Description

Technical Field

[0001] This application relates to the field of ice maker technology, and more specifically, to a heat preservation device and a ball ice maker. Background Technology

[0002] Ice makers typically use a refrigerant circulation system. Through processes such as evaporation, compression, condensation, and expansion, heat is absorbed from water, lowering the water temperature and ultimately forming ice. The refrigeration system usually uses components such as a compressor, condenser, evaporator, and expansion valve.

[0003] In related technologies, after water forms an ice ball, the ice ball gradually melts while stored in an ice basket, and the ice ball gradually becomes a non-spherical shape, affecting its use. Utility Model Content

[0004] In order to at least solve the problem mentioned in the related technology that the ice puck will gradually melt during storage and affect its use, this application provides a heat preservation device and an ice maker for ice pucks.

[0005] To achieve the above objectives, this application provides a heat preservation device for keeping ice balls in a hockey ice maker warm. The heat preservation device includes a connecting member and a heat exchanger. The connecting member includes an inlet pipe, a first outlet pipe, and a second outlet pipe. The inlet pipe is connected to the outlet of a refrigeration unit, allowing a refrigerant medium to flow into the connecting member. The first outlet pipe passes through an ice-making unit and connects to the refrigeration unit for making ice balls. The second outlet pipe passes through an ice storage unit and connects to the refrigeration unit. The heat exchanger is disposed outside the ice storage unit and is capable of exchanging heat with the second outlet pipe and the ice storage unit.

[0006] Furthermore, multiple heat exchangers are provided along the outside of the ice storage element, and the multiple heat exchangers cover at least one side of the ice storage element.

[0007] Furthermore, the heat exchanger is at least partially in contact with the ice storage unit, and the heat exchanger is at least partially in contact with the second discharge pipe.

[0008] Furthermore, the heat exchanger is configured as a heat exchange pipe, which is connected to the second discharge pipe.

[0009] Furthermore, the heat exchange pipe is bent on the outer wall of the ice storage unit.

[0010] This application also provides a hockey ice maker, including an ice maker body and a heat preservation device as described in any of the above embodiments. A cooling component is disposed within the ice maker body, and the heat preservation device is used to keep the ice balls made by the ice maker body warm.

[0011] Furthermore, the refrigeration component includes a compressor, a condenser, and a filter. The compressor is connected to the condenser and the filter in sequence via pipes and is also connected to the feed pipe of the connecting component. A capillary tube is provided on the pipe between the filter and the connecting component.

[0012] Furthermore, the ice maker body includes an ice-making component, which includes a cold plate and a mold. The mold at least partially abuts against the cold plate, and the cold plate has a cold cavity communicating with the first discharge pipe.

[0013] Furthermore, the ice maker body includes a water tank filled with refrigerant liquid, and the water tank is located near the ice-making component and the ice-storing component.

[0014] Furthermore, the water tank includes a first water tank and a second water tank, the first water tank being located near the ice-making component, the second water tank being located near the ice-storing component, and the first water tank and the second water tank being connected by a circulation pump.

[0015] With the above technical solution, when using the insulation device of this application, the low-temperature refrigeration medium of the refrigeration component flows in from the feed pipe of the connecting component. Among them, part of the cooling medium flows out from the first discharge pipe to the ice-making component to make ice balls, and the other part of the cooling medium flows from the second discharge pipe to the heat exchange component to exchange heat with the heat exchange component, thereby reducing the temperature of the heat exchange component. The heat exchange component then exchanges heat with the ice storage component, thereby reducing the temperature of the ice storage component, thus preventing the temperature of the ice storage component from rising, and thus preventing the ice balls in the ice storage component from melting.

[0016] The insulation device of this application, through a connecting member, diverts a portion of the low-temperature cooling medium between the refrigeration component and the ice storage component for insulation of the ice storage component, preventing the temperature of the ice storage component from rising, effectively extending the storage time of the ice balls, and improving the storage effect of the ice balls.

[0024] This embodiment provides a heat preservation device to solve the problem in related technologies where ice balls in ice makers gradually melt during storage, affecting their use.

