Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] See Figure 1 , Figure 1 A schematic diagram of a rapid cooling system 100 according to an embodiment of this application is shown. The rapid cooling system 100 provided in an embodiment of this application includes a heat exchange unit 110 and a water inlet unit 120 and a water outlet unit 130 connected to the heat exchange unit 110.

[0027] The heat exchange unit 110 includes a cooling chamber 111 and a heat exchange tube 112 disposed within the cooling chamber 111. The cooling chamber 111 is used to receive inorganic salts. The two ends of the heat exchange tube 112 are respectively connected to the water inlet unit 120 and the water outlet unit 130, and the heat exchange tube 112 is used to transmit the water source input from the water inlet unit 120 to the water outlet unit 130. In a specific configuration, the heat exchange tube 112 has a spiral structure to ensure sufficient water storage and high heat exchange efficiency. The water outlet unit 130 includes a water outlet pipe 131, the two ends of which are respectively connected to the heat exchange tube 112 and the user's water outlet. The user's water outlet can be a faucet or a water valve to ensure water access for the user.

[0028] The water inlet unit 120 is also connected to the cooling chamber 111. The water inlet unit 120 is also used to transmit water to the cooling chamber 111. The inorganic salts in the cooling chamber 111 are used to dissolve in the water and absorb heat, thereby reducing the water temperature in the heat exchange tubes 112 within the cooling chamber 111. It should also be noted that the water used to dissolve the inorganic salts in the cooling chamber 111 is separate from the water in the heat exchange tubes 112 used by the user and is not interconnected, in order to reduce the contamination of drinking water by inorganic salts and ensure water safety.

[0029] The aforementioned rapid cooling system 100, by installing heat exchange tubes 112 and inorganic salts in the cooling chamber 111, and by providing water to the heat exchange tubes 112 and the cooling chamber 111 through a water inlet unit 120, serves two purposes: firstly, the water entering the heat exchange tubes 112 is delivered to the user end through the water outlet unit 130 for user access; secondly, the water entering the cooling chamber 111 dissolves the inorganic salts within the cooling chamber 111, causing the inorganic salts to rapidly dissolve and absorb heat to form a low-temperature solution. This low-temperature solution exchanges heat with the heat exchange tubes 112, thereby lowering the temperature of the water in the heat exchange tubes 112 and ensuring that the user can obtain the required cold water from the heat exchange tubes 112. Compared to current methods that rely on the cyclical operation of components such as compressors, condensers, and evaporators, or semiconductor refrigeration, this application offers a faster cooling response, lower energy consumption, and no operating noise, greatly satisfying the user's need for instant cold water.

[0030] In order to facilitate the water supply of the water inlet unit 120 to the cooling chamber 111 and the heat exchange tube 112, the water inlet unit 120 is specifically configured to include a water inlet 121 and a water inlet pipe 122 and a cooling pipe connected to the water inlet 121. The water inlet 121 is used to supply water, the end of the water inlet pipe 122 away from the water inlet 121 is connected to the heat exchange tube 112, and the end of the cooling pipe away from the water inlet 121 is connected to the cooling chamber 111.

[0031] With the above configuration, part of the water source input from the inlet 121 is fed into the heat exchange tube 112 through the inlet pipe 122, and the heat exchange tube 112 flows to the user end through the outlet unit 130 for user use; part of the water source is fed into the cooling chamber 111 through the cooling pipe to dissolve the inorganic salts in the cooling chamber 111. When the inorganic salts dissolve, they quickly absorb heat to form a low-temperature solution. The low-temperature solution exchanges heat with the heat exchange tube 112 to reduce the temperature of the water source in the heat exchange tube 112, ensuring that the user can obtain cold water from the heat exchange tube 112.

[0032] To meet market demands for energy conservation and environmental protection and to achieve the recycling of inorganic salts, in a preferred embodiment, the rapid cooling system 100 further includes a separation unit 140 and a recovery unit 150. The separation unit 140 is connected to the refrigeration chamber 111 and is used to receive the low-temperature solution and separate inorganic salts and water vapor from it. The separation unit 140 also transfers the inorganic salts to the refrigeration chamber 111. The recovery unit 150 is connected to both the separation unit 140 and the refrigeration chamber 111 and is used to receive water vapor, convert it into liquid water, and then transfer it to the refrigeration chamber 111.

