In order to solve the technical problem, the utility model discloses a waterproof overhead PTC heater, including the core body that generates heat and with the insulating base that the core body cooperation was installed that generates heat, the core body that generates heat passes through insulating base and installs in the installation frame, and the protection network is installed at the top of installation frame, and the aluminum pipe oral area packing of the core body that generates heat has the sealing compound to form secondary seal in order to realize preliminary sealing and through the casting glue between the tip of insulating base and the core body that generates heat.
And sealing rubber rings are sleeved at the end parts of all the aluminum pipes of the heating core body.
The end of the conducting wire in the aluminum pipe of the heating core body is sleeved with a silica gel sealing ring.
The mounting frame is made of aluminum magnesium alloy materials.
And a rubber pad is arranged at the bottom of the insulating base.
The lead of the heating core body is sleeved with a silica gel sheath and then is led out from the installation frame.
The strip-shaped hole grooves are opposite to the heat dissipation strips of the heating core body, and the connecting ribs formed between every two adjacent strip-shaped hole grooves are opposite to the aluminum pipes of the heating core body.
The utility model has the advantages of:
on the basis of pouring sealing glue at the opening part of the aluminum pipe of the heating core body, the protection grade of the heating core body is improved by secondary pouring glue between the heating core body and the insulating base, meanwhile, the designed protective net plays an all-round protection role in the vertical direction of the heating core body, and particularly, the ventilation area is increased under the condition that the strength of the protective net is ensured to the maximum extent by the rectangular hole grooves designed on the protective net; furthermore, under the original size and power of the heater, the rubber pad is arranged at the bottom of the insulating base, and meanwhile, the mounting frame is made of an aluminum-magnesium alloy material, so that the problems that the internal structure of the PTC heater is changed, the electrical safety performance of the electric heater is reduced and even the electric heater fails due to vibration or bumping impact are effectively solved, the overall weight is reduced by about 10% -20% on the basis of the traditional product, the design can fully ensure that the product has good waterproof performance, and the electrical performance safety of the overhead PTC heater is also improved.

Detailed Description
The waterproof overhead PTC heater of the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
As shown in the figure, the utility model discloses a waterproof overhead PTC heater, including heating core body 1 and the insulating base 2 installed with the heating core body, heating core body 1 is installed in the installation frame 4 through the insulating base 2, wherein, heating core body 1 adopts the conventional structure, it includes the aluminum pipe with built-in electrode and the fin set outside the aluminum pipe, mentioned in this embodiment, install two heating core bodies 1 side by side in the installation frame 4, the tails of two heating core bodies 1 are all supported through a tail insulating base as tail (outside end) support, the medial extremity (connecting end) of two heating core bodies 1 is supported through a middle insulating base located in the middle of the installation frame 4 for supporting two heating core bodies, the bottom of the middle insulating base and two tail insulating bases are all installed with a rubber pad 10 with a thickness of 4mm, therefore when the heating core body and the installation frame are assembled, can play a shock absorption role by increasing the installed rubber pad, the top of the installation frame 4 is provided with two protective nets 5, two protective nets 5 respectively correspond to one of the heating core body 1, play a protective role in the vertical direction of the heating core body, each heating core body and the protective net can form a shock absorption role through the sealing glue, the sealing between the two insulating bases and the sealing base, the sealing structure is realized through the sealing structure between the aluminum pipe and the aluminum pipe 2, can adopt almag material to make with installation frame 4 and still satisfy the operation requirement, simultaneously, can become 15mm by original 24mm with heating core body thickness, the aluminium pipe becomes 20mm by original 24mm in the heating core body to make the product subtract about 10% -20% with the unchangeable condition of size and performance, its protection level is: IP68 (namely, after the heater is soaked in a pool with the depth of 1M for 24H, the performance of the test appliance reaches the design requirement).
Furthermore, the rectangular hole grooves for ventilation are distributed on the protective screen 5, the rectangular net grooves are opposite to the heat dissipation strips of the heating core body 1 so as to facilitate ventilation, the connecting ribs formed between the adjacent rectangular hole grooves 7 are opposite to the aluminum pipes of the heating core body 1, and if the connecting ribs cannot be opposite to the aluminum pipes, the effect of protecting the heating core body of the PTC heater cannot be achieved, so that the ventilation area is increased under the condition that the strength of the protective screen is ensured to the maximum extent through the designed rectangular hole grooves.
