Tube heat exchanger

24-hour hotline 15360094527 spiral tube heat exchanger such as Germany specifically for small and medium refrigeration heat transfer equipment supporting the design, realization of different working conditions on both sides to strengthen efficient heat transfer medium. The product is a total of 27 models, cooling capacity from 2.6KW ~ 125KW. Because of its unique advantages, so the wind cold hot water unit, water source heat pump, water loop heat pump, household air conditioning, air-source heat pump water heaters and other refrigeration equipment are widely used. Optimized Design: spiral tube heat exchanger body made of high quality and efficient internal screw thread copper tubes, pipes composed of different coat, then a spiral structure overall. Helix bundle with the center axis of the outer pipe arranged symmetrically. This design allows the heat exchanger after forming each tube length, uniform distribution, heat transfer tubes of integrity and uniform heat transfer boundary. Refrigerant forced convection boiling heat transfer tubes in the cooling wall, circulating water in the tube bundle outer wall of strong convection and heat. In the joint action of the coil and the internal thread, secondary refrigerant circulating in the mainstream direction perpendicular to the inner tube. Constitute the gap between spiral and outer casing of complex shaped spiral flow path has two properties, both sides of the secondary circulation of the heat transfer has been significantly strengthened. Product Features: ★ designed, high-performance SCE series summarize existing tube heat exchanger design experience in domestic and international basis, through a large number of simulation and anatomical experiments on different models, application areas, use conditions, be a comprehensive series of optimized design, the structure is more reasonable, more excellent performance. ★ excellent selection, high reliability selected in line with internal heat exchanger GB / T8890--1998 high-walled lower rib thread copper, compared with the normal inner grooved copper tube heat transfer coefficient, corrosion resistance is strong, not because of the long-term run copper tube leakage caused by dangerous; the outer cannula according to different environments and application conditions, there is a fluid seamless pipe, stainless steel, brass, titanium tube options, the series pipe wall is smooth, high strength, corrosion-resistant strong, highly reliable long-term operation. ★ withstand shock, not deformed refrigeration system in actual operation due to temperature fluctuations, start-stop cycle, the heat pump defrosting, expansion valve adjustment and other complex factors affect, the internal pressure is always in frequent alternation process. At higher or frequent changes of pressure, pressure shock resistant helical bundle structure and ability to withstand pressure is much higher than the sheet structure. Therefore, the refrigeration system can adapt to the actual operating conditions of complexity. ★ dirt dirt-resistant, stable due to the spiral tube heat exchanger heat transfer tube bundle using specific spiral structure, which is designed so that the heat transfer tubes water side flow channel having a larger cross-sectional size, can tolerate greater water sand, fibers and other impurities by diameter, resulting in the possibility of blockage of the small, but because of the possibility of blockage caused by hard water is small, due to the long run and will not cause a substantial decline in heat transfer performance and waterways clogged, So meet the water quality tube heat exchanger stronger, stable and reliable system operation. ★ return oil smooth, safe refrigerant flow spiral tube heat exchanger, there is no significant increase in the flow channel, lubricating oil even in the case of small flow can be safely returned to the compressor, because the system will not lag oil heat transfer area leading to reduced resistance increases, running instability, destruction and other hazardous press. ★ technology is good, not easy to leak spiral tube heat exchanger in the process layout process, the less weld joints, Process easy, easy welding quality assurance, greatly reducing the system of long-term tolerance to vibration, pressure fluctuation, hot and cold Alternate impact as a result of the interface crack danger of leakage. ★ structure is flexible, easy to configure spiral tube heat exchanger can be any shape required by the designer, and installation size and import and export orientation can be freely changed according to the design requirements of the unit, while the interior has a large space can be arranged other refrigeration components , so better meet the needs of designers. ★ reduce costs, save costs due to the heat exchanger tube in the design process was the most cost-effective optimal allocation, and lower manufacturing costs. Users will be able to get a lower price of the same capacity heat exchanger. And compared with other heat exchangers, tube heat exchanger is much stronger than the other in pressure, earthquake, frost, clogging aspect, so it will not generate a lot of problems because of the quality of after-sales service costs during operation .
