In this embodiment, the cylinder 110 is a hollow cylinder. In other embodiments, the cylinder 110 is a hollow cuboid, a hollow truncated cone, or a hollow triangular prism. In various embodiments, to increase the heat dissipation rate, the cylinder 110 is made of an aluminum alloy material. In this embodiment, the hollow cylinder 110 is formed with a heat dissipation channel 111, and two sides of the cylinder 110 are opened to form a heat exhaust port 112 and a heat absorption port 113, respectively. In each embodiment, the heat dissipation channel 111 is circular, and the heat discharging opening 112 and the heat absorbing opening 113 are also circular. That is, the heat dissipation channel 111, the heat discharge opening 112, and the heat absorption opening 113 are maintained in a circular structure regardless of the external shape structure of the cylinder 110, so that a stable heat dissipation system is formed using the structure, thereby improving heat dissipation efficiency.

Referring to fig. 2, 4 and 5, the heat sink mounting plate 161 is mounted on the cylinder 110 and covers the heat sink 113. Specifically, the cylinder 110 is provided with a fastening portion 114, the heat dissipation mounting plate 161 is provided with a matching portion 164, and the fastening portion 114 is fastened and connected with the matching portion 164. In this embodiment, the fastening portion 114 is integrally disposed on the barrel 110, and the matching portion 164 is integrally disposed on the heat dissipation mounting plate 161, so that the fastening portion 114 and the matching portion 164 are firmly and stably configured, and the fastening portion 114 and the matching portion 164 are stably and firmly fastened. In this embodiment, the cylinder 110 is provided with a buckling portion 114 at a side of the heat absorbing opening 113. Correspondingly, the heat dissipating mounting plate 161 is provided with a matching portion 164 corresponding to the buckling portion 114. In order to more stably and firmly cover the heat sink mounting plate 161, the number of the fastening portions 114 is two, and correspondingly, the number of the matching portions 164 is two, and each fastening portion 114 is correspondingly fastened to one matching portion 164. Specifically, the cylinder 110 is provided with two buckling portions 114 at the side of the heat absorbing opening 113, and the heat dissipating mounting plate 161 is provided with a matching portion 164 at each buckling portion 114.

Further, the engaging portion 114 has a rectangular parallelepiped structure. The fitting portion 164 has a rectangular parallelepiped structure. The top end face of buckling part 114 is flush with the top end face of barrel 110, namely the top end face of buckling part 114 is coplanar with the top end face of barrel 110, so that after heat dissipation mounting disc 161 is installed on barrel 110 and covers heat absorbing opening 113, the bottom face of heat dissipation mounting disc 161 is abutted with the top end face of barrel 110, no gap exists between the bottom face of heat dissipation mounting disc 161 and the top end face of barrel 110, and therefore the ventilation order of air in air exhaust channel 234 and air inducing channel 243 is ensured, and more stable heat dissipation efficiency is kept. The engaging portion 114 is recessed at the top end surface to form a penetrating engaging channel 115, so that the engaging portion 114 is formed into a hollow rectangular parallelepiped structure with two open ends. The top end of the buckling passage 115 is opened adjacent to the heat absorbing port 113. For the convenience of inserting into the mating portion 164, the engaging channel 115 is also rectangular, and the shape of the engaging channel 115 matches the shape of the mating portion 164, that is, the length, width and height of the engaging channel 115 are equal to the length, width and height of the mating portion 164, so that the mating portion 164 can be slidably inserted into the engaging channel 115 and received in the engaging channel 115.

It can be understood that the whole thickness of the fitting part 164 increases after the limiting block 165 is arranged, and the fitting part 164 is difficult to be inserted into the buckling channel 115 in a sliding manner, and in order to solve the problem, the adopted scheme has two, one is: a limiting clamping groove (not shown) is formed in the surface of the matching portion 164, the structure of the limiting clamping groove is the same as that of the limiting block 165, the depth of the limiting clamping groove is larger than the height of the limiting block 165, the limiting block 165 is elastically accommodated in the limiting clamping groove, namely, the limiting block 165 can be completely accommodated in the limiting clamping groove after external force is applied, and can be ejected out of the limiting clamping groove after the external force is removed, so that when the matching portion 164 is slidably inserted into the buckling channel 115, when the limiting block 165 slides to the limiting notch 116, the external force of the buckling portion 114 on the limiting block 165 disappears, and the limiting block 165 is ejected out of the limiting clamping groove and clamped with the buckling portion 114, so that how to slide the matching portion 164 into the buckling channel 115 under the condition that the limiting. Secondly, the limiting block 165 is made of silica gel material, the limiting block 165 is adhered to the surface of the matching part 164 through strong adhesive, the width of the buckling channel 115 is slightly smaller than that of the matching part 164, the limiting block 165 is of a triangular prism structure shown in fig. 5, when the matching part 164 is inserted into the buckling channel 115 in a sliding mode, the limiting block 165 deforms, when the limiting block 165 slides to the limiting notch 116, the external force of the buckling part 114 on the limiting block 165 disappears, the deformation of the limiting block 165 is recovered, the limiting block 165 is clamped with the buckling part 114, and therefore the problem that how to enable the matching part 164 to slide into the buckling channel 115 under the condition that the limiting block 165 is arranged can be solved.
