Abstract
Disclosed is a solar energy water heater of vacuum glass cover heat pipe plane type, comprising tank consisted of thermal insulating material and outer gimbal, vacuum plane glass above the tank, absorber plate consisted of heating pipe and fin, condensing zone of the heat pipe and recycling water tank are connected, the water tank and water storage are connected or the condensing zone of heat pipe is directly connected to water storage, and absorber plate is under the vacuum plane glass. The invention has no problems of icing, scale formation and atmospheric corrosion, fairly good red flared radiation can be emitting from heat collector inside because of high level of transparency of the vacuum plane glass to sun radiation but opaque to red flared radiation, decreasing radiation heat loss to absorber plate. Besides, heat pie has fast start-up, high sensitiveness, wide work range, fast heat transfer, only oneway heat exchange between heat collecting pie, and when the sun radiation is fairly low, heat elimination of heating working substance to environment can be reduced.
Description
Technical field
The present invention relates to a kind of vacuum glass-covered board heat pipe solar water heater.
Background technology
Now general vacuum pipe solar water heater has following problem to need to be resolved hurrily through being extensive use of for many years on the domestic market: 1. in-tube fouling problem.Because in heat collecting pipeline, circulate throughout the year, cause scaling in the pipe, incrustation scale has hindered heat transfer, and the efficient of heat collector is obviously descended.Especially in the rural area, very poor because of water quality, cause collector efficiency growth in time to descend very fast.2. ice formation issues in managing.In the winter of severe cold, the water in the heat collecting pipeline build-ups ice, and volume swells, and causes the pipeline spalling.3. thermal-collecting tube internal memory dilutional hyponatremia, water temperature rises slowly, and the hot water in the pipe can't all take out, and the pressure that can not bear in the tap water pipe line system easily bursts.4. the absorber of electron tubes type solar thermal collector is not that compact arranged vacuum tube is formed by some, in Qian Hou quite a while, though there is quite a few energy to be received by daylighting face, does not enter into absorber at noon.5. surperficial heat waste is big.6. vacuum pipe solar water heater can not be made the building block overall structure and building combines.These problems have been brought a lot of inconveniences to the consumer, have influenced this energy-conserving and environment-protective product to a certain extent in the In The Heart of The Consumers image, directly have influence on further developing of whole solar energy industry simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of vacuum glass-covered board heat pipe solar water heater.
It has casing that insulation material and housing form, is provided with vacuum flat glass above casing, be provided with the absorber plate that heat pipe and fin are formed in the casing, the condensation segment and the cyclic water tank of heat pipe join, cyclic water tank and water storage tank join, perhaps the condensation segment of heat pipe directly and water storage tank join, absorber plate places below the vacuum flat glass.
The present invention adopts vacuum flat glass technology and hot pipe technique simultaneously on solar water heater, other has designed split type cisten mechanism.That vacuum glass cover plate heat-pipe flat-plate type water heater of the present invention does not exist is icing, fouling and air corrosion problem.Vacuum flat glass is high transparent to solar radiation, and is opaque to infra-red radiation, can launch the infra-red radiation that comes from heat collector inside preferably, thereby the radiation heat loss of absorber plate has been played the containment effect; In addition, because of having, heat pipe starts soon, highly sensitive, working range is big, heat transfer rate is fast, have only unidirectional exchange heat (thermal diode effect) and hot water not to have mass exchange between heat collector and the storage heater without thermal-collecting tube, when solar irradiation is low, can reduce being heated working medium and dispelling the heat towards periphery, reduce heat loss especially at night greatly.Split-type structural can improve heat exchange efficiency, easier and architecture-integral.The present invention can the four seasons be suitable for, be not afraid of freeze, can pressure-bearing, manufacturing process is simple, collecting efficiency is high, good heat insulating and the solar water heater that combines with the building one.

The specific embodiment
The heat pipe of vacuum glass-covered board heat pipe solar water heater of the present invention is a gravity assisted heat pipe, fin and heat pipe welding.Heat pipe is heat collector thermal-arrest and heat transfer element, can transmit a large amount of heats by a very little area.Heat pipe utilizes the evaporator section of working medium and condensation segment to transmit heat.Evaporator section is placed on thermal source such as the sun absorbs heat down, and the liquid phase hydraulic fluid absorbs the latent heat of vaporization and evaporates, and the other end of heat pipe is that condensation segment is cooled off by low-temperature receiver, and as the water in the water tank, hydraulic fluid is emitted the latent heat of vaporization.Condensate liquid relies on the gravity of self to turn back to condensation segment, does not need additionaling power and working medium circulates voluntarily.The work of gravity assisted heat pipe has certain directionality, and evaporator section must place the below of condensation segment, so just can make condensate liquid rely on the gravity of self to be turned back to evaporator section.Heat pipe dependence self internal work liquid phase-change is realized conducting heat, and it has good isothermal, and axially temperature drop is very little; Performance with thermal diode only allows hot-fluid to flow to a direction, and does not allow to flow in the opposite direction.
The water heater of vacuum glass-covered board heat pipe solar water heater of the present invention.Include the outer case of absorber plate, insulation material and the metal frame composition of water storage tank, heat pipe and fin composition, the seal frame that vacuum flat glass is formed.Be fixed with a plurality of heat pipes in the framework, each heat pipe is arranged parallel to each other, and the quantity of heat pipe is decided on demand.The absorber plate that heat pipe and fin are formed places below the vacuum flat glass.Whole water heater all adopts the polyurethane insulation material, has used mold pressing bubble filling process to solve and has contracted, takes off problem, promptly at casing external reinforcement fixed mold, with the excessive filling of foamed material.Around vacuum flat glass, compress, fix, and be coated with glass cement and the anti-water-leaking structure of use with rivet with angle bar.Heat pipe should put sealing rubber ring earlier before inserting the water storage tank water tank on heat pipe.Adopt the vacuum glass-covered board heat pipe solar water heater of cyclic water tank, heat pipe should put sealing rubber ring earlier before inserting the circulating box water tank on heat pipe.Cyclic water tank and heat collector are made of one, and cyclic water tank is by being connected with water storage tank into and out of two circulating water pipes.
Vacuum glass-covered board heat pipe solar water heater operation principle of the present invention is: after solar energy sees through vacuum flat glass, the flat plate heat tube that solar energy is scribbled surperficial absorber coatings absorbs, heat pipe reaches operating temperature (more than 30 ℃), phase transition process by internal working medium flows to cyclic water tank rapidly with heat, cyclic water tank carries out heat exchange (or the phase transition process of internal working medium directly flows to water storage tank rapidly with heat) with water storage tank again, heat collector bottom and being incubated with heat-insulating material all around, has only unidirectional exchange heat between heat collector and the cyclic water tank (or water storage tank), without any mass exchange.
