The bottom surfaces of the lower guide rod 20 and the frame plate 18 are provided with supporting legs 4. A heat source inlet 5 is provided on the surface of the frame plate 18. A heat source outlet 7 is provided vertically at the bottom of the heat source inlet 5. A cold source inlet 6 is provided parallel to one side of the heat source inlet 5. A cold source outlet 8 is provided vertically at the bottom of the cold source inlet 6. The heat source outlet 7, the cold source inlet 6 and the cold source outlet 8 are all set on the frame plate 18. The heat source inlet 5, the heat source outlet 7, the cold source inlet 6 and the cold source outlet 8 all pass through the partition 3, the valve body 15 and the plate 9.

[0025] A partition 3 is provided in the middle of the plate 9, and multiple partitions 3 can be provided. Two valve bodies 15 are provided inside the partition 3, and a valve core 14 is provided inside the valve body 15. An upper sealing base 12 is provided on the valve core 14, and a valve stem 11 is provided on the top surface of the upper sealing base 12. A hand wheel 10 is provided at the end of the valve stem 11. When in use, the hot source fluid and the cold source fluid enter the heat exchanger from the hot source inlet 5 and the cold source inlet 6. The hot source fluid and the cold source fluid form multiple parallel flow channels in the plate 9 assembly and flow through these flow channels. When the hot source fluid and the cold source fluid flow in the flow channels, due to the temperature difference, heat begins to transfer. The heat of the hot source fluid is transferred to the cold source fluid through the plate 9, so that the temperature of the cold source fluid increases, while the temperature of the hot source fluid decreases. The hot source fluid and the cold source fluid are in a state of being heated and cooled. After the source fluid exchanges heat in the flow channel, it is discharged from the outlet pipe of the heat exchanger respectively. Due to the presence of the plate 9 assembly, the hot source fluid and the cold source fluid are separated and will not mix together. If the flow rate is small, the rear plate 9 can be rotated clockwise when it is not needed. The valve stem 11 moves forward to move the valve core 14 downward. Affected by the guide pin 13 in the spiral groove 17 of the valve stem 11, the valve core 14 begins to descend and rotate until it is completely closed. At this time, the valve is closed and the medium cannot circulate. In this way, there is no need to frequently disassemble the plate 9. Eight tightening screws 2, an upper guide rod 1 and a lower guide rod 20 are provided on the surface of the frame plate 18. The plate 9 is installed together through the upper guide rod 1, the lower guide rod 20 and the tightening screw 2 and fixed by the nut 22. Specific embodiment two:

[0027] Reference Figure 1-4 Filters can be provided on the surfaces of the heat source inlet 5 and the cold source inlet 6. When in use, the heat source fluid and the cold source fluid will pass through the filters before entering the internal plates 9 of the heat exchanger. When the heat source fluid and the cold source fluid are inside the filters, the minerals inside the heat source fluid and the cold source fluid will be neutralized and impurities in the fluid will be intercepted to prevent scaling when heating inside the heat exchanger, thereby causing blockage of the heat source fluid and the cold source fluid in the circulation of the plate 9 and affecting the heating efficiency.

[0028] In summary:

[0029] 1. A partition 3 is provided in the middle of the plate 9, and two valve bodies 15 are provided inside the partition 3. A valve core 14, an upper sealing base 12, and a valve stem 11 are provided inside the valve body 15. A handwheel 10 is provided on one side of the valve stem 11. When in use, the heat source and the cold source enter the plate 9 from the heat source inlet 5 and the cold source inlet 6 for heat exchange. If the flow rate is small, the handwheel 10 can be rotated clockwise when the rear plate 9 is not used. The positive movement of the valve stem 11 causes the valve core 14 to move downward. Affected by the guide pin 13 in the spiral groove 17 of the valve stem 11, the valve core 14 begins to descend and rotate until it is completely closed. At this time, the valve is closed and the medium cannot circulate. In this way, there is no need to frequently disassemble the plate 9, which solves the disadvantage of needing to disassemble the plate 9 according to the flow rate.
