Abstract
An all-glass straight-through type evacuated collector tube comprises an inner tube (1) and an outer tube (2), wherein, the inner tube (1) adopts an arc-shaped bending structure; a light absorption layer is plated at the excircle of the inner tube (1); the ports of the inner tube (1) and the outer tube (2) are connected in a smooth manner; the part between the inner tube (1) and the outer tube (2) is closed, pumped and vacuumized; ring-shaped grooves (5) are formed at two end parts of the outer tube (2); and a reflective layer (4) is arranged on the inner surface or the outer surface at the bottom of the outer tube (2). The utility model has the advantages of simple structure, stability, high efficiency, and convenient maintenance.
Description
One, technical field
The utility model relates to a kind of solar-energy water heater vacuum thermal-collecting tube, the through-type vacuum heat collection pipe of particularly a kind of full glass.
Two, background technology
Solar water heater all adopts full glass cecum vacuum heat collection pipe at present, sees accompanying drawing 1.This type thermal-collecting tube is because an end seals, and thermal-arrest water can only the interior microcirculation of tube externally carry out heat exchange, causes rate of heat exchange to reduce.In order to overcome the defective of full glass cecum vacuum heat collection pipe, the present through-type vacuum heat collection pipe of announcing of full glass is seen accompanying drawing 2.Because structure, technical scheme are immature, the through-type vacuum heat collection pipe of being announced of full glass, in the time of can not overcoming by solar radiation, inner and outer pipes is because the stress difference that thermal expansion causes, the bombing that causes easily, split pipe, the defective of leaking gas.
Three, summary of the invention
Goal of the invention of the present utility model is to make a kind of through-type vacuum heat collection pipe of full glass that is difficult for bursting.
For achieving the above object, the utility model provides a kind of full glass through-type vacuum heat collection pipe, pipe and outer tube in comprising, and interior pipe arc-shaped bend, cylindrical is coated with light-absorption layer; In pipe and outer tube two-port, slick and sly sealing-in is airtight, bleeds, vacuum; Outer tube bottom inner face or outside are provided with reflector layer; The outer tube both ends are provided with annular groove.
The utlity model has simple in structure, stability and high efficiency, advantage easy to maintenance.

Five, the specific embodiment
The utility model provides a kind of full glass through-type vacuum heat collection pipe, pipe 1 and outer tube 2 in comprising.In pipe 1 bending curvature, cylindrical is coated with light-absorption layer 3, the sealing-in of the enlarging of two-port place and outer tube 2 ports slyness is airtight, bleed, vacuum.Outer tube 2 bottom inner faces or outside are provided with reflector layer 4.
Because in use, interior pipe 1 temperature is higher than outer tube 2, causes between outer tube 2 and the interior pipe 1 axially, the port radial stress is poor.After interior pipe 1 is provided with bending curvature, pipe 1 section axial stress in can absorbing, the possibility of pipe 1 fragmentation in reducing.The optional position of pipe 1 in bending curvature can be arranged on, the two ends and the middle part of pipe 1 also can be provided with one or more bending curvature parts as required in being not limited only to.
At outer tube 2 both ends annular groove 5 is set.Annular groove 5 can buffer portion since expand with heat and contract with cold the outer tube 2 that causes and interior pipe 1 port radially, the axial component stress difference.Also can be used as the installation draw-in groove of vacuum heat collection pipe.
In order to strengthen Heat-collecting effect, outer tube 2 bottom inner faces or outside are provided with reflector layer 4.Since the reflex of reflector layer 4, pipe 1 light-absorption layer 3 comprehensive abundant absorption luminous energy in guaranteeing, the light utilization and the thermal energy conversion efficiency of increase thermal-collecting tube.
This through-type thermal-collecting tube outer tube 2 is designed and sized to the size of existing market standard universal, can substitute original thermal-collecting tube very easily.
Claims (3)
1. the through-type vacuum heat collection pipe of full glass comprises interior pipe (1) and outer tube (2), and interior pipe (1) is connected with outer tube (2) port is slick and sly, it is characterized in that interior pipe (1) is provided with arc-shaped bend.
2. the through-type vacuum heat collection pipe of a kind of full glass as claimed in claim 1 is characterized in that at described outer tube (2) both ends annular groove (5) being set.
3. the through-type vacuum heat collection pipe of a kind of full glass as claimed in claim 1 or 2 is characterized in that at described outer tube (2) bottom inner face or outside reflector layer (4) being set.
