Abstract
The utility model relates to an improved duct heater; the duct heater comprises a pipe body, one end of which is provided with a closed end, and the other end is provided with a sealed end; poromeric copper powder is formed and arranged on an internal side wall of the pipe body by sintering; the interior of the pipe body is in a structure of a vacuum state and an operating fluid body is injected into the pipe body. The manufacturing processes are that: firstly arranging one end of the pipe body as closed, and the other end as opened; the copper powder is adhered to the internal side of the pipe body by sintering; secondly after the pipe body is vacuumized, injecting the operating fluid body and sealing the opening end. With the method, the copper powder cooperates with the operating fluid body, utilizing the copper powder to conduct heat on the pipe body rapidly and utilizing the operating fluid body to absorb heat, thus enabling the heat to conduct rapidly on a heat conduction pipe and achieving the superexcellent heat dissipating effect.
Description
Technical field
The utility model relates to the heat pipe in the heat-exchange device of a kind of general heat interchange field, particularly relates to a kind of being installed in the computer equipment, and the heat pipe of excellent radiating effect can be provided.
Background technology
In present employed computer equipment, the narrow and small notebook computer in inner space for example, because computing machine in the running, partly assembly will send high heat, for effectively being run well, computing machine provide the user to continue to use, must utilize various radiating subassemblies to be dispelled the heat, wherein the heat abstractor of thermal conductance tubular type is wherein a kind of.
See also Fig. 4, shown in Figure 5, it is the existing heat pipe construction synoptic diagram of commonly using, it is the employed heat pipe of thermal conductance tubular type heat abstractor, one end of its body (70) is blind end (72), in addition end then be a sealing end (74), this sealing end (74) finish vacuumize after, promptly give the while involution, make the inside of body keep vacuum state, so that use for heat radiation.This existing heat pipe still has the defective that heat can not be conducted fast on this heat pipe, can not reach preferable radiating effect, and truly has further improved necessity in addition.
Because above-mentioned existing heat pipe construction is to the greatest extent insuperior in design, the design people is actively studied innovation, through constantly studying, designing based on abundant practical experience and professional knowledge, and through repetition test and after improving, development finally creates the utility model that has practical value.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcome the defective that existing heat pipe exists, and provide a kind of structure improved heat pipe, its body inboard at heat pipe is adhered in the mode of sintering be provided with copper powder, then body is vacuumized and in body, sealed behind the injection working fluid.By this, can utilize cooperating of copper powder and working fluid, heat can be conducted on this heat pipe fast, and can reach excellent radiating effect.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to a kind of heat pipe that the utility model proposes, it is characterized in that this heat pipe construction includes: a body, the one end forms and is provided with blind end, the other end then forms and is provided with sealing end, sintering forms and is provided with porous copper powder on the madial wall of this body, and within the body for being the vacuum state structure, and in this body, inject and be provided with working fluid.
The utility model compared with prior art has tangible advantage and beneficial effect.By above technical scheme as can be known, the heat pipe of the utility model improvement, one end of its body is a closed, the other end is then opening-like, adhere in the mode of sintering in the body inboard of heat pipe and to be provided with copper powder, then body is vacuumized the back and in body, be injected with working fluid, and openend sealed, by this, can utilize cooperating of copper powder and working fluid, utilize copper powder with heat conduction and absorption heat of working fluid fast on body, and heat can be conducted on this heat pipe fast, and then can reach excellent radiating effect.
In sum, the utility model heat pipe utilizes the copper powder of sintering and cooperating of working fluid, the heat that can conduct computer equipment apace and sent, and with its absorption, and can reach excellent radiating effect, improved the shortcoming that existing this type of heat pipe of commonly using exists effectively, thereby be suitable for practicality more, no matter it structurally or bigger improvement all arranged on the function, and have than much progress technically, and produced handy and practical effect, and have the effect of enhancement really, thereby being suitable for practicality more, really is a new and innovative, progressive, practical new design.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its embodiment of heat pipe, structure, feature and effect thereof according to the new structure that the utility model proposes, describe in detail as after.
See also Fig. 1, shown in Figure 2, the utility model is a kind of heat pipe of new structure, the structure of this heat pipe includes: a body (10), the one end forms and is provided with blind end (14), the other end then forms and is provided with sealing end (12 '), sintering forms and is provided with porous copper powder (30) on the madial wall of body (10), and is the structure of vacuum state within the body (10), and injection is provided with working fluid (40) in this body (10).
The manufacturing process of this heat pipe is: at first need prepare a body made of copper (10), this body (10) is provided with an openend (12) and a blind end (14), then insert a bronze medal post (20) by this openend (12), and in body (10), be equipped with copper powder (30), then in the mode of sintering, after copper powder being attached to the medial surface of body (10), extract copper post (20) out.Body this moment (10) will form a mesopore (35), and formation is provided with the poriness copper powder (30) that sintering is finished around this mesopore (35), then in this body (10), inject and be provided with working fluid (40), and the openend (12) of body is sealed and forms sealing end (12 '), i.e. formation heat pipe one-piece construction as shown in Figure 2.
See also Fig. 2, shown in Figure 3, during generating component in heat pipe is posted by computing machine, the heat that it produced will make the local temperature of heat pipe rise, and make that therefore the in one's duty working fluid of this flashes to gas after absorbing a large amount of heats, and this gas flow is to the lower position of heat pipe temperature, with condensation and discharge entrained heat, then by capillary action, condensed working fluid will be recycled to the higher part of temperature in the heat pipe through porous copper powder (30), and repeat once aforesaid Evaporation Phenomenon and form a thermal cycle, thereby can be quick, effectively heat radiation.Working fluid (40) is not filled with fully within body (10) owing to heat pipe of the present utility model again, and can be avoided working fluid (40), and heat pipe is produced adverse influence because of the temperature variation rising-heat contracting-cold.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
