[0028] (3) In order to cope with the case that the temperature in the cabinet is relatively high, the intelligent sealed heat exchange cabinet of the application sets the negative pressure air inlet assembly at the lower part of the cabinet, when the cabinet needs to be cooled, the air entering the negative pressure air inlet assembly will go upwards due to the traction of the intelligent exhaust assembly, because the temperature of the air outside is lower than that of the air in the cabinet, the lower-temperature air will take away the heat of the electronic components, and then be exhausted to the outside from the intelligent exhaust assembly, so as to complete the cooling of the electronic components in the cabinet.

DETAILED DESCRIPTION

[0040] The present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] Reference Figures 1 to 5 As shown in the figure, the intelligent sealed heat exchange cabinet provided by the embodiment of the present application comprises a cabinet 1, an intelligent controller 2, a heat exchange assembly 3, an intelligent exhaust assembly 4, an argon bottle 5 and a negative pressure air inlet assembly 6. The intelligent controller 2 is installed in the cabinet 1; the heat exchange assembly 3 is installed at the top of the cabinet 1, and the heat exchange assembly 3 is electrically connected with the intelligent controller 2; the intelligent exhaust assembly 4 is installed at the top of the cabinet 1, and the intelligent exhaust assembly 4 is electrically connected with the intelligent controller 2; the argon bottle 5 is installed at the top of the cabinet 1, and the argon bottle 5 is provided with an argon control valve, and the argon control valve is electrically connected with the intelligent controller 2; the negative pressure air inlet assembly 6 is installed at the bottom of the cabinet 1, and the negative pressure air inlet assembly 6 is electrically connected with the intelligent controller 2.

[0042] It should be noted that the argon bottle 5 is also provided with an argon pressure sensor, and the argon pressure sensor is electrically connected with the intelligent controller 2. The argon pressure sensor can monitor the amount of argon in the argon bottle 5. When the argon is used up, the argon pressure sensor will send a signal to the intelligent controller 2. After the intelligent controller 2 receives the signal, it sends information to the client through the 4G antenna electrically connected with the intelligent controller, so as to remind the inspection personnel to supplement the argon in time.

[0043] In addition, the intelligent controller 2, the heat exchange assembly 3, the intelligent exhaust assembly 4 and the argon cylinder 5 are provided with screw holes, and screws 7 are used to fix the intelligent controller 2, the heat exchange assembly 3, the intelligent exhaust assembly 4 and the argon cylinder 5 on the top of the cabinet.

[0044] Since the hot air in the cabinet 1 will accumulate in the top space of the cabinet 1 due to its specific gravity, the intelligent sealed heat exchange cabinet of the present application installs the heat exchange assembly 3 on the top of the cabinet 1, and controls the heat exchange assembly 3 through the intelligent controller 2, so that the heat exchange assembly 3 exchanges heat with the hot air, thereby reducing the temperature inside the cabinet 1.

[0045] Since the argon is 1.4 times the specific gravity of air, the argon will accumulate in the bottom of the cabinet 1, therefore, the intelligent sealed heat exchange cabinet of the present application installs the argon cylinder 5 on the top of the cabinet 1, when the argon cylinder 5 releases argon, the argon will sink to the bottom of the cabinet 1, thereby pushing the air in the cabinet 1 upwards, at the same time, the released argon is low-temperature argon, which can cool down, and since the cabinet 1 is sealed, releasing argon into the cabinet 1 will cause the air pressure inside the cabinet 1 to rise, in order to protect the electronic components inside the cabinet 1, the amount of argon released by the argon cylinder 5 into the cabinet 1 will be limited, therefore, by installing the intelligent exhaust assembly on the top of the cabinet 1, the air pushed to the top of the cabinet 1 can be exhausted, thereby ensuring the air pressure balance inside the cabinet 1, and since the intelligent exhaust assembly is installed on the top of the cabinet 1, the intelligent exhaust assembly can preferentially exhaust hot air, thereby further improving the cooling effect. In addition, by filling the argon in the cabinet 1, the connection terminals of the wires between the devices and the electrical element contacts can be isolated from oxygen.

