Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and in particular to an adjustable branch flow channel exchange structure and a heat exchanger capable of adjusting the fluid heat exchange temperature. Background Art

[0002] Heat exchanger, also known as heat exchanger, is a device used to transfer part of the heat of hot fluid to cold fluid. It plays an important role in many industrial productions such as chemical, petroleum, power, food, etc. It can be used as heater, cooler, condenser, evaporator and reboiler, etc.

[0003] The working principle of the heat exchanger is based on heat conduction. It usually consists of two fluid channels: the fluid channel on the heat source side and the fluid channel on the heat load side. During the working process, the heat source (such as steam, hot water, etc.) in the fluid channel on the heat source side enters the heat exchanger through the pipe, passes through the pipes and heat exchange surfaces inside the heat exchanger, and transfers the heat to the heat load (such as water, air, etc.) in the fluid channel on the heat load side, raising its temperature. At the same time, the heat load in the fluid channel on the heat load side transfers the heat to the heat source in the fluid channel on the heat source side through the heat exchange surfaces and pipes, lowering its temperature.

[0004] Exchanging heat for fluids in an underwater hull usually involves special engineering design and considerations, as the underwater environment places very different requirements on equipment than onshore environments. Due to the limited space in the hull, a compact heat exchanger needs to be designed based on the space constraints within the hull. Existing heat exchangers often use manifolds to increase the contact area between the fluid and the heat exchanger, but this does not reduce or increase the efficiency of the heat exchanger depending on the usage.

[0005] Currently, no effective solution has been proposed for the problems existing in the related art, such as the fixed flow channel of the existing heat exchanger and the inability to adjust the heat exchange efficiency. Utility Model Content
