Abstract
The utility model relates to a heat exchanger with a protruded pipe, which only makes deformation and improvement on a heat exchanger on the structural basis of a present heat exchanger with pipe array. The pipe wall of the heat exchanger is provided with drum bags which are crosswise arranged in a longitudinal direction, and accordingly, a protruded pipe is formed. Liquid can generate turbulent flow to destroy a boundary layer between the fluid and the pipe wall of the heat exchange, and simultaneously, the heat exchange area with the same unit length is increased. The utility model has the characteristics of high heat exchange efficiency, small size, etc.
Description
The utility model relates to heat exchanger.
Heat exchanger tube in the tubular heat exchanger generally adopts light pipe at present, because the heat exchanger tube smooth surface, the thermal resistance that formation a kind of " boundary layer " produces because of the boundary layer between fluid and the heat exchanger tube surface in heat transfer process can make heat exchanger heat exchange effect reduce several times.For above-mentioned reasons, efficiency of heat exchanger is lower, causes the liquid expense of the energy.
The purpose of this utility model promptly is to adopt at above-mentioned tubular heat exchanger the heat exchanger tube of smooth surface, in heat transfer process, easily form the boundary layer between fluid and the heat exchanger tube surface, because of the existence generation thermal resistance in boundary layer, the problem that heat exchange efficiency is reduced greatly, and a kind of knurl heat exchange of heat pipe is provided.
The purpose of this utility model is to realize like this, be exactly on the architecture basics of present tubular heat exchanger, only exchanging heat pipe does to improve, be pressed into the bulge of vertical cross arrangement at the tube wall of heat exchanger tube, thereby fluid constantly changes direction and speed, impels turbulent flow to strengthen the boundary layer thickness attenuate, the heat exchanger tube wall pressure becomes bulge to increase heat exchange area, thereby has reached above-mentioned the purpose of this utility model.
Major advantage of the present utility model:
1, heat exchange efficiency height: because the bulge on the heat exchange tube wall improves heat transfer coefficient (K value), so the heat exchange effect can improve more than 2 times.
2, volume is little: because the heat exchange tube wall increases bulge, and at the same unit length increase heat exchange area of heat exchanger tube, the raising of heat exchanger tube heat transfer coefficient simultaneously, if obtain identical heat, this heat exchange body can reduce more than 50%.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of a vapour-liquid heat exchanger of providing of the utility model.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
See also Fig. 1, the utility model comprises shell 1, heat exchanger tube 2, adapter mouth 3, adapter mouth 4, takes over mouth 5, adapter mouth 6, knows clearly as following table:
| Take over numbering | Vapour-water heat exchange | Water-water heat exchange |
| Take over 3 | The heating steam inlet | Be heated water out |
| Take over 4 | Condensation-water drain | Be heated water inlet |
| Take over 5 | Be heated water out | Add the hot water inlet |
| Take over 6 | Be heated water inlet | Add hot water outlet |
It below all is existing structure.
Principal character of the present utility model is provided with a plurality of bulges 7 in the wall portion of heat exchanger tube 2 as shown in Figure 2, can take continuously arranged in a crossed mannerly, and the height of bulge 7 depends on the size of heat exchanger tube 2 diameter D, its spacing S=0.9D, height H=0.15D.
Claims (4)
1, a kind of energy-efficient knurl heat exchange of heat pipe comprises shell, heat exchanger tube, adapter mouth, it is characterized in that the wall of heat exchanger tube 2 is provided with bulge 7.
2, knurl heat exchange of heat pipe according to claim 1 is characterized in that bulge 7 for sinusoidal arc, and its spacing is S, highly is H.
3, knurl heat exchange of heat pipe according to claim 1 is characterized in that bulge 7 is intersection setting.
4, knurl heat exchange of heat pipe according to claim 1 is characterized in that the interval S=0.9D of bulge 7, height H=0.15D.
