Abstract
The utility model discloses a heatproof sound-absorbing novel electronic pipe, successively comprising a heat dissipation sound-absorbing layer, an insulating layer and a pipe wall from inside to outside; the insulating layer is formed by ceramic high temperature resistance insulating materials and the heat dissipation sound-absorbing layer is manufactured by graphite milk materials. The heatproof sound-absorbing novel electronic pipe possesses good heat dissipation performance, excellent tone quality and beautiful profile and is easy to absorb secondary electrons generated in the electronic pipe.
Description
Technical field
The utility model relates to a kind of electron tube, especially relates to a kind of novel electron pipe of heat-resisting sound-absorbing.
Background technology
At present, the inside glass of the electron tube of applying on market, is mainly to produce next life and to do without coating and black coating, the electron tube of making like this, and internal heat dissipating conduction is poor; A little less than the absorption of the secondary generation electronics producing in electron tube, secondary electron can produce noise, affects the distinctive acoustical quality of discharge-tube amplifier; External form is without aesthetic feeling.Electron tube does not have good insulating properties, easily causes the resistance wire short circuit starting the arc under HTHP.
Utility model content
The purpose of this utility model is in order to overcome prior art deficiency, and the novel electron pipe of a kind of good heat dissipation effect, sound-absorbing insulation is provided.
The utility model is achieved by the following technical programs:
A novel electron pipe for heat-resisting sound-absorbing, comprises tube wall, insulating barrier and heat radiation sound absorbing layer, and described electron tube is from interior heat radiation sound absorbing layer, insulating barrier, the tube wall of being followed successively by outward.
Further, described insulating barrier is formed by a kind of ceramic material in aluminium oxide, magnesium oxide, titanium oxide.
Further, described heat radiation sound absorbing layer adopts aquadag material to make.
The beneficial effects of the utility model are:
(1) heat radiation sound absorbing layer of the present utility model adopts aquadag material to make, and has the features such as desirable tack, stable chemical nature, corrosion-free, nonhazardous; The thermal radiation capability of graphite is high, is sprayed on the insulating barrier of electron tube inwall, forms rough surface, is easy to the secondary electron producing in absorbe valve.With this kind of material spraying at electronic tube glass inwall, better radiations heat energy; Absorb better secondary electron, reduce electron tube because the noise that secondary electron produces; External form is novelty more attractive in appearance also.
(2) the utility model is provided with insulating barrier, described insulating barrier is formed by a kind of ceramic material in aluminium oxide, magnesium oxide, titanium oxide, effectively prevented that electron tube inwall is oxidized, simultaneously because insulating barrier has insulating effect under HTHP, can prevent the resistance wire short circuit starting the arc, greatly extend the useful life of electron tube.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model electron tube.
Fig. 2 is I place partial sectional view in Fig. 1.
In accompanying drawing: l-heat radiation sound absorbing layer, 2-insulating barrier, 3-tube wall.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described in detail.
As shown in Figure 1 and Figure 2, a kind of novel electron pipe of heat-resisting sound-absorbing, comprises tube wall 3, insulating barrier 2 and heat radiation sound absorbing layer 1, and described electron tube is from interior heat radiation sound absorbing layer 1, insulating barrier 2, the tube wall 3 of being followed successively by outward.
Described insulating barrier 2 is formed by a kind of ceramic material in aluminium oxide, magnesium oxide, titanium oxide.First by ceramic material liquefaction, then with the vaporific spraying method of high pressure, the ceramic material after above-mentioned liquefaction is sprayed on according to predetermined spray time on the inner surface of tube wall of electron tube, after dry sclerosis, forms insulating barrier 2.The thickness of insulating barrier 2 is about 10～60 microns, and the degree of the dielectric voltage withstand of electron tube is reached more than 300 volts.
Described heat radiation sound absorbing layer 1 adopts aquadag material to make.Employing high-carbon graphite is raw material, through ultramicro grinding and the high-purity micro-fine natural flake graphite powder that obtains be take water as carrier, adds suitable chemical assistant and the high degree of dispersion deflocculated graphite emulsion made.Above-mentioned aquadag is sprayed on the insulating barrier of electron tube tube wall, forms rough inner surface, be easy to the secondary electron producing in absorbe valve.Simultaneously aquadag has the features such as desirable tack, stable chemical nature, corrosion-free, nonhazardous, thermal radiation capability are high, perfect heat-dissipating.
It is to be noted; the utility model is not limited to above-mentioned execution mode; any simple modification, applied in any combination, equivalent variations and modification that any those skilled in the art do above-described embodiment in based on technical solutions of the utility model, all belong in protection range of the present utility model.
Claims (3)
1. a novel electron pipe for heat-resisting sound-absorbing, comprises tube wall, insulating barrier and heat radiation sound absorbing layer, and described electron tube is from interior heat radiation sound absorbing layer, insulating barrier, the tube wall of being followed successively by outward.
2. the novel electron pipe of a kind of heat-resisting sound-absorbing as claimed in claim 1, is characterized in that: described insulating barrier is formed by a kind of ceramic material in aluminium oxide, magnesium oxide, titanium oxide.
