[0047] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0048] Combine Figures 1 to 17 According to an embodiment of the present invention, the ice-making device 100 includes: a first ice-making element 10 and a second ice-making element 20, the first ice-making element 10 has a first ice tray 101, the second ice-making element 20 has a second ice tray 201, and the second ice-making element 20 is connected to the first ice-making element 10; wherein, the ice-making device 100 also includes a heat exchange flow channel 30, the heat exchange flow channel 30 is used for a heat exchange medium to pass through the first ice-making element 10 and the second ice-making element 20 to provide cooling to produce ice cubes in the first ice tray 101 and the second ice tray 201, and at least a portion of the heat exchange flow channel 30 is arranged between the first ice-making element 10 and the second ice-making element 20.

[0049] Specifically, the ice-making device 100 includes two ice-making elements and a heat exchange channel 30. Both ice-making elements are equipped with multiple ice trays. The heat exchange medium in the heat exchange channel 30 cools both ice-making elements, increasing the number of ice cubes produced. At least a portion of the heat exchange channel 30 is located between the first ice-making element 10 and the second ice-making element 20. This allows the heat exchange medium in the heat exchange channel 30 to exchange heat with both the first ice-making element 10 and the second ice-making element 20 simultaneously, improving heat exchange efficiency. It also reduces the space occupied by the heat exchange channel 30, improving space utilization and facilitating space layout.

[0050] According to the ice-making device 100 of the embodiment of the present invention, by disposing at least a portion of the heat exchange channel 30 between the first ice-making element 10 and the second ice-making element 20, the heat exchange efficiency can be improved and the space occupied can be reduced.

[0051] It should be noted that at least a portion of the heat exchange channel 30 is disposed between the first ice-making element 10 and the second ice-making element 20. Alternatively, a portion of the heat exchange channel 30, such as a small portion or a large portion, may be disposed between the first ice-making element 10 and the second ice-making element 20. Alternatively, the entire heat exchange channel 30 may be disposed between the first ice-making element 10 and the second ice-making element 20.

[0052] Combine Figure 1 and Figure 6 In some embodiments of the present invention, the first ice-making elements 10 and the second ice-making elements 20 are arranged along a first direction, with the opening of the first ice tray 101 facing away from the second ice-making element 20, and the opening of the second ice tray 201 facing away from the first ice-making element 10. In this way, the first ice-making elements 10 and the second ice tray 20 can be connected so as to face away from each other, with the openings of the multiple first ice trays 101 and the multiple second ice trays 201 all facing outward, saving space while increasing ice production. In other words, the back-to-back installation of the ice-making device 100 saves space, reduces exposed area, and improves heat transfer efficiency.

[0053] Combine Figure 2 and Figure 3In some embodiments of the present invention, the first ice-making element 10 includes a plurality of first ice trays 101 distributed along a second direction, and the heat exchange channel 30 includes a first sub-channel 310. The first sub-channel 310 is disposed between the first ice-making element 10 and the second ice-making element 20. When the heat exchange medium flows through the first sub-channel 310, a cooling effect can be achieved for both the first ice-making element 10 and the second ice-making element 20, thereby improving cooling efficiency. Specifically, in the related art, an ice-making device generally includes an ice tray and a heat exchanger. The ice tray is provided with a plurality of ice trays. One side of the heat exchanger is close to the back of the ice tray or away from the side of the ice tray opening. During operation, the cold air of the refrigerant in the heat exchanger approaches the ice tray to form ice, resulting in the loss of cold energy on the other side of the heat exchanger. In addition, in order to improve the cooling effect on the ice tray, the size of the heat exchanger needs to match the ice tray, resulting in a large occupied area. In the solution of the present application, the first ice-making element 10 and the second ice-making element 20 are arranged back-to-back, and the heat exchange channel 30 is disposed between the first ice-making element 10 and the second ice-making element 20. The heat exchange channel 30 is positioned on opposite sides of the first ice-making element 10 and the second ice-making element 20, respectively. This reduces energy loss and improves heat exchange efficiency. Furthermore, ice trays are provided on opposite sides of the ice-making device 100, which facilitates structural compactness. Furthermore, the first ice-making element 10 and the second ice-making element 20 share the first sub-channel 310, which simplifies the structure and facilitates space layout.

