Description
Technical field
The utility model relates to a kind of heat pipe axle, more particularly, is that the heat pipe axle performance before a kind of ratio has larger improved Novel hot tubular axis.
Background technology
Electromagnetical blower fan is widely used exhaust or supercharging equipment in the industrial production, is specially adapted to the occasion that does not allow leakage such as poisonous, inflammable.Because general heat dissipating method all is to form the working heat that cross-ventilation is dispelled workpiece by the external fan air-supply, this process very easily causes work safety accident so that the motor of fan is exposed under the harsh operational environment.By built-in heat pipe axle, we can realize effective isolation of heat abstractor and exhaust (or supercharging device), thereby have guaranteed that electromagnetical blower fan can safe operation in poisonous, inflammable and explosive operational environment.Nearly six during the last ten years, and the combination of heat pipe and axle mainly is to occur with the form of rotating heat pipe, although solved sealing problem, radiating effect is not good, still has some problems during actual production.
The utility model content
For above-mentioned technical problem, the utility model is intended to solve the problems of the technologies described above at least to a certain extent.
The purpose of this utility model is to provide a kind of better heat-radiation effect, the Novel hot tubular axis of more realistic need of production.For achieving the above object, the utility model has adopted following technical scheme:
A kind of Novel hot tubular axis, comprise hollow shaft, be arranged at the first sealing plug and the second sealing plug that the hollow shaft two ends make the inner formation of hollow shaft closed cavity, described closed cavity is disposed with heat-absorbing chamber, transport chamber and the heat radiation chamber that is interconnected from left to right, the hollow shaft outer wall in corresponding described heat radiation chamber is provided with radiating fin, be filled with liquid working substance in the described closed cavity, be respectively arranged with the first keyway and the second keyway on the corresponding hollow shaft of described heat-absorbing chamber and transport chamber.
Further, described liquid working substance is water, ethanol.
Further, described heat radiation cavity wall in axial direction be provided with opening towards heat-absorbing chamber, taper value be 1 the degree the conical surface.
Further, the inwall of described heat-absorbing chamber is processed with internal thread vertically, in order to increase heat transfer area.
Further, the material of described radiating fin is the good materials of thermal diffusivity such as aluminium alloy, copper.
The amount of being filled with of described liquid working substance is that the factors such as density of the density of liquid working substance and saturated steam determine under the working temperature by the volume of the volume of liquid phase part, gas phase part.Described heat-absorbing chamber has screw thread, plays to increase endotherm area and guide functions, and action principle of the present utility model is: when the heat pipe axle was heated, heat was delivered in the heat pipe axle, and the screw thread of heat-absorbing chamber inwall has increased the area that conducts heat, thereby has strengthened rate of heat transfer.Be vaporizated into gas after internal liquid working medium is heated and flow to the heat radiation chamber by transport chamber, the air inlet cold wind outer by the heat pipe axle is condensed into liquid, and the radiating fin in heat radiation chamber increases the heat dissipation capacity in the unit are greatly, has also improved condensation effect simultaneously.The backflow of condensed fluid is mainly rotated the centrifugal force of generation along the component of heat pipe cavity inner wall face by means of axle, promotes heat radiation chamber liquid working substance and is back to heat-absorbing chamber along the heat pipe axial wall plane, forms the cyclic process with the continuous discharge of heat.
The utlity model has following beneficial effect:
(1) applied widely, can be used for electromagnetical blower fan etc. has the axle machine, strengthens radiating effect, plays airtight radiating effect;
(2) reduce energy consumption, improve energy utilization rate, reduce the heat radiation expense of equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Need to prove that accompanying drawing only is used for exemplary illustration, can not be interpreted as the restriction to this patent; To those skilled in the art, in the accompanying drawing some known configurations and explanation thereof may to omit be understandable.
As shown in Figure 1, a kind of Novel hot tubular axis, comprise hollow shaft 1, be arranged at the first sealing plug 2 and the second sealing plug 10 that hollow shaft 1 two ends make hollow shaft 1 inner formation closed cavity, described closed cavity is disposed with heat-absorbing chamber 5, transport chamber 6 and the heat radiation chamber 9 that is interconnected from left to right, hollow shaft 1 outer wall in corresponding described heat radiation chamber is provided with radiating fin 8, be filled with liquid working substance in the described closed cavity, be respectively arranged with the first keyway 3 and the second keyway 7 on described heat-absorbing chamber 5 and the transport chamber 7 corresponding hollow shafts 1.
Described liquid working substance is water, ethanol, closed cavity is pumped into 0.9 standard atmospheric pressure before being filled with a certain amount of liquid working substance to closed cavity.
It is the conical surface of 1 degree towards heat-absorbing chamber 5, taper value that described heat radiation chamber 9 inwalls in axial direction are provided with opening.
The inwall of described heat-absorbing chamber 5 is processed with internal thread 4 vertically.
The material of described radiating fin 8 is the good materials of thermal diffusivity such as aluminium alloy, copper.
The mechanism of this Novel hot tubular axis is: when the heat pipe axle was heated, heat was delivered in the heat pipe axle, and the screw thread 4 of heat-absorbing chamber 5 inwalls has increased the area that conducts heat, thereby has strengthened rate of heat transfer.Be vaporizated into gas after internal liquid working medium is heated and flow to heat radiation chamber 9 by transport chamber 6, the air inlet cold wind outer by the heat pipe axle is condensed into liquid, and the radiating fin in heat radiation chamber increases the heat dissipation capacity in the unit are greatly, has also improved condensation effect simultaneously.The backflow of condensed fluid is mainly rotated the centrifugal force of generation along the component of heat pipe cavity inner wall face by means of axle, and the liquid working substance that promotes in the heat radiation chamber is back to heat-absorbing chamber along the heat pipe axial wall plane, forms the cyclic process with the continuous discharge of heat.
