Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically to a corrosion-resistant heat exchanger. Background Technology
[0002] Jacketed heat exchangers are a type of indirect heat exchanger. They are made by installing a jacket on the outer wall of the container. They have a simple structure and an anti-corrosion layer inside the cavity, which can play a role in preventing corrosion. In the existing technology, when liquid is introduced into the anti-corrosion heat exchanger, the liquid inside is difficult to fully exchange heat with the heat exchange medium in the jacket, resulting in less than ideal heat exchange efficiency.
[0003] For example, patent publication number CN216049319U describes a corrosion-resistant heat exchanger, including a heat exchanger body with a shell installed on its exterior. Support frames are inserted into both ends of the heat exchanger body, and a liquid collection plate is installed below the support frames. A liquid collection chamber is formed inside the liquid collection plate, and a drain trough is formed within the liquid collection chamber. A guide pipe is connected to the upper end of the drain trough, and the lower end of the support frame is fixedly connected to the upper surface of the liquid collection plate. This corrosion-resistant heat exchanger has four drain troughs and four guide pipes, each corresponding to a drain pipe. The drain troughs allow the discharged liquid to be discharged from the drain pipe. To prevent liquid accumulation and avoid corrosion at the bottom of the heat exchanger body, the exterior of the heat exchange chamber is covered with a corrosion-resistant layer. This layer improves the corrosion resistance of the heat exchanger. The corrosion-resistant layer is a component made of a carbon nanoparticle polymer material. This material enhances the corrosion resistance of the heat exchanger, ensuring its long-term use, extending its service life, and improving its heat exchange efficiency. However, when this type of corrosion-resistant heat exchanger is introduced with liquid, the liquid inside is difficult to fully exchange heat with the heat exchange medium in the jacket, resulting in less than ideal heat exchange efficiency.
