Abstract
The utility model discloses a novel electric heater which is mainly used for a small absorption refrigeration mechanical generator. The utility model is characterized in that the novel electric heater comprises a two-piece semicircle metal column surface (the size of the metal column surface is suitable to the generator), an outside preparation insulated base layer and a ceramic mould electrothermal film which is acted as a pyrotoxin and is prepared on the base layer. The novel electric heater has the advantages of large heat transmission area, small heat transmission temperature difference, small size, low cost and convenient replacement.
Description
Traditional electrical heating method that is used on the absorption-diffusion type refrigerator three bushing type generators is divided into two kinds of external labeling type and interpolation types, but its characteristics all are to heat by heating wire heating power in the electrical bar as heater block with the common electrical hot pin.External labeling type is to add side by side outside the outer tube to weld a steel pipe similar with the electrical bar external diameter on generator, again electrical bar is inserted in the pipe, by steel pipe heat is passed to side by side generator outer tube, reach the purpose of solution in the heating muff.Because two garden pipe transmission of heat by contact area is less side by side, and it is bigger to heat the heat flow density of required transmission, and therefore electrical bar often reaches rubescent temperature (about more than 550 ℃) when work; For the generator outer tube, have only one-sided heat input in addition, very inhomogeneous.These make the generator steady operation unfavorable for economize on electricity, prolongation electrical bar life-span.Interpolation type is the generator outer tube with script garden cylindricality, change its shape, the embedded pipe of burn-oning, though can make homogeneous heating like this, but technology is comparatively complicated, especially for the generator sleeve pipe of internal high pressure, weld seam will increase, and bring certain difficulty to processing.
New type heater of the present utility model, adopt two thin-walleds (the semicircle type metal cylinder of thickness 0.5mm～2mm), internal diameter is identical with generator outer tube external diameter, the outside is after insulation is handled, press power demand, coat ceramic mould Electric radiant Heating Film (seeing application for a patent for invention 87103537 in addition), with clip or screw securing members such as (bolts) two semicircle type electric heating cylinders are buckled in tightly during use and are heated (on the generator) on the pipe fitting, reach good heating purposes (seeing accompanying drawing), this new type heater has following main feature.
1, two thin-walleds, the half garden metal cylinder of Electric radiant Heating Film circumferentially contacts with generator outer tube garden in the preparation, and contact area is big, and promptly heat transfer area is big, conducts heat evenly, and firing rate is fast, and mean temperature difference is little.
2, two-piece type half garden cylindrical structure and clip or screw securing members such as (bolts) flexibly can be installed easily, dismantle and change.
3, adopt this heater.Do not have additional technological requirement for manufacturing of generator, do not increase its technology difficulty yet, and can reduce weld seam, (this point benefits for the reliability of whole refrigerating core).
4 and traditional electric heating bar type heater littler than this heater assembly volume that takes up space, help insulation, install.
5, the Electric radiant Heating Film thermal capacitance is little, quick heating, and heating evenly and the combination of said structure characteristics has guaranteed the power saving of this heater, energy-conservation, advantage that the life-span is long.
6, this heater low cost of manufacture, and can require to make different tube diameters, length and power according to difference.
Description of drawings:
1, refrigerator generators is heated part;
2, electrode;
3, half garden metal cylinder;
4, insulating bottom layer;
5, Electric radiant Heating Film.
Embodiment:
Structure of the present utility model as shown in the figure.Two halves garden cylinder, inside radius 12.5mm, long 150mm, outside plating enamel and glass are insulating bottom layer (insulating properties reach national household electrical appliances examination criteria and international IEC standard), be the long 100mm of Electric radiant Heating Film in fact, power 70～80W uses pipe collar as securing member, be applicable on the three sleeve pipe generators of 50 liter small absorption household refrigerator-freezers, respond well.
Claims (2)
1, a kind of absorption-diffusion type refrigerating electric heater is characterized in that two semicircle type thin-wall metal cylinders, and outside preparation has Electric radiant Heating Film.The metal cylinder be heated circumferentially transmission of heat by contact of pipe fitting (generator outer tube).
2, absorption-diffusion type refrigerating electric heater as claimed in claim 1 is characterized in that, clamping connection can be used as the Electric radiant Heating Film input electrode with the metal intermediate plate.
