Abstract
The utility model relates to a spiral pulsating heat pipe solar water heater and belongs to the fields of solar energy heat utilization, heat transmission and mass transmission. A pulsating heat pipe is formed by a corresponding straight pipe section and a corresponding spiral pipe section, and is filled with working substance occupying 50 percent to 70 percent of the total pipe volume under the vacuum state, so that liquid columns and air locks are formed therein in alternate distribution; and an evaporating section of the spiral pulsation heat pipe is located inside a vacuum glass pipe, a condensing section is located inside a water tank, and the water tank is communicated with the vacuum glass pipe and is filled with water. When in work, the solar water heater not only adopts the heat collection mode of the conventional vacuum glass pipe solar water heater, but also achieves remarkably higher heat collecting effect under the combined actions of sensible heat and hidden heat of the working substance inside the pulsating heat pipe, which results from the fact that due to the temperature difference between water in the water tank and the vacuum glass pipe, the working substance in the evaporating section of the pulsating heat pipe is evaporated and expanded to move towards the condensing section, and is in intense reciprocating oscillatory movements after being condensed; and the spiral pulsating heat pipe solar water heater has the characteristics of stronger heat transmission between the pulsating heat pipe and the water, as well as freezing protection.
Description
Technical field
The utility model belongs to solar thermal utilization and heat transfer, mass transfer technical field, particularly a kind of spiral pulsating heat pipe solar water heater.
Background technology
Building energy conservation is one of China's three big emphasis energy-saving field.In China existing 4 * 10
10m
2In the building, have 99% to belong to the highly energy-consuming building.Even new building still has to be the highly energy-consuming building more than 95%, China unit's architectural energy consumption is higher 2～3 times than the developed country under the equal weather conditions.Therefore, building energy conservation is China's " energy-conservation, reduce discharging " work important component part, carries out that building energy conservation has important practical significance and far-reaching significance.Carry out building energy conservation, except will developing energy-conservation construction material, a very important aspect is to develop regenerative resource energetically.Solar energy is the regenerative resource that can bring into play remarkable effect in building energy conservation.China is located in the abundant subtropical zone of sunlight, and is vast in territory, and solar energy year, radiation amount was above 5MJ/m
2, the area of year sunshine time above 2200 hours accounts for 2/3 of area, belongs to one of abundant country of solar energy resources.For this reason, researching and developing efficiently, solar energy heat collector has great importance.
Pulsating heat pipe PHP (Pulsating Heat Pipe) can be described as selfexcited oscillating-flow heat pipe SEMOHP (Self-Exciting Mode Oscillating-Flow Heat Pipe), oscillating flow heat pipe OFHP (Oscillating-Flow Heat Pipe) again or oscillating heat pipe OHP (Oscillating Heat Pipe) is Japanese scholar Akachi invention in 1994.It is that diameter is bent to the shape of being made up of some straight tubes and some elbows less than the metal tube of 5mm, encapsulation certain mass hydraulic fluid under vacuum condition.Because caliber is enough little, working media forms alternatively distributed vent plug and fluid column in the pipe under the effect of factors such as capillary force.By the difference of its circulatory system, can be divided into two kinds of the disjunct non-loop types of loop type and two ends that head and the tail are linked to be the closed-loop path.When pulsating heat pipe one end bringing-up section was heated, liquid in pipe was expanded by thermal evaporation, to other end condensation segment motion, and was condensed and emitted the latent heat of vaporization, became liquid state again, caused the very big pressure reduction of generation between cold and hot end.Because the solution-air plunger is interspersed, produce strong reciprocating vibration motion in causing managing.The ripple frequency of pulsating heat pipe is higher than the solution-air closed circulation frequency in the conventional heat pipe far away, and simultaneously, the heat transfer process between its working media and heat pipe wall is also strengthened greatly because of the effect that is subjected to violent pulsation.In addition, pulsating heat pipe also has simple in structure, does not need capillary wick, helps reducing cost; Heating location and mode of heating unrestricted (gravity assisted heat pipe commonly used necessary bottom heating); Can be arbitrarily crooked, applied widely; And caliber is little, and is in light weight, is easy to realize outstanding advantages such as microminiaturized and startup is rapid.But the also untapped solar water heater aspect that is applied to of prior art pulsating heat pipe.Shortcoming and defect such as caliber is big, weight is heavier so present solar water appliance has, complex structure, thermal starting are slow, cost height.
Summary of the invention
At the deficiencies in the prior art and defective, the utility model provides a kind of simple in structure, spiral pulsating heat pipe solar water heater that Heat-collecting effect is good.
The utility model is design like this: a kind of spiral pulsating heat pipe solar water heater, it is characterized in that, comprise water tank, condensation segment, cover plate, evaporator section, glass tube with vacuum, wherein be provided with the spiral pulsating heat pipe in glass tube with vacuum and the water tank, the spiral pulsating heat pipe divides condensation segment and evaporator section, described condensation segment is positioned at water tank, evaporator section is positioned at glass tube with vacuum, described water tank is connected by cover plate with glass tube with vacuum, described water tank is provided with import and outlet, described cover plate and water tank seal by rubber cushion, described cover plate and glass tube with vacuum pass through rubber sealing, described water tank main body adds heat-insulation layer, and described spiral pulsating heat pipe is the metal tube of internal diameter less than 5mm.
Pulsating heat pipe of the present utility model is formed loop by internal diameter less than respective straight pipeline section and the pigtail of 5mm, in order to absorb solar energy better, the certain angle of whole spiral pulsating heat pipe solar water heater inclination, during work except heat absorption mode with traditional glass tube with vacuum solar water heater, because there is the temperature difference in the water in glass tube with vacuum and the water tank, water in the glass tube with vacuum makes the working medium evaporation in the pulsating heat pipe evaporator section expand, move to condensation segment, and be condensed and emit the latent heat of vaporization, again become liquid state, cause under the effect of very big pressure reduction between evaporator section and the condensation segment, produce strong reciprocating vibration motion, in pulsating heat pipe under the acting in conjunction of working medium sensible heat and latent heat, make spiral pulsating heat pipe solar water heater compare with traditional glass tube with vacuum solar water heater, Heat-collecting effect is significantly improved.Because the spiral elasticity structure of pulsating heat pipe, the convection heat transfer' heat-transfer by convection process of water in pulsating heat pipe and the water heater has also been strengthened in the vibration of intraductal working medium during work.In addition, because the two-way heat-transfer character of pulsating heat pipe, can also prevent that in a way cold night in winter glass tube with vacuum is by bursting by freezing.So the utlity model has advantages such as simple in structure, that Heat-collecting effect is good, thermal starting is fast, processing cost is low, be convenient to implement development and use.
