[0017] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Example

[0018] refer to Figures 1 to 2 Example 1 describes a system including a stabilizing base 1, on which a control cabinet 2 is fixedly mounted. Two sets of circulating pumps 3 are mounted on the stabilizing base 1, and circulating pipes 4 are connected to the circulating pumps 3. The circulating pipes 4 are connected to a water supply pump 5, and an inlet pipe 6 is connected to the other side of the water supply pump 5, which is connected to a water tank. A water level sensor 25 for water level monitoring is installed in the water tank and is connected to the control cabinet 2. A plate heat exchanger 7 is mounted on the stabilizing base 1 and is connected to the circulating pipe 4 on the circulating water pump. A thermometer 12 is connected to one side of a second temperature sensor 14, a pressure gauge 10 is connected to one side of a pressure sensor 16, and a first temperature sensor 9 is connected to one side of the plate heat exchanger 7. The first temperature sensor 9 is connected to the control cabinet 2. A filter 11 is installed in the circulating pipe 4, and a ball valve 13 is installed between the circulating pipe 4 and the filter 11. In this embodiment, the plate heat exchanger 7 and the control cabinet 2 are connected by a PLC control system to realize automatic control and monitoring of the heat exchange unit. The control system has the functions of collecting and displaying parameters such as temperature, pressure and flow, as well as fault alarm and protection functions. Example

[0019] refer to Figure 2 Example 2 further illustrates Example 1, including the following: a check valve 22 and a solenoid valve 23 are respectively installed at the connection end of the water pump 5 and the water inlet pipe 6. One end of the water inlet pipe 6 is connected to the converter 21, and the converter 21 is connected to the control cabinet 2. A butterfly valve 24 and a safety valve 20 are installed on the circulation pipe 4 of the circulating water pump. One end of the safety valve 20 is connected to the steam trap 18 through the circulation pipe 4. A steam trap 19 and an air vent 17 are respectively installed on the steam trap 18. A pressure sensor 16, an electric valve 15, and a second temperature sensor 14 are respectively installed at the pipe of the steam trap 18, and the pressure sensor 16, the electric valve 15, and the second temperature sensor 14 are connected to the control cabinet 2. In this embodiment, the plate heat exchanger 7 can continuously and stably provide hot water, and the real-time temperature can be detected by a temperature sensor.

[0020] In practical applications, water is introduced into the water tank via the water supply pump 5. The introduced water is then continuously circulated by the dual circulation pump 3, providing pressure and power support, circulating the fluid, and improving its quality and stability. When the water level sensor 25 detects the water level, if it is lower than the set value, the water tank is automatically replenished with constant pressure to ensure stable unit pressure. By circulating water into the plate heat exchanger 7, the heat of the high-temperature fluid is transferred to the low-temperature fluid, achieving effective heat energy conversion. This allows the plate heat exchanger 7 to continuously and stably provide hot water. The real-time temperature can be detected by a temperature sensor. The plate heat exchanger 7 and the control cabinet 2 are connected by a PLC control system to achieve automatic control and monitoring of the heat exchange unit. The system has functions for collecting and displaying parameters such as temperature, pressure, and flow rate, as well as fault alarm and protection functions. When the plate heat exchanger 7 has been used for a long time or is damaged and needs to be replaced, the screws on the bottom limit block can be removed to facilitate disassembly and assembly of the heat exchanger. The entire process uses automated water supply and replenishment, ensuring the practicality of the device.
