Description

Technical Field

[0001] The utility model relates to the technical field of condensers, in particular to a novel enamel condenser sheet and a condenser. Background Art

[0002] The enamel plate condenser currently in use is a circular curved single-hole or multi-hole condenser. The front and back sides of the plate are concave and convex. Therefore, in the case of thermal deformation, high cooling water pressure, and large vacuum negative pressure, it is easy to cause porcelain explosion on the convex surface and the material hole. The material flow layer space is large, which affects the cooling effect. The cooling water has no diversion on the two opposite sides of the circular convex plate for inlet and outlet water. The inlet and outlet water stays in the jacket for a short time and basically passes directly, so that the water on both sides of the circular plate cannot flow fully, so it can only take out a small amount of heat, and the solid heat exchange effect is poor.

[0003] The enamel surface of the prior art enameled sheet condenser is horizontal. The material needs to flow to the next flat plate condenser. The main method is to open two grooves on the enamel surface, and the material flows to the next enamel sheet through the two grooves. Since the two grooves opened on the enamel plane are connected to the holes opened on the enamel plane, the two grooves destroy the integrity of the enamel holes, making it impossible to release the stress in the enamel holes. These stresses are not completely eliminated on the enamel, which will cause the enamel to crack. When the enameled sheet condenser is operating under temperature and pressure, the enamel hole position is very prone to cracking. Utility Model Content

[0004] The first aspect of the utility model aims to solve the problem in the prior art that two grooves are opened on the enamel plane to connect with the enamel hole, which destroys the integrity of the enamel hole and causes porcelain explosion at the enamel hole position. A new enamel condenser is provided, which changes the prior art method of drainage by opening grooves into a method of drainage by setting the whole as an inclined surface, and sets the material hole at the inclined lower end of the inclined surface, which ensures the integrity of the material hole while draining, and avoids porcelain explosion of the condenser. The main concept is:

In this solution, a groove is processed in the middle position of the upper part, and the bottom of the groove is set as an inclined surface, so that the material is drained to the material feeding hole under the action of the inclined surface, and the opening direction of the material feeding hole is in the vertical direction. The material feeding hole is opened on the inclined surface so that the material feeding hole is also inclined. In this solution, the material feeding hole is completely opened on the inclined surface, and there will be no concentrated stress in the material feeding hole, and the porcelain explosion phenomenon will not occur under the condition of temperature and pressure.

[0011] The second aspect of the utility model solves the technical problem that the interior of the condensing sheet is a hollow structure, resulting in low overall strength and easy deformation. Furthermore, reinforcing ribs are arranged in the internal cavity, and the reinforcing ribs are connected to the upper part and the lower part. Reinforcing ribs are arranged in the internal cavity, and the reinforcing ribs act on the upper part and the lower part to enhance the yield strength of the condensing sheet, so that the condensing sheet can adapt to the high water pressure environment.

[0012] The third aspect of the utility model solves the technical problem that the residence time of the refrigerant in the internal cavity is too short, resulting in poor heat exchange effect of the condensing plate.
