Description

플라즈마 열용사 코팅된 히트파이프 윅Plasma Thermal Spray Coated Heatpipe Wick

본 발명은 히트파이프에 관한 것으로서, 더욱 구체적으로는 히트파이프내의 윅 구조를 개선하여 작동유체의 순환효율을 증대시켜 히트파이프의 성능을 향상시킬 수 있도록 플라즈마 열용사에 의한 구리분말이 부착된 구리판을 사용한 플라즈마 열용사 코팅된 히트파이프 윅에 관한 것이다.The present invention relates to a heat pipe, and more specifically, to improve the wick structure in the heat pipe to increase the circulation efficiency of the working fluid to improve the performance of the heat pipe copper plate with copper powder by plasma thermal spraying A plasma heat-spray coated heat pipe wick used.

히트파이프는 작동유체의 증발 잠열을 이용하여 작은 온도차에서도 무동력으로 열을 매우 빠른 속도로 이송하는 장치이다.Heat pipe is a device that transfers heat at very high speed with no power even at small temperature difference by using latent heat of evaporation of working fluid.

도 1은 이러한 히트파이프의 작동 원리를 나타낸 것으로서 도시된 바와 같이, 히트파이프는 진공상태의 파이프(10) 내부에 증류수와 같은 매우 작은 량의 열전달 매체(작동유체)를 주입하고 봉인한 것으로, 크게 증발부(20), 단열이송부(30), 응축부(40)로 나누어진다.1 shows the operating principle of such a heat pipe, as shown in FIG. 1, a heat pipe is injected and sealed with a very small amount of a heat transfer medium (working fluid) such as distilled water into a vacuum pipe 10. Evaporator 20, adiabatic transfer unit 30, the condensation unit 40 is divided.

작동원리를 살펴보면 열원이 위치하고 있는 증발부(20)에서 열을 흡수한 작동유체는 증기 상태로 파이프(10) 내부에 확산하여, 단열이송부(30)를 지나 응축부(40)에서 열을 방출하고 작동유체는 응축된 후 액체로 되어 파이프(10)의 윅(50) 벽면을 타고 증발부(20)로 귀환한다.Looking at the principle of operation, the working fluid absorbed heat from the evaporator 20 is located in the heat source is diffused into the pipe 10 in the vapor state, passing through the heat transfer unit 30 to discharge heat from the condensation unit 40 After the working fluid is condensed and becomes a liquid, the working fluid is returned to the evaporator 20 through the wall of the wick 50 of the pipe 10.

그리고 다시 열을 받아 증발하는 작동을 연속적으로 반복하므로서 열을 이송하는 것이다.Then, the heat is transferred by continuously receiving the heat again and evaporating.

증발부(20)와 단열이송부(30)는 같은 온도를 가지며 응축부(40)보다는 온도가 높다. 또한 각 부분에서의 증기압은 포화 상태가 되며, 증기압의 관계는 증발부(20)와 단열이송부(30)는 같은 압력을 가지며, 단열이송부(30)의 압력은 응축부(40)보다 높다.The evaporator 20 and the adiabatic transfer part 30 have the same temperature and have a higher temperature than the condensation part 40. In addition, the vapor pressure in each part is saturated, the relationship between the vapor pressure and the evaporator 20 and the adiabatic transfer unit 30 has the same pressure, the pressure of the adiabatic transfer unit 30 is higher than the condensation unit 40. .

이러한 결과로 증기는 증발부(20)에서 단열이송부(30)를 지나 응축부(40)로 이송된다. 이런 현상은 열 전달 속도가 음속에 가까운 속도이므로 매우 빠르게 일어난다.As a result of this, the steam is transferred from the evaporator 20 to the condensation unit 40 through the adiabatic transfer unit 30. This happens very quickly because the heat transfer rate is close to the speed of sound.