[0054] Further, combined with Figure 2 and Figure 7 The heat exchange channel 30 also includes a second sub-channel 320, which is arranged between adjacent first ice trays 101, with the second direction being perpendicular to the first direction. That is, the first sub-channel 310 of the heat exchange channel 30 can flow between the first ice-making element 10 and the second ice-making element 20, thereby providing a heat exchange effect on the ice trays in the first direction. The second sub-channel 320 of the heat exchange channel 30 can flow between adjacent first ice trays 101, thereby providing a heat exchange effect on the first ice trays 101 in the second direction, which is the distribution direction of the multiple first ice trays 101. Therefore, the heat exchange channel 30 includes a first sub-channel 310 that cools the first ice trays 101 in the first direction and a second sub-channel 320 that cools the first ice trays 101 in the second direction. The first sub-channel 310 and the second sub-channel 320 flow around the first ice tray 101 in two mutually perpendicular directions, forming a three-dimensional heat exchange channel 30. Therefore, the heat exchange channel 30 can exchange heat with the bottom wall of the first ice tray 101 and the side wall of the first ice tray 101, thereby accelerating the formation speed of ice cubes in the first ice tray 101 and improving ice making efficiency.

[0055] Furthermore, combined Figure 1 and Figure 6In some embodiments of the present invention, the second ice-making element 20 includes a plurality of second ice trays 201 distributed along a second direction, and the heat exchange channel 30 further includes a third sub-channel 330, which is disposed between adjacent second ice trays 201. Specifically, the first sub-channel 310 of the heat exchange channel 30 can flow between the first ice-making element 10 and the second ice-making element 20, thereby providing heat exchange for the second ice trays 201 in the first direction. The third sub-channel 330 of the heat exchange channel 30 can flow between adjacent second ice trays 201, thereby providing heat exchange for the second ice trays 201 in the second direction, which is the distribution direction of the plurality of second ice trays 201. Therefore, the heat exchange channel 30 includes the first sub-channel 310, which cools the second ice trays 201 in the first direction, and the third sub-channel 330, which cools the second ice trays 201 in the second direction. The first and third sub-channels 310, 330 flow around the second ice trays 201 in two mutually perpendicular directions, forming a three-dimensional heat exchange channel. Therefore, the heat exchange channel 30 can exchange heat with the bottom wall of the second ice tray 201 and the side wall of the second ice tray 201, thereby accelerating the formation speed of ice cubes in the second ice tray 201 and improving ice making efficiency.

[0056] Combine Figure 7 and Figure 8 In some embodiments of the present invention, the ice-making device 100 further includes a first partition 40, which includes a first sub-plate 41. The first sub-plate 41 extends into the second sub-channel 320 and allows the fluid in the second sub-channel 320 to circulate in a circuitous manner. In combination with the above, since the second sub-channel 320 is disposed between adjacent first ice cube trays 101, the heat exchange medium in the second sub-channel 320 can simultaneously cool two adjacent ice cube trays. By disposing the first sub-plate 41 in the second sub-channel 320, the second sub-channel 320 can be separated, making the second sub-channel 320 a circuitous flow channel. In this way, when the heat exchange medium circulates, see Figure 2 and Figure 7 The liquid may first flow through a first ice tray 101, then bypass the first sub-plate 41 and flow through another adjacent first ice tray 101, and then flow in sequence between the multiple first ice trays 101 distributed along the second direction. This can increase the flow path of the second sub-channel 320, increase the contact time between the second sub-channel 320 and the ice tray, and help improve the heat exchange efficiency.

