Abstract
The invention relates to a heat transfer structure of a vacuum heat-insulated pipe. The vacuum heat-insulated pipe is formed by a double-layer vacuum heat-insulated pipe (1) and a thin-wall connecting end socket (2) through welding and the surface of the double-layer vacuum heat-insulated pipe (1) is provided with exhaust holes (3). According to the vacuum heat-insulated pipe, the air in an interlayer is exhausted according to the principle that the vacuum state is free of heat conduction and accordingly the heat loss in the inner chamber can slow down, the structure is simple, the operation is convenient, and the economic value is high.
Description
Technical field
The invention belongs to heating power transmission field, particularly a kind of heating power transmission structure of vacuum heat-insulating pipe.
Background technique
Current heat-insulated pipe or heat transport tube are generally all used the additional heat insulation layer structure of metal tube, and the thermal insulation layer time has been grown easy to be aging, and thermal insulation property is poor, and thermal loss is large, and efficiency of transmission is low.
Summary of the invention
The present invention is in order to address the aforementioned drawbacks, and by a kind of vacuum heat-insulating pipe designing without heat conducting principle under vacuum state, its structure is as follows:
A vacuum heat-insulating pipe, is connected end socket by double-layer vacuum heat-insulated pipe with thin-walled and is welded to form, and described double-layer vacuum heat-insulated pipe surface is provided with bleeder hole.
Described double-layer vacuum heat-insulated pipe comprises inner chamber and interlayer, and described interlayer is vacuum state, and its internal pressure value is 0.0004Pa, the bleeder hole place sealant sealing on described double-layer vacuum heat-insulated pipe surface.
Described double-layer vacuum heat-insulated pipe is connected end socket weld cover with thin-walled have adiabatic short circuit.
The present invention crosses under vacuum state without heat conducting principle, and the air in interlayer is extracted out, guarantee that heating power in inner chamber runs off to slow down, and also simple in structure, easy to operate, there is very high economic value.
