Abstract

The utility model discloses a novel high-efficiency heat exchanger, which is mainly composed of a pipe box (1), a pipe board (2), a heat exchange pipe of a spiral ionic jet (3), a folding rod part (4), a flow guide cylinder (5), a shell part (6) and a back end structure (7). Because the heat exchange pipe of a spiral ionic jet is used by the novel high-efficiency heat exchanger and an ordinary light pipe heat exchange pipe or a screw thread heat exchange pipe is replaced, thus the heat transfers of a pipe pass and a shell pass are intensified, and particularly the heat transfer intensification of the vapor condensation. At the same time, the scale formation is prevented and delayed. In addition, the actions of an outer flow guide rod and a flow baffling rod enable the fluid flow of the shell pass to be more stable, and the heat transfer of the shell pass is further intensified. The fluid of the shell pass is changed from a radial flow into an axial flow, and thus the vibration of the high efficiency heat exchanger can be eliminated and prevented, and the shell pass resistance force is reduced.

Description

Helix tube ion beam deflection rod heat exchanger

The utility model relates to a kind of heat transmission equipment.

At present, the shell-and-tube heat exchanger of domestic production manufacturer production is to be the deflection plate or the deflection bar type heat exchanger of heat exchanger tube with light pipe or screwed pipe mostly.Do the deflection plate or the deflection rod heat exchanger of heat exchanger tube with light pipe, it is low to compare heat exchange efficiency with helix tube ion beam deflection rod heat exchanger, and when exchanging identical heat for, needed heat exchange area is big; Do the deflection plate or the deflection rod heat exchanger of heat exchanger tube with screwed pipe, the outer heat transfer of its exchange heat pipe pipe is strengthened, and is not strengthened in the pipe.

The purpose of this utility model is that a kind of heat transfer efficiency height will be provided, and eliminates the heat exchanger vibration, the formation that prevents or slow down dirt, a kind of new type heat exchanger of reduction shell side resistance.

The utility model is to realize like this, at first become heat exchanger tube the spiral grooves shape promptly to manage export-oriented indent through mechanical press, the interior spiral of pipe to outer lug, pitch and groove depth can according to circumstances be regulated, and again helix tube are carried out Ion Beam Treatment on ion processing equipment, then by the rod baffle parts, tube sheets etc. are formed the tube bank parts, again with the bobbin carriage parts, housing parts, the rear end structure member is formed heat exchanger.

This heat exchanger is to use through the helix tube of Ion Beam Treatment to make heat exchanger tube, adds rod baffle and outer flow-guiding structure, makes in the Tube Sheet of Heat Exchanger and manage outer heat transfer to be strengthened simultaneously; When being used for the steam condensation, owing to making the steam condensation, the heat exchanger tube through Ion Beam Treatment changes into dropwise condensation by film condensation, thereby improved the heat transfer efficiency of condensation side greatly, because the effect of outer water conservancy diversion and rod baffle structure, eliminated the vibration of heat exchanger again, it is more stable that shell-side fluid is flowed, and further strengthened the shell side heat transfer again, reduced the shell side resistance simultaneously.Helix tube ion beam deflection rod heat exchanger also can prevent and slow down the formation of dirt, prolongs the time between overhauls(TBO), reduces equipment investment and operating cost.

Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing:

Fig. 1, be the structural representation of helix tube ion beam deflection rod heat exchanger;

Fig. 2, be the structural representation of rod baffle parts;

Fig. 3, be the structural representation of spiral ion beam heat exchanger tube.

From Fig. 1-3 as can be known: this heat exchanger is made up of bobbin carriage 1, tube sheet 2, spiral ion beam heat exchanger tube 3, rod baffle parts 4, guide shell 5, housing parts 6, back end structure 7 critical pieces.At first with heat exchanger tube 3, be rolled into spiral grooves, carry out Ion Beam Treatment then, afterwards rod baffle parts 4, tube sheet 2 and spiral ion beam heat exchanger tube 3 etc. are formed the tube bank parts, reinstall housing parts 6, with bolt bobbin carriage 1, with housing parts 6 and afterwards end structure 7 connect to form heat exchanger.

Claims

1, a kind of helix tube ion beam deflection bar type heat exchanger, this heat exchanger is made up of bobbin carriage (1), tube sheet (2), spiral ion beam heat exchanger tube (3), rod baffle parts (4), guide shell (5), housing parts (6), back end structure critical pieces such as (7), it is characterized in that:

A, the outer surface inside sunk spiral groove of spiral ion beam heat exchanger tube (3) for being rolled into, inner surface is the zigzag shape of projection, and by Ion Beam Treatment, groove depth and pitch are decided according to concrete needs.
