In order to reduce the run time of circulating pump 30, to save power consumption, temperature difference controlling party is used in present embodiment Formula carrys out opening, stopping for control loop pump 30, heats the water in water tank and working media heat dissipation.Controller collection second temperature sensing The detection signal of device 52, three-temperature sensor 53, the detection letter based on second temperature sensor 52, three-temperature sensor 53 The water temperature of water tank 20, the temperature of working media in collecting plate 10 are obtained number respectively, when the temperature and water tank of working media Water temperature difference when reaching the first heat exchange threshold value, controller manipulate the first solenoid valve 71 it is electric by open circulation, the second electromagnetism 72 dead electricity of valve keeps blocking circulation, and above-mentioned heating pipeline connection, working media can circulate in heating tube stream, controller behaviour Vertical circulating pump 30 electric must be activated, and heat the driving force for being formed in pipeline and making working media flow, and working media flows through heat exchanger 21 heat the water in water tank 20 by way of heat exchange, until the temperature and water tank 20 of the working media of collecting plate 10 The difference of water temperature is stopped when reaching the second heat exchange threshold value, or is stopped when the water temperature of water tank 20 reaches the first above-mentioned preset value, control Device manipulation 71 dead electricity of the first solenoid valve is closed blocking circulation, second solenoid valve 72 keeps dead electricity to be blocked circulation, and described adds Pipe line and heat dissipation pipeline are blocked circulation, and controller manipulates 30 dead electricity of circulating pump and is stopped operating, and working media stops stream It is dynamic.So far, the process once heated to the water in water tank is completed.The first heat exchange threshold value is more than the second heat exchange threshold Value, for example, as a kind of optional scheme, wherein the first heat exchange threshold value be able to can take by 10 DEG C, the second heat exchange threshold value of value It is worth for 3 DEG C.That is, when the temperature of the working media in collecting plate and the difference of water temperature of water tank reach 10 DEG C, it is above-mentioned The circulation of heating pipeline, circulating pump 30 is activated, and working media circulation heat exchanger heats the water in all water tanks；When in collecting plate When the difference of the temperature of working media and the water temperature of water tank is less than 3 DEG C, circulating pump 30 is stopped, and above-mentioned heating pipeline is blocked Circulation, working media do not circulate to heat water.Using temperature difference control mode, the fortune of circulating pump 30 on the one hand can be efficiently reduced The row time saves electric energy；Another aspect temperature difference is bigger, and heat exchange efficiency is higher, when can efficiently reduce the operation of circulating pump 30 Between, further save power consumption.So repeatedly, the water in water tank is heated, water temperature ramps up.When the water in water tank When temperature reaches the first preset value, it will be appreciated that be to be not likely to produce any temperature value of incrustation scale, such as 65 DEG C, when working media temperature with For the difference of the water temperature of water tank when reaching the first above-mentioned heat exchange threshold value, controller will no longer manipulate heating pipeline circulation, not right Water in water tank is heated, so that it maintains the first preset value, to avoid being produced on the inner wall and heat exchanger of water tank Incrustation scale.

Further, during controller noted above manipulates heating pipeline heating water, the controller also gathers second The detection signal of flow sensor 62, the detection signal acquisition water flow value based on the second quantity sensor 62.Work as working media Temperature and water tank water temperature difference when reach the first heat exchange threshold controller manipulate heating pipeline connection heating water process In, when water flow value is not zero value, i.e. when with water, controller manipulates heating tube roadlock disconnection and leads to user, suspends to storage Water in water tank is heated, and can such as be manipulated circulating pump 30 and be closed, and can also be manipulated the first solenoid valve and be blocked circulation, with pause Heat exchange water；When water flow value is null value, i.e., user's useless water when, then manipulate heating pipeline connection and continue to water tank Interior water is heated.So control, can avoid the formation of the situation of user side waterside heating, cause water more higher with water temperature, Need ceaselessly to adjust the ratio of hot water or cold water, bring inconvenience.During above-mentioned pause heat exchange water, if work When making the temperature of medium and being higher than the second above-mentioned preset value, controller manipulates heat dissipation pipeline circulation, and working media flows through radiator Cooling, stops when the temperature of working media is less than the second preset value, stops when preferably dropping to three following preset values, favorably Opening, stopping number for circulating pump 30 is reduced, heat dissipation pipeline is manipulated and blocks circulation, stop heat dissipation；Second preset value can be regarded as thermal-arrest Working media permitted maximum temperature when plate works normally.So control, can collect to avoid working media because of high-temperature gasification High pressure is formed in hot plate, causes collecting plate to damage, or even explosion.

