Description

Technical Field

[0001] The present invention relates to the technical field of ice-making equipment, and in particular to an evaporator for running water ice-making equipment and ice-making equipment. Background Art

[0002] As one of the common equipment in the ice-making industry, the running water ice-making equipment is applied in multiple fields such as fishery refrigeration, chemical reaction cooling, and food processing and preservation. The operating efficiency of the running water ice-making equipment is closely related to the structural design of the evaporator and the heat conduction efficiency of the ice-making components. Optimizing the synergistic effect between the two has become the main direction of technological upgrading in the industry. The evaporators of existing running water ice-making equipment usually use a single-sided ice-making plate for ice-making. Multiple outwardly convex ice grid grooves are provided on the ice-making plate, and water flows from the outside of the ice grid grooves, and ice blocks are finally formed inside the ice grid grooves. On the one hand, this structure restricts the evaporator to only conduct heat transfer through a single-sided ice-making plate, forming a linear heat transfer path of "single evaporation surface - single ice-making surface". Therefore, more than 50% of the theoretical heat exchange area of the evaporator is in an ineffective working state. Moreover, due to a certain distance between the outside and the inside of the ice grid grooves, when the water flows outside the ice grid grooves, the cold in the ice-making plate is transmitted through the profile thickness direction of the ice grid grooves. This transmission distance is relatively long, and the heat transfer efficiency is low. In addition, the cold on the other side of the evaporator is finally dissipated in the form of convective heat dissipation, resulting in a low ice-making efficiency of the equipment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an evaporator for running water ice-making equipment, which can perform double-sided ice-making, and the water flow can directly exchange heat on the inner wall of the ice grid grooves, with high heat exchange efficiency and ice-making efficiency.

[0004] To solve the above technical problem, the present invention provides an evaporator for running water ice-making equipment, including a heat exchange member, a forming member, and a spraying member.

The spraying part can be buckled into the fixing buckles.

[0016] As an improvement to the above solution, positioning columns are provided on the outer side of the fixing groove. Positioning through holes are provided at the bottom of the spraying part. The positioning columns can be inserted into the positioning through holes.

[0036] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0037] See Figure 1 and Figure 2 , an evaporator of a flowing water ice-making device according to an embodiment of the present invention includes a heat exchange part 1, a forming part 2 and a spraying part 3. The heat exchange part 1 is used for evaporative heat exchange for ice-making and condensing heat exchange for ice-removing. The forming part 2 is used for manufacturing ice blocks, and the spraying part 3 is used for providing water flow. The heat exchange part 1 is communicated with an external refrigeration system. In the refrigeration cycle, the heat exchange part 1 is an evaporator and can perform evaporative ice-making. In the heating cycle, the heat exchange part 1 is a condenser and can perform heat release for ice-removing. A plurality of ice cell grooves 4 are formed between the forming part 2 and the heat exchange part 1. Water flow freezes in the ice cells, and the formed ice blocks are located in the ice cell grooves 4. The spraying part 3 is arranged above the forming part 2. The spraying part 3 is communicated with an external water source and can release water flow towards the forming part 2. The water flow flows into the forming part 2, and the heat exchange part 1 can exchange heat with the water flow in the ice cell grooves 4 of the forming part 2, so that the water flow freezes in the ice cell grooves 4.

[0038] See Figure 2 , in order to improve the ice-making efficiency and heat exchange efficiency, the number of the forming parts 2 is at least two. The notch directions of the ice cell grooves 4 in the two forming parts 2 are opposite. The heat exchange part 1 is arranged between the two forming parts 2, so that ice-making is carried out in the two forming parts 2. Moreover, the cold quantity on both sides of the heat exchange part 1 can be released in the two forming parts 2 respectively, avoiding waste of cold quantity and improving the utilization efficiency of cold quantity. A ice-making channel 21 is arranged on the forming part. The water on the spraying part 3 can be sprayed towards the ice-making channel 21. The ice-making channel 21 and the heat exchange part 1 enclose the ice cell grooves 4, and the water flow exchanges heat in the ice cell grooves 4 and gradually grows into ice layers.

