Heat exchanger manufacturer _ Heat exchanger It is a device that transfers part of the heat from a hot fluid to a cold fluid. That is, water or other media is placed in a large, sealed container, and pipes pass through the container, allowing hot water to flow through the heat exchanger pipes. Heat exchanger manufacturer _ Heat exchanger Due to the temperature difference between the hot water in the pipe and the cold water in the container, heat exchange, or thermal equilibrium, will occur. Heat always transfers from a high-temperature object to a low-temperature object. In this way, the heat from the water in the heat exchanger pipe is exchanged to the cold water in the container. Heat exchangers are also known as heat transfer devices. _ Heat exchanger unit _ Heat exchanger unit manufacturer _ Which heat exchanger unit is the best? _ Water supply equipment _ Reverse osmosis device _ Environmental protection engineering
Heat exchanger manufacturer _ Heat exchanger The relative flow direction of the fluid generally includes two types: co-current flow and counter-current flow. In co-current flow, the temperature difference between the two fluids gradually decreases along the heat transfer surface, with a large temperature difference at the inlet and a small temperature difference at the outlet. Heat exchanger manufacturer _ Heat exchanger In counter-current flow along the heat transfer surface, the temperature difference between the two fluids is more uniform. Under the condition that the inlet and outlet temperatures of the cold and hot fluids are constant, when both fluids have no phase change, the average temperature difference in counter-current flow is larger than that in co-current flow. Heat exchanger manufacturer _ Heat exchanger Under the condition of completing the same amount of heat transfer, using counter-current flow can increase the average temperature difference, reduce the heat transfer area, and save equipment costs; if the heat exchanger uses counter-current flow, the heat transfer area remains unchanged, and the consumption of heating or cooling fluid can be reduced, saving operating costs. Therefore, counter-current heat exchange should be used as much as possible in design or production. _ Heat exchanger unit _ Heat exchanger unit manufacturer _ Which heat exchanger unit is the best? _ Water supply equipment _ Reverse osmosis device _ Environmental protection engineering
During phase change, only latent heat of vaporization is released or absorbed. When one or both of the cold and hot fluids undergo a phase change, the temperature of the fluid itself does not change, so the inlet and outlet temperatures of the fluid are equal, and at this time, the temperature difference between the two fluids is irrelevant to the choice of flow direction. Heat exchanger manufacturer _ Heat exchanger In addition to co-current and counter-current flow, there are also cross-flow and folded flow. _ Heat exchanger unit _ Heat exchanger unit manufacturer _ Which heat exchanger unit is the best? _ Water supply equipment _ Reverse osmosis device _ Environmental protection engineering