[0025] Please see Figure 1This embodiment provides a heat preservation device for keeping ice balls in a ball ice maker warm. The heat preservation device includes a connecting member 100 and a heat exchanger 200. The connecting member 100 includes an inlet pipe 110, a first outlet pipe 120, and a second outlet pipe 130. The inlet pipe 110 is connected to the outlet of the refrigeration unit 300 to allow the refrigerant to flow into the connecting member 100. The first outlet pipe 120 passes around the ice-making unit 400 and is connected to the refrigeration unit 300 for making ice balls. The second outlet pipe 130 passes around the ice storage unit 500 and is connected to the refrigeration unit 300. The heat exchanger 200 is disposed outside the ice storage unit 500 and can exchange heat with the second outlet pipe 130 and the ice storage unit 500.

[0026] Specifically, when the refrigeration system is operating normally, the generated low-temperature refrigeration medium flows into the connecting member 100 through the feed pipe 110. Inside the connecting member 100, the low-temperature refrigeration medium is automatically divided into two paths, one of which enters the first discharge pipe 120 and the other enters the second discharge pipe 130.

[0027] The low-temperature refrigerant flowing into the first discharge pipe 120 passes through the ice-making component 400. During this process, the refrigerant absorbs heat from the water inside the mold 420 and evaporates, causing the water to freeze into ice balls. After absorbing heat, the refrigerant returns to the refrigeration system for circulation.

[0028] The low-temperature refrigerant flowing into the second discharge pipe 130 passes around the ice storage element 500 and undergoes direct heat exchange with the heat exchange element 200. During this process, the low-temperature refrigerant absorbs heat from the heat exchange element 200, causing its temperature to drop rapidly. At the same time, the refrigerant itself releases heat, causing its temperature to rise.

[0029] The fully cooled heat exchanger 200 is in close contact with the outer wall of the ice storage unit 500. Heat conduction occurs between the heat exchanger 200 and the ice storage unit 500, transferring the low temperature to the shell of the ice storage unit 500. After the shell temperature of the ice storage unit 500 decreases, a low-temperature barrier is formed, effectively blocking the transfer of heat from the external environment to the internal ice ball. At the same time, the air inside the ice storage unit 500 is also cooled, further inhibiting the melting of the ice ball.

[0030] The refrigerant that has completed its heat release function flows out of the heat exchanger 200 and returns to the refrigeration system. The refrigeration system cools it again and sends it back into the connecting member 100 through the feed pipe 110 to begin a new round of diversion and cooling. As long as the ice maker is in normal working condition, the heat preservation cycle will continue to ensure that the ice storage unit 500 is always kept at a low temperature.

[0031] The insulation device in this embodiment does not require an additional compressor 310 or a complex independent refrigeration system. By adding a connecting component 100, it utilizes the excess cooling capacity generated by the main refrigeration system and distributes it through pipes to achieve insulation of the ice storage area. This method is low-cost, energy-efficient, and compact. It not only effectively prevents the ice balls from melting and maintains their shape, but also significantly extends the storage time of the ice balls.

[0032] In one embodiment, exemplarily, such as Figure 1 As shown, multiple heat exchangers 200 are arranged along the exterior of the ice storage container 500, and each heat exchanger 200 covers at least one side of the ice storage container 500. The ice storage container 500 is typically a three-dimensional container, and heat may enter from the top, sides, or bottom. A single heat exchanger 200 can only cool a localized area, easily leading to a phenomenon where the temperature is low near the heat exchanger 200 and high further away, resulting in "localized melting." In this embodiment, multiple heat exchangers 200 are distributed along the exterior of the ice storage container 500, which is equivalent to setting multiple cooling points on the container surface, improving the cooling effect.

[0033] At least one side is covered, meaning the heat exchanger 200 forms a continuous or semi-continuous cooling zone on the side wall of the ice storage unit 500. Cold energy is simultaneously conducted inward from multiple points, making the temperature of the entire side more uniform. Even if the ice pucks are stacked in different positions, a relatively uniform low-temperature environment can be obtained, preventing some ice pucks from melting prematurely due to uneven heating. This improves the consistency of ice puck quality and maintains the integrity of the overall shape.