[0046] Preferably, the heat exchange assembly 3 comprises, in sequence, a heat dissipation fin 31, a semiconductor refrigeration fin 32 and a heat absorption fin 33, the heat absorption fin 33 faces the inside of the cabinet 1, and the heat dissipation fin 31 faces the outside of the cabinet 1.

[0047] In principle, semiconductor refrigeration sheet 32 is a heat transfer tool. When there is current through the thermocouple pair of a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends, and heat will be transferred from one end to the other, thereby forming a cold and hot end. The cold end is connected to the heat absorption sheet 33, so that the heat absorption sheet 33 can absorb the heat of the hot air, and the hot end is connected to the heat dissipation sheet 31, so that the heat dissipation sheet 31 can dissipate the heat of the hot end to the outside, so that the hot air in the cabinet 1 completes heat exchange through the heat exchange assembly 3, thereby reducing the temperature inside the cabinet 1. It should be noted that the heat dissipation sheet 31 can be composed of a plurality of heat dissipation fins arranged in a row, and gaps exist between the heat dissipation fins. The heat dissipation fins can be made of materials with good thermal conductivity such as aluminum alloy, brass or bronze. The heat absorption sheet 33 can be composed of a plurality of heat absorption fins arranged on a whole sheet. The sheet and the heat absorption fins can be made of materials with good thermal conductivity such as aluminum alloy, brass or bronze. It should be noted that the heat dissipation sheet 31 is provided with a screw hole, and the screw 7 is fixed to the top of the cabinet body 11 through the screw hole.

[0048] Preferably, the intelligent exhaust assembly 4 includes an exhaust valve and an exhaust fan, the cabinet 1 is provided with an exhaust port, the exhaust fan is installed in the exhaust port, and the exhaust valve is used to seal or open the exhaust port. The exhaust valve and the exhaust fan are electrically connected to the intelligent controller 2, and the intelligent controller 2 controls the opening and closing of the exhaust valve and the start and stop of the exhaust fan.

[0049] Because the intelligent sealed heat exchange cabinet is used in places such as reservoir flood discharge station, rainwater drainage station, agricultural drinking valve station, tide gate, ecological sluice, etc. The air in these places is humid, and it is easy to form condensation on the surface of metal, causing the connection terminals of wires between devices, electrical element contacts, etc. to oxidize and cause poor contact or even corrosion. Therefore, the exhaust valve is provided, and under normal conditions of the temperature inside the cabinet 1, the exhaust valve seals the exhaust port, thereby preventing the air outside the cabinet 1 from entering the inside of the cabinet 1 through the exhaust port, preventing the electronic elements from being corroded. At the same time, when the temperature inside the cabinet 1 is abnormal, the intelligent controller 2 controls the exhaust valve to open, so that the exhaust port is open to the outside of the cabinet 1, and then the exhaust fan is used to exhaust the hot air inside the cabinet 1, thereby completing the cooling of the inside of the cabinet 1. The intelligent controller 2 controls the exhaust valve by energizing the inlet opening and closing motor and controlling the inlet opening and closing motor to work, thereby controlling the exhaust valve. The intelligent controller 2 controls the exhaust fan by energizing the inlet fan motor and controlling the inlet fan motor to work, thereby controlling the exhaust fan.

[0050] Preferably, the negative pressure air inlet assembly 6 includes an air inlet valve and an air inlet fan, the cabinet 1 is provided with an air inlet, the air inlet fan is installed in the air inlet, and the air inlet valve is used to seal or open the air inlet. The air inlet valve and the air inlet fan are electrically connected to the intelligent controller 2, and the intelligent controller 2 controls the opening and closing of the air inlet valve and the start and stop of the air inlet fan.

