Description

Technical Field

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

[0002] In the industrial and residential refrigeration sectors, water-cooled ice-making equipment is a rigid requirement in scenarios such as aquatic cold chain, chemical process cooling, and food processing. Its energy efficiency and ice-making efficiency directly affect the stability of quality and the user experience. Current mainstream ice-making equipment typically uses a single-sided ice-making plate as the heat transfer unit. This means the evaporator transfers cold energy only through a single metal plate (usually aluminum or copper), with the convex ice grid grooves forming a unidirectional water flow channel. This design has two technical drawbacks: firstly, over 50% of the evaporator's theoretical heat exchange area on the back side lacks an effective heat exchange interface, causing cold energy to dissipate into the environment through natural convection, resulting in low overall refrigeration efficiency; secondly, because the non-working surface of the evaporator lacks contact with ice-making components, the ice-making equipment can only produce ice on one side, resulting in a smaller quantity of ice and lower ice-making efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a double-sided ice-making evaporator that can perform double-sided refrigeration, thereby improving refrigeration efficiency and ice-making efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides a double-sided ice-making evaporator, including a heat exchange component, a spray component, and a receiving component. The heat exchange component is connected to the receiving component. The receiving component has multiple ice grid slots inside, which are used to hold shaped ice blocks. The spray component is located above the receiving component.

[0005] The containing assembly includes at least two containing covers, with the ice trays disposed within the containing covers. The two containing covers are respectively disposed on both sides of the heat exchange assembly and abut against the heat exchange assembly. Water flowing out of the spray assembly can flow into the ice trays of the two containing covers respectively.

[0006] As an improvement to the above solution, the heat exchange assembly includes a heat exchange tube and heat exchange plates disposed on both sides of the heat exchange tube. The heat exchange plates on both sides abut against the two sides of the heat exchange tube, and the positions of the two heat exchange plates correspond to the positions of the two receiving covers.

[0007] As an improvement to the above solution, the heat exchange tube is arranged around the two heat exchange plates, and the heat exchange tube has a contact surface on both sides, and the heat exchange plate abuts against the contact surface.

[0008] As an improvement to the above solution, the containment cover abuts against the side of the heat exchange plate away from the heat exchange tube.

[0009] As an improvement to the above solution, the containment hood includes multiple partitions, which are evenly distributed in the containment hood and extend toward the side away from the heat exchange assembly. The partitions are vertically arranged, and two adjacent partitions and the heat exchange plate form an ice-making channel, through which water flowing out of the spray assembly can flow into the ice-making channel.

[0010] As an improvement to the above solution, the receiving cover is also provided with multiple partitions, which are evenly distributed in the receiving cover. The partitions are horizontally arranged and divide the ice-making channel into multiple areas. In each area, the partitions, the partitions and the heat exchange plate form an ice grid.

[0011] As an improvement to the above solution, the partition bar includes an outer side and connecting surfaces on the upper and lower sides of the outer side. The outer side is located on the side away from the heat exchange plate and is an arc surface or an inclined surface. The connecting surfaces connect 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.

[0012] As an improvement to the above solution, the upper part of the receiving cover is provided with a spray fixing part, the end of the spray fixing part is provided with a fixing slot, and the spray assembly includes a spray component that can be snapped into the fixing slot.

[0013] As an improvement to the above solution, the number of spray elements is at least two, and each of the two spray elements is provided with a water spray nozzle at its lower part, with the water spray nozzle tilted towards the heat exchange plate.

[0014] As an improvement to the above solution, the upper part of the containment shroud is also provided with a flow guiding slope. The flow guiding slope is inclined from top to bottom from the side away from the heat exchange plate to the side closer to the heat exchange plate, and the water spray nozzle is inclined towards the flow guiding slope.

[0025] Figure 6 yes Figure 5 A magnified view of part A in the image. Detailed Implementation

[0026] 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.

[0027] See Figure 1 and Figure 2 This utility model discloses a double-sided ice-making evaporator, including a heat exchange component 1, a spray component 2, and a receiving component 3. The heat exchange component 1 is connected to the receiving component 3. The receiving component 3 is provided with a plurality of ice grids 311 for holding shaped ice blocks. The heat exchange component 1 can exchange heat with the liquid in the ice grids 311 of the receiving component 3 to freeze the liquid and make ice. The spray component 2 is located above the receiving component 3 and can provide water flow for ice making.

