Abstract
The utility model relates to a built-in thermotube all-glass evacuated solar collector tube. Three layers of glass tube are sleeved with each other, and one end of the three layers of the glass tube is respectively sealed, and the other end of the three layers of the glass tube is connected with each other in a sealing way; the inner layer of glass tube is shorter; working medium is arranged between the middle layer of glass tube and the inner layer of glass tube, and is vacuumized, so as to form a built-in glass thermotube inside the tube. When the built-in thermotube all-glass evacuated solar collector tube is used a solar water heater, the quantity of the invalid water yield inside the built-in thermotube all-glass evacuated solar collector tube is small; in addition, the inner tube isin a thermotube structure, and the condensation end consists of a thin glass tube, so that the utility model has the advantages of fast thermal starting, high condensation end temperature, fast thermal heat exchange speed and the like.
Description
Technical field
The utility model relates in a kind of complete glass vacuum sun thermal-collecting tube (hereinafter to be referred as thermal-collecting tube), the especially thermal-collecting tube and has adopted hot pipe technique, and the heat-collecting temperature of thermal-collecting tube and collecting efficiency thereof are improved.
Background technology
At present, known thermal-collecting tube is an end opening that is overlapping, the double-deck interior outer glass pipe of other end sealing, the mutual sealing-in of its openend, effective Metal pipe strap of other end inner layer glass and outer layer glass tube tighten up, the inner layer glass tube outer wall is coated with coating for selective absorption, and the interlayer between the internal and external layers of glass pipe vacuumizes.There is following shortcoming in this thermal-collecting tube: when thermal-collecting tube uses, owing in the pipe a large amount of water is arranged, be unfavorable for the exchange of heat in the solar water heater, cause and heat up slowly, and the hot water in the pipe can not be effectively used.
Summary of the invention
Invalid ponding is many in the pipe when using in solar water heater in order to overcome present thermal-collecting tube, slow shortcoming heats up.The utility model provides has only a small amount of ponding, the built-in heat pipe type full-glass vacuum solar collector pipe of quick heating in a kind of pipe.The solar water heater who is made up of this kind thermal-collecting tube has programming rate fast, gets the high advantage of heat.
The technical scheme that its technical problem that solves the utility model adopts is: the structure of built-in heat pipe type full-glass vacuum solar collector pipe is that the triplex glass pipe is overlapping mutually, the sealing of closing up separately of the mutually same end of triplex glass pipe, the mutual sealing-in of other end triplex glass pipe.The self sealss end of intermediate layer glass tube tightens up with Metal pipe strap and outer layer glass tube, and the interlayer between intermediate layer glass tube and the outer layer glass tube vacuumizes.Inner layer glass tube is shorter, and adds working medium between the glass tube interlayer of intermediate layer and vacuumize built-in glass heat pipe in the formation pipe.Intermediate layer glass tube outer wall is coated with coating for selective absorption, absorbs solar energy heating working medium.Self sealss end in the inner layer glass tube has the thin glass tube of a plurality of external port sealings, forms a plurality of condensation ends of heat pipe, is convenient to heat exchange.
The beneficial effects of the utility model are: when built-in heat pipe type full-glass vacuum solar collector pipe uses in the solar water heater, invalid ponding is few in the pipe, and interior pipe is a heat pipe structure, advantages such as condensation end is made up of a plurality of thin glass tubes, and therefore built-in heat pipe type full-glass vacuum solar collector pipe has that thermal starting is fast, condensation end temperature height, heat exchange are rapid.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the sectional structural map of built-in heat pipe type full-glass vacuum solar collector pipe embodiment.
1. outer layer glass tubes among the figure, 2. intermediate layer glass tube, 3. inner layer glass tube, 4. thin glass tube, 5. Metal pipe strap, 6. working medium, 7. coating for selective absorption, the 8. mouth of pipe.
The specific embodiment
Among the figure, the sealing of closing up separately of outer layer glass tube (1), intermediate layer glass tube (2) and the mutually same end of inner layer glass tube (3), the other end of triplex glass pipe seals mutually, forms the mouth of pipe (8).The outer wall of intermediate layer glass tube (2) is coated with coating for selective absorption (7), has Metal pipe strap (5) and outer layer glass tube (1) to tighten up at its self sealss end.Inner layer glass tube (3) is shorter, and the self sealss end in its pipe has the thin glass tube (4) of at least one external port sealing.
Interlayer between outer layer glass tube (1) and the intermediate layer glass tube (2), interlayer is vacuum layer between intermediate layer glass tube (2) and the inner layer glass tube (3), in the vacuum interlayer between intermediate layer glass tube (2) and inner layer glass tube (3) working medium (6) is housed.
Claims (3)
1, a kind of built-in heat pipe type full-glass vacuum solar collector pipe, be that the triplex glass pipe is overlapping mutually, the sealing of closing up separately of outer layer glass tube, intermediate layer glass tube and the mutually same end of inner layer glass tube, the other end of triplex glass pipe seals mutually, it is characterized in that interlayer between outer layer glass tube and the intermediate layer glass tube, interlayer is vacuum layer between intermediate layer glass tube and the inner layer glass tube.
2, built-in heat pipe type full-glass vacuum solar collector pipe according to claim 1 is characterized in that in the vacuum interlayer between intermediate layer glass tube and inner layer glass tube working medium being housed.
3, built-in heat pipe type full-glass vacuum solar collector pipe according to claim 1 is characterized in that inner layer glass tube is shorter, and the self sealss end in its pipe has the thin glass tube of at least one external port sealing.