[0034] The heat exchange capacity is directly proportional to the heat exchange area. Multiple heat exchange elements 200 increase the total heat exchange area in contact with the ice storage unit 500, multiplying the heat exchange area compared to a single heat exchange element 200. The ice storage unit 500 can cool to the target low temperature more quickly, shortening the pre-cooling time after equipment startup. Furthermore, when frequent ice removal leads to a large influx of hot air, multiple heat exchange elements 200 can more quickly remove the intruding heat, maintaining a stable temperature in the ice storage area.

[0035] Understandably, if a single heat exchanger 200 becomes loose or has poor contact, that area will completely lose cooling. Multiple heat exchangers 200 form a redundant design, so even if one heat exchanger 200 experiences poor contact due to vibration or aging, the other heat exchangers 200 can still maintain basic cooling functionality, resulting in high system reliability.

[0036] In one embodiment, exemplarily, such as Figure 1As shown, the heat exchanger 200 is at least partially in contact with the ice storage unit 500, and at least partially in contact with the second discharge pipe 130. Heat transfer efficiency is directly related to the contact area, the thermal conductivity of the material, and the contact thermal resistance. Contact implies direct solid-state heat conduction, which is one of the most efficient heat transfer methods. The contact between the heat exchanger 200 and the ice storage unit 500 minimizes contact thermal resistance, allowing cold energy to be transferred quickly and almost without loss from the heat exchanger 200 to the shell of the ice storage unit 500. The contact between the second discharge pipe 130 and the heat exchanger 200 ensures that the cold energy of the cryogenic refrigerant is efficiently transferred to the heat exchanger 200. This avoids "thermal barriers" caused by poor thermal conductivity media such as air gaps, resulting in minimal delay in cold energy transfer and a rapid response to temperature changes.

[0037] The cold energy transfer path is as follows: low-temperature refrigerant, second discharge pipe 130, heat exchanger 200, ice storage unit 500, and ice ball. Through physical contact, it is ensured that each link in the transfer chain is physically connected and has unobstructed heat conduction. This forms a series, low-resistance heat conduction path, improving the reliability of heat transfer in this embodiment.

[0038] In one embodiment, exemplarily, such as Figure 1 As shown, the heat exchanger 200 is configured as a heat exchange pipe, which is connected to the second discharge pipe 130. By directly configuring the heat exchanger 200 as a heat exchange pipe and connecting it to the second discharge pipe 130, the low-temperature refrigerant flows directly into the heat exchange pipe, which itself becomes the cold source, closely adhering to the outer wall of the ice storage unit 500. The cold energy transfer path changes, with the low-temperature refrigerant, heat exchange pipe, and ice storage unit 500 eliminating the thermal resistance between the second discharge pipe 130 and the heat exchanger 200, resulting in higher cold energy transfer efficiency. Furthermore, when the refrigerant flows within the heat exchange pipe, its temperature is the same as the cooling temperature obtained by the ice storage unit 500, with no intermediate losses, significantly increasing the amount of cold energy that can be transferred per unit time.

[0039] The thermal conductivity of solids is much lower than that of fluids through convection. The cryogenic refrigerant flows continuously within the heat exchange pipes, exchanging heat with the ice storage unit 500 via forced convection. Once the refrigeration system is started, the cooling capacity reaches the ice storage area with the fluid flow rate. In other words, after the equipment starts, the ice storage unit 500 can quickly begin to cool down and reach the target temperature even faster. Similarly, when frequent ice removal causes heat intrusion, the flowing refrigerant can quickly remove the heat, maintaining temperature stability and preventing temperature fluctuations.

