Description

Heat pipe with pliability structure

Technical field

The utility model relates to a kind of heat abstractor, relates in particular to a kind of flexual heat pipe that has.

Background technology

Fast development along with information industry, the data processing speed of computer apparatus is also fast more, when the electronic component of computer apparatus inside is carried out operation, as CPU, the IC element, the power crystal, power supply unit etc., because energising back internal resistance can produce heat, cause component temperature to rise, and the technological progress of integrated circuit and extensive use, drive electronic component towards gently, thin, the direction evolution of little and high-frequency high-speed, the heat that the closeness increase produces unit are also relatively increases, if not having the heat that electronic component is produced discharges in good time, high temperature can cause execution speed to reduce, safety and performance to system can make a big impact, even causing hardware device to damage, the excessive heat energy of accumulation causes temperature to rise when moving in order to suppress electronic component, must use heat abstractor to dispel the heat, and that heat pipe has is super-silent, flash heat transfer, high thermoconductivity, in light weight, size is little, no movable piece, characteristic such as simple in structure is widely used in the electronic element radiating field.

Known heat pipe structure is the sealed tube body that vacuumizes, be provided with capillary structure at the inboard wall of tube body face, body central authorities then are steam channel, and in the body that vacuumizes, inject working fluid, its capacity is equivalent to the hole total measurement (volume) of capillary structure, the characteristic of working fluid is the heat of vaporization height, good fluidity, chemical property is stable, boiling point is lower, as water, ethanol, acetone etc., heat pipe can be divided into evaporator section and condensation segment according to absorbing with the heat function that sheds, when evaporator section is heated, hydraulic fluid in the capillary structure absorbs heat and the temperature rising, when reaching the liquid evaporating point, temperature remains unchanged, still continue to absorb a large amount of heats, make the liquid carburation by evaporation, steam passes through the body internal channel fast under small pressure reduction, steam cooling when arriving condensation segment, when temperature drops to condensation point, temperature remains unchanged, but emit a large amount of heats, heat passes to the external world via heat pipe and distributes, and makes steam condense into liquid to enter capillary structure, and liquid is back to evaporator section under the capillary force effect of capillary structure, circulates with the heat energy that continues phase change and transmits heat.

Known heat pipe is generally straight pipe shape when making moulding, it is in order to thermally coupled pyrotoxin and radiator, the heat that pyrotoxin is produced conducts to radiator and disperses, because pyrotoxin and radiator are arranged at different positions, and the path between pyrotoxin and the radiator still is equiped with other elements, heat pipe must bend to the radian that needs according to the situation of use occasion, dodge other elements or reach the connection purpose, yet, when opposite heat tube carries out buckling work, must the brake forming of straight pipe shape heat pipe could be difficult to directly with the manpower bending, again with apparatus, to carry out the heat pipe of brake forming in advance, when actual installation,, then also must repeat to adjust the angle of bend of heat pipe again with apparatus, trouble if error is arranged, time-consuming and waste of manpower cost.

In view of this, inventor of the present utility model satisfies at above-mentioned prior art, and the spy concentrates on studies and cooperates the utilization of scientific principle, improves as possible and enhanced performance, can propose a kind of the utility model reasonable in design and effective eventually.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of heat pipe with pliability structure, can comply with actual user demand, just can easily it be bent into required form with manpower.

In order to solve the problems of the technologies described above, the technical solution of the utility model is that a kind of heat pipe with pliability structure comprises:

One metal body;

One pliability structure takes shape on this metal body, and this pliability structure mainly is made of most the rings that the space is provided with, and the center of these rings is limited by the axial line of this metal body;

One mesh grid is laid in the inside of this metal body, and this mesh grid is in to forming most bulge loops that amplexiform these rings in pliability structure place;

One working fluid is filled in the inside of this metal body and is attached in this mesh grid; And

One support component is arranged in the inside of this mesh grid, this support component push against this mesh grid towards and amplexiform the inwall of this metal body.

The beneficial effects of the utility model are, the pliability shaping structures is on the metal body, make heat pipe must be crooked according to the actual assembled situation time, can directly not need to use apparatus with the manpower bending forming, make ease of assembly and save man-hour, and mesh grid and support component are crooked and crooked with heat pipe, can not rupture because of bending, the state that makes the inwall of mesh grid maintenance and metal body amplexiform, and working fluid is flowed in mesh grid swimmingly and can not be blocked, to keep the good heat conductive effect.
