DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0025] Reference Figure 1-6 The high-precision constant temperature and humidity control device comprises a body 1, an air intake grille 13 is arranged on one side of the body 1, a liquid inlet filter barrel 2 and a liquid outlet 21 are arranged on one side of the body 1 above the air intake grille 13, and a liquid return port 22 and a liquid outlet filter barrel 23 are arranged on the other side above the air intake grille 13. A water tank 4 is arranged inside the body 1, and the water tank 4 is connected with the liquid return port 22 and the liquid outlet filter barrel 23. A fan assembly 15 is arranged on the top of the body 1, and an air outlet 16 is arranged on the top of the fan assembly 15.
[0026] One end of the inlet filter barrel 2 is connected to a pipeline, the pipeline extends into the body 1 and is connected to the inlet end of the cooling tank 3, and the outlet end of the cooling tank 3 is connected to the outlet port 21 through a pipeline. Hot water from external equipment can be filtered through the inlet filter barrel 2 and then enter the cooling tank 3 for cooling. After cooling, the water flow returns to the external equipment through the outlet port 21.
[0027] Among them, a water pump 5 is fixedly arranged on the top of the water tank 4, and the liquid outlet of the water pump 5 is communicated with the large plate evaporator 6 through a pipeline. Through the arrangement of the water pump 5, the water flow in the water tank 4 can be input into the large plate evaporator 6.
[0028] The liquid outlet of the large plate evaporator 6 is connected to a liquid separator, one end of which is connected to the small plate evaporator 7, and the liquid outlet of the small plate evaporator 7 extends into the water tank 4. By setting the large plate evaporator 6 and the small plate evaporator 7, the water flow in the water tank 4 can be cooled, and the water flow after cooling is returned to the water tank 4.
[0029] The other end of the liquid separator extends into the first heater 8, and the first heater 8 is connected to the second heater 9 through a pipeline. After the large plate evaporator 6 cools the water flow, the water flows through the first heater 8 and the second heater 9 in sequence from the other end of the liquid separator, thereby realizing precise control of the temperature of the output water flow.
[0030] The second heater 9 is connected to the liquid outlet filter barrel 23 through a pipeline, and the liquid return port 22 is connected to the water tank 4 through a pipeline. The water flow heated by the second heater 9 can be input to the external device after being filtered through the liquid outlet filter barrel 23, and then the water flow passes through the external device and then enters the liquid return port 22, so that the water flow can flow back to the water tank 4.
[0031] Among them, a large compressor 12 is arranged inside the machine body 1, and the large compressor 12 is connected with the cooling tank 3, the large plate evaporator 6 and the small plate evaporator 7. Through the arrangement of the large compressor 12, it can be ensured that the cooling tank 3, the large plate evaporator 6 and the small plate evaporator 7 can cool the water flow.
[0032] Among them, a condenser 10 is arranged behind the air intake grille 13 in the machine body 1, and the condenser 10 is connected to a small compressor 11 in the machine body 1.

[0033] The fan assembly 15 is fixedly arranged on the top of the machine body 1, and an electric heating wire 14 is arranged inside the fan assembly 15. Through the arrangement of the electric heating wire 14 and the fan assembly 15, the wind entering from the inlet grille 13 can be heated to a suitable temperature and then output to the device end.
[0034] In this embodiment, the user can filter the water in the device through the liquid inlet filter barrel 2 and then input it into the cooling tank 3 for cooling. After the cooling is completed, the water flow returns to the device through the liquid outlet 21.
[0035] Furthermore, a water tank 4 is provided inside the machine body 1, and the water in the water tank 4 can be transported to the large plate evaporator 6 for cooling through the pump body 5. The water cooled by the large plate evaporator 6 enters the liquid separation pipe, which allows part of the water to enter the small plate evaporator 7 for further cooling. After the cooling is completed, the water flows back to the water tank 4, so that the water in the water tank 4 can be cooled.
[0036] The water flow in the large plate evaporator 6 can also enter the first heater 8 and the second heater 9 in sequence through the liquid separation pipe, so that the temperature of the cooling water flow can be accurately controlled, thereby ensuring the accuracy of the cooling water flow temperature. Then the water flow is filtered through the liquid outlet filter port 23 and enters the external equipment. After the equipment is cooled, it flows back to the water tank 4 through the liquid return port 22.
[0037] Furthermore, the workshop air can be input into the machine body 1 through the air intake grille 13, and the workshop air can be cooled by the condenser 10, and the air input into the machine body 1 and cooled can cool down the various components in the machine body 1. Then the gas passes through the fan assembly 15 and is output from the air outlet 16 to the external device. And by the arrangement of the electric heating wire 14, the temperature of the output air can be accurately controlled.
[0038] In the present embodiment, water flow can be circulated through the liquid inlet filter barrel 2, the liquid outlet 21, the liquid return port 22, the liquid outlet filter barrel 23 and the pipeline in the body 1. The water flow can be cooled by the setting of the cooling tube 3, the large plate evaporator 6 and the small plate evaporator 7, and the output cooling water flow can be accurately temperature controlled by the setting of the first heater 8 and the second heater 9; the air flow can be circulated by the setting of the air intake grille 13 and the air outlet 16, and the air flow can be cooled by the cooler 10. The cooled air flow can be re-input into the external device after cooling the components inside the body 1, and the output air flow can be accurately and stably controlled by the setting of the electric heating wire 14. This method not only accurately controls the temperature, but also can cool the device itself.
