Description

Technical Field

[0001] This utility model relates to the field of ice-making equipment technology, and in particular to an evaporator and ice-making equipment for a continuous ice-making system. Background Technology

[0002] Flow-type ice-making equipment is widely used in the ice-making industry, but its core ice-making efficiency is limited by the heat transfer path design of the evaporator and ice grid structure. Flow-type ice-making equipment typically has an evaporator with multiple ice grid slots. These slots are convex and used to store formed ice blocks. In existing flow-type ice-making equipment, the water sprayed by the spray mechanism must flow from the outer edge of the ice grid slots and undergo heat conduction through the thickness of the sidewall of the slot. After the water flows into contact with the outer surface of the ice grid slot, the cold energy must penetrate the thickness of the ice grid profile (usually 20-30mm) to be transferred to the water interface inside the slot, forming a long heat transfer path of "cold source-heat exchange plate-slot wall-water flow". This structure leads to an extended effective heat transfer path for the cold energy, and the cold energy is prone to gradient loss due to the thermal resistance of the material when penetrating the ice grid profile, thus greatly limiting the heat transfer efficiency and ice-making efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an evaporator for a flowing ice-making device, which can directly exchange heat with the liquid on the inner side of the ice grid, thereby improving heat exchange efficiency and ice-making efficiency.

The heat exchange component is connected to an external refrigeration system. Multiple ice grid slots are formed between the forming component and the heat exchange component.

The ice-making channel abuts against the surface of the heat exchange plate through the hollow hole, and the water flowing out of the spray component can flow to the surface of the heat exchange plate.

[0012] As an improvement to the above solution, the side of the heat exchange section away from the first heat exchange groove protrudes from the surface of the heat exchange plate, and the outer wall of the heat exchange section and the outer wall of the heat exchange plate respectively form a transverse partition on both sides of the heat exchange plate, the transverse partition dividing the heat dissipation channel into at least two parts.

[0013] As an improvement to the above solution, the molding surface is provided with multiple partitions. In the same ice-making channel, the multiple partitions are spaced apart. The partitions abut against the surface of the heat exchange plate and protrude from the surface of the heat exchange plate. The transverse partition is horizontally arranged on the heat exchange plate and between two adjacent partitions. The transverse partition, the partition, and the partitions form the ice grid groove.

[0014] As an improvement to the above solution, the upper part of the molded part is provided with a spray seat, and the two sides of the spray seat are respectively provided with an outer side plate and a guide plate. The outer side plate and the guide plate form a fixing groove. The position of the fixing groove corresponds to the position of the spray component. The spray component can be fixed in the fixing groove. The end of the fixing groove is provided with a fixing slot. The spray component can be snapped into the fixing slot.

[0015] As an improvement to the above solution, a positioning post is provided on the outside of the fixing groove, and a positioning through hole is provided at the bottom of the spray component, so that the positioning post can be inserted into the positioning through hole.

The water outlet is located on the bottom side of the spray seat and is connected to the heat exchange plate. The water outlet can be connected to the ice-making channel.

[0018] As an improvement to the above solution, the spray seat further includes a water guiding slope, which is located above the molded part. The upper part of the water guiding slope is connected to the bottom of the outer side plate, and the water outlet is located at the bottom of the water guiding slope.

[0022] The present invention has the following beneficial effects:

[0023] This utility model relates to an evaporator for a water-based ice-making device, comprising a heat exchanger, a forming element, and a spraying element. Multiple ice grids are formed between the forming element and the heat exchanger. The heat exchanger exchanges heat with the water flow through these ice grids, causing the water to freeze into ice blocks within the grids. The heat exchanger is located on the water inlet side of the ice grids. During use, water flows directly into the inner wall of the ice grids through the ice-making channel. Because the heat exchanger is located on the water inlet side, the water flows directly through it, directly transferring heat. The heat transfer path is "cold source - heat exchanger wall - water flow," significantly reducing the heat transfer distance, thereby minimizing heat loss and improving heat exchange efficiency. Furthermore, at least two forming elements are used, each located on one side of the heat exchanger, allowing heat exchange and ice making to occur on both sides of the evaporator, further improving both heat exchange and ice-making efficiency.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0034] See Figure 1 and Figure 2 This utility model discloses an evaporator for a water-cooled ice-making device, comprising a heat exchanger 1, a forming component 2, and a spraying component 3. The heat exchanger 1 is used for evaporative heat exchange for ice making and condensative heat exchange for ice removal. The forming component 2 is used for manufacturing ice blocks, and the spraying component 3 is used to provide water flow. The heat exchanger 1 is connected to an external refrigeration system. In the refrigeration cycle, the heat exchanger 1 acts as an evaporator, capable of evaporative ice making; in the heating cycle, the heat exchanger 1 acts as a condenser, capable of exothermic ice removal. Multiple ice grids 4 are formed between the forming component 2 and the heat exchanger 1. Water flows into the ice grids and freezes. The formed ice blocks are located in the ice grids 4. The spraying component 3 is located above the forming component 2 and is connected to an external water source, capable of releasing water flow towards the forming component 2. The water flow flows into the forming component 2, and the heat exchanger 1 can exchange heat with the water flow in the ice grids 4 of the forming component 2, causing the water to freeze in the ice grids 4.

