DETAILED DESCRIPTION

[0035] Here, exemplary embodiments will be described in detail, and the embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are only examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0036] Example

[0037] like Figure 1-8 As shown, a field insulation box includes a box body 1 and an electronic control system 4 for controlling the box body temperature. A refrigeration system 2 is provided in a functional area 1.1 at the lower portion of the box body 1. A storage area 1.2 and a heating system placement area are provided above the functional area 1.1. The heating system placement area is located on one side of the storage area 1.2, and the storage area 1.2 and the heating system placement area are isolated from each other. A cold air discharge channel is provided between the functional area and the heating system placement area. A heating system 3 is provided in the heating system placement area. The electronic control system 4 adjusts the temperature by controlling the refrigeration system 2 and the heating system 3 and maintains the temperature within a constant range.

[0038] Furthermore, the heating system 3 includes a first evaporator 3.1 and a first circulation fan 3.2. A heating wire is wound around the first evaporator 3.1. A first circulation fan 3.2 is provided on one side of the first evaporator 3.1 to discharge hot air into the storage area 1.2. The heating system is a PTC heating system.

[0039] In this embodiment, the heating wire is a low-temperature silicone heating wire, which is wound around the pipeline of the first evaporator 3.1. When energized, the surface of the heating wire generates a temperature of approximately 70°C and transmits the temperature to the pipeline of the first evaporator 3.1 to increase the heat exchange area. The circulating fan 3.2 installed at the front end of the first evaporator 3.1 circulates and discharges hot air into the interior of the storage area 1.2, thereby achieving the purpose of increasing the temperature inside the storage area 1.2.

[0040] Furthermore, the refrigeration system 2 includes a second evaporator, a compressor 2.3, a condenser 2.2, and a condensing fan 2.1. The compressor 2.3 is connected to the condenser 2.2 through an exhaust pipe, the condenser 2.2 is connected to the throttling device through a first pipe, and the throttling device is connected to the tubular evaporator through a second pipe. The condensing fan 2.1 is located on one side of the condenser 2.2, and the high temperature inside the condenser 2.2 is discharged to the outside of the box 1 through the condensing fan 2.1.

[0041] In this embodiment, the refrigeration process of the refrigeration system 2 includes the following processes:

[0042] 1. Inhalation: After the compressor 2.3 is powered on, the internal motor of the compressor 2.3 drives the rotor inside the compressor 2.3 to rotate, generating negative pressure and sucking in the low-temperature and low-pressure refrigerant gas at the bottom of the compressor 2.3.

[0043] 2. Compression: The compressor 2.3 compresses the sucked refrigerant gas into high-temperature and high-pressure gas, thereby increasing the pressure of the refrigerant gas.

[0044] 3. Condensation: The high-temperature and high-pressure refrigerant gas releases heat through the condenser 2.2 and cools into liquid. The high temperature inside the condenser 2.2 is discharged to the outside of the cabinet 1 through the condensing fan 2.1.

[0045] 4. Expansion: The liquid refrigerant passes through the capillary tube throttling and becomes a low-pressure, low-temperature refrigerant gas, which enters the tubular evaporator. The second circulation fan circulates the cold air inside the tubular evaporator to the interior of the box 1, thereby reducing the temperature inside the box. The second evaporator is a tubular evaporator.

[0046] Furthermore, ventilation holes are provided on the rear wall of the functional area 1.1 and the side walls around the condensing fan 2.1.

[0047] Furthermore, the electronic control system 4 includes a control panel 7 and a control center. The control panel 7 is provided on the outer surface of the box 1 , and the target temperature data is input through the control panel 7 .

[0048] Furthermore, the control center is located behind the control panel 7 .

[0049] Furthermore, the box body 1 is made of waterproof rotational molding material, and a rubber pad is provided at the bottom of the box body 1.

[0050] Waterproof roto-molded materials such as polyethylene, polyvinyl chloride (PVC), polycarbonate (PC), etc.

[0051] Furthermore, the electronic control system further includes a temperature sensor, through which temperature information is transmitted to the electronic control system in real time.

[0052] In this embodiment, the electronic control system 4 includes a temperature sensor, an MCU main control circuit, a power management circuit, a key display control circuit, a data reading circuit, a relay control circuit, a temperature sampling and calculation circuit, an electromagnetic compatibility circuit, and system control software. The temperature sensor transmits temperature information to the electronic control system in real time.