[0033] The aforementioned rapid cooling system 100 separates inorganic salts and water vapor from the low-temperature solution using a separation unit 140. The separation unit 140 then transfers the inorganic salts back to the refrigeration chamber 111. A recovery unit 150 condenses the water vapor to form liquid water, which is then transferred back to the refrigeration chamber 111. This allows the liquid water to dissolve the inorganic salts again, forming a low-temperature solution. The low-temperature solution exchanges heat with the heat exchange tube 112, thus cooling the heat exchange tube 112. This enables the recycling of inorganic salts, meeting current energy-saving and environmental protection requirements.

[0034] To facilitate the separation of inorganic salts and water vapor from the cryogenic solution by the separation unit 140, the separation unit 140 specifically includes an evaporation chamber 141, a heating element 142, and a separation and transfer assembly 143. The separation and transfer assembly 143 connects the refrigeration chamber 111 and the evaporation chamber 141, and is used to transfer the cryogenic solution from the refrigeration chamber 111 to the evaporation chamber 141. In a specific configuration, the separation and transfer assembly 143 includes a separation and transfer pipe 1431, a separation pump 1432 mounted on the separation and transfer pipe 1431, and a separation solenoid valve 1433. The two ends of the separation and transfer pipe 1431 are connected to the refrigeration chamber 111 and the evaporation chamber 141, respectively. The transfer of the cryogenic solution from the refrigeration chamber 111 to the evaporation chamber 141 is achieved by controlling the operation of the separation pump 1432 and the separation solenoid valve 1433.

[0035] A heating element 142 is disposed within the evaporation chamber 141. The heating element 142 is used to heat the low-temperature solution, causing water vapor to form and inorganic salt crystals to precipitate. It should be noted that the heating element 142 can be any heating element 142, such as a heating tube, heating rod, or heating coil. These are all mature technologies and will not be elaborated upon further here. It is easy to understand that when the heating element 142 heats the low-temperature solution, the water in the solution evaporates, and the inorganic salts recrystallize due to saturation, thereby achieving the separation of inorganic salts and water vapor from the low-temperature solution.

[0036] To facilitate the transfer of solid inorganic salts back to the refrigeration chamber 111 by the separation unit 140, more specifically, the rapid cooling system 100 further includes a crystallization transfer channel and a movable plate 160 movably disposed at the crystallization transfer channel. The crystallization transfer channel connects the interior of the evaporation chamber 141 and the refrigeration chamber 111. The movement of the movable plate 160 is used to close or open the crystallization transfer channel. Through the above configuration, controlling the movement of the movable plate 160 can realize the transfer of inorganic salts from the evaporation chamber 141 to the refrigeration chamber 111.

[0037] In a specific configuration, the evaporation chamber 141 and the cooling chamber 111 can be separated by a cavity through a separation plate 170, forming an upper evaporation chamber 141 and a lower cooling chamber 111. A crystal transfer channel is opened in the separation plate 170 to connect the evaporation chamber 141 and the cooling chamber 111, so that the inorganic salt deposited at the bottom of the evaporation chamber 141 can be transferred to the cooling chamber 111 through the crystal transfer channel.

[0038] To facilitate the movement of the movable plate 160 for closing or opening the crystal transport channel, the movable plate 160 is rotatably mounted on the separation plate 170, and the movable plate 160 is located near the crystal transport channel. Rotating the movable plate 160 can either shield or expose the crystal transport channel. In specific configurations, the movable plate 160 can be rotatably connected to the separation plate 170 via hinges, pivots, or other methods.

[0039] To automatically control the flow of inorganic salts into the refrigeration chamber 111, the rapid cooling system 100 further includes a control unit, a rapid cooling drive unit 180 communicating with the control unit, and an interactive screen. The output of the rapid cooling drive unit 180 is connected to the movable plate 160. The interactive screen sends control signals according to user instructions. During operation, the user touches the commands on the interactive screen, which then generates control signals and sends them to the control unit.

[0040] The control unit drives the rapid cooling drive component 180 to move the movable plate 160 according to the control signal, so as to close or open the crystal transfer channel of the movable plate 160.

[0041] To facilitate the smooth flow of inorganic salt into the refrigeration chamber 111, two movable plates 160 are used. One side of each movable plate 160 is rotatably connected to the separation plate 170. The sides of the two movable plates 160 facing away from the separation plate 170 abut against each other and initially form a V-shape to ensure smooth transport of inorganic salt and prevent blockage. The specific working process of the movable plates 160 is as follows: Driven by the rapid cooling drive component 180, the two abutting sides of the two movable plates 160 move away from or closer to each other, thereby closing or opening the crystal transport channel, thus realizing the transport or interruption of inorganic salt.

