Abstract
The utility model discloses a non-water tank type solar water heater which comprises a double-layer vacuum glass tube for heat collection and a metal liner for water storage; the metal liner is sleeved in the double-layer vacuum glass tube; the opening end of the metal liner is provided with an end enclosure; a cold water inlet pipe and a hot water outlet pipe are arranged on the end enclosure; a vacuum layer of the double-layer vacuum glass tube has dual functions of light transmission and heat insulation in order that solar light and heat can only come in but can not come out, thereby greatly improving heat exchange efficiency; the metal liner is a water storage device, thereby improving the capacity for bearing pressure, solving the problems that the double-layer vacuum glass tube is directly used as the water storage device and is easy to crack, prolonging the service life of the double-layer vacuum glass tube and reducing maintenance cost; and no pressure relief device needs to be mounted, thereby reducing the manufacturing cost and improving the service life.
Description
Technical field
The utility model relates to a kind of solar water heater, relates in particular to a kind of solar water heater that does not have water tank.
Background technology
Solar energy is as the environmental protection regenerative resource, and its development and utilization because of complying with the energy and the environmental protection policy of China, comes into one's own day by day, also obtains consumers in general's favor.
At present, in glass tube with vacuum solar water heater industry, bearing operation mainly is heat pipe and two circulating technologies, and water tank and glass tube are independently, make, installation is cumbersome, and the operating cost height, heat exchange efficiency is low.People have developed non-water tank solar water heater according to these shortcomings, this non-water tank solar water heater directly uses glass tube with vacuum as water tank, heat exchange efficiency height like this, make simple, reduced cost, but the glass tube with vacuum bearing capacity is poor, is easy to allow the vacuum glass tracheal rupture, shorten service life greatly, improved the expense of maintenance.
The utility model content
Technical problem to be solved in the utility model provides a kind of bearing capacity height, the water tank free solar water heater that heat exchange efficiency is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: the water tank free solar water heater, comprise the dual-layer vacuum glass pipe that is used for thermal-arrest, also comprise the metal inner tube that is used for water storage, described metal inner tube is set in the described dual-layer vacuum glass pipe, the openend of described metal inner tube is provided with end socket, and described end socket is provided with cold water inlet and hot water outlet pipe.
Owing to adopted technique scheme, the water tank free solar water heater, comprise the dual-layer vacuum glass pipe that is used for thermal-arrest, also comprise the metal inner tube that is used for water storage, described metal inner tube is set in the described dual-layer vacuum glass pipe, the openend of described metal inner tube is provided with end socket, and described end socket is provided with cold water inlet and hot water outlet pipe; The vacuum layer of dual-layer vacuum glass pipe has double action, and not only printing opacity but also heat insulation makes the sunlight heat only import but no export, has improved heat exchange efficiency greatly; Described metal inner tube is a water storage device, improved its bearing capacity, solved the problem that directly bursts easily with the dual-layer vacuum glass pipe as water storage device, prolonged the service life of dual-layer vacuum glass pipe, reduced maintenance cost, and no longer need to install pressure relief device, and reduced cost of manufacture, improved service life.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, the water tank free solar water heater comprises the dual-layer vacuum glass pipe 1 that is used for thermal-arrest, the interlayer of vacuum has double action, and not only printing opacity but also heat insulation makes the sunlight heat only import but no export, under same sunshine, same manufacture craft condition, the efficient heat that absorbs is many.Because as long as the technology of vacuum tube sputter is identical, the absorptivity of heat absorption rete is the same with emissivity; Since vacuum heat-preserving will be good than polyurethane insulation many, so the efficient heat that absorbs is just many.
Also comprise the metal inner tube 2 that is used for water storage, described metal inner tube 2 is set in the described dual-layer vacuum glass pipe 1, and the openend of described metal inner tube 2 is provided with end socket 3, and described end socket 3 is provided with cold water inlet 4 and hot water outlet pipe 5.Described metal inner tube 2 bearing capacity height, solved the problem that directly bursts easily with dual-layer vacuum glass pipe 1 as water storage device, prolonged the service life of dual-layer vacuum glass pipe 1, reduced maintenance cost, and no longer need to install pressure relief device, reduce cost of manufacture, improved service life.
Be provided with location rubber ring 6 between described dual-layer vacuum glass pipe 1 and the described metal inner tube 2.
Described end socket 3 is provided with heat-insulation layer 7, can prevent to reach better heat insulation effect from end socket 3 dissipated heats.
Described metal inner tube 2 we adopt SUS-3042B food-grade corrosion resistant plate to make, and reaches environmental protection requirement.
In order to increase moisture storage capacity, we generally use several the utility model series connection or parallel connection, and hot water is extruded by cold water during use, the water that holds in the body all is able to effective utilization, not needing the water level meter, also do not need to go up cold water again, is automatic water heater.And because hot and cold water pressure is identical, water temperature is regulated sensitive, just can use as long as open valve, and is easy to use, avoided the sometimes hot and sometimes cold phenomenon of water temperature appearance when bathing.