[0035] See Figure 2 To improve ice-making and heat exchange efficiency, at least two molding components 2 are used. The ice grid slots 4 within the two molding components 2 have opposite opening directions. The heat exchanger 1 is positioned between the two molding components 2, allowing ice to be made within both molding components 2. Furthermore, the cold energy on both sides of the heat exchanger 1 can be released within the two molding components 2, avoiding waste of cold energy and improving its utilization efficiency. An ice-making channel 21 is provided on the molding component, and water from the sprayer 3 can be sprayed towards the ice-making channel 21. The ice-making channel 21 and the heat exchanger 1 form the ice grid slot 4, where water exchanges heat and gradually grows into an ice layer. The heat exchanger 1 is located on the water inlet side of the ice grid 4. When water is introduced, the water flow can directly flow into the side wall of the heat exchanger 1, forming a heat exchange path of "cold source-heat exchanger-water flow". Compared with the heat exchange path of "cold source-heat exchange plate-tank wall-water flow" in traditional water-flow ice making equipment, the heat exchange path is greatly shortened, reducing heat transfer loss and thus improving heat exchange efficiency.

[0036] In traditional ice-making equipment, water flows from the outer edge of the ice tray, with some water entering the inner side of the tray and gradually forming ice. However, in this embodiment, the water from the spray element 3 directly enters the inner surface of the ice tray 4, rather than from its outer edge. Therefore, during heat exchange, on the one hand, the water is closer to the heat exchange element 1, reducing heat transfer steps. A shorter heat transfer path results in lower thermal resistance and higher heat transfer efficiency. On the other hand, the water flow area entering the inner side of the ice tray 4 is larger than that of the water flow area along the outer edge of a traditional ice tray. This not only increases the heat exchange area but also reduces the water flow velocity, allowing the water to remain in the ice tray 4 for a sufficient time, resulting in more thorough heat exchange and improved heat exchange efficiency.

[0037] See Figure 6 The bottom of the spray component 3 is provided with a water spray nozzle 32. The distribution position of the water spray nozzle 32 corresponds to the two molded components 2 respectively. In one embodiment, two rows of water spray nozzles 32 can be provided. Each row of water spray nozzles 32 can provide water flow to each molded component 2 individually. The water spray nozzles 32 can be connected to the ice making channel 21, so that the water flowing out of the spray component 3 can flow into the inner surface of the ice grid 4.

[0038] The beneficial effects of this utility model embodiment are as follows:

[0039] This embodiment of the utility model provides an evaporator for a water-flow ice-making device, comprising a heat exchanger 1, a forming element 2, and a spraying element 3. Multiple ice grids 4 are formed between the forming element 2 and the heat exchanger 1. The heat exchanger 1 can exchange heat with the water flow through the ice grids 4, causing the water to freeze into ice blocks within the ice grids 4. The heat exchanger 1 is located on the water inlet side of the ice grids 4. During use, the water flows directly into the inner wall surface of the ice grids 4 through the ice-making channel 21. Because the heat exchanger 1 is located on the water inlet side of the ice grids 4, the water flows directly through the heat exchanger 1, directly transferring heat to it. The heat transfer path is "cold source - heat exchanger 1 - water flow," significantly reducing the heat transfer distance, thereby reducing heat loss and improving heat exchange efficiency. Furthermore, the number of forming elements 2 is at least two, with two forming elements 2 located on opposite sides of the heat exchanger 1, enabling heat exchange and ice making on both sides of the evaporator, further improving both heat exchange and ice-making efficiency.

