Therefore, more and more companies have begun to pay attention to energy saving and consumption reduction. Therefore, many companies have begun to develop energy-saving and consumption-reducing products. For the plastic machinery industry, the advantages of high-efficiency energy-saving heaters are obvious.
[0003] In the existing heater, when heating, the heat generated by the heating wire cannot be well taken away by the fan because the heat dissipation area of the U-shaped heating tube surface is small. After working for a period of time, the surface of the U-shaped heater tube will oxidize due to excessive temperature, which greatly reduces its heat dissipation performance and greatly increases energy consumption. Due to poor heat dissipation, the local temperature on the surface of the heater tube is high. After a long time, the heating wire will break due to aging, so its service life is generally very short. Therefore, the utility model proposes an energy-saving heater for a dryer to solve the above problems. Utility Model Content
