Abstract
The utility model relates to a heat exchanging and evacuating device for a heat conducting type solar water heater. The upper part of a water tank is connected with a water overflowing pipe, and a vent pipe is connected above the water overflowing pipe. One end of a water pipe, which penetrates through the upper part of the water tank, is positioned at the bottom in the water tank, and an evacuating and limiting pipe is connected above the water pipe. A coil pipe is arranged in the water tank, and a heat conducting agent inlet pipe and a heat conducting agent outlet pipe are respectively connected with the coil pipe. An expander which is communicated with the heat conducting agent inlet pipe is positioned above the heat conducting agent inlet pipe. The evacuating and limiting pipe and the water pipe are respectively connected with an evacuating valve and a water valve. The utility model has the advantages of high heat conducting efficiency, convenient operation and use, etc., and has the advantages of preventing freezing and preventing block caused by ice, etc.
Description
The utility model relates to solar water heater, especially a kind of device that utilizes the thermal conducting agent heat exchange and the water in the pipeline is carried out automatic emptying.
The solar water heater of prior art generally all is that water is directly shone heat, directly circulation.The heat-conducting solar water heater has plenty of the thermal-arrest plate is put in the glass-vacuum tube, does not need heat exchanger; Have plenty of and lower boiling thermal conducting agent is shone thermal current that the back produces through the sun pass through water in the heat exchanger heats water tank.In addition, generally be on water tank, to be connected with water overflow pipe and upper and lower conduit, its weak point is that heat energy utilization is low, the heat exchange weak effect, the water in the water tank easily freezes, even when winter solar light is relatively good, can be with the water heating of water tank, but since from outdoor attemperater to indoor ventilating water pipe, it is stifled to only depend on insulation to occur ice sometimes in the winter of cold, influence even destroy solar water heater use in the winter time.
It is good that the purpose of this utility model provides a kind of heat-transfer effect, do not freeze and heat exchange of heat-conducting solar water heater and emptier that handled easily uses.
The purpose of this utility model can realize by following measure: be connected with the water overflow pipe on the top of water tank, one end of water pipe by water tank top and be positioned at the bottom of water tank, the top of water pipe is communicated with the emptying position-limiting tube, be provided with coil pipe in the water tank, thermal conducting agent inlet tube and thermal conducting agent outlet are connected with coil pipe respectively, be positioned at the thermal conducting agent inlet tube above the expander that is communicated with the thermal conducting agent inlet tube is arranged.
The purpose of this utility model also can realize by following measure: emptying position-limiting tube and water pipe are connected with exhaust-valve and water valve respectively; Above the water overflow pipe, be communicated with tracheae; On expander, be connected with the thermal conducting agent position-limiting tube.
Working condition of the present utility model is as following:
Thermal conducting agent enters coil pipe in the water tank by solar heat-collection plate heat absorption back by the thermal conducting agent inlet tube, in the water when heat energy is released to coil pipe outside after, return the thermal-arrest plate under circulation by the thermal conducting agent outlet again and absorb heat, thus the circulation of formation thermal conducting agent.Owing to be provided with expander and the thermal conducting agent position-limiting tube that links to each other with expander, thereby guarantee the normal circulation of thermal conducting agent.
Open water valve, close exhaust-valve, running water injects water tank by water pipe, gas in the water tank is discharged by tracheae, and after cistern water level reached requirement, the water of excess was discharged by the water overflow pipe, should stop water filling to show, simultaneously, because tracheae is communicated with the water overflow pipe, stops not have in the water overflow pipe after the water filling and accumulate water.Open exhaust-valve, air is entered by the emptying position-limiting tube, and the water in the water pipe is excluded automatically.
When needing to use hot water, close exhaust-valve, open water valve, hot water is flowed out by water pipe, and water level descends in the water tank, and air enters by tracheae.When stopping to use hot water, open exhaust-valve, the water in the water pipe is excluded automatically.
The utility model is not owing to accumulate water in water pipe and the water overflow pipe, thereby avoided winter extraneous pipeline ice stifled, again because that the flow heat-exchanger rig heat-transfer effect of thermal conducting agent of inner loop is set in the water tank is good, simultaneously, prevented the generation of freezing phenomenon, in addition, simple in structure, operation and use are all convenient.
Fig. 1 is a schematic diagram of the present utility model
Wherein: 1-tracheae, 2-emptying position-limiting tube, 3-water tank, 4-coil pipe, 5-water overflow pipe, 6-thermal conducting agent inlet tube, 7-thermal conducting agent position-limiting tube, 8-thermal conducting agent outlet, 9-water valve, 10-exhaust-valve, 11-water pipe, 12-expander.
