An embedded ice maker

Abstract

The present invention discloses an embedded ice maker, which relates to the technical field of energy-saving ice making. It includes an ice-making machine body, and a refrigeration module is installed inside the ice-making machine body. A heat-cold circulation mechanism is arranged on the inner side wall of the ice-making machine body. The heat-cold circulation mechanism is used to correspondingly absorb the hot air and cold air generated during the operation of the refrigeration module, and then recycle and utilize them. The inside of the fin is designed to be a hollow shape and is sleeved with a branch pipe, so that the water flow conveyed by the water delivery module can flow inside the branch pipe, forming a heat conduction group inside the fin. Since water has a large latent heat of vaporization, in the formed heat pipe structure, when one end of the heat pipe contacts the high-temperature area inside the side wall of the ice maker, the water absorbs heat and quickly evaporates into water vapor. Due to the flow characteristics of water vapor, it will move towards the cooling end of the heat pipe. At the cooling end, the water vapor condenses into liquid water again when it meets the cold. This heat pipe heat dissipation mechanism based on water effectively conducts the heat inside the side wall of the ice maker and dissipates it to the outside.

Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving ice-making, and particularly to an embedded ice maker. Background Art

[0002] Existing ice makers are electrical appliances specifically designed for making ice. Their design purpose is to be embedded in cabinets, kitchens, cupboards, and bars, integrating with the surrounding environment. While saving space, they can also provide users with a convenient ice-making function.

[0003] In the Chinese patent with the patent publication number CN207778903U, a refrigerator is disclosed, including: a refrigerating chamber, a refrigerating chamber door body, an ice maker cooling box, an air inlet duct, and an air return duct. The outer wall of the refrigerating chamber is covered with an outer shell, and an opening is formed in the rear wall of the outer shell. A recess is formed on the outer side of the rear wall of the refrigerating chamber opposite to the opening and recesses inward. The ice maker cooling box is arranged through the opening in the recess. An ice-making evaporator and a fan for blowing cold air around the ice-making evaporator are arranged in the ice maker cooling box. An ice-making chamber is formed on the inner side of the refrigerating chamber door body, and an ice maker is arranged in the ice-making chamber. The air inlet duct is configured to receive the cold air blown by the fan and guide it to the ice maker, and the air return duct is configured to guide the air exchanged heat with the ice maker to the area where the ice-making evaporator is located, so that the air exchanged heat with the ice maker is cooled by the ice-making evaporator and then guided to the ice maker through the air inlet duct.

[0004] However, the existing technology still has the following defects in specific use: 1. Compared with the equipment involved in the existing technology, a recess is formed at the position on the outer side of the rear wall of the refrigerating chamber opposite to the opening, the ice maker cooling box is arranged through the opening in the recess, and the ice-making evaporator is located in the ice maker cooling box, avoiding the influence of the cold air flow around the ice-making evaporator on the interior of the refrigerating chamber. Moreover, by setting an independent ice-making evaporator, more cold air is provided for the ice maker, improving the ice-making efficiency of the ice maker. However, when the ice-making evaporator is located in a relatively closed recess, air convection is greatly restricted. Normally, when the evaporator releases heat, the surrounding air will absorb the heat and take away the heat through natural convection or fan assistance. However, in the recess, the flow space of the air is narrow, and it is difficult to form effective convection. This reduction in heat dissipation efficiency will cause the ice-making evaporator to take longer to release heat during the defrosting process. Because the heat cannot be dissipated in time, the temperature around the ice-making evaporator will continue to rise, making the defrosting process slow, and thus affecting the working cycle of the entire ice maker.

[0005] 2. Compared with the prior art, after the ice maker is horizontally embedded in the cabinet body for installation, since the two side walls of the ice maker are closely attached to the cabinet body, it is difficult for air to flow around the two side walls, thus restricting the heat dissipation capacity of the two side walls. Therefore, only the bottom and the rear side wall can be relied on for heat dissipation ventilation. However, since the two side walls cannot dissipate heat effectively, this reduces the heat dissipation area of the ice maker. According to the principle of heat conduction, the smaller the heat dissipation area, under the same heat dissipation conditions, such as the same ambient temperature and air flow speed, the slower the heat dissipation speed will be. Furthermore, this will lead to the accumulation of heat inside the ice maker, causing the refrigeration system to consume more energy to maintain a low-temperature environment for ice making. Moreover, in order to maintain the normal ice-making temperature inside the ice maker, the refrigeration system needs to work continuously at a high intensity, which results in an increase in energy consumption. Compared with ice makers used in other scenarios, this type of embedded ice maker will consume 20% to 50% more electric energy. In the long run, it will increase the user's electricity cost.

