[0014] DETAILED DESCRIPTION

[0015] The utility model will be further described below in combination with the drawings.

[0016] The ice-making machine evaporator of the utility model, like Figure 1 and Figure 2 ​As shown in the figure, it comprises an evaporation main pipe body 1 and an ice making column 2, one end of the evaporation main pipe body 1 is formed with an input end 101, and the other end of the evaporation main pipe body 1 is formed with an output end 102, the refrigerant is input into the evaporation main pipe body 1 from the input end 101, and then the refrigerant is discharged through the output end 102, as shown in the figure Figure 1 As shown in the figure, the evaporation main pipe body 1 is arranged in a curved manner in the horizontal plane. Figure 2 As shown in the figure, the evaporation main pipe body 1 comprises a pipe bottom shell 11 and a pipe top 12, the pipe top 12 is arranged on the pipe bottom shell 11, as shown in the figure Figure 3 As shown in the figure, the cross section of the pipe bottom shell 11 is in an arc shape, as shown in the figure Figure 2 As shown in the figure, the pipe top 12 is formed with a vent hole 1201, and the lower end of the ice making column 2 is formed with a cup mouth 201, that is, in the visual direction of Figure 2 , the ice making column 2 is in an inverted cup structure, and the cup mouth 201 is connected to the vent hole 1201, as shown in the figure Figure 1 As shown in the figure, the ice making column 2 is arranged along the evaporation main pipe body 1. In actual application, the ice maker evaporator needs to be used in an inverted manner, that is, the ice making column 2 is located on the lower side of the evaporation main pipe body 1, and the evaporation main pipe body 1 is arranged horizontally, so that the ice making column 2 can be immersed in water.

[0017] As shown in the figure Figure 2 and Figure 3 The ice maker evaporator of the utility model further comprises a flow channel partition plate 3, the flow channel partition plate 3 comprises a partition plate body 30, an air inlet guide arc plate part 31 and an air outlet guide arc plate part 32, the ice making column 2 is formed with an ice making column air inlet flow channel 2001 and an ice making column air outlet flow channel 2002, and the partition plate body 30 is arranged between the ice making column air inlet flow channel 2001 and the ice making column air outlet flow channel 2002, that is, in the visual direction of Figure 2 , the partition plate body 30 divides the inner cavity of the ice making column 2 into two parts (the ice making column air inlet flow channel 2001 and the ice making column air outlet flow channel 2002). As shown in the figure Figure 2 The air inlet guide arc plate part 31 is arranged in the pipe bottom shell 11, the upper end of the air inlet guide arc plate part 31 is connected to the lower end of the partition plate body 30 in an integrated manner, so that the flow channel partition plate 3 also divides the vent hole 1201 into two parts, the air inlet guide arc plate part 31 is arranged in a curved manner from top to bottom to the side of the ice making column air inlet flow channel 2001, and in the visual direction of Figure 2 , if the refrigerant is conveyed from left to right in the evaporation main pipe body 1, then the air inlet guide arc plate part 31 is arranged in a curved manner from top to bottom to the left, the air outlet guide arc plate part 32 is arranged in the upper end part of the ice making column 2, the lower end of the air outlet guide arc plate part 32 is connected to the upper end of the partition plate body 30 in an integrated manner, the air outlet guide arc plate part 32 is arranged in a curved manner from bottom to top to the side of the ice making column air outlet flow channel 2002, and the air outlet guide arc plate part 32 and the inner top part of the ice making column 2 form an air passing opening 2003.

