Abstract
The utility model relates to an improved ceramic electric heater for fan, which comprises main components such as a ceramic thermistor (PTC ceramic for short), aluminum metal sheets, and an extended surface, wherein, the PTC ceramic sheet and the aluminum metal sheet are conglutinated by silica gel which adulterates electric metal powder. A pyrexia unit body is formed by that the extended surface between the upper aluminum metal and the lower aluminum metal, the upper aluminum metal, and the lower aluminum metal are welded into a whole with aluminum jointing. The pyrexia unit body is combined with a plurality of pyrexia unit bodies so as to provide a heat source for the electric heater for fan.
Description
The utility model system mainly is to provide a kind of assembling easy about a kind of ceramic Hot-air fan device of improvement, and the ceramic Hot-air fan device of the heat that resistance is distributed when not influencing it and conducting electricity.
The ceramic thermal element of popular in the market ceramic Hot-air fan generally adopts the fin of copper product or the fin of aluminum, owing to engage the silica gel that all uses insulation between potsherd and the fin, thereby influence the efficient of thermal element.
The purpose of this utility model provides a kind of simple in structure, the ceramic Hot-air fan device that easy to assembly and cost is lower.
Above-mentioned purpose of the present utility model reaches like this, a kind of ceramic Hot-air fan device of improvement, comprising up and down an aluminium flake and a fin, and several plane PTC potsherds, it is characterized in that aluminium flake welds fin with Al filler up and down, and make its fin the cambered surface apical margin can with aluminium flake conducting up and down (electric current), descend the side of aluminium flake again, directly glue together with the conduction silica gel with plane P RC potsherd.
Because the utility model is to adopt the silica gel of conduction to engage between potsherd and fin, thereby, the efficient of thermal element improved.
For making the auditor be easier to understand the device and the effect of the utility model, the spy is as follows with regard to description of drawings now:
Fig. 1 is the three-dimensional exploded view of the utility model heat-generating units body.
Fig. 2 is the plane of the utility model heat-generating units body.
Fig. 3 is the combination stereogram of the utility model.
Fig. 4 implements schematic diagram for the utility model.
See also Fig. 1, end is riveted with terminal 11 before wherein going up aluminium flake 1,2 one-tenth vertical neat rugosities of fin, its two ends reach 3 one-tenth fit shapes of aluminium flake down with last aluminium flake 1 respectively, promptly utilize on the fin 2 cambered surface 21 and lower camber side 22 respectively with upper and lower aluminium flake within the side with 25 welding of aluminium inserts, and the apical margin 23,24 of going up lower camber side also can with aluminium flake up and down be conducted (electric current).Two plane ceramic thermal resistances (being called for short the PTC potsherd) 4 can place down the appropriate location of aluminium flake 3 to be glued at down side under the aluminium flake 3 with conducting resinl 41 in addition, as shown in Figure 2.And form a heat-generating units body, again with identical mode of operation,, just can form PTC ceramic resistor heating group as shown in Figure 3 in conjunction with several cell cubes.When logical go up electric current after the heat of PTC ceramic resistor generation make the cold wind that passes through become hot blast to blow out; Thereby form a complete ceramic Hot-air fan (as Fig. 4).
Comprehensively above-mentioned, the utility model is a kind of simpler and easy, convenient package technique, can assemble in the short time and finish, and the ceramic Hot-air fan device of a lower cost is provided.