[0039] See Figure 7, a water spraying port 32 is provided at the bottom of the water spraying member 3, and the distribution positions of the water spraying ports 32 correspond to the two forming members 2 respectively. In one embodiment, two rows of water spraying ports 32 can be provided, and each row of water spraying ports 32 can independently provide water flow for each forming member 2, and the water flowing out of the water spraying member 3 can flow into the inner surface of the ice tray groove 4.

[0040] The water flow of traditional ice-making equipment flows along the outer edge of the ice tray. Part of the water flow can enter the inner side of the ice tray along the outer edge of the ice tray, and then ice blocks are gradually formed on the inner side of the ice tray. Different from the traditional ice-making equipment, in the embodiment of the present invention, the water flowing out of the water spraying member 3 can directly enter the inner surface of the ice tray groove 4 instead of entering from the outer edge of the ice tray groove 4. Therefore, during heat exchange, on the one hand, the water flow is closer to the heat exchange member 1, reducing the heat transfer link. The shorter the heat transfer path, the smaller the thermal resistance, and the higher the heat transfer efficiency; on the other hand, the water flow area entering the inner side of the ice tray groove 4 is larger than the water flow area of the outer edge of the traditional ice tray. Not only is the heat exchange area larger, but also due to the increase in the flow area, the water flow speed decreases, and the water can stay in the ice tray groove 4 for sufficient time, making the heat exchange more sufficient and also improving the heat exchange efficiency.

[0041] The beneficial effects of the embodiment of the present invention are as follows:

[0042] In the evaporator of the flowing water ice-making equipment according to the embodiment of the present invention, there are provided a heat exchange member 1, a forming member 2 and a water spraying member 3. A plurality of ice tray grooves 4 are formed between the forming member 2 and the heat exchange member 1. The heat exchange member 1 can exchange heat with the water flow through the ice tray grooves 4 to freeze the water in the ice tray grooves 4 into ice blocks. The number of the forming members 2 is at least two, and the two forming members 2 are respectively located on both sides of the heat exchange member 1, so that heat exchange can be carried out on both sides of the evaporator. The two forming members 2 can make ice simultaneously, and the cold quantity on both sides of the heat exchange member 1 can be utilized. Moreover, a water spraying port 32 is provided at the bottom of the water spraying member 3, and the distribution position of the water spraying port 32 corresponds to the positions of the two forming members 2. The water flow sprayed out of the water spraying port 32 can flow into the inner wall surface of the ice tray groove 4 through the ice-making channel 21. The distance between the water flow and the heat exchange member 1 is relatively close, and the heat exchange member 1 can directly cool the water flow. Compared with the traditional structural method of cooling the water flow outside the ice tray groove 4, it has higher heat transfer efficiency and ice-making efficiency.

[0043] Specifically, refer to Figure 3, the heat exchanger 1 includes heat exchange fins 11 and a heat exchange plate 12. The area of the heat exchange fins 11 is not greater than that of the heat exchange plate 12. Groove spaces are provided inside both the heat exchange fins 11 and the heat exchange plate 12. After the heat exchange fins 11 and the heat exchange plate 12 are abutted against each other, a heat exchange channel 14 can be formed. An external refrigeration system can be connected to the heat exchange channel 14, so that the refrigerant can enter and flow for heat exchange between the heat exchange fins 11 and the heat exchange plate 12. The ice-making channels 21 on the two forming members 2 can respectively abut against the surfaces on both sides of the heat exchange plate 12. Therefore, the refrigerant can directly exchange heat with the liquid in the ice-making channel 21.

[0044] See Figure 3 and Figure 4 , a heat exchange portion 121 is provided on the heat exchange plate 12. A first heat exchange groove 1211 is provided on one side of the heat exchange portion 121. The first heat exchange groove 1211 is recessed from one side surface of the heat exchange plate 12 to form an internal space. A second heat exchange groove 111 is provided on the heat exchange fins 11. The second heat exchange groove 111 is recessed from the surface of the heat exchange fins 11 to also form an internal space. The first heat exchange groove 1211 and the second heat exchange groove 111 can enclose the heat exchange channel 14. The heat exchange channel 14 is tubular. The ice-making channels 21 on the forming member 2 are in close contact with the surfaces on both sides of the heat exchange plate 12, so that the cold quantity absorbed by the heat exchange plate 12 can be directly transferred to the inner wall of the ice tray groove 4.