[0051] In order to be able to cope with the case that the temperature inside the cabinet 1 is high, the intelligent sealing heat exchange cabinet of the present application sets the negative pressure air inlet assembly 6 at the lower part of the cabinet 1. When the cabinet 1 needs to be cooled, through the cooperation of the negative pressure air inlet assembly 6 and the intelligent air exhaust assembly 4, the air entering the negative pressure air inlet assembly 6 will go upwards due to the traction of the intelligent air exhaust assembly 4. Since the temperature of the air outside is lower than that of the air inside the cabinet 1, the air with lower temperature will take away the heat of the electronic components, and then be exhausted to the outside from the intelligent air exhaust assembly 4, thereby completing the cooling of the electronic components inside the cabinet 1. The intelligent controller 2 controls the air inlet valve by energizing the air vent opening and closing motor and controlling the operation of the air vent opening and closing motor. The intelligent controller 2 controls the air inlet fan by energizing the air vent fan motor and controlling the operation of the air vent fan motor. The negative pressure air inlet assembly 6 is provided with a screw hole, and the screw 7 is fixed in the screw hole.

[0052] Preferably, the power of the air inlet fan of the negative pressure air inlet assembly 6 is the same as the power of the air exhaust fan of the intelligent air exhaust assembly 4. By setting the power of the air inlet fan to be the same as the power of the air exhaust fan, the air inlet amount of the air inlet fan and the air exhaust amount of the air exhaust fan can be kept consistent, thereby ensuring the balance of the air pressure inside the cabinet 1 and the outside, and at the same time completing the exchange of the cold air outside and the hot air inside the cabinet 1, and realizing the cooling of the inside of the cabinet 1.

[0053] Preferably, the cabinet 1 comprises a cabinet body 11 and a cabinet door 12, the cabinet body 11 and the cabinet door 12 are rotationally connected, and the negative pressure air inlet assembly 6 is arranged at the lower part of the cabinet door 12. The cabinet body 11 and the cabinet door 12 form a sealed cavity capable of accommodating electronic components. By opening the cabinet door 12, the inspection personnel can observe the running state of the equipment placed in the cabinet body 11, thereby performing inspection. At the same time, the air inlet is arranged at the lower part of the cabinet door 12, and the negative pressure air inlet assembly 6 is installed in the air inlet, so that the cold air outside can fill from the lower part of the cabinet 1, and then press the hot air inside the cabinet 1 upwards and exhaust it through the intelligent air exhaust assembly 4. It should be noted that the cabinet 1 further comprises a cabinet door detection switch, the cabinet door detection switch is electrically connected with the intelligent controller, one end of the cabinet door detection switch is arranged on the cabinet body 11, and the other end is arranged on the cabinet door 12. When the cabinet door 12 and the cabinet body 11 are closed, the cabinet door detection switch can monitor the closing of the cabinet door 12, thereby feeding back to the intelligent controller 2.

[0054] Preferably, the heat exchange assembly 3 further comprises a temperature sensor, and the intelligent exhaust assembly 4 further comprises an argon sensor, the temperature sensor and the argon sensor being electrically connected to the intelligent controller 2, the temperature sensor being configured to detect the temperature inside the cabinet 1, and the argon sensor being configured to detect the argon concentration at the position of the intelligent exhaust assembly 4. The intelligent controller 2 sends instructions according to the temperature detected by the temperature sensor, and when the temperature inside the cabinet 1 detected by the temperature sensor is higher than a certain value, the intelligent controller 2 controls one or more of the heat exchange assembly 3, the intelligent exhaust assembly 4, the argon cylinder 5 and the negative pressure air inlet assembly 6 to work, so as to reduce the temperature inside the cabinet 1 to a normal value. Meanwhile, the intelligent controller 2 sends instructions to the argon cylinder 5 according to the argon concentration detected by the argon sensor, controls the argon release amount of the argon cylinder 5, and ensures that the argon can fill the inside of the cabinet 1, so as to isolate the equipment in the cabinet 1 from the air and avoid waste of argon.

