[0034] Embodiment 1

[0035] Basically as shown in the accompanying Figure 1 A middle layer condensing sheet 1 includes a condensing sheet body, and the condensing sheet body is provided with a connecting channel 11, and the connecting channel 11 is a cylindrical channel. The inlet and outlet of the connecting channel 11 are trumpet-shaped. The connecting channel 11 extends from the top of the condensing sheet body to the bottom of the condensing sheet.

[0036] As shown in the accompanying Figure 1 In the present embodiment, a protective cylinder 12 is arranged inside the connecting channel 11, and the protective cylinder 12 is a cylindrical cylinder. The protective cylinder 12 is fixedly installed inside the connecting channel 11 in a welding manner. At the same time, the length of the protective cylinder 12 is the same as the length of the connecting channel 11, so that when the protective cylinder 12 is installed inside the connecting channel 11, the top and bottom of the protective cylinder 12 are flush with the top and bottom of the condensing sheet body, respectively. The inner wall of the protective cylinder 12 is also provided with enamel 4, which can protect the inner wall of the protective cylinder 12 and avoid corrosion of the protective cylinder 12.

[0037] As shown in the accompanying Figure 1 In order to make the protective cylinder 12 fit the inlet and outlet of the connecting channel 11, and also to increase the size of the inlet and outlet of the connecting cylinder, the inlet and outlet of the protective cylinder 12 are trumpet-shaped in the present embodiment. The trumpet-shaped mouth of the protective cylinder 12 can facilitate the flow of liquid.

[0038] The following will be further described in detail through specific embodiments: when the middle layer condensing sheet 1 is working, the liquid flows to the top of the middle layer condensing sheet 1, and then the liquid flows to the connecting channel 11 and flows into the inner wall of the protective cylinder 12. The liquid flows to the bottom of the middle layer condensing sheet 1 through the protective cylinder 12.

[0039] Embodiment 2

[0040] The difference between the present embodiment and embodiment 1 is that, asFigure 2 As shown, in this embodiment, to mitigate the impact force on the enamel layer 4 on the inner wall of the protective cylinder 12, the protective cylinder 12 is disposed inside the connecting channel 11, with its top and bottom fixedly connected to the inner wall of the connecting channel 11. Simultaneously, a gap exists between the outer wall of the protective cylinder 12 and the inner wall of the connecting channel 11 at the middle position. By setting this gap, the impact on the enamel 4 disposed on the inner wall of the protective cylinder 12 is further reduced, preventing cracking of the enamel 4.

[0041] Example 3

[0042] This embodiment provides a condenser, such as Figure 3 As shown, the device includes a middle condenser plate 1, a top condenser plate 2, a bottom condenser plate 3, and a sealing gasket 5, as described in Embodiment 1 or Embodiment 2. The top condenser plate 2 is located at the very top. Multiple middle condenser plates 1 are located below the top condenser plate 2 and arranged vertically. The bottom condenser plate 3 is located below the middle condenser plates 1.

[0043] To address the issues of hard contact between the top condenser 2 and the middle condenser 1, hard contact between the upper and lower middle condenser 1 layers, and hard contact between the bottom condenser 3 and the middle condenser 1 layer, this embodiment employs a sealing gasket 5 between the top condenser 2 and the middle condenser 1 layer. This gasket 5 prevents hard contact between the top condenser 2 and the middle condenser 1 layer, and also prevents liquid leakage between them. Similarly, this embodiment also employs a sealing gasket 5 between the middle condenser 1 layers to prevent hard contact between them and to prevent liquid leakage between them. Finally, this embodiment employs a sealing gasket 5 between the bottom condenser 3 and the middle condenser 1 layer to prevent hard contact between them and to prevent liquid leakage between them.

[0044] In this embodiment, the top condenser plate 2, the middle condenser plate 1, and the bottom condenser plate 3 are all disc-shaped. Meanwhile, the sealing gasket 5 is annular to fit the condenser plates. The sealing gasket 5 can be any type of sealing gasket found in the prior art.

[0045] like Figure 4As shown, in order to increase the volume for liquid containment between the top condenser plate 2 and the middle condenser plate 1, this embodiment preferably also provides an annular protrusion on the top of the middle condenser plate 1. The annular protrusion is circular, and its shape and size are adapted to the shape and size of the sealing gasket 5. The sealing gasket 5 is disposed between the top condenser plate 2 and the middle condenser plate 1, and the upper and lower sides of the sealing gasket 5 contact the annular protrusions of the top condenser plate 2 and the middle condenser plate 1, respectively.

