[0002] Supercooled water is water that remains liquid even though its temperature is below its freezing point (0°C). It is a metastable form of water and is widely used in many industries.

[0003] The heat exchanger is a core component for producing supercooled water. It has a first fluid channel for a low-temperature cooling medium and a second fluid channel for water.

DETAILED DESCRIPTION

[0033] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0034] In the various drawings of the present application, certain dimensions of structures or portions can be exaggerated relative to other structures or portions for purposes of illustration, and thus, are used merely to illustrate the basic structure of the subject matter of the present application.

[0035] As shown in the drawings, the present application provides a condensation-proof heat exchanger 100 and a super-cooled water preparation system having the same. Figures 1-12

[0036] The heat exchanger 100 of the present application comprises a shell 1 and a heat exchange core 2. The shell 1 provides an environment cavity for the heat exchange core 2, avoiding the influence of external environment temperature on the heat exchange core 2, preventing condensation, and ensuring the stability and durability of heat exchange.

[0037] The heat exchange core 2 comprises a plurality of first fluid channels, a plurality of second fluid channels, a first liquid inlet pipe 21 and a first liquid outlet pipe 22 communicating with the first fluid channels, and a second liquid inlet pipe 23 and a second liquid outlet pipe 24 communicating with the second fluid channels. The first fluid channels are used for circulating low-temperature cold-carrying medium, and the second fluid channels are used for circulating water. Heat exchange between the cold-carrying medium and the water in the heat exchange core 2 enables the water to obtain cold energy and form super-cooled water.

[0038] In an embodiment, the heat exchange core 2 comprises first fluid channel sheets and second fluid channel sheets arranged alternately. The first surface of the first fluid channel sheet has a concave first heat exchange area, and the second surface is a plane. The first surface of the second fluid channel sheet has a concave second heat exchange area, and the second surface is a plane. The first fluid channel is formed between the first surface of the first fluid channel sheet and the second surface of the second fluid channel sheet. The second fluid channel is formed between the first surface of the second fluid channel sheet and the second surface of the first fluid channel sheet.

[0039] The thickness of the first heat exchange area and the second heat exchange area is not greater than 0.1 mm, the thickness of the regions of the first fluid channel sheet and the second fluid channel sheet except the heat exchange areas is not greater than 0.2 mm, and the length of the first fluid channel sheet and the second fluid channel sheet in the fluid channel extension direction is not greater than 50 mm. The fluid channels with small cross-sectional area and short length can improve the heat exchange between the water and the low-temperature cold-carrying medium, and the water flow can pass through the second fluid channel in a very short time, which can greatly reduce the probability of ice blockage in the heat exchange core 2. The shell 1 comprises a containing cavity 11 for containing the heat exchange core 2, a first inlet 12 through which the first liquid inlet pipe 21 passes, a first outlet 13 through which the first liquid outlet pipe 22 passes, a second inlet 14 through which the second liquid inlet pipe 23 passes, and a second outlet 15 through which the second liquid outlet pipe 24 passes.

[0040] ​That is, the shell 1 is a heat preservation shell, for example, made of a material with good heat preservation performance, used to isolate the heat exchange core 2 from the external environment, reduce the influence of the external environment temperature on the heat exchanger, and reduce the risk of condensation.

[0041] The first liquid outlet pipe 22 is flush with the first outlet 13 of the heat exchange core 2, that is, the end of the first liquid outlet pipe 22 is in the same plane as the first outlet 13 of the shell 1, neither protruding nor recessing. This design prevents condensate from flowing into the subcooled water along the first liquid outlet pipe 22, reduces the risk of crystallization of the subcooled water caused by external interference, thereby avoiding ice blockage and improving system stability.

[0042] In some embodiments, the distance between the first outlet 13 and the heat exchange core 2 is greater than the distance between the first inlet 12 and the heat exchange core 2. And / or, 0-2 / 3 of the first liquid inlet pipe 21 is located in the containing cavity, and the first liquid outlet pipe 14 is entirely located in the containing cavity. And / or, the length of the first liquid inlet pipe 21 is 40 mm ± 5 mm, and the length of the first liquid outlet pipe 22 is 60 mm ± 5 mm.