[0018] As shown in the figure Figure 2As shown, the refrigerant is delivered from left to right. When the refrigerant reaches the inlet guide arc plate 31, since the inlet guide arc plate 31 is curved from top to bottom and then to the left, the refrigerant can smoothly turn upward under the guidance of the inlet guide arc plate 31. The refrigerant flows upward through the vent 1201 (on the left side of the flow channel partition 3) to the ice column inlet channel 2001, and then enters the upper end of the ice column outlet channel 2002 through the aforementioned vent 2003. During this process, since the outlet guide arc plate 32 moves from bottom to top towards the ice column... The outlet airflow channel 2002 is laterally curved, allowing the outlet guide arc plate 32 to guide the refrigerant flow in a reverse direction (approximately 180°), resulting in a smooth and gentle refrigerant flow. The refrigerant then flows downwards along the ice-making column outlet airflow channel 2002 back to the vent 1201 (on the right side of the flow channel baffle 3), and then flows back to the evaporator main body 1. Because the refrigerant flows from the relatively small cross-sectional area of ​​the ice-making column outlet airflow channel 2002 back to the larger cross-sectional area of ​​the evaporator main body 1, the turbulence at the angle between the right side of the flow channel baffle 3 and the bottom shell 11 is relatively mild. Figure 1 As shown, since the ice-making columns 2 are distributed along the main evaporation body 1, the refrigerant passes through each ice-making column 2 in sequence, and finally the refrigerant is output through the output end 102. As can be seen from the above, compared with the prior art, this utility model can reduce the refrigerant flow resistance, which is conducive to the good operation of the refrigeration system and thus helps to improve the refrigeration effect.

[0019] Furthermore, such as Figure 2 As shown, the baffle body 30 is inclined toward the ice column outlet channel 2002. That is to say, the lower end of the baffle body 30 is located to the left of the upper end of the baffle body 30. Therefore, when the refrigerant flows from the evaporator main body 1 into the ice column inlet channel 2001, the inclination of the baffle body 30 toward the ice column outlet channel 2002 reduces the refrigerant reversal amplitude, which is conducive to the smooth flow of the refrigerant.

[0020] Furthermore, such as Figure 2 and Figure 3 As shown, the top 12 of the tube has a flat plate structure, so the vent 1201 is formed on a flat surface. Welding the edge of the vent 1201 to the cup opening 201 is relatively simple. If the top 12 of the tube were curved, the cup opening 201 would require a more complex cut, making welding more difficult. The top 12 of the tube can be welded to the bottom shell 11. Figure 2 As shown, specifically, the angle between the baffle body 30 and the top of the tube 12 is 86° to 88°.

[0021] Furthermore, such as Figure 2 and Figure 3As shown, the cup mouth 201 is formed with an outward turning edge 22, which is attached to the upper side of the edge portion of the air passage 1201, and is sealingly welded with the pipe top portion 12. The outward turning edge 22 is beneficial to increase the structural strength of the cup mouth 201, and avoid the deformation of the cup mouth 201. Moreover, the outward turning edge 22 is attached to the upper side of the edge portion of the air passage 1201 and then welded, so that the welding slag is not easy to enter into the evaporation pipe body 1, and is beneficial to the welding stability and sealing property of the cup mouth 201 and the edge portion of the air passage 1201. The prior art is to insert the lower end of the ice making column into the air passage and then weld, because there is a large gap between the lower end of the ice making column and the air passage (so that the lower end of the ice making column is easy to be inserted into the air passage), the welding slag is easy to enter into the evaporation pipe body 1, and the welding sealing reliability is insufficient due to the above gap.

[0022] Further, as shown in Figure 2 and Figure 3 , the upper end of the ice making column 2 is formed with a ball cover portion 21, which is a semi-spherical shell, and the air passage 2003 is arranged in the ball cover portion 21, so that the air passage 2003 is formed between the inner top of the ball cover portion 21 and the air outlet flow guide arc plate portion 32. As shown in Figure 2 , when the refrigerant is diverted from the ice making column air inlet flow channel 2001 to the ice making column air outlet flow channel 2002, the inner wall of the ball cover portion 21 can guide the diversion flow of the refrigerant, and reduce the turbulence. As shown in Figure 2 , the ice making column 2 includes a cylinder portion 20, the ball cover portion 21 is integrally arranged on the upper end of the cylinder portion 20, the outward turning edge 22 is formed on the lower end of the cylinder portion 20, and the partition plate body 30 is arranged in the cylinder portion 20.
