Abstract
The utility model discloses a solar energy vacuum heat collecting pipe, which comprises an inner pipe, an outer pipe, and a connector. The connector of the heat collecting pipe is arranged with a connecting thread mutually matched with the socket of a water tank inner liner along the outer surface of the cylindrical pipe. The vacuum heat collecting pipe adopts the structure, the connection mode of the connector and the socket of the water tank inner liner is changed into an insertion mode which is the thread connection, the connection part is firm and reliable, the larger allowed pressure can be borne, and the thermal efficiency and the operation quality are improved.
Description
The utility model relates to a kind of device of solar energy equipment, especially for the glass heat-collecting vacuum tube on the solar water heater.
Solar energy is that human what utilize the earliest also is the cleanest energy.Solar water heater is the Green Product that directly utilizes solar energy, and it has represented the developing direction of human using energy source.The vacuum heat-collecting tubular type water heater of the widely used high-tech content of people can effectively be converted into heat energy to solar energy by vacuum heat collection pipe at present, has higher heat absorption rate and lower rate of heat dissipation.Compare its big, the saving precious metal material of thermal efficiency height, capacity with flat-plate collector, but its allowable pressure is lower.This mainly is because the connected mode between vacuum tube and the water tank causes.The existing glass tube with vacuum of Shi Yonging, profile is the light pipe formula, its interface directly inserts in the rubber seal of inner water tank, relies on the strain of sealing ring to compress the vacuum tube interface, reaches the purpose that connects with sealing.This connected mode is simple in structure, plug-in mounting convenient, but bonding strength is low, and allowable pressure is corresponding also low.The aging elasticity of rubber seal reduces after using a period of time, and switching performance and sealing property all can be affected, in addition leak air, drainage, this is one of major reason that influences the water heater service property (quality).
The purpose of this utility model provides a kind of solar vacuum heat-collecting pipe that improves thermal-collecting tube and inner water tank bonding strength.
The purpose of this utility model is realized by following technical scheme.
A kind of solar vacuum heat-collecting pipe comprises interior pipe, outer tube, interface, and its special improvements are: the interface of described vacuum heat collection pipe is provided with the connecting thread that the birdsmouth with inner water tank is complementary along its cylindrical tube outer surface.
Above-mentioned vacuum heat collection pipe, described interface can be conical butts, and connecting thread is arranged on the outer surface of interface conical tube.
Adopt the vacuum heat collection pipe of said structure, its interface changes plug-in for being threaded with the connected mode of inner water tank (or other parts that catchment) birdsmouth, the threaded portion of interface is born bonding strength, rubber seal only seals, therefore improved the intensity of connecting portion greatly, higher allowable pressure be can bear, thereby the thermal efficiency and the service property (quality) of water heater also just improved.
Below in conjunction with accompanying drawing the utility model is described in detail;
Fig. 1 is the structural representation of solar vacuum heat-collecting pipe.
As seen from the figure, the body 1 of vacuum heat collection pipe is made up of interior pipe 4 and outer tube 5, leaves certain space between two pipes, and moulding is melted with mold hot in the interface position, makes connecting thread 3 on the cylindrical tube outer surface of interface 2.Because the inside and outside tube wall in interface 2 places fuses into one, so the intensity of interface 2 also can improve.The tail end rounding off of inner and outer pipes, the reducing sealing-in, seal the circle blunt, vacuumize between inner and outer pipes.The diameter of interface 2 can be less than the diameter of outer tube 5, also can be identical with the diameter of outer tube 5, need decide on it.
The course of work of vacuum heat collection pipe is as follows: thermal-collecting tube links to each other with water tank, is full of water in the pipe, when the sunlight direct irradiation or by baffle reflection when pipe is gone up, thermal-collecting tube is heat transferred water, and the water back proportion that is heated diminishes uply, and cold water is dirty to be replenished, so circulation, water promptly is heated.The inner tube outer surface coating can improve the assimilation effect of heat, and vacuum can realize extremely low rate of heat dissipation between pipe.
During use, the interface 2 of vacuum tube is added corresponding sealing ring, the birdsmouth that screws in inner water tank is also tightened.Vacuum tube has promptly been realized solid and reliable being connected with water tank like this.Even use or repeatedly dismantle the bonding strength and the sealing property that also can not influence interface for a long time.Because the raising of bonding strength the normal pressure sealing of water heater can be changed into the sealing of elevated pressures, so the efficiency of heating surface can further improve.
As another embodiment of the present utility model, interface also can be processed into conical butt, and threaded portion is provided with along the conical tube outer surface, and this structure can make vacuum tube easier for installation, and sealing property is better than the cylindrical tube interface.
The utility model is except that the heat collecting element as single user's water heater, and the mounting means of its simple and fast, solid and reliable bonding strength are more suitable for as the heat collecting element in the large-scale group type water heater of places such as hotel, natatorium use.
