The power module 200 has a first ventilation opening 2211 and a second ventilation opening 2212, and a first fan 230 is disposed at the first ventilation opening 2211. The first chamber 110 and the second chamber 120 are arranged inside the box body 100, the power module 200 is arranged in the first chamber 110, the third vent and the fourth vent 121 are arranged on the wall of the second chamber 120, the third vent is communicated with the second vent 2212, and the size of the fourth vent 121 is larger than that of the first vent 2211. The first fan module 300 is connected to the cabinet 100 and includes a second fan 310, and the second fan 310 corresponds to the fourth air outlet 121 and is configured to discharge air in the first chamber 110 through the fourth air outlet 121.

Specifically, the box 100 includes a first side plate 130, a second side plate 140, a partition 150, a third side plate 160, a top plate 180, and a bottom plate 170, where the top plate 180 and the bottom plate 170 are located at upper and lower ends of the chassis. The first side plate 130, the second side plate 140, the third side plate 160 and the partition 150 are connected between the top plate 180 and the bottom plate 170, and the first side plate 130 and the second side plate 140 are disposed opposite to each other. In the horizontal direction, one end of the third side plate 160 is connected to the first side plate 130, and the other end is connected to the second side plate 140. One end of the partition 150 is connected to the first side plate 130, and the other end is connected to the second side plate 140, and the partition 150 is connected to the middle positions of the first side plate 130, the second side plate 140, the bottom plate 170, and the top plate 180, and is spaced apart from the third side plate 160. The partition 150, the first side plate 130, the second side plate 140, the bottom plate 170, and the top plate 180 define the first chamber 110 with the partition 150. The partition 150, the first side plate 130, the second side plate 140, the third side plate 160, the bottom plate 170 and the top plate 180 define a second chamber 120, a third ventilation opening is formed at the bottom of the partition 150, and the second ventilation opening 2212 of the power module 200 is in sealed communication with the third ventilation opening (not shown) of the second chamber 120.

It should be noted that, in the drawings, the arrangement of the fourth air vent 121 on the first side plate 130 cannot be interpreted as the only limitation to the present application, and the fourth air vent 121 can also be opened on the second side plate 140, the third side plate 160 and the top plate 180, only that the size of the fourth air vent 121 is larger than that of the first air vent 2211, and that the air in the second chamber 120 can be exhausted out of the chassis through the fourth air vent 121.

In the conventional art, the chassis usually adopts power module 200 to supply power, and conventional power module sets up the power and is used for the radiating radiator fan of power in inside, however, power module 200's miniaturization makes power module 200 inner space narrow and small, consequently can't install the larger size radiator fan, leads to power module 200's heat-sinking capability to be restricted, and under the operation of high power, radiator fan is difficult to satisfy the heat dissipation demand to be difficult to carry out the business scene of high exchange, high calculation. In the case of this embodiment, the rear end (at the second ventilation opening 2212 in this embodiment) of the power module 200 is provided with a second chamber 120 communicated with the second ventilation opening 2212, and two side walls of the second chamber 120 are provided with fourth ventilation openings 121. The size of the fourth ventilation opening 121 is larger than that of the first ventilation opening 2211, and thus the second fan 310 having a size larger than that of the first fan 230 can be disposed at the fourth ventilation opening 121 with respect to the first ventilation opening 2211. So that the discharge amount of the second fan 310 is greater than that of the first fan 230 at the same time. Since the second cavity 120 is communicated with the second ventilation opening 2212 of the power module 200, the second fan 310 can increase the air flowing speed inside the power module 200, so as to improve the heat dissipation efficiency of the power module 200. Because the requirement of the multi-service board 400 on the total power of the power supply 210 is higher, the heat dissipation capability of the power supply module 200 is improved, and the requirement of high power operation can be met, so that the requirement of high heat dissipation performance brought by the scenes of high-density and high-power-consumption chips of the chassis is met.

Referring to fig. 2, fig. 4 and fig. 5, based on the above embodiments, the chassis further includes a service board 400, the power module 200 includes a power accommodating casing 220 and a power supply 210, a third cavity 221 is disposed inside the power accommodating casing 220, the first ventilation opening 2211 and the second ventilation opening 2212 are located on a cavity wall of the third cavity 221, the service board 400 and the power accommodating casing 220 are both located in the first cavity 110, and the third cavity 221 and the first cavity 110 are separated from each other due to the power accommodating casing 220, so that heat radiated by the power supply 210 and the service board 400 during operation is not affected by each other.

Specifically, the second chamber 120 and the first chamber 110 are interpreted independently as: the second chamber 120 and the first chamber 110 do not communicate with each other. Therefore, the heat generated by the power supply 210 and the heat generated by the service board 400 can be isolated, and the heat generated by the power supply 210 can be prevented from entering the first chamber 110, which causes the temperature of the service board 400 to increase and affects the performance of the service board 400.