[0057] The first partition plate 40 further includes a second sub-plate 42, which extends into the third sub-channel 330 and allows the fluid in the third sub-channel 330 to circulate in a circuitous manner. Combined with the above, since the third sub-channel 330 is disposed between adjacent second ice cube trays 201, the heat exchange medium in the third sub-channel 330 can simultaneously cool two adjacent ice cube trays. By disposing the second sub-plate 42 in the third sub-channel 330, the third sub-channel 330 can be separated, making the third sub-channel 330 a circuitous flow channel. Thus, when the heat exchange medium circulates, Figure 2 The liquid may first flow through a second ice tray 201, then bypass the second sub-plate 42 and flow through another adjacent second ice tray 201, and then flow in sequence between the plurality of second ice trays 201 distributed along the second direction. This can extend the flow path of the third sub-channel 330, increase the contact time between the third sub-channel 330 and the ice tray, and help improve the heat exchange efficiency.

[0058] Combine Figure 2 In some embodiments of the present invention, the second sub-channel 320 and the third sub-channel 330 are staggered along the first direction, the first sub-plate 41 is provided on the first ice-making element 10, and the second sub-plate 42 is provided on the second ice-making element 20. Thus, when the heat exchange medium flows through the heat exchange channel 30, it can first flow through the second sub-channel 320 and then flow through the third sub-channel 330, circulating and circulating between the second sub-channel 320 and the third sub-channel 330, so that the heat exchange medium can fully contact the first ice tray 101 and the second ice tray 201, which is beneficial to improving the heat exchange effect.

[0059] Combine Figure 9 In order to simplify the assembly of the ice-making structure, in some other embodiments of the present invention, the second sub-channel 320 and the third sub-channel 330 are opposite to each other along the first direction, and the first sub-plate 41 and the second sub-plate 42 are integrated into the same plate body. In this way, during assembly, the integrated plate body of the first sub-plate 41 and the second sub-plate 42 can be directly installed between the first ice-making element 10 and the second ice-making element 20, and the second sub-channel 320 and the third sub-channel 330 are arranged opposite to each other. In actual application, combined with Figure 7 Part of the heat exchange medium can flow to the second sub-channel 320 to cool the first ice tray 101, and part can flow to the third sub-channel 330 to cool the second ice tray 201, which is beneficial to simultaneously improve the cooling efficiency of the first ice-making element 10 and the second ice-making element 20.

[0060] Furthermore, a third groove 15 with an opening facing the second ice-making element 20 is provided on the back side of the first ice-making element 10, and a portion of the second sub-plate 42 extends into the third groove 15, so that a circuitous flow channel is formed in the second sub-channel 320; a fourth groove 25 with an opening facing the first ice-making element 10 is provided on the back side of the second ice-making element 20, and a portion of the first sub-plate 41 extends into the fourth groove 25, so that a circuitous flow channel is formed in the third sub-channel 330.

[0061] Combine Figure 1 In some embodiments of the present invention, the inlet 110 and outlet 120 of the heat exchange channel 30 are located at the same end of the ice-making device 100. The ice-making device 100 further includes a second partition 43 that separates the first sub-channel 310 along the third direction to form an inlet channel 301 and an outlet channel 302. One end of the inlet channel 301 is connected to the inlet 110, one end of the outlet channel 302 is connected to the other end of the inlet channel 301, and the other end of the outlet channel 302 is connected to the outlet 120.

[0062] Specifically, the second partition 43 can separate the first sub-channel 310 into an inlet channel 301 and an outlet channel 302. This allows the heat exchange medium to enter the first sub-channel 310 from the inlet channel 301, circulate through the inlet channel 301, then enter the outlet channel 302 before exiting through the outlet 120. This extends the flow path of the first sub-channel 310, increasing the contact time between the first sub-channel 310 and the first and second ice-making elements 10 and 20, thereby facilitating sufficient heat exchange and improving heat exchange efficiency. Furthermore, the inlet 110 and outlet 120 of the heat exchange channel 30 are located at the same end of the ice-making device 100, extending the heat exchange medium's circulation distance. The heat exchange medium can enter from the inlet, flow through the inlet channel 301 and the outlet channel 302, and then exit through the outlet 120.

[0063] Optionally, combined Figure 9 The ice-making device 100 also includes an inlet pipe 111 and an outlet pipe 121. One end of the inlet pipe 111 is connected to the first ice-making element 10, and the other end is configured with an inlet and outlet 110, which can facilitate the heat exchange medium to enter the heat exchange channel 30 and facilitate pipeline connection. One end of the outlet pipe 121 is connected to the first ice-making element 10, and the other end is configured with an outlet 120, which can facilitate the heat exchange medium to flow out of the heat exchange channel 30 and facilitate pipeline connection.