[0042] It should also be noted that the evaporation chamber 141 is also provided with a feeding port that is opposite to the movable plate 160, so as to ensure that the inorganic salt used for the first time can smoothly enter the heat exchange chamber through the feeding port and the movable plate 160.

[0043] In order to facilitate the recycling unit 150 receiving water vapor and converting it into liquid water before transferring it to the cooling chamber 111, more specifically, in some embodiments, the recycling unit 150 includes a steam recycling chamber 151 and a circulation transmission assembly 152.

[0044] The steam recovery chamber 151 is connected to the evaporation chamber 141. The steam recovery chamber 151 is used to receive water vapor in the evaporation chamber 141. In a specific configuration, the recovery unit 150 also includes a steam transmission pipe 153. One end of the steam transmission pipe 153 is located in the steam recovery chamber 151, and the other end of the steam transmission pipe 153 is connected to the upper end of the evaporation chamber 141 so that the water vapor evaporated in the evaporation chamber 141 can be quickly input into the steam recovery chamber 151 through the steam transmission pipe 153.

[0045] The steam recovery chamber 151 is also connected to the water inlet unit 120, which is used to transfer water to the steam recovery chamber 151 to condense water vapor into liquid water. The circulation transmission component 152 connects the steam recovery chamber 151 and the cooling chamber 111, and is used to transfer the liquid water in the steam recovery chamber 151 to the cooling chamber 111.

[0046] As described above, the water inlet unit 120 includes a water inlet 121 and a water inlet pipe 122 connected to the water inlet 121. The end of the water inlet pipe 122 away from the water inlet 121 is connected to the heat exchange pipe 112. To facilitate the input of water into the steam recovery chamber 151 for condensing water vapor into liquid water, the water inlet unit 120 also includes a water supply pipe 123 connected to the water inlet 121. The end of the water supply pipe 123 away from the water inlet 121 is connected to the steam recovery chamber 151. In a specific configuration, the water supply pipe 123 is also equipped with a water supply pump 125 and a water supply solenoid valve 124. By controlling the operation of the water supply pump 125 and the water supply solenoid valve 124, the water supply pipe 123 inputs water into the steam recovery chamber 151 for condensing water vapor.

[0047] It should be noted that, in order to optimize the structure, the water supply pipe 123 can replace the refrigeration pipe. The water source entering the steam recovery chamber 151 through the water supply pipe 123 can be transferred to the refrigeration chamber 111 by the circulation transmission component 152, thereby dissolving the inorganic salts in the refrigeration chamber 111.

[0048] To facilitate the transfer of liquid water from the steam recovery chamber 151 to the refrigeration chamber 111 via the circulation transfer assembly 152, the circulation transfer assembly 152 includes a circulation transfer pipe 1521 and a circulation pump 1522 and a circulation solenoid valve 1523 mounted on the circulation transfer pipe 1521. The two ends of the circulation transfer pipe 1521 are connected to the steam recovery chamber 151 and the refrigeration chamber 111, respectively. By controlling the operation of the circulation pump 1522 and the circulation solenoid valve 1523, the liquid water from the steam recovery chamber 151 is transferred to the refrigeration chamber 111.

[0049] To accelerate the condensation and liquefaction of water vapor in the steam recovery chamber 151, the recovery unit 150 further includes a heat dissipation device 154 disposed in the steam recovery chamber 151. In a specific configuration, the heat dissipation device 154 is located at the top of the steam recovery chamber 151. The heat dissipation device 154 can be a fan, a blower, heat dissipation fins, or a heat dissipation system composed of a water-cooled plate, circulation pipes, a water pump, and a radiator. The aforementioned heat dissipation components are all mature technologies and will not be elaborated upon here.

[0050] Combination Figure 2 As shown, this application also provides a water purification device 10, which includes the rapid cooling system 100 described in any of the above embodiments. In a specific configuration, the water purification device 10 further includes a raw water pipe 200 and a filtration system 300 connected to each other. The raw water pipe 200 is used to transport municipal tap water, and the filtration system 300 is connected to the water inlet unit 120 in the rapid cooling system 100. The filtration system 300 is used to filter the tap water flowing into the raw water pipe 200 to form filtered water that is injected into the water inlet 121 of the water inlet unit 120.

