Making material thermal coefficient of expansion difference it is larger, cause PTC electric heater energization dry combustion method and power-off ventilation process in there may be
Abnormal sound, noise.On the other hand, because existing PTC electric heater is complicated, the material category used is more, and technological process is more multiple
It is miscellaneous, cause to manufacture cost height.
Utility model content
The purpose of this utility model is to provide a kind of PTC electric heater, it is intended to add for solving currently used PTC electricity
After hot device is powered thermal loss is big and heater is asked in energization dry combustion method and power-off ventilation process there may be abnormal sound, noise
Topic.Simplify the structure of PTC electric heater simultaneously, reduce production process arrangement, reduce manufacturing cost.
To realize above-mentioned utility model purpose, 1. a kind of PTC electric heaters that the utility model is provided, it is characterised in that：
Including PTC heater elements and being arranged on the outermost radiating aluminum strip of PTC heater elements；Up and down outside two of the PTC heater elements
Surface is respectively connected with electrode by bonding silica gel, and the inner surface of the electrode sticks in one with the PTC heater elements outer surface
Rise, the electrode outer surface is sticked together by the silica gel that insulate with the radiating aluminum strip, after energization, the PTC heater elements
The heat of generation passes sequentially through cohesive silica gel, electrode, insulation silica gel and radiating aluminum strip and transmitted.
Further, the cohesive silica gel size is adapted with the electrode inner surface size, and laminating completely.
Further, the insulation silica gel size is adapted with the electrode outer surface size, and laminating completely.
Further, described PTC heater elements are at least provided with 1.
Further, described PTC heater elements are provided with 3, and the inner surface of an electrode is by bonding silica gel
Outer surface with 3 PTC heater elements is mutually be bonded.
Further, the radiating aluminum strip and pole piece are provided with two panels, and the radiating aluminum strip passes through SOI glue sticking
In pole piece outer surface, pole piece described in two is sticked together by bonding silica gel with 3 PTC heater elements respectively.
The beneficial effects of the utility model are：Using insulating, electrode and radiating aluminum strip are bonded together by silica gel, are simplified
The structure of existing PTC electric heater, reduces production process arrangement, reduces heater and manufacture cost.Meanwhile, gram
Existing PTC electric heater has been taken in energization dry combustion method and power-off ventilation process there may be the problem of abnormal sound, noise, has been powered
Afterwards, thermal loss is small, excellent electrical properties.