[0043] In this way, the first outlet 13 is at a longer distance from the heat exchange core 2, which can avoid the condensation phenomenon caused by the low-temperature first liquid outlet pipe 14 at the first outlet of the shell 1, further reducing the risk of crystallization and ice blockage at the outlet of the subcooled water.

[0044] The length of the first liquid inlet pipe 21, the first liquid outlet pipe 22, and the assembly mode with the shell 1, especially the length in the containing cavity 11, can better prevent condensation.

[0045] In some embodiments, the end of the first liquid inlet pipe 21 away from the heat exchange core 2, the end of the second liquid inlet pipe 23 away from the heat exchange core 2, and the end of the second liquid outlet pipe 24 away from the heat exchange core 2 all extend out of the shell 1, facilitating connection with external pipelines.

[0046] Preferably, the size of the end of the first liquid inlet pipe 21 away from the heat exchange core 2, the end of the second liquid inlet pipe 23 away from the heat exchange core 2, and the end of the second liquid outlet pipe 24 away from the heat exchange core 2 extending out of the shell 1 is 2 mm-8 mm. Maintaining an appropriate extension length meets the connection requirements and does not expose too much to the external environment, so as not to affect the temperature inside the shell 1 through heat conduction.

[0047] In an actual application, the installation length extending out of the shell 1 is 5 mm ± 1.5 mm, which ensures the convenience of installation with external pipelines, and no extra pipelines are exposed outside the shell 1, improving or maintaining the excellent heat preservation performance of the entire heat exchanger 100.

[0048] In some embodiments, the first liquid inlet pipe 21, the second liquid inlet pipe 23, and the second liquid outlet pipe 24 are each provided with a threaded connection at one end away from the heat exchange core 2, and the threaded connection is located on the outside of the housing 1. The threaded connection design provides a standardized connection method, facilitating installation and removal while ensuring a tight connection to prevent water and cold leakage.

[0049] The anti-condensation heat exchanger 100 of the present invention also includes a temperature measurement assembly 3. This assembly includes a probe 31 for detecting temperature, located within the accommodating chamber 11. This assembly can detect the outlet water temperature in real time, providing the system with accurate temperature monitoring data. When temperature anomalies occur, this assembly can prompt the system to take timely action to prevent ice blockage or expedite its removal.

[0050] In the present invention, the detection head 31 is in contact with the first liquid outlet pipe 22 to detect the temperature of the supercooled water passing through the first liquid outlet pipe 22 in real time.

[0051] In some embodiments, the probe 31 is tangent to the inner surface of the first liquid outlet pipe 22. "Tangent" means that the probe 31 matches the inner surface of the first liquid outlet pipe 22, the probe 31 is coplanar with the inner surface of the first liquid outlet pipe 22, and the probe 31 does not protrude into the liquid flow area.

[0052] During installation, ensure that the probe 31 (e.g., the tip of the temperature sensor probe) installed on the outlet side of the heat exchanger is tangent to the first outlet pipe 22. If the probe 31 is installed too deep, extending into the area of ​​the first outlet pipe 22 where the supercooled water flows, the probability of ice blockage increases. This is because a probe 31 that is too deep provides an impact surface, generating a small energy disturbance that can cause the supercooled water to break free of its supercooled state and crystallize. Designing the probe 31 to be tangent to the inner surface of the first outlet pipe 22 allows for accurate water temperature measurement without disrupting water flow, reducing the probability of supercooled water crystallization.

[0053] In some embodiments, the probe 31 is embedded in the wall of the first liquid outlet pipe 22. The design of embedding the probe 31 in the wall can avoid direct contact with the water flow and reduce the risk of water crystallization caused by the probe protruding into the pipe.

[0054] In some embodiments, the probe head 31 contacts the outer surface of the first liquid outlet pipe 22. The design of the probe head 31 contacting the outer surface can quickly respond to temperature changes without disturbing the internal fluid.

