The centre distance of adjacent plate: the honeycomb height of 1.5 times of plates.
The intensified heat transfer method of the utility model is following:
1, augmentation of heat transfer in the plate:
The honeycomb that plate in the heat exchanger is the given shape distribution forces flowing velocity and the flow direction of fluid in plate constantly to change; Fluid and the cellular site formation jet that constantly collides; The local little whirlpool that produces constantly destroy or the attenuate plate in detention layer, impel to be flowing under the lower Reynolds number by laminar flow to turbulent transition, make fluid flow and form turbulent flow easily; Thereby increase flow-disturbing effect, played the effect of augmentation of heat transfer the plate inner fluid.
2, augmentation of heat transfer between plate:
Being staggered of length plate makes formation muitishell flow channel space in the housing, and the shell side runner is elongated, and rate of flow of fluid is accelerated, thereby has strengthened the heat transfer of shell-side fluid.Add the special honeycomb of plate, wooden partition forms cellular groove at the cellular site place, and the little whirlpool that shell-side fluid bump groove wall produces is constantly washing away the boundary layer, weakens the formation in boundary layer, has played certain augmentation of heat transfer effect.Simultaneously, form a flowing space between the adjacent two boards sheet relatively, speed increased when shell-side fluid flow to, and speed reduces during outflow, and flow velocity always is in regular state of disturbance, has increased thermal diffusivity, has promoted the mixing of fluid, has strengthened heat transfer.
The utility model compared with prior art has following advantage and beneficial effect:
(1) the utility model adopts the different plate of width to form round-shaped plate bundle (see figure 2); Heat transfer area is increased; Space between cylindrical shell and the tube bank is greatly reduced, thereby effectively prevented the short circuit of shell-side fluid, the heat exchange effect is obviously improved.
(2) the reasonable utilization of length plate has realized that the muitishell of lamella heat exchanger flows, and the shell side flow velocity strengthens, and has reduced dirt deposition, has improved heat transfer efficiency.In addition, do not weld between plate, rely on being separated by and support of pull bar, make things convenient for dismounting, cleaning, replacing and the assembling of plate, pull bar.
(3) formed the runner of complicated compactness in the big and plate of heat exchange area, flow velocity increased and continuous collision cellular site when fluid flowed in plate, promoted the generation of flow-disturbing effect, and heat (cold) exchange is quickened, and had strengthened the augmentation of heat transfer effect.The utility model plate has superior manufacturing process and heat exchange property, as heat exchange element, increases the heat exchange property of lamella heat exchanger with the honeycomb plate greatly.
(4) because the runner cavity adopts honeycomb, plate has the ability of bearing external pressure preferably; Each piece honeycomb plate amalgamation forms the plate bundle, need not weld between the plate, leans on double tube sheet to guarantee the sealing property between shell.Heat exchanger has dismoutability, can be used for the occasion that needs often clean.
