Characteristics of the plate heat exchanger compare the housing heat exchanger

<p>Characteristics of the <a href="https://www.empireheatexchanger.com/products.html" target="_blank">plate heat exchanger</a> compare the housing heat exchanger</p><p><br></p><p>1. High heat transfer coefficient, because different corrugated panels are inverted each other, constitute a messy flow path, so that the fluid is rotating 3D activity in the corrugated plate flow path, which can be at a lower Renault (usually RE = 50 ~ 200) Turbuce occurs, so heat transfer coefficient is high, usually considered to be 3 to 5 times the housing type.</p><p><br></p><p>2. The aligned temperature difference is large, and the end temperature difference is small in the housing heat exchanger. The two fluids are active in the pipe and the shell, and is generally misal. Most of the heat absorber is more conternity or countercurrent activity, and the coefficients are also typically at 0.95, in addition, cold and hot fluids are parallel to the heat transfer surface, there is no stream, so that the temperature difference of the <a href="https://www.empireheatexchanger.com/products.html" rel="noopener noreferrer" target="_blank"><strong>plate heat exchanger</strong></a> is made parallel. Small, the water exchange heat can be less than 1 ° C, and the housing heat exchanger is usually 5 ° C</p><p><br></p><p>3. Small area, compact the plate heat exchanger, the heat exchange area in the unit volume is 2 to 5 times the housing type, and it is not necessary to reserve the maintenance venue of the pipette as a housing, thereby achieving the same The heat transfer amount is about 1/5 to 1/8 of the plate heat exchanger covers an area of ​​a housing heat exchanger.</p><p><br></p><p>4. Simply change the thermal area or process combination, just add or reduce a few panels, you can reach the purpose of adding or cutting heat exchange area; change the sheet to place or replace a few sheets to reach the required Process combination, habits new heat exchange conditions, while the heat transfer area of ​​the housing heat exchanger is not possible to add.</p><p><br></p><p>5. Light weight, the plate heat exchanger is only 0.4 to 0.8 mm, and the heat exchange tube of the housing heat exchanger is 2.0 to 2.5 mm, and the housing type housing is specific sheet heat exchanger. The structure is much more, and the plate heat exchanger typically requires only 1/5 of the shell component.</p><p><br></p><p>6. Low price, use the same material, under the same heat exchange area, the plate heat exchanger quotation is about 40% to 60% lower than the shell shell.</p><p><br></p><p>7. Manufacturing, the heat transfer plate of the plate heat exchanger is the use of stamping processing, the standardization is high, and can be produced in a large number of production, and the housing heat exchanger is usually manufactured in craftsmanship.</p><p><br></p><p>8. Simple cleaning, the structural plate heat exchanger only needs to loosen the bolt, which can loosen the plate, and remove the chassis for mechanical cleaning, which is very convenient for the heat exchange process of the equipment often cleaning the equipment.</p><p><br></p><p>9. Small heat loss, the plate heat exchanger only heats the heating plate of the outer shell plate to expose in the atmosphere, so the heat dissipation loss can be ignored, nor does it require insulation. The heat loss of the housing heat exchanger is large and the heat insulating layer is required.</p><p><br></p><p>10. Small capacity is 10% to 20% of the housing heat exchanger.</p><p><br></p><p>11. The pressure loss of the unit length is large, since the gap between the heat transfer surface is small, and there is a high low in the heat transfer surface, which is larger than the pressure loss of the conventional smooth pipe.</p><p><br></p><p>12. Not easy to foul, because internal abundance, it is not easy to foul, its fouling coefficient is only 1/3 to 1/10 of the housing heat exchanger.</p><p><br></p><p>13. Working pressure should not be too large, the medium temperature should not be too high, the plate heat exchanger selection seal seal, the working pressure is usually less than 2.5 MPa, the medium temperature should be below 250 ° C.</p><p><br></p><p>14. Easy to block, because the inter-board channel is narrow, usually only 2 to 5 mm, when the heat transfer medium is rich in larger particles or fiber substances, blocking the plate channel.</p>
