Abstract: A heat exchanger according to the present invention comprises: a plate-shaped body having an interior space in which a working fluid is vaporized or condensed and flows; and a wick located within the body, the wick comprising a plurality of needle-shaped particles between which the working fluid flows. By forming a wick comprising needle-shaped particles, the heat exchanger according to the embodiments of the present invention can improve the porosity of the wick compared to conventional groove or mesh-shaped or sintered wicks. Accordingly, the working fluid is capable of flowing inside the wick more smoothly than in the conventional wicks, thereby improving a heat exchange rate or heat exchange performance.

Abstract translation: 根据本发明的热交换器包括：具有内部空间的板状体，工作流体被蒸发或冷凝并流动; 以及位于所述主体内的芯，所述芯包括多个针状颗粒，所述工作流体在其间流动。 通过形成包括针状颗粒的芯，根据本发明的实施例的热交换器可以改善与常规凹槽或网状或烧结芯相比的芯的孔隙率。 因此，工作流体能够比常规芯子更顺利地流动芯体内，从而提高热交换率或热交换性能。