Referring to fig. 4 and 5, on the basis of the above embodiment, the first chamber 110 is further provided with a fifth ventilation opening 111, the first fan module 300 further includes a third fan 320, and the third fan 320 is disposed at the fifth ventilation opening 111 and is used for exhausting air in the first chamber 110. Specifically, the fifth ventilation opening 111 can exhaust the air in the first chamber 110 to the outside of the chassis, so as to quickly exhaust the heat generated by the service board 400, and avoid the performance of the service board 400 being affected by an excessively high temperature.

It should be noted that, the fact that the fifth ventilation opening 111 is disposed on the first side plate 130 in the drawings is not to be construed as the only limitation of the present application, and the fifth ventilation opening 111 may also be disposed on the second side plate 140 and the top plate 180, as long as the air in the first chamber 110 can be exhausted outside the box body 100 through the fifth ventilation opening 111.

Referring to fig. 4 and 5, in some embodiments, the chassis further includes a second fan module 500 connected to the box 100, the second fan module 500 includes a fourth fan 510, the fourth air opening 121 faces the horizontal direction, a sixth air opening 122 is further disposed on a side wall of the second chamber 120 opposite to the fourth air opening 121, and the fourth fan 510 is disposed at the sixth air opening 122.

Specifically, the second side plate 140 is further provided with a sixth air vent 122, and the fourth fan 510 is disposed at the sixth air vent 122, it can be understood that there are two blowing modes for the fourth fan 510:

first, when the fourth fan 510 and the second fan 310 both discharge the air in the second chamber 120, the discharge speed of the air in the first chamber 110 can be increased by the combined operation of the fourth fan 510 and the second fan 310, so as to increase the flowing speed of the air in the power module 200 and increase the heat dissipation speed of the power module 200.

Second, when the air outlet directions of the fourth fan 510 and the second fan 310 are the same, that is, the fourth fan 510 blows air towards the second fan 310, and the fourth fan 510 and the second fan 310 cooperate to generate high-speed air flow in the second chamber 120. According to bernoulli's principle (p +1/2 ρ v + ρ gh ═ C, p is the pressure at a certain point in the fluid, v is the flow velocity at the point, ρ is the fluid density, g is the gravitational acceleration, h is the height at the point, and C is a constant), the pressure is smaller as the wind speed is higher, and therefore the lateral wind generated by the fourth fan 510 can cause the first chamber 110 and the third chamber 221 to generate a pressure difference, so as to accelerate the air flow in the third chamber 221 to the first chamber 110, thereby accelerating the discharge speed of the heat generated by the power supply 210 and enhancing the heat dissipation capability of the power supply module 200.

In some embodiments, the second fan module 500 further includes a fifth fan 520, the fifth ventilation opening 111 faces the horizontal direction, a seventh ventilation opening 112 is further disposed on a side wall of the second chamber 120 opposite to the fifth ventilation opening 111, and the fifth fan 520 is disposed at the seventh ventilation opening 112. Specifically, the service board 400 is located between the seventh vent 112 and the fifth vent 111, the fifth fan 520 is disposed at the seventh vent 112, and the air outlet of the fifth fan 520 faces the fifth vent 111, so that the wind generated by the fifth fan 520 can pass through the service board 400, quickly discharge the heat generated on the surface of the service board 400 out of the first chamber 110, and prevent the performance of the service board 400 from being degraded due to over-high temperature.

In some embodiments, the fourth vent 121 opens at an upper wall of the second chamber 120. Specifically, in the actual use process, the case may be placed close to the wall, so as to avoid the wall blocking the fourth air inlet 121 and influence the air discharge, in this embodiment, the fourth air inlet 121 is disposed on the upper wall of the second chamber 120, that is, the fourth air inlet 121 is disposed on the top plate 180, so that the air in the second chamber 120 is discharged upward.

Referring to fig. 2, in some embodiments, the chassis further includes a power supply duct direction changing device 600, the power supply duct direction changing device 600 is located in the second cavity 120, the power supply duct direction changing device 600 has a direction changing surface, the direction changing surface is located at the second ventilation opening 2212, and the direction changing surface and the third ventilation opening have a set angle. Specifically, the direction-changing surface has a set angle with the orientation of the second ventilation opening 2212 of the power module 200, and when the air in the power module 200 is discharged through the second ventilation opening 2212 and then touches the direction-changing surface to change the wind direction, for example, the set angle is 45 °, after the wind blown by the first fan 230 touches the direction-changing surface, the wind direction is changed from the horizontal direction to the vertical direction, so that the wind in the third chamber 221 is prevented from striking a corner (the corner at the connection between the third side plate 160 and the bottom plate 170) at the bottom of the first chamber 110, which causes a heat stagnation area, and affects the heat dissipation effect.

In addition, a plurality of fourth fans 510 can be provided in the vertical direction to accelerate the heat discharging speed. It can be understood that the plurality of fourth fans 510 arranged along the horizontal direction increases the overall volume of the chassis, and therefore, the chassis of the present embodiment can accelerate the heat dissipation and reduce the overall volume of the chassis by arranging the plurality of fourth fans 510 in the vertical direction.

Further, it is understood that in some embodiments, the service panel 400 has a first male plug (not shown), the second chamber 120 has a first sidewall having a first female plug (not shown), and the first male plug is detachably connected to the first female plug to connect the service panel 400 to the first sidewall.
