Abstract
The gravity heat pipe heat dissipation device comprises a radiator (3), a gravity heat pipe (5) and a working medium (8), wherein the gravity heat pipe (5) is vertically arranged, the radiator (3) is fixed at the upper end of the gravity heat pipe (5), and the working medium (8) is filled in the gravity heat pipe (5). The utility model discloses it is different with ordinary "heat pipe" heat abstractor on the theory of operation, so intraductal wick that does not adorn, simple structure, the conduction thermal efficiency is high, and is with low costs, and noiselessness, and the reliability is high, and is longe-lived, energy-conserving. Is particularly suitable for desktop computers.
Description
The utility model relates to a kind of gravity heat pipe heat abstractor.
Mostly forced-convection heat transfer is to utilize ventilation blower or pump in product at present, orders about working fluid (air or the liquid) heating surface of flowing through, and a kind of cooling means that heat is taken away, its shortcoming is that noise is big, and fault is many, and heat transfer efficiency is low.For example adopt the blower fan heat radiation in computer, the blower fan that CPU uses is often stuck, changes inconvenience.Noise is big, and especially the dead of night's noise is more obvious, increases worry to people.If adopt capillary pump " heat pipe " heat radiation just can overcome above shortcoming, still, its cost especially uses in civilian goods than higher, because the price height does not use in desktop computer so far.
The purpose of this utility model is to design a kind of gravity heat pipe heat abstractor, and not only noiseless, and volume is little, in light weight, simple in structure, cost is low, heat transfer efficiency is high, is particularly suitable for desktop computer and uses.
Design of the present utility model: a kind of gravity heat pipe heat abstractor, comprise radiator (3), working medium (8), gravity heat pipe (5) is vertical to be provided with, and radiator (3) is fixed on the upper end of gravity heat pipe (5), and working medium (8) is filled in the gravity heat pipe (5).
The lower end of gravity heat pipe (5) is provided with catches hot device (4).The middle part of gravity heat pipe (5) is provided with jacket (13).The lower end of gravity heat pipe (5) is provided with the envelope mouth (9) of bleeding.
Operation principle: it is to utilize the hot junction to catch heat, vaporization after working solution (working medium) is heated in the pipe.Owing to produce pressure differential between cold and hot, make steam conduct to cold junction at a high speed by the hot junction.Emit a large amount of latent heats of vaporization after the steam condensation, heat is dispersed in the atmosphere by radiator or natural wind on the heat pipe of sealing.Working solution (working medium) after utilizing gravity with in-tube condensation again flows back to the hot junction along tube wall, and so constantly periodic duty is to reach radiating effect continuously.
Advantage that the utility model compared with prior art has and effect:
1, gravity heat pipe heat abstractor is because it is different with common " heat pipe " heat abstractor on operation principle, so do not adorn the imbibition core in the pipe.Therefore, it simple in structure, and heat-conducting efficiency height, cost are low held susceptible to user acceptancely, has the stronger market competitiveness.
2, noiseless, the reliability height, the life-span is long, and is energy-conservation.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of gravity heat pipe heat abstractor comprises radiator (3), working medium (8), and gravity heat pipe (5) is vertical to be provided with, and radiator (3) is fixed on the upper end of gravity heat pipe (5), and working medium (8) is filled in the gravity heat pipe (5).The lower end of gravity heat pipe (5) is provided with catches hot device (4).The middle part of gravity heat pipe (5) is provided with jacket (13).The lower end of gravity heat pipe (5) is provided with the envelope mouth (9) of bleeding.
According to the thermal source size of product radiator spare, the condition of installation position (volume size) come to be determined the working material in the pipe, select for use acetone, liquid nitrogen, ethanol and distilled water all can, and consider compatibility with tubing.The geometry of heat pipe and size are determined according to the maximal heat transfer amount of heat pipe.By the envelope mouth of bleeding working medium is injected at last, vacuumized rear enclosed.
The hot junction skewer of gravity heat pipe is gone into the position that the product thermal source is concentrated, catching hot device (4) is heated by contacting with chip (6), and then make the interior working medium of gravity heat pipe (5) (8) start vaporizer that is heated, steam zone the latent heat of vaporization and is conducted to cold junction at a high speed, by means of radiator (3) on the gravity heat pipe (5) and natural wind heat radiation, and emit a large amount of latent heats of vaporization, make working medium (8) condensation change into liquid, utilize gravity to flow back to the hot junction, finish a circulation along gravity heat pipe (5) inwall.Periodic duty so continuously is to reach continuous heat radiation ground purpose.The parameter of institute's suction will be according to the watt level of required heat radiation in the gravity heat pipe, the physical parameter of working medium and determining.
Using method: with the heat radiation with gravity heat pipe heat abstractor replaced C PU blower fan radiator in desktop computer is the use installation method that example illustrates it.Cpu chip (6) is fixed on the mainboard (2), take down former blower fan radiator, to catch hot device (4) with original geometrical clamp (7) and be fixed on the cpu chip (6), the vertical gravity heat pipe (5) that inserts in catching hot device (4) utilizes stage clip (12) to adjust to the optimum position vertically then.In order to reduce thermal resistance, add heat-conducting silicone grease catching between hot device (4) and the cpu chip (6), catching same adding heat-conducting silicone grease between hot device (4) and the gravity heat pipe (5) simultaneously.
During computer operation, cpu chip (6) heating, be caught hot device (4) with heat absorption and pass to gravity heat pipe (5) immediately, intraductal working medium (8) is carburation by evaporation immediately, conducting at a high speed cold junction emits a large amount of latent heats of vaporization and is loose in atmosphere by radiator (3) and casing (1), be back to the hot junction along gravity heat pipe (5) inwall after working medium (8) condensation, constantly absorb the heat radiation that circulates of cpu chip heat.
Gravity heat pipe heat abstractor, except easy for installation, and can also adapt to the test of various harsh grades, as: environmental conditions such as impact, vibration, transportation, high temperature, low temperature, high temperature low pressure, low-temperature and low-pressure, protection against the tide, mildew-resistant, can satisfy the employed environmental condition of various products fully through facts have proved.
