Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange equipment, and particularly relates to a stainless steel heat exchange tube. Background Art

[0002] The heat exchange tube is one of the key components of the heat exchanger. The following is a detailed introduction to the heat exchange tube: The heat exchange tube is placed inside the cylinder and is used to exchange heat between two media. It has high thermal conductivity and good isothermal properties. It can quickly transfer heat energy from one point to another with almost no heat loss. Therefore, it is called a heat transfer superconductor.

[0003] The problems of heat loss caused by exposed heat exchange tubes and only one heat exchange and low efficiency can be described in detail from the following aspects: If the heat exchange tubes are exposed and there are no proper insulation measures, heat loss will occur. This is because there is a temperature difference between the surface of the heat exchange tubes and the surrounding environment. Heat will be transferred to the surrounding environment through heat conduction, heat convection and heat radiation. Specifically: Heat conduction: The heat on the surface of the heat exchange tube will be directly transferred to the surrounding medium (such as air, water, etc.) in contact with it through the tube wall material. Heat convection: If the surrounding medium is a fluid (such as air), the heat will be transferred with the flow of the fluid. Heat radiation: The heat exchange tube will also be transferred in the form of Heat is radiated to the surrounding space in the form of electromagnetic waves. The loss of heat will cause the heat transfer efficiency of the heat exchanger to decrease, and more energy will be consumed to maintain the required temperature difference, resulting in energy waste. The heat exchange tube can only perform heat exchange once and has low efficiency. The heat exchange tube is usually designed for one-way or two-way flow, which means that the fluid can only perform heat exchange once or twice in the heat exchange tube. This design limits the heat transfer efficiency because when the fluid flows in the heat exchange tube, its temperature will gradually change with the transfer of heat. When the fluid flows out of the heat exchange tube, its temperature has approached or reached a thermal equilibrium state. At this time, if it is used for heat exchange, the efficiency will be greatly reduced. Utility Model Content
