Description

The not charged ceramic heating of heat-flash type

The utility model relates to a kind of heating element, the not charged ceramic heating of particularly a kind of heat-flash type, and it mainly is adapted at being used as thermal source in the electric heater units such as air-conditioner, dryer, warm-air drier and bathroom heater.

Aluminium ripple ceramic heating element of the prior art is the heating element comparatively widely that uses at present, its structure as shown in Figure 1, it is made up of banded heat sink strip I ＇, ceramic heating plate 1 ＇ and socket 2 ＇, ceramic heating plate 1 ＇ is between banded heat sink strip I ＇, ceramic heating plate 1 ＇ can arrange continuously, and socket 2 ＇ are positioned at the end of ceramic heating plate 1 ＇; And banded heat sink strip I ＇ comprises corrugated plain fin I ＇-1, fin dividing plate I ＇-2 and fin seat I ＇-3, corrugated plain fin I ＇-1 is positioned at fin dividing plate I ＇-2 and fin seat I ＇-3, and this fin I ＇-1 contacts with the top of fin seat I ＇-3 and is the line contact; During use, be connected, make banded heat sink strip I ＇ heating and give out heat by ceramic heating plate 1 ＇ then by socket 2 ＇ and power supply; Though the heating element of this structure has many advantages, but its most fatal in actual use shortcoming is a surface charging, so it is just more worried to lack the words that child is arranged in security, the especially family when using in household electrical appliance, so surface charging has become the big hidden danger in its use; Simultaneously, be the line contact because the straight formula fin of ripple contacts with the top of fin seat, so its area of dissipation is little, straight formula fin does not have broken wind film and flow-disturbing function, and thermal efficiency conversion is poor; Socket 2 ＇ structural designs are unreasonable, and the scope of application is narrow.

The purpose that the utility model proposed can be achieved through the following technical solutions: this heating element comprises banded heat sink strip and ceramic heating plate, its design feature is that said banded heat sink strip is made up of offset strip fin radiator and fin seat, fin top in this offset strip fin radiator is the plane, and it contacts with the face of being connected to of fin seat; Be provided with heat-generating pipe, this heat-generating pipe is between two banded heat sink strips, and heat-generating pipe comprises said ceramic heating plate, conducting strip, insulator and outer tube, and insulator is between conducting strip and outer tube; Be provided with power supply and draw seat, it is connected with heat-generating pipe, and this power supply is drawn seat and comprised fire-retardant body and inserts, and inserts is fixed on the fire-retardant body, and is connected with contact on this inlay.

The head of fire-retardant body of the present utility model can be designed to taper, so that be installed in the heat-generating pipe easily.

The inlay that the utility model is fixed on the fire-retardant body can be one, also can be two, and this depends primarily on user's requirement, by accepting or rejecting the requirement that inserts reaches energising of heat-generating pipe one end or two ends energising.

The utility model compared with prior art, have the following advantages and effect: 1, reasonable in design, owing to adopted the structure of built-in ceramic heating plate of aluminum pipe and external insulation, thereby made heat-generating pipe not charged fully, improved its security in household electrical appliance use; 2, design has power supply to draw seat, has made things convenient for user's selectivity in use, and applicability is wide; 3, adopt the dislocation type fin structure, the fin top is the face contact with contacting of fin seat, in equal volume, improved area of dissipation greatly, simultaneously, because the dislocation on the fin structure is arranged, the wind film can't be generated, reduce thermal resistance, and can make air-flow disturbance in radiator, fully carried out heat exchange, the thermal efficiency is improved greatly, played heat-flash, effect efficiently.

Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.

Referring to Fig. 2, the utility model is mainly drawn an III by banded heat sink strip I, heat-generating pipe II and power supply and is formed, and the heat-generating pipe II is between two banded heat sink strip I, and power supply is drawn an III and linked to each other with the heat-generating pipe II; Banded heat sink strip I comprises offset strip fin radiator I-4, fin dividing plate I-2 and fin seat I-3, offset strip fin radiator I-4 fixedly forms by soldering between offset strip fin radiator I-4 and the fin seat I-3 between the fin seat I-3 or between fin seat I-3 and the fin dividing plate I-2; Fin dividing plate I-2 can not established yet, and offset strip fin radiator I-4 directly is welded on the heat-generating pipe II.

In addition, need more powerful heating element as the user, then also can be in the banded heat sink strip I of the utility model outside fixedly heat-generating pipe II and banded heat sink strip I again, to satisfy powerful needs, i.e. multilayer design as required.

Referring to Fig. 3, Fig. 4, offset strip fin radiator I-the 4th of the present utility model is combined by offset strip fin I-4-1, this offset strip fin I-4-1 top is the plane, it contacts with the face of being connected to of fin seat I-3 (see figure 2), thereby increased area of dissipation greatly, because this offset strip fin I-4-1 structure is arranged for dislocation and is formed, thereby air is flow to after the offset strip fin radiator I-4 can't regular motion, form flow-disturbing, also because structural dislocation is arranged, the wind film is constantly broken in the metal surface simultaneously, the wind film can't form, greatly reduce thermal resistance, improved heat exchanger effectiveness.

Referring to Fig. 5, heat-generating pipe II of the present utility model mainly is made up of ceramic heating plate II-1, conducting strip II-2, insulator II-3 and outer tube II-4, conducting strip II-2 is positioned at the skin of ceramic heating plate II-1, insulator II-3 is between conducting strip II-2 and outer tube II-4, thereby make outer tube II-4 surface not charged, guaranteed the security that whole ceramic heating uses in household electrical appliance.

Referring to Fig. 6, power supply of the present utility model is drawn an III and is made up of fire-retardant body III-1 and inserts III-2, and inserts III-2 is fixed on the fire-retardant body III-1, and is connected with contact III-3 on inserts III-2; Be installed in (referring to Fig. 2) in the heat-generating pipe II easily for making this power supply draw an III, the head of fire-retardant body III-1 can be designed to taper III-1-1.

Referring to Fig. 7, this is that power supply is drawn an III one end embodiment in when energising, can find out that from present embodiment it is that the inserts III-2 that conducting strip II-2 in the outer tube II-4 and power supply are drawn in the III is connected that power supply is drawn one of effect of an III, forms conductor; Two of effect is an III (with the sealing seat IV) to be drawn with power supply in outer tube II-4 two ends seal by high-temperature insulating glue, makes the interior element protection against the tide of outer tube II-4, dustproof, improves service life, and has guaranteed that the heat-generating pipe II is not charged; As customer requirements one end energising, then the power supply of heat-generating pipe II one end is drawn two inserts III-2 should be installed on the III, assembly spare not on the sealing seat IV of the other end; Power supply is drawn III insert in the heat-generating pipe II and connect, can play the purpose of end energising with conducting strip II-2.

Referring to Fig. 8, as customer requirements two ends energisings, as long as draw at power supply respectively adorn an inserts II-2 on the III, direction is located at the two ends of heat-generating pipe II on the contrary, and connects conducting strip II-2 respectively, has promptly reached the purpose of two ends energisings.
