Since the cooling pipe is in a curved structure inside the temperature control box, it can absorb heat evenly. The fan 1 at the bottom of the temperature control box blows air to circulate the gas inside the temperature control box to assist in cooling. The electronic fluorine liquid after absorbing heat is transferred to the cooling box for cooling.

DETAILED DESCRIPTION
[0019] The following is combined with Figure 1-3 This application is described in further detail.
[0020] The present application embodiment discloses an overheat protection device for an intelligent temperature control box. Figure 1-3, an overheating protection device for an intelligent temperature control box, comprising a temperature control box 1, a circuit board 2 is arranged inside the temperature control box 1, a rheostat 3 and a relay 4 are arranged on one side of the circuit board 2, a thermocouple 17 is arranged on one side of the temperature control box 1, a fan 5 is arranged at the bottom end of the temperature control box 1, an electronic fluoride liquid storage box 6 is arranged on one side of the temperature control box 1, a water pump 7 is arranged inside the electronic fluoride liquid storage box 6, a cooling pipe 8 is connected to the output end of the water pump 7, the other end of the cooling pipe 8 passes through the temperature control box 1 and is connected to a cooling box 9, a water pump 10 is arranged inside the cooling box 9, a water pump 10 is connected to the output end of the water pump 10, a water pipe 11 is connected, and the other end of the water pipe 11 is fixedly connected to the electronic fluoride liquid storage box 6;
[0021] Reference Figure 3 , the cooling pipe 8 is located in the inner area of the temperature control box 1 and has a curved structure;
[0022] By adopting the above technical solution, the curved structure is evenly distributed, so that the electronic fluorinated liquid inside the cooling pipe 8 can absorb heat evenly.
[0023] Reference Figure 1 , a manual switch 15 and a display screen 16 are provided on one side of the temperature control box 1;
[0024] By adopting the above technical solution, the display screen 16 can display the external and internal temperatures in real time, and the manual switch 15 can manually shut down the intelligent thermostat.
[0025] Reference Figure 1 , a seismic isolation pad 18 is provided at the bottom of the temperature control box 1, and the temperature control box 1 is made of stainless steel and carbon fiber composite material;
[0026] By adopting the above technical solution, the seismic isolation pad 18 can prevent the thermostat 1 from being vibrated by external forces and causing the internal device to be triggered incorrectly, and the stainless steel and carbon fiber composite materials can be heat-resistant and prevent magnetic interference.
[0027] Reference Figure 2 , the internal circuits of the temperature control box 1 are all provided with filters 19;
[0028] By adopting the above technical solution, the filter 19 can reduce the false triggering of overheat protection caused by electromagnetic interference.
[0029] Reference Figure 1 A ventilation pipe 12 is provided at the top of the cooling box 9, a fan 13 is provided at the top of the cooling box 9, and a heat sink 14 is provided on one side of the cooling box 9;
[0030] By adopting the above technical solution, since the electronic fluorine liquid will expand when overheated, the ventilation pipe 12 can ensure ventilation and pressure relief of the cooling box 9 to prevent the cooling box 9 from being damaged by excessive pressure due to expansion. The fan 13 can cool the cooling box 9, and the heat sink 14 can assist in cooling.
[0031] The implementation principle of the overheat protection device of an intelligent temperature control box in the embodiment of the present application is as follows: when the thermocouple 17 inside the temperature control box 1 detects that the temperature is too high, the rheostat 3 adjusts the current and voltage in the circuit to reduce the temperature of the intelligent temperature controller, and at the same time, the water pump 7 pumps the electronic fluorine liquid in the electronic fluorine liquid storage box 7 into the cooling pipe 8. Since the cooling pipe 8 is a curved structure inside the temperature control box 1, it can absorb heat evenly. The fan 5 at the bottom of the temperature control box 1 blows air to circulate the gas inside the temperature control box 1 to assist in cooling. The electronic fluorine liquid after absorbing heat is transmitted to the cooling box 9 for cooling. The electronic fluorine liquid is pumped into the electronic fluorine liquid storage tank 6 through the water pump 2 10 to perform circulation cooling, which has good cooling effect and saves resources. When the cooling effect cannot keep up with the temperature rise or the current is too large, the final power-off operation is performed through the relay 4. The seismic isolation pad at the bottom of the temperature control box 1 prevents the temperature controller 1 from being vibrated by external forces and causing the internal device to be falsely triggered. The filter 19 of the temperature control box 1 can reduce the false triggering of the overheating protection caused by electromagnetic interference. The use of this device can effectively reduce the damage to the internal components of the temperature controller caused by excessive internal temperature, and can reduce the occurrence of false triggering of the overheating protection device in various environments.
