The solid-state parallel heater of pulsation vacuum sterilizerTechnical field
The present invention relates to a kind of heater of carburator, especially a kind of solid-state parallel heater that is applied to pulsation vacuum sterilizer carburator.
Background technology
Pulsation vacuum sterilizer is to utilize saturated vapor when condensation, to discharge the physical characteristic of latent heat, the equipment that makes article subject to sterilization keep high temperature dampness to reach certain hour and carry out sterilizing, the effect of carburator is to provide high temperature saturated vapor for sterilizing, therefore, in pulsation vacuum sterilizer use procedure, require carburator to there is heat exchange rapidly and add heat-staple feature; And the pulsation vacuum sterilizer of selling in the market, its carburator or heat conduction efficiency are low, do not reach heat exchange requirement rapidly, or complex structure, bulky, and cost is too high, is all not suitable with market demand.
Summary of the invention
For solving the defect of above-mentioned prior art, the invention provides that a kind of volume is little, cost is low, simple in structure, heat exchanger effectiveness is high, the heating stable solid-state parallel heater of pulsation vacuum sterilizer rapidly.
For completing above-mentioned task, the technology of the present invention solution is achieved in that the solid-state parallel heater of a kind of pulsation vacuum sterilizer, it is characterized in that, the heating element heater of carburator be arranged in parallel with heat exchange element and shape identical, use the cast molding of solid state heat conductor between the two, and the distance of interval 10-60mm.
Heating element heater is cylindrical tube and identical with heat exchange element shape, and it is inner and be uniformly distributed that resistance wire is positioned at heating element heater, and with high temperature resistant, antioxidation, material filling that insulating properties is high.
Heat exchange element is hollow cylindrical, and internal diameter is 6-18mm, according to instructions for use, can be coiled into S type, Z-type or M type, can single arrangement, also can compoundly arranging, is that 200-1000J/ (kg ℃), corrosion-resistant, antioxidative metal material are made by specific heat capacity, and preferred material is rustless steel.
Solid state heat conductor adopts specific heat capacity at 200-1000J/ (kg ℃), corrosion-resistant, antioxidation and the easy solid-state material moulding by casting of processing, is preferably aluminium alloy.
Beneficial effect of the present invention is, heating element heater is identical with heat exchange element shape and be arranged in parallel, make both under the state of same volume, it is maximum that the ratio of corresponding parallel area reaches, and effectively increased heat exchange area, adopts little, the low density material of specific heat coefficient to make simultaneously, improve heat transfer efficiency and alleviated component weight simultaneously, have volume little, add thermally-stabilised, heat exchange advantage rapidly, and simple in structure, adapt to commercial production needs in enormous quantities.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 heating element heater, 2 heat exchange elements, 3 resistance wires, 4 solid state heat conductors.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Embodiment 1, the solid-state parallel heater of a kind of pulsation vacuum sterilizer, shown in Fig. 1, it is characterized in that, the heating element heater 1 of carburator be arranged in parallel with heat exchange element 2 and shape identical, use 4 cast moldings of solid state heat conductor between the two, and the distance of interval 10mm, heating element heater 1 is cylindrical tube and identical with heat exchange element 2 shapes, resistance wire 3 is positioned at heating element heater 1 inside and is uniformly distributed, and with high temperature resistant, antioxidation, the material that insulating properties is high is filled, heat exchange element 2 is hollow cylindrical, internal diameter is 6mm, according to instructions for use, can be coiled into S type, Z-type or M type, can single arrangement, also can compoundly arrange, by rustless steel, made, solid state heat conductor 4 adopts aluminium alloy moulding by casting, and this has formed a kind of structure of the present invention.
During energising work of the present invention, heating element heater rapidly by thermal energy transfer to solid state heat conductor, because adopting the solid-state material of less specific heat capacity, there is good heat conductivity, heat conductor again by uniform thermal energy conduction to heat exchange element, adding solid state heat conductor has certain energy storage, therefore have conduction of heat fast, add the advantages such as thermally-stabilised.
Embodiment 2, the solid-state parallel heater of a kind of pulsation vacuum sterilizer, shown in Fig. 1, basic identical with embodiment 1 structure, difference is, the heating element heater 1 of carburator be arranged in parallel with heat exchange element 2 and shape identical, use 4 cast moldings of solid state heat conductor between the two, and the distance of interval 60mm, heat exchange element 2 is hollow cylindrical, internal diameter is 18mm.
Embodiment 3, the solid-state parallel heater of a kind of pulsation vacuum sterilizer, shown in Fig. 1, basic identical with embodiment 1 structure, difference is, the heating element heater 1 of carburator be arranged in parallel with heat exchange element 2 and shape identical, use 4 cast moldings of solid state heat conductor between the two, and the distance of interval 40mm, heat exchange element 2 is hollow cylindrical, internal diameter is 12mm.
