[0002] Cast aluminum heaters are electric heaters that use tubular electric heating elements as heating elements and high-quality aluminum alloy materials as shells through die-casting. Their operating temperature is generally between 150 and 450 degrees Celsius. They can be widely used in plastic machinery, die heads, cable machinery, chemicals, rubber, petroleum and other equipment. Cast aluminum heaters have the characteristics of good thermal conductivity, light weight and durability, energy saving and high efficiency, safety and reliability. Cast aluminum heaters are widely used in the field of industrial heating and can meet the heating needs of different industries.

[0003] After searching, the patent publication number is "CN 212692493 U", which is a cast aluminum heater with a protective device, including a first outer shell and a second outer shell, a protective mechanism is arranged at one end of the first outer shell, the protective mechanism includes a connecting pipe, a sleeve is sleeved on the outer side of one end of the connecting pipe, a miniature cooling fan is connected to the inner end of the sleeve, a first through hole is opened on the front inner wall of the connection between the connecting pipe and the sleeve, and a second through hole is opened on the front inner wall of the connection between the sleeve and the connecting pipe, an opening is arranged on the inner side of the connecting pipe on the outer surface of one end of the first outer shell, and electric heating wires are arranged on the inner walls of the first outer shell and the second outer shell.

[0004] Further searching revealed that the purpose of the publication number "CN 208332878 U" is to cool the terminal blocks, avoid heat generation and temperature rise at the connection between the terminal blocks and the wires, and prevent the circuits from being burned. It has a good protective effect and is safer to use.

If multiple fans are set at the same time, not only will the power loss be large, but it will also cause difficulties in the subsequent maintenance and repair of the device. Therefore, it is urgent to design a heat dissipation protection device for the cast aluminum heater to solve the above problems. Utility Model Content
