The Heat Exchanger is mainly composed of many single heat pipes in the process of manufacturing. The number of heat pipes mainly depends on the size of heat exchange. In order to improve the heat exchange coefficient of gas, the method of adding fins to the pipes is often adopted, which can greatly reduce the number of heat pipes required. Integral heat pipe heat exchanger is mainly divided into gas-gas type, gas-steam type and gas-liquid type.
Heat pipe type gas-gas heat exchanger is mainly composed of shell, heat pipe elements and cold and hot fluid inlet and outlet interfaces. The shell is a steel structure, one side is a hot fluid channel, the other side is a cold fluid channel, and the center is separated by a tube plate. Insulation layers are arranged between the upper and lower orifice plates of the shell and the cover plate and on both sides of the equipment. The upper and lower cover plates are of removable structure, which is convenient for maintenance and replacement of heat pipes.
The heat exchanger is mainly composed of two parts when it is manufactured, the heat pipe steam generator and the steam water separation equipment. The heat pipe evaporation generator is a new type of evaporation equipment, which uses the heat pipe with excellent heat conduction function as the heat transfer element. High frequency welded fins are selected in the heating section of the heat pipe to enhance heat transfer. Therefore, the whole set of equipment has high heat transfer efficiency, compact equipment structure, and small resistance of hot fluid movement. Moreover, the existence of the heat pipe makes the heating and vaporization of water end outside the flue, and the separation of steam and water ends in the steam drum. This is different from the general flue type waste heat boiler. At the same time, the water sleeve and the steam drum are connected by pipes. The length of the pipes can be adjusted at will, and the on-site installation is sensitive. The whole set of equipment has no rolling parts, and the operation is reliable and the operation and repair are convenient.
Industrial Finned Tubes are different from domestic ones in that they do not excessively pursue beautiful appearance, and more requirements are better performance and longer service life, and they are selected according to regions and places of use.
1: Security
No matter what the scene and purpose, when selecting finned tubes, it is necessary to select finned tubes with high safety performance, and first select finned tubes that can ensure the safety of people and property.
2: Durability
For plants with particularly serious ash deposition, such as iron and steel plants and industrial kilns, large fin pitch shall be selected for heat exchange of finned tubes to minimize the loss of finned tubes, so as to maximize the durability and service life of finned tubes.
The medium temperature of the heat exchanger depends on the process conditions, and the medium temperature cannot be too high or too low, so scaling may occur,
Precipitation, crystallization and other phenomena may worsen heat transfer, so we should have a reasonable utilization temperature. The temperature difference at the hot end shall not be less than 20
The temperature difference at the cold end shall not be less than 5 ° C. the initial temperature of the condensing agent in the cooler shall be higher than the freezing point of the cooled fluid. If
It is the solidification of the gas without solidifying property. The temperature of the condensing agent should be five degrees Celsius lower than that of the solidified gas, and the Wenchang of the air should not be less than
Determine the heat transfer required for finned tubes
The first step is to determine how much heat transfer is required and how many heat transfer surfaces are required. This will help determine which type of Fin Tube is the best heat dissipation solution, including the necessary fin surface requirements and the ideal material. What fin tube geometry is needed to achieve your vision?
You should also determine the necessary flow rate, which will affect the required diameter of the finned tubes. Which is affected by the pipe size.
how much pressure drop is required?
what hydraulic diameter is required?
what is the flow length on each fluid side of the heat exchanger?
what is the minimum free flow area?
what do you need in the forehead area?
what is the flow length on each fluid side of the heat exchanger?
Heat transfer can be improved by increasing the number of tubes or increasing the length of finned tubes.
