Referring to fig. 2 and fig. 3, fig. 2 shows a schematic partial cross-sectional structure of a cabinet in an embodiment of the present application, and fig. 3 shows a schematic cross-sectional structure of a cabinet in an embodiment of the present application, in which an electronic device 2 is disposed inside the cabinet and has at least one cabinet heat sink 3, and the cabinet heat sink 3 includes an inner side wall 31 and an outer side wall 32 of the cabinet, that is, the side wall of the cabinet is a hollow structure, the side of the hollow structure facing the inside of the cabinet is the inner side wall 31, and the side facing the outside of the cabinet is the outer side wall 32. Referring to fig. 4 and fig. 5, fig. 4 shows a schematic cross-sectional structure of the cabinet radiator 3 along a direction perpendicular to the outer sidewall 32 in the embodiment of the present application, fig. 5 shows a schematic cross-sectional structure of the cabinet radiator 3 along a direction parallel to the outer sidewall 32 in the embodiment of the present application, the hollow structure has a plurality of heat exchanging fins 33, the heat exchanging fins 33 are connected between the inner sidewall 31 and the outer sidewall 32, the plurality of heat exchanging fins 33 divide the inner sidewall 31 and the outer sidewall 32 into a plurality of inner circulating air channels 34 and a plurality of outer circulating air channels 35, the inner circulating air channels 34 and the outer circulating air channels 35 are sequentially arranged at intervals, each inner circulating air channel 34 includes an inner air inlet 341 and an inner air outlet 342, and each outer circulating air channel 35 includes an outer air inlet 351 and an outer air outlet 352. When the cabinet radiator 3 works, air with higher temperature inside the cabinet enters the internal circulation air duct 34 from the internal air inlet 341, flows in the internal circulation air duct 34 and flows out from the internal air outlet 342, fresh air with lower temperature outside the cabinet enters the external circulation air duct 35 from the external air inlet 351, flows in the external circulation air duct 35 and flows out from the external air outlet 352, and therefore the air in the internal circulation air duct 34 and the air in the external circulation air duct 35 exchange heat through the heat exchange fins 33 between the internal circulation air duct 34 and the external circulation air duct 35, heat inside the cabinet is taken out by the external fresh air and is exhausted to the outside of the cabinet, and in order to improve the heat dissipation effect, the flowing direction of the air in the internal circulation air duct 34 is opposite to the flowing direction of the air in the external circulation air duct 35. In addition, the internal circulation air duct 34 of the cabinet radiator 3 is isolated from the outside by the outer side wall 32, so that the air with high temperature in the internal circulation air duct 34 can be radiated by the outer side wall 32. Therefore, in the embodiment of the present application, on the one hand, the internal circulation air duct 34 and the external circulation air duct 35 which are spaced in sequence can be utilized for heat exchange and heat dissipation, on the other hand, the outer side wall 32 of the internal circulation air duct 34 can be utilized for direct contact with the outside, heat dissipation is performed, and the heat dissipation efficiency is high.

Specifically, referring to fig. 5, the inner circulation air duct 34 and the outer circulation air duct 35 extend in a direction perpendicular to the ground, when the cabinet radiator 3 is in use, the temperature of the air inside the cabinet is high, and since the density of the hot air is lower than that of the cold air, the density of the hot air inside the cabinet is above, and the density of the air increases and the air decreases as the temperature decreases, so that the inner air inlet 341 of the inner circulation air duct 34 can be located above, the inner air outlet 342 of the inner circulation air duct 34 is located below, where above refers to a direction away from the ground, and below refers to a direction close to the ground. In addition, the distance between the inner air inlet 341 and the inner air outlet 342 should be kept as large as possible, and specifically, the inner air inlet 341 and the inner air outlet 342 may be respectively located at two ends of the internal circulation air duct 34, so as to increase the path of air heat exchange and improve the heat dissipation effect. The inner circulation air duct 34 and the outer circulation air duct 35 extend in the direction perpendicular to the ground, which is beneficial to reducing the resistance of air flow, promoting air flow and improving heat exchange efficiency.
When the cabinet radiator 3 is specifically arranged, the air flow direction in the circulating air duct 34 should be opposite to the fresh air flow direction in the external circulating air duct 35, so as to improve the heat exchange efficiency between the air in the cabinet and the fresh air outside.

When the cabinet radiator 3 is specifically prepared, the cabinet radiator can be prepared by metal, so that the cabinet has a good radiating effect. More specifically, the cabinet radiator 3 can be manufactured into an aluminum extrusion molding structure, so that the manufacturing process is simple, the cost is low, the aluminum extrusion heat conduction effect is good, and the improvement of the heat dissipation effect is facilitated.
