AI Technical Summary
Existing electric heating devices in heating, ventilation and/or air conditioning systems inside motor vehicles face space constraints and the need to reduce device size while preventing electric arc formation.
Design an electric heating device in which a printed circuit board is arranged close to a flow chamber, and the distance between the flow chamber and the printed circuit board is ensured to be less than 3.6 mm by means of cuts on the printed circuit board and the cooperation of a pad-like object. Thermally conductive materials and an elastic band are used to press against the electronic switch to avoid the formation of electric arc.
This achieves a reduction in the overall size of the electric heating device while preventing the formation of electric arcs, thus ensuring the safety and efficiency of the device.
