Embodiment Construction
[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0032] A heat exchanger of the present invention, the heat exchanger can be a fixed tube-sheet heat exchanger, a floating head heat exchanger, or a combination of different heat exchangers such as parallel, series or hybrid. Such as figure 1 As shown, the heat exchanger of the present invention includes a shell-side cylinder 5, a tube plate 1 installed inside the shell-side cylinder 5, a tube bundle and a baffle grid plate 3, and the tube bundle passes through the baffle grid plate 3 and is connected with it. The tube sheet 1 at the end is fixedly connected, and the outer sides of the tube sheets 1 at the left and right ends of the tube bundle are respectively provided wi...

The invention relates to the technical field of heat exchange, and discloses a heat exchanger and a method for enhancing heat exchange, including a shell-side cylinder, a tube sheet installed inside the shell-side cylinder, a tube bundle and a baffle grid plate, and the tube bundle passes through the folded The flow grid plate is fixedly connected with the tube plates at both ends. The cross-section of the tubes in the tube bundle is a polygonal structure, and the edges of the polygonal tubes are rounded; holes and fixing holes; the baffle gratings are a plurality of pieces arranged in parallel along the direction of the tube, and the bow-shaped grilles of adjacent baffle gratings are distributed in a staggered manner. The fluid in the shell side of the present invention forms a "Karman vortex" when it flows through the grid of the baffle plate, and the fluid has a small spin flow resistance, which increases the flow velocity of the boundary layer and effectively strengthens the convective heat transfer of the fluid. There is no hygienic dead angle on the wall surface and it is easy to clean. The gap between the tubes of the tube bundle is a similar rectangular gap, accompanied by the "Venturi" effect, and its heat transfer effect can be further greatly improved.
Description
technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchanger and a method for enhancing heat exchange. Background technique [0002] Petrochemical, pharmaceutical and other industries are vigorously developing large-capacity, high-performance heat transfer equipment, and have special requirements for the size and weight of heat transfer equipment. Especially in the pharmaceutical industry, there is a need for miniaturized heat exchanger equipment that is easy to clean and clean, conforms to industry standards, has a small volume, and has a large heat transfer area per unit volume, so as to meet the product quality management, clean production and environmental protection requirements of the pharmaceutical industry. At present, heat exchangers suitable for petrochemical, pharmaceutical and other industries generally include shell-and-tube heat exchangers and plate heat exchangers. [0003] Shell-and-tube heat exchang...