[0064] Combine Figure 4 and Figure 5 In some embodiments of the present invention, the first ice-making element 10 further includes a first rib 11. The first rib 11 is disposed between adjacent first ice trays 101 and separates a second sub-channel 320 communicating with the liquid inlet channel 301 and a second sub-channel 320 communicating with the liquid outlet channel 302 between the adjacent first ice trays 101. Thus, the first rib 11 can separate the second sub-channel 320 into the liquid inlet channel 301 and the liquid outlet channel 302, allowing the heat exchange medium in the second sub-channel 320 to flow from the liquid inlet channel 301 to the liquid outlet channel 302, thereby optimizing the flow path of the heat exchange medium within the second sub-channel 320.

[0065] Combine Figure 4In some embodiments of the present invention, the second ice-making element 20 further includes a second rib 22. The second rib 22 is disposed between adjacent second ice trays 201 and separates a third sub-channel 330 communicating with the liquid inlet channel 301 and a third sub-channel 330 communicating with the liquid outlet channel 302 between the adjacent second ice trays 201. Thus, the first rib 11 can separate the third sub-channel 330 into the liquid inlet channel 301 and the liquid outlet channel 302. This allows the heat exchange medium in the third sub-channel 330 to flow from the liquid inlet channel 301 to the liquid outlet channel 302, thereby optimizing the flow path of the heat exchange medium within the third sub-channel 330.

[0066] Combine Figure 10 The bottom surface of the first ice-making element 10 is provided with a recess 12, the second ice-making element 20 covers the recess 12 and forms a first sub-channel 310, and the second partition 43 is provided in the recess 12 of the first ice-making element 10. Therefore, after the first ice-making element 10 and the second ice-making element 20 are assembled, the first sub-channel 310 can be directly formed, and the second partition 43 is provided in the recess 12, which can directly separate the liquid inlet channel 301 and the liquid outlet channel 302 in the first sub-channel 310, wherein the depth of the recess 12 can be the depth of the first sub-channel 310, and the second partition 43 separates the recess 12 and the space after the second ice-making element 20 covers the recess 12 into the liquid inlet channel 301 and the liquid outlet channel 302, which is conducive to simplifying the structure and improving the structural compactness of the ice-making device 100.

[0067] With reference to the figures, in other embodiments of the present invention, the ice-making device 100 further includes an annular rib 44, which connects the first ice-making element 10 and the second ice-making element 20 and forms a first sub-flow channel 310 between the first ice-making element 10 and the second ice-making element 20. The second partition 43 connects the annular rib 44 and is disposed inside the annular rib 44. In other words, the annular rib 44, when connected to the first ice-making element 10 and the second ice-making element 20, forms the first sub-flow channel 310. Specifically, the annular rib 44 can have a certain thickness along the first direction, which is the depth of the first sub-channel 310. The annular rib 44 includes a frame 441 and a dividing rib 442. The frame 441 is connected to the first ice-making component 10 and the second ice-making component 20. The dividing rib 442 extends along the second direction. The end of the dividing rib 442 is connected to one end of the frame 441 close to the inlet 110 and the outlet 120 to achieve separation within the frame 441. When the annular rib 44 cooperates with the first ice-making component 10 and the second ice-making component 20, a liquid inlet channel 301 and a liquid outlet channel 302 can be formed.

[0068] Combine Figure 4 and Figure 5The first ice-making element 10 is provided with a plurality of first sub-plates 41, which are spaced apart along the second direction and two of which are spaced apart along the third direction. A first rib 11 is provided between two adjacent first sub-plates 41 along the third direction. During assembly, the second rib 22 of the second ice-making element 20 extends between two adjacent first sub-plates 41 along the third direction and cooperates with the first rib 11 to separate the first sub-flow channel 310 into the liquid inlet channel 301 and the liquid outlet channel 302. The second ice-making element 20 is provided with a plurality of second sub-plates 42, which are spaced apart along the second direction and two of which are spaced apart along the third direction. A second rib 22 is provided between two adjacent second sub-plates 42 along the third direction.