[0028] See Figure 2 To improve ice-making and heat exchange efficiency, the containing component 3 includes at least two containing covers 31. Ice trays 311 are disposed within the containing covers 31, with the openings of the ice trays 311 in opposite directions. The two containing covers 31 are respectively located on both sides of the heat exchange component 1 and abut against it, allowing for heat exchange with each of the two containing covers 31. The cold energy on both sides of the heat exchange component can be released within the two containing covers 31, avoiding waste of cold energy and improving its utilization efficiency. Water flowing from the spray component 2 can flow into the ice trays 311 of the two containing covers 31, where it undergoes heat exchange and gradually grows into an ice layer.

[0029] 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 21 directly enters the inner surface of the ice tray trough 311, rather than from its outer edge. Therefore, during heat exchange, on the one hand, the water is closer to the heat exchange element, reducing heat transfer stages. 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 trough 311 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 trough 311 for a sufficient time, resulting in more thorough heat exchange and improved heat exchange efficiency.

[0030] The beneficial effects of this utility model embodiment are as follows:

[0031] This utility model's double-sided ice-making evaporator includes a heat exchange component 1, a spray component 2, and a receiving component 3. The receiving component 3 includes at least two receiving covers 31, each containing multiple ice trays 311 for holding formed ice blocks. The two receiving covers 31 are respectively located on both sides of the heat exchange component 1 and abut against it. During ice making, the cooling energy from both sides of the heat exchange component 1 can be utilized. This reduces cooling energy consumption on the other side of the heat exchange component 1, improving heat exchange efficiency. Furthermore, it allows for concentrated use of both sides of the heat exchange component 1, enabling simultaneous ice making from both sides, thus improving ice-making efficiency. Therefore, this utility model enables double-sided refrigeration, improving both refrigeration and ice-making efficiency.

[0032] See Figure 3The heat exchange assembly 1 includes a heat exchange tube 11 and heat exchange plates 12 disposed on both sides of the heat exchange tube 11. 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 plates 12 are made of stainless steel with no metal coating on the surface, which avoids corrosion and damage after long-term use compared to traditional evaporator ice grid structures. The heat exchange plates 12 on both sides abut against the two sides of the heat exchange tube 11, and the two sides of the heat exchange tube 11 can transfer heat to the heat exchange plates 12 respectively. The positions of the two heat exchange plates 12 correspond to the positions of the two receiving shrouds 31, so that they can exchange heat with the liquid in the two receiving shrouds 31 respectively. This structure allows the cooling capacity to be transferred bidirectionally along the thickness direction of the heat exchange plates 12 when the refrigerant flows through the heat exchange tube 11, effectively utilizing the heat transfer area on both sides of the heat exchange tube 11.

[0033] The heat exchange tube 11 is arranged around the two heat exchange plates 12. Each heat exchange tube 11 has a contact surface 111 on both sides, and the heat exchange plates 12 abut against the contact surfaces 111. Depending on the area of ​​the heat exchange plates 1212, the surrounding unit of the heat exchange tube 1111 can be U-shaped or S-shaped. The U-shaped or S-shaped structure can enhance the refrigerant turbulence effect and simultaneously form a uniformly distributed cold output plane on both sides of the contact surfaces 111, ensuring a uniform distribution of cold energy across all parts of the heat exchange plates 12.

[0034] The containment cover 31 abuts against the side of the heat exchange plate 12 away from the heat exchange tube 11, and can be tightly attached to the surface of the heat exchange plate 12 away from the heat exchange tube 11 by means of bolts, forming a heat transfer path of "heat exchange tube 11-heat exchange plate 12-containment cover 31".

[0035] See Figure 4 The receiving cover 31 includes multiple partitions 312, which are evenly distributed within the receiving cover 31 and extend away from the heat exchange assembly 1. The partitions 312 are integrally formed with the base of the receiving cover 31 and are vertically arranged to form channels through which water flows. Two adjacent partitions 312 and the heat exchange plate 12 form an ice-making channel 32. Water flowing from the spray assembly 2 can flow into the ice-making channel 32, where it can directly exchange heat with the heat exchange plate 12. That is, the bottom side of the ice-making channel 32 is the heat exchange plate 12, allowing the water entering the ice-making channel 32 to directly exchange heat, resulting in high heat exchange efficiency. Furthermore, the partitions 312 create a laminar flow effect as the spray water flows through the ice-making channel 32, slowing the water flow and extending the heat exchange time, thereby improving heat exchange efficiency.

