Description
Technical field
The present invention relates to solar water heater, specifically a kind of flat plate collector solar water heater.
Background technology
Present classic flat-plate solar water heater, its heat storage water tank adopts the wall-type heat exchange mode such as courage or coil pipe in liner of jacket, the courage usually.The heat exchange efficiency of wall-type heat exchange water tank is low, and it is few to get heat, is the principal element that causes water not hot.Simultaneously because after water tank started electrical heating, courage, liner of jacket or coil heat exchange etc. can absorb the heat of hot water in the water tanks in the courage, cause heat to flow backwards, thereby so that the water heater energy-saving effect have a greatly reduced quality; Need adopt during next wall-type heat exchange and add anti-icing fluid as medium, operation needs reach the purpose that prevents that the cold district pipeline from freezing with medium circulation.But add the essential special-purpose charging pump of medium, irregular liquid feeding, fluid infusion all need the professional to finish, and complex operation can't be known capacity simultaneously.After the operation of system long term high temperature, medium also can evaporate gradually, and problem maximum concerning the user is exactly: do not know what of dielectric capacity when to need liquid feeding, fluid infusion, product is safeguarded to the user in the future and is caused very burden.
If flat plate collector is direct and the water tank heat exchange, because the flat plate collector that often uses all is common " H " type and " S " type thermal-collecting tube structure all the time, be full of water in " H " type and " S " type thermal-collecting tube, and the thermal-collecting tube caliber is little, and the pipe resistance is large, and velocity flow profile is uneven, directly and after the water tank heat exchange, cause thermal-arrest tube wall local scaling, it is not smooth to circulate, and collecting efficiency reduces; Because circulation area is excessive, hot spot increases simultaneously; Easily icing bombing has a strong impact on the product operational reliability during cold snap operation.
In recent years, the research of people's opposite heat tube flat plate collector day by day deeply, the application of heat pipe flat plate collector also increases gradually, as shown in Figure 1, be a kind of structure chart of heat pipe flat plate collector, this heat pipe flat plate collector comprises housing, and the safety glass of high printing opacity is embedded in above the housing, install heat-absorbing plate core below the safety glass, heat-absorbing plate core comprises UNICOM's collector 1, heat exchanger tube 2 and thermal-collecting tube 3.Thermal-collecting tube 3 comprises the thermal-arrest fin 34 of thermal-arrest runner 32 and setting and thermal-arrest runner 32 both sides.Heat exchanger tube 2 is arranged on the inside of UNICOM's collector 1, and the tail end of heat exchanger tube 2 and head end stretch out outside UNICOM's collector 1 two ends of upper UNICOM collector 1 and heat exchanger tube 2 sealings.Upper UNICOM collector 1 be positioned at thermal-arrest runner 32 the top and with several thermal-arrest runner 32 UNICOMs, heat-pipe medium 5 is housed in the thermal-arrest runner 32.
What the most emerging this heat pipe flat plate collector only had heat exchanger tube 2 interior storages is water, and heat exchanger tube 2 is smooth straight tubes, and caliber is larger, and therefore the pipe resistance is less, and velocity flow profile can be even.
Summary of the invention
The technical problem to be solved in the present invention is for the heat pipe flat plate collector that occurs on the market, and the applicant proposed a kind of high efficient heat exchanging, prevent fouling and antifreeze and structure is simpler, the efficient heat pipe flat plate collector solar water heater of easy to install, cost.
The present invention solves the problems of the technologies described above by the following technical solutions: a kind of efficient heat pipe flat plate collector solar water heater, comprise heat pipe type flat plate solar collector, water tank, also comprise control system, the port of export of the heat exchanger tube of described heat pipe type flat plate solar collector is connected with the water inlet pipe of water tank, the entrance point of the heat exchanger tube of heat pipe type flat plate solar collector is connected with the hot water outlet pipe of water tank by a circulating pump, control system is connected to circulating pump, with circulating pump the hot water of water tank internal upper part is flow to the heat exchanger tube of heat pipe flat plate collector by control system, enter water tank through after the heat exchange by water inlet pipe, even with the water tank bottom cold water mix, realize Heating Cyclic.
The present invention also provides the efficient heat pipe flat plate collector solar water heater of another kind of structure, comprise heat pipe type flat plate solar collector, water tank, also comprise control system, has water inlet pipe in the described water tank, outlet pipe and circulation pipe, the port of export of the heat exchanger tube of described heat pipe type flat plate solar collector is connected with the water inlet pipe of water tank, the entrance point of the heat exchanger tube of heat pipe type flat plate solar collector is connected with the circulation pipe of water tank by a circulating pump, the mouth of pipe of the circulation pipe in the water tank is positioned at the top of water tank, with circulating pump the hot water of water tank internal upper part is flow to the heat exchanger tube of heat pipe flat plate collector by circulation pipe by control system, enter water tank through after the heat exchange by water inlet pipe, even with the water tank bottom cold water mix, realize Heating Cyclic.
In above-mentioned two schemes, except having requisite water inlet pipe and outlet pipe, can also have electrically heated heating rod in the water tank.
The invention has the advantages that:
1, high efficient heat exchanging: the water of this structure direct circulation heating water tank, there is not the filling of the heat exchange of water tank partition and antifreeze medium, maintenance is simple and heat exchange efficiency is high, gets heat than present " H " type and " S " type flat plate collector unit are and improves 30%.
2, solve present flat plate collector fouling and antifreeze problem: the scheme that the present invention adopts is that the suction side of circulating pump is in the water-heater water tank inner tip, owing to can be deposited on the water-heater water tank bottom after incrustation scale is heated, avoid the incrustation scale in the water-heater water tank to enter flat plate collector, even slightly fouling is arranged, because heat exchanger tube adopts smooth straight tube, incrustation scale is washing away and flowing and can't deposit in the heat exchanger tube of heat pipe flat plate collector owing to circulating pump in heat exchanger tube.Again because the heat exchanger tube of this heat pipe flat plate collector and water heat exchange interts in monoblock heat pipe flat plate collector, so in low temperature environment, because the vacuum insulation of heat pipe strengthens resistance to frost.
3, simple in structure, easy for installation, cost: the structural member that does not need to arrange in addition the partition heat exchange needs such as inner bag or coil pipe in the water tank, owing to there is not the partition heat exchange structure, the water tank weight reducing, easy for installation, reduced simultaneously the holistic cost that water-heater system disposes.
