Phase change heat exchanger and heat exchange core thereof

The phase change heat exchanger comprises an evaporator and a condenser which is communicated with the evaporator and located above the evaporator, and at least one of the evaporator and the condenser is obliquely arranged in a machine shell. In the practical application process of the heat exchange core, at least one of the evaporator and the condenser is obliquely arranged in the machine shell, so that the space in the thickness direction of the inner cavity of the shell of the phase change heat exchanger can be fully utilized, the span in the connecting direction of the evaporator and the condenser can be reduced, and the overall size of the phase change heat exchanger can be reduced. 本发明公开了一种相变换热器及其换热芯体，包括蒸发器和与蒸发器连通且位于蒸发器上方的冷凝器，蒸发器和冷凝器这两者中的至少一者在机壳内呈倾斜布置。该换热芯体，实际应用过程中，由于蒸发器和冷凝器这两者中的至少一者在机壳内呈倾斜布置，因此，能够充分利用相变换热器的壳体内腔的厚度方向的空间，降低蒸发器与冷凝器连接方向的跨度，继而有助于缩减相变换热器的整体体积。