[0040] In one embodiment, exemplarily, such as Figure 1As shown, the heat exchange pipes are curved on the outer wall of the ice storage unit 500. Within the limited surface area of ​​the outer wall of the ice storage unit 500, the length of straight pipes is limited, resulting in a small heat exchange area. By using curved designs, such as serpentine, spiral, or coiled shapes, the total length of the heat exchange pipes can be significantly extended without increasing the overall size of the equipment. The increase in pipe length is directly equivalent to a multiple increase in heat exchange area. This allows the heat exchange pipes to transfer more cooling energy to the ice storage unit 500 per unit time. The refrigerant releases its cooling energy more fully in the longer pipes, resulting in a higher outflow temperature and higher cooling energy utilization. Even with high ambient temperatures or frequent ice removal, the low temperature can be maintained, preventing the ice balls from melting.

[0041] This embodiment also provides a hockey ice maker, including an ice maker body and a heat preservation device as described in any of the above embodiments. A cooling component 300 is provided inside the ice maker body, and the heat preservation device is used to keep the ice balls made by the ice maker body warm.

[0042] The ice maker body is responsible for producing ice balls, the insulation device is responsible for preserving the ice balls, and the refrigeration unit 300 serves as a unified cold source, simultaneously contributing to ice making and insulation. This allows the ice balls produced in this embodiment to be preserved for a long time, making them convenient to use.

[0043] In one embodiment, exemplarily, such as Figure 1 As shown, the refrigeration component 300 includes a compressor 310, a condenser 320, and a filter 330. The compressor 310 is connected to the condenser 320 and the filter 330 in sequence via pipes, and is also connected to the feed pipe 110 of the connecting component 100. A capillary tube 340 is installed on the pipe between the filter 330 and the connecting component 100. The compressor 310 provides power to compress the gaseous refrigerant, increasing its pressure and temperature. The condenser 320 cools the high-temperature, high-pressure gaseous refrigerant, releasing heat into the environment and condensing it into a high-pressure liquid. The filter 330 purifies the high-pressure liquid refrigerant, removing moisture and impurities. The capillary tube 340 throttles and reduces the pressure of the high-pressure liquid refrigerant, turning it into a low-temperature, low-pressure gas-liquid mixture. The connecting component 100 and subsequent heat exchange pipes act as an evaporator, where the low-temperature, low-pressure refrigerant absorbs heat from the ice-making mold 420 and the ice storage unit 500, evaporates into a gaseous state, and then returns to the compressor 310. A standard four-step cycle of "compression, condensation, throttling, and evaporation" is formed to achieve efficient heat transfer.

[0044] It is worth mentioning that the capillary tube 340 is a copper tube with an extremely thin inner diameter and a relatively long length, which generates significant flow resistance to the high-pressure liquid refrigerant flowing through it. When the high-pressure liquid refrigerant flows through the capillary tube 340, its pressure drops sharply, and part of the liquid flashes and vaporizes, forming a low-temperature, low-pressure gas-liquid two-phase flow. This is a crucial step in the refrigeration cycle where the temperature drops rapidly, creating the necessary conditions for subsequent heat absorption in the connecting element 100. The inner diameter and length of the capillary tube 340 determine its fixed flow capacity, thereby controlling the amount of refrigerant flowing into the connecting element 100 per unit time and ensuring stable system operation under design conditions. During compressor 310 shutdown, the capillary tube 340 allows the refrigerant to flow slowly from the high-pressure side to the low-pressure side, allowing the system pressure to tend to balance, which is beneficial for easy start-up of compressor 310 next time, reducing starting torque and current surge.

[0045] In addition, it should be noted that in actual use, the refrigeration component 300 also needs to include other components such as an expansion valve and a power supply so that the compressor 310, condenser 320 and other components can form a complete cooling system. Any existing components can be used, as long as they can enable the refrigeration component 300 to work normally, and will not be described further here.

[0046] In one embodiment, exemplarily, such as Figure 1 As shown, the ice maker body includes an ice-making component 400, which includes a cold plate 410 and a mold 420. The mold 420 at least partially abuts against the cold plate 410, and the cold plate 410 has a cold cavity communicating with the first discharge pipe 120. The cold plate 410 and the mold 420 are at least partially abutted by means such as tight fitting, pressing, or thermally conductive adhesive bonding, achieving solid-state heat conduction between the mold 420 and the cold plate 410. The cold cavity inside the cold plate 410 is directly connected to the first discharge pipe 120, and the low-temperature refrigerant flows in the cold cavity, transferring the cold energy to the mold 420 through the metal wall of the cold plate 410. This eliminates poor heat-conducting media such as air gaps, resulting in a short cold energy transfer path and low resistance. This reduces energy loss during the transfer process and improves the system's energy efficiency ratio.