[0055] Referring to Figure 6 The embodiment of the present application also provides a control method of the intelligent sealed heat exchange cabinet, which comprises the following steps:

[0056] Step 1, referring to Figure 7 The intelligent controller 2 detects whether the temperature inside the cabinet 1 reaches a first threshold value, if not, the process is ended, and if yes, the intelligent controller 2 powers on the heat exchange assembly 3 to control the heat exchange assembly 3 to exchange heat, and simultaneously sends warning information to the client;

[0057] Step 2, referring to Figure 8 The intelligent controller 2 further detects the temperature inside the cabinet 1, if the temperature drops to a second threshold value after the heat exchange assembly 3 works in step 1, the intelligent controller 2 stops powering on the heat exchange assembly 3, and the heat exchange assembly 3 stops working, if the temperature continues to rise to a third threshold value, the intelligent controller 2 includes the following operations: (1) controls the heat exchange assembly 3 to continue working; (2) controls the argon control valve of the argon cylinder 5 to open, and the argon cylinder 5 releases low-temperature argon; (3) controls the exhaust valve of the intelligent exhaust assembly 4 to open and the exhaust fan to start working; (4) sends warning information to the client;

[0058] Step 3, referring to Figure 9As shown, the intelligent controller 2 further detects the temperature inside the cabinet 1. After the argon cylinder 5 and the intelligent exhaust assembly 4 work through step 2, if the temperature drops to the second threshold value, the intelligent controller 2 controls the argon control valve of the argon cylinder 5 to close, and controls the exhaust valve of the intelligent exhaust assembly 4 to close and the exhaust fan to stop working. If the temperature continues to rise to the fourth threshold value, the intelligent controller 2 includes the following operations: (1) controlling the argon control valve of the argon cylinder 5 to close; (2) controlling the heat exchange assembly 3 to continue working; (3) controlling the intake valve of the negative pressure intake assembly 6 to open and the intake fan to start working; (4) further detecting the temperature inside the cabinet 1 until the temperature inside the cabinet 1 drops to the second threshold value, and controlling the intelligent exhaust assembly 4, the heat exchange assembly 3 and the negative pressure intake assembly 6 to stop working; (5) sending warning information to the client.

[0059] Preferably, the first threshold value is 50℃, the second threshold value is 45℃, the third threshold value is 60℃, and the fourth threshold value is 65℃.

[0060] In this embodiment, the first threshold value is set to 50℃, because at 50℃, the heat can be exchanged to the outside through the heat exchange assembly 3. When the temperature drops to 45℃, it belongs to the normal temperature range of the equipment in the cabinet 1. When the temperature rises to 60℃, it is difficult to quickly reduce the temperature only by the heat exchange assembly 3. Therefore, in order to curb the further rise of the temperature inside the cabinet 1, the third threshold value is set to 60℃, and the temperature inside the cabinet 1 can be quickly reduced to the second threshold value by opening the argon cylinder 5 and the intelligent exhaust assembly 4. When the temperature further rises to 65℃, in order to quickly reduce the temperature, the fourth threshold value is set to 65℃, and the temperature can be quickly reduced to the second threshold value by working of the intelligent exhaust assembly 4 and the negative pressure intake assembly 6.

[0061] Preferably, the control method further includes step 4, and the intelligent controller 2 of step 4 performs the following operations: (1) controlling the argon control valve of the argon cylinder 5 to open, and the argon cylinder 5 releases low-temperature argon; (2) controlling the exhaust valve of the intelligent exhaust assembly 4 to open and the exhaust fan to start working; (3) detecting the argon concentration at the position of the exhaust valve, and when the argon concentration at the position of the exhaust valve reaches a certain concentration, controlling the argon control valve of the argon cylinder 5 to close, and controlling the exhaust valve of the exhaust assembly to close and the exhaust fan to stop working.

[0062] After the cooling inside the cabinet 1 is completed, the cabinet 1 is filled with air from the outside, so the argon released by the argon cylinder 5 fills the cabinet 1 by controlling the intelligent terminal to control the argon cylinder 5 and the intelligent exhaust assembly 4 to exhaust the air inside the cabinet 1. Since argon is an inert gas, it can protect the equipment in the cabinet 1 from oxidation, prolong the service life of the equipment and reduce the failure rate of the equipment.

[0063] The above merely describes preferred embodiments of the present application, and is not intended to limit the technical scope of the present application in any way. Any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application shall still fall within the technical scope of the present application.
