Description

Technical Field

[0001] The utility model relates to the field of heat exchangers, in particular to a heat exchanger which is convenient for defrosting. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers. When the surface temperature of the heat exchanger is lower than the outside temperature and lower than degrees Celsius, frost will form on the outer surface of the heat exchanger, which will reduce the heating performance of the heater. To ensure the heating performance, defrosting is required. The existing heat exchangers have a slow heat exchange speed, are inconvenient for defrosting, and are inconvenient for collecting and cleaning the crushed ice after defrosting, which has brought certain adverse effects on people's use process. For this reason, we propose a heat exchanger that is easy to defrost. Utility Model Content
