[0032] Embodiment 1

[0033] See also Figure 1 , this embodiment provides a high-voltage cabinet, which is applied to an energy storage container.

[0034] More specifically, the energy storage container is a liquid-cooled container.

[0035] Specifically, in this embodiment, the high-voltage cabinet includes a housing 1 , and a fuse 2 is disposed in the housing 1 .

[0036] Furthermore, in this embodiment, a relay 91 , an isolating switch 92 , a main controller 93 and a switching power supply 94 are also disposed in the housing 1 of the high-voltage cabinet.

[0037] The positional relationship and connection relationship of the fuse 2, relay 91, isolating switch 92, main controller 93 and switching power supply 94 belong to the prior art and will not be described in detail here.

[0038] The fuse 2 , the relay 91 and the isolating switch 92 are connected together via an electrical connection line 3 .

[0039] The high-voltage cabinet further includes an air inlet 4 , an air outlet 5 and a spoiler blowing member 6 .

[0040] The air inlet 4 is arranged at one side of the housing 1 , and a first air filter is arranged at the air inlet 4 .

[0041] The air outlet 5 is disposed on the other side of the housing 1 .

[0042] The spoiler blowing member 6 is arranged in the housing 1 , and the end side of the fuse 2 is provided with the spoiler blowing member 6 . Under the action of the spoiler blowing member 6 , the airflow flows from the air inlet 4 to the air outlet 5 .

[0043] When the high-voltage cabinet provided in this embodiment is working, the fuse 2 will generate a lot of heat; at this time, the turbulent blowing member 6 located at the end side of the fuse 2 is activated to generate flowing gas, which can drive the heat generated by the fuse 2 and form flowing hot air, and the flowing hot air flows away from the air outlet 5, and new external gas will enter the shell 1 from the air inlet 4, so that the air pressure in the shell 1 remains stable. At the same time, a first air filter is also provided at the air inlet 4 to prevent impurities in the external air, such as dust or flying catkins, from entering the shell 1.

[0044] Since the heat generated by the fuse 2 can be dissipated out of the housing 1 in time, a high temperature will not occur in the housing 1, thereby ensuring the normal operation of the main controller 93 and the switching power supply 94.

[0045] Optionally, the first air filter element is an air filter, a filter net or a filter sponge.

[0046] Optionally, the spoiler blowing member 6 is a fan.

[0047] A spoiler blowing member mounting seat is arranged in the housing 1, and the spoiler blowing member 6 is detachably arranged on the spoiler blowing member mounting seat.

[0048] The spoiler blowing member 6 can be detachably arranged on the spoiler blowing member mounting seat. Such arrangement facilitates the spoiler blowing member 6 to be inspected and replaced.

[0049] Specifically, in this embodiment, the spoiler and blowing member 6 is detachably mounted on the spoiler and blowing member mounting seat via a threaded connection member.

[0050] Furthermore, in order to ensure that the hot air flow can be stably discharged from the air outlet 5 , an air suction member 51 is provided at the air outlet 5 in the housing 1 .

[0051] Optionally, the air suction member 51 is an exhaust fan.

[0052] The spoiler blowing member 6 blows air toward the heated fuse 2, accelerating the heat dissipation of the fuse and quickly forming a hot air flow. After the exhaust fan is started, the hot air flow can be quickly extracted to prevent the hot air flow from staying in the shell 1 for a long time and affecting the heat dissipation effect of the high-voltage cabinet.

[0053] Preferably, a second air filter is provided at the air outlet 5. The provision of the second air filter will not affect the normal air outlet of the air outlet 5, and can also prevent foreign impurities from entering the housing 1 from the air outlet 5 when the spoiler blowing element 6 is not working.

[0054] Optionally, the second air filter element is an air filter, a filter net or a filter sponge.

[0055] In order to further improve the heat dissipation effect of the fuse 2 , in this embodiment, heat dissipation fins are provided on the outer side of the housing 1 at a position opposite to the fuse 2 .

[0056] Furthermore, a heat sink is provided on the outer side of the housing 1 at a position opposite to the fuse 2 , and heat sinks are provided on the heat sink.

[0057] Specifically, the heat sink is glued to the outer side of the housing 1 by means of heat-conducting adhesive.

[0058] With such arrangement, the heat generated by the fuse 2 is transferred to the heat sink via the housing 1 and the thermally conductive adhesive in sequence, and the heat is dissipated via the heat sink fins.

