As shown in fig. 1-3, embodiments provided for by the present utility model.
The embodiment of the utility model provides a heat dissipation structure of a mini host, which comprises the following components: a housing 10, a base plate 20, a centrifugal fan 30, and a heat dissipation assembly 40; the casing 10 has a cavity therein, the base plate 20 is installed in the cavity, and the centrifugal fan 30 and the heat dissipation assembly 40 are respectively connected to the base plate 20; a plurality of vent holes 11 communicated with the cavity are respectively arranged on two sides of the shell 10; the heat dissipation assembly 40 comprises a plurality of heat dissipation fins 41 which are arranged in parallel, all the heat dissipation fins 41 are respectively connected with the bottom plate 20, every two adjacent heat dissipation fins 41 are formed with heat dissipation grooves 42 at intervals, and the heat dissipation grooves 42 are communicated with the ventilation holes 11; the middle part of the heat radiation assembly 40 is provided with an avoidance groove 43, the centrifugal fan 30 is positioned in the avoidance groove 43, and the air outlet end of the centrifugal fan 30 is communicated with the vent hole 11 through the heat radiation groove 42.
In the embodiment of the present utility model, the casing 10 is a square box-shaped host casing, the cavity inside the casing 10 can accommodate the installation of the bottom plate 20, the centrifugal fan 30 and the heat dissipation component 40, the heat dissipation component 40 is directly connected with the bottom plate 20, so that heat conduction between the two is facilitated, and the bottom plate 20 is usually arranged next to the main board 50 or the CPU and other components with relatively serious heat in the host, so that heat generated is conveniently conducted in time, and therefore, the main board 50 or the CPU is cooled. A plurality of ventilation holes 11 are formed in two sides of the shell 10, and are used for communicating air in the shell 10 with the outside, so that heat can be conveniently dissipated. Of course, the housing 10 may be made of a metal material with good heat conductivity, so that heat in the housing 10 can be directly dissipated through the housing 10 itself. The heat dissipation assembly 40 and the centrifugal fan 30 are main heat dissipation mechanisms, and a plurality of parallel heat dissipation fins 41 are uniformly distributed on the surface of the bottom plate 20, so that the bottom edges of all the heat dissipation fins 41 are connected with the bottom plate 20, the heat of the bottom plate 20 can be quickly transferred to each heat dissipation fin 41, heat dissipation grooves 42 are formed between two adjacent heat dissipation fins 41 at intervals, the surface of each heat dissipation fin 41 is fully contacted with air, and the heat emitted by the heat dissipation fins is discharged out of the shell 10 along the heat dissipation grooves 42 through the ventilation holes 11, so that heat dissipation is realized. In order to further enhance the heat dissipation effect, a centrifugal fan 30 is provided to accelerate the flow of air in the housing 10, so that air heated by heat emitted from the heat dissipation assembly 40 can be rapidly exchanged with outside air, thereby achieving rapid cooling. Specifically, the centrifugal fan 30 is directly embedded between the radiator fins, namely, the middle of part of the radiating fins 41 is cut off to form an avoidance groove 43 which just can accommodate the centrifugal fan 30 at the middle of all the radiating fins 41 arranged and distributed, so that the centrifugal fan 30 can be hidden between the radiating fins 41, and the position originally occupied by the centrifugal fan 30 is avoided, thereby reducing the whole volume of the radiating structure; meanwhile, in order to enable the centrifugal fan 30 to better form a fit with the heat dissipation assembly 40, the air outlet end of the centrifugal fan 30 is aligned to the port of the heat dissipation groove 42, namely, the air outlet direction of the centrifugal fan 30 is consistent with the direction of the heat dissipation groove 42, air generated by the centrifugal fan 30 can be directly blown out through the heat dissipation groove 42 and then discharged to the outside of the shell 10 from the vent hole 11, and thus, heat emitted by the heat dissipation fins 41 can be blown away more effectively, and the bottom plate 20, the main board 50, the CPU and the like are cooled down rapidly.
In one embodiment, a protective housing 31 is disposed outside the centrifugal fan 30, the centrifugal fan 30 is horizontally mounted in the protective housing 31, air inlets 32 adapted to the centrifugal fan 30 are disposed at the bottom and top of the protective housing 31, and air outlets 33 are disposed at one side of the protective housing 31.
In this embodiment, in order to support and protect the main body of the centrifugal fan 30, the centrifugal fan 30 is horizontally installed in the protective housing 31, the protective housing 31 is directly installed in the avoidance groove 43, unlike the conventional centrifugal fan, which adopts an axial air-out mode, and the heat dissipation component needs to be blown in front of the air-out end or sucked in behind the air-out end, so that a certain space is formed between the heat dissipation component and the centrifugal fan, which results in a larger occupied space of the whole heat dissipation structure, and the air flow driven by the centrifugal fan in unit time is smaller in a mode of air intake at one end, which results in lower heat dissipation efficiency, while the centrifugal fan 30 in this embodiment uses centrifugal force to form negative pressure to suck air from the air inlets 32 at the upper end and the lower end of the protective housing 31, which can increase the air intake, and then blow out from the air outlet 33 at one side of the protective housing 31, which also enhances the air pressure of the air-out, and can further promote the overall cooling efficiency.
In one embodiment, a spacer 431 is disposed at the bottom of the avoidance groove 43, and the spacer 431 is connected to the bottom of the protection shell 31 and is used for elevating the air inlet 32 at the bottom of the protection shell 31.

In one embodiment, the location of each vent 11 corresponds to the location of a heat sink 42.
In this embodiment, the positions of the vent holes 11 are in one-to-one correspondence with the ports of the heat dissipation grooves 42, so that the exchange of air inside and outside the housing 10 is smoother, and the air flow generated by the centrifugal fan 30 can be directly blown out of the housing 10 along the heat dissipation grooves 42, so that the distance required by the air flow is shortened, and the heat dissipation efficiency can be improved.
In one embodiment, the housing 10 is provided with a removable metal cover plate 12, the cover plate 12 being in covering connection with the housing 10. The surface of the cover plate 12 is provided with a plurality of bar-shaped grooves 121.
