< mode of operation: compressor Cooling mode >

Fig. 15 is an airflow schematic of a cabinet in a cooling mode according to an embodiment of the present application.

Referring to fig. 15, when the temperature outside the cabinet is higher than a certain set value, specifically, the temperature outside the base station is higher than a certain set value, the cabinet is in the press cooling mode: outdoor fan 313, compressor 311 start, and new trend mechanism 230 closes (not with the outer UNICOM of rack), and fan module 210 continues the operation, and the rack is closed state this moment, and the rack lower part is from formula aerofoil 236 self-closing under the action of gravity.

The refrigeration module 220 provides cool air to the cool airflow path 910. The cool air flows in the cool airflow passage 910, the ventilation gap between the adjacent two apparatuses 800, and the inside of the apparatus 800 to reduce the temperature of the apparatus 800 by exchanging heat with the apparatus 800. The gas after heat exchange by the apparatus 800 flows to the hot airflow channel 920, then flows to the fan inlet 211a of the fan module 210 together with the hot airflow in the hot airflow channel 920, and then flows to the cooling outlet 221b of the cooling module 220 through the fan module 210, thereby completing a gas circulation.

< mode of operation: fluorine Pump Cooling mode >

The fluorine pump 312 is mainly used for energy conservation, when the outside temperature of the base station is lower than a certain set value, the fluorine pump 312 is started, the compressor 311 stops running, the fan module 210 is started, and the fluorine pump 312 system is used for refrigerating so as to fully utilize an outdoor cold source and achieve an energy-saving effect.

The air flow circulation in the cabinet is the same as that in the compressor refrigeration mode when the cabinet is in the fluorine pump refrigeration mode, and the description is omitted.

Referring to fig. 16, when the temperature sensor detects that the outside temperature is lower than the set value or the inside return air temperature reaches the emergency temperature, the compressor 311 and the outdoor fan 313 are stopped, the fresh air mechanism 230 is opened (communicated with the outside of the cabinet), the fan module 210 continuously operates to blow the inside return air inside the cabinet to the outside of the cabinet, negative pressure is maintained inside the cabinet, so that the self-hanging type air plate 236 at the lower part of the cabinet is automatically opened, outside cold air outside the cabinet is sucked from the air inlet, enters from the front or the left side of the equipment through the cabinet cold air flow channel 910 to take away the heat of the equipment, and high-temperature return air enters the cabinet hot air flow channel 920 from the back and the right side, is sucked by the fan module 210 in the hot air flow channel 920, and is sent to the outside of the cabinet after pressurization.

The cabinet is refrigerated by fully utilizing external natural cold air, so that the energy-saving performance of the cabinet can be improved.

< mode of operation: emergency Ventilation mode >

When the refrigeration device fails, for example, the compressor 311 or the fluorine pump 312 fails, the outdoor fan 313 is stopped synchronously, or the utility power is cut off, the fan module 210 continuously operates to start the fresh air mechanism 230, and the gas circulation in the cabinet in this mode is the same as the gas circulation in the refrigeration mode using the external natural cold air, which is not described again.

The cabinet can still be ensured to radiate heat for the equipment under the condition that the refrigeration unit fails or the commercial power is cut off by utilizing the emergency ventilation mode, and the reliability of the equipment is improved.

< mode of operation: waste heat utilization mode >

When the temperature in the cabinet is lower than a certain set value, the refrigeration module 220 is closed, the fresh air mechanism 230 is closed, the fan module 210 is opened, and the fan module 210 blows hot air generated by the equipment to a battery (not shown) arranged in the installation space 110a, so that the battery activity is prevented from being influenced by the fact that the battery is in a low-temperature environment for a long time.

The battery is the stand-by power supply of rack to guarantee still can utilize stand-by battery to provide the power for relevant consumer under the outage circumstances, guarantee the normal operating of rack.

The cabinet of this application has five kinds of mode, is normal press refrigeration mode, fluorine pump refrigeration mode, nature cold source mode, emergent ventilation mode and the interior waste heat utilization mode of cabinet respectively, through the change of the temperature of monitoring the inside and outside and outer environment of basic station of cabinet and the operational aspect of relevant equipment, suitable refrigeration mode can be selected for use in a flexible way to the cabinet to realize energy-efficient, improve equipment's cooling efficiency guarantees that the cabinet can long-term reliable operation.

In some embodiments of this application, the cabinet door of rack is automatic spring open door, and when refrigerating unit broke down or commercial power outage, the rack got into emergent ventilation mode earlier, if the interior temperature of cabinet lasts the rising and reaches the setting value, then the cabinet door can be automatic spring open, can reduce the equipment risk of dying.

According to the application, the indoor unit of the refrigerating device is integrated on the cabinet, cold air is directly provided for the cabinet through the refrigerating device, the cold quantity is fully utilized, and the refrigerating and heat-dissipating efficiency in the cabinet is improved.

According to the application, the fan module is arranged in the cabinet body and the refrigeration module is arranged on the cabinet door, so that the space in the cabinet can be saved, the fan module and the refrigeration module are butted to realize refrigeration and heat dissipation in the cabinet when the cabinet door is closed, and the utilization efficiency of cold energy and the heat dissipation efficiency in the cabinet are improved.
