Abstract
A novel single-tubular heat collector is provided. The external diameter of an internal glass tube of a vacuum heat collecting pipe is no less than 100mm; the length of an external glass tube is no less than 1500mm; a loop of groove is formed on one end surface of the water tank; the vacuum heat collecting pipe is inserted into the groove on the water tank; a silica gel sealing ring is arranged between the water tank and the vacuum heat collecting pipe; and a water inlet pipe, a water outlet pipe and an exhaust pipe are arranged on the water tank. The heat collection system employs only one vacuum heat collecting pipe, so the novel single-tubular heat collector is simply structured, requires low cost and can be conveniently installed.
Description
Technical field
The present invention relates to a kind of solar water heater only with a vacuum heat collection pipe.
Background technology
Existing solar water heater is mainly inserted in water tank by some vacuum heat collection pipes and forms；Water tank is made up of parcel polyurethane insulation coating between stainless steel casing and inner bag；Vacuum heat collection pipe is full glass type double-glass evacuated tube, its general structure includes outer glass pipe, inner glass tube, it it is low-voltage vacuum layer between outer glass pipe and inner glass tube, the outer surface of inner glass tube scribbles heat-sink shell, one end of outer glass pipe and inner glass tube Self-enclosing respectively forms free end, and the other end of outer glass pipe forms opening with the mutual welding of the other end of inner glass tube.The diameter of the outer tube of existing vacuum heat collection pipe is generally 47mm, 58mm or 70mm；Outer bore 70mm, the vacuum heat collection pipe of length 2m is the vacuum heat collection pipe that existing routine is maximum, the major function of existing vacuum heat collection pipe absorbs solar energy exactly, then its interior heat is stored in water tank by thermal convection current, water tank is responsible for storing hot water, it is limited by the size of existing vacuum heat collection pipe, less hot water in vacuum heat collection pipe, can only be stored；Owing to many vacuum heat collection pipes insert in water tank, need on water tank, to offer multiple hole to coordinate vacuum heat collection pipe, reduce the heat-insulating property of water tank, and its required support of collecting system of many vacuum heat collection pipes and water tank composition is also relatively larger, cost is high, installs relatively time-consuming effort.
Summary of the invention
In order to improve existing solar water heater heat insulation effect and reduce cost, the present invention provides a kind of Novel single tube formula heat collector, and this Novel single tube formula heat collector absorbs sunlight and good heat insulating only with a vacuum heat collection pipe, and cost is low, is easily installed.
The technical solution adopted for the present invention to solve the technical problems is: the outer glass pipe of the vacuum heat collection pipe of Novel single tube formula heat collector forms the opening of vacuum heat collection pipe with the mutual welding in one end of inner glass tube, each self sealss form free end to outer glass pipe with the other end of inner glass tube, outer surface at inner glass tube plates absorption film, the external diameter of described inner glass tube is not less than 100mm, the length of described outer glass pipe is not less than 1500mm, end face at water tank is provided with a circle groove, vacuum heat collection pipe inserts in the groove of water tank, silica gel sealing ring it is provided with between water tank and vacuum heat collection pipe, water tank is provided with water inlet pipe, outlet pipe and exhaustor.
Described water inlet pipe is inserted into the bottom of vacuum heat collection pipe after entering water tank.
The optimized dimensions of the external diameter of described interior glass ranges for 150mm to 250mm.
The optimized dimensions of the length of described outer glass ranges for 2000mm to 2500mm.
Water tank is generally adopted by polyurethane insulation coating, polyurethane insulation coating has heat insulation effect more better than general vacuum heat collection pipe, and the hot water in native system is in the water tank on this collecting system top due to smaller its of density, and the relatively low water level of relative temperature is in the vacuum heat collection pipe of bottom, top adopts water tank heat preserving, bottom adopts vacuum heat collection pipe insulation, optimizes the heat-insulating property of native system.The optimized dimensions of the size according to thermal-collecting tube provided by the invention, particularly thermal-collecting tube so that single thermal-collecting tube also is able to absorb the water in solar energy heating collecting system, vacuum heat collection pipe also is able to store more hot water simultaneously；Silica gel sealing ring between vacuum heat collection pipe and water tank plays the purpose preventing water from revealing.
The invention has the beneficial effects as follows, collecting system is only with a vacuum heat collection pipe, simple in construction, and cost is low, and easy for installation.
