DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 9As shown, the water cooling structure in one embodiment of the utility model comprises a hollow water cooling plate 1, the interior of the water cooling plate 1 is provided with a loading plate 103, the loading plate 103 is also hollow, the interior of the loading plate 103 is connected with the interior of the water cooling plate 1, and the substrate is placed on the loading plate 103 for evaporation. An inlet pipe 4 and an outlet pipe 5 for circulating cold liquid are arranged on one end surface of the water cooling plate 1, the inlet pipe 4 is used to input cold liquid, and the outlet pipe 5 is used to output cold liquid, and the cold liquid circulates in the hollow water cooling plate 1 to achieve cooling of the water cooling plate 1, and the temperature heat is conducted to the loading plate 103, thereby achieving cooling of the loading plate 103.

[0032] like Figure 1 to Figure 3 As shown, the water cooling plate 1 is provided with a second connecting ear 102 and a symmetrically arranged first connecting ear 101, the water inlet pipe 4 and the water outlet pipe 5 are installed on the second connecting ear 102, and the first connecting ear 101 is provided with a first mounting hole 1011, a screw 6 is passed through the first mounting hole 1011, and a plurality of nuts 7 are threadedly connected to the screw 6, and the end of the screw 6 away from the water cooling plate 1 is fixedly connected to the mounting plate 8 through the nut 7. That is, after the screw 6 passes through the first mounting hole 1011, the screw 6 and the water cooling plate 1 are fixed by a nut 7, and then a nut 7 is threadedly connected to the upper shell 2, and the mounting plate 8 is placed, and the second nut 7 is threadedly connected to the mounting plate 8, and the mounting plate 8 is fixed by two nuts 7. The water cooling plate 1 is fixed to the evaporation machine through the mounting plate 8.

[0033] Figure 1 , Figure 5 , Figure 6 As shown, a plurality of heat exchange fins 9 are fixedly connected to the side wall of the water cooling plate 1, and the plurality of heat exchange fins 9 enable the cold liquid to flow in an S shape in the water cooling plate 1. The end of the convex portion 901 away from the inner side wall of the water cooling plate 1 is rounded to reduce the resistance to the cold liquid flow caused by the end of the convex portion 901 away from the inner side wall of the water cooling plate 1. That is, two adjacent heat exchange fins 9 are fixed on two side surfaces respectively, and there is a gap for the cold liquid to flow between the end of the heat exchange fin 9 away from the inner side surface of the water cooling plate 1 and the opposite side surface, so that the cold liquid flows in an S shape in the water cooling plate 1. At the same flow rate, the speed of the cold liquid flowing inside the water cooling plate 1 is reduced, the contact time between the cold liquid and the water cooling plate 1 is increased, and the heat transfer time between the cold liquid and the water cooling plate 1 is increased, which is more conducive to the transfer of heat. At the same time, the temperature of the water cooling plate 1 can be more evenly distributed, reducing thermal stress.

[0034] like Figure 6 , Fig. 9As shown, since the heat exchange fin 9 is arc-shaped, when the cooling liquid contacts the contact surface of the heat exchange fin 9, the impact force of the cooling liquid flow on the heat exchange fin 9 can be reduced. In addition, when the cooling liquid contacts one end of the arc-shaped heat exchange fin 9, the cooling liquid is blocked by the heat exchange fin 9, and the cooling liquid is forced to turn, and the inner wall of the heat exchange fin 9 and the cooling liquid generate friction, which causes the flow rate of the cooling liquid near the inner wall of the water cooling plate 1 to be further slowed down.

[0035] like Figure 6 , Fig. 9 As shown, a plurality of convex portions 901 are provided on the contact surface between the heat exchange fin 9 and the water flow, and the plurality of convex portions 901 form a wavy pattern on the contact surface between the heat exchange fin 9 and the water flow. When the cold liquid passes through the contact surface with the wavy pattern, the friction between the cold liquid and the contact surface with the wavy pattern is further increased, thereby slowing down the speed at which the cold liquid flows on the inner wall of the water cooling plate 1. Generally, the length of the convex portion 901 is 0.5 cm to 1.2 cm.

[0036] By arranging heat exchange fins 9 inside the water-cooled disk 1, the flow rate of the cold liquid is reduced, thereby increasing the heat exchange time between the cold liquid and the water-cooled disk 1. After the heat exchange fins 9 exchange heat with the cold liquid, the heat exchange fins 9 can exchange heat with the water-cooled disk 1, thereby increasing the contact area between the water-cooled disk 1 and the cold liquid to a certain extent. Therefore, at the same flow rate, the heat dissipation effect of the water-cooled disk 1 is stronger and the heat dissipation is more uniform.

