Abstract
The utility model relates to a solar water heater, namely an internal circulation type solar water heater, which comprises a plurality of heat collecting tubes with upper ends connected with a thermal insulating water tank and a pipeline. The lower ends of the heat collecting tubes are connected with a thermal insulating water tank; and the upper thermal insulating water tank is communicated with the lower thermal insulating water tank through a pipeline. An auxiliary electric heater is positioned in the lower thermal insulating water tank. Because the lower thermal insulating water tank is added and the pipeline for communicating the upper thermal insulating water tank and the lower thermal insulating water tank is arranged, the circulation and the water quality are improved. Dead water in the heat collecting tubes is changed into flowing water, thereby having good freezing resistance; meanwhile, because the auxiliary electric heater is placed in the lower thermal insulating water tank; heated water quickly enters the heat collecting tubes, so that the heat collecting tubes are inadvisable to frost damage and have more reliable use.
Description
Technical field
The utility model relates to a kind of solar water heater, i.e. the inner circulation type solar water heater.
Background technology
In the prior art, solar water heater commonly used is made up of vacuum heat collection pipe, attemperater and support.Utilize the vacuum tube thermal-arrest, realize to greatest extent photo-thermal conversion utilizing hot water light, the physical phenomenon that cold water is heavy is sent to hot water in the attemperater through microcirculation, by dedicated line to the user.By control valve, controller etc. are delivered to solar energy to reach automation control to control system running water.The auxiliary electrical heating is placed in the attemperater, is equipped with the moon, rain, the use of snow sky.Its shortcoming be the thermal-collecting tube bottom for shutting structure, it is not smooth to circulate, freezing easily in cold winter in the north, influence is used.
The utility model content
The purpose of this utility model is the inner circulation type solar water heater that a kind of better adaptability is provided at above-mentioned deficiency.
Technical solution of the present utility model is: the inner circulation type solar water heater comprises thermal-collecting tube and the inlet and outlet pipe that many upper ends are communicated with last attemperater.The thermal-collecting tube lower end also connects an attemperater, also is communicated with pipeline between the upper and lower attemperater.The auxiliary electrical heating is placed in down in the attemperater.
The utility model has the advantages that: 1, increased time attemperater and upper and lower attemperater connecting pipeline is set, improved circulation, improved water quality (become vexed solarization and shine into circulation, water is not perishable).2, stagnant water becomes running water in the thermal-collecting tube, good frost resistance, and electrical auxiliary heater is placed in down in the attemperater simultaneously, and the water of heating enters in the thermal-collecting tube fast, makes thermal-collecting tube unsuitable freezing, uses more reliable.3, the utility model is fit to large-scale integrated heat supply more.Adopt upper and lower intercommunication attemperater and thermal-collecting tube interworking architecture up and down, hot and cold water can be separated, take their own roads, improve integrated service efficiency.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model structure diagram.
The specific embodiment
Referring to accompanying drawing, the inner circulation type solar water heater comprises thermal-collecting tube 2 and the inlet and outlet pipe 3 that many upper ends are communicated with last attemperater 1.Thermal-collecting tube 2 lower ends also connect a following attemperater 4, and promptly thermal-collecting tube 2 is connected with upper and lower attemperater 1,4 and communicates.And arranged on left and right sides respectively is communicated with water lines 5,6 between the upper and lower attemperater 1,4.Electrical auxiliary heater 7 is installed in down in the attemperater 4, can heat to the cold water in the case, avoids thermal-collecting tube 2 to freeze quick-fried bursting by freezing.Following attemperater 4 is provided with Clean-discharging valve 8.This solar water heater material and the same prior art of other structure member.Last attemperater 1 inner cold water enters into down attemperater 4 by the water lines 5,6 of both sides, the hot water or cold water can separate, and ejects hot water to last attemperater 1 through thermal-collecting tube 2, forms the microcirculation loop, improve hot water or cold water's convection velocity, overcome the shortcoming of circulation in original thermal-collecting tube single tube.
Claims (2)
1. inner circulation type solar water heater, comprise thermal-collecting tube (2) and inlet and outlet pipe (3) that many upper ends are communicated with last attemperater (1), it is characterized in that thermal-collecting tube (2) lower end also connects a following attemperater (4), is communicated with water lines (5,6) between the upper and lower attemperater (1,4).
2. according to the described inner circulation type solar water heater of claim 1, it is characterized in that electrical auxiliary heater (7) is placed in down attemperater (4) lining.
