Abstract
The utility model relates to a sole-head vacuum heat-insulating metal heat-collecting pipe, comprising a glass inner pipe, a glass outer pipe and a bracket. A sealed vacuum layer is formed between the inner pipe and the outer pipe, one end of the glass inner pipe is open while the other end is closed. A metal pipe whose one end is open while the other end is closed is arranged into the glass inner pipe. A piece of film is plated on the outer wall of the metal pipe and the gap between the metal pipe and the glass pipe is sealed by the sealing materials. The utility model has high heat-exchanging efficiency, with stronger resist compression, pressure-proof and anti-distortion capability and t save usage.
Description
(1) technical field: the utility model relates to the employed a kind of collector metal pipe of solar water heater, is specifically related to the logical vacuum heat-insulating pipe collector metal pipe of a kind of single head.
(2) background technology: by retrieval, Chinese patent ZL99215356.5 discloses a kind of metal-glass vacuum tube, and it mainly is made of glass inner tube, outer tube and metal tube.Be coated with selective absorbing film on the glass inner tube outer surface, form vacuum state between glass inner tube and the glass outer tube interlayer.Metal tube places glass inner tube, and glass inner and outer pipe and metal tube adopt the design of single-ended opening.On the heat-sink shell of solar radiation in glass inner tube, luminous energy becomes heat energy, and heat passes through water, metal pipe-wall between glass inner tube and the metal tube again by glass inner tube, is delivered at last in the water in the metal tube, makes the water heating.Like this, because the heat that absorbs by multiple medium transmission, causes the thermal efficiency to reduce.Secondly, because selective absorbing film is to be coated on the inner layer glass,,, cause the whole system paralysis if improper use might make the vacuum tube explosion so inner layer glass can reach very high temperature.
The purpose of this utility model proposes a kind of thermal efficiency height exactly, and single head safe in utilization leads to vacuum insulation collector metal pipe.
(3) summary of the invention: the utlity model has glass inner tube, glass outer tube, support, form the vacuum layer of sealing between the inner and outer pipes, metal tube is housed in glass inner tube, described glass inner tube and metal tube are single-ended opening, with encapsulant sealing, its improvements are that the outer wall at described metal tube is coated with the heat absorption rete between glass tube and the metal tube.
Owing to adopt technique scheme, to compare with prior art education, the heat that the utility model absorbs directly by metal tube transmission feedwater, has improved the thermal efficiency; Simultaneously, because the heat-resisting resistance to pressure of metal is strong, " thermal explosion ", " cold quick-fried " phenomenon can not take place, safe to use.
(4) description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a metal tube outer wall plated film layer broken section enlarged diagram among Fig. 1.
(5) specific embodiment:
As shown in fig. 1, the glass inner tube 1 and the glass inner tube 2 of different inner diameters are nested together, the centre is provided with support 3, vacuumize the vacuum layer 4 that forms sealing between the inner and outer pipes, and interior pipe one end opening one end sealing, between interior pipe, pack into the metal tube 5 of an end opening, end sealing, metal tube and glass tube seal as silica gel with encapsulant 6 at openend; As shown in Figure 2, above-mentioned inner wall of metal tube polishing, outer wall is coated with basal layer 7, the black layer 8 heat absorption rete that is constituted respectively.
Claims (1)
1. single head leads to vacuum insulation collector metal pipe, have glass inner tube [1], glass outer tube [2], support [3], form between the inner and outer pipes sealing vacuum layer [4], described glass inner tube in metal tube [5] is housed, glass inner tube and metal tube are single-ended opening, it is characterized in that: described metal tube outer wall is coated with the heat absorption rete.
