Description
Technical field
The utility model 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, courage usually.The heat exchange efficiency of wall-type heat exchange water tank is low, gets heat few, is the principal element that causes water not hot.Due to after water tank startup electrical heating, in courage, courage, liner of jacket or coil heat exchange etc. can absorb the heat of hot water in water tanks, cause heat to flow backwards, thereby make the water heater energy-saving effect have a greatly reduced quality simultaneously; Need adopt during next wall-type heat exchange and add anti-icing fluid as medium, operation needs reach with medium circulation the purpose that prevents that the cold district pipeline from freezing.But add the essential special-purpose charging pump of medium, irregular liquid feeding, fluid infusion all need the professional to complete, 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 is all 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, circulate not smooth, collecting efficiency reduces; Because circulation area is excessive, hot spot increases simultaneously; During the cold snap operation, easily icing bombing, have a strong impact on the product operational reliability.
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 housing, install heat-absorbing plate core below 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, the 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 runners 32 UNICOMs, heat-pipe medium 5 is housed in 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.
The utility model content
The technical problems to be solved in the utility model is for the heat pipe flat plate collector that occurs on 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 utility model 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 heat exchange by water inlet pipe, even with the water tank bottom cold water mix, realize heat cycles.
the utility model 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 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 water tank is positioned at the top of water tank, 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 by circulation pipe, enter water tank through after heat exchange by water inlet pipe, even with the water tank bottom cold water mix, realize heat cycles.
In above-mentioned two schemes, except having requisite water inlet pipe and outlet pipe, can also have electrically heated heating rod in water tank.
The utility model has the advantage of:
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 utility model adopts is that the suction side of circulating pump is in the water-heater water tank inner tip, can be deposited on the water-heater water tank bottom after being heated due to incrustation scale, avoid the incrustation scale in water-heater water tank to enter flat plate collector, even fouling is slightly 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 due 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, therefore in low temperature environment, due to the vacuum insulation of heat pipe, strengthen 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 water tank, owing to there not being the partition heat exchange structure, the water tank weight reducing, easy for installation, reduced simultaneously the holistic cost that water-heater system configures.