[0045] Specifically, see Figure 8 , 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. The maximum depth of the second heat exchange groove 111 on the heat exchange fins 11 is less than the maximum width of the second heat exchange groove 111 on the heat exchange fins 11. The first heat exchange grooves 1211 on the heat exchange plate 12 are distributed on the surface in a shallow and wide depression form. The second heat exchange grooves 111 on the heat exchange fins 11 adopt a matching shallow groove structure. After the two are aligned, a heat exchange channel 14 with a flat cross-section is formed. The flattened design of the heat exchange channel 14 enables the refrigerant to form a thin-layer and uniform distribution flow pattern when flowing through. The structural feature that the depth of the heat exchange channel 14 is less than the width enables 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 width surface of the heat exchange channel 14 in the ice-making channel 21 is larger and the heat exchange efficiency is higher.

[0046] The heat exchange member 1 further includes an external connection pipe 16. One end of the first heat exchange groove 1211 is provided with a first end 1212, and one end of the second heat exchange groove 111 is provided with a second end 112. A connection hole 1121 is provided on the second end 112. One end of the external connection pipe 16 can pass through the connection hole 1121 and be hermetically communicated with the heat exchange channel 14. After the heat exchange fins 11 of the heat exchange member 1 and the heat exchange plate 12 are welded to form the internal heat exchange channel 14, the external connection pipe 16 is inserted into the end of the heat exchange channel 14 through the connection hole 1121 of the second end 112, and the outer wall of the external connection pipe 16 and the inner wall of the connection hole 1121 are hermetically connected through a circumferential weld.

[0047] The heat exchange fins 11, the heat exchange plate 12 and the external connection pipe 16 are made of stainless steel. The heat exchange fins 11 and the heat exchange plate 12 are connected by a welding process, and the external connection pipe 16 and the connection hole 1121 are connected by a welding process. The welding interface between the heat exchange fins 11 and the heat exchange plate 12 directly forms a dense chromium oxide passivation layer, and the food contact-grade surface corrosion resistance requirement can be achieved without additional electroplating treatment, fundamentally avoiding the risk of metal ion pollution caused by the peeling of the copper electroplating layer.

[0048] The ice-making channel 21 extends vertically downward. The number of the ice-making channels 21 is multiple and they are evenly distributed on the forming member 2. The water flow sprayed from the spraying member 3 can enter the ice-making channel 21 for ice-making. The two sides of the ice-making channel 21 are partition plates 22, and the partition plates 22 can separate the water flow. At the same time, the formed ice cubes can be vertically separated by the partition plates 22. A hollow hole 23 is provided between the two partition plates 22. The ice-making channel 21 abuts against the surface of the heat exchange plate 12 through the hollow hole 23, and the water flowing out of the spraying member 3 can flow to the surface of the heat exchange plate 12. Therefore, compared with the traditional structure and method of freezing and ice-making by flowing water along the outer edge of the ice grid, in the embodiment of the present invention, the water flow can directly flow through the surface of the heat exchange plate 12, the water flow is closer to the heat exchange plate 12, reducing the heat transfer link. The shorter the heat transfer path, the smaller the thermal resistance, and the higher the heat transfer efficiency.

[0049] One side of the heat exchange part 121 away from the first heat exchange groove 1211 protrudes from the surface of the heat exchange plate 12. The outer wall of the heat exchange part 121 and the outer wall of the heat exchange fins 11 respectively form a horizontal partition part 141 on both sides of the heat exchange fins 11. The horizontal partition part is horizontally arranged and perpendicular to the water flow direction. The horizontal partition part 141 divides the heat dissipation channel into at least two parts. The horizontal partition part 141 can form a block for the water flow, playing a role in buffering the water flow and prolonging the residence time of the water flow in the flowing water channel.

