Zusammenfassung:According to the present invention, a method for injecting and sealing a heating medium of a flat plate heat spreader includes the steps of: preparing a flat plate heat spreader with multiple internal channels formed thereon to have both sides open while being formed at predetermined intervals with each other; fixing the heat spreader in a vertical position to arrange both sides of each internal channel of the heat spreader in upward and downward directions; injecting a liquid heating medium of T1 into the individual internal channels at the same time through the upper parts of the heat spreader fixed in a vertical position; heat-pressing and compressing the lower parts of the heat spreader after the elapse of time t1 from the point of injecting the liquid heating medium to the individual internal channels as T2(>T1); and heat-pressing and compressing the upper parts of the heat spreader as T2 to seal the upper parts after the elapse of time t2 from the point of heat-pressing and compressing the lower parts of the heat spreader. The method can be used to seal both ends of a heat spreader after injecting a refrigerant to each internal channel at the room temperature and under the atmospheric pressure without needing a separate facility. 본 발명은, 상호 간에 일정간격 이격되어 형성되되 각각의 양측 부위가 개구된 복수 개의 내부채널이 마련된 평판 히트 스트레더를 준비하는 단계; 히트 스프레더의 각 내부채널 양측 부위가 상하로 위치하도록 히트 스프레더를 수직 상태로 고정하는 단계; 수직 상태로 고정된 히트 스프레더의 상측 부위를 통해 T1의 액상 열매체를 각 내부채널에 동시 주입하는 단계; 각 내부채널에 액상의 열매체를 주입한 시점으로부터 △t1 시간 이후에 히트 스프레더의 하측 부위를 T2(〉T1)로서 열간 압착하여 밀봉하는 단계; 히트 스프레더의 하측 부위를 열간 압착한 시점으로부터 △t2 시간 이후에 히트 스프레더의 상측 부위를 T2로서 열간 압착하여 밀봉하는 단계;를 포함하여 이루어지는 평판 히트 스프레더의 열매체 주입 및 밀봉 방법을 제공한다.
