Therefore, the heat dissipation can be performed by using the insulating support 130 and the insulating heat-conducting member 140 at the portion of the heating member 120 close to the antenna 110, and the heat dissipation can be performed by using the heat sink 150 at the portion of the heating member 120 far from the antenna 110.

The portion of the insulating support 130 corresponding to the second area is a hollow structure, and the heat sink 150 extends into the hollow structure and contacts with the second area of the heat generating member 120, for example, the second area of the heat generating member 120 may be directly connected to the heat sink 150, or the second area of the heat generating member 120 may be connected to the heat sink 150 through a heat dissipating adhesive.
The heat of the first region of the heat generating member 120 is conducted through the insulating heat conductive member 140, and the second region of the heat generating member 120 is directly connected through the heat sink 150 to dissipate the heat. On the one hand, the insulating heat-conducting member 140 can dissipate heat of the first area of the heating member 120 on the basis of ensuring the communication performance of the antenna 110, and on the other hand, the heat sink 150 dissipates heat of the second area of the heating member 120, so that the heat dissipation efficiency of the second area of the heating member 120 can be improved, and the temperature of the electronic device is further reduced.
