CN2229634Y - Solar energy water heater made of fluorescent lamp tube - Google Patents

Abstract

The utility model relates to a solar energy water heater made of fluorescent lamp tubes, belonging to the field of solar energy absorption and utilization, comprising fluorescent lamp tubes, a plurality of communicating tubes among the fluorescent lamp tubes, thermal insulation materials, an outer shell and transmission plates. In the design of the utility model, a heat absorption layer is arranged between a glass tube and a foam insulating layer, and thus the absorbed heat of the heat absorption layer can be only transferred to the insulating layer and water in the glass tube. The insulating layer has thermal insulation, thus a great amount of heat of the heat absorption layer is transferred to the water in the glass tube in order to rise the temperature of the water, and the water heater has high heat collecting efficiency. The utility model is suitable families, and a plurality of solar energy water heaters made of fluorescent lamp tubes can be connected together for hotels or other public places.

Description

Solar water heater with the fluorescent tube manufacturing

The utility model belongs to solar absorption and utilizes the field.

The purpose of invention is discarded fluorescent tube is used, and it is attractive in appearance to make a kind of pattern, simple in structure, and volume is little, and is in light weight, and cost is low, the solar water heater that collecting efficiency is high, thereby with more extensive more convenient the using of solar energy.

Summary of the invention is as follows: the aluminum lid that the fluorescent tube of collecting is removed two ends.Get through and be used as the thin glass tube that filament is installed below the lid originally, obtain transparent glass tube after cleaning fluorescent powder on the fluorescent tube inwall with the large size test-tube brush, remove the little glass fragment that to stay in the pipe, make the glass tube cleaning totally with tweezers.

The two ends of a plurality of glass tubes are linked together with two plastics communicating pipes as shown in Figure 1 respectively, form an integral body.Two plastics communicating pipe A ends on the whole link to each other with glass tube.And two B ends are used as water inlet and delivery port respectively, glass tube are positioned at the outer surface of same side lacquer blacking on the whole, as heat-sink shell.Thermal insulation layer is made shape as shown in Figure 2 with foamed plastics, with the groove of putting under the side direction as heat-sink shell on the whole on the plastic foamboard.(design of groove size is identical with whole side view, so coincide mutually between integral body and groove).

Load onto shell and transmittance plate at last, finish manufacturing process.

Existing solar water heater have iron sheet flat with two kinds of vacuum type.Compare with these two kinds of water heaters, the utility model does not have water storage tank (can reach tens jin because of pondage that tens glass tubes are linked together, these hot water mixed the adjustable warm water of formation temperature mutually with cold water before passing through shower head, water storage can reach instructions for use fully).Because saved water storage tank and its brandreth of support, the utility model volume is little, and is in light weight, pattern is attractive in appearance, is well suited for being installed under the window or the balcony outside.With the band water storage tank and be installed in the roof water heater and compare, the utility model has adapted to the high-rise residential needs that the city is developed day by day.

The utility model collecting efficiency apparently higher than iron sheet flat (through the test summer water temperature reach 80 ℃, water temperature also can reach 40 ℃ in the winter time, is a kind of annual usable hot water device).The flat shortcoming of iron sheet is that the cross-ventilation heat radiation is big, so collecting efficiency is low owing to the temperature difference between heat-sink shell and the transmittance plate is big.In the utility model design, the heat-sink shell design is between glass tube and foam insulation, heat-sink shell absorption heat can only pass to the water in heat-insulation layer and the glass tube like this, because heat-insulation layer is heat insulation, so heat-sink shell has been passed to the water in the glass tube with a large amount of heat, make water reach high temperature, so this water heater has high collecting efficiency.

The utility model main raw material(s) is a waste daylight lamp tube, and the raw material wide material sources are easy to collect, and the solar water heater that produces is with low cost, because this water heater need not add the installation water storage tank, makes its cost lower.

The utility model is made of glass tube and plastic union pipe, and is corrosion-resistant, Never-rusty, and iron relatively heat collector has longer service life.

Claims (1)

1. A kind of solar water heater made from fluorescent tube comprises fluorescent tube, the communicating pipe between a plurality of fluorescent tubes, insulation material, shell and transmittance plate.It is characterized in that with fluorescent tube as heat absorption original paper in the solar water heater and water storage original paper.
