Detailed Implementation

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figures 1-4 As shown in this embodiment, a rapid heat exchange device for heating includes an inlet 1, an outlet 2, and a heat exchange channel 3. The inlet 31 and outlet 32 ​​of the heat exchange channel 3 are connected to the inlet 1 and outlet 2, respectively. The heat exchange channel 3 is composed of an inner channel and an outer channel, and a water-reducing layer is provided on the inner and / or outer channel. The device includes an inlet, an outlet, and a heat exchange channel, wherein the inlet and outlet of the heat exchange channel are connected to the inlet and outlet, respectively, ensuring unobstructed water flow. The heat exchange channel is composed of an inner channel and an outer channel, a design that facilitates subsequent drag reduction. To reduce water resistance, this solution creatively provides a water-reducing layer on the inner and / or outer channel. This water-reducing layer can effectively reduce the friction coefficient between the water flow and the wall of the heat exchange channel, thereby reducing water resistance and improving water flow efficiency. Specifically, the water-reducing layer may use special materials or coatings with smooth surfaces and low friction characteristics, which can significantly reduce energy loss of water flow when passing through the heat exchange channel. This design not only improves heat exchange efficiency but also ensures the stability and reliability of the water dispenser during use, providing users with a more efficient and convenient drinking experience. In this embodiment, a water-resistance-reducing layer is provided on the inner side of the channel.

[0029] Preferably, the water-blocking component 4 and the heat exchange cylinder 5 are included, the water-blocking component 4 is inserted into the inside of the heat exchange cylinder 5, and a heat exchange channel 3 is formed between the outer surface of the water-blocking component 4 and the inner surface of the heat exchange cylinder 5. At this time, the inlet 31 and the outlet 32 of the heat exchange channel 3 are located on the water-blocking component 4, respectively. This technical solution innovatively constructs a heat exchange channel by inserting the water-blocking component into the inside of the heat exchange cylinder. This design not only simplifies the structure of the heat exchange device and reduces the production cost, but also improves the heat exchange efficiency. The close fit between the water-blocking component and the heat exchange cylinder ensures the stable flow of water in the heat exchange channel, avoiding heat loss caused by turbulent water flow. At the same time, the plug-in design of the water-blocking component also facilitates the maintenance and replacement of the device in the later stage, reducing the maintenance cost. In addition, this structure can effectively prevent the accumulation of scale and impurities, prolonging the service life of the heat exchange device. Specifically, the heat exchange cylinder of the embodiment is a heating cylinder. The heating wire is wound outside the heat exchange cylinder. The heating wire is simple to set and has low space utilization requirements, and the heating speed is fast, which is very useful for scenes that need to be heated quickly and can improve the heating efficiency.

[0030] Preferably, the material of the water-blocking component 4 is ceramic. The surface of ceramic is smooth, that is, the surface of the water-blocking component itself is the water-reducing layer 41. Moreover, ceramic material has excellent high-temperature resistance and chemical stability, and can maintain stable physical and chemical properties in high-temperature environment, without deformation, damage or odor generation due to long-term high-temperature use. At the same time, the ceramic material also has good corrosion resistance and wear resistance, which can resist the erosion of scale and impurities, and maintain the cleanliness and efficient operation of the water-blocking component. In addition, the thermal conductivity of ceramic material is moderate, which can effectively transfer heat and improve the heat exchange efficiency.

[0031] Preferably, the heat exchange channel 3 is spiral. The spiral design not only effectively increases the contact area of water flow and heating element, thereby improving the heat exchange efficiency and rapidly raising the water temperature, but also slows down the water flow speed to some extent, making the heat distribution more uniform and avoiding the problem of local overheating or uneven cooling. In addition, the spiral channel can effectively utilize space, making the structure of the entire heat exchange device more compact and facilitating installation and maintenance. This design also enhances the stability and durability of the device, as the spiral channel can reduce the direct impact of water flow on the inside of the device, prolonging the service life. In the embodiment, the spiral heat exchange channel is realized by setting a threaded channel on the surface of the water-blocking component 4.

[0032] Specifically, the first end cover 6 and the second end cover 7 are further included, the first end cover 6 is connected with the first end of the heat exchange cylinder 5, the second end cover 7 is connected with the last end of the heat exchange cylinder 5, the water inlet 1 is arranged in the first end cover 6, and the water outlet 2 is arranged in the second end cover 7. The design of the first end cover and the second end cover not only enhances the sealing performance and stability of the device, but also effectively prevents water leakage and heat loss. At the same time, the water inlet and the water outlet are arranged in the first end cover and the second end cover respectively, so that the flow path of the water flow in the device is more clear and controllable, and the heat exchange efficiency is improved. In addition, this design also facilitates the user to install and disassemble, and reduces the operation difficulty.

[0033] Preferably, the first end cover 6 and the water blocking assembly 4 are integrally formed. This design not only simplifies the production process, reduces the production cost, but also improves the overall performance and stability of the device. There is no gap or interface between the integrally formed first end cover and the water blocking assembly, which effectively prevents water leakage and heat loss. At the same time, this design can also enhance the durability and corrosion resistance of the device, prolonging the service life.

[0034] Preferably, the roughness of the water reducing resistance layer is ≤20 microns. The roughness ≤20 microns can ensure that the friction between the water flow and the water reducing resistance layer is minimized when passing through the heating channel, thereby effectively reducing the water resistance, improving the water flow speed, and making the heat transfer more rapid. At the same time, this roughness can also maintain the smoothness and durability of the surface of the water reducing resistance layer, avoiding wear or deformation due to long-term use. In addition, the roughness ≤20 microns can also match the shape and material of the heating channel, ensuring the stability and efficiency of the entire heat exchange process.

[0035] Preferably, a leakage-proof sealing ring 8 is further arranged between the first end cover 6 and / or the second end cover 7 and the heat exchange cylinder 5. The sealing ring can effectively fill the small gap between the first end cover, the second end cover and the heat exchange cylinder, preventing water leakage and heat loss. At the same time, the sealing ring can also withstand certain pressure and temperature fluctuations, ensuring that the device can still operate stably under high temperature and high pressure environment. In addition, the material selection and size design of the sealing ring have also been strictly tested and verified to ensure that it can tightly fit with the first end cover, the second end cover and the heat exchange cylinder, improving the reliability and durability of the device. Preferably, the material of the sealing ring 8 is silicone rubber. Silicone rubber material has excellent high temperature resistance and chemical stability, can maintain stable physical and chemical properties in high temperature environment, and will not age or deform due to long-term high temperature use. At the same time, the silicone rubber material also has good elasticity and sealing performance, which can tightly fit the surface of the first end cover, the second end cover and the heat exchange cylinder, effectively preventing water leakage. In addition, the silicone rubber material also has good corrosion resistance and wear resistance, which can resist the erosion of scale and impurities, maintain the cleanliness and efficient operation of the sealing ring.
