Therefore, the total amount of liquid that can be accommodated between two condensing sheets is small. When the total amount of liquid that can be accommodated between the condensing sheets is small, the heat exchange effect with the liquid in the condenser is poor. UTILITY MODEL CONTENTS

[0017] Preferably, in order to increase the strength of the annular convex, the outer circle of the annular convex extends to the edge of the condensing sheet.

[0018] Preferably, since the sealing gasket needs to be in contact with liquid, in order to prevent the liquid from corroding and damaging the sealing gasket, the sealing gasket comprises an inner skeleton and an anti-corrosion layer, the inner skeleton is ring-shaped, and the anti-corrosion layer is provided on the surface of the inner skeleton.

[0019] The anti-corrosion layer prevents corrosion of the inner skeleton, preventing the sealing gasket from being corroded and damaged.

[0020] Preferably, the inner skeleton serves as a support, and in order to avoid hard contact with the outside, the inner skeleton comprises a support ring and a buffer ring, the buffer ring is provided in two, and the support ring is provided between the two buffer rings.

[0024] The present application has the beneficial effect that the annular protrusion is arranged on the surface of the condensing sheet. At the same time, the sealing gasket is also arranged on the surface of the annular protrusion. Therefore, compared with the prior art in which the surface of the condensing sheet is arranged as a plane, the inner circle of the annular protrusion can also accommodate liquid, and when the condensing sheet surface accommodates more liquid, the heat exchange effect of the liquid on the condensing sheet surface and the liquid inside the condensing sheet is better.

[0040] The fixed structure of the embodiment includes several connecting units, and the connecting units are arranged annularly around the condensing sheet. Each connecting unit includes connecting hook and locking rod, and the connecting hook is arranged as two, and the two connecting hooks hook the bottom of bottom condensing sheet 3 and the top of top condensing sheet 1 respectively. The locking rod is connected with the two connecting hooks, so as to realize the tensioning and fixing of the condensing sheets arranged in up-down.

[0041] In order to realize heat exchange, the top layer condensing sheet 1 is provided with an injection channel 11 vertically penetrating the top layer condensing sheet 1, which can allow liquid to enter the accommodating cavity between the top layer condensing sheet 1 and the middle layer condensing sheet 2 from outside. Meanwhile, the top layer condensing sheet 1 is provided with pipe interfaces at both ends, which are in communication with the inside of the top layer condensing sheet 1, so that the liquid outside can enter the inside of the top layer condensing sheet 1 through the pipe interfaces, and the liquid inside the top layer condensing sheet 1 can also be outputted outside through the pipe interfaces.

[0042] As shown in Figure 3 In order to realize heat exchange, the middle layer condensing sheet 2 is provided with a flow guide channel 21 vertically penetrating the middle layer condensing sheet 2, which can allow liquid to flow from the top of the middle layer condensing sheet 2 to the bottom of the middle layer condensing sheet 2.

The first raw tape layer is arranged on the outer surface of the buffer ring in a winding manner. At the same time, the first raw tape layer can fix the support ring and the fixing layer, so as to keep the support ring and the fixing layer stable.

[0057] It should be noted that the support ring in the embodiment is preferably made of metal material, but in some other embodiments, the support ring can also be made of other materials in the prior art, such as hard plastic.

[0058] After the anti-corrosion layer is arranged on the inner framework, in order to make the anti-corrosion layer more stable and avoid the anti-corrosion ring and the inner framework from being separated, a second raw tape layer is arranged outside the anti-corrosion layer in the embodiment. The second raw tape layer is arranged on the outer surface of the anti-corrosion layer in a winding manner. The second raw tape layer wraps the anti-corrosion layer inside, so as to fix the anti-corrosion layer.
