Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 to 5, the present invention firstly provides a heat dissipation assembly applied between an electronic device 1 and a shield 2, wherein: the protective cover 2 is used for separating the electronic device 1 from the external environment to achieve the protection functions of dust prevention, water prevention, sun protection and the like, and heat emitted outwards when the electronic device 1 works can be emitted outwards through the protective cover 2.
As shown in fig. 4 and 5, the heat dissipation device includes a bottom plate 3 for mounting the electronic device 1, a first heat conduction member 4 and a second heat conduction member 5, the first heat conduction member 4 is sandwiched between the bottom plate 3 and the second heat conduction member 5 and has a certain elastic deformation capability, when the bottom plate 3 is fixedly mounted on the shield 2, the first heat conduction member 4 is pressed between the bottom plate 3 and the second heat conduction member 5 and elastically deforms, so that the second heat conduction member 5 is elastically pressed against the attached shield 2 by the elastic force. Like this, the heat that electronic equipment 1 during operation outwards gived off at first conducts to bottom plate 3 on, then transmit to with bottom plate 3 direct contact and can heat conduction on first heat-conducting piece 4, because the elastic deformation of first heat-conducting piece 4, make bottom plate 3 and second heat-conducting piece 5 all reliably contact with first heat-conducting piece 4, the heat is reliably conducted to second heat-conducting piece 5 on, simultaneously, because second heat-conducting piece 5 elasticity supports and presses on guard shield 2, laminating between the two makes the heat of second heat-conducting piece 5 can effectively conduct to guard shield 2, so, from electronic equipment 1 to guard shield 2, the heat conduction is reliable, the conduction efficiency is high, be favorable to realizing the outside radiating process of electronic equipment 1 through guard shield 2.
In some embodiments, the first thermal conductive member 4 is provided as a combination of one or more of a thermal pad, a thermal foam, and a thermal silicone grease. The first heat-conducting member 4 may be a plate-like or block-like structure formed by prefabricating the above-mentioned materials and then installed between the bottom plate 3 and the second heat-conducting member 5, or may be formed by primarily connecting the second heat-conducting member 5 and the bottom plate 3, filling the first heat-conducting member, and then solidifying the first heat-conducting member and the second heat-conducting member. The second heat conducting member 5 may be a rigid heat conducting medium, such as a metal block, a sheet metal member, or a heat pipe, and may also be an elastic heat conducting medium similar to the first heat conducting member 4.
A mounting cavity 20 is formed in the shield 2, a boss 21 for supporting the base plate 3 is provided in the mounting cavity 20, and the base plate 3 and the boss 21 are connected by a fastening screw 7. When the heat sink is mounted, the edge of the bottom plate 3 is overlapped on the boss 21, and after the relative position of the bottom plate 3 is adjusted, the fastening screw 7 is screwed into the boss 21, so that the first heat-conducting member 4 and the second heat-conducting member 5 are arranged between the bottom plate 3 and the inner bottom surface of the mounting chamber 20.
