Description

Vacuum tube type separated type solar water heater

Technical field

The present invention relates to solar water heater, specifically refer to a kind of vacuum tube type separated type solar water heater.

Background technology

Solar water heater just more and more is subjected to liking of people as a kind of clean pollution-free green environmental protecting device.At present, popular solar water heater mostly is desk-top or pressure wall-mounted on the market.Desk-top main composition form is that water tank is associated in vacuum tube; Though pressure wall-mounted formation water tank is associated in the metal tube by a sealing separately but between the vacuum tube of heat collector and the water tank of heat collector.Desk-top operation principle is: vacuum glass is accepted the irradiation of sunlight, the interior water of pipe is heated heats up and buoyance lift, and the water circulation heat-shift with in the attemperater reaches the intensification of whole water.Exist following defective from structure and this solar water heater of heat exchange pattern:

One, glass tube with vacuum and attemperater are integrated, shared space is very big, the live load of water inlet back water heater is very big, significant limitation is arranged laying the place like this, thereby form and often to have only attic resident family just can install and use solar water heater, all the other users think that dress all can't install or use.

Two, because the limitation of the daylighting of desk-top solar water heater, the limitation of the big installation of volume, thereby the installation that causes solar water heater has often influenced the attractive in appearance and integrated of urban architecture, meanwhile, the social concern of initiation such as the safety brought of non-top layer user's installation, percolating water is led and has been made local administration departments and departments of government to the restriction of solar water heater.

Three, the heat exchange of water is the exchange of carrying out in single body pipe naturally in the glass tube with vacuum, and under the not high situation of temperature, the speed that this heat exchange is transmitted is very slow, and heat exchanger effectiveness is very low.

Four, because water tank is associated in vacuum tube, and water tank is above vacuum tube, thus the water in the vacuum tube be forever can't reflow tank for use.And the water in the vacuum tube be forever do not change thereby its scaling serious, its water quality also in time passing constantly degenerates.

Five, solar water heater is placed on outdoor, and the heat dissipation capacity of water tank is very big, severe winter the low temperature low light according under (as evening), solar water heater is very easily icing with indoor inlet and outlet pipe, bursting by freezing.

Six, water heater can't be controlled the water level of water tank in the electric heating process, and the power consumption in the electric heating process is big like this, and its waste is also very surprising, and programming rate is very slow.

The operation principle of pressure wall-mounted solar water heater is: glass tube with vacuum is accepted the irradiation of sunlight, metal tube in the radiant energy heating, vacuum pipe that produces, heat-conducting medium in the metal tube is heated up or vaporization, thereby buoyance lift or forced circulation are to water tank, in water tank, carry out secondary heat exchange transmission feedwater, sinking or forced circulation are returned vacuum tube and are heated so continuous reciprocation cycle, the water in the heating water tank again after the medium cooling.Exist a series of problems from structure and heat exchange pattern and this solar water heater of life-span:

One, vacuum tube is worked under high temperature, long-time, the empty state that shines, and it is very easily rotten that film is crossed in the heat absorption in its pipe intraformational bed, thereby lose its heat absorption function.Therefore its practice result proof service life can not be above 2 years.

Two, the manufacturing cost height, retail price is also very high naturally.

Three, it needs secondary heat exchange, so its thermal efficiency is not high.

Four, in the electric heating process, can't control the water level in the water tank, can only carry out the heating of whole bucket water all the time, big its waste of energy of the consumption of electric energy is also very surprising like this, and programming rate is equally very slow.

Five, owing to need the high pressure bearing operation in the recycle metal pipeline, and also high pressure pressure-bearing in the water tank, so security is low, and once has its maintenance difficulty of fault big, strongly professional and cost is also very high.Etc..