[0006] Therefore, in view of this, the present invention proposes an embedded ice maker to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0007] To solve the above technical problems, the present invention provides an embedded ice maker to solve the technical problems proposed in the above background art.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is: an embedded ice maker, including an ice-making cabinet body, a refrigeration module is installed inside the ice-making cabinet body, and a heat-cold circulation mechanism is arranged on the inner side wall of the ice-making cabinet body. The heat-cold circulation mechanism is used to correspondingly absorb the hot air and cold air generated during the operation of the refrigeration module, and then recycle them.

[0009] Further, the heat-cold circulation mechanism includes a central shaft cylinder rotatably connected to the inner side wall of the ice-making cabinet body. Threaded screw shafts are symmetrically installed inside the central shaft cylinder. Nut sleeves are symmetrically installed on the outer walls of the threaded screw shafts. Collection bins are symmetrically communicated on both sides of the central shaft cylinder.

[0010] Further, the inside of the central shaft cylinder is symmetrically divided into upper and lower two regions, and discharge ports are symmetrically arranged on the outer wall of the central shaft cylinder.

[0011] Further, adsorption plates are symmetrically installed on the inner side walls of the collection bins. Adsorption openings are evenly formed on the surfaces of the adsorption plates, and the entire adsorption plates are made of activated carbon materials.

[0012] Further, the central shaft cylinder is rotatably connected to the threaded screw shafts, and miniature motors are externally connected to the end positions of the threaded screw shafts.

[0013] Further, the threaded screw shaft is in threaded connection with the nut collar, a ball screw structure is formed between the threaded screw shaft and the nut collar, and the nut collar is initially located at the central position on the outer wall of the threaded screw shaft.

[0014] Further, the middle shaft cylinder and the collection bin are kept in communication through a discharge port. The collection bin is trapezoidal as a whole, and one end of the collection bin close to the middle shaft cylinder is narrow, while the end of the collection bin far from the middle shaft cylinder is wide.

[0015] Further, a water delivery module is installed inside the refrigerator body. Water cooling heat dissipation mechanisms are symmetrically arranged outside the water delivery module. The water cooling heat dissipation mechanisms are used to circulate the water flow in the water delivery module to guide heat dissipation for the side walls of the refrigerator body. The water cooling heat dissipation mechanisms include connecting pipes symmetrically communicated with the outside of the water delivery module. Branch pipes are communicated with the outside of each connecting pipe, and fin groups are installed on the outside of each branch pipe.

[0016] Further, the outer wall of the fin group is composed of no less than three arc-shaped fins, and the inside of each arc-shaped fin is in a hollow shape.

[0017] Further, no less than four branch pipes are communicated with the outside of the connecting pipe. No less than three inclined columns are arranged on the outside of each branch pipe. A sliding connection is formed between the branch pipe and the fin group through the inclined columns and the arc-shaped fins.

[0018] Further, the water delivery module mainly includes a water delivery pipeline, a water pump and a recovery bin. The input end of the connecting pipe is communicated with the water delivery pipeline in the water delivery module, and the output end of the connecting pipe is communicated with the recovery bin in the water delivery module.

[0019] Further, an ice making module is installed inside the refrigerator body. The ice making module mainly includes an ice making evaporator and an ice making mold, and the ice making mold is closely attached above the ice making evaporator. The refrigeration module mainly includes a compressor, a condenser and an expansion valve, and the refrigeration module is communicated with the ice making evaporator in the ice making module.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In order to improve the ice-making efficiency and ice-deicing rate in the prior art, the present device introduces a thermal and cold cycle mechanism, so that a suction force is formed inside the central shaft cylinder during the ice-making process, and then hot air and cold air are continuously absorbed from near the condenser and the ice-making evaporator respectively, thereby maintaining stable working temperature environments for the ice-making evaporator and the condenser respectively, enabling the ice-making evaporator to absorb heat for refrigeration more efficiently, thus accelerating the ice-making speed. From the perspective of heat transfer, this method reduces the mixing of hot and cold gases around the evaporator and the condenser, and by timely sucking away the hot air around the evaporator and the cold air around the condenser, it increases the temperature difference between the evaporator and the object to be refrigerated, thereby accelerating the heat transfer speed and improving the ice-making efficiency.

