Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an integral coil-type main heat exchanger. Background Technology

[0002] Heat exchangers are widely used in our lives, especially in industry. There are many types of heat exchangers, one of which is the coil heat exchanger. A heat exchanger (also called a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Traditional coil heat exchangers are exposed during use and lack effective protection mechanisms. This often leads to damage to the coil heat exchanger due to adverse external factors. At the same time, scale buildup occurs during use. If the scale is not removed in time, it will directly affect the heat exchange efficiency of the heat exchanger and reduce the efficiency of the device. Therefore, we have redesigned an integrated coil heat exchanger. Utility Model Content