[0050] See Figure 5, there are multiple partition blocks 13 provided on the forming part. In the same ice-making channel 21, the multiple partition blocks 13 are arranged at intervals. The partition blocks 13 are in contact with the surface of the heat exchange plate 12 and protrude from the surface of the heat exchange plate 12. The protruding height of the partition blocks 13 is lower than the protruding height of the partition plate 22. The length direction of the partition blocks 13 is perpendicular to the length direction of the partition plate 22. When water flows downward in the flowing water channel, it will contact the partition blocks 13. The partition blocks 13 can buffer the water flow, thereby prolonging the residence time of the water flow in the flowing water channel, and thus being able to prolong the heat exchange time and improve the heat exchange efficiency. In addition, the partition blocks 13 can horizontally partition the formed ice cubes, and cooperate with the partition plate 22 to form ice cubes with a rectangular bottom contour. The horizontal partition part 141 is horizontally arranged on the heat exchange plate 12 and is arranged between two adjacent partition blocks 13. In this way, the partition blocks 13 and the horizontal partition part 141 present an arrangement layout of "partition block 13 - horizontal partition part 141 - partition block 13" from top to bottom. The horizontal partition part 141, the partition plate 22 and the partition blocks 13 enclose the ice grid groove 4.

[0051] See Figure 6 , there is a spray seat 24 provided on the upper part of the forming part 2. Outer side plates 241 and guide plates 247 are respectively provided on both sides of the spray seat 24. Preferably, the position and quantity of the spray seat 24 correspond to the position and quantity of the forming part. The spray seat 24 can be integrally formed with the forming part 2 or fixed to the upper part of the forming part 2. The outer side plates 241 and the guide plates 247 are respectively arranged on both sides of the forming part 2. The outer side plates 241 and the guide plates 247 enclose a fixing groove 242. The position of the fixing groove 242 corresponds to the position of the spray part 3. The fixing groove 242 can fix and accommodate the spray part 3. Further, a fixing bayonet 243 is provided at the end of the fixing groove 242. The fixing bayonet 243 is arc-shaped and can accommodate the spray part 3 to be snapped in. During installation, the spray part 3 can be snapped into the fixing bayonet 243, thereby fixing both ends of the spray part 3.

[0052] See Figure 6 and Figure 7 , in order to prevent the spray part 3 from rotating, a positioning post 244 is provided on the outside of the fixing groove 242. A positioning through hole 31 is provided at the bottom of the spray part 3. The positioning post 244 can be inserted into the positioning through hole 31. Under the limitation of the positioning post 244, the spray part 3 will not rotate, thereby ensuring the spraying angle of the water flow.

[0053] To match the ice production capacity and ensure the ice-making speed, the number of the spraying members 3 is at least two. The two spraying members 3 respectively correspond to the two forming members 2. Each spraying member 3 can independently provide water flow for each forming member 2, and the water flowing out of the spraying member 3 can flow into the inner surface of the ice tray groove 4. A water spraying opening 32 is provided at the lower part of the spraying member 3, and the water spraying opening 32 faces the water flow channel vertically or obliquely, so as to supply water to the forming member 2.

[0054] See Figure 8 , a water outlet 245 is provided at the bottom of the spraying seat 24. The water outlet 245 is located above the two forming members 2. The water sprayed from the spraying member 3 can enter the water outlet 245 and flow out of the water outlet 245 onto the forming member 2. Specifically, the water outlet 245 is provided on the bottom side of the spraying seat 24, and the water outlet 245 is connected to the heat exchange plate 12. The water outlet 245 can be communicated with the ice-making channel 21.

[0055] Since both the partition plate 22 and the partition block 13 protrude from the surface of the heat exchange plate 12, the partition plate 22 and the partition block 13 enclose the ice tray groove 4. Therefore, the heat exchange plate 12 is the bottom of the ice tray groove 4, and the heat exchange plate 12 is the component closest to the heat exchange tube 11. Therefore, during ice-making, the temperature of the heat exchange plate 12 is the lowest. The water outlet 245 is connected to the heat exchange plate 12, and since the heat exchange plate 12 is the bottom of the ice tray groove 4 and the temperature of the heat exchange plate 12 is the lowest during ice-making, the water flow flowing from the water outlet 245 into the heat exchange plate 12 directly flows into the inner surface of the ice tray groove 4. Compared with the way that the water flow of the traditional flowing water ice-making machine flows from the outer edge (i.e., the outside) of the ice tray, the heat exchange temperature is lower, the heat exchange area is larger, so the heat exchange is more sufficient and the heat exchange efficiency is higher.