[0046] It is understandable that, since the top of the top condenser plate 1 also has an annular protrusion, a cavity is constructed between the top condenser plate 2 and the middle condenser plate 1. Compared to the fact that the bottom of the top condenser plate 2 and the top of the middle condenser plate 1 are both flat, the space between the top condenser plate 2 and the middle condenser plate 1 can hold more liquid.

[0047] like Figure 1 As shown, in order to increase the volume for liquid containment between the middle condenser 1 and the middle condenser 1, this embodiment preferably provides annular protrusions on the top of each middle condenser 1. The annular protrusions are circular, and their shape and size are adapted to the shape and size of the sealing gasket 5. When the sealing gasket 5 is placed between the middle condenser 1 and the middle condenser 1, the upper and lower sides of the sealing gasket 5 respectively contact the annular protrusions of the two middle condenser 1.

[0048] It is understandable that because the bottom and top of the middle condenser plate 1 are provided with annular protrusions, a cavity is constructed between the upper and lower middle condenser plates 1. Compared to making the bottom and top of the middle condenser plate 1 flat, the space between the middle condenser plates 1 can hold more liquid.

[0049] like Figure 5 As shown, in order to increase the volume for liquid containment between the bottom condenser plate 3 and the middle condenser plate 1, this embodiment preferably has an annular protrusion on the top of the bottom condenser plate 3. The annular protrusion is circular, and its shape and size are adapted to the shape and size of the sealing gasket 5. When the sealing gasket 5 is placed between the bottom condenser plate 3 and the middle condenser plate 1, the upper and lower sides of the sealing gasket 5 contact the annular protrusion of the bottom condenser plate 3 and the middle condenser plate 1, respectively.

[0050] It is understandable that because the top of the bottom condenser plate 3 has an annular protrusion, a cavity is constructed between the bottom condenser plate 3 and the middle condenser plate 1. Compared to making the top of the bottom condenser plate 3 and the bottom of the middle condenser plate 1 both flat, the space between the bottom condenser plate 3 and the middle condenser plate 1 can hold more liquid.

[0051] like Figure 4As shown, the top-layer condenser plate 2 of this embodiment is provided with an injection channel 21, which is vertically arranged and circular. The injection channel 21 is used to inject liquid from the outside into the condenser. An injection cylinder 22, also cylindrical, is fixedly installed inside the injection channel 21. The injection cylinder 22 can be fixedly installed inside the injection channel 21 by welding or other methods in the prior art. The upper and lower ends of the injection cylinder 22 are connected to the inner wall of the injection channel 21, so that a gap is formed between the inner wall of the injection channel 21 and the outer wall of the injection cylinder 22 at the middle position of the injection channel 21. The inner wall of the injection cylinder 22 is provided with enamel 4.

[0052] It is understood that in this embodiment, an injection cylinder 22 is provided inside the injection channel 21, which increases the strength of the injection channel 21. Furthermore, the gap between the injection cylinder 22 and the injection channel 21 can mitigate the impact on the injection cylinder 22. Therefore, when liquid flows inside the injection cylinder 22, the enamel 4 on the inner wall of the injection cylinder 22 is less likely to be damaged, preventing cracking of the enamel 4 on the inner wall of the injection cylinder 22.

[0053] like Figure 5 As shown, the bottom condenser plate 3 of this embodiment is provided with a discharge channel 31, which is vertically arranged and circular. The discharge channel 31 is used to discharge liquid from the condenser to the outside. A discharge cylinder 32, also cylindrical, is fixedly installed inside the discharge channel 31. The discharge cylinder 32 can be fixedly installed inside the discharge channel 31 by welding or other methods in the prior art. The upper and lower ends of the discharge cylinder 32 are connected to the inner wall of the discharge channel 31, so that a gap is formed between the inner wall of the discharge channel 31 and the outer wall of the discharge cylinder 32 at the middle position of the discharge channel 31. The inner wall of the discharge cylinder 32 is also provided with enamel 4.

[0054] It is understood that in this embodiment, a discharge cylinder 32 is provided inside the discharge channel 31, which can increase the strength of the discharge channel 31. Furthermore, the gap between the discharge cylinder 32 and the discharge channel 31 can mitigate the impact on the discharge cylinder 32. Therefore, when liquid flows inside the discharge cylinder 32, the enamel 4 on the inner wall of the discharge cylinder 32 is less likely to be damaged, preventing cracking of the enamel 4 on the inner wall of the discharge cylinder 32.

[0055] The above only is the embodiment of the present application, and the well-known specific structure and characteristics and other common knowledge in the scheme are not described too much here. It should be pointed out that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope claimed in the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
