Abstract
The utility model provides an anti-freezing solar vacuum heat collecting tube and relates to the technical field of a solar water heater. An elastic bar is arranged in a vacuum heat collecting tube and is connected on the inner wall of the vacuum heat collecting tube by a support frame. In the utility model, the elastic bar is arranged in the vacuum heat collecting tube, when the external temperature is over low, the water in the tube is condensed, and the volume is expanded, the elastic bar absorbs and compensates the change of volume of the water in the tube, thereby reducing the pressure on the inner wall of the vacuum heat collecting tube and avoiding frost cracking of the vacuum heat collecting tube. The anti-freezing solar vacuum heat collecting tube has simple structure and convenient implementation, can prevent the damage of the anti-freezing solar vacuum heat collecting tube effectively and can be modified on the existing solar water heater.
Description
Technical field
The utility model relates to technical field of solar water heaters.
Background technology
The freezing situation of vacuum heat collection pipe often takes place in vacuum heat-collecting tubular type solar water heater in the winter time.Its reason is that the water in the vacuum tube condensed after ambient temperature descended, and volumetric expansion is with the vacuum tube bursting by freezing.Because solar water heater all is mounted in roof usually, keeps in repair very inconvenient.And in the winter time, may cause large tracts of land to damage, the maintenance personal is difficult in time satisfy the maintenance requirement of visually-impaired user.
The utility model content
The utility model provides a kind of and has condensed at water at above problem, during volumetric expansion, overcomes the freeze-proofing evacuated solar collector tube of vacuum heat-collecting tracheal rupture by the compensation Volume Changes.
The technical solution of the utility model is: be provided with a flexible rod in vacuum heat collection pipe, flexible rod is connected on the vacuum heat-collecting inside pipe wall by bracing frame.
Described flexible rod is the plastic material hollow rod-shape.
Described flexible rod is that plastic material is solid bar-shaped.
The utility model is provided with a flexible rod in vacuum heat collection pipe, when outdoor temperature is low excessively, when water condenses volumetric expansion in the pipe, manage the Volume Changes of interior water by flexible rod " absorption ", " compensation ", reduce the pressure on the vacuum heat-collecting inside pipe wall, avoid the vacuum heat collection pipe bursting by freezing.The utility model is simple in structure, and it is convenient to implement, and can prevent effectively that vacuum heat collection pipe from damaging.And can on prior solar water heater, reequip.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
1 is vacuum heat collection pipe among the figure, the 2nd, and bracing frame, the 3rd, flexible rod.
The specific embodiment
The utility model is provided with a flexible rod 3 as shown in drawings in vacuum heat collection pipe 1, flexible rod 3 is connected on vacuum heat collection pipe 1 inwall by bracing frame 2.
Flexible rod 3 is the plastic material hollow rod-shape.When being squeezed, can be out of shape, effectively vacuum heat collection pipe 1 be carried out " off-load ".
Flexible rod 3 also is that plastic material is solid bar-shaped.As long as it has the rupture strength of elastic deformation force less than vacuum heat collection pipe.
Claims (3)
1, freeze-proofing evacuated solar collector tube is characterized in that, is provided with a flexible rod in vacuum heat collection pipe, and flexible rod is connected on the vacuum heat-collecting inside pipe wall by bracing frame.
2, freeze-proofing evacuated solar collector tube according to claim 1 is characterized in that, described flexible rod is the plastic material hollow rod-shape.
3, freeze-proofing evacuated solar collector tube according to claim 1 is characterized in that, described flexible rod is that plastic material is solid bar-shaped.