[0040] Specifically, see Figure 3 and Figure 4The heat exchanger 1 includes a heat exchange plate 11 and a heat exchange plate 12. The area of ​​the heat exchange plate 11 is not greater than the area of ​​the heat exchange plate 12. The heat exchange plate 12 is provided with a heat exchange part 121. A first heat exchange groove 1211 is provided on one side of the heat exchange part 121. The first heat exchange groove 1211 is recessed into one side surface of the heat exchange plate 12 and can form an internal space. The heat exchange plate 11 is provided with a second heat exchange groove 111. The second heat exchange groove 111 is recessed into the surface of the heat exchange plate 11 and can also form an internal space. The first heat exchange groove 1211 and the second heat exchange groove 111 can form a heat exchange channel 14. The heat exchange channel 14 is tubular. An external refrigeration system can be connected to the heat exchange channel 14, allowing refrigerant to flow and exchange heat between the heat exchange fins 11 and the heat exchange plate 12. The ice-making channel 21 on the molded part 2, by tightly fitting against both sides of the heat exchange plate 12, allows the cold energy absorbed by the heat exchange plate 12 to be directly transferred to the inner wall of the ice tray 4. The two ice-making channels 21 on the molded parts 2 can respectively abut against the surfaces on both sides of the heat exchange plate 12, thus allowing the refrigerant to directly exchange heat with the liquid within the ice-making channel 21.

[0041] Specifically, see Figure 7 The maximum depth of the first heat exchange groove 1211 on the heat exchange plate 12 is less than the maximum width of the first heat exchange groove 1211 on the heat exchange plate 12, and the maximum depth of the second heat exchange groove 111 on the heat exchange plate 11 is less than the maximum width of the second heat exchange groove 111 on the heat exchange plate 11. The first heat exchange groove 1211 on the heat exchange plate 12 is distributed on the surface in a shallow, wide recessed shape, and the second heat exchange groove 111 on the heat exchange plate 11 adopts a matching shallow groove structure. When the two are combined, they form a heat exchange channel 14 with a flat cross-section. The flattened design of the heat exchange channel 14 allows the refrigerant to form a thin, uniformly distributed flow pattern when flowing through it. The structural feature that the depth of the heat exchange channel 14 is less than its width allows the refrigerant to quickly cover the heat transfer area on the surface of the heat exchange plate 12 when flowing through the heat exchange channel 14. The heat exchange channel 14 has a larger heat exchange area in the ice-making channel 21 and higher heat exchange efficiency.

[0042] The heat exchanger 1 further includes an external connecting pipe 16. The first heat exchange groove 1211 has a first end 1212 at its end, and the second heat exchange groove 111 has a second end 112 at its end. The second end 112 has a connecting hole 1121. One end of the external connecting pipe 16 can pass through the connecting hole 1121 and be sealed and connected to the heat exchange channel 14. After the heat exchange plates 11 and 12 of the heat exchanger 1 are welded to form the internal heat exchange channel 14, the external connecting pipe 16 is inserted into the end of the heat exchange channel 14 through the connecting hole 1121 of the second end 112. The outer wall of the external connecting pipe 16 and the inner wall of the connecting hole 1121 are sealed together by an circumferential weld.

[0043] The heat exchange fins 11, heat exchange plates 12, and external connecting pipes 16 are made of stainless steel. The heat exchange fins 11 and heat exchange plates 12 are connected by welding, and the external connecting pipes 16 are connected to the connecting holes 1121 by welding. A dense chromium oxide passivation layer is directly formed at the welding interface between the heat exchange fins 11 and the heat exchange plates 12, achieving food-grade surface corrosion resistance without additional electroplating, fundamentally avoiding the risk of metal ion contamination caused by the peeling off of the copper electroplating layer.

[0044] The ice-making channels 21 extend vertically downwards, and there are multiple ice-making channels 21 evenly distributed on the molding part 2. Water sprayed from the spray element 3 can enter the ice-making channels 21 to make ice. The ice-making channels 21 have partitions 22 on both sides, which can separate the water flow and vertically separate the formed ice blocks. A perforated hole 23 is provided between the two partitions 22, and the ice-making channels 21 abut against the surface of the heat exchange plate 12 through the perforated hole 23, allowing water from the spray element 3 to flow onto the surface of the heat exchange plate 12. Therefore, compared to the traditional structure and method of freezing ice by flowing water from the outside of the ice tray, this embodiment of the invention allows water to flow directly over the surface of the heat exchange plate 12. The water flow is closer to the heat exchange plate 12, reducing heat transfer links. The shorter the heat transfer path, the lower the thermal resistance, and the higher the heat transfer efficiency.

