Background technology:
The back arrangement drying and forewarm of denim is commonly used to heat pipe, heat pipe is the very high heat transfer element of a kind of heat transference efficiency, the character that its utilizes heat conduction and refrigerant Rapid Thermal to transmit is delivered to object beyond the thermal source rapidly with the heat of thermal objects, and its capacity of heat transmission surpasses any known metal.The character of fluid working substance is determining the heat conductivility of heat pipe in the body, and the working medium that circulates in the body of existing heat pipe mainly is that boiling point such as water is low, the liquid of easy volatilization.Heat pipe is the heat conducting element that dependence self internal work fluid phase transformation realizes heat conduction, and it has good characteristics such as high-termal conductivity, good isothermal, and good heat conduction effect is widely used in weaving.
Typical heat pipe by end cap, shell, imbibition core and be sealed in the pipe in working fluid form.The active section of heat pipe can be divided into evaporator section, adiabatic section and condensation segment three parts.The making of heat pipe is filled with suitable working fluid after being evacuated in the pipe earlier usually, makes to be sealed after being full of working fluid in the capillary wick of being close to the heat pipe package inwall.One end of heat pipe is evaporator section (bringing-up section), and the other end is condensation segment (cooling section), can arrange the adiabatic section between evaporator section and condensation segment according to application need.Working fluid evaporation gasification forms steam in the capillary wick when heat pipe evaporator section is heated, steam is flowed to the condensation segment of heat pipe by tube chamber under the effect of slight pressure difference, condense into working fluid and emit heat, working fluid again by capillary wick the capillary force effect that is produced that combines with liquid flow back to evaporator section along capillary wick.So circulation, heat constantly reaches condensation segment by the evaporator section of heat pipe, and the low-temperature receiver of the Duan Yiduan that is condensed absorbs.In the conduction process of heat pipe, capillary wick has played key effect.It not only is related to the speed of working fluid at the evaporator section evaporative phase-change with the contact area in the interior space of heat pipe, also is related to the condensation phase velocity of working fluid at condensation segment.Contact area increases the phase velocity that can quicken at evaporator section and condensation segment.
The utility model content:
The purpose of this utility model provides a kind of weaving binary channels formula heat pipe, it can increase the capillary wick of evaporator section and condensation segment and the contact area in the interior space of heat pipe, can also improve the capillarity of heat pipe integral body greatly, and then improve the back-flow velocity of working fluid from the condensation segment to the evaporator section, the heat transfer efficiency of heat pipe is improved.。
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is by shell 1, end cover 4, capillary wick 2, center capillary wick 3 is formed, end cover 4 is arranged on the two ends of heat pipe package 1, capillary wick 2 is close on shell 1 inwall, center capillary wick 3 is arranged on the heat pipe package axial centre cross section, center capillary wick 3 is divided into two passages in both sides with tube chamber, center capillary wick 3 is close at the two ends and the end cover 4 of heat pipe package 1, the both sides of center capillary wick 3 are close to the inboard of capillary wick 2, and have several connected entrances 5 in the junction.Working fluid has been full of capillary wick 2.Heat pipe provided by the utility model has following advantage: on the basis of existing heat pipe structure, the utility model has added center capillary wick 3 in the middle of the body again, and this capillary wick is provided with connected entrance 5 in order to be communicated with two passages with capillary wick 2 junctions on being close to inner wall of tube shell.The center capillary wick 3 that newly adds not only can increase the capillary wick of evaporator section and condensation segment and the contact area in the interior space of heat pipe, can also improve the capillarity of heat pipe integral body greatly, and then improve the back-flow velocity of working fluid from the condensation segment to the evaporator section, the heat transfer efficiency of heat pipe is improved.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment is by the following technical solutions: it is by shell 1, end cover 4, capillary wick 2, center capillary wick 3 is formed, end cover 4 is arranged on the two ends of heat pipe package 1, capillary wick 2 is close on shell 1 inwall, center capillary wick 3 is arranged on the heat pipe package axial centre cross section, center capillary wick 3 is divided into two passages in both sides with tube chamber, center capillary wick 3 is close at the two ends and the end cover 4 of heat pipe package 1, the both sides of center capillary wick 3 are close to the inboard of capillary wick 2, and have several connected entrances 5 in the junction.Working fluid has been full of capillary wick 2.Heat pipe provided in the present embodiment has following advantage: on the basis of existing heat pipe structure, this specific embodiment has added center capillary wick 3 in the middle of the body again, and this capillary wick is provided with connected entrance 5 in order to be communicated with two passages with capillary wick 2 junctions on being close to inner wall of tube shell.The center capillary wick 3 that newly adds not only can increase the capillary wick of evaporator section and condensation segment and the contact area in the interior space of heat pipe, can also improve the capillarity of heat pipe integral body greatly, and then improve the back-flow velocity of working fluid from the condensation segment to the evaporator section, the heat transfer efficiency of heat pipe is improved.
The dual-side that described capillary wick 2 is connected with center capillary wick 3 respectively has four connected entrances 5, and the cross sectional shape of connected entrance 5 is a rectangle.
Present embodiment heat pipe package 1 material adopts copper to be shaped to cylindrical tube, and caliber is 5 millimeters, long 60 millimeters.Capillary wick 2 and center capillary wick 3 are formed by the copper powders may sintering, when heat pipe evaporator section is heated, in the capillary wick 2 and 3 kind working fluid simultaneously carburation by evaporation form steam and enter into steam is flowed to heat pipe by the passage on capillary wick 3 both sides under the pressure differential effect condensation segment, steam is emitted heat after condensing into working fluid, and working fluid flows back to evaporator section by the capillarity of capillary wick 2 and capillary wick 3 again.Heat pipe can adopt liquid such as pure water, ammoniacal liquor, methyl alcohol, acetone or heptane as working fluid, also can in liquid, add the particulate of Heat Conduction Material, as copper powder, nano material etc., to increase the heat conductivility of working fluid, this specific embodiment adopts pure water as working fluid.This specific embodiment is owing to having added center capillary wick 3, no matter heat pipe is at evaporator section or the contact area in space all increases in condensation segment capillary wick and body.This just makes that the working fluid on the capillary wick can more promptly enter into the heat pipe space when heat pipe evaporator section is heated.And after working fluid steam entered into condensation segment, it is big that the speed from steam phase transforming to liquid working fluid also can become.On the other hand, the adding of center capillary wick 3 makes the capillary effect of heat pipe integral body strengthen, thereby flow back into the speed increase of evaporator section at the condensed working fluid of condensation segment.Therefore, the adding of center capillary wick 3 makes the heat exchange efficiency of heat pipe improve greatly.