[0021] Secondly, when the device is in the ice-deicing state, the collection bin rotates, and the reset movement of the threaded shaft is coordinated to generate a thrust force inside the central shaft cylinder. At this time, the heat collected from the condenser during the ice-making process is discharged in the direction corresponding to the ice-making evaporator, creating a preheating environment for ice-deicing of the ice-making module. This is equivalent to providing an additional heat source for the evaporator, accelerating the melting speed of the ice on the surface of the ice-making module. At the same time, the cold air previously collected at the ice-making evaporator is repositioned and discharged corresponding to the condenser, creating a cooling environment for the condenser, which helps to maintain the normal working state of the condenser during the ice-deicing process. And according to the law of conservation of energy, during the ice-deicing process, part of the heat released by the evaporator is used to melt the ice, and part needs to be dissipated into the surrounding environment. In the present device, it can ensure that the condenser part remains at a low temperature, which is conducive to the dissipation of the heat of the evaporator, thereby accelerating the ice-deicing process.

[0022] Compared with the ice-making methods in the prior art, the ice-making efficiency improved by the present device can produce more ice cubes per unit time, meeting the user's demand for a large number of ice cubes in a short time. At the same time, the ice-deicing rate is accelerated, which can shorten the entire ice-making cycle, improve the working efficiency of the ice-making machine, ensure that the user can obtain the next batch of ice cubes faster, and improve the user experience.

[0023] Moreover, through the air exhaust method of the present device, the natural discharge of gas from the inside of the device to the outside is realized. Compared with the prior art using a fan, the present device eliminates the problem of noise generated by the fan. For the usage scenario of the device, reducing noise can improve the comfort of life, so that the ice-making machine will not cause noise pollution to the home environment during operation. For commercial places, noise reduction can also improve customer satisfaction and provide a quieter environment for customers.

[0024] Among them, during the entire ice-making and ice-deicing cycle, this device realizes the recovery and reuse of heat and cold, enabling the hot and cold gases collected during the ice-making process to be redirected and redistributed during the ice-deicing process, reducing the need for additional energy input. Optimizing energy utilization helps reduce the energy consumption of the ice maker, meeting the requirements of modern energy conservation and environmental protection. Moreover, for places where ice makers are used on a large scale, such as large catering enterprises and hotels, it can significantly reduce the operating costs.

[0025] Among them, the directional absorption and discharge of hot and cold gases both contribute to maintaining the temperature stability of each component inside the device. A stable thermal environment helps extend the service life of each component inside the ice maker, reducing component damage and failures caused by temperature fluctuations. This can not only reduce the maintenance costs of the ice maker but also improve the reliability and stability of the device. Especially for ice makers operating continuously for a long time, this advantage is more obvious.

[0026] Among them, this device introduces adsorption plates on the inner sidewall of the collection bin, which can ensure that the gases absorbed from the condenser and evaporator come into full contact with the adsorption plates during the flow process, thereby effectively filtering out tiny particles such as dust and impurities in the gases and preventing them from entering other key internal components of the ice maker. Additionally, through the adsorption effect of the adsorption plates, it can also ensure that the produced ice cubes are odorless, so that when used in beverages and other foods, it will not damage the original taste of the drinks and improve the overall quality of the food.

[0027] To improve the heat dissipation problem of the sidewall of the embedded device, this device introduces a fin group, changing the surface contact between the device sidewall and the cabinet body to multiple point contacts, effectively increasing the heat dissipation area of the ice maker sidewall. According to the principle of heat conduction, the larger the heat dissipation area, the faster the heat dissipation speed under the same heat dissipation conditions. And the length of the fin group itself ensures the heat dissipation space between the cabinet body and the ice maker sidewall, enabling air to flow between the fin groups, further enhancing the heat dissipation effect, reducing the heat accumulation inside the ice maker, and lowering the energy required for the refrigeration system to maintain a low-temperature environment. In addition, the introduction of the fin group also provides better protection when the ice maker is horizontally embedded in the cabinet body. Through the fin group, it can prevent excessive friction between the ice maker sidewall and the cabinet body, reducing damage and wear caused by friction.

