The threaded pipe, also known as the low-finned pipe, increases the internal and external area of heat exchange without increasing the external volume, thus improving the efficiency of heat exchange. Suitable for all kinds of heat exchanger. Such as air conditioning, various diesel engines, gasoline engine heat exchanger, thermal power plant, nuclear power plant heat exchange tube, loose heat pipe, boiler (or water heater) heat pipe, etc.
The inner and outer spiral pipe is mainly made into the pipe inside and outside the same spiral body, so that the heat source in the pipe body rotation under the action of the pipe spiral body, can make the heat source body for sufficient heat exchange, the cooling body outside the pipe will also be rotated around the pipe under the action of the spiral body, so that the cooling body is fully cooled. In addition, spirochaeta is also a heat exchanger, so it can improve the efficiency of the heat exchanger. Simple manufacturing structure.
Application description:
Internal and external spiral tubes can be used for various types of heat exchangers, because the structure of internal and external spiral tubes in the same appearance size, internal and external heat exchange area is large, so the efficiency of heat exchange is also large.
For example, when used in boiler (or water heater), because the contact surface of the inner surface of the heat pipe and the pipe wall is the interface of heat exchange when the heat pipe is heated, the water gas (steam) bubble is formed after heating, and the water gas (steam) bubble will increase with the increase of temperature. When the buoyancy of the water gas (steam) bubble is greater than the water pressure, the water gas (steam) bubble will break away from the pipe wall and float upward. The water vapor bubble leaves its original position in the wall and is replaced by new water. Do this repeatedly until the fire is turned off. A large number of water gas (steam) bubble floating will form water power, water power will drive the boiler water and upward flow, so that the boiler water is fully heated. This increases the rate at which water is heated, thus providing the efficiency of heat exchange
