Abstract

The utility model relates to a bothway enhancement heat transfer pipe heat exchanger which comprises a heat exchanger containing cavity with a fluid inlet-outlet opening, a plurality of heat exchange pipes and end covers with channel openings, wherein the heat exchange pipes are arranged in the heat exchanger containing cavity, end plates are arranged at the two ends of the heat exchange pipes, and the end covers are arranged on the outer sides of the end plates. The bothway enhancement heat transfer pipe heat exchanger is characterized in that three-dimensional taper fins or spiral grooves which are machined through extrusion, rolling and plough cutting technologies are formed in the outer surfaces of the heat exchange pipes, and concave-convex lines are formed in the heat exchange pipes. Compared with the prior art, the bothway enhancement heat transfer pipe heat exchanger has the advantage that the heat exchange efficiency can be improved.

Description

Biaxial strengthening heat-transfer pipe heat exchanger
Technical field:
The utility model relates to a kind of heat exchanger.
background technology:
Traditional heat exchanger, what heat-transfer pipe was used is light-pipe structure, or screwed pipe, bellows, bellows tube etc., because the surface of these pipes is all level and smooth, therefore, increase heat exchange area, can only increase the quantity of pipe, self volume of heated exchanger limits, and the quantity of pipe is conditional, thereby has suppressed the heat exchanger effectiveness of heat exchanger.Adopt the three-dimensional conical finned heat-transfer pipe of biaxial strengthening to impel the kinetic energy of fluid to act on sufficiently uniformly on enhanced heat exchange face, make the conveying function of fluid most effectively for promoting the heat convection strengthening on heat transfer interface, overcome traditional heat exchangers and in part, form resistance greatly and the shortcoming of the convection heat transfer' heat-transfer by convection poor performance of heat transfer interface.
summary of the invention:
Goal of the invention of the present utility model is to provide a kind of biaxial strengthening heat-transfer pipe heat exchanger that can improve heat exchanger effectiveness.
The utility model is to realize like this, comprise with the heat exchanger cavity volume of fluid inlet and outlet, be arranged on two ends in heat exchanger cavity volume with several heat exchanger tubes of end plate, be arranged on the end cap with passway in end plate outside, its special feature is that heat exchanger tube is that outer surface has the three-dimensional conical finned or the helical groove that by extruding pressure, rolling, plough cutting process, are processed, forms concavo-convex line in pipe.
Adopt the three-dimensional conical finned heat-transfer pipe of biaxial strengthening, made heat exchanger tube pass inner fluid produce flow-disturbing and vortex phenomenon, thereby taken away with many heats, improved heat-transfer effect; And medium in shell side, because three-dimensional conical finned adopts the manufacture of extruding/rolling-plough incision technology, be three-dimensional cone-shaped, fin height is high, increased heat transfer area, and fin root is connected firmly, even if fin is subject to medium certain pressure, current downflow is washed away and difficult drop-off repeatedly, has the advantages that heat transfer efficiency is high, clean, the life-span is long; Realized the heat-transfer effect of biaxial strengthening.
Adopt the three-dimensional conical finned heat-transfer pipe of biaxial strengthening to impel the kinetic energy of fluid to act on sufficiently uniformly on enhanced heat exchange face, make the conveying function of fluid most effectively for promoting the heat convection strengthening on heat transfer interface, overcome traditional heat exchangers and in part, form resistance greatly and the shortcoming of the convection heat transfer' heat-transfer by convection poor performance of heat transfer interface.Based on extruding/rolling---the manufacture of plough incision technology, there is Multi-scale model feature, and it is concavo-convex to make to manage interior formation, strengthen medial and lateral (biaxial strengthening) heat-transfer capability simultaneously, impel the raising of heat transfer property, therefore there are wide market prospects.
Compared with the prior art the utility model, has advantages of and can improve heat exchanger effectiveness.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of heat exchanger tube embodiment 1;
Fig. 3 is the structural representation of heat exchanger tube embodiment 2
implementation method:
With reference to Fig. 1, the utility model biaxial strengthening heat-transfer pipe heat exchanger, with the heat exchanger cavity volume (socket assembly) 4 of fluid inlet and outlet 6, be arranged on two ends in the heat exchanger cavity volume 4 several heat exchanger tubes (biaxial strengthening heat-transfer pipe) 3 with end plate (end tube sheet) 1, be arranged on the several deflection plates 2 on several heat exchanger tubes 3, be arranged on the end cap with passway 7 (water cover) 5 in end plate 1 outside, its special feature is that heat exchanger tube 3 is that outer surface has by pushing, rolling, several helical grooves 8(embodiment 1 that plough cutting process processes: as shown in Figure 2, by pushing, rolling mill practice manufacture forms) or three-dimensional conical finned 9(embodiment 2: the last plough cutting process manufacture on embodiment 1 basis forms), in pipe, form concavo-convex line 10.
