Abstract

The utility model relates to a solar energy heat utilization technical field, in particular to a bearing-typed solar energy water heater technology, comprising a water storage tank and a heat collector; the heat collector essentially consists of a heat exchange tank and a full-glass vacuum heat collecting pipe; the water storage tank is connected with the heat exchange tank by a cold water pipe and a hot water pipe; the full-glass vacuum heat collecting pipe is internally provided with a U-shaped pressure resistance pipe; adjacent U-shaped pressure resistance pipes are mutually communicated in the heat exchange tank; the U-shaped pressure resistance pipes arranged at two ends are respectively communicated with a cold water pipe and a hot water pipe; the utility model is convenient for manufacture, reduces the connection with the cold water pipe and the hot water pipe, and reduces the leakage phenomenon; meanwhile, as the vacuum heat collecting pipe is communicated with the heat exchange tank, the temperature of mediums in the vacuum heat collecting pipe and the heat exchange tank is increased when the sun shines; as the U-shaped pipe is arranged in the vacuum heat collecting pipe, the heat of the mediums is transmitted to the water in the U-shaped pipe in the vacuum heat collecting pipe; the heated water in the U-shaped pipe heats the water in the bearing water storage tank by the circulation of a water pump, increases the heat transmission efficiency and improves the heat utilization ratio.

Description

The split pressure-bearing type whole glass vacuum tube solar energy can water heater

The utility model relates to the solar energy utilization technique field, particularly pressure-bearing type solar water heater technology.

Be on the pressure-bearing type solar water heater of heat collecting element with the all-glass vacuum thermal-collecting tube,, outside storage tank, connecting the heat collector that has heat exchange box by hot and cold water pipe for overcoming the defective that glass can not pressure-bearing.Arrange water circulating pump on cold water pipe or hot-water line, all-glass vacuum thermal-collecting tube communicates with heat exchange box, and arranges U type pressure pipe in each all-glass vacuum thermal-collecting tube, the two ends of each U type pressure pipe respectively be incorporated into heat exchange box in hot and cold water pipe be communicated with.

Because the characteristics of said apparatus are that each U type pipe connects hot and cold water pipe respectively, make processing, mounting process complexity easily to produce leakage in the junction, the more important thing is that heat conduction efficiency is low, influence the use of solar water heater.

The utility model purpose be to design a kind of technology simple, be convenient to install, split pressure-bearing type whole glass vacuum tube solar energy that heat utilization efficiency is high can water heater.

The utility model comprises storage tank, heat collector, heat collector mainly is made up of heat exchange box, all-glass vacuum thermal-collecting tube, be connected by cold water pipe, hot-water line between storage tank and heat exchange box, on cold water pipe or hot-water line, arrange water circulating pump, in all-glass vacuum thermal-collecting tube, establish U type pressure pipe, it is characterized in that adjacent U type pressure pipe is interconnected in heat exchange box, the U type pressure pipe at two ends is communicated with cold water pipe, hot-water line respectively.

Because adjacent U type pressure pipe is interconnected, be convenient to make, reduced and being connected of hot and cold water pipe, reduce the generation of leakage phenomenon, communicate with heat exchange box owing to vacuum heat collection pipe simultaneously, make solar day in the vacuum heat collection pipe when shining and medium intensification in the heat exchange box, because U type pipe is arranged in the vacuum heat collection pipe, the heat of medium reaches the interior water of U type pipe in the vacuum heat collection pipe, heated water in the U type pipe is by the water pump circulation, with the water heating of bearing water tank, increase heat conduction efficiency, improved heat utilization efficiency.

When heat transfer medium in the heat-exchanging water tank was water, heat exchange box was heat-exchanging water tank, and temperature-sensing probe is set respectively in storage tank and heat-exchanging water tank, and the circuit of two probes is connected on the ON-OFF control circuit of water pump.By the temperature difference in relatively storage tank and the heat-exchanging water tank, when water temperature difference surpassed setting value, water pump was opened work automatically, and when the temperature difference during less than setting value, pump switch is closed, and water pump is not worked, and reduces the idle work of water pump with this.When particularly water temperature was lower than in the storage tank water temperature in the heat-exchanging water tank, heat loss played a role in the storage tank to avoiding.

Now in conjunction with the accompanying drawings, further specify a kind of embodiment of the present utility model.

Accompanying drawing is the utility model structural representation.

Among the figure, 1 temperature-sensing probe (), 2 heat-insulation layers, 3 storage tanks, 4 outlet pipes, 5 water inlet pipes, 6 cold water pipes, 7 water pumps, 8 tailstocks, 9 all-glass vacuum thermal-collecting tubes, 10U type copper pipe, 11 heat-insulation layers, 12 heat-exchanging water tanks, 13 temperature-sensing probes (two), 14 hot-water lines, 15 pump switch controllers.

As shown in the figure, every U type copper pipe 10 inserts respectively in the every all-glass vacuum thermal-collecting tube 9, adjacent U type copper pipe 10 is interconnected in heat-exchanging water tank 12, the U type copper pipe 10 that is positioned at right-hand member is connected on the cold water pipe 6, and the U type copper pipe 10 that is positioned at left end is connected on the hot-water line 14 that is positioned at heat-exchanging water tank.

The port of hot-water line 14 in storage tank 3 is positioned at above the port of cold water pipe 16, and the port end of hot-water line 14 is provided with downward elbow.

Temperature-sensing probe (one) 1 and temperature-sensing probe (two) 13 are separately positioned in storage tank 3 and the heat-exchanging water tank 13.Above-mentioned two probe line are connected on the on-off controller 15 of water pump 7.