[0036] Furthermore, the receiving cover 31 is also provided with a plurality of partitions 33, which are evenly distributed in the receiving cover 31. The partitions 33 are horizontally arranged and are perpendicular to the partition plate 312 to form a rectangle. The plurality of partitions 33 divide the ice-making channel 32 into a plurality of regions. In each region, the partitions 33, the partition plate 312 and the heat exchange plate 12 form an ice grid 311. Therefore, the ice-making channel 32 is provided with a plurality of ice grids 311, and the plurality of ice grids 311 can be interconnected so that water can flow from top to bottom through each ice grid 311.

[0037] In each ice grid trough 311 region formed by the partition bar 33, the partition plate 312 and the heat exchange plate 12, the water flow forms a stable wall-attached flow under the action of gravity, wherein the partition bar 33 can further slow down the flow rate of the water and prolong the heat exchange time of the water flow in the ice-making channel 32.

[0038] Further, see Figure 4 The spacer 33 includes an outer surface 331 and connecting surfaces 332 on the upper and lower sides of the outer surface 331. The outer surface 331 is the side of the spacer 33 away from the heat exchange plate 12. The outer surface 331 away from the heat exchange plate 12 is an arc surface or an inclined surface. The connecting surfaces 332 connect the outer surface 331 and the surface of the heat exchange plate 12, forming an inclined angle between the connecting surfaces 332 and the surface of the heat exchange plate 12, so that the water flow can sweep across the spacer 33 from top to bottom. The outer surface 331 away from the heat exchange plate 12 and being an arc surface or an inclined surface can reduce the impact of the water flow on the outer surface 331 and avoid generating resistance to the ice during subsequent ice removal.

[0039] See Figure 2 The upper part of the receiving cover 31 is provided with a spray fixing part 34 for fixing the spray assembly 2. The end of the spray fixing part 34 is provided with a fixing slot 341. The spray assembly 2 includes a spray component 21. The fixing slot 341 is arc-shaped and can accommodate the spray component 21 to be snapped in. During installation, the spray component 21 can be snapped into the fixing slot 341, thereby fixing both ends of the spray component 21.

[0040] The number of spray elements 21 is at least two, and each of the two spray elements 21 is provided with a water spray nozzle 211 at its lower part. The water spray nozzle 211 is inclined toward the heat exchange plate 12, which can directly spray water onto the heat exchange plate 12 and shorten the path of water flow through the heat exchange plate 12.

[0041] See Figure 5The upper part of the receiving cover 31 is also provided with a guide slope 313. The guide slope 313 is inclined from top to bottom from the side away from the heat exchange plate 12 to the side closer to the heat exchange plate 12. The water nozzle 211 is inclined towards the guide slope 313. After the water flows towards the guide slope 313, it flows down from the guide slope 313. The guide slope can ensure that the water can flow directly to the surface of the heat exchange plate 12.

[0042] See Figure 4 To secure the receiving cover 31, a fixing ring 35 is provided on the side of the receiving cover 31. The fixing ring 35 has a fixing hole 351. During installation, screws or other fasteners are used, and the two receiving covers 31 can be connected to each other through the fixing hole 351. After the two receiving covers 31 are connected, they can press the heat exchange plate 12 in the middle, forming a tight heat transfer connection.

[0043] In this embodiment of the utility model, the heat exchange plate 12 is a flat plate and the heat exchange plate 12 is a stainless steel plate. The flat plate has better heat transfer uniformity, which is conducive to linear heat transfer. The stainless steel material has no metal coating on its surface, which can avoid corrosion and damage after long-term use compared with the traditional evaporator ice grid structure.

[0044] This utility model also discloses an ice-making device (not shown in the accompanying drawings), including a double-sided ice-making evaporator as described above. The double-sided ice-making evaporator is provided with a heat exchange component 1, a spray component 2, and a receiving component 3. The receiving component 3 includes at least two receiving covers 31, and each receiving cover 31 has multiple ice grid slots 311 for accommodating shaped ice blocks. The two receiving covers 31 are respectively located on both sides of the heat exchange component 1 and abut against the heat exchange component 1. During ice making, the cooling energy on both sides of the heat exchange component 1 can be utilized. On the one hand, this reduces the cooling energy consumption on the other side of the heat exchange component 1, improving heat exchange efficiency. On the other hand, it concentrates the use of both sides of the heat exchange component 1 for simultaneous ice making on both sides, improving ice making efficiency. Therefore, this utility model can perform double-sided refrigeration, improving both refrigeration and ice-making efficiency.

[0045] 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.
