What Is Effect Of Bar Plate Heat Exchanger On Compressor?

A heat exchanger is a common and important part of the compressor. Today we talk about bar plate heat exchanger, a lot of the heat exchanger used in screw compressor, piston compressor, wind power equipment and various kinds of engineering machinery, etc., application is very extensive.

We know that the equipment in the process of running through the friction heat, the heat without cooling treatment, will damage to the device itself form, caused the accident. So heat exchanger is one of the most commonly used parts on many devices, the bar plate heat exchanger is made mainly of aluminum.

On the compressor, the heat exchanger is mainly made of copper pipe, and the cooling mode is generally cold and cold. Air cooling is in commonly 10 cubic relatively common screw compressor, water-cooled generally more common in more than 10 cubic model, sometimes also can see air-cooled models on 20 cubic model. Water-cooled machine mainly is circulating water cooling medium, but generally older models have few advanced circulating water filtering device, so there will be some impurities into the heat exchanger of compressor, the formation of scale, its congestion, lose heat exchanger, and the recent new models after added filtering tank device, can effectively filter out the impurities in the circulating water part.

Main heat exchanger tube heat exchanger, finned heat exchanger, shell and tube heat, bar plate heat exchanger, displacement heat exchanger, plate heat exchanger, double tube plate heat exchanger, etc., each have each advantages and USES the heat exchanger. In these types of heat exchangers, bar plate heat exchanger is a type of market that is favored by the market. But the bar plate heat exchanger is something that you're not familiar with, and as a user needs to have a new understanding of it.

The main structure of a bar plate heat exchanger

The bar plate heat exchanger is mainly composed of plates and fins, and other parts have plates, seals, guides, distribution segments, seals and beams.

Its working principle is the partition and fin and seal components such as a unit body, these units can be in series with the body, according to customer demand, the complexes of different sizes, let medium through combination of imported into, and then from exports. For example, the air and water of the compressor go all the way, and the water absorbs some of the heat from the hot air, reducing it to cool.

From the structural analysis of the bar plate heat exchanger, the technique of this heat exchanger is the seal, and if the seal is not strict, the gas water can leak. Therefore, sealing is critical, and the requirement for material is relatively high. Another benefit is that the pipeline is maximized and more uniform, which is conducive to improved thermal efficiency.

The type of bar plate heat exchanger is rich also, now we are seeing are: flat, zigzag, corrugated shape, porous, blinds, etc.

The advantages of bar plate heat exchanger

1. In high thermal efficiency, according to its structure, fin area is small, thin volume, easy to heat conduction, heat dissipation can quickly go out, is the ideal way of heat dissipation.

2. Compact structure, can make full use of space, save materials, reduce cost, at the same time can free combination according to user needs and the loading and unloading, self-regulation, but can small, can be in series, can also be parallel, applicable to a variety of media at the same time, practical and convenient.

3.The manufacturing process is precise, because it is required to be tightly sealed, so it has a high working standard. Because once the leakage occurs, it is difficult to find the leak. Another to corrosion resistance also to have certain request, because the main material is aluminum bar plate heat exchanger materials, aluminum alloy material with poor oxidation resistance, easy to corrosion, as a result, fluid with high acid composition such as, the material easy to corrosion of aluminum quickly. Industrial fluid material, however, the general situation of acid fluid have been diluted, able to quickly get aluminum corrosion of possibility is very small, therefore, under normal circumstances, bar plate heat exchanger is safe.

4.Widely used, bar plate heat exchanger is mainly used in air separation equipment, most of which can be used in compressor. Because it has a flexible volume change, so the heat exchange efficiency is good some advantages, medicine, aviation, aerospace, automobile manufacturing, petrochemical, cryogenic refrigeration, engineering machinery, general machinery, etc.

Third, maintenance processing

Because of bar plate heat exchanger structure is flat and fin, the combination of the plate fastened together, if tight and tight, is prone to leakage, and leakage point is not easy to find. At the same time, due to the corrosive nature of the fluid, the pressure factors, the combination of pressure and leakage, are more likely to leak. The solution is usually to remove inspection and clean up, but the engineering cycle is longer, the labor is expensive, and there is a problem of shorter processing cycle. This will increase the maintenance cost and affect the operation of the equipment.

Now is in the repair process, the metal surface is coated with high temperature resistant corrosion resistant polymer composite material, the effective control of the fluid inside the heat exchanger of residues, can effectively block the leakage point.
