Background technology
Existing gravity assisted heat pipe formula solar vacuum-tube water heater mainly is made up of gravity assisted heat pipe formula vacuum tube, storage tank, support etc.
The operation principle of gravity assisted heat pipe formula solar vacuum-tube water heater is: gravity assisted heat pipe formula vacuum tube is divided into following evaporator section and top condensation segment.Following evaporator section is made up of inside and outside two layers of concentric glass round tube, and outer pipe is a transparent glass tube, and solar energy passes outer layer glass tube with very high transmissivity.The inner layer glass tube outer surface scribbles the coating that absorbs solar energy, and the space between interior pipe and outer tube is evacuated, and absorbs scattering and disappearing of heat to stop internal layer.Evaporable liquid is housed in the inner layer glass tube, and sunshine passes outer tube and is absorbed by the inner tube outer surface coating, and the heated liquid in the inner tube becomes steam.Steam rises to condensation segment, and condensation segment is the extension of pipe in the evaporator section, has only one deck glass tube, and outer surface does not absorb the coating of solar energy.Condensation segment inserts in the water heater storage tank, contacts with cold water in the water tank.The steam that is risen to condensation segment by evaporator section is cooled to liquid by the cold water in the water tank, emits heat cold water to cold water, and the evaporator section below coagulating liq flows back under the gravity effect carries out periodic duty.
Absorb solar energy at evaporator section and become steam, steam in the condense process of heat release of the section of condensing water in water tank through what working medium in the heat pipe was gone round and begun again, water temperature constantly rises in the storage tank, thus acquisition hot water.
The evaporator section of gravity assisted heat pipe formula solar energy vacuum tube is a major part, and the condensation segment proportion is less.The contact area of evaporator section and its internal liquid working medium is big more, and then the area of heating liquid working medium is big more, and more liquid working substance can become steam, and water heater is high more to the utilization ratio of solar energy.
For guaranteeing that gravity assisted heat pipe can operate as normal, fill the liquid working substance amount in the heat pipe and can not surpass 25% of pipe inner volume.That is to say that if liquid in pipe working medium does not become steam, evaporator section has 75% area not touch liquid working substance.After evaporator section produced steam, steam rose to condensation segment and is cooled into liquid.Liquid flows back into evaporator section downwards; When liquid flows downward in tilted-putted cylindrical vacuum tube; Under the gravity effect, be concentrated in the downside of vacuum tube, and the flow of condensate liquid is very little, this just causes evaporator section only on the very small size of downside, to contact with condensate liquid.The upside of evaporator section is by solar light irradiation, and downside can not shined upon.Promptly with evaporator section under the condensate liquid of side contacts can not absorb heat and produce steam, the evaporator section upside can not be condensed liquid cooling but, is in empty solarization state, temperature can sharply raise.Also there is same problem in the liquid working substance that is positioned at the evaporator section bottom, because under the tilted-putted situation of vacuum tube, the liquid of evaporator section bottom more touches the downside surface that does not absorb heat, and upside heat absorption surface can not be in empty solarization state by liquid cools.
Therefore, gravity assisted heat pipe formula vacuum tube at most only has 25% evaporator section area to contact and produce steam with liquid, and 75% area can not produce steam by heating liquid.This makes that the efficient of this vacuum tube collection solar energy is lower, and The actual running results proves that the efficient that gravity assisted heat pipe formula vacuum tube is collected solar energy is lower than ordinary vacuum tube.And the evaporator section 75% not area of contact liq is in empty solarization state, and temperature is very high, and this can damage this coating that partially absorbs solar energy, causes vacuum tube to damage.
Summary of the invention

Described support is that the assembling of storage tank and vacuum tube provides support, and keeps the stable of solar water heater, and makes the correct direction of vacuum tube maintenance with abundant absorption solar energy.Supporting plate is from supporting in the face of vacuum tube down and fixing.Sealing ring is used for preventing that the water in the storage tank from passing through the slot leakage between vacuum tube condensation segment and storage tank.
The inner surface of in evaporator section, managing is along the axial arranged wick of pipe.Accumulate in the liquid refrigerant of evaporator section bottom, and the condensate liquid that flows back to of condensation segment, under the effect of wick capillary force, be full of all wick.Wick is gathered at the evaporator section inner surface, so the evaporator section inner surface is all moistening by liquid working substance.The effect of wick is exactly that the liquid refrigerant of some position of pipe in originally accumulating in is redistributed, and makes the inboard all surface of evaporator section can both be wetting by liquid refrigerant.
The water heater of the utility model has to start and does not produce dirt, vacuum tube in fast, the vacuum tube and be difficult for booster, not easy freezing, advantage that heat transfer efficiency is high.Simultaneously; The utility model has been arranged wick at the inner surface of vacuum tube evaporator section, and these wick can be so that the liquid refrigerant in the pipe be moistening with the whole inner surfaces of evaporator section, and whole heat absorptions surface of evaporator section can both touch liquid working substance and produce steam; Therefore; The solar water appliance that the utility model proposes has higher efficient, and the heat absorption surface of vacuum tube can not form high temperature and damage, thereby has overcome two major defects that existing gravity assisted heat pipe formula solar vacuum-tube water heater exists.