[0028] Compared with the prior art, the water-cooled heat dissipation structure introduced by this device according to the principle of heat conduction makes it easier to maintain the internal temperature of the device within the appropriate ice-making temperature range, without the need for the refrigeration system to cool excessively. This enables the ice maker to consume significantly less electrical energy under the same ice-making task. Compared with the previous embedded ice makers, it can effectively reduce the power consumption and greatly relieve the user's electricity cost.

[0029] Particularly importantly, the interior of the fin is designed in a hollowed-out form and sleeved with the branch pipe, enabling the water flow conveyed by the water delivery module to flow inside the branch pipe and form a heat conduction group inside the fin. Since water has a large latent heat of vaporization, in the formed heat pipe structure, when one end of the heat pipe contacts the high-temperature area inside the side wall of the ice maker, the water absorbs heat and quickly evaporates into water vapor. Due to the flow characteristics of water vapor, it will move towards the cooling end of the heat pipe. At the cooling end, the water vapor condenses back into liquid water when it meets the cold, releasing heat, and the heat is then dissipated to the external environment through the fin group. This water-based heat pipe heat dissipation mechanism effectively conducts the heat inside the side wall of the ice maker and dissipates it to the outside, further enhancing the heat dissipation capacity of the side wall of the ice maker.

[0030] The above-mentioned introduction of water flow and its recycling using the water delivery module also has the following advantages: First, by introducing the water flow into the branch pipe and realizing the continuous injection of the water flow with the help of the water delivery module, it can ensure that there is always fresh water flow for heat dissipation in the heat pipe structure formed inside the fin group. This helps to maintain the heat dissipation effect of the water medium and prevent the reduction of heat dissipation efficiency due to overheating of the water flow.

[0031] Second, the output end of the connecting pipe is kept connected to the recycling bin in the water delivery module, which means that the water flow used during the ice making process can be recycled and reused. This design of recycling not only saves water resources but also reduces the discharge of waste water, meeting the requirements of environmental protection and sustainable development.

[0032] Third, the continuous injection and recycling of the water flow help to keep the temperature and flow rate of the water flow in the heat pipe stable, thereby improving the heat conduction efficiency. This means that under the same heat dissipation conditions, the recycled water flow can dissipate the heat generated inside the ice maker faster, reducing the energy consumption of the refrigeration system. Moreover, through the continuous injection and recycling of the water flow, the impurities and sediments in the water flow in the heat pipe can be reduced, keeping the heat pipe clean and unobstructed, and reducing the failures and maintenance costs caused by blockage or corrosion of the introduced structure.

[0033] Fourth, by combining the introduced structure with the water delivery module in the existing equipment and using the water delivery module to realize the injection and recycling of the water flow, the design of the structure and the subsequent maintenance process can be simplified.

Detailed implementation manners

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0047] It should be noted that the structures and working principles of the above-mentioned refrigerator body 1, water delivery module 11, ice-making module 12, refrigeration module 13 and other devices belong to the prior art and will not be elaborated here.

[0048] Embodiment 1: Please refer to Figures 1 to 3 As shown, an embedded ice maker includes a refrigerator body 1. A refrigeration module 13 is installed inside the refrigerator body 1. A thermal and cold cycle mechanism 2 is provided on the inner side wall of the refrigerator body 1. The thermal and cold cycle mechanism 2 is used to correspondingly absorb the hot air and cold air generated during the operation of the refrigeration module 13 and subsequent recycle and utilization thereof.

[0049] It should be noted that the water delivery module 11 mainly includes a water delivery pipe, a water pump, and a recovery bin. The input end of the connecting pipe 31 is in communication with the water delivery pipe in the water delivery module 11, and the output end of the connecting pipe 31 is in communication with the recovery bin in the water delivery module 11. An ice making module 12 is installed inside the ice making box body 1. The ice making module 12 mainly includes an ice making evaporator and an ice making mold, and the ice making mold is closely attached above the ice making evaporator. The refrigeration module 13 mainly includes a compressor, a condenser, and an expansion valve, and the refrigeration module 13 is in communication with the ice making evaporator in the ice making module 12.

