Description
Technical field
The utility model relates to solar energy heat collection equipment, particularly a kind of heat pipe type vacuum pipe solar energy air heat collector.
Background technology
The heat exchange mode that present vacuum tube air collector adopts generally is to insert U type metal tube in vacuum tube, by flowing of U type air in tube the heat of vacuum tube absorption being taken away, is 200420038934.6 Chinese utility model patent disclosed " a kind of split type solar vacuum-tube water heater " as the patent No.; Because the diameter of vacuum tube is little, is generally 37～47mm, the U type pipe diameter of interpolation is also corresponding less, so the inner air flow resistance is very big, causes in the heat-exchange system blower fan power consumption very big, and the clear heat of system is relatively low.
The utility model content
The purpose of this utility model is to overcome the shortcoming that prior art exists, and a kind of simple in structure, enforcement convenience is provided, and air flow resistance is little, and power consumption is less, the heat pipe type vacuum pipe solar energy air heat collector that system's clear heat is lower.
The purpose of this utility model is achieved through the following technical solutions: a kind of heat pipe type vacuum pipe solar energy air heat collector, comprise vacuum tube and air sprue, described vacuum tube is inserted in the sprue edge, it is characterized in that: be inserted with heat pipe in the described vacuum tube, the evaporation ends of described heat pipe is in vacuum tube, and the condensation end of heat pipe is arranged in sprue.
Described heat pipe adopts metal material to make; Typical heat pipe is made up of shell, imbibition core (for gravity assisted heat pipe, this part is a vacuum) and end cap, will be pumped into 1.3 * (10 in the pipe
-1～10
-4) fill with an amount of hydraulic fluid after the negative pressure of Pa, make to be sealed after being full of liquid in the imbibition core capillary porous material of being close to inside pipe wall; One end of pipe is evaporator section (bringing-up section), and the other end is condensation segment (cooling section), can arrange the adiabatic section according to application need two sections centres.Liquid carburation by evaporation when an end of heat pipe is heated in the capillary wick, steam flow to the other end and emit heat and condense into liquid under small pressure reduction, liquid flows back to evaporator section along porous material by the effect of capillary force again.So circulation, heat reaches the other end by an end of heat pipe.Heat pipe has comprised following six main processes that are mutually related in the process that realizes this transfer of heat: (1) heat is delivered to (liquid-vapour) interface from thermal source by thermotube wall and the imbibition core that is full of hydraulic fluid; (2) evaporate on liquid (liquid-vapour) interface in evaporator section; (3) steam in the vapor chamber flows to condensation segment from evaporator section; (4) vapour of steam in condensation segment condenses on the liquid interface; (5) heat is passed to low-temperature receiver from (vapour-liquid) interface by imbibition core, liquid and tube wall; (6) make condensed hydraulic fluid be back to evaporator section at the imbibition in-core owing to capillarity.
Described end cap adopts the head formed by spinning structure.
Vacuum tube is inserted in the sprue edge, and adopts the flexible material sealing ring to connect between the sprue, adopts the two seals mode.Adopting with the sealing of sprue inner edge can resistant to elevated temperatures material, and the sealing between the sprue outside can be adopted common temperature-resistant material.Heat pipe can adopt metal washer or ring with being connected of vacuum tube, the material of quoit or ring can be copper or stainless steel and aluminium, and to bear the empty high temperature that shines in the vacuum tube that causes, the interior diameter of packing ring equals the overall diameter of heat pipe, take the mode of interference fit, the thickness of packing ring is between 10～20mm.There is not fit seal between heat pipe and the primary air runner.Sprue will adopt mineral wool or mineral wool to do insulation, and insulation layer thickness is between 50～75mm.
For enhanced heat exchange, improve heat exchange efficiency, can between vacuum tube and intubate, add mental-finned; The thickness of mental-finned is 1～2mm, material aluminium and copper, and length is suitable with vacuum tube length.
Sprue is connected with blower fan.Open blower fan during work, air is taken away the solar irradiation that vacuum tube absorbs by forced convection by the heat pipe condensation end.Heat pipe plays the heat that vacuum tube is absorbed and passes to effect in the sprue.
The utility model has following advantage and effect with respect to prior art: the heat absorbing part of this solar energy air heat collector adopts heat pipe to replace existing U type pipe, resistance in the air heat exchange runner obviously reduces, thereby reduced the work power consumption of blower fan in the heat-exchange system, improved the clear heat of system.Simultaneously, adopt metalwork to be connected between heat pipe and the runner, avoided damage and the runner gas leakage of the high temperature of air heater to hermetic unit, air-tightness is better, and stability in use is better.
