Specific embodiment
In conjunction with referring to figs. 1 to 5, according to an embodiment of the invention, a kind of electric heater, including heat-dissipating pipe 1 and hair
Hot core assembly, the fever core assembly are located in the heat-dissipating pipe 1, and the tube wall of the heat-dissipating pipe 1 is equipped with drainage hole 9, are used
The water in the heat-dissipating pipe 1 is penetrated into discharge.
Fever core assembly is the major function part of electric heater, is powered and generates thermal energy, is dissipated in time by external heat-dissipating pipe 1
Calorific value；Heat-dissipating pipe 1 is generally such as aluminum pipe metal tube, and drainage hole 9 is arranged on aluminum pipe wall, infiltration aluminum pipe can be discharged in time
Interior water avoids ponding excessive and penetrates into fever core assembly, causes short circuit phenomenon to electrode；9 knot of drainage hole is used simultaneously
Structure can facilitate internal heat dissipating.
For convenient for being discharged into the water in aluminum pipe as early as possible, drainage hole 9 is equipped with multiple；Especially, drainage hole 9 is distributed in
The both ends of heat-dissipating pipe 1 and/or middle part.
Specifically, fever core assembly includes fever tablet 11, potsherd 12 and electrode strip 13, there are two electrode strip 13 is set, and
Row's setting；Fever tablet 11 and potsherd 12 are located between two electrode strips 13；There are two potsherd 12 is set, fever tablet 11 is located at two
Between a potsherd 12.Fever tablet 11 be equipped with it is multiple, be arranged among potsherd 12, mainly play heating functioin；Both ends arrangement pottery
Tile 12, is mainly used for heat-blocking action；Zero firewire electrode item 13 of two sides is bonded fever tablet 11 and potsherd 12 by silica gel
On electrode strip 13, a set of fever core assembly is formed.
Wherein, width of the electrode strip 13 at potsherd 12 is less than the width at fever tablet 11, passes through subcontract electricity