[0050] Specifically, during the ice making process, first, the compressor in the refrigeration module 13 compresses the refrigerant into a high-pressure gas, increasing its temperature and pressure. Then, the high-temperature and high-pressure refrigerant gas releases heat in the condenser and turns into a high-pressure liquid. When the high-pressure liquid passes through the expansion valve, the high-pressure liquid refrigerant reduces pressure and partially turns into a low-temperature and low-pressure gas-liquid two-phase object. When it reaches the ice making evaporator in the ice making module 12, the refrigerant absorbs the heat from the surrounding environment and turns into a low-temperature and low-pressure gas again, achieving refrigeration and ice making. During the ice making process, since heat is released around the condenser, the temperature around the condenser is relatively high. And the ice making evaporator absorbs the surrounding heat to cool down the ice making module installed on the side wall and cause ice condensation. Subsequently, when defrosting is carried out after ice making is completed, the ice making evaporator changes its working state. Specifically, during the ice making process, the ice making evaporator is a component that absorbs heat to freeze water. During the defrosting process, the working mode of the ice making evaporator changes. At this time, the ice making evaporator starts to release heat because after ice making is completed, the ice adheres to the ice making module, and it is necessary to heat the ice making module to make the ice fall off. At this time, the heat released by the ice making evaporator can increase the temperature of the ice making module, thus achieving defrosting.

[0051] Please refer to Figures 3 to 8 As shown, the heat and cold cycle mechanism 2 includes a central shaft cylinder 21 rotatably connected to the inner side wall of the ice making box body 1. Symmetrically installed inside the central shaft cylinder 21 are threaded screw shafts 22. Symmetrically installed on the outer walls of the threaded screw shafts 22 are nut sleeves 23. Symmetrically communicated on both sides of the central shaft cylinder 21 are collection bins 25.

[0052] It should be noted that the interior of the central shaft cylinder 21 is symmetrically divided into upper and lower regions, and discharge ports are symmetrically arranged on the outer wall of the central shaft cylinder 21. The central shaft cylinder 21 is rotatably connected to the threaded shaft 22. Miniature motors are externally connected to the end positions of the threaded shaft 22. The threaded shaft 22 is threadedly connected to the nut sleeve 23. A ball screw structure is formed between the threaded shaft 22 and the nut sleeve 23. And the nut sleeve 23 is initially located at the central position on the outer wall of the threaded shaft 22. The central shaft cylinder 21 is kept in communication with the collection bin 25 through the discharge ports. The collection bin 25 is trapezoidal as a whole, and the end of the collection bin 25 close to the central shaft cylinder 21 is narrow, while the end of the collection bin 25 far from the central shaft cylinder 21 is wide.

[0053] Specifically, during the ice-making process, the miniature motors externally connected to the end positions of the threaded shaft 22 will control it to rotate. Since the structure between the threaded shaft 22 and the nut sleeve 23 is similar to a ball screw structure, and the pitch of the outer wall of the threaded shaft 22 is equal to the inner diameter of the nut sleeve 23. At the same time, the tangent of the thread on the outer wall of the threaded shaft 22 and the cylinder to the horizontal plane is greater than 45 degrees. Therefore, when the threaded shaft 22 rotates, its own rotational force will continuously squeeze the nut sleeve 23 through the thread on the outer wall, and then smoothly transfer the rotational force to the nut sleeve 23, driving it to move linearly inside the central shaft cylinder 21. During the process of the nut sleeve 23 moving from the middle position to the end position inside the central shaft cylinder 21, the space inside the central shaft cylinder 21 gradually becomes larger, and at this time, the air pressure inside the central shaft cylinder 21 is less than the air pressure outside the central shaft cylinder 21, thereby generating a suction force inside the central shaft cylinder 21. And this suction force will act on the ice-making evaporator and the condenser parts respectively through the upper and lower collection bins 25, and then absorb the gas generated during the operation of the two parts into the collection bin 25, so as to maintain a stable working temperature environment for the ice-making evaporator and the condenser respectively, enabling the ice-making evaporator to absorb heat and refrigerate more efficiently, thereby accelerating the ice-making speed. From the perspective of heat transfer, this method reduces the mixing of hot and cold gases around the ice-making evaporator and the condenser, and by promptly sucking away the hot gas around the ice-making evaporator and the cold gas around the condenser, it increases the temperature difference between the ice-making evaporator and the object to be refrigerated, thereby accelerating the heat transfer speed and improving the ice-making efficiency.

