Detailed ways

As shown in Figure 2, the utility model comprises a first chamber 11 and a second chamber 12 separated by a partition 16, both of which are used to place electronic components, and the first chamber 11 and the second chamber One of the chambers 12 is provided with an air inlet 14 , and the other is provided with an air outlet 17 and a fan 13 , and a plurality of through holes 15 are opened on the partition 16 .

By opening a number of through holes 15 on the partition plate 16, a number of air passages passing through the first chamber 11 and the second chamber 12 are formed, and at the same time, the first chamber 11 and the second chamber 12 are dissipated, and the heat dissipation effect is good , The structure is simple, and only one air outlet 17 and fan 13 need to be set, which reduces the cost. The size of the through hole 15 can be adjusted up or down according to heat dissipation requirements, which is convenient for different occasions.

Further, the first chamber 11 is used to place the main heat generating device, and the second chamber 12 is used to place the secondary heat generating device. The air inlet 14 is located at the lower left corner of the first chamber 11 . The air outlet 17 is located at the upper right corner of the second chamber 12 .

The airflow first enters the first chamber 11 from the air inlet 14, flows along the device gap under the action of the fan 13, passes through the through hole 15 opened on the partition 16, and then enters the second chamber 12, and is discharged out of the cabinet. in vitro. The whole air duct forms the way that the lower part of one chamber enters the air, and the upper part of the other chamber discharges the air. Since the air flow first enters the first chamber 11 , the heat dissipation effect of the first chamber 11 is better than that of the second chamber 12 , so the main heat-generating components are placed in the first chamber 11 . Setting the air inlet 14 at the lower left corner can increase the radiation range of the air duct.

Further, the through hole 15 is arranged near the key heat-generating point of the main heat-generating device.

When the airflow reaches the area near the through hole 15 of the partition 16, the cross section of the flow channel becomes smaller and the airflow is accelerated. At this time, the surface near the key point of the heat generating device passes over the airflow at a higher speed, so that the heat is quickly taken away to realize cooling. .

Further, the components in the first chamber 11 are mounted on the partition 16 , and most of the components in the second chamber 12 are mounted on the partition 16 .

When the air flow quickly passes through the surface of the through hole 15, the partition 16 is also cooled, so the devices placed on the partition 16 can also be cooled to a certain extent.

Further, the fan 13 is arranged on the air outlet 17, and the fan 13 is an exhaust fan.

Such a setting can speed up the flow speed of the airflow, so that the airflow can be discharged from the air outlet 17 as soon as possible, thereby further enhancing the heat dissipation effect.

Further, a second fan is provided inside the second chamber 12, and the second fan is a blower. The setting of the second fan is to speed up the flow velocity of the airflow in the second chamber 12, so that it can be quickly discharged from the air outlet 17, thereby further enhancing the heat dissipation effect.

The utility model provides a through hole 15 near the key heating point of the main heating device, uses the strong air flow formed by the opening to carry out centralized cooling, adopts the air extraction method, and discharges the heat outside the cabinet in the form of an air duct from bottom to top. The structure of the whole air duct is compact, which realizes the miniaturization of the device while realizing the cooling of the components in the cabinet.
