Description

Technical Field

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

[0002] In the commercial ice-making field (such as catering chains, medical cold chain, etc.), continuous ice makers have become the mainstream equipment due to their continuous ice production capacity. Traditional ice makers mostly use a single-sided refrigeration mode for their evaporators, with the ice grid only contacting the cold source on one side. The typical structure includes an evaporator plate set on one side connected to the corresponding refrigeration system, and single-sided refrigeration is achieved by setting ice grids on the surface of the evaporator plate. In practical applications, such equipment has the following significant defects: (1) Single-sided refrigeration causes ice to form only on one side of the evaporator plate, limiting the accumulation speed of the ice layer thickness and resulting in a low ice production volume per unit time; (2) The spray system is difficult to achieve uniform water film coverage in the ice grid, which easily causes problems such as uneven water flow distribution and low refrigeration efficiency. Utility Model Content

The outer side is away from the heat exchange plate and is an arc surface or an inclined surface. The connecting surfaces are connected between the outer side and the surface of the heat exchange plate, and an inclined angle is formed between the connecting surfaces and the surface of the heat exchange plate.

[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.

[0023] This utility model also provides an ice-making device, including the double-sided evaporator of the ice maker as described above.

[0024] The present invention has the following beneficial effects:

[0025] This invention relates to an ice maker with a double-sided evaporator 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 water flow through the ice grids, causing the water to freeze into ice blocks within the grids. At least two forming elements are present, located on opposite sides of the heat exchanger. This allows ice to form on both sides during heat exchange, significantly increasing the ice production rate and thus the ice production per unit time. Simultaneously, because the water flowing from the spraying element sequentially flows into the inner surfaces of the multiple ice grids within the same ice-making channel, the ice layer can grow directly from the inner surfaces of the ice grids, bringing the ice closer to the heat exchanger and resulting in higher heat exchange efficiency. Furthermore, since the multiple ice grids are interconnected within the ice-making channel, compared to the traditional method where water flows outside the ice grids, the water flow within the same ice-making channel is more stable, resulting in a more uniform water film coverage and improved refrigeration efficiency. This enables rapid and efficient ice making. Attached Figure Description

[0035] 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.

[0036] See Figure 1 and Figure 2 This utility model discloses a double-sided evaporator for an ice maker, including a heat exchanger 1, a forming component 2, and a spraying component 3. The heat exchanger 1 is used for evaporative heat exchange to make ice and condensative heat exchange to remove ice. The forming component 2 is used to manufacture 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 to make ice through evaporation. In the heating cycle, the heat exchanger 1 acts as a condenser to remove ice through heat release. Multiple ice trays 4 are formed between the forming component 2 and the heat exchanger 1. Water flows into the ice trays and freezes. The formed ice blocks are located in the ice trays 4. The spraying component 3 is located above the forming component 2 and is connected to an external water source. It can release 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 trays 4 of the forming component 2, causing the water to freeze in the ice trays 4.

[0037] 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 separately within the two molding components 2, avoiding waste of cold energy and improving its utilization efficiency. An ice-making channel 21 is provided on each 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 flows and exchanges heat, gradually growing into an ice layer.

[0038] Multiple ice trays 4 are interconnected within the ice-making channel, allowing water flowing from the top of the ice-making channel to sequentially enter each ice tray 4 during spraying. In traditional ice-making equipment, water flows along the outer edge of the ice tray for heat exchange. Since the outer edge of the ice tray has a very small area, almost only the thickness of the sheet, uneven water distribution is likely to occur. However, this embodiment of the invention, by connecting multiple ice trays 4 within the ice-making channel, achieves a larger water flow area, resulting in more uniform water distribution. Furthermore, the increased flow area reduces the water velocity, allowing the water to remain within the ice trays 4 for a sufficient time, thus achieving a adequate cooling effect.

[0039] The positions of the spray nozzles 32 of the spray element 3 correspond to the positions of the two forming elements 2 respectively. In one embodiment, two rows of spray nozzles 32 can be provided, with each spray element 3 having a row of spray nozzles 32. Each row of spray nozzles 32 can provide water flow to each forming element 2 individually, and the water flowing out of the spray element 3 can flow sequentially into the inner surface of multiple ice grids 4 in the same ice-making channel 21.

[0040] 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.

[0041] The beneficial effects of this utility model embodiment are as follows:

[0042] The double-sided evaporator of the ice maker in this embodiment of the utility model is provided with a heat exchange component 1, a forming component 2 and a spraying component 3. Multiple ice grid slots 4 are formed between the forming component 2 and the heat exchange component 1. The heat exchange component 1 can exchange heat with the water flow through the ice grid slots 4, so that the water freezes into ice blocks in the ice grid slots 4. The number of the molding parts 2 is at least two, and the two molding parts 2 are located on both sides of the heat exchanger 1, instead of being connected by welding. In this way, ice can be made on both sides during heat exchange, greatly increasing the amount of ice produced, thereby increasing the amount of ice produced per unit time. At the same time, the water flowing out of the spray can flow sequentially into the inner surface of multiple ice grid slots 4 in the same ice-making channel 21. The ice layer can grow directly from the inner surface of the ice grid slots 4, and the ice layer is closer to the heat exchanger 1, resulting in higher heat exchange efficiency. Moreover, since multiple ice grid slots 4 are interconnected in the ice-making channel 21, compared with the traditional method of ice layer growth where water flows outside the ice grid, the water flow in the same ice-making channel 21 is more stable, and the water film is evenly covered, improving the refrigeration efficiency and thus enabling rapid and efficient ice making.

