Description

Efficient laminated heat exchanger

Technical field

The utility model relates to a kind of new type heat exchanger, particularly relates to a kind of efficient laminated heat exchanger.

Background technology

Heat exchanger is the equipment partial heat of hot fluid being passed to cold fluid, also known as heat exchanger.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial department, occupies critical role aborning.In Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., applies more extensive.Heat exchanger kind is a lot, but substantially can divide three major types namely according to the principle of cold and hot fluid exchange heat and mode: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, dividing wall type heat exchanger application at most.

Wherein double pipe heat exchanger has some outstanding advantages, so be still widely used in the industrial departments such as petrochemical industry so far, advantage mainly comprises:

1. structure is simple, and heat transfer area increase and decrease freely.Because it is combined by standard element, without the need to other processing during installation.

2. heat conductive efficiency is high.It is a kind of pure adverse current type heat exchanger, and can also choose suitable sectional dimension, to improve fluid velocity, increase the heat transfer coefficient of two side liquids, therefore its heat-transfer effect is good simultaneously.During liquid-liquid heat exchange, heat transfer coefficient is 870 ~ 1750W/ (m 2 DEG C).This point is particularly suitable for the heat exchange of high pressure, low discharge, low heat transfer coefficient fluid.The shortcoming of double pipe heat exchanger is that floor space is large; Unit heat transfer area metal consumption is many, and pipe joint is many, easily leaks; Flow resistance is large.

3. structure is simple, and work accommodation scope is large, and heat transfer area increase and decrease is convenient, and two side liquids all can improve flow velocity, make the both sides of heat-transfer area can have higher heat transfer coefficient; Shortcoming is that the metal wastage of unit heat-transfer area is large, and maintenance, cleaning and dismounting all comparatively bother, and easily cause leakage in releasable connection place.Be bent into stacked spiral-shaped casing main body together with wearing copper pipe in it and restraining, and weld with bushing type main body with the fixed support of steel and consolidate shaping, sleeve pipe two ends are derived cold-producing medium separately and are connected set pattern with cooling water.

There is a kind of efficient laminated heat exchanger at present on the market, and its advantage adopts measurements of the chest, waist and hips heat exchange new technology, make the cold and hot transmission highly significant of water and refrigerant, it is a new generation of heat exchanger, but the place of its still Shortcomings, its heat exchange area is still not enough to ensure that refrigerant can heat exchange cmpletely relative to the area of light pipe, there is certain design not enough.
