Embodiment
For ease of understanding the technology contents of the present invention, the present invention is further described with reference to the accompanying drawings and examples.
The present invention is further described with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of winter water pipe anti-freezing type solar water heater of the present embodiment includes heat storage water tank 1, antifreeze
System, solar heat-collection plate 2, support 3；Heat storage water tank 1 is connected with heat supply water pipe 4 and enters cold water pipe 5；Wherein, winterization system bag
Include insulating tube 6, heat pipe 8, metal fin 7, electric heating cover 9, electrical heating controller 10, temp probe interface 11, wall 12, temperature
Probe 13, electrical heating switch 14, heat pipe 8 include condensation segment, adiabatic section and evaporator section, and heat supply water pipe 4 is with entering cold water pipe 5 and heat
The condensation segment of pipe 8 is placed in insulating tube 6 simultaneously, and the evaporator section of indoor heat pipe 8 is to absorb the heat in room air as insulating tube 6
Interior offer heat, while auxiliary electric heater unit：Electric heating cover 9, electrical heating controller 10 and electrical heating switch 14, are constituted antifreeze
System.Adiabatic section is in wall 12, and adiabatic section together reaches interior in insulating tube 6 through wall 12, and both separate indoors；Protect
Warm pipe 6 is used as heat-insulation layer in wall using the deformable insulation material such as hard polyurethane foam, rock wool.Heat pipe 8 using aluminium or
Iron material is as thermotube shell, the problem of to weaken or eliminate heat pipe short life that incompatibility is brought；Metal fin 7 is welded on
The evaporator section of heat pipe 8, increases heating surface area, to transmit more heats；The caliber of heat pipe 8 is 10cm, using deformability
Material does housing, it is ensured that have good pliability when mounted.The heat lift of condensation segment is rested in heat supply water pipe 4 for a long time
The cold water that the relatively low water of temperature and outdoor are entered in cold water pipe 5, prevents the waste of water pipe from freezing crack and cooled water discharge.To sum up, can be real
Existing low temperature is antifreeze and saves the double benefit of the energy.
The operation principle of this defroster：Hot water is after the outlet of solar water heater heat storage water tank 1 outflow, into supplying hot water
Pipe 4, winter is northern due to heating, and indoor temperature is higher, and outdoor temperature is relatively low, and indoor/outdoor temperature-difference is up to tens degrees Celsius, to rise
High water temperature, need to be transmitted from indoor heat Q, the evaporator section of heat pipe 8 is located at indoor and absorption chamber by heat pipe 8 as heat transfer carrier
After interior heat Q, it is warming up to saturation temperature and evaporates at such a temperature, transpiration rises to condensation segment in the presence of density contrast,
In condensation segment, because Working medium gas and the external world have the larger temperature difference, Working medium gas condenses and discharges heat Q to insulating tube 6 to the cold
Interior air, so that heat Q is further passed to the relatively low cold water of temperature by hot-air in insulating tube 6：Enter cold in cold water pipe 5
Water and the water at low temperature rested on for a long time in heat supply water pipe 4 so that heat supply water pipe 4 and the cold water temperature entered in cold water pipe 5 are high
In freezing point, it is not susceptible to freeze, while properly increasing the temperature of the initial ejection cold water in heat supply water pipe 5 when water heater is run
Degree, just with it is civilian, so as to reduce waste.If during bad environments, the heat Q provided by heat pipe 8 is insufficient for the heat of resident
Water is used, auxiliary electric heater unit：Electric heating cover 9, electrical heating controller 10, electrical heating switch 14, are heated by electric heating cover 9
The evaporator section of heat pipe 8 is when providing enough heat in insulating tube 6 to make the temperature of two water pipes meet use condition, to turn off electrical heating
Switch 14, reduces energy consumption.
As shown in Fig. 2 the operation principle schematic diagram of heat pipe 8：During work, the evaporator section of gravity assisted heat pipe is inhaled from the hot-air of surrounding
Heat Q is received, worker quality liquid, by thermal evaporation, forms saturated vapor on inside heat pipe liquid-vapour interface, and steam is worn from evaporator section
Cross adiabatic section to flow to condensation segment and condense on vapour-liquid interface of condensation segment, along with amount of heat Q' release, condensation
Section is with phase transformation convection type by nucleating flow, and heat is transferred to low-temperature receiver by way of heat conduction-free convection-heat conduction；And
Condensation water can be back to evaporator section without outside energy under gravity, re-start heat absorption-heat release circulation.In order to strengthen
Heat-transfer effect, is subject to some metal fins 9 outside evaporator section, such as aluminium or copper product, to increase heat transfer area, reaches high efficient heat exchanging
Purpose.