[0045] The side of the heat exchange section 121 furthest from the first heat exchange groove 1211 protrudes from the surface of the heat exchange plate 12. The outer wall of the heat exchange section 121 and the outer wall of the heat exchange plate 11 respectively form a transverse partition 141 on both sides of the heat exchange plate 11. The transverse partition 141 is horizontally arranged and perpendicular to the water flow direction, dividing the heat dissipation channel into at least two parts. The transverse partition 141 can form a barrier to the water flow, buffering the water flow and prolonging the residence time of the water flow in the water channel.

[0046] See Figure 5The forming process includes multiple partitions 13 spaced apart within the same ice-making channel 21. Each partition 13 abuts against and protrudes from the surface of the heat exchange plate 12. The protrusion height of the partition 13 is lower than that of the partition 22. The length direction of the partition 13 is perpendicular to the length direction of the partition 22. When water flows downwards in the water channel, it comes into contact with the partitions 13, which buffer the water flow, thus extending the residence time of the water in the water channel and improving heat exchange efficiency. Furthermore, the partitions 13 horizontally separate the formed ice blocks, allowing them to work in conjunction with the partition 22 to form ice blocks with a rectangular bottom profile. The horizontal partition 141 is horizontally arranged on the heat exchange plate 12 and between two adjacent partitions 13, so that the partitions 13 and the horizontal partition 141 are arranged in a "partition 13-horizontal partition 141-partition 13" layout from top to bottom, and the horizontal partition 141, the partition plate 22 and the partitions 13 form the ice grid 4.

[0047] See Figure 5 The upper part of the molded part 2 is provided with a spray seat 24. The spray seat 24 has an outer side plate 241 and a guide plate 247 on both sides. Preferably, the position and number of the spray seats 24 correspond to the position and number of the molded parts. The spray seat 24 can be integrally formed with the molded part 2 or fixed to the upper part of the molded part 2. The outer side plate 241 and the guide plate 247 are respectively located on both sides of the molded part 2, forming a fixing groove 242. The position of the fixing groove 242 corresponds to the position of the spraying part 3, and the fixing groove 242 can fix and accommodate the spraying part 3. Further, the end of the fixing groove 242 is provided with a fixing slot 243. The fixing slot 243 is arc-shaped and can accommodate the spraying part 3. During installation, the spraying part 3 can be fastened into the fixing slot 243, thereby fixing both ends of the spraying part 3.

[0048] See Figure 5 and Figure 6 To prevent the spray component 3 from rotating, a positioning post 244 is provided on the outer side of the fixing groove 242, and a positioning through hole 31 is provided at the bottom of the spray component 3. The positioning post 244 can be inserted into the positioning through hole 31. Under the limitation of the positioning post 244, the spray component 3 will not rotate, thereby ensuring the spray angle of the water flow.

[0049] To match the ice production volume and ensure the ice-making speed, the number of spray elements 3 is at least two. Each spray element 3 corresponds to one of the two forming elements 2. Each spray element 3 can provide water flow to each forming element 2 independently, and the water flowing from the spray element 3 can flow into the inner surface of the ice tray 4. The lower part of each spray element 3 is provided with a water nozzle 32, which is vertically or inclined towards the water flow channel to supply water to the forming elements 2.

[0050] See Figure 7 The spray base 24 has a water outlet 245 at its bottom, which is located above the two molded parts 2. Water sprayed from the spraying parts 3 can enter the water outlet 245 and flow out from the water outlet 245 onto the molded parts 2. Specifically, the water outlet 245 is located on the bottom side of the spray base 24. The water outlet 245 is connected to the heat exchange plate 12 and can communicate with the ice making channel 21.

