The invention discloses a heat dissipation device, and relates to the technical field of heat exchange devices. The heat dissipation device comprises a refrigeration plate and a parallel flow heat exchanger, the first side of the refrigeration plate is arranged on the heating device, and a refrigeration working medium loaded in the refrigeration plate absorbs heat generated by the heating device and is vaporized; the parallel flow heat exchanger mounted above the refrigeration plate is provided with a heat exchange inlet and a heat exchange outlet which are communicated with the interior of the refrigeration plate, and the heat exchange outlet is lower than the heat exchange inlet, so that a vaporized refrigeration working medium enters the parallel flow heat exchanger from the heat exchange inlet to release heat and be liquefied; and the liquefied refrigeration working medium flows back to the refrigeration plate from the heat exchange outlet under the action of gravity. According to the heat dissipation device, the refrigeration working medium serves as a heat exchange medium, and the heat dissipation performance of the heat dissipation device is better; the refrigerant only depends on gravity to serve as circulating power, and the size of the heat dissipation device is smaller; interference of dust, corrosive gas, moisture and the like on the heating device is reduced, and the working performance of the heating device is more stable.

    本申请公开了一种散热装置,涉及热交换装置技术领域;散热装置包括制冷板和平行流换热器,制冷板的第一侧设置在发热器件上,制冷板内部装载的制冷工质吸收发热器件产生的热量并汽化;安装在制冷板上方的平行流换热器设置有与制冷板的内部连通的换热进口和换热出口,并且换热出口低于换热进口,以实现汽化的制冷工质从换热进口进入平行流换热器放热并液化,液化的制冷工质在重力的作用下从换热出口流回制冷板。上述散热装置以制冷工质作为换热介质,散热装置的散热性能更好;制冷工质仅靠重力作为循环动力,散热装置的体积更小;减轻了尘埃、腐蚀性气体、湿气等对发热器件造成的干扰,发热器件的工作性能更稳定。