[0037] As a further improvement of the present invention: In order to reduce the use cost of the evaporation machine during use, generally, the evaporation machine uses tap water or water used in other processes as a cooling medium during use. However, if this type of water is used as a cooling medium for a long time, it is easy to cause dirt to adhere to the inner wall of the water-cooled plate 1, thereby affecting the heat exchange efficiency of the water-cooled plate 1.

[0038] like Figure 3 to Figure 8 The water cooling plate 1 shown includes an upper shell 2 and a lower shell 3, and the upper shell 2 and the lower shell 3 form a hollow cavity for the flow of cooling liquid. The heat exchange fins 9 are fixedly connected to the lower shell 3. That is, the water cooling plate 1 is composed of an upper shell 2 and a lower shell 3, and the upper shell 2 and the lower shell 3 can be disassembled, so that it is convenient to clean the inner wall of the upper shell 2 and the lower shell 3. It is convenient to regularly clean the dirt on the inner wall of the water cooling plate 1, and to avoid dirt adhering to the inner wall of the water cooling plate 1 as much as possible to affect the cooling efficiency of the water cooling structure.

[0039] Specifically, the water cooling plate 1 is provided with two symmetrically arranged first connecting ears 101 and two symmetrically arranged second connecting ears 102, and the screw rod 6 passes through the first mounting hole 1011 and is threadedly connected with the nut 7 to achieve the fixation of the upper shell 2 and the lower shell 3. The lower shell 3 is fixedly connected with a plurality of connecting columns 301, and the connecting columns 301 are provided with threaded holes. The upper shell 2 is provided with through holes 201 matching the connecting columns 301, and the through holes 201 are provided with bolts 10, which pass through the through holes 201 and are threadedly connected with the threaded holes to fasten the upper shell 2 and the lower shell 3. The upper shell 2 and the lower shell 3 are fixed in multiple directions to ensure the tightness of the upper shell 2 and the lower shell 3.

[0040] like Figure 7-Figure 8 As shown, in order to further enhance the sealing performance of the connection between the upper shell 2 and the lower shell 3, a connecting portion 202 is fixedly connected to the lower end of the upper shell 2, and a groove 302 matching the connecting portion 202 is provided on the lower shell 3, and the connecting portion 202 and the connecting column 301 are interference fit. The sealing performance is enhanced by the matching of the connecting portion 202 and the connecting column 301.

[0041] like Figure 8 As shown, a sealing ring 11 is fixedly connected to the side wall of the groove 302. The sealing ring 11 is made of rubber material. The sealing ring 11 reduces the gap between the outer wall of the connecting part 202 and the connecting column 301, thereby improving the sealing effect of the upper shell 2 and the lower shell 3.

[0042] By dividing the water cooling plate 1 into an upper shell 2 and a lower shell 3, it is convenient to regularly clean the inner walls of the upper shell 2 and the lower shell 3, thereby avoiding the situation where dirt affects the heat exchange effect as much as possible.

[0043] When the utility model is in use, the cold liquid is transported to the inside of the water cooling disk 1 through the water inlet pipe 4, and the cold liquid contacts the heat exchange fins 9 and the inner wall of the water cooling disk 1, performs heat exchange with the heat exchange fins 9 and the water cooling disk 1, and dissipates heat from the water cooling disk 1 and the loading disk 103. The cold liquid flows in the water cooling disk 1 in an S shape, and when the pressure is equal, the speed of the cold liquid flowing in the water cooling disk 1 is slowed down, thereby improving the efficiency of heat exchange between the cold liquid and the water cooling disk 1. The cold liquid finally flows out from the water outlet pipe 5.

[0044] After the water cooling plate 1 has been used for a period of time, the dirt inside it affects the heat exchange efficiency of the water cooling plate 1. When the water cooling plate 1 needs to be cleaned regularly, first unscrew the nut 7 at the uppermost end of the screw 6, separate the water cooling plate 1 and the mounting plate 8, that is, remove the water cooling plate 1 from the evaporation machine, then remove all the nuts 7 on the screw 6, and then unscrew the bolt 10, the upper shell 2 and the lower shell 3 can be separated, and the interior of the upper shell 2 and the lower shell 3 can be cleaned. When assembling, firstly engage the upper shell 2 and the lower shell 3 through the connecting part 202 and the connecting column 301, then screw the bolt 10 into the threaded hole on the lower shell 3, insert the screw 6 into the first connecting ear 101, and fix the upper shell 2 and the lower shell 3 through a nut 7 and the screw 6, and finally fix the screw 6 on the mounting plate 8 through two nuts 7.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
