Abstract

The utility model discloses a conjoined needling type plane heat pipe radiating device, belonging to a radiating device for electronic components, which consists of a copper heat conducting base used for hanging to the radiating components and carrying off the heat quantity by means of thermal conduction. A plurality of fins formed by conjoined cutting spread over the base. The utility model has the advantages of minimum dissipation of thermal conduction, big radiating area and good radiating effects.

Description

Disjunctor aculeus type plane heat-pipe radiating apparatus

One, technical field

The utility model relates to the heat abstractor of electronic devices and components, makes the field especially for the air-cooled heat abstractor of integrated circuit modules.

Two, background technology

Along with the develop rapidly of electronic technology, the integrated degree of circuit is more and more higher.Therefore, the heat dissipation problem of the chip of ultralarge scale integration presses for and is properly settled.For example, for the cpu chip of computer, generally adopt the aluminium section bar fin to add fan now and dispel the heat.Its CPU is close to the bottom of metal fin, fan is placed the fin top again, utilizes electric fan to rotate, and makes the air of fin top produce mobile.This radiating mode utilizes heat exchange pattern on the one hand, makes metal fin directly remove heat from chip, utilizes the cross-ventilation mode on the other hand, takes away the heat in the metal fin.The heat radiation requirement of the chip that the integrated degree that this conventional fan radiating mode can not satisfy improves day by day.Communication system and for example, function is more and more, and data transmit more and more faster, and digital just more and more huger, it is more and more higher consume energy, and the heat that is produced is just very huge, and heat can not leave rapidly, and thermal accumlation gets up, and will burn out machine.SAM system supposes to control simultaneously originally three pieces of guided missiles for another example, now controls 6 pieces of guided missiles simultaneously, and numeral doubles at least, and power consumption is doubled at least, if heat does not leave rapidly, machine will soon hotly get and can't work, even burns out system.And in the ordinary course of things, the staff is difficult to timely discovery, so that shut down heat radiation.Therefore, heat radiation becomes the formidable enemy of various high-tech, military production development.

Three, utility model content

The purpose of this utility model is to provide a kind of disjunctor aculeus type plane heat-pipe radiating apparatus at prior art problems, and it has better radiating effect.The purpose of this utility model is realized by following design: a kind of disjunctor aculeus type plane heat-pipe radiating apparatus, comprise and be used to be close to the fin of its heat being taken away by heat dissipation element, by heat exchange pattern, it is characterized in that, described fin is copper heat conducting base, and heat conducting base is provided with the numerous fins that form through the disjunctor cutting way.

Above-mentioned heat conducting base adopts pure red copper to make.

In the above-mentioned design, particularly on the heat conducting base of pure red copper fin is set at copper material, and, fin and pedestal are Contiuum types, from heat conductivility, the setting of fin has greatly increased area of dissipation, accelerated radiating rate, strengthened radiating effect, the Contiuum type fin has reduced heat conducting resistance between fin and the pedestal effectively, the alternate manner that is provided with fin as, welding, riveted joint, crimping are compared, the capacity of heat transmission of material is not subjected to loss, does not give a discount, has brought into play fully, makes its radiating effect splendid.This novel employing hot pipe technique adds copper disjunctor fin and dispels the heat, and on heat sink material and heat exchange pattern, is better than conventional aluminum section bar heat abstractor greatly.

Four, description of drawings

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the stereogram of Fig. 1.

Five, embodiment

Fig. 1 Fig. 2 Fig. 3 illustrates, heat conducting base 2 adopts copper material, preferably pure red copper, fin 1 forms by the disjunctor cutting way, and it spreads all over and is arranged on the heat conducting base, and each fin size shape is basic identical, its shape can be that strip (is shaped as rectangle in the front view, thickness remains unchanged from top to bottom), fin shape also can be an isosceles trapezoid (from front view), thickness remains unchanged from top to bottom.Offer inner chamber 3 in the heat conducting base, be loaded with heat-conducting work medium 5 in the inner chamber, as acetone etc., inner chamber be provided with as extracting vacuum vacuumize mouth 4, heat-conducting work medium 5 tops are vacuum condition in the inner chamber.Heat conducting base 2 is provided with otic placode, have on the otic placode fixing with screw 6, use when installing and fixing.

During use, will be close to the heat conducting base lower surface, the heat of element be taken away, can pass through fan again, remove heat on the fin in the cross-ventilation mode with heat exchange pattern by heat dissipation element 7.The heat that heater during work (by heat dissipation element 7) produces conducts heated portion to plane heat pipe (heat conducting base 2 that inner chamber is arranged) by heat conducting base, then be sent to the liquid refrigerant of heat conduction, make its heating vaporization evaporation, the heat that heated portion is accepted reaches that gather and the radiating fin substrate disjunctor on the substrate, carry out heat exchange by radiating fin and air, make steam liquefaction in the heat pipe and be back to heated portion, the heat that radiating fin distributes is discharged outside the machine rapidly by air (fan), reach heat balance, heater element is in the normal operating temperature range for a long time.

This novel easy to install, stable work in work, heat conduction losses is minimum, and area of dissipation is big, and radiating effect is splendid.
