Embodiment 1

[0038] This embodiment combines figure 1 For illustrating the making of electric heater of the present invention:

[0039] Step 1. Provide a square frame, 7 corrugated aluminum cooling strips, and provide 6 aluminum square tubes and multiple PTC thermistors, and install the multiple PTC thermistors on the six Six heating elements are formed in the aluminum square tube;

[0040] Step 2. Use the sandblasting process to perform sandblasting treatment on the surface of the aluminum square that is connected to the heat dissipation strip to form the first sandblasting surface; the sandblasting process uses compressed air as the power to spray the spray material to the surface to be treated at high speed , the pressure of the compressed air is 4Kg / m 2 , the spray material uses quartz sand, the particle size of the quartz sand is 40 microns, the purity is higher than 99.5%, and the flow rate of the quartz sand is 1.0m 3 / min;

[0041] Step 3. The 6 heating elements and the 14 heat...

Embodiment 2

[0043] The manufacturing method of the electric heater in embodiment 2 is basically the same as that in embodiment 1, the difference is that step 2 also includes sandblasting the surface of the heat dissipation strip used to connect with the aluminum square to form a second sandblasting process by using a sandblasting process. surface; step 3, heat-conducting silica gel is arranged between the first sandblasting surface of the aluminum square tube and the second sandblasting surface of the adjacent heat dissipation strip, and the electric heater A2 is obtained by the manufacturing method of Example 2.

Embodiment 3

[0045] The manufacturing method of the electric heater of embodiment 3 is basically the same as that of embodiment 1, the difference is that the number of corrugated aluminum heat dissipation strips provided in step 1 is 7, and the number of adjacent two heating elements in step 3 is One heat dissipation strip is provided, and one heat dissipation strip is provided between the outermost heating element and the frame, and the electric heater A3 is manufactured by the manufacturing method of Example 3.

Abstract

The invention provides an electrical heater, comprising a frame, wherein multiple heat sink strips and multiple heating elements are arranged in the frame side by side, multiple heat sink strips and multiple heating elements are arranged at intervals, multiple heating elements comprise aluminum square tubes and PTC (positive temperature coefficient) thermistors installed in the aluminum square tubes, the aluminum square tubes are used for forming a first sandblasted surface with the surface which is connected with the heat sink strips, a thermal conductivity silica gel is arranged between the first sandblasted surface of the aluminum square tube and the adjacent heat sink strip, the aluminum square tube and the heat sink strips are bonded together by the thermal conductivity silica gel. The invention also provides a method for fabricating the electrical heater. The electrical heater has strong bond strength and good bond effect between the aluminum square tube and the adjacent heat sink strip, so that the heat conducting performance between the heating elements and the heat sink strips is excellent, the heat dissipation effect of the heat sink strips is good, and the frost removing, mist removing and heating effect are not affected even when the vehicle is used under the bumpy road condition for a long term.

Description

technical field [0001] The invention relates to the field of heaters, more specifically, to an electric heater, a manufacturing method thereof, and an automobile. Background technique [0002] In fuel vehicles, the defrosting and heating of the car in winter use an independent heat source (fuel) heating system or a waste heat (using engine cooling water or waste heat of exhaust gas) heating system. These two kinds of car heating and heating systems all need to rely on the engine of the car, that is to say, the defrosting, defogging and heating in the car can only be implemented when the engine is working. Heating is also impossible. In addition, the heating efficiency of this heating system is very low, and its structure is relatively complicated. It takes 6-10 minutes to supply heat after starting the engine in winter, especially for defrosting. The defrosting of the front windshield of the car requires the engine to work for a period of time. The heat can only be supplie...