[0051] Since both the partition plate 22 and the partition block 13 protrude outward from the surface of the heat exchange plate 12, forming the ice tray 4, the heat exchange plate 12 is the bottom of the ice tray 4 and the component closest to the heat exchange tube 11. Therefore, the temperature of the heat exchange plate 12 is the lowest during ice making. The water outlet 245 is connected to the heat exchange plate 12. Because the heat exchange plate 12 is the bottom of the ice tray 4 and its temperature is the lowest during ice making, the water flowing from the water outlet 245 into the heat exchange plate 12 flows directly into the inner surface of the ice tray 4. Compared to the traditional water-flow ice maker where the water flows from the outer edge of the ice tray (i.e., the outside of the ice tray), the heat exchange temperature is lower, the heat exchange area is larger, and therefore the heat exchange is more complete and efficient.

[0052] See Figure 8 To ensure water flow into the surface of the main body of the plate, the spray base 24 further includes a water guiding slope 246. The water guiding slope 246 is located above the molded part 2, and its upper part is connected to the bottom of the outer side plate 241. The water outlet 245 is located at the bottom of the water guiding slope 246. The water guiding slope 246 slopes from top to bottom from the outer side plate 241 towards the inner side of the spray base 24. Thus, the water sprayed from the nozzle 32 falls onto the water guiding slope 246. Because the water guiding slope 246 slopes from top to bottom from the outer side plate 241 towards the inner side of the spray base 24, the water flow is concentrated on the inner side of the spray base 24, i.e., at the location of the water outlet 245, and finally discharged from the water outlet 245 onto the main body of the plate.

[0053] The guide plate 247 is vertically disposed in the middle of the spray seat 24. The bottom of the water guiding slope 246 and the bottom of the guide plate 247 form the water outlet 245. Water flows through the water guiding slope 246 and the guide plate 247. The water outlet 245 is located on the side of the top of the water channel close to the heat exchange plate 12 to ensure that the water can flow directly to the surface of the heat exchange plate 12.

[0054] See Figure 8 A partition strip 25 is provided between adjacent ice-making channels 21. The partition strip 25 is surrounded by the partition plates 22 on both sides. The top of the partition strip 25 is connected to the outside of the water-guiding inclined surface 246. When water flows in the ice-making channel 21, the partition strip 25 can separate the water flow and prevent water from entering the partition strip 25. The partition strip 25 has a receiving groove 251 on the side near the heat exchanger 1. The evaporator of the water-flow ice maker also includes an abutment strip 5. One side of the abutment strip 5 is fixed in the receiving groove 251, and the other side of the abutment strip 5 can abut against the surface of the heat exchange plate 12. The abutment strip 5 is made of silicone material, which can improve the sealing between the partition plate 22 and the heat exchange plate 12. The receiving groove 251 can press the abutment strip 5 tightly against the surface of the heat exchange plate 12, thereby achieving a sealing and isolation effect. Water can only flow in the same ice-making channel 21 and will not seep into other ice-making channels 21.

[0055] In addition, see Figure 9 To secure the abutment strip 5, a mounting groove 252 is provided on the side of the spacer strip 25 away from the heat exchange plate 12. A fixing through hole 2521 is provided within the mounting groove 252. A fixing hole 51 is provided on the abutment strip 5, and a locking hole 15 is provided on the heat exchange component 1. The fixing through hole 2521, fixing hole 51, and locking hole 15 are positioned sequentially. Using screws or other fasteners, the abutment strip 5 can be fixed to the heat exchange plate 12 through the fixing through hole 2521, fixing hole 51, and locking hole 15. Furthermore, the spacer strip 25 can isolate water flow, preventing water from entering the spacer strip 25 and thus preventing the fasteners from rusting.

[0056] This utility model embodiment also discloses an ice-making device (not shown in the accompanying drawings), including an evaporator for a flowing water ice-making device as described above. The evaporator for the flowing water ice-making device is provided with a heat exchanger 1, a forming element 2, and a spraying element 3. Multiple ice grids 4 are formed between the forming element 2 and the heat exchanger 1. The heat exchanger 1 can exchange heat with the water flow through the ice grids 4, causing the water to freeze into ice blocks within the ice grids 4. The heat exchanger 1 is located on the water inlet side of the ice grids 4. In use, the water flow directly enters the inner wall surface of the ice grids 4 through the ice-making channel 21. Because the heat exchanger 1 is located on the water inlet side of the ice grids 4, the water flow directly passes through the heat exchanger 1 and directly transfers heat to it. The heat transfer path is "cold source - heat exchanger 1 - water flow," greatly reducing the heat transfer distance, thereby reducing heat loss and improving heat exchange efficiency.
