As shown in the embodiment shown in FIG. 1, the heat dissipation casing 900 of the present invention is used by the electronic device 800. In one embodiment, the electronic device 800 is a camera device, that is, the heat sink case 900 and the camera device serving as the electronic device 800 together form a part of the camera device 1000. However, in different embodiments, the electronic device 800 may include, but is not limited to, a computing device (such as a central processing unit), a light-emitting device (such as LED), a display device (such as a liquid crystal display panel), and a storage device (such as a hard disk drive). ), energy storage devices (such as battery modules), communication devices, etc.

As shown in the embodiment shown in FIG. 1, the heat dissipation casing 900 includes a casing 100 and a heat conductor 200. The housing 100 includes an inner top surface 101 and an inner bottom surface 102. Furthermore, the housing 100 has an inner space 108 for accommodating the heat conductor 200 and other components. The top surface and the bottom surface of the inner space 108 are the inner top surface 101 and the inner bottom surface 102, respectively. Among them, the housing 100 preferably has considerable mechanical strength and shielding properties to protect the thermal conductor 200 and other components contained in the internal space 108 from damage by external forces, and reduce oxidation, corrosion, and corrosion caused by dust, moisture, air, animals and plants. Short circuit.

The heat conductor 200 has elasticity. The elasticity referred to here generally refers to the ability to deform to a certain degree, that is, the material deforms under stress and returns to its original shape after the stress is removed. In other words, the heat conductor 200 as a whole is not rigid. The top surface 201 of the heat conductor 200 is in contact with the inner top surface 101. Wherein, when the electronic device 800 is disposed between the thermal conductor 200 and the inner bottom surface 102, the top side 801 of the electronic device 800 is in contact with the bottom surface 202 of the thermal conductor 200. More specifically, when the electronic device 800 has not been disposed between the heat conductor 200 and the inner bottom surface 102, the heat conductor 200 is not stressed and has the original thickness H200, and the bottom surface 202 of the heat conductor 200 and the inner bottom surface 102 have a distance D . Because the thermal conductor 200 is elastic, if the distance D is slightly smaller than the height H800 of the electronic device 800, when the electronic device 800 is placed between the thermal conductor 200 and the inner bottom surface 102, the thermal conductor 200 will be squeezed by the electronic device 800 to increase its thickness. The H200 becomes smaller, so that the bottom surface 202 of the thermal conductor 200 and the side surface 801 of the electronic device 800 are kept in contact, which facilitates the conduction of the heat generated by the operation of the electronic device 800 away from the electronic device 800.

Viewed from different angles, when the electronic device 800 is disposed on the inner bottom surface 102, the lower elastic thermally conductive layer 220 is located between the thermal container 230 and the electronic device 800, and its elasticity allows the bottom surface of the lower elastic thermally conductive layer 220 to be connected to the electronic device 800. The side 801 of the side surface 801 is kept in contact, which facilitates the conduction of heat generated by the operation of the electronic device 800 away from the electronic device 800. Wherein, the heat capacity body 230 is selected from the group consisting of one or a combination of aluminum metal, copper metal, and silver metal. Other metals can also be selected, which can be used as heat capacity to be derived from the electronic device through the lower elastic heat-conducting layer, but not And the heat energy transferred from the casing 100 to the external environment is temporarily stored, that is, it has a buffering effect.

As shown in the embodiment shown in FIG. 2B, the heat conductor 200 may further include an elastic heat conduction layer 210 disposed on the top side 231 of the heat container 230, wherein the upper elastic heat conduction layer 210 is opposite to the other side and inner side of the heat container 230. The top surface 101 touches. Viewed from a different perspective, when the electronic device 800 is disposed on the inner bottom surface 102, and the lower elastic heat conducting layer 220 is located between the heat container 230 and the electronic device 800, the upper elastic heat conducting layer 210 is located on the inner top surface 101 and the heat container Between 230, the top surface and bottom surface of the upper elastic heat conducting layer 210 are in contact with the inner top surface 101 of the housing 100 and the top side 231 of the heat container 230 respectively due to its elasticity, which is beneficial to heat conduction of the heat container 230 To the housing 100 to further dissipate heat to the external environment. In a preferred embodiment, the upper elastic heat dissipation layer and the lower elastic heat dissipation layer include but are not limited to diamond-like carbon materials.

Among them, the composition of the heat dissipation coating 300 is selected from a combination of high-resolution resin, solvent, titanium dioxide, silicon dioxide, silicon-based compound, and diamond-like carbon compound, of which the diamond-like carbon compound is carbon (50%~60%) , Silicon (20%~30%), Germanium (10%~20%).

As shown in the embodiment shown in FIG. 4, the heat dissipation casing 900 further includes a shield 400 disposed above the heat dissipation coating 300. In this way, the accumulation of dust on the heat dissipation coating 300 can be reduced, resulting in a decrease in the heat dissipation effect. Furthermore, the shield 400 can also reduce the temperature of the housing 100 due to sunlight. Furthermore, the vertical projection of the mask 400 on the outer top surface 103 covers the heat dissipation coating 300. In other words, the top of the heat dissipation coating 300 is preferably shielded by the mask 400.

The following tests are performed on the conventional imaging device and the imaging device of the embodiment shown in FIGS. 2B and 3.
