Abstract
Description
Technical Field

[0002] Plastic products generally contain moisture and must be dried during production, otherwise it will cause defects such as material spots on the product.
[0003] The heater has the following features: 1. It has automatic constant temperature function and semiconductor ceramic heater. When the temperature exceeds a certain level, its resistance value increases stepwise with the increase of temperature, the power decreases, the temperature remains constant, no temperature control device is required, and the service life is long; 2. It does not turn red when working, there is no open flame, it can be dry-burned, it is easy to use, safe, and energy-saving; 3. It has a wide range of functions, such as: hair straighteners, curling irons, wax melters, thermos cups, milk warmers, coffee heaters, laminating machines, hot melt glue guns, shoe dryers, hand / foot warmers, massagers, chocolate machines, physiotherapy devices, etc.
[0004] At present, the common heaters on the market have a relatively simple structure, in which a heating resistor wire is inserted into the heat dissipation shell. The radiator shell is usually made of aluminum to achieve a higher industrial heat conduction speed. However, the aluminum material also expands and contracts with heat, causing the radiator shell to deform significantly. Repeated use during the injection molding machine's material drying process can easily lead to the heater being scrapped. In addition, the heat generation and heating efficiency of a single radiator shell are both low, which also reduces energy utilization. Utility Model Content
