Abstract
The utility model provides a vacuum tube solar collector capable of evacuation. The solar collector comprises a vacuum tube, a cold water pipeline, a hot water pipeline, a heat insulation plug, a water inlet pipe and a water outlet pipe, wherein the open end of the vacuum tube is sealed by the heat insulation plug; both the water inlet pipe and the water outlet pipe are inserted into the vacuum tube through the heat insulation plug; the water inlet pipe is communicated with the cold water pipeline; and the water outlet pipe is communicated with the hot water pipeline. As the collector can evacuate water in the vacuum tube, when the temperature is too high or the solar collector is not in use, water in the collector can be evacuated automatically or manually, so that water in a water tank is prevented from excessive temperature, and the collector can be kept dry when not in use, which prevents water in the collector from freezing to damage the vacuum tube due to too low external temperature.
Description
Technical field
The utility model relates to a kind of solar heat collector, especially a kind of vacuum tube solar heating element.
Background technology
No matter solar water heater is in industry or family expenses are all used widely.Heat collector is a core component of solar water heater.The heat collector that uses comprises header, vacuum tube, runner at present, and vacuum tube directly communicates with runner, utilizes the water in the solar energy heating vacuum tube, flows into water tank by runner again.For example: the patent No. is that disclosed heat collector and the patent No. are that disclosed heat collector all is this structure in the patent documentation of zl200820130243.7 in the patent documentation of zl03271275.8.
Though this heat collector is simple in structure, firing rate is very fast, and the water in the heat collector of this structure can not emptying, can not be antifreeze, can not prevent that water temperature is too high.The patent No. is to disclose a kind of technical scheme of using antifreezing agent in heat collector in the zl02118948 patent documentation, and still, cost is too high, and effect is not fine, uses inconvenience.
The utility model content
But the utility model provides a kind of vacuum tube solar heating element of emptying, because this heat collector can be with the water emptying in the vacuum tube, too high or when not using in temperature, but the water in the automatic or manual emptying heat collector, like this can be too high to prevent the coolant-temperature gage in the water case, can when not using, keep the heat collector drying again,, damage vacuum tube in order to avoid ambient temperature is crossed the water freezing that makes when hanging down in the heat collector.
Vacuum tube solar heating element of the present utility model comprises vacuum tube, cold water pipes, hot water pipeline, heat insulation plug, water inlet pipe and outlet pipe.The openend of vacuum tube seals with heat insulation plug, and water inlet pipe and outlet pipe insert in the vacuum tube by heat insulation plug respectively, and water inlet pipe communicates with cold water pipes, and outlet pipe communicates with hot water pipeline.
Preferably, in the described vacuum tube solar heating element, be provided with sealing ring between heat insulation plug and vacuum tube, water inlet pipe, the outlet pipe.
Preferably, in the described vacuum tube solar heating element, vacuum tube is a glass tube.
Preferably, in the described vacuum tube solar heating element, the hot and cold water pipeline is connected to a plurality of vacuum tubes.
Preferably, in the described vacuum tube solar heating element, be provided with temp probe in the vacuum tube, the temperature in the test vacuum tube prevents that water temperature is too high.
Preferably, in the described vacuum tube solar heating element, described cold water pipe is connected with control valve, but automatic or manual control aqueous reflux, with the water emptying in the vacuum tube.
Vacuum tube solar heating element of the present utility model can be with the water emptying in the heat collector, and it is too high to control temperature, again can be antifreeze, improved the service life of heat collector.
Description of drawings
Fig. 1 is that vacuum tube is arranged the embodiment schematic diagram in the utility model vacuum tube solar heating element;
The specific embodiment
Vacuum tube chain according to vacuum tube solar heating element shown in Figure 1 lists intention, and vacuum tube solar heating element of the present utility model comprises vacuum tube 1, cold water pipes 2, hot water pipeline 3, heat insulation plug 4, water inlet pipe 5, outlet pipe 6 and O RunddichtringO 7.The openend of vacuum tube 1 seals with heat insulation plug 4, water inlet pipe 5 and outlet pipe 6 insert in the vacuum tube 1 by heat insulation plug 4 respectively, water inlet pipe 5 communicates with cold water pipe 2 roads, outlet pipe 6 communicates with hot water pipeline 3, be provided with O RunddichtringO 7 between heat insulation plug 4 and vacuum tube 1, water inlet pipe 5, the outlet pipe 6, the hot and cold water pipeline is connected to a plurality of vacuum tubes 1.
In addition, vacuum tube 1 is a glass tube, puts into temp probe in the vacuum tube 1, test vacuum tube temperature; Cold water pipe 2 one ends are connected with magnetic valve, the control water (flow) direction.
The operation principle of vacuum tube solar heating element of the present utility model: cold water flows into vacuum tube 1 by cold water pipes 2 and water inlet pipe 5, heats, and heated hot water flows into hot water pipeline 3 by outlet pipe 6, flows into boiler by hot water pipeline 3 again.When not in use, can pass through control valve, automatic or manual makes aqueous reflux, and the aqueous reflux in the hot water pipeline 3 is flowed into vacuum tube 1 by outlet pipe 6, flows out vacuum tube 1 by water inlet pipe 5 again and flows to cold water pipes 2, discharges then.When the temperature that tests out when temp probe is too high, also can pass through control valve, automatic or manual makes aqueous reflux discharge heat collector.
The utility model is not limited to above-mentioned embodiment, and application, and every heating tube has adopted the heat collector of this emptying system all to fall into the protection domain of this patent.
