Abstract
The utility model discloses a solar water heater with a strengthened kovar heat collecting pipe. The solar water heater is composed of a heat insulation water box, a support and a spherical surface strengthened kovar heat collecting pipe, and the solar water heater is characterized in that the spherical surface strengthened kovar heat collecting pipe is formed by that a pipe plate absorber is nested in a cover glass pipe, and the cover glass pipe turns up inward on a connecting port so as to form a sealing-in end surface with a through hole; a kovar ring piece the external diameter of which the outer diameter is 40%-90% of that of the cover glass pipe, the shape is identical with that of the sealing-in end surface, and the middle is provided with a through hole is overlaid on the outer side of the sealing-in end surface with the through hole; an additional glass ring piece the middle of which is provided with the through hole is overlaid on the kovar ring piece, and the inner diameter of the additional glass ring piece is greater than that of the kovar ring piece; the outer diameter of the additional glass ring piece is greater than that of the kovar ring piece; the additional glass ring piece and the kovar ring piece which are mutually overlaid and the sealing-in end surface of the cover glass pipe are in sealing connection by pressure welding through utilizing a mould, and the through hole of the kovar ring piece is in sealing connection with the pipe plate absorbers.
Description
Technical field
The utility model relates to reinforcement can cut down heat-collecting tube solar water heater.
Background technology
The vacuum heat collection element that has many solar water heaters to use all relates to being tightly connected of metal and glass, and existing a kind of sealing-in metal absorber vacuum heat collection element that cuts down adopts joint welding to connect, and its welding portion also has improved space.
Summary of the invention
The purpose of this utility model is to provide reinforcement can cut down heat-collecting tube solar water heater.
The utility model solves technical scheme that its technical problem is taked: can cut down thermal-collecting tube with adiabatic water tank, support and reinforcement, form a reinforcement and can cut down heat-collecting tube solar water heater.Reinforcement can be cut down thermal-collecting tube and be nested with at a cover glass tube and arrange that a tube plate absorber makes.Cover glass tube is located the sealing-in end face that flange inwards forms a band through hole in the connectivity port, sealing-in end face outside stack a slice external diameter of band through hole is cover glass tube external diameter 40% to 90%, shape and the sealing-in end face matches, the centre has through hole cut down circular ring plate.Can cut down the additional glass circular ring plate that has through hole above the circular ring plate in the middle of stack a slice, the internal diameter of additional glass circular ring plate is greater than the internal diameter that can cut down circular ring plate; The external diameter of additional glass circular ring plate is greater than the external diameter that can cut down circular ring plate.The additional glass circular ring plate of described mutual superposition, the sealing-in end face that can cut down circular ring plate and cover glass tube are tightly connected with the mould pressure welding.Through hole and the tube plate absorber that can cut down circular ring plate are tightly connected.
Can also make the sealing-in end face of cover glass tube be the sphere curved surface of outwards heaving.
The beneficial effects of the utility model: by can cutting down the connecting portion two sides pressure welding glass component of connector, for improving the bonding strength that can cut down connector and glass, strengthening its sealing property a new approach is provided.Adopt and strengthen cutting down the solar water heater that thermal-collecting tube is made, the vacuum of its thermal-collecting tube keeps operating mode better.Can cut down and bring the metal heat pipe, can make pressure-bearing water heater.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that a reinforcement can be cut down the heat-collecting tube solar water heater structural representation.
1. adiabatic water tanks among the figure; 2. support; 3. strengthen to cut down thermal-collecting tube; 4. cover glass tube; 5. tube plate absorber; 6. sealing-in end face; 7. can cut down circular ring plate; 8. additional glass circular ring plate.
The specific embodiment
Fig. 1 provides first embodiment of the present utility model.
Among Fig. 1, can cut down thermal-collecting tube 3 with adiabatic water tank 1, support 2 and reinforcement, form a reinforcement and can cut down heat-collecting tube solar water heater.Reinforcement can be cut down thermal-collecting tube 3 and be nested with at a cover glass tube 4 and arrange that a tube plate absorber 5 makes.Cover glass tube 1 is located the sealing-in end face 6 that flange inwards forms a band through hole in the connectivity port, sealing-in end face 6 outsides stack a slice external diameter is cover glass tube 1 external diameter 80%, shape and sealing-in end face 6 matches, the centre has through hole cut down circular ring plate 7.Can cut down the additional glass circular ring plate 8 that has through hole above the circular ring plate 7 in the middle of stack a slice.The additional glass circular ring plate 8 of mutual superposition, the sealing-in end face 6 usefulness mould pressure weldings that can cut down circular ring plate 7 and cover glass tube 1 are tightly connected.Through hole and the tube plate absorber 5 that can cut down circular ring plate 7 are tightly connected.
The thermal-collecting tube of solar water heater is settled towards the south orientation sun usually, and Fig. 1 horizontal setting belongs to special case.
Claims (2)
1. strengthen to cut down heat-collecting tube solar water heater, strengthening cutting down thermal-collecting tube by adiabatic water tank, support and sphere forms, it is characterized in that: sphere is strengthened cutting down thermal-collecting tube and is nested with at a cover glass tube and arranges that a tube plate absorber makes, cover glass tube is located the sealing-in end face that flange inwards forms a band through hole in the connectivity port, sealing-in end face outside stack a slice external diameter of band through hole is cover glass tube external diameter 40% to 90%, shape and the sealing-in end face matches, the centre has through hole cut down circular ring plate; Can cut down the additional glass circular ring plate that has through hole above the circular ring plate in the middle of stack a slice, the internal diameter of additional glass circular ring plate is greater than the internal diameter that can cut down circular ring plate; The external diameter of additional glass circular ring plate is greater than the external diameter that can cut down circular ring plate; The additional glass circular ring plate of described mutual superposition, the sealing-in end face that can cut down circular ring plate and cover glass tube are tightly connected with the mould pressure welding; Through hole and the tube plate absorber that can cut down circular ring plate are tightly connected.
