Problems solved by technology
However, the existing heat exchangers are almost all single-layer liquid distribution, and the influence of the height of the heat exchange tube on the heat exchange is not considered. When the heat exchanger exceeds a certain height, due to the viscous force and shear force on the wall of the heat exchange tube effect, the heat transfer efficiency will be greatly reduced

The invention relates to the technical field of heat exchange devices, in particular to a vertical heat pipe bundle type heat exchanger which comprises a heat exchanger shell, partition plates, a vertical pipe bundle, a hot water inlet, a hot water outlet, an upper end cover, a lower end cover, an upper pipe plate and a lower pipe plate. The heat exchanger shell is welded between the upper pipe plate and the lower pipe plate. The hot water inlet is formed in the upper portion of one side of the heat exchanger shell, and the hot water outlet is formed in the lower portion of the same side of the heat exchanger shell. The partition plates are installed in the heat exchanger shell. Each layer of liquid distribution device is composed of a liquid discharging pipeline, a baffle plate and a supporting frame. The partition plate on the top layer can only be provided with the baffle plate. The installation layer number of the partition plates is set to be three or more according to the heightof the vertical heat exchanger and the flow state of a liquid film outside a pipe, and all the layers of the devices are fixedly connected through supports and further welded to the lower pipe plate.The vertical pipe bundle is longitudinally arranged in the heat exchanger shell, penetrates through each layer of the liquid discharging pipeline and the baffle plate and is fixed to pipe holes of theupper pipe plate and the lower pipe plate.
Description
technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a vertical heat pipe bundle heat exchanger. Background technique [0002] Introduction: Tubular (also known as shell-and-tube, shell-and-tube) heat exchanger is the most typical partitioned wall heat exchanger. It has a long history of industrial application and is still dominant in all heat exchangers. status. The tubular heat exchanger is mainly composed of a shell, a tube bundle, a tube sheet, and a head. The shell is mostly circular, and parallel tube bundles are installed inside. Due to the influence of the tube bundle effect, the sewage is prone to drift, droplet splashing or uneven film thickness outside the tube, and it is difficult to form a uniform and complete liquid film on the surface, which has become the main problem restricting the heat transfer efficiency of the heat exchanger. The current tube bundle heat exchanger is cold water inside or outside...
