Description

Radiating subassembly

Technical field

This creation relates to a kind of radiating subassembly, and espespecially one kind can be greatly decreased outside the effect of production cost and can also possess The radiating subassembly of preferably hot transfer efficiency.

Background technology

Press, with the progress of semiconductor technology, the volume of integrated circuit is also gradually reduced, and in order that integrated circuit can be located Manage the integrated circuit under more data, same volume, it is already possible to accommodate computation modules more than many upper several times than ever, when Execution efficiency more and more higher when computation module quantity in integrated circuit is more and more, thus it is produced during computation module work Heat energy is also increasing, by taking common central processing unit as an example, in the fully loaded workload of height, and the heat that central processing unit gives out Degree, it is sufficient to make central processing unit entirely burn, therefore, the heat abstractor of integrated circuit is turned into important problem.

It is the pyrotoxin in electronic equipment that CPU and chip or other electronic building bricks in electronic equipment are, When electronic equipment is operated, the pyrotoxin will produce heat, therefore existing normal use heat-conductive assembly such as heat pipe, temperature-uniforming plate, flat board There is formula heat pipe etc. good heat radiating and heat conduction efficiency to carry out heat conduction or samming, and wherein heat pipe is mainly making as long-range heat conduction With；It is internal process fluid to be converted into steam state evaporation by liquid by one end absorption heat to transfer heat to heat pipe another End, and then reaches the purpose of heat transfer, and is directed to heat and passes the larger position system of area and can select temperature-uniforming plate as radiating subassembly, Warm plate is mainly by one of contacting with thermal source side plane absorption heat, then to conduct heat to opposite side and make radiating condensation.

However, being the radiating subassembly of single solution due to radiating subassemblies such as known heat pipes and temperature-uniforming plate, speech is changed It, known radiating subassembly is only capable of carrying out heat conduction at the position for heat pipe or temperature-uniforming plate contact thermal source in being arranged at electronic equipment Or the radiating such as samming, and cannot have multiple such as the function of the radiating with samming and long-range heat conduction, certain heat exchange effect Rate is also relatively poor.

The content of the invention

Hence this, is effectively to solve above-mentioned problem, and the main purpose of this creation is to provide one kind production can be greatly decreased The radiating subassembly of cost.

The secondary objective of this creation, is to provide one kind to possess the radiating subassembly of hot transfer efficiency and even temperature effect.

The secondary objective of this creation, is to provide a kind of radiating subassembly with long-range radiating effect.

It is that this creation system provides a kind of radiating subassembly system includes a first noumenon, one second body and up to above-mentioned purpose First and second working fluid, the first noumenon has one first space, and its side projection at least convex body, and the convex body has one Second space is simultaneously connected to have defined a first chamber jointly with first space, and second body has a second chamber, The second body side is connected to a fixed with described convex body one end, and foregoing first chamber is not attached to the second chamber system Logical, first working fluid is filled in the first chamber, and second working fluid is filled in the second chamber, thoroughly The design of this creation is crossed, can not only possess preferably hot transfer efficiency and even temperature effect, be effectively increased outside steam-condensate circulating efficiency, may be used also Production cost is greatly decreased.