[0055] The anti-condensation heat exchanger 100 of the present invention further includes a heating component 4. The heating component 4 includes a heating structure 41. The heating structure 41 is located in the accommodating cavity 11 to provide heat to the heat exchange core 2 or the accommodating cavity 11.

[0056] The heating component 4 can provide heat to the heat exchange core 2 or the housing chamber 11 when needed. For example, in the event of ice blockage, the heating component 4 raises the temperature by 2°C-10°C, effectively shortening the thawing time and accelerating the restoration of normal system operation. For example, in the event of condensation, the heating component 4 raises the temperature to or above the dew point, preventing the transfer of cold energy from the heat exchange core 2 to the surface of the housing 1, thereby preventing condensation on the anti-condensation surface of the heat exchanger 100.

[0057] Furthermore, the first fluid channels and the second fluid channels are alternately arranged along a first direction, and the temperature increasing structure 41 is in contact with the heat exchange core 2 , specifically, in contact with both side surfaces of the heat exchange core 2 along the first direction.

[0058] In one embodiment, the temperature-raising structure is located on both side surfaces of the heat exchange core 2 along the first direction. Specifically, the temperature-raising structure 41 is sheet-shaped, has a high degree of adhesion to the surface, and heats up quickly. The "first direction" here refers to the main direction in which the fluid channels are arranged. In actual applications, the sheet-shaped temperature-raising structure 41 is attached to the surface of the heat exchanger to shorten the thawing time by raising the temperature by 2°C-10°C when ice blockage occurs. The structure in which the first fluid channel and the second fluid channel are alternately arranged along the first direction improves the heat exchange efficiency; the design in which the sheet-shaped temperature-raising structure is located on both side surfaces of the heat exchange core 2 makes the temperature rise more uniform and comprehensive, can provide heat more effectively, and shortens the thawing time.

[0059] In some embodiments, the anti-condensation heat exchanger 100 further includes an integrated design of a temperature measuring component 3 and a temperature increasing component 4 .

[0060] The temperature measurement assembly 3 includes a probe 31 for detecting temperature and a first cable 32 electrically connected to the probe 31. The probe 31 is located within the accommodating chamber 11 and in contact with the first liquid outlet pipe 22. The specific configuration of the probe 31 is as described above. The end of the first cable 32, away from the probe 31, is located outside the housing 1.

[0061] The heating assembly 4 includes a heating structure 41 and a second cable 42 electrically connected to the heating structure 41. The structure and configuration of the heating structure 41 are as described above. One end of the second cable 42, away from the heating structure 41, is located outside the housing 1.

[0062] The housing 1 is provided with a first through-hole 16 for passing both the first cable 32 and the second cable 42. The design of routing the cables of the temperature measuring component 3 and the heating component 4 through the same through-hole 16 simplifies the structure of the housing 1, reduces the number of openings, reduces the risk of condensation and cold leakage, and facilitates centralized control and maintenance.

[0063] It should be noted that the heating structure 41 of the present invention is an electric heating structure. In embodiments where the second cable 42 is not provided, the heating structure 41 is a heating structure with its own battery. In embodiments where the second cable 42 is provided to power the heating structure 41, the heating structure 41 may or may not be equipped with a battery.

[0064] Through the above-mentioned structural design, the anti-condensation heat exchanger 100 of the present invention can effectively reduce the condensation phenomenon on the surface of the heat exchanger, prevent supercooled water crystallization and ice blockage, and even if ice blockage occurs, it can be quickly resolved, thereby improving the operating efficiency and stability of the supercooled water preparation system.

[0065] In some other embodiments of the present invention, a vacuum cavity is formed between the heat exchange core 2 and the housing 1. The vacuum cavity design effectively isolates the heat exchange between the heat exchange core 2 and the external environment, and prevents condensation on the surface.

[0066] In some other embodiments of the present invention, the anti-condensation heat exchanger 100 also includes an atmosphere-conditioning component, which includes an air pump and an air pipe connected to the air pump. The air pump is a vacuum pump or an air supply pump, and the air pipe is connected to the accommodating cavity 11 through a second through hole 17 on the shell 1.

