Specific embodiment

Embodiment one

As shown in Figure 1-3, energy-saving heating body structure described in the utility model embodiment one, including heater 1, the hair Hot body 1 has the cover for making heating target bottom form full encirclement or semi-surrounding, which is adjacent to the outer of heating target Wall surface and 1 bottom centre of heater is made relative to heating target at least to there is one to conduct heat to leading for the heating target Heat structure, the conductive structure include the aluminium dish 13 of 1 outer bottom of thermally conductive inner bottom surface and heater of heater 1.

Further, to improve contact surface of the aluminium dish 13 relative to heating target, the aluminium dish 13 is except outer edge setting Except one ring shape outer, remaining disk is disposed as the heat-conducting part 15 for being raised in 13 upper surface of aluminium dish of high uniformity, should Heat-conducting part 15, which opens up, is arranged heat-generating pipe 11 below several through-holes and one of through-hole.

Influence of 11 positional relationship of heat-generating pipe to heating target for above-mentioned setting is further analyzed:

Relationship between heat-generating pipe 11 and heat-generating disc as used by conventional means is usually to be adjacent to fixation, i.e. heat-generating pipe All in corresponding heat-generating disc bottom surface, the shape of soldering is different for soldering for 11 efficient heat generation face, have arc, rectangle, circle and Triangle, although heating efficiency is very nearly the same, different shapes can be used for implementing making to generate heat for different demand for heat Face different location thermal conductivity of trying to get to the heart of a matter is different, and still, since the thermal loss that heat-generating pipe 11 generates is seldom, almost all passes through fever Disk is conducted to heating target, is in this way brought rapidly up heating target bottom surface, and its side wall surface then heat up it is lower compared with slow and thermal conductivity, It is unbalanced to lead to the problem of heat；For the technical problem, technical solutions of the utility model are annular by the heat-generating pipe 11 It is set to 13 bottom surface outer of aluminium dish and in addition to 11 both ends of heat-generating pipe, an at least segment length is not between 11 both ends of heat-generating pipe Less than the contactless pipeline section of 11 total length one third of heat-generating pipe, which does not connect directly with 13 bottom surface of aluminium dish Touching, different from 11 both ends of heat-generating pipe and part interlude, which is not brazed to 13 bottom surface of aluminium dish directly.

Further, in addition to above-mentioned contactless pipeline section, the heat-generating pipe 11 is brazed by aluminium flake 12 at 13 bottom of aluminium dish Be welded as a whole structure between face and the aluminium flake 12 and aluminium dish 13, thus, the heat-generating pipe 11 passes through aluminium flake 12 to aluminium dish 13 Heat is directly conducted, which transmits heat to heating target again；

Influence of the positional relationship to heating target for the contactless pipeline section of the heat-generating pipe 11 is further analyzed:

Aluminium cover 14 is set below the heat-generating pipe 11 and the aluminium cover 14 closes 1 bottom of heater, thus in heater 1 One thermal conductive cavity is formed on bottom, which covers all the surrounding of heat-generating pipe 11 and aluminium cover 14 and aluminium dish 13 is closely pasted It is combined, the heat generated in the thermal conductive cavity is mainly derived from the heat that the contactless pipeline section of heat-generating pipe 11 generates, reason Be, 14 central part of aluminium cover have a thermal conductivity region to 1 bottom surface direction indent of heater, the thermal conductivity region with it is non- Contact pipeline section directly contacts, so that the heat for generating contactless pipeline section is thermally conductive by thermal conductivity region progress, to make Heat is transferred to entire aluminium cover 14 by the thermal conductivity region of the indent, and the partial heat for accumulating aluminium cover 14 passes to aluminium dish 13 again, The heat that heat-generating pipe 11 is come out in this way would not be lost, and be turned back back to aluminium dish 13, can not only improve the thermal efficiency, and most The loss of heat is reduced to limits, and also reduces the air themperature inside heating target；

Meanwhile the partial heat of the accumulation of aluminium cover 14 also passes through at 1 bottom edge of heater and 1 side wall of heater Face is directly conducted to heating target, so that heating target bottom center, edge, side wall is made to form balanced heating wire side, from And the whole heating efficiency of heating target is improved, and food caused by concentrating because of heating target bottom surface excess calories can be prevented Heat uneven, easy the problems such as burning.

Embodiment two

As shown in Figure 1-3, energy-saving heating body structure described in the utility model embodiment two, opposite to improve aluminium dish 13 In the contact surface of heating target, 13 disk of aluminium dish is uniformly arranged several bar shapeds and interconnected is raised in table in aluminium dish 13 The heat-conducting block in face.

Technical solutions of the utility model use the heat-generating pipe 11 of arc and are positioned in 13 bottom surface outer of aluminium dish, the hair An at least segment length is not less than the contactless pipeline section of 11 total length one third of heat-generating pipe between 11 both ends of heat pipe, this is non-to connect Touch pipeline section does not contact directly with 13 bottom surface of aluminium dish；

Correspondingly, be arranged below the heat-generating pipe 11 aluminium cover 14 and the central part have one to 1 bottom surface side of heater The thermal conductivity region to concave, the thermal conductivity region and contactless pipeline section close to but be not directly contacted with, to make contactless pipeline section The heat of generation preferentially pass through the thermal conductivity region carry out it is thermally conductive, so that heat be made to be transferred to entire aluminium by the thermal conductivity region of the indent Cover 14, make aluminium cover 14 accumulate heat pass through at 1 bottom edge of heater and 1 side wall surface of heater be directly conducted to heat pair As.

Accordingly for aluminium flake, heat-generating pipe and aluminium dish fixed structure can refer to embodiment one or on its basis into Row improves, and details are not described herein again.
