When the heat dissipation frame is cooled, the cover sleeve can be accommodated in the heat dissipation frame and seals the heat dissipation frame, so that dust and moisture are prevented from entering the heat dissipation frame. For example, in order to facilitate heat dissipation, a heat dissipation cavity is formed in the heat dissipation frame, and the cover is slidably disposed in the heat dissipation cavity. For example, the heat dissipation frame is a rectangular frame body, and the peripheral wall of the cover is slidably disposed on the side wall of the heat dissipation frame. For example, the heat dissipation frame includes the bottom plate and protruding locate the peripheral curb plate of bottom plate, the curb plate goes up the concave a plurality of sliding chutes that are equipped with, a plurality of sliding chutes are located in the heat dissipation cavity, the bottom surface of sliding chute is the arc, the cross section of sliding chute is half moon shape, the sliding chute runs through the bottom plate, and in form C shape hole on the bottom plate.

For example, in order to facilitate the abutting of the cover and the cover away from the heat dissipation frame, a plurality of abutting rods 64 are convexly arranged on the bottom plate of the heat dissipation frame, the abutting rods are cylindrical rods, and one end of the abutting rod away from the bottom plate is connected to the top plate of the cover and the cover. The diameter of the abutting rod is gradually reduced along the direction far away from the bottom plate. When heat in the heat dissipation frame increases, the support rod can extend to support and hold the cover and establish the cover and keep away from the heat dissipation frame and expose the heat dissipation cavity of heat dissipation frame, at this moment a plurality of slide bars also can keep away from gradually the bottom plate, and then expose a plurality of C shape holes on the bottom plate, and then make the hot-air in the heat dissipation cavity can follow the periphery of heat dissipation cavity and spill over in the C shape hole the heat dissipation cavity, then realize the radiating effect. For example, the support rod is made of memory alloy, and can extend and support the cover when heated. And when the cooling is performed, the heat dissipation frame can be contracted to the original shape, and the cover is arranged to cover the heat dissipation frame.
For example, in order to improve the heat dissipation effect of the heat dissipation frame, two heat dissipation blocks and two auxiliary plates are convexly arranged on the side plate, the two heat dissipation blocks are arranged oppositely, the two auxiliary plates are also arranged oppositely, and the central connecting line of the two heat dissipation blocks is perpendicular to the central connecting line of the two auxiliary plates. For example, the two heat dissipation blocks and the two auxiliary plates are rectangular blocks. The two auxiliary plates are both provided with a plurality of heat dissipation holes, and the heat dissipation holes are circular holes with the depth of 1.5-2.5 cm, such as 2 cm. The extending direction of the heat dissipation hole is perpendicular to the extending direction of the sliding rod. The auxiliary board is provided with a plurality of heat dissipation holes, so that the auxiliary board can dissipate heat as soon as possible. For example, in order to further improve the heat dissipation effect, the heat dissipation block is provided with a plurality of longitudinal holes and a plurality of transverse holes, the extending direction of the longitudinal holes is parallel to the extending direction of the sliding rod, and the extending direction of the transverse holes is perpendicular to the extending direction of the longitudinal holes. Because the radiating block is provided with a plurality of longitudinal holes and a plurality of transverse holes, the heat on the radiating block can be conveniently led out. For example, a first extending portion and a second extending portion are respectively formed on two sides of the side plate, and the first extending portion and the second extending portion are respectively located on two opposite sides of the heat dissipation block. For example, the first extending portion and the second extending portion are respectively located on the upper side and the lower side of the heat dissipation block, and the longitudinal hole extends to the first extending portion and the second extending portion and penetrates through the top surface and the bottom surface of the side plate. The longitudinal hole forms a first exposure groove on the first extension part, and the longitudinal hole forms a second exposure groove on the second extension part. The first exposure groove and the second exposure groove are exposed to the outside, so that the heat dissipation effect of the heat dissipation frame is improved. For example, the transverse bore communicates with two corresponding longitudinal bores, i.e. the transverse bore extends between and communicates with two longitudinal bores.
For example, in order to further improve the heat dissipation effect of the heat dissipation frame, a heat dissipation through hole 65 is formed in the top plate of the cover frame, the heat dissipation through hole is a circular hole, an ejector rod and a sealing block are convexly arranged on the heat dissipation frame, the ejector rod is convexly arranged on the bottom plate of the heat dissipation frame, the plurality of support rods surround the ejector rod, the ejector rod is made of memory alloy, and the deformation coefficient of the ejector rod is greater than that of the support rods. The sealing block is arranged at the top of the ejector rod and movably arranged in the heat dissipation through hole to seal the heat dissipation through hole. When the plurality of abutting rods are heated to extend and abut against the cover and the cover is far away from the heat dissipation frame, the ejector rod can extend and drive the sealing block to be separated from the heat dissipation through hole, so that the heat dissipation through hole on the cover can ventilate, and the heat dissipation effect is improved. Because the deformation coefficient of the ejector rod is greater than that of the support rod, the ejector rod can move faster when the cover moves in the process of establishing the cover, so that the ejector rod is separated from the cover to establish the cover. When the cover is arranged on the cover for cooling, the supporting rod and the ejecting rod can automatically contract, so that the sealing block returns to the heat dissipation through hole, and the heat dissipation through hole is sealed. For example, the closing block has a circular block shape in order to match the heat dissipation through hole.

The above embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
