The bypass valve 46 is configured to open the secondary line 45 when the pressure value of the coolant in the main line 41 is greater than a pressure preset range value, and is adapted to discharge a portion of the coolant in the main line 41 to the Container 3.

The heat exchange unit 5 has a cooling line 51 adapted to supply a refrigerant, a compression motor 52 forming a circulation loop through the cooling line 51, a condensation group 53, a dryer 54, an expansion valve 55, and a heat. The exchanger 56 is connected to a split line 57 communicating with the cooling line 51, and a proportional valve 58 communicating with the split line 57 and opening the split line 57 open.

The compression motor 52 is suitable for compressing a low-temperature low-pressure gaseous refrigerant into a high-pressure high-temperature gaseous refrigerant.

The condensation group 53 is suitable for heat exchange with a high-pressure high-temperature gaseous refrigerant, so that the high-pressure high-temperature gaseous refrigerant becomes a normal-temperature high-pressure gaseous refrigerant. The condensation group 53 has a condenser 531 through which the cooling line 51 passes, and a fan 532 mounted on the condenser 531 and guiding the outside airflow through the condenser 531.

The dryer 54 is adapted to filter moisture and impurities in the cooling line 51.

The proportional valve 58 is configured to control the flow rate of the high-temperature high-temperature gaseous refrigerant into the heat exchanger 56, and can be turned on or off when the temperature value of the coolant in the main line 41 does not meet the preset value of the water temperature. The branch line 57 allows high-temperature refrigerant to enter or not pass through the heat exchanger 56 for the purpose of controlling the temperature.

The electronic control unit 6 includes a connection interface 61, a programmable control board 62 that is pluggably electrically connected to the connection interface 61, a driver board 63 and an AC adapter board 64, and four Temperature sensor 65~66.

The control board 62 is programmable and electrically connected to the expansion valve 55, the proportional valve 58, and includes a wireless communication module 621.

The AC/DC converter board 64 is pluggably and electrically connected to the connection interface 61 and is used to supply the required power.

The temperature sensors 65, 66 are used to detect the temperature of the coolant in the output line 42 and the input line 43.

The temperature sensor 67 is mounted in a cooling line 51 between the compression motor 52 and the condensation group 53 for detecting the temperature of the refrigerant before entering the condensation group 53.

The temperature sensor 68 is mounted in a cooling line 51 between the expansion valve 55 and the heat exchanger 56 for detecting the temperature of the refrigerant before entering the heat exchanger 56.

During the heat exchange, the pump group 44 sucks the coolant in the container 3 into the main pipe 41, so that the coolant passes through the heat exchanger 56 according to the main pipe 4, and the coolant passing through the heat exchanger 56 is passed. The heat exchange with the refrigerant in the heat exchanger 56 is maintained at a low temperature. Thereby, the low temperature coolant is output to the hot zone 21 via the output line 42, so that the hot zone 21 achieves the effect of cooling or temperature control.

Then, the coolant for temperature control is guided from the hot zone 21 to the vessel 3 through the input line 43. In this manner, the coolant in the container 3 can be heat-exchanged with the refrigerant in the heat exchanger 46 before the output of the hot zone 21, while maintaining the low temperature or the required temperature.

At the same time, the heat exchange unit 5 compresses the low-temperature low-pressure gaseous refrigerant into a high-pressure high-temperature gaseous refrigerant through the compression motor 52, and then exchanges heat with the high-pressure high-temperature gaseous refrigerant through the condensation group 53, so that the high-pressure high-temperature gaseous refrigerant becomes the normal temperature. The high-pressure gaseous refrigerant is then passed through the expansion valve 55 to lower the normal temperature and high pressure gaseous refrigerant into a low-temperature low-pressure refrigerant, so that the low-temperature low-pressure refrigerant enters and exits the heat exchanger 56 through the cooling line 51, and passes through the The coolant of the heat exchanger 56 is heat exchanged to maintain the coolant in the vessel 3 at a low temperature or a desired temperature.

It should be noted that the control board 62 can control the heat exchange efficiency of the heat exchange unit 5 through the driver board 63, and further change the temperature of the coolant. For example, when the temperature sensor 66 (or the temperature sensor 65) senses that the temperature of the coolant in the input line 43 (or the output line 42) is higher than a preset value of a cooling temperature, and returns When the controller board 62 is transmitted to the control board 62, the controller board 62 can control the air volume of the fan 532 or the cooling effect of the expansion valve 55, thereby improving the heat exchange efficiency of the heat exchanger 56. Cool the coolant or maintain a constant temperature.

Importantly, the control plate 62 can also control the flow rate of the high temperature refrigerant entering the heat exchanger 56 through the proportional valve 58, and further control the heat exchange efficiency of the heat exchanger 56. For example, when the temperature sensor 68 senses that the temperature of the refrigerant in the cooling line 51 is lower than a preset value of a heat exchange temperature, the control board 62 can block the shunt tube through the proportional valve 58. The passage 57 is partially opened or the high-temperature refrigerant enters the heat exchanger 56 or does not pass through the heat exchanger 56, thereby cooling the coolant or heating the coolant through refrigerant having different temperature changes. Or maintain the constant temperature effect to achieve the purpose of controlling the temperature of the coolant.

Moreover, when the temperature sensor 67 senses that the temperature of the refrigerant in the cooling line 51 is higher than a preset temperature of the refrigerant, and returns it to the control board 62, the control board 62 can pass the The drive plate 63 controls the compression motor 52 to reduce the rotational speed, preventing the high temperature refrigerant temperature from being too high, and forming a protective mechanism.

In addition, the control board 62 can transmit information such as the coolant temperature, the refrigerant temperature, the compression motor 52, and the usage time of the pump group 44 to the remote end through the wireless communication module 621 to achieve remote monitoring.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. The present invention can be modularized, so that the control board 62, the driver board 63 and the AC/DC converter board 64 are independent of each other, and not only can the machine board that meets the requirements be replaced according to the function of use, so that The configuration of the internal space is more maneuverable, and when any of the boards is damaged, only one of the boards can be replaced, and the maintenance cost can be reduced.

2. Through the variable frequency compression motor 52, the variable frequency fan 532, and the temperature sensing of the temperature sensors 67 and 68, the control panel 62 can pass the refrigerant of different temperatures at different temperatures through the proportional valve 58.