[0043] See Figure 3The heat exchange component 1 includes a heat exchange tube 11 and a heat exchange plate 12. The heat exchange tube 11 is connected to an external refrigeration system and can absorb heat to make ice during refrigeration and release heat to remove ice during heating. The heat exchange plate 12 is made of stainless steel with no metal coating on its surface, which avoids corrosion and damage after long-term use compared to traditional evaporator ice grid structures. There are two heat exchange plates 12, which are parallel to each other and abut against each other. The heat exchange tube 11 is connected to the inner side of the two heat exchange plates 12, so that the refrigerant in the heat exchange tube 11 enters the heat exchange plate 12 and then flows from the heat exchange plate 12 back into the heat exchange tube 11. The heat exchange plates 12 on both sides correspond to the positions of the two molded parts 2. The refrigerant entering the heat exchange plate 12 can exchange heat with the molded parts 2, and the heat exchange tube 11 can transfer heat through the heat exchange plate 12, thereby freezing the water in the ice grid 4. The ice-making channel 21 abuts against the surface of the heat exchange plate 12, thereby improving the heat exchange efficiency.

[0044] The heat exchange plate 12 is provided with heat exchange grooves 122, which are recessed within the heat exchange plate 12. Depending on the area of ​​the heat exchange plate 12, the surrounding unit of the heat exchange grooves 122 can be U-shaped or S-shaped. After the two heat exchange plates 12 are parallel and abut against each other, the heat exchange grooves 122 on the two heat exchange plates 12 form a flow channel 14. The heat exchange tube 11 communicates with the flow channel 14, thereby enabling the refrigerant to be delivered into the heat exchange plate 12. In this embodiment of the invention, the two heat exchange plates 12 are welded together, and the heat exchange tube 11 is welded to the port of the flow channel 14.

[0045] See Figure 1 and Figure 4 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.

[0046] See Figure 4The heat exchange plate 12 is provided with multiple partitions 13. These partitions 13 are spaced apart within the same ice-making channel 21. Each partition 13 protrudes from the surface of the heat exchange plate 12, and its protrusion height is lower than that of the partition plate 22. A water flow gap 121 is provided between the two ends of each partition 13 and the partition plate 22. The partition plate 22 and the partitions 13 form the ice grid 4. In this embodiment, the length direction of the partitions 13 is perpendicular to the length direction of the partition plate 22. When water flows downwards in the water flow channel, it comes into contact with the partitions 13. The partitions 13 buffer the water flow, thereby extending the residence time of the water in the water flow channel, thus extending the heat exchange time and improving the heat exchange efficiency. The water flow gap 121 ensures the downward flow rate of the water. Furthermore, the partitions 13 horizontally separate the formed ice blocks, and together with the partition plate 22, they can form ice blocks with a rectangular bottom outline.

[0047] See Figure 3 and Figure 4 The heat pipe accommodating space 14 includes a transverse partition 141, which is the transverse portion of the heat pipe accommodating space 14. The transverse partition 141 is horizontally arranged on the heat exchange plate 12 and between two adjacent partitions 13. Thus, the partitions 13 and the transverse partition 141 are arranged in a "partition 13-transverse partition 141-partition 13" layout from top to bottom. The transverse partition 141, the partition plate 22, and the partitions 13 form the ice tray 4. Therefore, the transverse partition 141 also serves to buffer the water flow and prolong the residence time of the water in the water flow channel.

[0048] See Figure 7 The partition 13 includes an outer surface 131 and connecting surfaces 132 on the upper and lower sides of the outer surface 131. The outer surface 131 is the side of the partition 13 away from the heat exchange plate 12, and is an arc surface or inclined surface. The connecting surfaces 132 connect the outer surface 131 and the surface of the heat exchange plate 12, forming an inclined angle between the connecting surfaces 132 and the surface of the heat exchange plate 12, so that water flows over the partition 13 from top to bottom. The outer surface 131 being an arc surface or inclined surface away from the heat exchange plate 12 can reduce the impact of water flow on the outer surface 131 and avoid generating resistance to ice removal during subsequent ice removal.

[0049] See Figure 5The upper part of the molded part 2 is provided with a spray seat 24. The spray seat 24 has outer side plates 241 and guide plates 247 on both sides. Preferably, the position and number of 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 plates 241 and the guide plates 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] See Figure 7 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.

[0055] 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.

[0056] The bottom of the guide plate 247 is provided with a flow-guiding slope 2471. The flow-guiding slope 2471 is inclined from top to bottom from the side away from the molded part 2 to the side close to the molded part 2, so as to facilitate the water flow from the guide plate 247 directly to the surface of the heat exchange plate 12.

[0057] See Figure 8A 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.

[0058] 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.

[0059] This utility model embodiment also discloses an ice-making device (not shown in the accompanying drawings), including the double-sided evaporator of the ice maker as described above. The double-sided evaporator includes a heat exchange component 1, a forming component 2, and a spraying component 3. Multiple ice grids 4 are formed between the forming component 2 and the heat exchange component 1. The heat exchange component 1 can exchange heat with water flow through the ice grids 4, causing the water to freeze into ice blocks within the ice grids 4. The number of forming components 2 is at least two, with the two forming components 2 located on opposite sides of the heat exchange component 1, rather than being connected by welding. This allows ice to be made on both sides during heat exchange, significantly increasing the ice production rate and thus the ice production per unit time. Simultaneously, since heat exchange is available on both sides of the heat exchange component 1, the consumption of cooling capacity is reduced, improving refrigeration efficiency and enabling rapid and efficient ice making. The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