[0069] Combine Figure 11 In some embodiments of the present invention, the first ice-making element 10 and the second ice-making element 20 are connected along a third direction, and the opening of the first ice tray 101 and the opening of the second ice tray 201 face the same direction. In other words, the first ice-making element 10 and the second ice tray 20 can be connected side by side. Specifically, in some usage scenarios, to conserve space in the first or horizontal direction, the ice-making device 100 can also be arranged longitudinally, for example, by connecting the first ice-making element 10 and the second ice-making element 20 to form two rows of ice trays arranged along the third direction.

[0070] Further, combined with Figure 12 and Figure 13 In some embodiments of the present invention, the ice-making device 100 further includes a cover plate 50, which faces away from the opening of the first ice tray 101 and the second ice tray 201. The heat exchange channel 30 includes a fourth sub-channel 340 and a fifth sub-channel 350. The fourth sub-channel 340 is disposed between the cover plate 50 and the first ice-making element 10, and the fifth sub-channel 350 is disposed between the cover plate 50 and the second ice-making element 20. Specifically, the cover plate 50 is disposed on the backside of the first ice-making element 10 and the second ice-making element 20. The fourth sub-channel 340 is disposed between the cover plate 50 and the first ice-making element 10, allowing heat exchange medium to flow through the bottom walls of the plurality of first ice trays 101. The fifth sub-channel 350 is configured between the cover plate 50 and the second ice-making element 20, allowing heat exchange medium to flow through the bottom walls of the plurality of second ice trays 201.

[0071] Further, combined with Figure 15In some embodiments of the present invention, the inlet 110 and outlet 120 of the heat exchange channel 30 are located at the same end of the ice-making device 100. One end of the fourth sub-channel 340 is connected to the inlet 110, one end of the fifth sub-channel 350 is connected to the other end of the fourth sub-channel 340, and the other end of the fifth sub-channel 350 is connected to the outlet 120. Specifically, after entering the fourth sub-channel 340 from the inlet 110, the heat exchange medium first flows through the fourth sub-channel 340 to cool the first ice-making element 10, then enters the fifth sub-channel 350 and flows out of the outlet 120 to cool the second ice-making element 20. This arrangement also extends the flow path of the heat exchange medium, increasing the contact time between the heat exchange medium and the first and second ice-making elements 10, 20, thereby facilitating sufficient heat exchange and improving heat exchange efficiency. In addition, the inlet 110 and outlet 120 of the heat exchange channel 30 are arranged at the same end of the ice-making device 100, which is conducive to extending the circulation distance of the heat exchange medium. The heat exchange medium can enter from the inlet 110, flow through the entire ice-making device 100, and then flow out from the outlet 120.

[0072] Combine Figure 16 In some embodiments of the present invention, the bottom of the first ice-making element 10 is provided with a first recess 13, and the cover plate 50 is provided with a first protrusion 51. This increases the size of the fourth sub-channel 340, allowing more heat exchange medium to flow through and improving heat exchange efficiency. The first recess 13 and the first protrusion 51 are arranged opposite each other along a first direction and form a U-shape, which lengthens the flow path of the fourth sub-channel 340, increasing the contact time between the heat exchange medium and the first ice-making element 10 and improving heat exchange efficiency.

[0073] The fifth sub-channel 350 is located between the cover plate 50 and the second ice-making element 20. The bottom of the first ice-making element 10 is located in the second recess 23. The cover plate 50 is provided with a second protrusion 52, which increases the size of the fifth sub-channel 350, allowing more heat exchange medium to flow through and improving heat exchange efficiency. The second recess 23 and the second protrusion 52 are arranged opposite each other along the first direction and form a U-shape, which extends the flow path of the fifth sub-channel 350, increasing the contact time between the heat exchange medium and the first ice-making element 10 and improving heat exchange efficiency.

