Abstract

A heat collecting tube for a solar water heater is mainly composed of connecting joints, seal gaskets, inner and outer pressure covers, a pressure beating metal heat-absorbing tube, heat-absorbing fins and an external glass tube; the heat-absorbing fins are fixed on the pressure beating metal heat-absorbing tube which is arranged in the external glass tube; both ends of the external glass tube are sealed by inner pressure covers, seal gaskets and outer pressure covers; both ends of the pressure beating metal heat-absorbing tube are threaded through the inner pressure covers, the seal gaskets and the outer pressure covers and connected with the connecting joints; one end of the connecting joint is connected with a tank connecting pipe, while the other end is connected with a hot water storage tank. The heat collecting tube has simple structure, easy manufacturing and high thermal efficiency; the heat collecting tubes can be densely arranged so as to improve the mounting space utilization rate; as the heat collecting tube can bear pressure, the water inlet control part commonly used on a glass vacuum tube heat collector can be eliminated, and the water inlet pipe can be connected directly on the tank connecting pipe at the lower part; therefore, the heat collecting tube is ideal for cluster users.

Three, summary of the invention

The technical problems to be solved in the utility model is: design a kind of thermal-collecting tube of novel solar water heater, be used to make efficient pressure-bearing solar water heater, to overcome the shortcoming that prior art exists.

The technical scheme that solution the utility model technical problem is taked is: it is made up of connector 1, black box, pressure-bearing heat absorption assembly, outer glass pipe 13, pressure-bearing heat absorption assembly comprises pressure-bearing metal endothermic tube 14 and heat absorption fin 11 fixed thereon, and pressure-bearing heat absorption assembly is located in the outer glass pipe 13; Black box comprises internal gland 10, sealing gasket 9, outer gland 8, and outer glass pipe 13 two ends are sealed by black box, and pressure-bearing metal endothermic tube 14 two ends are passed black box and are connected with connector 1, and connector 1 one ends connect header tube, and the other end connects heat storage water tank; At one end on the internal gland 10 of black box a vacuum-pumping tube 7 is arranged, sealing gasket 9, outer gland 8 are provided with corresponding aperture, vacuum-pumping tube 7 passes sealing gasket 9 and outer gland 8 glass tube 13 outsides that expose outside, and communicates with the external world, with outer glass pipe 13 interior sealed after being vacuumized.

Connector 1 can adopt following connected mode with being connected of pressure-bearing metal endothermic tube 14: the sleeve pipe 5 of respectively establishing silk outside the band on the internal gland 10 at two ends, pressure-bearing metal endothermic tube 14 two ends penetrate the sleeve pipe 5 of internal gland 10 respectively, collar extension is concordant with sleeve pipe 5, and weld together with sleeve pipe 5, then sealing gasket 9, outer gland 8 are enclosed within sleeve pipe 5 outsides, internal gland 10, sealing gasket 9, outer gland 8 are pressed to outer glass pipe 13 ends with a clamping nut 6; Be provided with an outside edge 3 in connector 1 the inner, be provided with sealing gasket 3 between pressure-bearing metal endothermic tube 14 and the connector 1, have a cap 2 that connector 1, sealing gasket 3 are pressed on pressure-bearing metal endothermic tube 14 ends.

Good effect of the present utility model is: simplified manufacturing process, thermal-collecting tube thermal efficiency height; Thermal-collecting tube can dense arrangement, can improve the installing space utilization rate; Connect thermal-collecting tube by connector, easy to maintenance; Because thermal-collecting tube can pressure-bearing, so can save water inlet control section commonly used on the glass-vacuum tube heat collector, directly water inlet pipe is connected on the header tube of bottom, be fit to very much cluster user and install and use.

Four, description of drawings

Accompanying drawing 1 is a structural representation of the present utility model; Accompanying drawing 2 is used for single user mode figure with house type for the utility model; Accompanying drawing 3 is used for the user mode figure of cluster user type for the utility model.

Five, the specific embodiment

The utility model as shown in Figure 1, it mainly contains connector 1, sealing gasket 9, internal gland 10, outer gland 8, pressure-bearing metal endothermic tube 14, heat absorption fin 11, outer glass pipe 13 compositions, be coated with heat absorbing coating on pressure-bearing metal endothermic tube 14 and the heat absorption fin 11, heat absorption fin 11 width are slightly smaller than the diameter of outer glass pipe 13, central longitudinal to have one with the identical deep-slotted chip breaker of pressure-bearing metal endothermic tube 14 radians, deep-slotted chip breaker is encased pressure-bearing metal endothermic tube 14, be fixed on the pressure-bearing metal endothermic tube 14 with arc card 12 fin 11 that will absorb heat; Pressure-bearing metal endothermic tube 14 can adopt copper or materials such as aluminium or stainless steel to make, and is located in the outer glass pipe 13, and outer glass pipe 13 two ends are by being sealed by internal gland 10, sealing gasket 9, outer gland 8 successively; The sleeve pipe 5 that silk outside one band is respectively arranged on the internal gland 10 at two ends, pressure-bearing metal endothermic tube 14 two ends penetrate the sleeve pipe 5 of internal gland 10 respectively, collar extension is concordant with sleeve pipe 5, and weld together with sleeve pipe 5, then sealing gasket 9, outer gland 8 are enclosed within sleeve pipe 5 outsides, internal gland 10, sealing gasket 9, outer gland 8 are pressed to outer glass pipe 13 ends with a clamping nut 6; A vacuum-pumping tube 7 is arranged on the internal gland 10 at one end, on sealing gasket 9, outer gland 8, be provided with corresponding aperture, vacuum-pumping tube 7 passes sealing gasket 9 and outer gland 8 glass tube 13 outsides that expose outside when mounted, and communicates with the external world, with outer glass pipe 13 interior sealed after being vacuumized; Be provided with an outside edge 3 in connector 1 the inner, between pressure-bearing metal endothermic tube 14 and connector 1, be provided with sealing gasket 4, the edge 3 of connector 1 is pressed on the sealing gasket 4, has a cap 2 that connector 1, sealing gasket 3 are pressed on pressure-bearing metal endothermic tube 14 ends; Connector 1 one ends are welded on the header tube, and the other end is welded on the heat storage water tank.