이와 같은 히트파이프에서, 그 성능은 작동유체의 종류 및 주입량, 파이프(10) 내부의 진공상태 및 청결도 등 여러 가지 변수에 영향을 받을 수 있으나, 특히 응축부(40)에서 응축된 액체가 증발부(20)로 잘 귀환할 수 있도록 하는 것이 매우 중요하다.In such a heat pipe, the performance may be affected by various variables such as the type and amount of injection fluid, the vacuum and cleanliness of the pipe 10, and in particular, the liquid condensed in the condenser 40 may be evaporated. It is very important to be able to return well to (20).

이와 같이 파이프(10) 내부의 작동유체의 원활한 순환을 위하여 윅(50)을 인입하거나 내벽에 홈(groove)을 가공하여 모세관력이 생기도록 한다. 윅(50)으로 사용되는 것은 스크린 메쉬(screen mesh), 선재나 스프링 등 윅(50)재료 표면의 가공 및 표면처리없이 히트파이프 내부에 주입하여 사용한다. 또한 내부 벽면의 홈은 기계적 가공이나 다공질 소결 등에 의해 형성된다.In this way, for smooth circulation of the working fluid inside the pipe 10, the wick 50 is introduced or a groove is processed in the inner wall to generate capillary force. Used as the wick 50 is injected into the heat pipe without processing and surface treatment of the surface of the wick 50 material such as screen mesh, wire rod or spring. In addition, the grooves on the inner wall surface are formed by mechanical processing, porous sintering, or the like.

이와 같은 윅에 대한 선행기술로서 열전달특성을 향상시키기 위하여 파이프의 내벽에 금속표면 처리를 하거나 파이프 내벽에 유기 및 무기물질로 표면처리된 금속테이프를 부착함으로서 파이프 중앙으로 증기 통로를 확보하도록 하는 것이 제안되고 있다.As a prior art for the wick, in order to improve heat transfer characteristics, it is proposed to secure a vapor passage in the center of the pipe by attaching a metal surface treated with an organic and inorganic material to the inner wall of the pipe or by attaching a metal tape surface-treated with organic and inorganic materials to the inner wall of the pipe. It is becoming.

또 다른 기술로서 다공질로 소결된 파이프 내벽과 그루브에 의하여 모세관 펌핑력을 증가하고, 원주방향으로 작동유체가 골고루 분배되도록 하거나, 파이프 내에 증기와 액체가 부분적으로 존재하면서 열에 의한 파이프 내부의 증기압 불균형으로 관로를 따라 작동유체가 주기적으로 맥동을 일으키는 현상을 이용하는 방법등 여러 가지 다양한 기술이 알려져 있다.Another technique is to increase the capillary pumping force by the porous sintered pipe inner wall and grooves, to distribute the working fluid evenly in the circumferential direction, or to the unbalanced steam pressure inside the pipe due to the partial presence of steam and liquid in the pipe. Many different techniques are known, including the use of pulsations that periodically cause the working fluid to pulsate along the pipeline.

그러나 상기의 여러 가지 형태의 종래기술은 소형화가 곤란하거나 제조 공정이 매우 까다롭고, 생산원가가 높고 생산성 및 성능이 저하되는 문제점이 있었다.However, the various forms of the prior art have a problem in that miniaturization is difficult or the manufacturing process is very difficult, the production cost is high, and productivity and performance are deteriorated.

이와 같은 문제점을 개선하기 위하여 본 발명에서는 히트 파이프의 제조 공정을 용이하게 하고 충분한 모세관력을 확보함으로서 히트파이프의 성능을 개선, 경쟁력 있는 히트파이프 제품을 생산할 수 있도록 한 플라즈마 열용사 코팅된 히트파이프 윅을 제공하는데 그 목적이 있다.In order to improve the above problems, the present invention facilitates the manufacturing process of the heat pipe and secures sufficient capillary force to improve the performance of the heat pipe, and to produce a competitive heat pipe product. The purpose is to provide.
