[0004] The above-mentioned device adopts a water chamber method for water cooling, and the temperature of the water chamber cannot be controlled, so different PVB films cannot be water-cooled at different temperatures according to needs. In order to solve this problem, an improved PVB film water cooling device is proposed. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a PVB film water cooling device.

[0006] According to the technical solution provided in the embodiment of the present application, a PVB film water cooling device includes a cooling box, a partition, a copper tube, a refrigerator, a first guide roller, a second guide roller, a fan and a film. The cooling box is internally divided into a first cooling chamber and a second cooling chamber. The upper and lower surfaces of the first cooling chamber are both provided with heat sinks a, and the heat sink a is spaced apart from the upper and lower surfaces of the first cooling chamber. The upper and lower surfaces of the first cooling chamber and the second cooling chamber are fixedly connected with a plurality of heat sinks b. The first cooling chamber and the second cooling chamber are provided with a plurality of conductive members spaced apart and staggered in the horizontal direction. The conductive members are used to dissipate heat when the film passes through the heat sink a and the heat sink b.

[0007] In the present invention, further, a vertically fixed partition is provided in the middle of the cooling box, and the partition divides the cooling box into a first cooling chamber and a second cooling chamber, a rectangular through hole is provided in the middle of the partition, and a plurality of equally spaced ventilation holes are provided on the second cooling chamber.

[0008] In the present invention, further, the inner wall of the first cooling chamber is set as a vacuum layer.

[0009] In the present invention, further, one side of the cooling box is set as an inlet, and the other side is set as an outlet. The inlet and outlet are arranged on the same horizontal line, and both are set as rectangular holes.

[0010] In the present invention, further, the heat sink a is a copper tube and a refrigerator, the copper tubes are provided in two groups that are interconnected, and a group of copper tubes is provided on the upper and lower surfaces of the first cooling chamber.

DETAILED DESCRIPTION

[0021] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] like Figure 1 As shown, the present application provides a PVB film water cooling device consisting of a cooling box 1, a first cooling chamber 10, a second cooling chamber 11, ventilation holes 110, a vacuum layer 12, an inlet 13, an outlet 14, a partition 2, a through hole 20, a copper tube 3, a refrigerator 4, a first guide roller 5, a second guide roller 6, a fan 7, a film 8, etc.

[0024] The cooling box 1 is constructed from several welded steel plates of varying sizes. A partition 2 divides the cooling box 1 into two chambers: a first cooling chamber 10 and a second cooling chamber 11. The first cooling chamber 10 is equipped with heat sinks a and b, while the second cooling chamber 11 is equipped with heat sink b. A vacuum layer 12 is provided on the inner wall of the first cooling chamber 10 and on the partitions to prevent the escape of cold air from the first cooling chamber 10. This vacuum layer 12 maintains the temperature within the first cooling chamber 10 to the greatest extent possible. An inlet 13 is located on one side of the cooling box 1, while an outlet 14 is located on the other side. The inlet 13 and outlet 14 are co-located and are rectangular holes. A vertically fixed partition 2 is located in the middle of the cooling box 1. A rectangular through-hole 20 is provided in the middle of the partition 2 to facilitate the passage of the film 8 from the first cooling chamber 10 to the second cooling chamber 11.

[0025] Heat sink a comprises copper tubes 3 and a refrigerator 4. Multiple copper tubes 3 are provided, arranged in two interconnected groups. A group of copper tubes 3 is positioned on each of the upper and lower surfaces of the first cooling chamber 10. The two groups of copper tubes 3 are spaced apart from the first cooling chamber 10, and one side of each group of copper tubes 3 is fixedly connected to the output of the refrigerator 4. When the refrigerator 4 starts running, the coolant in the copper tubes 3 begins to circulate, facilitating heat dissipation.

[0026] Heat sink b is a fan 7. A set of fans 7 is provided on the upper and lower surfaces of each of the first cooling chamber 10 and the second cooling chamber 11. Both sets of fans 7 are arranged in a corresponding manner, with one set of fans 7 being provided between the upper and lower surfaces of the first cooling chamber 10 and the copper tube 3. When fans 7 are activated, the cold air emitted by the copper tube 3 is more evenly distributed in the first cooling chamber 10. After the film 8 passes through the first cooling chamber 10, because coolant flows through the copper tube 3, condensation beads appear on the surface of the copper tube 3. These condensation beads cause the humidity in the first cooling chamber 10 to be high. Even after the film 8 is cooled by the first cooling chamber 10, it remains relatively moist. Therefore, the film 8 needs to be dried by the fans 7 through the second cooling chamber 11. The second cooling chamber 11 is provided with a number of equally spaced ventilation holes 110, which allow the processed water vapor of the film 8 to escape from the ventilation holes 110.

[0027] The conductive members are a first guide roller 5 and a second guide roller 6. Several first guide rollers 5 are provided at intervals and staggered relative to each other, and are located in a first cooling chamber 10. Two second guide rollers 6 are provided and staggered relative to each other, and are located in a second cooling chamber 11. The film 8 passes sequentially through the inlet 13, the first guide roller 5, through the hole 20, and the second guide roller 6 before exiting the outlet 14.

[0028] The above description is merely an illustration of the preferred embodiments of this application and the technical principles employed. Furthermore, the scope of the utility model disclosed in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features. It also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the utility model. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