[0074] Optionally, combined Figure 16 The ice-making device 100 further includes an inlet pipe 111 and an outlet pipe 121. One end of the inlet pipe 111 is connected to the cover plate 50 or the first protrusion 51, and the other end is configured with an inlet and outlet 110, which can facilitate the heat exchange medium to enter the heat exchange channel 30 and facilitate pipeline connection. One end of the outlet pipe 121 is connected to the cover plate 50 or the second protrusion 52, and the other end is configured with an outlet 120, which can facilitate the heat exchange medium to flow out of the heat exchange channel 30 and facilitate pipeline connection.

[0075] Further, combined with Figure 14In some embodiments of the present invention, the heat exchange channel 30 further includes a sixth sub-channel 360, the first ice-making element 10 includes a plurality of first ice trays 101 distributed along the second direction, the second ice-making element 20 includes a plurality of second ice trays 201 distributed along the second direction, and the sixth sub-channel 360 is arranged between adjacent first ice trays 101 and second ice trays 201. Thus, when the heat exchange medium flows through the sixth sub-channel 360, cooling can be performed between the first ice trays 101 and the second ice trays 201, so that the side walls of the first ice trays 101 and the second ice trays 201 can also exchange heat with the heat exchange medium.

[0076] That is to say, by setting the fourth sub-channel 340 and the sixth sub-channel 360, heat exchange can be performed on the first ice-making element 10 in two directions, that is, heat exchange can be performed on the bottom wall and side wall of the first ice cube tray 101; by setting the fifth sub-channel 350 and the sixth sub-channel 360, heat exchange can be performed on the second ice-making element 20 in two directions, that is, heat exchange can be performed on the bottom wall and side wall of the second ice cube tray 201, so that the heat exchange channel 30 can form a three-dimensional channel in the ice-making device 100, which is beneficial to improve the heat exchange effect and thus improve the ice-making efficiency.

[0077] Furthermore, combined Figure 12 and Figure 16 In some embodiments of the present invention, the cover plate 50 further includes a convex rib 53, which extends into the sixth sub-channel 360. The convex rib 53 separates the sixth sub-channel 360 into a first channel 361 and a second channel 362 along the third direction. The first channel 361 is located between the convex rib 53 and the first ice tray 101, and the second channel 362 is located between the convex rib 53 and the second ice tray 201.

[0078] Alternatively, the rib 53 may extend into the sixth sub-channel 360 to cause the fluid in the sixth sub-channel 360 to circulate in a circuitous manner. That is, the heat exchange medium flowing through the sixth sub-channel 360 may exchange heat with both the first ice tray 101 and the second ice tray 201. For example, the heat exchange medium in the sixth sub-channel 360 may first flow through the sidewall of the first ice tray 101 and then through the sidewall of the second ice tray 201.

[0079] Combine Figure 14 In some embodiments of the present invention, a rib 53 can separate the fourth sub-channel 340 and the fifth sub-channel 350 along the first direction between the first ice-making element 10 and the second ice-making element 20. Specifically, a groove with one end open is formed at the connection between the first ice-making element 10 and the second ice-making element 20. The open end of the groove faces the rib 53. After the cover plate 50 is installed, the rib 53 extends into the groove, and the sixth sub-channel 360 is formed between the protrusion and the inner wall of the groove.

[0080] In some embodiments of the present invention, the first ice-making component 10 and the second ice-making component 20 are integrally constructed to form an ice tray, and the ice tray is welded to the cover plate 50, which helps to simplify the structure of the ice-making device 100 and facilitates manufacturing and assembly.

[0081] In some embodiments of the present invention, the first ice-making element 10 and the second ice-making element 20 are integrally formed.

[0082] In some embodiments of the present invention, the first ice-making element 10 and the second ice-making element 20 are connected by welding.

[0083] The present invention further provides a water dispenser. According to an embodiment of the present invention, the water dispenser includes the aforementioned ice-making device 100. By installing the aforementioned ice-making device 100 within the water dispenser, heat exchange efficiency can be improved, space usage can be reduced, and the compactness of the internal structure of the water dispenser can be improved.

