The specific embodiment

In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Referring to Fig. 1-Fig. 3, a kind of heater, comprise heat generating components, outside interior pot 2, be arranged with a heat conduction aluminum pot 1, described heat conduction aluminum pot 1 is Split type structure with described interior pot 2, described heat generating components contacts with the outer bottom of described heat conduction aluminum pot 1, and described heat conduction aluminum pot 1 inner bottom surface contacts with described interior pot 2 outer bottoms, and heat conduction aluminum pot 1 sidewall and described interior pot 2 sidewall aspect ratios are 1/6-5/6.

When the bottom of interior pot 2 is placed on heat conduction aluminum pot 1 when interior, the inner bottom surface of heat conduction aluminum pot 1 contacts with the outer bottom of interior pot 2, the medial surface of heat conduction aluminum pot 1 is corresponding with the lateral surface of interior pot 2 bottoms, therefore, when heat generating components heating power, the heat that heat generating components produces passes to the bottom surface of heat conduction aluminum pot 1, by the bottom surface of heat conduction aluminum pot 1, be delivered to rapidly again the side of heat conduction aluminum pot 1, thereby make whole heat conduction aluminum pot 1 there is more uniform temperature, so heat conduction aluminum pot 1 just internally heat by bottom surface and the bottom of pot 2 simultaneously, and then make firing rate fast, heat transmits, heat energy effect is high, simultaneously, due to homogeneous heating, prevented the especially interior pot 2 of the poor thermal conduction such as pottery of interior pot 2() explosion.

Referring to Fig. 1-Fig. 3, outside described heat conduction aluminum pot 1, be provided with inner insulating layer 4, heat-insulation chamber in forming between described inner insulating layer 4 and described heat-conducting pot, described inner insulating layer 4 surrounds described heat generating components.In interior heat-insulation chamber, there is air, except the heat energy of conduction to interior pot 2, other heat energy of heat generating components through the bottom of aluminum pot toward external radiation to inner insulating layer 4, because the pyroconductivity of air is little, thereby interior heat-insulation chamber plays good heat-blocking action, be beneficial to making full use of of heat, thereby further improve firing rate.

Many in order to prevent that heat from dissipating at inner insulating layer 4, therefore thermal insulation layer Ying Yi little is advisable, can retain more heat like this, so when described heat generating components is arranged on described heat conduction aluminum pot 1 outer bottom, described inner insulating layer 4 is arranged on outside the outer bottom of described heat-conducting pot, referring to Fig. 1-Fig. 3, with respect to inner insulating layer 4, cover the situation of heat conduction aluminum pot 1 bottom surface and side, this covering among a small circle can retain more heat energy.

Referring to Fig. 1-Fig. 3, at described inner insulating layer 4 and heat-conducting pot, be also provided with outer thermal insulation layer 5 outward, between described outer thermal insulation layer 5 and described inner insulating layer 4, form outer heat-insulation chamber.The heat energy of inner insulating layer 4 and heat conduction aluminum pot 1 outer wall is given outer thermal insulation layer 5 toward external radiation, in outer thermal insulation layer 5, also has air, therefore still can as inner insulating layer 4, play further heat insulation effect, and then retains the heat energy of inner insulating layer 4 and heat conduction aluminum pot 1 outside.Double thermal insulation weakens leaking of heat greatly, reaches good effect of heat insulation.

Referring to Fig. 2, the top edge of described outer thermal insulation layer 5 contacts with the large chamfering place of heat conduction aluminum pot 1; Outer like this thermal insulation layer 5 volumes are little, be beneficial to and produce assembling, and cost is lower slightly.Certainly, outer thermal insulation layer 5 also can surround the whole of inner insulating layer 4, with reference to Fig. 3, and the heat energy that retains inner insulating layer 4 and heat conduction aluminum pot 1 outer wall as much as possible.

The top edge of outer thermal insulation layer 5 can contact also and can not contact with the top edge of heat conduction aluminum pot 1; When both do not contact, can prevent directly thermal insulation layer from aluminum pot is transmitted to of heat, effect of heat insulation is better; But, being generally structure more firmly and being convenient to assembling, both are set to contact.

The longitudinal section of described inner insulating layer, aluminum pot and outer thermal insulation layer all takes the shape of the letter U.The top edge of outer thermal insulation layer coordinates with the outside upper Surface Contact of heat conduction aluminum pot.

Inner insulating layer 4 and outer thermal insulation layer 5 can be fixed on through retaining mechanism the bottom of heat conduction aluminum pot 1.

With reference to Fig. 1-Fig. 3, described heat generating components comprises heat conduction disk body 31 and heat-generating pipe 32, and the outer bottom with described heat conduction aluminum pot 1 of described heat conduction disk body 31 contacts, and described heat-generating pipe 32 is connected with described heat conduction disk body 31.

Described heat conduction disk body 31 is contained on described heat conduction aluminum pot 1, and described heat-generating pipe 32 is contained on described heat conduction disk body 31.As adopt brazing mode by as described in 31 solderings of heat conduction disk body as described on heat conduction aluminum pot 1, described heat-generating pipe 32 solderings are on described heat conduction disk body 31.By soldering, can make the upper surface of heat conduction disk body 31 and the outer bottom of heat conduction aluminum pot 1 interpenetrate, make heat-generating pipe 32 and interpenetrate with the lower surface of heat conduction disk body 31, thereby make heat-generating pipe 32, heat conduction disk body 31 and heat conduction aluminum pot 1 form an integral body.And soldering does not need to destroy the overall structure of heat conduction aluminum pot 1, do not need to connect with connectors such as screw or rivets yet, just heat conduction disk body 31 and heat-generating pipe 32 can be fixedly mounted on the outer bottom of heat conduction aluminum pot 1, thereby make the compact conformation of this heater, integral body very attractive in appearance.

Referring to Fig. 4, described heat-generating pipe 32 is the round of a bending, and two cold junctions intersection dislocation are contained on described heat conduction disk body 31.The heat that can well guarantee heat conduction disk body 31, heat conduction aluminum pot 1 is even.

Referring to Fig. 1-Fig. 3, in described heat conduction aluminum pot 1 bottom, there is a downward groove 6, and have one for avoiding the through hole 7 of described heat conduction aluminum pot 1 bottom groove 6 in the middle of described heat conduction disk body 31.Groove 6 effects of heat conduction aluminum pot 1 are that (particularly ceramic inner vessel 2 bottoms have slight tenesmus in sintering procedure for fear of the outstanding position of Nei Guo 2 bottom centre, cause the center of ceramic inner vessel 2 bottoms to contact with heat conduction aluminum pot 1, and other position of ceramic inner vessel 2 bottoms is unsettled), make heat conduction aluminum pot 1 contact more abundant with interior pot 2 bottoms.Through hole in the middle of heat conduction disk body 31 is for avoiding the groove 6 of heat conduction aluminum pot 1.

The utility model, except the material of aluminium as heat-conducting pot, also can be used material that other thermal conductivity factor is high as the material of heat-conducting pot.

The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