During stopping heat exchange when the water temperature of above-mentioned water tank 20 reaches the first preset value (such as 65 DEG C), it is Working media is avoided because high temperature damages collecting plate, when the water temperature of water tank 20 reaches work in the first preset value and collecting plate 10 When making the temperature of medium and being higher than the second above-mentioned preset value, the second preset value is more than the first preset value, for example, as a kind of optional Scheme, the second preset value can value be 115 DEG C, the first preset value can value be 65 DEG C, expression do not produce the preferable of incrustation scale Temperature, can be effectively prevented from the sediment incrustation on 20 inner wall of water tank and heat exchanger 21, and controller manipulates the first solenoid valve 71 and loses Electricity remains turned-off blocking circulation, second solenoid valve 72 obtains electric-opening and forms circulation, and the heat dissipation pipeline forms the path of circulation, Controller manipulates circulating pump 30 and electric must be activated, and under the suction driving of circulating pump 30, generation makes working media along heat dissipation pipeline The driving force of flowing, working media flow through radiator 40 and air heat-exchange along heat dissipation pipeline, and the temperature of working media is lowered, shape The working media relatively low into temperature, the relatively low medium of the temperature are back in collecting plate 10 through the suction of circulating pump 30, so circulation, Stop when the temperature of the working media in collecting plate reaches three preset values, controller manipulates 72 dead electricity of second solenoid valve and closed Impatency cutout is logical, 71 dead electricity of the first solenoid valve keeps blocking circulation, and the heat dissipation pipeline is blocked, and controller manipulates circulating pump 30 dead electricity stop motions, working media do not flow.So far, the process for once making working media radiate, the temperature of working media are completed Degree is reduced in safe temperature range, to avoid working media because high-temperature gasification forms high pressure in collecting plate, causes collecting plate Damage, or even explosion, the favourable service life for extending collecting plate.When 3rd preset value can be regarded as collecting plate normal work Any relatively low temperature value that working media is allowed, in order to reduce the number of starts of circulating pump 30, to save electric energy, the 3rd is pre- If value can value for slightly above the first preset value a certain value, for example, optional be higher than 10 DEG C, if the first preset value value is 65 DEG C, then the 3rd preset value can value be 75 DEG C.

Wherein, the radiator 40, as shown in Fig. 2, being at least made of heat-dissipating pipe 41.The heat-dissipating pipe 41 is along helix Direction extends from the top down, and the axis of the helix of heat-dissipating pipe 41 is uprightly arranged, the lower end of heat-dissipating pipe 41 is the defeated of working media Entrance, upper end are the delivery outlet of working media.The higher working media of temperature in collecting plate 10 is under being located at of heat-dissipating pipe 41 The input port at end flows into, and working media flows from bottom to top along heat-dissipating pipe 41, and heat-dissipating pipe 41 exchanges heat with extraneous air, and work is situated between The temperature of matter reduces, and forms the relatively low working media of temperature, and is flowed out from the delivery outlet positioned at upper end of heat-dissipating pipe 41, through circulation Pump 30 is back to the interior of collecting plate 10.Air at where radiator 40 is reduced by heat exchange, the atmospheric density in the region, Under the action of gravity, the less hot-air of density floats, and density big cold air in periphery flows downward, and forms free convection stream , heat dissipation effect is improved, enhances the radiating efficiency of working media.Inventor pass through experimental studies have found that, when radiator 40 Heat-dissipating pipe 41 uprightly arrangement, the higher working media of temperature flowed into from lower end, upper end outflow when, the intensity of free convection is most Greatly, the heat dissipation effect of radiator is best, and when the working media is produced identical temperature drop, the run time of circulating pump 30 is more It is few, it is beneficial to save energy expenditure.In addition, radiator 40, in same heat radiation power, the volume of radiator 40 can be made more It is small, it is favourable to save material and reduce cost.The material of the heat-dissipating pipe 41 may be selected as copper.