[0067] The controlled atmosphere assembly further ensures that condensation does not form inside the heat exchanger housing 1 by using a vacuum pump to evacuate the interior, fundamentally solving the condensation problem. In practice, a vacuum pump interface is provided on the sidewall of the housing 1 to evacuate the interior. This vacuum environment effectively prevents moisture in the air from condensing into droplets on low-temperature surfaces, thus avoiding a series of problems caused by condensation.

[0068] The gas conditioning unit can also deliver dry air via an air pump. This dry air effectively isolates internal and external heat exchange, preventing condensation. In the event of ice blockage, dry air at a temperature slightly above the freezing point of water (e.g., 1°C-10°C) can be delivered to promptly relieve ice blockage.

[0069] The present invention further provides a supercooled water preparation system, comprising a cooling system, a water supply system, and the anti-condensation heat exchanger 100 of any one of the above-mentioned embodiments.

[0070] The cooling system includes a first temperature control device that provides a cooling medium at a first preset temperature and a first pump that controls the flow of the cooling medium. The first preset temperature is below the freezing point of water. The cooling system that provides a cooling medium at a low temperature is also referred to as a low-temperature system.

[0071] The water supply system includes a second temperature control device for providing water at a second preset temperature and a second pump for controlling the water flow rate. The second preset temperature is higher than the freezing point of water, and the temperature difference between the second preset temperature and the freezing point of water is no more than 10°C.

[0072] The flow rates of the cooling medium and water are set as needed. Typically, the flow rate of the cooling medium is greater than the flow rate of the water. In some embodiments, the flow rate of the cooling medium is 1 L / min to 10 L / min, or 1.1 L / min to 2 L / min, or 1.2 L / min to 1.8 L / min. The flow rate of water is 0.5 L / min to 5 L / min, or 0.6 L / min to 2 L / min, or 0.8 L / min to 1.2 L / min.

[0073] The cooling medium and water exchange heat in the heat exchanger 100 to form supercooled water. Specifically, the first liquid inlet pipe 21 is connected to the water supply system, and the second liquid inlet pipe 23 and the second liquid outlet pipe 24 are both connected to the cooling system.

[0074] The design of the entire supercooled water preparation system enables sufficient heat exchange between the cooling medium and water in the heat exchanger, achieving a supercooled state in which the water temperature is below 0°C but still remains in liquid form; at the same time, through the application of the anti-condensation heat exchanger 100, the problems of supercooled water crystallization and ice blockage caused by condensation on the surface of the heat exchanger are avoided, thereby improving the ice-making efficiency and stability of the entire system.

[0075] In some embodiments, the cooling system provides a cooling medium below the freezing point of water (0°C) to the heat exchanger, reducing the water temperature to produce supercooled water. The water supply system provides constant-temperature water close to the freezing point to ensure the stability of the incoming water. The synergistic effect of the cooling and water supply systems ensures that the water flow within the heat exchanger quickly and evenly reaches the target temperature range.

[0076] The present invention will be further described below with reference to specific embodiments.

[0077] Example 1: Anti-condensation heat exchanger The anti-condensation heat exchanger 100 includes a heat exchange core 2 and a heat-insulating shell 1 .

[0078] The heat exchange core 2 is made of stainless steel and includes multiple sets of first and second fluid channels arranged alternately along a first direction. The first fluid channels are for circulating the cooling medium and are connected to a first liquid inlet pipe 21 and a first liquid outlet pipe 22. The second fluid channels are for circulating water and are connected to a second liquid inlet pipe 23 and a second liquid outlet pipe 24.

[0079] The insulated housing 1 is made of materials such as polyurethane and has excellent thermal insulation properties. It has an internal accommodating cavity 11 for mounting the heat exchange core 2. The housing 1 is provided with a first inlet 12, a first outlet 13, a second inlet 14, and a second outlet 15, through which a first liquid inlet pipe 21, a first liquid outlet pipe 22, a second liquid inlet pipe 23, and a second liquid outlet pipe 24 pass, respectively.

