Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a detachable heat exchanger. Background Art

[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid, also known as heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, evaporators and reboilers. Existing heat exchangers are used as a whole to exchange heat, and some parts are damaged, so they need to be replaced as a whole, and subsequent disassembly and assembly are also difficult. In addition, existing heat exchangers cannot be adjusted in real time according to the heat exchange area, so their practicality is worse than that of cars. Utility Model Content

[0005] In some embodiments, two groups of liquid-conducting cavities are provided in the main housing and are symmetrical with each other. Sealing rubber rings are provided in the liquid-conducting cavities to perform a sealing function.

[0006] In some embodiments, the heat exchange tubes are inserted into the two groups of the liquid guide cavities that are symmetrical on both sides and abut against the sealing rubber rings, and a heat exchange cavity is provided in the heat exchange tubes.

[0007] In some embodiments, a metal frame is fixedly provided on the right end surface of the main box body.

[0008] In some embodiments, a guide cavity connected to the outside is provided on the left side of the main box body, an electromagnet is fixedly provided on the inner wall of the guide cavity, and the metal frame cooperates with another group of the electromagnets magnetically, thereby facilitating assembly and installation.

[0009] Compared with the prior art, the advantages of the utility model are:

[0010] 1. The utility model starts reverse starting through a threaded motor, which in turn drives the threaded screw to reverse, thereby driving the threaded slider and the clamping frame to move away from each other. At this time, the heat exchanger is divided into a heat exchange tube and a main box body, which is convenient for subsequent block maintenance, thereby ensuring that it can be accurately replaced according to the damaged part, further reducing losses, and further facilitating subsequent disassembly and assembly. A group of metal frames is inserted into another group of guide cavities. At this time, another group of electromagnets and the inserted metal frames are magnetically matched, thereby realizing the area and amount of heat exchange, and then real-time adjustment for disassembly and assembly, thereby ensuring that the heat exchange power is maximized, thereby improving the practicality of the heat exchanger.
