Abstract

The utility model relates to a pressure-bearing type all weather solar heat collector for civil use. The whole solar heat collector is composed of a heat collection system and a water tank system, and boiled water and hot water are respectively supplied. Antifreeze type heat-transfer working media enter a spiral coil in the water tank system after heated in the heat collection system and forcedly circulates under the action of a pump, and the heat exchange between the working media and water is realized. Running water is controlled to fill or stop filling by a float ball type air breather, and a function of boiled water supply is realized by a boiled water tank. The utility model has the advantages of simple installation, convenient maintenance, good antifreeze property and low heat loss, and realizes a function of automatic control.

Description

The civilian round-the-clock solar heat collector of pressure-bearing type

The utility model relates to and a kind ofly utilizes that self pressure realizes adding water, the function that discharges water, and is suitable for the solar collector arrangement that the four seasons use.

Along with popularizing of solar heat collector, people are more and more deep realizes that this is pollution-free, energy-conservation, the necessity of high efficiency products.But there is following shortcoming in the heat collector that we use now: one, cistern system generally places on the roof, and volume is big, the installation, maintenance difficulty, and cause the roof drainage easily; Two, water temperature can not guarantee, particularly boiling water, hot water can not need provide respectively by the user; When three, using complete glass vacuum sun thermal-collecting tube to make absorber, directly add hot water, anti-freezing property in the winter time is poor.

The purpose of this utility model provides a kind of improved solar collector arrangement, and it can effectively realize the exchange heat of water in working medium and the cistern system in the collecting system, and boiling water, hot water are supplied with respectively, and realization adds the function of cold water automatically.

After the purpose of this utility model is achieved in that the heat-transfer working medium of anti-freeze type is heated to design temperature in collecting system, under the effect of pump, enter the spiral coil in the water tank, realize the heat transmission work between the two.Simultaneously, the heat-transfer working medium after temperature reduces is back to collecting system under forced circulation, heated again.Water in the cistern system, because of the difference of pressure, temperature high in the upper part, temperature low at position down.Be arranged in the boiled water tank in the cistern system and be provided with temperature controller, according to the temperature of setting, whether the water in the control boiled water tank emits by temperature controller.The cistern system upper part is equipped with the float-ball type air-breather, controls the adding of whole cistern system inner cold water or stops by the float-ball type air-breather.The float-ball type air-breather is made up of lightweight ball float, horn socket, wire netting.

The utility model is because cistern system separates with collecting system, so install simple, easy to maintenance; The heating of water is finished by the heat transfer type working medium of anti-freeze type and its heat exchange in the cistern system, has the advantages that resistance to frost is good, heat waste is little; Simultaneously, by the adding of float-ball type air-breather control whole system cold water and stop, having realized automation control, and simple and easy to do.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the schematic diagram according to the collecting system that the utility model proposes.

Fig. 2 is the profile according to the cistern system that the utility model proposes.

The generalized section of Fig. 3 float-ball type air-breather.

Describe the details and the working condition of the concrete device that the utility model proposes in detail below in conjunction with accompanying drawing.

The heat transfer work of anti-freeze type is stored in the coupling device (2) of cistern system, and vacuum tube or heat pipe (3) are installed in the both sides of coupling device (2) as heat transfer element.Vacuum tube or heat pipe (3) absorb solar radiation, and heat-transfer working medium is heated.After heat-transfer working medium is heated to uniform temperature, thermistor (4) passes to pump (7) with signal, and heat-transfer working medium flows out from effuser (5) under the effect of pump (7), enters in the spiral coil (9), under the forced circulation effect of pump, the water in working medium and the cistern system is realized the heat transmission.Heat-transfer working medium after the heat exchange flows back to coupling device from input pipe (1), heating once more, repetitive cycling.

Water level rises water in the water tank with the rising of temperature, makes the high water of temperature at high water level, and the low water of temperature is in low water level, naturally formation hydrothermal area and cold water area.Open boiling water mouth (15), hot-water mouth (16) respectively, can emit boiling water and hot water respectively, realize different purposes.When discharging water, running water constantly flows in the water tank by cold water pipe (6).When water level rises to a certain degree, lightweight ball float (12-1) in the float-ball type air-breather (12) rises with liquid level, when rising to certain limit, stops up the osculum of horn socket (12-2), the interior gas of ambient atmos and water tank no longer is communicated with, can not adds entry again in the water tank.When discharging water, lightweight ball float (12-1) descends with the decline of liquid level, unclamps the osculum of horn socket (12-2), and the interior gas of water tank is communicated with atmosphere, at this moment, can add water in water tank.

Boiler (11) is installed in the top of cistern system, and the water in bottom and the water tank is communicated with.Water in boiler (11) is heated pipe (10) when being heated to design temperature, and temperature controller is opened valve (14), and open boiling water mouth (15) this moment, can emit boiling water.When emitting water, according to law of connected vessels, the water of water tank upper constantly flows in the boiler (11), and when water temperature was lower than design temperature, temperature controller passed to information valve (14) equally, forbids the outflow of boiling water.

Be installed in boiling water mouth (14), hot-water mouth (16), cold water tap (17), the valve of slagging-off mouth (18) all has the function of water outlet outage.

Valve (8) is an anti-check-valves.When cutting off the water, prevent that the water in the water tank from flowing backwards in water supply pipe.When cutting off the water, can locate to emit cold water, use, if the long-pending incrustation scale that has in the water tank can be located to remove at slagging-off mouth (18) for household in cold water tap (17).
