Description
Technical field
The utility model is related to the air heating apparatus of in-built electrical heated filament.
Background technology
Heating wire is widely used in heating device, such as air heating apparatus, but existing air heating apparatus is complicated, makes
With inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of air heating apparatus of in-built electrical heated filament, can heat air, and
It is easy to use.
To achieve the above object, the technical solution of the utility model is to design a kind of air heating dress of in-built electrical heated filament
It sets, including is vertically arranged cylindric cartridge heater, cartridge heater upper and lower ends opening；
The barrel of the cartridge heater is built-in with helical form heating wire, the helical form heating wire heart coaxial with cartridge heater；
The cartridge heater is internally provided with several heat conduction web plates, each heat conduction web plate heart coaxial with cartridge heater, and each heat conduction web plate
It is axially uniformly distributed along cartridge heater；Each heat conduction web plate and cartridge heater inner wall tight fit；
It is evenly equipped with several through-holes respectively on each heat conduction web plate；
Of vertically-adjacent two heat conduction web plates, their through-hole mutual dislocation.
Preferably, the heating drum outer wall is covered with thermal insulation layer.
The advantages of the utility model and advantageous effect are：A kind of air heating apparatus of in-built electrical heated filament, energy are provided
Air is heated, and easy to use.
Heating wire can heat cartridge heater, and then heat heat conduction web plate, the air in cartridge heater heated after by cartridge heater
Top exports, and air pressure decline, the hot-air to be added of cartridge heater bottom end vicinity can be automatically replenished into cartridge heater in cartridge heater, to
Form the lasting output of hot-air.
The through-hole mutual dislocation of vertically-adjacent two heat conduction web plates, is produced during air can be allowed to rise inside cartridge heater
Raw turbulent flow, improves heating effect.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
The utility model specific implementation technical solution be：
As shown in Figure 1, a kind of air heating apparatus of in-built electrical heated filament, including it is vertically arranged cylindric cartridge heater 1, cartridge heater 1
Upper and lower ends are open；
The barrel of the cartridge heater 1 is built-in with helical form heating wire, the helical form heating wire heart coaxial with cartridge heater 1；
The cartridge heater 1 is internally provided with several heat conduction web plates 2, each heart coaxial with cartridge heater 1 of heat conduction web plate 2, and each heat conduction
Web plate 2 is axial uniformly distributed along cartridge heater 1；Each heat conduction web plate 2 and 1 inner wall tight fit of cartridge heater；
It is evenly equipped with several through-holes respectively on each heat conduction web plate 2；
Of vertically-adjacent two heat conduction web plates 2, their through-hole mutual dislocation.
Preferably, 1 outer wall of the cartridge heater is covered with thermal insulation layer.
Heating wire can heat cartridge heater 1, and then heat heat conduction web plate 2, the air in cartridge heater 1 heated after by heating
1 top of cylinder exports, and air pressure decline, the hot-air to be added of 1 bottom end vicinity of cartridge heater can be automatically replenished into cartridge heater in cartridge heater 1
1, to form the lasting output of hot-air.
The through-hole mutual dislocation of vertically-adjacent two heat conduction web plates 2, during air can be allowed to rise inside cartridge heater 1
Turbulent flow is generated, heating effect is improved.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
