Description

Technical Field

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

[0002] Shell and tube condensers are divided into three types according to the material: carbon steel shell and tube condensers, stainless steel shell and tube condensers, and carbon steel and stainless steel mixed shell and tube condensers. According to the form, they are divided into fixed tube plate type, floating head type, and U-tube heat exchangers. According to the structure, they are divided into single tube pass, double tube pass, and multi-tube pass. The heat transfer area is 0.5-500 square meters. It can be customized according to user needs. The condenser in the evaporation equipment uses cooling water to cool the secondary steam. It can be divided into two categories, one is an indirect condenser and the other is a direct condenser. Indirect condensers are also called surface condensers, including shell and tube condensers, coil condensers, and plate condensers. More and more evaporation equipment at home and abroad uses shell and tube condensers. The heat transfer area of ​​the condenser must be sufficient, otherwise the secondary steam entering the condenser will be difficult to be completely cooled, causing the evaporation temperature to rise, thereby reducing production capacity. In addition to selecting a suitable heat transfer coefficient for the condenser, some factors that directly affect the heat transfer effect when calculating the heat transfer area of ​​the condenser cannot be ignored.

[0003] The application number is CN201520818961.3, which discloses a heat exchange device for a gas heating condensing wall-mounted boiler, including an independent main heat exchanger and a condensing heat exchanger, the main heat exchanger and the condensing heat exchanger have the same cross-sectional size, are arranged up and down, and are detachably connected, the upper end of the main heat exchanger is directly connected to the burner, and the flue gas is discharged after heat exchange through the main heat exchanger and the condensing heat exchanger in sequence; the main heat exchanger includes a main heat exchange shell and a main heat exchange module, and the condensing heat exchanger includes a condensing heat exchange shell and a condensing heat exchange module, both shells are rectangular frames welded by stainless steel plates, and the shells are stamped with convex water bags for transition structures for water flow diversion in the corresponding heat exchange modules, and the structures of the two heat exchange modules include a plurality of parallel stainless steel heat exchange tubes and a plurality of parallel stainless steel fins for fixing the heat exchange tubes, and the two heat exchange modules are respectively placed at the bottom of the corresponding shell inner cavity. The stainless steel material has an anti-corrosion function, and the tube-fin structure of the two heat exchange modules has a large heat exchange area and high heat exchange efficiency.

[0004] Although the above utility model has a main heat exchange shell and a main heat exchange module, the condensing heat exchanger includes a condensing heat exchange shell and a condensing heat exchange module, and both shells are rectangular frames welded with stainless steel plates, and the shells are stamped with convex water bags for transition structures for water flow diversion in the corresponding heat exchange modules. The structures of the two heat exchange modules include a plurality of parallel stainless steel heat exchange tubes and a plurality of parallel stainless steel fins for fixing the heat exchange tubes, and the two heat exchange modules are respectively placed at the bottom of the corresponding shell cavity. Stainless steel material has anti-corrosion function, and the tube-fin structure of the two heat exchange modules has a large heat exchange area and high heat exchange efficiency, but there is a disadvantage that the device needs to be rotated and fixed by bolts during installation, which makes it time-consuming and laborious to disassemble and maintain in the subsequent process.

[0005] Therefore, it is necessary to install an installation component on the back of the heat exchanger, which can make it more convenient to disassemble, maintain and repair the heat exchanger in the future, and provide a certain convenience in disassembly and installation. Utility Model Content
