Abstract
The invention provides a thermal insulation pipe, which comprises a first pipe body and a heating layer, wherein a medium flow passage is arranged in the first pipe body; and the heating layer is arranged on the inner wall of the first pipe body. Through arrangement of the heating layer of the thermal insulation pipe, the heat dissipated by a medium can be replenished, so that the temperature of the medium fluctuates in a smaller range, and higher temperature difference is prevented from occurring between the medium at an inlet and a medium at an outlet.
Description
Technical field
The present invention relates to the tubing technical field, in particular to a kind of thermal insulation pipe.
Background technique
In the prior art, thermal insulation pipe in the solar energy heating device comprises body and the heat-preservation cotton or the heating tape that are wrapped on the outer surface of tube body, by the thermal insulation layer that heat-preservation cotton or heating tape form the medium in the body and external environment condition are isolated, reduce the interior medium of body reaches insulation with extraneous heat exchange amount purpose.But this set can only be incubated the medium in the body to a certain extent, and heat insulation effect is poor, and the residing environment of body is had certain requirement, and is also inapplicable under the environment of low temperature.
Summary of the invention
The present invention aims to provide a kind of thermal insulation pipe, to solve the poor problem of heat insulation effect of thermal insulation pipe in the prior art.
To achieve these goals, the invention provides a kind of thermal insulation pipe, comprising: the first body has the medium flow channels in the first body; Zone of heating, zone of heating are arranged on the inwall of the first body.
Further, zone of heating is electric silk screen.
Further, the first body is metal tube.
Further, the first body is iron pipe.
Further, also comprise the second body, the second body is set in outside the first body, and is filled with thermal-protective coating between the first body and the second body.
Further, the material of the second body is polyethylene.
Further, the material of thermal-protective coating is polyurethane.
In technological scheme of the present invention, be provided with zone of heating on the inwall of the first body, arranging of zone of heating can replenish the heat that medium loses, the temperature of medium is fluctuateed in less scope, avoid the larger temperature difference occurring between the medium in the medium of inlet of thermal insulation pipe and outlet port.
Description of drawings
The Figure of description that consists of the application's a part is used to provide a further understanding of the present invention, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 shows the cross-sectional schematic according to the embodiment of thermal insulation pipe of the present invention; And
Fig. 2 shows the enlarged diagram at A place of the thermal insulation pipe of Fig. 1.
Embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
In conjunction with referring to Fig. 1 to Fig. 2, as can be seen from the figure, the thermal insulation pipe of present embodiment comprises the first body 10 and zone of heating 40, wherein, has the medium flow channels in the first body 10, and zone of heating 40 is arranged on the inwall of the first body 10.The thermal insulation pipe of present embodiment, heat the medium that in the medium flow channels, circulates by the zone of heating 40 on the inwall that is arranged on the first body 10, the temperature of guaranteeing medium fluctuates in less scope, avoids the larger temperature difference occurring between the medium in the medium of inlet of thermal insulation pipe and outlet port.
The thermal insulation pipe of present embodiment also comprises the second body 20 and thermal-protective coating 30.Wherein, the second body 20 is set in outside the first body 10, and thermal-protective coating 30 is arranged between the first body 10 and the second body 20.The heat that thermal-protective coating 30 can completely cut off the medium in the first body 10 effectively scatters and disappears to the external world, plays the effect of insulation.
A kind of preferred embodiment in, the first body 10 is metal tube, the use of metal tube can make thermal insulation pipe have certain structural strength, and the good sealing effect of metal tube, be difficult for to produce the phenomenons such as medium seepage.Further preferably, the first body 10 is iron pipe.
As outermost the second body 20, its material is preferably polyethylene pipe, adopts the second body 20 of polythene material can play good uvioresistant and aging-resistant effect, prolongs the service life of thermal insulation pipe.
The thermal-protective coating 30 preferred polyurethane that adopt are as thermal insulating material, and polyurethane also has bonding and the sealing texts, environmental protection and energy saving and easy to use except having good heat insulation effect.
Zone of heating 40 is preferably electric silk screen, when medium flows in the first pipe, can heat medium electric heating wire, and the medium dispersed heat is replenished, and the temperature of medium is fluctuateed in less scope.The thermal insulation pipe of present embodiment, the employed material of each layer all carry out work in temperature in-40 ° to 180 ° the scope interval, guarantee that thermal insulation pipe can normally use at low-temperature region or high-temperature area, have widened the using scope of thermal insulation pipe.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