[0084] The ice-making device 100 according to some specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0085] According to the first embodiment of the present invention, the ice-making device 100 comprises two back-to-back connected first ice-making members 10 and second ice-making members 20. The front of the first ice-making member 10 and the second ice-making member 20 are composed of multiple ice trays, and the back is provided with a raised welding surface. This welding surface is surrounded by a circle and there is a partition (i.e., a second partition 43) in the middle. This welding surface is welded to the back of the second ice-making member 20 to form a sealed flow channel. Figure 3 .

[0086] A raised first partition plate 40 and a groove are provided on the back of the first ice-making element 10, and a raised first partition plate 40 and a groove are also provided on the back of the second ice-making element 20. The positions of the two ice trays are staggered, and the first partition plate 40 of the first ice-making element 10 is inserted into the groove of the second ice-making element 20, and the first partition plate 40 of the second ice-making element 20 is inserted into the groove of the first ice-making element 10, forming a three-dimensional flow channel, such as Figure 5 .

[0087] Specifically, a first groove 14 with an opening facing the second ice-making element 20 is provided on the back side of the first ice-making element 10, and a portion of the second sub-plate 42 extends into the first groove 14, so that a circuitous flow channel is formed in the second sub-channel 320; a second groove 24 with an opening facing the first ice-making element 10 is provided on the back side of the second ice-making element 20, and a portion of the first sub-plate 41 extends into the second groove 24, so that a circuitous flow channel is formed in the third sub-channel 330.

[0088] The first sub-plate 41 is arranged adjacent to the second groove 24, and the second sub-plate 42 is arranged adjacent to the first groove 14. After the first ice-making element 10 and the second ice-making element 20 are connected, a second sub-channel 320 and a third sub-channel 330 are formed that are staggered along the first direction.

[0089] Furthermore, in order to reduce the unevenness of manual solder paste application during welding, the welding efficiency is improved and the complexity of the ice tray structure is reduced.

[0090] The present invention also provides a second embodiment of an ice-making device 100. Neither the first ice-making element 10 nor the second ice-making element 20 has a first partition 40 or a raised welding surface on its back. Instead, a composite plate with double-sided solder is added, along with the first partition 40. The edges of the composite plate, the first ice-making element 10, and the second ice-making element 20 are tightly attached together, with the interior cut away to form a flow channel. The first partition 40 is installed in the center of the ice tray's recess and initially secured by a positioning notch. These components are then welded together in a brazing furnace. In other words, the double-sided first partition 40 between the two ice-making elements replaces solder paste, improving welding efficiency. The independent first partition 40 replaces the multiple sub-plates of the previous embodiment, simplifying the structure of the ice-making device 100.

[0091] In summary, according to some embodiments of the ice-making device 100 of the present invention, the first ice-making element 10 and the second ice-making element 20 are installed back-to-back to save space, reduce exposed area, and improve heat transfer efficiency. The first ice-making element 10 and the second ice-making element 20 are welded together to form an internal heat exchange channel 30. This has a simple structure, a reduced number of parts, and direct contact between the heat exchange medium and the ice-making element, shortening the heat transfer path and improving heat transfer efficiency. Furthermore, by providing a first partition 40 in the ice-making device 100, the area of ​​the heat exchange channel 30 is significantly increased, thereby increasing the heat transfer area and improving heat transfer efficiency. The two ice-making elements are welded together to form the heat exchange channel 30. The heat exchange channel 30 is internally provided with a transverse flow channel and a longitudinal flow channel, significantly increasing the heat exchange area.

[0092] Furthermore, to save horizontal space, the ice-making elements can be arranged vertically, forming two rows of ice trays. The present invention also provides a third embodiment of an ice-making device 100, in which two ice-making elements are combined into a single ice tray. A cover plate 50 is provided on the back, with a concave-convex structure. This concave-convex structure, when welded to the first and second ice-making elements 10 and 20, forms the planar fourth and fifth sub-channels 340 and 350, as well as the three-dimensional sixth sub-channel 360. This provides a larger heat exchange area compared to related art solutions that rely solely on planar heat transfer or copper tubes.

[0093] Optionally, the first ice-making element 10 and the second ice-making element 20 in the present application can be made by various processes such as die forging, casting, and CNC.
