For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.
Embodiment 1:
In conjunction with Fig. 1 and Fig. 2, the engine charge heater of the new structure that the utility model provides comprises drawer type framework 10, PTC ceramic heating flake 11, radiating piece 12 and link 13.Wherein, PTC ceramic heating flake 11, radiating piece 12 and link 13 all are fixed in the drawer type framework 10.PTC ceramic heating flake 11 interfixes with radiating piece 12 and constitutes heating element 14.
In the utility model, heater adopts PTC ceramic heating flake 11, and it mainly is made of barium-titanate material, and its heating property has PTC (positive temperature coefficient resistor) characteristic.Two largest face of every PTC ceramic heating flake 11 are electrode surface, and electrode surface is done aluminium-plated processing.The back of aluminizing, the surface of PTC ceramic heating flake 11 welds together with the radiating fin (aluminium flake) of metal, makes it contact close and firm more, helps the conduction of heat and distributes.
The maximum initial inrush current 20A of every PTC ceramic heating flake 11, its Curie temperature are generally T ± 10 ℃ (general 140 ℃～230 ℃ of the scope of T).Under 25 ℃ of the normal temperature, reach the time≤20S of Curie temperature when applying voltage rating.Under voltage rating, the electric current≤0.3A when reaching Curie temperature, maximum voltage proof are equivalent to 2 times of voltage rating, and the flatness of two electrode surfaces generally is controlled at≤0.02mm.
As shown in Figure 2, radiating piece 12 comprises first aluminium flake 120 and second aluminium flake 121, and wherein, second aluminium flake 121 is bent into the Z font, to increase heat diffusion area.As shown in Figure 2, two first aluminium flakes 120 are fixed in the jut of second aluminium flake 121 by soldering processes.Can guarantee the uniformity and the soundness of its welding like this, solder joint is firm, the non-loosening phenomenon.
The surfacing of first aluminium flake 120 and second aluminium flake 121, surface imperfection such as non-oxidation, no burr, corrosion, the thickness of aluminium flake material generally is controlled at t=0.3mm～0.8mm, this thickness can be regulated according to the needs of radiating condition and cold-starting power, and the planeness of surface of contact is generally wanted≤0.1mm.
In the present embodiment, in order to improve radiating effect, the heating element 14 at drawer type framework 10 middle parts adopts the combination that is fixed with two groups of radiating pieces 12 between two PTC ceramic heating flakes 11.And select one group of radiating piece 12 for use with the PTC ceramic heating flake 11 of the junction of drawer type framework 10.
The high-performance PTC glue of function of use silicone grease between second aluminium flake 121 of above-mentioned PTC ceramic heating flake 11 and radiating piece 12 (Liyang Condar Nanjing University board) is bonding, after put baking oven baking into, under 180 ℃ of left and right sides temperature, toasted 80～120 minutes, before advancing baking oven, clamp, and guarantee bonding firm with special fixture.By soldering and bonding technology radiating piece 12 and PTC ceramic heating flake 11 are combined into different size and shape like this.
For making the utility model in use form closed current loop, and can satisfy the Placement of every PTC ceramic heating flake 11 parallel connections, also need link 13 various piece to be connected by the termination of radiating piece 12.First aluminium flake 120 and link 13 can be connected in the mode of pressing particularly.