[0047] In one embodiment, exemplarily, such as Figure 1As shown, the ice maker body includes a water tank 600 filled with refrigerant. The water tank 600 is located near the ice-making component 400 and the ice storage component 500. Traditional direct cooling systems or simple indirect cooling systems produce pulsed cooling output, fluctuating drastically with the start and stop of the compressor 310, leading to unstable ice-making and ice-storage temperatures and affecting the quality of the ice balls. In this embodiment, the water tank 600 is equipped with sufficient water. As a cold energy storage component with a large heat capacity, the water tank 600 absorbs and stores cold energy during the ice ball making process while the compressor 310 is running, and continuously releases cold energy when the compressor 310 is off, providing a nearly constant low-temperature environment for the ice-making component 400 and the ice storage component 500. It is understood that the water tank 600 can also be filled with different liquids, such as water or liquid beverages, depending on the type of ice balls being made.

[0048] In addition, the system does not need to frequently start the compressor 310 to cope with small load changes, which extends the life of the compressor 310, reduces energy consumption and noise, and can also easily cope with the thermal shock caused by frequent ice removal or changes in ambient temperature.

[0049] As a cryogenic liquid container, water tank 600 experiences heat loss during both ice-making and heat preservation processes, resulting in a uniform temperature of the refrigerant liquid inside. The bottom or part of the structure of the ice-making component 400 and the ice storage component 500 can be immersed in or closely attached to the water tank 600. On one hand, the convective heat transfer efficiency between liquid and solid is far higher than that of air, leading to rapid heat transfer. On the other hand, natural convection of the liquid ensures a highly uniform temperature within the tank, guaranteeing consistent cooling across all parts of the ice-making component 400 and the ice storage component 500.

[0050] In one embodiment, exemplarily, such as Figure 1 As shown, the water tank 600 includes a first water tank 610 and a second water tank 620. The first water tank 610 is located near the ice-making component 400, and the second water tank 620 is located near the ice storage component 500. The first water tank 610 and the second water tank 620 are connected by a circulation pump. Ice making and ice storage have different temperature requirements. Ice making typically requires temperatures from -10°C to -20°C, or even lower, to achieve rapid freezing; ice storage requires low temperatures close to 0°C, such as -2°C to +2°C, to prevent the ice balls from melting. However, excessively low temperatures lead to energy waste and excessive frost buildup in the ice basket. In this embodiment, the first water tank 610 is dedicated to ice making and can maintain a lower set temperature. The second water tank 620 is dedicated to ice storage and can maintain a slightly higher, more energy-efficient set temperature. Each functional zone obtains the temperature most suitable for its process, avoiding "overcooling" or "undercooling". The ice storage zone does not need to maintain extremely low temperatures, significantly reducing energy consumption. The low temperature in the ice making zone ensures rapid freezing, while the appropriate low temperature in the ice storage zone prevents excessive frost formation and ice ball sticking.

[0051] A circulating pump drives the refrigerant to flow between two water tanks 600, achieving active transfer of cooling capacity. The flow rate and direction can be precisely adjusted by the control system. During the refrigeration process, the distribution of cooling capacity between the two water tanks 600 can be adjusted in real time according to the ice-making cycle and ice storage requirements. For example, during ice making, the first water tank 610 is cooled first; when the temperature in the ice storage area rises, the amount of cooling capacity flowing to the second water tank 620 is increased.

[0052] If one of the water tanks 600 or its cooling circuit fails, the circulating pump can transfer some of the cooling capacity from the other water tank 600 as an emergency backup, improving the system's fault tolerance. Alternatively, under specific operating conditions, the liquids in the two tanks can be mixed to quickly equalize the temperature, improving the applicability of this embodiment.

[0053] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
