Abstract
A solar water heater with passively circulated heat-conducting medium is composed of water tank, heat collector, circulating pipeline, heat-collecting heat-exchanging loop consisting of heat exchanger, liquid heat-conducting medium and electric pump. The electric pump conveys the heat-conducting medium to circulate in the heat-collecting heat-exchanging loop, and the heat-conducting medium heated by the solar energy enters the radiator in the water tank to radiate and heat water in the water tank. The position of the water tank is not limited by the position of the heat collector, and the water tank can be arranged indoors, has less heat loss and high heat efficiency and can be used in winter.
Description
The utility model belongs to solar water heater, the solar water heater of particularly passive circulating heat conduction medium.
Current, widely used solar water heater is the natural cycle solar water heater, comprise high-order insulation cyclic water tank, heat collector, frame and circulation line, heat collector absorbs solar energy and heats water in the heat collector, and the water that the thermal siphon pressure rice that utilizes the temperature difference of water to produce promotes in the whole water tank carries out the heat exchange circulation.Weak point because solar energy directly heats the water in the heat collector, makes the water Natural Circulation, the insulation cyclic water tank the position must be higher than heat collector, and the insulation cyclic water tank must be placed on the open air, loses heat is many, the thermal efficiency is low, and this water heater can not use in the winter time.
The novel purpose of this real sheet is to provide a kind of solar water heater of passive circulating heat conduction medium, directly heat liquid heat-conducting medium in the heat collector by solar energy, heat-conducting medium is by the passive circulation of external force, and the heat of its storage is by the water in the radiators heat water tank in the water tank.Because heat-conducting medium is passive circulation, the position of water tank can not be subjected to the restriction of heat collector position, and its thermal loss is few, thermal efficiency height, and this water heater can use in the winter time.
The utility model is achieved in that a kind of solar water heater of passive circulating heat conduction medium, comprise water tank, heat collector and circulation line, heat exchanger import of installing in water tank and outlet are communicated with formation thermal-arrest heat-exchanging loop by circulation line with the export and import of heat collector, in the thermal-arrest heat-exchanging loop, be filled with liquid heat-conducting medium, on the thermal-arrest heat-exchanging loop, electric pump be installed.
Electric pump delivering liquid heat-conducting medium on the utility model thermal-arrest heat-exchanging loop circulates in the thermal-arrest heat-exchanging loop, in heat collector, entered the radiator of installing in the water tank, the temperature of the water in the water tank is raise by radiator heat-dissipation by the liquid heat-conducting medium of solar energy heating.Because liquid heat-conducting medium passive circulation in the thermal-arrest heat-exchanging loop, the position of water tank can not be subjected to the restriction of heat collector position, can be placed in antifreeze place, so its thermal loss is few, thermal efficiency height, and this water heater can use in the winter time.
Accompanying drawing is the utility model structural representation, below in conjunction with accompanying drawing the utility model is further described, a kind of solar water heater of passive circulating heat conduction medium, comprise water tank, heat collector and circulation line, changing diffusing device (4) import and exporting by circulation line (2) of installing in water tank (5) is communicated with formation thermal-arrest heat-exchanging loop with the export and import of heat collector (1), heat exchanger (4) can be plate type heat exchanger or finned heat exchanger or coil heat exchanger, in the thermal-arrest heat-exchanging loop, be filled with liquid heat-conducting medium, liquid heat-conducting medium can be anti-icing fluid or conduction oil, electric pump (3) is installed on the thermal-arrest heat-exchanging loop, temperature element (7) is installed respectively in water tank (5) and in the heat collector (1), temperature element (7) can be a temperature sensor, temperature element (7) links to each other with controller (6) by lead, controller (6) is connecting electric pump (3) by lead, the operation of electric pump (3) and stop to control by controller (6), in the temperature in the heat collector (1) is higher than water tank (5) during the temperature of the setting of water, the temperature sensor that is contained in the heat collector (1) is passed to controller (6) with the temperature signal of heat collector (1), controller (6) starting electric pump (3) circulates liquid heat-conducting medium in the thermal-arrest heat-exchanging loop, by heat exchanger (4) temperature of water in the water tank (5) is raise, when the temperature difference of water drops to a certain degree when the water temperature in the water tank (5) reaches the temperature of setting or in temperature in the heat collector (1) and the water tank (5), temperature sensor is passed to controller (6) with temperature signal, controller (6) cuts off electric pump (3) power supply automatically, electric pump (3) stall, water tank (5) is in keeping warm mode, heat collector (1) is installed in outdoor, water tank (5) can be installed in environment temperature in above zero place, as be installed in indoor, water tank (5) is provided with water inlet pipe (8), outlet pipe (10) and overflow pipe (9), water tank (5) can be cancelled heat-insulation layer, reduced the cost of water tank, all very convenient to the cleaning and the maintenance of water tank.
Claims (6)
1, a kind of solar water heater of passive circulating heat conduction medium, comprise water tank, heat collector and circulation line, it is characterized in that diffusing device (4) import of changing of installing is communicated with formation thermal-arrest heat-exchanging loop with outlet by circulation line (2) with the export and import of heat collector (1) in water tank (5), in the thermal-arrest heat-exchanging loop, be filled with liquid heat-conducting medium, electric pump (3) is installed on the thermal-arrest heat-exchanging loop.