[0051] To ensure the filtration effect of the filtration system 300, the filtration system 300 includes a pre-filtration unit 310 and a reverse osmosis filtration unit 320 connected to each other. The pre-filtration unit 310 is connected to the raw water pipe 200 and is used to filter large particulate impurities in the tap water before conveying it to the reverse osmosis filtration unit 320. The outlet of the reverse osmosis filtration unit 320 is connected to the inlet 121 of the rapid cooling system 100. The reverse osmosis filtration unit 320 is used to further filter impurities to obtain high-purity filtered water, which is then conveyed to the rapid cooling system 100. In specific settings, the pre-filtration unit 310 can be a filter screen, activated carbon filter, or similar structure, and the reverse osmosis filtration unit 320 can be an RO membrane module. A booster pump 330 and a filter solenoid valve 340 can be installed between the pre-filtration unit 310 and the reverse osmosis filtration unit 320 to transfer the pre-filtered water from the pre-filtration unit 310 to the reverse osmosis filtration unit 320 for further filtration as needed.

[0052] It should also be noted that the water purification device 10 of this application is also used to provide room temperature water and hot water. Therefore, the water purification device 10 also includes a room temperature water outlet pipe 400 and a heating system 500. The two ends of the room temperature water outlet pipe 400 are respectively connected to the user water outlet 600 and the water outlet of the reverse osmosis filter unit 320. A room temperature solenoid valve 410 is installed on the room temperature water outlet pipe 400 to ensure that the user can take room temperature water as needed. The heating system 500 is connected to the user water outlet 600 and the water outlet of the reverse osmosis filter unit 320. The heating system 500 is used to heat the filtered water transmitted by the reverse osmosis filter unit 320 and then transmit it to the user water outlet 600 so that the user can obtain hot water. The heating system 500 is a mature technology and will not be described in detail here.

[0053] To facilitate the discharge of the filtered wastewater from the filtration system 300, the filtration system 300 also includes a wastewater pipe 700 installed on the reverse osmosis filtration unit 320. A wastewater solenoid valve 710 is installed on the wastewater pipe 700 to ensure that the user discharges wastewater as needed.

[0054] It should also be emphasized that, in order to ensure that the low-temperature solution formed by the inorganic salt can exchange heat with the heat exchange tube 112 and reduce the temperature of the water source in the heat exchange tube 112 to the required cold water temperature for the user, this application provides a cooling calculation as an example. For instance, sodium nitrate (NaNO3) is used as the inorganic salt. It should be noted that the inorganic salt is not limited to sodium nitrate, but can be ammonium chloride, potassium nitrate, and many other types of inorganic salts.

[0055] The specific process is as follows: The mass m of sodium nitrate added to the refrigeration chamber 111 is obtained by weighing. NaNO3 For example, investing m NaNO3 For 200 g, based on the molar mass of sodium nitrate: M NaNO3 =85g / mol; to calculate the amount of sodium nitrate: n NaNO3 =m NaNO3 / M NaNO3 = 200g / 85 g / mol≈2.353 mol; 500ml of water is introduced into the cooling chamber 111. Based on the density of water being 1g / mL, the mass of the introduced water is m. water It weighs 500g; Based on the enthalpy of solubility of sodium nitrate: ΔH NaNO3 = +20.5 kJ / mol; and the amount of sodium nitrate, i.e., n NaNO3 To calculate the total heat Q absorbed during the dissolution of sodium nitrate. abs : Q abs =n NaNO3 *ΔH NaNO3 =2.353mol*20.5kJ / mol≈48.24kJ=48240J; The total heat absorbed by sodium nitrate, Q abs Also, the heat Q released by the water ext Q ext =m water *c water *ΔT, where: c water Since the specific heat capacity of water is also a constant, c water The value is 4.18 J / (g·°C), where ΔT is the change in temperature of the water source from the initial temperature to the second temperature after heat release. The second temperature also refers to the temperature of the low-temperature solution formed after the water source dissolves sodium nitrate. For example: when 500g of water is introduced to dissolve sodium nitrate, according to ΔT = Qext / (m NaNO3 *c water = 48240 J / (500 g * 4.18 J / (g·°C))≈23.1°C, meaning that under ideal adiabatic conditions, the complete dissolution of 200g of sodium nitrate in 500ml of water can lower the water temperature by approximately 23.1°C. For example, if the initial temperature of the water source is room temperature (25°C), theoretically, the temperature of the low-temperature solution formed after dissolving sodium nitrate in the water can be reduced to nearly 2 degrees Celsius. This cooling effect is sufficient to ensure that the low-temperature solution can exchange heat with heat exchange tube 112, thereby lowering the water temperature in heat exchange tube 112 to the user's required cold water temperature, meeting practical usage requirements.

