When the water temperature in the confluence chamber is higher than the set value, the valve is opened to continue the input of cold water, increase the water level in the confluence chamber, so that the water flow can flow over the top of the second partition and flow into the diversion chamber, and continue to be heated in the process of flowing downward through the second heat conducting pipe, thereby ensuring the high water temperature in the water outlet chamber and completely avoiding the problem of low-temperature cold water outflow. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0015] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.

[0016] like Figure 1The vertical non-cold water heat exchanger shown includes: a cylinder 1, a controller 21, a valve 9, a temperature sensor 17, a liquid level sensor 16, a first heat conducting pipe 10, a second heat conducting pipe 14, a water inlet pipe joint 8, a water outlet pipe joint 13, a hot fluid inlet 11, a hot fluid outlet 12, a first cover 4 and a second cover 2, wherein the first cover 4 is arranged at the bottom of the vertically placed cylinder 1, and the second cover 2 is arranged at the top of the cylinder 1. In this embodiment, the first cover 4 is provided with a first screw 22 connected to the bottom of the cylinder 1, and the second cover 2 is provided with a second screw 23 connected to the top of the cylinder 1. The structure is stable and disassembly and maintenance are relatively convenient. In addition, the vertical structure is adopted, which effectively reduces the floor space.

[0017] A first plugging plate 6 is provided at the bottom of the inner hole of the cylinder 1, which is welded and sealed, has a stable structure and good anti-seepage effect. A first partition plate 5 extending upward to the first plugging plate 6 is provided at the bottom of the inner cavity of the first cover 4, so as to form a mutually isolated water inlet cavity 7 and a water outlet cavity 20 on both sides of the first partition plate 5. The water inlet pipe joint 8 is provided on one side of the first cover 4 and is connected to the water inlet cavity 7, so that low-temperature cold water can be introduced into the water inlet cavity 7. In this embodiment, the valve 9 is provided on the water inlet pipe joint 8 to control the introduction of low-temperature cold water. The water outlet pipe joint 13 is provided on one side of the first cover 4 and is connected to the water outlet cavity 20 to allow high-temperature water to flow out.

[0018] like Figure 1 As shown, a second plugging plate 19 is provided at the top of the inner hole of the cylinder 1, and the second plugging plate 19 is welded and fixed at the top of the inner hole of the cylinder 1, and has good sealing performance. A second baffle 3 is provided in the second cover 2, which is parallel to the first baffle 5 and the bottom is in contact with the second plugging plate 19, so as to form a confluence chamber 18 and a diversion chamber 15 on both sides of the second baffle 3. The first heat-conducting pipe 10 is vertically arranged in the cylinder 1 and connects the confluence chamber 18 with the water inlet chamber 7. The second heat-conducting pipe 14 is vertically arranged in the cylinder 1 and connects the diversion chamber 15 with the water outlet chamber 20. In this embodiment, the first plugging plate 6 is provided with first through holes corresponding to the bottoms of the first heat-conducting pipe 10 and the second heat-conducting pipe 14. The bottoms of the first heat-conducting pipe 10 and the second heat-conducting pipe 14 are inserted into the corresponding first through holes and fixed by welding, and the structure is stable.

[0019] The second sealing plate 19 is provided with second through holes corresponding to the tops of the first heat conducting tube 10 and the second heat conducting tube 14. The tops of the first heat conducting tube 10 and the second heat conducting tube 14 are inserted into the corresponding second through holes and fixed by welding to prevent leakage. In this embodiment, the water inlet cavity 7 is located directly below the confluence cavity 18, and the water outlet cavity 20 is located directly below the diversion cavity 15, which is conducive to keeping the first heat conducting tube 10 and the second heat conducting tube 14 vertical.

[0020] The hot fluid inlet 11 and the hot fluid outlet 12 are respectively arranged on the outside of the cylinder 1. Hot fluid such as steam or hot oil can be introduced into the cylinder 1 through the hot fluid inlet 11 and discharged through the hot fluid outlet 12. When passing through the first heat conducting pipe 10 and the second heat conducting pipe 14, the heat is transferred to the water flow in the first heat conducting pipe 10 and the second heat conducting pipe 14.

[0021] The temperature sensor 17 and the liquid level sensor 16 are arranged on the second cover 2 and extend downward into the confluence chamber 18 to detect the water temperature and water level in the confluence chamber 18. In this embodiment, the valve 9, the temperature sensor 17 and the liquid level sensor 16 are respectively connected to the controller 21 for automatic control.

[0022] There is a gap between the top of the second partition 3 and the top of the second cover 2, and when the water level in the confluence chamber 18 is higher than the top of the second partition 3, the water can flow into the diversion chamber 15. When the water temperature in the confluence chamber 18 is lower than the set value, the controller 21 closes the valve 9 to prevent the continued input of cold water, maintains the water level in the confluence chamber 18 lower than the second partition 3, and continues to use the hot fluid in the cylinder 1 to heat the cold water in the first heat-conducting pipe 10. When the water temperature in the confluence chamber 18 is higher than the set value, the valve 9 is opened to continue the input of cold water, and the water level in the confluence chamber 18 is raised, so that the water flow can flow over the top of the second partition 3 and flow into the diversion chamber 15, and continue to be heated in the process of flowing downward through the second heat-conducting pipe 14, ensuring the high water temperature in the water outlet chamber 20, and completely avoiding the problem of low-temperature cold water flowing out of the water outlet pipe joint 13.
