Abstract

The utility model discloses a recycle water solar heating device which contains a heat collecting device and a heat storage box. The heat collecting device is composed of a plurality of tubes positioned in the box body in parallel connection, and connects with the heat storage box via a closed pipeline. The heat storage box is a water container full of water, and the pipeline is arranged with a water pump and a motor control circuit. The utility model transforms the solar energy into the water inner energy by using the photothermic transition, and transmits the water inner energy to the heat storage box for saving up the heat energy by using an auto control circuit and a recycle water pump, at last adjusts and controls the heating speed according to the heat quantity required in the room to attain the purpose of heating. The thermal conversion ratio of the utility model can reach 40% and above. The utility model can store the energy in a period of sunny days as well as cloudy days and nighttime; and the invest is little, the service lift is long; the utility model is clean and sanitary with non-pollution; the temperature can be conveniently controlled and adjusted , the health of people can be benefited ; and a lot of unrenewable energy can be saved.

Description

The recirculated water solar heating device

(1) technical field

The utility model belongs to technical field of solar utilization technique, is specifically related to a kind of civil solar heating installation.

(2) background technology

Utilizing solar heating at present in the world is to adopt endothermic box with air heat in the case mostly, and it is indoor that hot-air is recycled in the free convection mode, and room temperature is raise.This mode solar energy utilization ratio is low, and only is fit to fine the use, and night and cloudy day also must be adopted the usual manner heating.Use more vacuum heat collection pipe solar water heater at present, vacuum tube will lean on the hydraulic pressure of running water that water is transported in the heating tube, and this device only adapts to the area that running water is arranged, and its upper and lower water pipe has freezing possibility in the winter of cold, and cost is higher, makes an investment in 1000 yuan/m ²More than, if utilize it to warm oneself, gross investment is at least more than 60000 yuan, general rural households are difficult to bear.

(3) summary of the invention

The purpose of this utility model provides a kind of recirculated water solar heating device, to solve rural households' heating and bathing and kitchen water are provided.The technical solution adopted in the utility model is: the recirculated water solar heating device comprises heat dump and the hot case of storage, and heat dump is to be made of many flat tube parallel connections that place casing, and it is connected with the hot case of storage by closed pipeline; Storing hot case is the water receptacle of filling water, and water pump and circuit for controlling motor are housed on the pipeline.

The utility model utilizes photo-thermal to transform the interior energy of conversion of solar energy for water, utilize automatic control circuit and water circulating pump that interior can being transported in the hot case of storage of water stored again, at last according to indoor needs heat how much regulate and control heat release speed, reach the purpose of heating.Heat conversion of the present utility model can reach more than 40%.Can be in certain time limit storage power, can not only be used for fine day, cloudy day and also can using night; Small investment, long service life, gross investment only needs more than 10,000 yuan, reaches service life more than 30 years; Sanitation and hygiene, non-environmental-pollution; Can conveniently control and regulate temperature, help the healthy of people; Can save a large amount of non-renewable energy resources.

(5) specific embodiment

The recirculated water solar heating device comprises the heat dump that places the roof and the indoor hot case of storage, there is heat-insulation layer 1 at the side of heat dump and the back side, the endothermic tube 2 of built-in many parallel connections, its housing is a metal framework, there is sheet iron at the back side, the front is a clear glass 3, and the heat-insulation layer at the side and the back side is done heat-insulating material with asbestos board and constituted.The some aluminum alloy flat tubes of endothermic tube 2 usefulness two ends are communicated with welding with pipe, coat carbon black at outer surface again and constitute.Storing hot case 5 can be communicated with formation with several big Plastic Drums, pack with heat-insulating material all around, above bed board do hott bed usefulness, the side leave the heat radiation window to indoor heat radiation, window size dispel the heat as required what can regulate.Heat dump is pressed 50m on the room ²Receiving area calculates, indoor two hot casees of storage, the about 3m of each volume of installing ³ Endothermic tube 2 is connected by the hot case 5 of pipeline 4 and indoor storage, and water pump 6 and exhaust outlet 7 and water heater 8 are arranged on the pipeline 4.Pump motor is connected to automatic control circuit, and circuit for controlling motor is by meeting power supply E behind the thermistor R1 serial connection electromagnet L1; Meet power supply E behind the thermistor R2 serial connection electromagnet L2; Armature B is arranged between two electromagnet, and there is fulcrum O the centre of armature B, and it can rotate around fulcrum O; The outer end of armature B connects an end of the K switch in the motor M circuit; Motor M meets AC power U through K switch.Resistance R 1 is put into the hot case of indoor storage, and R2 puts into heat dump on the room, and when temperature in the endothermic tube was higher than 10 ℃ of temperature in the hot case of indoor storage, circulating pump rotated automatically, the water in the hot case of storage is delivered on the room heated, and the water after being heated is back in the hot case of storage automatically.When the temperature in the endothermic box on the room was higher than 1 ℃ of temperature in the hot case of indoor storage, circulating pump quit work automatically, and the hot water in the endothermic box all returns in the hot case of indoor storage on the room simultaneously.
