[0036] Please refer to Figure 1 , Figure 1is a water path structure diagram of a first embodiment of a water purification heat exchange system provided by the present application. The present application provides a water purification heat exchange system, which comprises a heat exchange module 10 and a heating module 20, the heating module 20 is connected with the heat exchange module 10, and / or; the heating module 20 is connected to at least one of the water inlet and the water outlet of the heat exchange module 10, that is, it can be understood that, optionally, the heating module 20 is connected to the water outlet of the heat exchange module 10, as shown in Figure 1 , the water path s is connected with the water inlet of the heat exchange module 10, and the water path s is heat exchanged through the heat exchange module 20; the heating module 20 is arranged at the water outlet of the heat exchange module 10, and the heating module 20 supplements heat to the purified water of the water outlet. Optionally, the heating module 20 is connected to the water inlet of the heat exchange module 10, as shown in Figure 2 , the water path s is connected with the water inlet of the heat exchange module 10, and the water path s is heat exchanged through the heat exchange module 20, and the heating module 20 is connected with the water inlet of the heat exchange module 10, used for preheating the water source of the water inlet, and then heat-exchanging the heated water source through the heat exchange module 10 to realize secondary heating of the water source; the water source will enter the heating module 20 after passing through the heat exchange module 10. The heating module 20 supplements heat to the purified water of the water outlet, that is, the main function of the heating module 20 is to improve the temperature of the purified water, which can be through electric heating, gas heating or other heating methods. As known from the above, the heat exchange module 10 is responsible for preliminary temperature regulation, such as reducing the initial temperature of the purified water. The heating module 20 is responsible for further regulating the temperature after the heat exchange module 10 to ensure that the purified water reaches the required final temperature; optionally, the heating module 20 is connected to the water inlet and the water outlet of the heat exchange module 10, as shown in Figure 3 , the water source of the water inlet is preheated through the heating module 20, and then the heated water source is heat-exchanged through the heat exchange module 10 to realize secondary heating of the water source, and then the heating module 20 heats the secondary heated water source to realize rapid heating of the water source to the target temperature.

[0037] Optionally, in some embodiments of the present application, a heat exchange medium and an energy storage assembly are provided within the heat exchange module 10, and the energy storage assembly exchanges heat with the water path s through the heat exchange medium. The heat exchange medium is a substance used to transfer heat between the energy storage assembly and the water path. This can be water, antifreeze, oil, or other liquid with good thermal conductivity. The energy storage assembly is responsible for storing thermal energy, usually storing energy when the system is not running or the load is low, and releasing energy when the demand is high. The energy storage assembly can be phase change materials (PCMs), which change state (such as from solid to liquid) when absorbing or releasing heat, or other types of heat storage technology, such as thermal storage tanks. The heat exchange medium circulates between the energy storage assembly and the water path, absorbing heat in the energy storage assembly and transferring it to the clean water, or vice versa, absorbing heat from the clean water and storing it in the energy storage assembly. By using the energy storage assembly, the system can store energy when the demand for electricity is low or the cost is low, thereby reducing energy waste and reducing operating costs.

[0038] Please continue to read Figures 1 to 3 Optionally, in some embodiments of the present application, when the temperature of the heat exchange module 10 is lower than the first threshold value, the heating module 20 heats the heat exchange module 10, and / or the heating module 20 heats the water source in the water inlet and / or water outlet of the heat exchange module 10.

[0039] Optionally, in some embodiments of the present application, when the upper limit of the energy storage temperature of the heat exchange module 10 is lower than the second threshold value, the heating module 20 heats the water source in the water inlet and / or water outlet of the heat exchange module 10.

[0040] Optionally, in some embodiments of the present application, when the temperature of the water source in the water outlet of the heat exchange module 10 is less than the set outlet water temperature, the heating module 20 heats the water source in the water outlet of the heat exchange module 10.

[0041] Optionally, in some embodiments of the present application, please read Figure 4The heat exchange module 10 can specifically include a first heat exchange sub-module 101, a second heat exchange sub-module 102, and a compressor 103. The water path s is connected to the water inlet of the first heat exchange sub-module 101 and the water inlet of the second heat exchange sub-module 102, respectively. The water path s is cooled by the first heat exchange sub-module 101, and the water path s is heated by the second heat exchange sub-module 102. The compressor 103 is connected to the first heat exchange sub-module 101 and the second heat exchange sub-module 102. The main function of the first heat exchange sub-module 101 is to cool the incoming purified water. The first heat exchange sub-module 101 can use a cooling medium (such as refrigerant or cold phase change material) to absorb the heat of the purified water, thereby reducing the temperature of the purified water. The second heat exchange sub-module 102 corresponds to the first heat exchange sub-module 101, and the main function of the second heat exchange sub-module 102 is to heat the purified water. The second heat exchange sub-module 102 can use a heating medium (such as hot water, steam, or hot phase change material) to transfer heat to the purified water, thereby increasing the temperature of the purified water. The compressor 103 is used to increase the pressure of the refrigerant or other medium, thereby achieving the transfer of heat between the first heat exchange sub-module 101 and the second heat exchange sub-module 102. The compressor 103 plays a role in circulating and adjusting the pressure of the refrigerant in the purified water heat exchange system to ensure the effectiveness of the heat exchange process. The water path s is a channel connecting various modules, and the water path s leads the purified water to the first heat exchange sub-module 101 and the second heat exchange sub-module 102, respectively. For example, when a user needs to prepare cold water, the first heat exchange module 101 can be used to cool the water source in the water path s, thereby meeting the user's demand for preparing cold water. For example, when a user needs to prepare hot water, the second heat exchange module 102 can be used to cool the water source in the water path s, thereby meeting the user's demand for preparing hot water. For example, when a user needs to prepare warm water, the first heat exchange module 101 can be used to cool the water source in the water path s to obtain cold water, and at the same time, the second heat exchange module 102 can be used to heat the water source in the water path s to obtain hot water. Finally, the purified water heat exchange system mixes the cold water and the hot water in a certain proportion to prepare warm water.

