Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and more specifically, to an ammonia water heat exchanger. Background Art

[0002] In the existing technology, the ammonia water heat exchanger is a heat exchange equipment that uses ammonia water as a heat exchange medium. It can play an important role in many industries such as chemical, petroleum, electricity, and food. In the existing ammonia water heat exchanger technology, most heat exchangers adopt an integrated design, which means that the various parts of the heat exchanger are fixed together and there is no disassembly function for external parts. Although this design simplifies the manufacturing process to a certain extent, it brings inconvenience when maintaining and replacing internal parts. Since the internal parts cannot be easily accessed, the maintenance and replacement work becomes complicated and time-consuming, which may affect the normal operation of the entire system;

[0003] To solve this problem, some ammonia water heat exchangers adopt a split design, which allows the main components of the heat exchanger to be separated for easy maintenance and replacement. However, the existing split design often relies on flanges and bolts for connection. Although this connection method improves maintainability to a certain extent, the bolt fixing method is usually laborious and cannot achieve quick installation and disassembly. This connection method requires the use of tools to tighten and loosen the bolts, which not only increases maintenance time, but may also cause bolt damage or thread wear due to improper operation;

[0004] There are deficiencies in the reinforcement support mechanism for heat exchange tubes in the prior art. Heat exchange tubes are key components for transferring heat in heat exchangers, and their stability and durability directly affect the performance and life of the heat exchanger. However, existing heat exchanger designs often lack sufficient reinforcement of heat exchange tubes, which may cause the heat exchange tubes to deform or be damaged in high temperature, high pressure or vibration environments, thereby affecting the heat exchange efficiency and service life.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides an ammonia water heat exchanger, which has the following beneficial effects:

[0018] 1. The installation mechanism realizes the modular design of the heat exchanger through the combination of the shell, cover, ammonia water inlet pipe, ammonia water outlet pipe, flange and connecting pipe, which is convenient for quick installation and disassembly. The setting of the shell protects the internal structure. The installation of the cover is convenient for sealing the heat exchanger to prevent medium leakage. The design of the ammonia water inlet pipe and outlet pipe makes the medium flow smoother. The use of flange and connecting pipe simplifies the connection process between the heat exchanger and the external pipeline. The design of this installation mechanism, especially the use of the clamping mechanism, greatly improves the maintenance convenience of the heat exchanger, so that the internal parts of the heat exchanger can be quickly and easily replaced and repaired.

The clamping mechanism includes a clamping rod, a clamping hole, a clamping sleeve, a clamping block, a screw, a sliding sleeve, a gear, a control sleeve, a rack, an unlocking sleeve and an unlocking block. This design realizes the rapid installation and disassembly of the cover and the connecting pipe. Through the threaded connection of the screw and the sliding sleeve, and the meshing of the gear and the rack, the sliding of the clamping block along the clamping sleeve is realized, so as to quickly complete the clamping and release. The application of the push spring ensures the stable clamping of the clamping block in the clamping hole, and the cooperation of the unlocking block and the limit groove realizes the rapid release of the clamping mechanism. The design of this clamping mechanism not only reduces the maintenance time, but also reduces the operating intensity, and improves the interchangeability of heat exchanger components and the overall reliability of the system.
