second air inlets

141 and 142. Then, a part of the cold air on the left side of the hard disk assembly 5 passes through the hard disk assembly 5 from left to right under the action of the hard disk fan 68 to cool the hard disk assembly 5, and the air passing through the hard disk assembly 5 and the cold air entering through the first air inlet 141 enter the heat dissipation area 132 through the first through hole 211 under the action of the system fan 67; part of the air enters the GPU70 through the air duct 71 to ventilate and dissipate heat of the GPU70, and finally is discharged out of the cabinet 1 through the first exhaust hole 1521; a part of the air passes through the insertion groove 65, ventilates and dissipates heat of the expansion card on the insertion groove 65, and finally is exhausted out of the casing 1 through the second exhaust hole 1522; in addition, a part of the wind passes through the corresponding radiator 63 under the guidance of the heat radiation fan on the first heat source 61 to achieve the purpose of radiating the first heat source 61 by ventilating and radiating the radiator 63, the wind passing through the radiator 63 on the first heat source 61 flows to the right rear of the second heat source 62 under the guidance of the first air deflector 31 to bypass the second heat source 62 and the radiator 63 on the second heat source 62, and finally is discharged out of the cabinet 1 through the third exhaust hole 1523 and the top exhaust hole 151. The other part of the cool air on the left side of the hard disk assembly 5 enters the heat dissipation area 132 through the second via hole 212, the cool air entering the heat dissipation area 132 through the second via hole 212 is divided into two parts under the action of the power supply fan and the heat dissipation fan on the second heat source 62 and under the action of the fifth air deflector 42, one part of the cool air flows to the power supply module 69 and is exhausted out of the enclosure 1 through the fourth exhaust hole 1524 after dissipating heat to the power supply module 69, the other part of the cool air flows to the corresponding heat sink 63 under the common limitation of the first air deflector 3 and the second air deflector 4 so as to achieve the purpose of dissipating heat to the second heat source 62 by ventilating and dissipating heat to the heat sink 63, and the air passing through the heat sink 63 on the second heat source 62 is finally exhausted out of the enclosure 1 through the third exhaust hole 1523 and the top exhaust hole 151.

The heat dissipation case provided by this embodiment can effectively separate the air inlet and outlet paths of the two sets of radiators 63 by arranging the first air guide 3 and the second air guide 4, so that the air outlet end of the front set of radiators 63 bypasses the air inlet end of the rear set of radiators 63, and the influence of hot air exhausted by the front radiators 63 on the CPU on the rear is avoided. The air intake end of the rear radiator 63 is additionally supplied from other regions in the turning direction of the first air guide 3 and the second air guide 4, and is no longer in an interaction relationship with the front radiator 63 on the air passage. In addition, the air guide pipe 71 is arranged, so that a channel for independently ventilating and radiating the GPU70 is formed, the GPU70 can be ensured to radiate smoothly, the GPU70 can keep good working performance, the aging speed of the GPU70 is reduced, and the service life of the GPU70 is prolonged. In addition, the air inlet holes 14 are formed on the left and right sides of the cabinet, so that more devices and device interfaces can be mounted on the front panel 111. In addition, the partition plate 2 not only can support the system fan 67, but also can prevent the wind with heat in the heat dissipation area 132 from flowing back to the air inlet ends of the system fan 67 and the hard disk fan 68, so as to reduce the heat dissipation efficiency of the devices in the casing 1.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
