On one side of both of the two three - way water valves 1, there are a first support frame 5 and a second support frame 7, and both the first support frame 5 and the second support frame 7 are established on the frame plate 3. On one side of both of the two three - way water valves 1, there is a centrifugal water pump 8, and the centrifugal water pump 8 is installed on the second support frame 7. On one side of both of the two centrifugal water pumps 8, there is a rotating motor 21, and the rotating motor 21 is installed on the first support frame 5. On one side of both of the two rotating motors 21, there is a rotating rod 19, and one end of the rotating rod 19 penetrates through the centrifugal water pump 8. On the surface of both of the two rotating rods 19, five impellers 20 are arranged around, and the impellers 20 are established inside the centrifugal water pump 8. On the surface of the frame plate 3, there is an upper guide rod 12, and the upper guide rod 12 is established on the side far from the heat source inlet 6. At the bottom of the upper guide rod 12, there is a lower guide rod 15, and the upper guide rod 12 and the lower guide rod 15 are in a vertical state. On both sides of the upper guide rod 12, four tightening screws 11 are vertically provided, and one end of each tightening screw 11 is installed on the frame plate 3. On one side of the frame plate 3, there is a plate fin 18, and the plate fin 18 is installed on the upper guide rod 12 and the lower guide rod 15. On one side of the plate fin 18, there is a pressing plate 10, and the pressing plate 10 is established on the side far from the frame plate 3. The pressing plate 10 is installed on the upper guide rod 12 and the lower guide rod 15, and all eight tightening screws 11 penetrate through the pressing plate 10. On one side of the pressing plate 10, there are eight nuts 14, and the nuts 14 are evenly installed on the tightening screws 11.

[0026] On one side of both the heat source inlet 6 and the cold source inlet 4, a three-way water valve 1 is provided. On one side of each three-way water valve 1, a centrifugal water pump 8 is provided, and the two centrifugal water pumps 8 are in a diagonal state. Inside the three-way water valve 1, there is a valve core 16. On the top surface of the valve core 16, there is a valve stem 17. One end of the valve stem 17 penetrates through the three-way water valve 1. On the top surface of the valve stem 17, there is a handwheel 13. When it is necessary to control the temperature of the hot fluid when it is discharged, the handwheel 13 of the three-way water valve 1 close to the heat source inlet 6 can be rotated clockwise, so that the handwheel 13 drives the valve stem 17 to rotate and indirectly drives the valve core 16 to rotate, making the valve core 16 rotate to the right. At this time, the fluid can only enter the heat source inlet 6 through the right channel. A centrifugal water pump 8 is provided in the right channel of the three-way water valve 1 close to the heat source inlet 6, and the centrifugal water pump 8 of the three-way water valve 1 close to the cold source inlet 4 is provided in the left channel of the three-way water valve 1. At this time, the centrifugal water pump 8 can be started. The centrifugal water pump 8 is connected to the power supply. When it is turned on, the rotating motor 21 drives the rotating rod 19 to rotate, and the impeller 20 rotates accordingly. The high-speed rotation of the impeller 20 causes the water to be thrown to the outer edge of the impeller 20 under the action of centrifugal force and enter the right flow channel of the three-way water valve 1 from the centrifugal water pump 8. The hot fluid entering at high speed from the heat source inlet 6 will quickly pass through the heat exchanger, reducing the heat exchange with the cold fluid, so that the hot fluid is still at a relatively high temperature when it is discharged from the heat source outlet 9. The user can indirectly control the speed and time of the hot fluid when it is discharged from the heat source outlet 9 by controlling the rotation speed of the centrifugal water pump 8 according to specific selections, thereby controlling the temperature of the hot fluid when it is discharged from the heat source outlet 9. When it is not desired to control the temperature for normal heat exchange, the handwheel 13 can be rotated counterclockwise to make the valve core 16 rotate to the left. At this time, the fluid can only enter the heat exchanger through the left channel. When it is necessary to control the temperature of the cold fluid when it is discharged from the cold source outlet 2, the temperature of the cold fluid discharged from the cold source outlet 2 can be controlled by operating in the reverse direction according to the above method. On the surface of the frame plate 3, there is an upper guide rod 12. At the bottom of the upper guide rod 12, there is a lower guide rod 15, and the upper guide rod 12 and the lower guide rod 15 are in a perpendicular state. On both sides of the upper guide rod 12, four tightening screws 11 are vertically provided. On one side of the frame plate 3, there is a plate 18 and a pressing plate 10, and the plate 18 and the pressing plate 10 are installed on the upper guide rod 12 and the lower guide rod 15. The eight tightening screws 11 penetrate through the pressing plate 10. On one side of the pressing plate 10, there are eight nuts 14, and the nuts 14 are evenly installed on the tightening screws 11, so that the pressing plate 10 tightly installs the plate 18 together. When using the heat exchanger, the hot fluid and the cold fluid enter the plate 18 from the heat source inlet 6 and the cold source inlet 4 for heat exchange. When the heat exchange is completed, the hot fluid and the cold fluid are discharged from the heat source outlet 9 and the cold source outlet 2 to complete the heat exchange. Specific Embodiment Two:

[0028] Refer to Figures 1-5, the three-way water valve 1 can be replaced with a three-way solenoid valve. The three-way solenoid valve is installed on the heat source inlet 6 and the cold source inlet 4 through a flange ring. When the electromagnet is energized, a magnetic force will be generated in the magnetic field where the electromagnet is located. This magnetic force will attract the valve core 16 to the port of the electromagnet. At this time, the centrifugal water pump 8 is started, so that the hot fluid enters the heat source inlet 6 through the centrifugal acceleration of the centrifugal water pump 8. When the electromagnet is de-energized, the valve core 16 will return to its original state. At this time, the fluid will flow in different states according to the position of the valve core 16.

[0029] In summary:

[0030] 1. A three-way water valve 1 is provided on one side of both the heat source inlet 6 and the cold source inlet 4. A centrifugal water pump 8 is provided on one side of the three-way water valve 1. A valve core 16 is provided inside the three-way water valve 1. A valve stem 17 is provided on the top surface of the valve core 16, and a handwheel 13 is provided on the top surface of the valve stem 17. When temperature control is required during use, the handwheel 13 can be rotated clockwise to drive the valve stem 17 and indirectly drive the valve core 16 to rotate, so that the valve core 16 rotates to the right. At this time, the fluid can only enter the heat source inlet 6 through the right channel. A centrifugal water pump 8 is provided in the right channel of the three-way water valve 1 near the heat source inlet 6. At this time, the centrifugal water pump 8 can be turned on, and the rotating motor 21 drives the pump shaft to rotate, and the impeller 20 rotates accordingly. The high-speed rotation of the impeller 20 causes the water to be thrown towards the outer edge of the impeller 20 under the action of centrifugal force and enter the flow channel of the three-way water valve 1. The hot fluid entering at high speed from the heat source inlet 6 will quickly pass through the heat exchanger, reducing heat exchange with the cold fluid, so that the hot fluid is still at a relatively high temperature when it is discharged from the heat source outlet 9. Users can indirectly control the temperature of the hot fluid discharged from the heat source outlet 9 by controlling the rotation speed of the centrifugal water pump 8 according to specific selections. The cold fluid is operated in the reverse manner as described above.
