Abstract

A plastic tube heat exchanger is coiled into a spiral, including an inner tube and an outer tube, wherein, the inner tube is a metal tube, the outer tube is a plastic tube, the inner tube is placed in the outer tube, and the inner surface of the outer tube is a smooth surface. Both ends (import and export) of the inner tube and outer tube are connected in a fluid circulating system of the equipment by welding, threaded or flange connection. The high-temperature medium enters form one end of the inner pipe, while the low-temperature medium enters the other end of the outer tube, they flows in counter direction to perform heat exchange. The utility model has advantages that: 1. as the plastic outer tube has a certain amount of flexibility, after inserting liquid in the outer tube and supplying a certain hydraulic pressure, the inner tube has no contact with the outer tube, so that the fluid channel is smooth; 2. the inner surface of the outer tube is smooth, has good circulation and small water resistance; 3. the corrosion-resistant plastic outer tube can be widely used directly for a variety of media, 4. the utility model has easy production, zero leakage in the product system, safety and reliability and reduced total cost of product (2/3).

Description

The plastic bushing heat exchanger
Technical field
The utility model relates to the components and parts of heat exchanger, promptly a kind of heat exchanger made from plastic bushing.
Background technology
At present in chilling units such as air-conditioning, the structure of double-tube heat exchanger comprises internal heat exchange tubes and outer sleeve, internal heat exchange tubes is a helical bundle structure made of copper, outer sleeve is a steel pipe, helical bundle is the center symmetric arrangement with the axis of outer sleeve, also be helical structure in each root heat exchanger tube, the high-temperature medium that flows in the interior pipe, the cooling liquid that flows in the outer sleeve carries out heat exchange.This double-pipe exchange has following shortcoming:
1, to the quality requirement strictness of the fluid of the cooling medium in the outer tube, generally all needs to carry out to use after the pre-treatment;
2, the resistance of fluid is big in the outer sleeve, is easy to fouling in pipe, and serious also occurring easily stopped up, and fluid resistance has greatly just increased the load of systemic circulation, and the fouling of tube wall also can influence heat exchange efficiency and service life with stopping up;
3, metal pipe-wall is not corrosion-resistant, can not use seawater, sewage etc. as cooling medium;
4, because the material of interior pipe, outer tube requires height, complex structure to cooling medium quality requirement height, so product price occupies height, has restricted popularization, the use of corresponding supporting unit.
Summary of the invention
For overcome present double-tube heat exchanger complex structure, cost an arm and a leg, resistance is big, easily fouling, to the high shortcoming of medium requirement, the utility model proposes a kind of new design of heat exchanger of outer effective plastic bushing.
This plastic bushing heat exchanger, the dish curl, pipe and outer tube is characterized in that interior pipe is a metal tube in comprising, and outer tube is a plastic tube, and interior pipe places outer tube, and outer tube wall is a shiny surface.
The two ends import and export of interior pipe and outer tube is connected in the fluid circulating system of equipment by welding, screw thread or ring flange.
High-temperature medium enters from an end of interior pipe, and cryogenic media enters from the other end of outer tube, and their reverse flow are carried out heat exchange, the utility model has the advantages that:
1, because plastic outer tube has certain flexibility, after injection liquid gave certain hydraulic pressure in outer tube, interior pipe did not contact with outer tube, makes the fluid passage unimpeded, and the medium heat-transfer surface is even, and the variation adaptability of outer tube convection cell operating mode is strong, can ensure the lasting thermal efficiency;
2, outer tube wall is smooth, and circulation is good, and water resistance is little, and the fluid stagnant area is very little, and is less scaling, long service life, and circulatory system load is little;
3, because plastics are corrosion-resistant, and outer tube can extensively directly use various media, the waste heat waste water in river, lake water, well water, seawater, regenerated sewage, industry, the life etc. all can be used as medium and uses; Interior pipe adapts to as media such as R22, R407, R410, high steams;
4, make easily, can reach zero in the product systems and reveal, safe and reliable, to compare with metal sleeve heat exchanger in the market, product always or originally can reduce by 2/3.

Fig. 2 is the utility model A-A profile
Among the figure: 1, interior pipe, 2, outer tube, 3, interior pipe import, 4, the outlet of interior pipe, 5, the outer tube import, 6, the outer tube outlet.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail as follows:
In Fig. 1 and Fig. 2, the utility model disc type helical form, pipe 1 and outer tube 2 in comprising, interior pipe 1 is a metal tube, outer tube 2 is a plastic tube, interior pipe 1 places outer tube 2, outer tube 2 inner wall smooths, the import and export at interior pipe 1 and outer tube 2 two ends is connected to by ring flange in the fluid circulating system of equipment, and high-temperature steam enters from interior pipe import 3, flow out from interior pipe outlet 4 the cooling back, cooling water enters from outer tube import 5, after being heated, flows out from outer tube outlet 6, high-temperature steam and cooling water reverse flow have been carried out convective heat exchange.