[0054] Moreover, during the defrosting process, the entire collection bin 25 is driven to rotate by an external controller, so that the collection bin 25 initially corresponding to the ice-making evaporator is switched to correspond to the condenser, and the collection bin 25 initially corresponding to the condenser is switched to correspond to the ice-making evaporator. At this time, with the continuous rotation of the threaded shaft 22, the nut sleeve 23 starts to move back to its original position, that is, it moves from the end position inside the central shaft cylinder 21 towards the central position. During this process, the space inside the central shaft cylinder 21 gradually becomes smaller, and at this time, the air pressure inside the central shaft cylinder 21 is greater than the air pressure outside the central shaft cylinder 21, thereby generating a thrust inside the central shaft cylinder 21. With the formation of the thrust, it will be transmitted to the inside of the collection bin 25, and then the gas collected during the ice-making process is discharged. At this time, the heat collected from the condenser part during the ice-making process is discharged in the direction of the ice-making evaporator, creating a preheating environment for defrosting the ice-making module. This is equivalent to providing an additional heat source for the evaporator, accelerating the melting speed of the ice on the surface of the ice-making module on the side wall of the ice-making evaporator. At the same time, the cold air previously collected at the ice-making evaporator part is positionally switched and discharged corresponding to the condenser, creating a cooling environment for the condenser, which helps to maintain the normal working state of the condenser during the defrosting process.

[0055] It should be noted that adsorption plates 24 are symmetrically installed on the inner side walls of the collection bin 25. The surfaces of the adsorption plates 24 are evenly provided with adsorption openings, and the entire adsorption plate 24 is made of activated carbon material.

[0056] Specifically, when the gas enters the inside of the collection bin 25, it can ensure that the gas absorbed from the condenser and the ice-making evaporator comes into contact with the adsorption plate 24 during the flow process, thereby effectively filtering out tiny particles such as dust and impurities in the gas and preventing them from entering other key components inside the equipment. Moreover, through the adsorption effect of the adsorption plate 24, it can also ensure that the made ice has no peculiar smell. Thus, when used for beverages and other foods, it will not damage the original taste of the beverage and improve the overall quality of the food.

[0057] Example 2: On the basis of Example 1, please refer to Figures 9 to 11 As shown, a water delivery module 11 is installed inside the ice-making refrigerator body 1. Water-cooled heat dissipation mechanisms 3 are symmetrically arranged outside the water delivery module 11. The water-cooled heat dissipation mechanisms 3 are used to circulate the water flow in the water delivery module 11 to guide heat dissipation for the side walls of the ice-making refrigerator body 1. The water-cooled heat dissipation mechanisms 3 include connecting pipes 31 symmetrically connected to the outside of the water delivery module 11. Branch pipes 32 are connected to the outside of the connecting pipes 31, and fin groups 33 are installed on the outside of the branch pipes 32.

[0058] It should be noted that the outer wall of the fin group 33 is composed of no less than three arc fins, and the interiors of the arc fins are all designed to be hollow. The outside of the connecting pipe 31 is connected to no less than four branch pipes 32, and no less than three inclined columns are provided on the outsides of the branch pipes 32. A sliding connection is formed between the branch pipes 32 and the fin group 33 through the inclined columns and the arc fins.

[0059] Specifically, since the input end of the connecting pipe 31 is kept connected to the water delivery pipe in the water delivery module 11, and the output end of the connecting pipe 31 is kept connected to the recovery bin in the water delivery module 11, therefore, when the device needs to be filled with water for ice making, part of the water flow will flow through the connecting pipe 31 and fill the inside of the branch pipes 32. Since the inside of the fins is designed to be hollow and sleeved with the branch pipes 32, the water flow conveyed by the water delivery module 11 can flow inside the branch pipes 32 to form a heat conduction group inside the fins. Since water has a large latent heat of vaporization, in the formed heat pipe structure, when one end of the heat pipe contacts the high-temperature area inside the side wall of the device, the water absorbs heat and quickly evaporates into water vapor. Due to the flow characteristics of the water vapor, it will move towards the cooling end of the heat pipe. At the cooling end, the water vapor condenses into liquid water again when it meets the cold, releasing heat, and the heat is then dissipated to the external environment through the fin group 33. This heat pipe heat dissipation mechanism based on water effectively conducts the heat inside the side wall of the device and dissipates it to the outside.

[0060] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
