Abstract
The utility model relates to a plastic alloy heat exchange pipe and a heat exchanger applying the same. The plastic alloy heat exchange pipe comprises a pipe body which is a flexible hose, and each of the inner surface and the outer surface of the pipe wall of the pipe body is concave-convex. The plastic alloy heat exchange pipe and the heat exchanger have the advantages that each of the inner surface and the outer surface of the pipe body is arranged to be concave-convex, so that heat exchange area of the heat exchanger in unit size is increased; the plastic alloy heat exchange pipe is integrally made by a plastic alloy material, thereby being needless of welding point, and the heat exchange pipe is thin in wall thickness, soft and small in inner diameter of the pipe body, thereby being capable of being spirally arranged, so that heat exchange effect is improved.
Description
Technical field
The utility model belongs to heat-exchanger rig field, relates in particular to a kind of plastic alloy heat exchanger tube and applies the heat exchanger of this heat exchanger tube.
Background technology
It is a kind of at the widely used anticorrosion black vacuum equipment of chemical field that horizontal overall plastic water sprays vacuum unit, form vacuum by current high velocity jet by water-jet pump, its advantage is that antiseptic property is superior, long service life, easy to maintenance, its shortcoming is tighter to the requirement of water temperature, that is to say: obtain high vacuum, must keep water temperature in certain temperature, excess Temperature vacuum declines very fast.
Mainly contain at present two kinds of modes and reduce water temperature: 1, add back cooling water (its shortcoming is very large to the waste of water resource) 2, in the water tank of water injection vacuum unit, add heat exchanger.
The heat exchanger that can be added in now in the water tank that water sprays vacuum unit mainly contains two kinds: 1, graphite modified polypropylene circular pipe-coiled pipe formula heat exchanger.Major defect: it is limited that water sprays vacuum unit water tank capacity, coil exchanger is that rigid pipe forms, volume is large, the heat exchange area that can hold in unit volume is little, wall thickness comparatively speaking, sprays in vacuum unit and uses graphite modified polypropylene circular pipe-coiled pipe formula heat exchanger heat transfer effect undesirable at water; 2, graphite modified polypropylene finned heat exchanger.Major defect: 1, solder joint is many; 2, fin radiator is that injection molding forms, and the entity of its fin part, has increased thickness, and the finned loose heat transfer effect of graphite modified polypropylene of unit are is not too desirable, and the heat exchange area that reaching ideal effect needs is imitated large, and cost is higher.
Summary of the invention
Defect and deficiency that the utility model exists in order to solve above-mentioned prior art, provide in a kind of unit volume that heat exchange area is large, good effect of heat exchange, and the plastic alloy heat exchanger tube that wall thickness, cost are low and apply the heat exchanger of this heat exchanger tube, and the water-saving of applying this heat exchanger tube sprays vacuum unit.
The technical solution of the utility model: a kind of plastic alloy heat exchanger tube, comprise body, described body is flexible hose, and the inner surface of tube wall of body and the equal concave-convex surface of outer surface, described tube wall surface is heat dissipating layer.
Preferably, the thickness of described tube wall is 0.2-2mm, and described internal diameter of tube body is 5-50mm.
Preferably, described concavo-convex be square concave-convex shape, waveform is concavo-convex, disc is concavo-convex, thread-shaped is concavo-convex.
A kind of heat exchanger, comprise plastic alloy heat exchanger tube, housing and be arranged on the some import and export on housing, described import and export comprise that heat transferring medium is imported and exported and cooling medium is imported and exported, described plastic alloy heat exchanger tube is stayed in inner walls from top to bottom, and matches in the position that the end positions up and down of plastic alloy heat exchanger tube is imported and exported with cooling medium.
The utility model is all arranged to concavo-convex by heat exchanger tube body inner surface and outer surface, strengthen the heat exchange area of heat exchanger in unit volume, and adopt plastic alloy material entirety to make, without solder joint, heat exchanger tube wall thickness simultaneously, internal diameter of tube body is little, can make the heat exchanger tube setting of staying, thereby strengthens heat transfer effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but is not the restriction to the utility model protection domain.
A plastic alloy heat exchanger tube as shown in Figure 1, comprises body 1, and body 1 is flexible hose, and tube wall 2 inner surfaces of body 1 and the equal concave-convex surface of outer surface, and the thickness of tube wall 2 is 0.2-2mm, and described internal diameter of tube body is 5-50mm.
On the basis of foregoing, describedly concavo-convexly comprise square concave-convex shape, waveform is concavo-convex, collar plate shape is concavo-convex, screw thread is concavo-convex and square concave surface and the combination of waveform convex surface concavo-convex.
As shown in Figure 2, a kind of heat exchanger, comprise plastic alloy heat exchanger tube 8, housing 3 and be arranged on the some import and export on housing 3, import and export comprise heat transferring medium import 6, heat transferring medium outlet 7, cooling medium import 4 and cooling medium outlet 5, plastic alloy heat exchanger tube 8 is stayed from top to bottom on housing 3 inwalls, and the end positions up and down of plastic alloy heat exchanger tube 8 matches with the position of cooling medium outlet 5 and cooling medium import 4.
Heat exchanger tube of the present utility model can be applicable to water and sprays vacuum unit, as shown in Figure 3, vacuum unit comprises that the vavuum pump 9, water pump 10 and the water tank 12(12 that connect by pipeline do not mark out on picture), the heat exchanger 11 being made up of heat exchanger tube 8 is arranged in water tank 12.
It is primary raw material that heat exchanger tube of the present utility model adopts PP or PE, play the effect of anticorrosion and bonding other composition, add graphite or copper powder in order to increase heat conductivility, adopt extrusion process to make simultaneously, the pipe of extruding is shaped again with mould, pipe surface after sizing is concaveconvex shape, has following benefit:
1. the surface of concave-convex type can strengthen the intensity of heat exchanger, thereby can reduce the thickness of heat exchanger, increases heat transfer effect;
