Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is described in detail with reference to the accompanying drawings.

As shown in Fig. 4 to Fig. 10, it is the first embodiment of the direct ventilation heat dissipation cabinet of the present invention. The direct ventilation heat dissipation cabinet of this embodiment includes a cabinet body 100, wherein the upper part of the cabinet body 100 is an equipment compartment for placing For electronic equipment, such as power devices, switches, server parts and other equipment, the lower part is the battery compartment, which is used to place the battery pack. Since the heat generated by the battery pack is relatively small, there is no need to install a heat sink. The heat dissipation requirements of the cabinet are mainly concentrated in the equipment compartment. The front door panel 110 of the cabinet is provided with an air inlet 111, the left side panel 120 of the cabinet is provided with an air outlet 121, and the right side panel 130 is provided with an air outlet 131, and the air inlet 111 and the air outlets 121, 131 are arranged facing the equipment compartment. . An equipment mounting frame 140 is provided in the equipment compartment, and the pen-related mounting frame includes opposite first side plates 141 and second side plates 142, and a top plate 143, the first side plate 141 is parallel to the left side plate, and the first side plate 141 A frame body is arranged between the second side plate 142 and the second side plate 142 . The air inlet 111 faces the equipment mounting frame 140, and the main cooling channel 150 is formed between the first side plate 141 and the second side plate 142. The device cools down. An air guide cavity 160 is arranged above the equipment mounting frame 140 for changing the direction of the cooling air flow in the equipment compartment. The air guide cavity 160 has a first opening 161 facing the back plate 170 and facing the left side 120 respectively. And the second opening 162 and the third opening 163 of the right side plate 130, the second opening 162 is equipped with a fan 164, and the third opening 163 is equipped with a fan 165. A first branch heat dissipation channel 151 is formed between the first side plate 141 and the left side plate 120 of the equipment mounting frame 140, and a second branch heat dissipation channel 152 is formed between the second side plate 142 and the right side plate 130. The first branch heat dissipation channel 151 and the second branch heat dissipation channel 152 are relative to the main heat dissipation channel 150 , which divide the airflow of the main heat dissipation channel 150 into two.

The arrows in FIGS. 7 to 10 indicate the flow direction of the cooling air flow. When the cabinet is in operation, the fans 164 and 165 are started, and the gas inside the equipment compartment is discharged from the second opening 162 and the third opening 163 respectively and passes through the first branch respectively. The heat dissipation channel 151 and the second branch heat dissipation channel 152 are discharged from the exhaust ports 121 and 131. Since the gas in the equipment compartment is sucked away, a negative pressure is formed at the air inlet 111 to suck in external air, and the external air flows after being sucked in. The heat generated by the device is taken away through the main cooling channel 150 .

The fans 164, 165 in this example may be axial fans or centrifugal fans. In order to prevent external air from bringing dust into the cabinet, a filter screen may be provided at the air inlet 111 .

In this embodiment, both the air inlet 111 and the air outlets 121 and 131 adopt a hole array structure, and a grid structure may also be used in practice. In this embodiment, the air outlets 121 and 131 are arranged symmetrically, but in practice, an asymmetrical structure may also be adopted as required.

As shown in Figure 11 to Figure 17, it is the second embodiment of the direct ventilation heat dissipation cabinet of the present invention. The difference between this embodiment and the first embodiment is that in this embodiment, the battery compartment is removed from the cabinet body part, the structure of other parts is the same as that of the first embodiment, and will not be repeated here.

In the direct ventilation heat dissipation cabinet of the present utility model, air outlets are provided on the left side panel and the right side panel of the cabinet body, which fully utilizes the space on both sides of the cabinet, and the side of the cabinet has a larger area, so a larger area can be set. The air outlet improves the space utilization and heat dissipation efficiency of the cabinet.

The direct ventilation cooling cabinet of the utility model can be used as an uninterruptible power supply cabinet, a communication cabinet, or a server cabinet.