[0056] It should also be emphasized that, due to heat exchange losses in the rapid cooling system 100, the actual temperature reduction range of the dissolved sodium nitrate water source is between 18 and 22 degrees Celsius, which can still meet the user's need for rapid cooling water. It should also be noted that the decomposition temperature of sodium nitrate is approximately 380 degrees Celsius, while the evaporation temperature of water is 100 degrees Celsius. When the low-temperature solution containing sodium nitrate is circulated to the evaporation chamber 141 for evaporation, the safety margin is large, which is beneficial to the normal operation of the heating element 142.

[0057] Based on this, this application also provides a cooling method for the rapid cooling system 100 described in any of the above embodiments, wherein the water inlet unit 120 includes a refrigeration pipe connected to the refrigeration chamber 111, and a refrigeration valve and a flow meter are installed on the refrigeration pipe, and the cooling method includes: Calculate the heat Q absorbed by the inorganic salt of mass m1 when it dissolves according to the first equation, where the first equation is: Q = (m1 / M) / (m1 / M) 无机盐 )*ΔH 焓 M 无机盐 ΔH is the molar mass of the inorganic salt. 焓 The enthalpy of dissolution of inorganic salts is used to transport inorganic salts with a mass of m1 to the refrigeration chamber 111 through the feeding port and crystal transfer channel during specific operation. The mass m2 of water required to flow into the refrigeration chamber 111 when the water source for dissolving inorganic salts is cooled from its initial temperature to the preset temperature is calculated based on the second equation. The second equation is: m2 = Q / (c water * ΔT), c water ΔT is the specific heat capacity of water, and ΔT is the difference between the initial temperature and the preset temperature. The initial temperature can be obtained by measuring the temperature of the water source before the inorganic salt is dissolved. For example, the water source temperature is measured at the inlet 121. The preset temperature is the temperature of the low-temperature solution to be formed after the sodium nitrate is dissolved in the water source. The first water flow value F required to supply water to the cooling chamber 111 is calculated using a third-party program, where the third-party program is: F = m² / ρ 水 , ρ 水 The density of water; Flow meter 1524 is used to detect the second water flow value entering the refrigeration chamber 111 through the refrigeration pipe; The opening and closing of the refrigeration valve is controlled based on the second water flow value and the first water flow value. In specific operation, the refrigeration valve is opened after the first water flow value is known, and the refrigeration valve is closed when the second water flow value is equal to the first water flow value.

[0058] With the above configuration, this application controls the first water flow value input to the refrigeration chamber 111 by opening and closing the refrigeration valve to adjust the temperature of the low-temperature solution in the refrigeration chamber 111, thereby adjusting the water temperature in the heat exchange tube 112 that exchanges heat with the low-temperature solution. In one embodiment, the refrigeration pipe and refrigeration valve are omitted. Water is input from the steam recovery chamber 151 to the refrigeration chamber 111 by controlling the start of the circulation pump 1522 and the circulation solenoid valve 1523. The flow meter 1524 on the circulation pipe controls the closing of the circulation pump 1522 and the circulation solenoid valve 1523. When the water in the steam recovery chamber 151 is insufficient, water can be added to the steam recovery chamber 151 by starting the water replenishment pump 125 and the water replenishment solenoid valve 124.

[0059] It should also be noted that this application can intelligently regulate the flow rate of water entering the cooling chamber 111. A temperature sensor is set at the water inlet 121 to obtain the initial temperature of the water source. By communicating with the temperature sensor, the circulating pump 1522, the circulating solenoid valve 1523, the flow meter 1524 and the control unit, the user inputs the specific type of inorganic salt, the input mass m1 and the preset temperature through the interactive screen. The control unit calculates the first water flow value of the water source to be introduced into the cooling chamber 111 according to the first equation, the second equation and the third-party program. The first water flow value controls the start of the circulating pump 1522 and the circulating solenoid valve 1523. When the second water flow value fed back by the flow meter 1524 is equal to the first water flow value, the circulating pump 1522 and the circulating solenoid valve 1523 are turned off.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
