Hunan around the plate heat exchanger supplier

Is part of the heat exchanger heat transfer fluid to cold fluid, the fluid temperature reaches a predetermined process heat exchange equipment index, also known as heat exchangers. Category recuperative heat exchanger of the present editor metal segment jacketed heat exchanger of this type of heat exchanger is installed in the outer wall of the container jacket is made of a simple structure; however, it is limited by the heating surface of the container wall, pass heat transfer coefficient is not high. To improve the heat transfer coefficient and heat evenly so that the liquid in the kettle, the agitator can be installed in the tank. When the jacket of the cooling water or heated without phase change agent, also the jacket Set screw separators or other measures to increase turbulence, improve heat transfer coefficient to the side of the jacket. to supplement the heat transfer surface, can also be installed in the flexible tube inside the autoclave. jacket-type heat exchangers are widely used in the reaction process The heating and cooling. Immersion coil heat exchanger that is bent around a metal pipe and a container adapted into a variety of shapes, and immersed in the liquid in the container. Coil heat exchanger advantage of simple structure, able to withstand high pressure, Available corrosion-resistant material; the drawback is the low degree of turbulence in the liquid in the container, a small tube heat transfer coefficient to improve the heat transfer coefficient can be mounted blender container. This spray heat exchanger heat transfer tubes in rows is fixed on a steel frame, thermal fluid flow within the pipe, cooling water from the sprinklers evenly pour over the next, it is also known as spray cooler . spray-type heat exchanger tube is a high degree of turbulent layer film, tube heat transfer coefficient than the immersive increased a lot. In addition, such heat exchangers are mostly placed in ventilation place, cooling evaporation of water also take some heat, it can serve to reduce the cooling water temperature, increase the heat transfer driving force of action. Therefore, as compared to immersion, spray-type heat exchanger heat transfer effect of the greatly improved. Tube heat exchanger tube heat exchanger is made directly into the control of different diameters concentric tube, connected together by a U-shaped bend in such a heat exchanger, a fluid take the tube, another A fluid go annulus, both can give higher flow rates, so the heat transfer coefficient is large. In addition, the tube heat exchanger, the two fluids may be pure countercurrent, logarithmic mean greater impetus. Tube heat exchanger structure is simple and can withstand high pressure, applied also to facilitate (increase or decrease the number of pipe sections as needed), especially due to the heat exchanger casing along with the heat transfer coefficient, heat a large driving force and can withstand high pressures advantages in the production of ultra-high pressure process (e.g., an operating pressure of 3000 atmospheres pressure polyethylene production process) used in almost all heat exchanger tube type. Plate heat exchanger: plate heat exchanger definition map of the most typical recuperative heat exchanger, it is used in industry has a long history, but still all the heat exchanger dominate. The main structure of the strip and plate heat exchanger plates between components. Long dominated the market, but its bulky, low heat transfer efficiency, replace expensive tape (tape replacement cost approximately 1 / 3-1 / 2 of the process) is mainly used in liquids - liquids heat exchange between, often referred to as the industry water of heat, the heat transfer efficiency in 5000w / m2.K. To improve the heat transfer coefficient of fluid tube, usually mounted transverse baffle baffle a number within the housing. Baffle baffle only prevents fluid short circuit, increase the fluid velocity, also forcing the fluid path many times as required by cross-flow tube bundle, so that greatly increased the degree of turbulence. Commonly have a moon-shaped baffle and a disc-shaped two, the former more widely used ..