[0080] In this embodiment, the end of the first liquid outlet pipe 22 distal from the heat exchange core 2 is flush with the first outlet 13, while the first liquid inlet pipe 21, the second liquid inlet pipe 23, and the second liquid outlet pipe 24 all extend 1-5 mm from the housing. The distance between the first outlet 13 and the heat exchange core 2 is 50 mm, which is greater than the 30 mm distance between the first inlet 12 and the heat exchange core 2. This design provides better insulation at the outlet and effectively prevents crystallization of supercooled water due to condensation at the outlet. Tests have shown that this design effectively suppresses condensation on the heat exchanger surface and reduces the probability of ice blockage.

[0081] Example 2: Anti-condensation heat exchanger with heating and temperature measurement functions Based on Example 1, a temperature measurement component 3 and a heating component 4 are added. The temperature measurement component 3 includes a PT100 temperature sensor as a probe 31. Probe 31 is installed tangentially to the inner surface of the first liquid outlet pipe 22 to ensure that probe 31 does not protrude into the liquid flow area, thereby preventing supercooled water crystallization caused by the probe protruding. A first cable 32 of the temperature measurement component 3 is led out through the first through-hole 16 in the housing 1 and connected to the temperature control system.

[0082] The heating assembly 4 consists of two rectangular heating structures 41, one attached to each side of the heat exchange core 2 along the fluid channel alignment. The heating power of these sheet-like heating structures is designed to be 200W, allowing the surface temperature of the heat exchange core 2 to deviate from the crystallization temperature when needed. The second cable 42 of the heating assembly 4 and the first cable 32 of the temperature measurement assembly 3 are routed through the same first through-hole 16 and connected to the temperature control system, enabling coordinated temperature monitoring and control.

[0083] Test results show that when ice blockage occurs, activating the heating function can shorten the thawing time from the traditional 30-40 minutes to 5-15 minutes, significantly improving system recovery speed. Furthermore, the real-time monitoring function of the temperature measurement component 3 provides early warning of temperature anomalies, further reducing the risk of ice blockage.

[0084] Example 3: Anti-condensation heat exchanger with gas conditioning function and supercooled water preparation system Based on Examples 1 or 2, a controlled atmosphere assembly is added. This assembly includes a small vacuum pump and an air pipe connecting the vacuum pump to the housing 1. The air pipe communicates with the accommodating chamber 11 through a second through hole 17 at the rear of the housing 1. The vacuum pump can evacuate the interior of the accommodating chamber 11 to a vacuum state, controlling the pressure within the range of 5-10 Pa.

[0085] The anti-condensation heat exchanger 100 is integrated into a complete supercooled water preparation system. The cooling system includes a first temperature control device capable of providing a cooling medium at temperatures of -15°C or below, and a first pump with a flow rate of 1.2L / min-1.8L / min. The water supply system includes a second temperature control device capable of providing water at 2-8°C, and a second pump with a flow rate of 0.8L / min-1.2L / min. The system connects to the water supply system via a first inlet pipe 21 and to the cooling system via a second inlet pipe 23 and a second outlet pipe 24, forming a complete ice-making cycle.

[0086] System operation tests have shown that, under ambient conditions of 25°C and 60% relative humidity, the system can stably produce supercooled water at temperatures between -5°C and -8°C, and operate continuously for 72 hours without condensation or ice blockage. Even in the event of artificial ice blockage, the system can resume normal operation within 15 minutes, demonstrating excellent performance and stability.

[0087] In summary, the condensation-resistant heat exchanger 100 provided by the present invention, through the synergistic effects of the housing 1 design, temperature measurement component 3, heating component 4, and gas conditioning assembly, effectively solves the problems of crystallization and ice blockage caused by condensation on the heat exchanger surface during the supercooled water preparation process, significantly improving the operating efficiency and stability of the system. The technical solution of the present invention is not only applicable to supercooled water preparation systems but can also be extended to other applications requiring low-temperature heat exchangers, thus possessing broad application prospects.
