Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] figure 1 Among them, it consists of cold fluid inlet 1, cold fluid outlet 2, hot fluid inlet 3, hot fluid outlet 4, heat exchange unit 5, upper head 6, cold fluid connecting air duct 7 and lower head 8; heat exchange unit 5 The schematic diagram of the structure is attached figure 2 , attached image 3 As shown, it is composed of a shell 51, a plate tube 52, an edge spoiler 53, an upper tube plate 54 and a lower tube plate 55. The plate tube 52 is composed of two stacked and connected special-shaped plates with wave grooves. , in the heat exchanger shell 51, there are special-shaped plates with repeated and continuous transverse ribs and longitudinal wave grooves, and the crests of the wave grooves of two adjacent special-shaped plates are overlapped and connected to form a plate tube 52. For every two special-shaped plates in one special-shaped plate, the c...

Abstract

The invention provides a wave-shaped plate with cross rib tubular type heat exchanger, comprising shell, wave-shaped plate with cross rib, upper and lower tube plates which are connected together, fluid state inside and outside the wave-shaped plate with cross rib both flows along rough rib surface optimized which can promote turbulent flow of fluid on boundary layer and intensification of heat transfer effect to the fluid. The invention with wide plate spacing, is suitable for heat exchange between hot-cold gas fluid with low ordinary pressure and large volume, and has the advantages that overall coefficient of heat transfer is high, heat exchange effect is excellent, materials needed are few, investment to apparatus is low, convenient to produce and apply.

Description

technical field [0001] The invention belongs to the field of heat exchangers, in particular to a corrugated plate-tube heat exchanger with transverse ribs. technical background [0002] There are many structures of plate heat exchangers, most of which are herringbone corrugated plate heat exchangers with narrow plate spacing for liquid phase fluid heat exchange or gas condensation. The plate spacing is less than 15mm, and the hot and cold fluids are countercurrent heat exchange. [0003] Chinese Patent No. 02209191.2 discloses a plate heat exchanger, including heat transfer plates, small connecting pipes, large connecting pipes, fixed compression plates, movable compression plates, and studs, and is characterized in that the sealing of the heat transfer plates The pad groove is a half-depth groove with gaps evenly distributed across two corresponding groove sides. The front and back sides of the heat transfer plates are stacked, so that the gasket gr...
