[0020] Example 1

[0021] Reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, provides a switch cabinet with a heat reflux device. The switch cabinet with a heat reflux device includes a main body component 100 and a heat dissipation component 200. The two can prevent hot air from passing through the hollow part and entering the electrical components again.

[0022] The main assembly 100 includes a switch cabinet 101 , a door body 102 and a control board 103 . The door body 102 is disposed on one side of the switch cabinet 101 , and the control board 103 is fixed to one side of the door body 102 .

[0023] The switch cabinet 101 is a device for installing, protecting and connecting electrical equipment.

[0026] Example 2

[0027] Reference Figure 1 to Figure 3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0028] Specifically, the heat sink 201 includes a heat dissipation fan 201a and a protective frame 201b. The heat dissipation fan 201a is arranged on one side of the door body 102, and the protective frame 201b is sleeved on the outside of the heat dissipation fan 201a. The protective frame 201b and the heat dissipation fan 201a are movably connected.

[0029] The rotation of the cooling fan 201a can generate wind force, thereby dissipating heat inside the switch cabinet. The rotation of the cooling fan 201a belongs to the existing technology, so it will not be elaborated in detail. The protective frame 201b is used to support the cooling fan 201a to prevent the cooling fan 201a from deflecting.

[0030] Specifically, the heat sink 201 further includes a fixing plate 201c and a first bolt 201d. The fixing plate 201c is fixed to one side of the protection frame 201b. The first bolt 201d is plugged into one side of the fixing plate 201c. The first bolt 201d and the fixing plate 201c are threadedly connected.

[0031] The fixing plate 201c is rotatably connected to one side of the cooling fan 201a via a bearing, and the fixing plate 201c is fixed to one side of the door body 102. The setting of the fixing plate 201c can support the protective frame 201b to prevent the protective frame 201b from shifting. The first bolt 201d is inserted into one side of the door body 102, and the first bolt 201d is threadedly connected to the door body 102. The setting of the first bolt 201d can fix the fixing plate 201c to one side of the door body 102 to prevent the fixing plate 201c from falling off.

[0032] Specifically, the closing member 202 includes a closing plate 202a and a sealing ring 202b. The closing plate 202a is located in the switch cabinet 101, and the sealing ring 202b is sleeved on the outer side of the closing plate 202a.

[0033] The hollow space on one side of the switch cabinet can be sealed by setting the closing plate 202a, thereby preventing hot air from entering the electrical components. The sealing ring 202b can ensure the sealing of the closing plate 202a and prevent wind from leaking from one side of the closing plate 202a.

[0034] Specifically, the closing member 202 further includes a clamping plate 202c and a second bolt 202d. The clamping plate 202c is disposed on one side of the closing plate 202a. The second bolt 202d is inserted into one side of the clamping plate 202c. The second bolt 202d is threadedly connected to the clamping plate 202c.

[0035] When it is necessary to fix the closing plate 202a in the switch cabinet 101, first place the closing plate 202a and the sealing ring 202b at the designated position in the switch cabinet 101, and then put the clamping plate 202c on the outside of the closing plate 202a. At this time, turn the second bolt 202d, and the second bolt 202d is inserted into the inner wall of the switch cabinet 101. The second bolt 202d is threadedly connected to the switch cabinet 101. By turning the second bolt 202d, the clamping plate 202c can be fixed to the inner wall of the switch cabinet 101, thereby completing the installation of the closing plate 202a.

[0036] During use, when the switch cabinet 101 needs to dissipate heat, the closing plate 202a needs to be installed in the switch cabinet 101 first. First, the closing plate 202a and the sealing ring 202b are placed at the designated positions in the switch cabinet 101, and then the clamping plate 202c is put on the outside of the closing plate 202a. At this time, the second bolt 202d is rotated. By rotating the second bolt 202d, the clamping plate 202c can be fixed to the inner wall of the switch cabinet 101, thereby completing the installation of the closing plate 202a.

[0037] When it is necessary to dissipate heat for the electrical components in the switch cabinet 101, the cooling fan 201a is started. When the cooling fan 201a rotates, wind will be generated, and the heat in the electrical components will be blown away. At this time, the heat will be blown to the side of the closing plate 202a. The setting of the closing plate 202a and the sealing ring 202b can block the hot air and prevent the hot air from entering the electrical components from the rear end. At this time, the hot air will be discharged from the exhaust duct on one side of the switch cabinet 101.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
