The heat exchanger is a device that transfers part of the heat of the hot fluid to the cold fluid, also known as the heat exchanger. Heat exchanger occupies an important position in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.
1.The principle of different types of heat exchangers will be different. For example, the dividing wall heat exchanger, which is that two fluids with different temperatures flow in a space separated by a wall, through the heat conduction of the wall and the convection of the fluid on the wall. Heat exchange between fluids. Partition wall heat exchangers include shell-and-tube type, double-pipe type and other types of heat exchangers.
2.Body-connected indirect heat exchanger is a heat exchanger that connects two surface heat exchangers by a heat carrier circulating in it. The heat carrier circulates between the high-temperature fluid heat exchanger and the low-temperature fluid. Receiving heat, the low-temperature fluid heat exchanger releases the heat to the low-temperature fluid.
3.The compound heat exchanger has both steam-water surface indirect heat exchange and water-water direct mixed flow heat exchange equipment.Compared with steam-water surface indirect heat exchange, it has higher heat exchange efficiency; compared with steam-water direct mixing heat exchange, it has higher stability and lower unit noise.