[0056] See Figure 9 , to ensure that the water flow can flow onto the surface of the plate body, the spraying seat 24 further includes a water guiding inclined surface 246. The water guiding inclined surface 246 is located above the forming member 2. The upper part of the water guiding inclined surface 246 is connected to the bottom of the outer side plate 241. The water outlet 245 is provided at the bottom of the water guiding inclined surface 246. The water guiding inclined surface 246 inclines from the outer side plate 241 towards the inside of the spraying seat 24 from top to bottom. In this way, the water flow sprayed from the water spraying opening 32 will fall on the water guiding inclined surface 246. Since the water guiding inclined surface 246 inclines from the outer side plate 241 towards the inside of the spraying seat 24 from top to bottom, the water flow will be concentrated to the inside of the spraying seat 24, that is, the position where the water outlet 245 is located, and finally discharged from the water outlet 245 onto the plate body.

[0057] The deflector 247 is vertically arranged in the middle of the spray seat 24. The bottom of the water guiding inclined surface 246 and the bottom of the deflector 247 enclose the water outlet 245. Water flows between the water guiding inclined surface 246 and the deflector 247. The water outlet 245 is located on one side of the top of the water flow channel close to the heat exchange plate 12 to ensure that the water flow can directly flow to the surface of the heat exchange plate 12.

[0058] See Figure 9 , a partition strip 25 is arranged 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 to prevent the water flow from entering the partition strip 25. A receiving groove 251 is arranged on one side of the partition strip 25 close to the heat exchange member 1. The flowing water ice maker evaporator further includes an abutting strip 5. One side of the abutting strip 5 is fixed in the receiving groove 251, and the other side of the abutting strip 5 can abut against the surface of the heat exchange plate 12. The abutting strip 5 is made of silica gel material, which can improve the sealing degree between the partition plate 22 and the heat exchange plate 12. The receiving groove 251 can press the abutting strip 5 against the surface of the heat exchange plate 12, so as to achieve the effect of sealing isolation. The water flow can only flow in the same ice-making channel 21 and will not seep into other ice-making channels 21.

[0059] In addition, see Figure 10 , in order to fix the abutting strip 5, an installation groove 252 is arranged on one side of the partition strip 25 far from the heat exchange plate 12. A fixing through hole 2521 is arranged in the installation groove 252. A fixing hole 51 is arranged on the abutting strip 5, and a locking hole 15 is arranged on the heat exchange member 1. The positions of the fixing through hole 2521, the fixing hole 51 and the locking hole 15 correspond in sequence. By using fasteners such as screws, the abutting strip 5 can be fixed to the heat exchange plate 12 through the fixing through hole 2521, the fixing hole 51 and the locking hole 15. Moreover, the partition strip 25 can separate the water flow and prevent the water flow from entering the partition strip 25, thus preventing the fasteners from rusting.

[0060] An embodiment of the present invention also discloses an ice-making device (not shown in the drawings), which includes the evaporator of the flowing water ice-making device as described above. The evaporator of the flowing water ice-making device is provided with a heat exchange member 1, a forming member 2, and a spraying member 3. A plurality of ice lattice grooves 4 are formed between the forming member 2 and the heat exchange member 1. The heat exchange member 1 can exchange heat with water flow through the ice lattice grooves 4, so that water freezes into ice cubes in the ice lattice grooves 4. Wherein the number of the forming members 2 is at least two, and the two forming members 2 are respectively located on both sides of the heat exchange member 1, so as to be able to exchange heat on both sides of the evaporator. The two forming members 2 can make ice simultaneously, and can utilize the cold quantity on both sides of the heat exchange member 1. Moreover, a water spraying port 32 is provided at the bottom of the spraying member 3, and the distribution position of the water spraying port 32 corresponds to the positions of the two forming members 2. The water flow sprayed out from the water spraying port 32 can flow into the inner wall surface of the ice lattice groove 4 through the ice-making channel 21. The distance between the water flow and the heat exchange member 1 is relatively close, and the heat exchange member 1 can directly cool the water flow. Compared with the traditional structural method in which the water flow is cooled outside the ice lattice groove 4, it has higher heat transfer efficiency and ice-making efficiency.

[0061] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
