Description
Technical field
The utility model relates to a kind of heat pipe, is specifically related to a kind of liquid-sucking core of heat pipe, belongs to hot pipe technique field.
Background technology
Heat pipe is a kind of novel, efficient heat conducting element, and heat pipe is the element of a closed dependence Working fluid phase changing heat transfer, forms primarily of metal sealing pipe, liquid-sucking core and steam channel part.By on-condensible gas removing in metal tube, be pumped into negative pressure, inside pipe wall is attached with capillary porous material and does liquid-sucking core, seals this metal tube and then made a heat pipe after being filled with working medium.Heat pipe is divided into evaporator section, adiabatic section and condensation segment vertically.Heat pipe has high, the excellent thermal conductivity of heat flux and good isothermal, be widely used in Aero-Space, electronic device and chemical field, but, radiating condition high in some heat dissipation capacities requires in high applied environment, there is the problem that fluid transport resistance is large, circulation is little in existing heat pipe, and liquid-sucking core is the critical component affecting heat pipe operating efficiency.
For this reason, designer of the present utility model is because above-mentioned technological deficiency, and by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of liquid-sucking core of heat pipe, to overcome above-mentioned technological deficiency.
Utility model content
The technical problems to be solved in the utility model is: the liquid-sucking core providing a kind of heat pipe, and to solve, heat pipe transport resistance in prior art is large, the little technical problem that can not meet the applied environment that heat dissipation capacity is high, radiating condition requirement is high of circulation.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of liquid-sucking core of heat pipe, described heat pipe comprises cylindrical shell and liquid-sucking core, liquid-sucking core is installed on enclosure interior, it is characterized in that: liquid-sucking core comprises the upper bracing ring be arranged in tube body of heat pipe, lower support circle and bonding jumper, some bonding jumpers are fixedly connected between bracing ring and lower support circle, and some bonding jumpers are uniformly distributed at the circumferencial direction of upper bracing ring and lower support circle, described bonding jumper is the shape of cross section of porous metal foam processing is the bonding jumper of Ω type, gap between adjacent bonding jumper and Ω type runner form the conduit of liquid-sucking core jointly, 2 ~ 3 brackets for reinforcing also are set between upper bracing ring and lower support circle, on bracket, lower end is fixedly connected on bracing ring and lower support circle respectively.
Bonding jumper and the mode that is fixedly connected with between upper bracing ring and lower support circle are for weld or screw is connected.
The liquid-sucking core of a kind of heat pipe of the present utility model, have employed gap and Ω type runner between bonding jumper to combine the common conduit forming liquid-sucking core, and choose the material of foam metal as bonding jumper, improve effective capillary radius, porosity, permeability, the effective thermal conductivity of liquid-sucking core, reduce fluid transport resistance, fluid flowing is smooth and easy, and heat flux is large, diabatic process can be substantially improved, enhance heat transfer, improve the heat transfer property of heat pipe.
Detailed content of the present utility model obtains by following detailed description and Figure of description.

In figure: 1 be upper bracing ring, 2 be lower support circle, 3 be bonding jumper, 4 for bracket.
Detailed description of the invention
The liquid-sucking core of a kind of heat pipe of the present utility model is described in detail below in conjunction with Figure of description.
See Fig. 1 and Fig. 2, show the liquid-sucking core of a kind of heat pipe of the present utility model.
A kind of liquid-sucking core of heat pipe, described heat pipe comprises cylindrical shell and liquid-sucking core, liquid-sucking core is installed on enclosure interior, it is characterized in that: liquid-sucking core comprises the upper bracing ring 1 be arranged in tube body of heat pipe, lower support circle 2 and bonding jumper 3, some bonding jumpers are fixedly connected between bracing ring 1 and lower support circle 2, and some bonding jumpers 3 are uniformly distributed at the circumferencial direction of upper bracing ring 1 and lower support circle 2, described bonding jumper 3 for shape of cross section that porous metal foam is processed be the bonding jumper of Ω type, gap between adjacent bonding jumper 3 and Ω type runner form the conduit of liquid-sucking core jointly, 3 brackets 4 for reinforcing also are set between upper bracing ring 1 and lower support circle 2, on bracket 4, lower end is fixedly connected on bracing ring 1 and lower support circle 2 respectively.
Bonding jumper and the mode that is fixedly connected with between upper bracing ring and lower support circle are for weld or screw is connected.
The liquid-sucking core of a kind of heat pipe of the present utility model, have employed gap and Ω type runner between bonding jumper to combine the common conduit forming liquid-sucking core, and choose the material of foam metal as bonding jumper, improve effective capillary radius, porosity, permeability, the effective thermal conductivity of liquid-sucking core, substantially increase the heat transfer property of heat pipe.The setting of bracket adds the mechanical strength of liquid-sucking core.
It is evident that, above description and record be only citing instead of in order to limit content disclosed in the utility model, application or use.Although described in an embodiment and described embodiment with reference to the accompanying drawings, but the utility model do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment of description and the appended claim fallen into above.
