Description
Technical field
The present invention relates to a kind of solar heat pipe, a kind of specifically transverse internal thread heat pipe of solar water heater.
Background technology
At present, using solar heat pipe on the market mainly is that thermal siphon also is gravity assisted heat pipe.There is not the imbibition core in the thermal siphon pipe, working medium turns back to evaporator section from condensation segment, and what lean on is the gravity of working medium self, so the work of thermal siphon has certain directionality, evaporator section must place the below of condensation segment, so just can make working medium lean on the gravity of self to be turned back to evaporator section.The mounting means that this has also just determined heat pipe has limited the use of heat pipe, and use is caused limitation.The Horizontal heat pipe that has occurred on the present market, overcome the circumscribed problem of installation of thermal siphon, but because it increases filling amount or single, simple capillary structure, cause heat-pipe working medium backflow resistance big or can not in time reflux, make heat pipe not conduct heat continuously or inefficiency, can not demand.
Summary of the invention
Technical problem to be solved by this invention is: the shortcoming at above prior art exists, a kind of transverse internal thread heat pipe of solar water heater is proposed, and can level install, high efficiency, be applicable to remotely transferring under low-angle or the horizontal state.
The technical scheme that the present invention solves above technical problem is:
Transverse internal thread heat pipe of solar water heater comprises evaporator section, condensation segment and adiabatic section, and there is working medium the adiabatic section in the heat pipe package between evaporator section and condensation segment, the heat pipe package inwall be provided with screw thread or/and the straight line conduit or/and silk screen.
On the heat pipe package inwall, screw thread, straight line conduit and silk screen have multiple assembled scheme, can be that the heat pipe package inwall is a helicitic texture; The straight line conduit is arranged on the heat pipe inwall; Be furnished with silk screen on the heat pipe inwall; The heat pipe inwall is an internal thread, and arranges silk screen; The heat pipe inwall has the straight line conduit, and arranges silk screen; The heat pipe inwall is an internal thread, and has drawn the straight line conduit, and arranges silk screen.
Heat pipe package is metal or the materials compatible with working medium such as copper, silver, aluminium, carbon steel, stainless steel.Screw thread is evenly distributed on the tube wall, and the angle β of thread and tubular axis is 0 °～44 °, and the screw thread tooth depth is 5%～70% of a pipe thickness.Silk screen applying thermotube wall, with shell be concentric.The order number of silk screen is 100 orders～500 orders.Heat pipe package, silk screen and working medium are compatible.
Advantage of the present invention is: have screw thread, straight line conduit and silk screen on the heat pipe package inwall of the present invention, working medium is arranged in the heat pipe package, this shell internal structure, the resistance that fluid refluxes when having reduced heat pipe work, strengthened heat pipe remote heat exchange effect under low-angle or horizontal state, improved Heat Transfer of Heat Pipe on Heat Pipe efficient, overcome existing heat pipe under low-angle or horizontal state during remotely transferring power low, monistic defective is installed, satisfied the requirement of high power transmission.

The specific embodiment
Embodiment one
The structure of this enforcement as shown in Figure 1, transverse internal thread heat pipe of solar water heater comprises evaporator section, condensation segment and adiabatic section, and the adiabatic section is between evaporator section and condensation segment, working medium is arranged in the heat pipe package, and the heat pipe package inwall is provided with screw thread 11/ and straight line conduit 12/ and silk screen 13
On the heat pipe package inwall, screw thread 11, straight line conduit 12 and silk screen 13 have multiple assembled scheme, can be that the heat pipe package inwall is a helicitic texture 11; Straight line conduit 12 is arranged on the heat pipe inwall; Be furnished with silk screen 13 on the heat pipe inwall; The heat pipe inwall is an internal thread 11, and arranges silk screen 13; The heat pipe inwall has straight line conduit 12, and arranges silk screen 13; The heat pipe inwall is an internal thread 11, and has drawn straight line conduit 12, and arranges silk screen 13.
Heat pipe package is metal or the materials compatible with working medium such as copper, silver, aluminium, carbon steel, stainless steel.Screw thread 11 is evenly distributed on the tube wall, and the angle β of screw thread 11 teeth and tubular axis is 0 °～44 °, and screw thread 11 tooth depths are 5%～70% of pipe thickness.Silk screen 13 applying thermotube walls, with shell be concentric.The order number of silk screen 13 is 100 orders～500 orders.Heat pipe package, silk screen 13 are compatible with working medium.
Fig. 2, Fig. 3, Fig. 4 and Fig. 5 are general heat pipe and operation principle comparison diagram of the present invention, and the operation principle of heat pipe all is that the heat that will obtain from thermal source is delivered to liquid-vapour interface 1 by thermotube wall and the internal structure that is full of working medium 2; 1 evaporation on the liquid-vapour interface of working medium 2 in evaporator section 3 (bringing-up section); Steam in the vapor chamber flows to condensation segment 4 from evaporator section 3; 6 condense on the vapour-liquid interface of steam in condensation segment 4; Heat is passed to low-temperature receiver from vapour-liquid interface 6 by internal structure, working medium 2 and tube wall; In imbibition in-core portion structure, make condensed working medium 2 be back to evaporator section 3 owing to capillarity.But the work of the heat pipe of prior art has certain directionality and the work of transverse internal thread heat pipe of solar water heater does not have directionality, its inner working media 2 is when work, do not need to rely on the gravity effect of working medium 2 self, but the capillary force that the structure of leaning on inside heat pipe internal thread 8 and straight line conduit 7 causes, drive the working medium 2 periodic duty, finish the process of Heat Transfer of Heat Pipe on Heat Pipe.
The present invention can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the scope of protection of present invention.
