Thewick 23 is attached to the inner surface of thetube 20. - The heat pipe works on a principle of evaporative cooling of the
water 24. The evaporator end 21 absorbs heat from a heat source and transfers the heat to thewater 24. Thewater 24 absorbs the heat and evaporates to form vapor. The vapor flows to the condenser end 22 in a direction of arrows d1, dissipates the heat to cooling components (e.g. fins) and then condenses to form droplets. The condensedwater 24 flows back to theevaporator end 21 in a direction of arrows d2 due to capillary force exerted by thewick 23. Thereby, thewater 24 is circulated in thetube 20 and transfers heat from theevaporator end 21 to thecondenser end 22. - One kind of the conventional heat pipe is made of a high thermal conductivity material such as copper. However, copper has a density of 8.92 grams per cubic centimeter and that results in a relatively heavy weight of the heat pipe. Besides, copper is an expensive metal and thus results in a high cost of the heat pipe. Another kind of the conventional heat pipe is made of a lighter and less costly material such as aluminum. However, aluminum gets corroded when it comes in contact with water over time. Further, aluminum and water react to generate hydrogen gas which gets accumulated inside the heat pipe as a non-condensable gas. This results in a significant loss in performance of the heat pipe. Accordingly, heat pipes with both less weight and manufacturing cost and high performance are needed.
- To overcome the shortcomings, the present invention provides a heat pipe made of composite material to mitigate or obviate the aforementioned problems.
- The main object of the present invention is to provide a heat pipe made of copper and aluminum for high performance and less weight and manufacturing cost.