[0042] Optionally, in some embodiments of the present application, referring to Figure 5 The water path s is provided with a first valve assembly 301 and a second valve assembly 302. The first valve assembly 301 is arranged at the first end of the water path s, and the second valve assembly 302 is arranged at the second end of the water path s and between the first heat exchange sub-module 101 and the second heat exchange sub-module 102.

[0043] It can be understood that in the purified water heat exchange system, the valve assemblies play a crucial role in controlling the direction and flow of water flow to achieve precise temperature control and system management.

[0044] The first valve assembly 301 is used to control the flow of clean water into the first heat exchange sub-module 101 and the second heat exchange sub-module 102, such as controlling whether the water source flows through the first heat exchange sub-module 101 or the second heat exchange sub-module 102. Of course, in some cases, when the user needs normal temperature water, the first valve assembly 301 can also control the flow of clean water into the first heat exchange sub-module 101 and the second heat exchange sub-module 102. The second valve assembly 302 is used to control the flow direction of clean water after being cooled by the first heat exchange sub-module 101, and to control the flow direction of clean water after being cooled by the second heat exchange sub-module 101, to determine whether the water flow is directed to other parts of the system, such as controlling the mixing of cold water and hot water to prepare normal temperature water. In addition, the second valve assembly 302 can also adjust the water flow speed of the first heat exchange sub-module 101 and the second heat exchange sub-module 102 to adapt to different water usage requirements. When the system is maintained or fails, the second valve assembly 302 can be used to shut off the water flow to protect the system from further damage. The first valve assembly 301 and the second valve assembly 302 can support the system to operate in different modes, such as cold water only mode, hot water only mode or mixed temperature water mode.

[0045] Optionally, in some embodiments of the present application, as shown in Figure 6 A water pump 40 is provided on the water path s, which is provided on the second end of the water path s, and the water pump pressurizes the water source of the water path s. When the system is started or shut down, the water pump 40 can prevent water hammer phenomenon and reduce the impact on the pipeline and equipment.

[0046] Optionally, in some embodiments of the present application, please refer to Figure 7 The heating module 20 includes a heating assembly 201, which is provided on the water path s and connected with the second heat exchange sub-module 102. The heating module 201 is responsible for further heating the clean water after passing through the second heat exchange module 102 to achieve the required hot water temperature. Specifically, the heating assembly 201 can use an electric heater, a gas heater or other types of heating elements to heat the clean water flowing through it, which can include one or more heating units to adapt to different flow and temperature requirements. Optionally, the heating module 20 can also include a temperature sensor and a controller to monitor and adjust the output of the heating assembly 201 to ensure that the clean water reaches the required temperature.

[0047] Optionally, in some embodiments of the present application, the heating assembly 201 is a special-shaped heating assembly, and the shape of the water inlet pipeline corresponding to the heating assembly 201 is adapted to the heating assembly 201. The special-shaped design increases the area of the heating surface, thereby improving the heat exchange efficiency, making the heating process faster and more energy-saving. The shape of the heating assembly 201 is adapted to the shape of the water inlet pipeline, which helps to improve the uniformity of water flow distribution and ensures that the water flow can fully contact the heating surface when passing through the heating assembly 201. The special-shaped design can include a streamlined design, a fin design, and a spiral design. Optionally, in some embodiments of the present application, the heating assembly 201 is a spiral design, as shown in Figure 8 The heating pipe is usually made of a metal pipe, which can be empty inside or filled with a heating medium such as an electric heating wire or steam. The electric heating pipe: an electric heating element is installed inside, and heat is generated by passing an electric current through the electric heating wire. The steam heating pipe: heat is transferred to the water or other medium flowing outside the pipe by the flow of steam in the pipe.

[0048] Optionally, in some embodiments of the present application, please refer to Figure 9 The heating module 20 can also include a backflow assembly 202 connected to the second heat exchange sub-module 102 through a backflow pipeline d. The backflow assembly 202 is used to backflow the water heated by the second heat exchange sub-module 102, achieving secondary heating of the water source, avoiding the target temperature not being reached by single heating, and thereby improving the user experience.

[0049] Optionally, in some embodiments of the present application, please refer to Figure 9 The backflow assembly 202 includes a backflow valve 202a and a backflow pump 202b, and the backflow valve 202a and the backflow pump are connected to the second heat exchange sub-module 202 through the backflow pipeline d.

[0050] The backflow valve 202a is commonly used to control the direction and flow of water in the backflow pipeline, preventing water from flowing backward. When the system starts or stops, the backflow valve can prevent hot water from flowing back to the cold water pipeline, avoiding mixing to cause unstable temperature. The backflow pump 202b draws the heated water from a certain part of the system back and sends it into the second heat exchange sub-module 102 again. By circulating hot water, the backflow pump 202b can improve the heat efficiency of the system and reduce the energy consumption required for heating. The backflow pipeline d connects the backflow valve 202a and the backflow pump 202b to the second heat exchange sub-module 102, forming a closed circulation path.

[0051] The above is the water purification heat exchange system provided by the present application.
