[0036] How it works

[0037] 1) Sealing and exhaust control:

[0038] The sealing plate 201 is slidably connected to the crossbeam 101 of the box body 1 through the first sliding groove 102 and can move up and down; when the temperature inside the box body 1 is normal, the sealing plate 201 is driven by the threaded rod 401 and the first sliding block 402 in the moving assembly to cover the exhaust window 103 to prevent external debris from entering the box body 1; when the temperature inside the box body 1 rises, the temperature measuring element detects a high temperature signal, and the control unit 701 drives the motor 501 to rotate the threaded rod 401 to move the sealing plate 201 away from the exhaust window 103 to allow exhaust.

[0039] 2) Cooling and heat dissipation:

[0040] The cooling fan 301 is located on the outside of the sealing plate 201, and is slidably connected to the second fixed frame 302 through the second sliding groove, and can also move up and down; when cooling is required, the cooling fan 301 is driven by the moving component threaded rod 401 and the second sliding block 403, and moves to the exhaust window 103 position to exhaust and dissipate heat from the inside of the box 1, thereby helping to reduce the temperature inside the box 1; when the cooling fan 301 is not working, it can be retracted into the dustproof plate 105 to protect the cooling fan 301 and extend its life.

[0041] 3) Temperature monitoring and automatic control:

[0042] The temperature probe 702 in the temperature measuring element extends into the interior of the box 1 to monitor the temperature in real time; at the same time, the high temperature signal of the temperature probe 702 is received by the control unit 701 to automatically control the driving motors 501 on both sides, and then control the movement of the sealing plate 201 and the cooling fan 301, thereby realizing automatic temperature control and explosion-proof protection.

[0043] The electric heating cable temperature control box in the utility model realizes effective control and explosion-proof protection of the temperature in the box body 1 through the coordinated work of the sealing element and the cooling element, combined with temperature monitoring and automatic control. When the temperature in the box body 1 rises, the system will automatically open the exhaust window 103 and start the cooling fan 301 to dissipate heat to prevent the occurrence of explosion accidents.