[0053] The electronic control system 4 works by comparing the temperature of the storage area 1.2 obtained by calculating the sampled data from the temperature sensor and the MCU system software with the user-set temperature value entered via the control panel 7 button and stored in the system's internal memory. Based on the temperature comparison result, the compressor 2.3 is instructed to operate the cooling system or the heating system. The specific control process is as follows:

[0054] 1. Refrigeration - When the temperature of storage area 1.2 exceeds the set temperature set on control panel 7 by 2°C, the software system instructs the compressor driver board to output three-phase DC power to power the compressor through the relay control circuit. The system software controls compressor 2.3 to perform variable frequency starting. The speed of the motor inside compressor 2.3 gradually increases from 0% to 100% within 1 minute. Compressor 2.3 enters full load operation, the refrigeration system begins cooling, and the secondary circulation fan and condenser fan 2.1 begin to circulate air within the chamber. When the temperature of storage area 1.2 reaches the set temperature, the software system instructs the compressor 2.3 driver control board to stop providing three-phase DC power to compressor 2.3. Refrigeration system 2 and the fans stop operating, and the system enters the standby and heat preservation stage. When the temperature of storage area 1.2 exceeds the set temperature set on control panel 7 by 2°C (i.e., storage area 1.2 temperature - set temperature = 2°C), the refrigeration system starts again, aiming to maintain the temperature at the set temperature (within a fluctuation of 2°C).

[0055] 2. Heating - When the temperature of the box 1 is 2°C lower than the ambient temperature, the software system connects the power supply of the heating wire and the circulation fan through the relay control circuit. The heat generated by the heating wire is discharged into the interior of the box 1. When the temperature inside the box reaches the set temperature, the heating system stops working and the system enters the standby insulation stage. When the temperature of the storage area 1.2 is 2°C lower than the set temperature set on the control panel 7 (i.e.: set temperature - temperature of storage area 1.2 = 2°C), the heating system starts again with the aim of always maintaining the temperature at the set temperature (within a fluctuation range of 2°C).

[0056] Data reading circuit: Through the data reading button on the control panel 7 and the waterproof USB interface, the information stored in the MCU main control board, such as the box temperature, ambient temperature and system fault code sampled and stored every 5 minutes, can be read out and decoded using dedicated host computer software, making it convenient for users to view the historical working status of the equipment.

[0057] The keys / buttons on the control panel 7 include: a main power button, a data button, an on / off button, a cooling / heating button, a setting button, a normal temperature button, and a refrigeration button.

[0058] The control panel 7 is provided with a display screen, which displays the temperature in real time.

It displays ON when it is turned on, and the temperature inside the box will be displayed in normal status. The setting interface will display the temperature setting and time setting interfaces; the control panel is provided with a system heating indicator light, a system cooling indicator light, and for data import, a red light will be displayed when the import starts, a green light will be displayed when the import is successful, and all lights will be off when the import is not completed or the U disk recognition fails; the electronic control system 4 is provided with a buzzer, which will beep briefly when pressing a button or turning the machine on and off, and will beep long when a new fault occurs in the equipment; the system can export the data stored in the FLASH to the U disk according to the protocol, and the data includes time, temperature, Degree and fault code data; the electronic control system is equipped with a temperature control module. The temperature control module has insulation and refrigeration functions, controlling the temperature difference at ±2°C. The first evaporator 3.1 fan is turned on with a delay of 1 minute. The temperature control module mainly controls the temperature sensor, the temperature inside the box and the ambient temperature. In insulation mode, the temperature is kept at 30°C, and in refrigeration mode, the temperature is kept at 4°C; for the setting button, a long press will display the setting interface, and a short press will turn the setting interface and display the non-setting interface, with the ambient temperature and the set temperature appearing on the non-setting interface; for the up button, a long press will display the setting interface - quick parameter adjustment, the non-setting interface is insulation mode, and a short press will adjust the parameters; for the down button, a long press will display the setting interface - quick parameter adjustment, the non-setting interface is refrigeration mode, and a short press will adjust the parameters; export button, long press to export.

[0060] The temperature control range is 2~40℃, which can effectively adjust, control and maintain a constant temperature in the storage space.

[0061] Furthermore, the functional area 1.1 and the storage area 1.2 are connected via a second hinge 5.