[0059] Optionally, the heat sink is made of metal with good thermal conductivity.

[0060] Specifically, in this embodiment, two fuses 2 are disposed in the housing 1 , and each fuse 2 is correspondingly connected to a relay 91 .

[0061] Each fuse 2 is correspondingly provided with a spoiler blowing piece 6, which is located at the end of the corresponding fuse 2 and between the fuse 2 and the corresponding relay 91. With such a configuration, the airflow formed by the spoiler blowing piece 6 can also take away the heat generated by the relay 91 during operation, further avoiding excessive temperature in the high-voltage cabinet.

[0062] Furthermore, in this embodiment, a first temperature monitoring component 7 is disposed on the inner wall of the housing 1 , and the first temperature monitoring component 7 is electrically connected to the turbulent blowing component 6 .

[0063] The fuse 2 is provided with a second temperature monitoring component 8 , and the second temperature monitoring component 8 is electrically connected to the turbulent blowing component 6 .

[0064] Specifically, when the first temperature monitoring component 7 detects that the temperature inside the shell 1 exceeds the first set temperature, and the second temperature monitoring component 8 detects that the temperature of the fuse 2 exceeds the second set temperature, the spoiler blowing component 6 and the exhaust component 51 are started at the same time, and the spoiler blowing component 6 blows air to the fuse 2 and the relay 91 and takes away the heat of the two; the gas carrying heat forms hot air, and the hot air is discharged through the air outlet 5, thereby quickly cooling the high-voltage cabinet.

[0065] When the second temperature monitoring component 8 detects that the temperature of the fuse 2 is lower than the third set temperature, the turbulent blowing component 6 and the exhaust component 51 are closed at the same time to reduce the energy consumption of the high-voltage cabinet.

[0066] Specifically, the third set temperature is lower than the first set temperature and lower than the second set temperature. The second set temperature is higher than the first set temperature.

[0067] The first set temperature, the second set temperature and the third set temperature can be set as required, and no excessive restrictions are made here.

[0068] Furthermore, in this embodiment, a first temperature monitoring component 7 is disposed on each inner side wall of the housing 1 , that is, a total of six first temperature monitoring components 7 are disposed in the housing 1 .

[0069] Two fuses 2 are arranged in the housing 1 , and each fuse 2 is provided with a second temperature monitoring component 8 .

[0070] Exemplarily, when the high-voltage cabinet is working, when any first temperature monitoring component 7 detects that the temperature inside the shell 1 exceeds the first set temperature, and any second temperature monitoring component 8 detects that the temperature of the fuse 2 corresponding to the second temperature monitoring component 8 exceeds the second set temperature, the exhaust component 51 and the turbulent blowing component 6 corresponding to the second temperature monitoring component 8 are started at the same time.

[0071] After the air extraction member 51 and the spoiler blowing member 6 are started at the same time, the airflow with a lower temperature from the outside enters the housing 1 from the air inlet 4. Under the action of the spoiler blowing member 6, a flowing airflow is formed inside the housing 1 and the flowing airflow can accelerate the heat dissipation of the fuse 2. The flowing airflow takes away the heat of the fuse 2 and flows out through the air outlet 5, preventing the hot airflow from staying in the housing 1. In this process, the first air filter filters the air entering the housing 1.

[0072] At the same time, part of the heat of the fuse 2 is transferred to the heat sink via the thermal conductive adhesive, and the heat dissipation fins on the heat sink can quickly conduct the transferred heat, further improving the heat dissipation effect of the fuse 2.

[0073] When the second temperature monitoring element 8 detects that the temperature of the fuse 2 is lower than the third set temperature, the spoiler blowing element 6 and the air extraction element 51 are closed simultaneously. At this time, the first air filter element and the second air filter element can prevent impurities in the outside air from entering the housing 1.

[0074] Embodiment 2

[0076] Optionally, the energy storage container provided in this embodiment is an energy storage container with a liquid cooling system.

[0077] When the high-voltage cabinet of the energy storage container is working, the fuse 2 will generate a lot of heat; at this time, the turbulent blowing member 6 located at the end side of the fuse 2 is activated to generate flowing gas, which can drive the heat generated by the fuse 2 and form flowing hot air, which flows away from the air outlet 5, and new external gas will enter the shell 1 from the air inlet 4, so that the air pressure in the shell 1 remains stable. At the same time, a first air filter is also provided at the air inlet 4 to prevent impurities in the external air, such as dust or flying catkins, from entering the shell 1.
