The invention relates to a heat exchanger, a vehicle air conditioner heat exchange system and a vehicle. The heat exchanger comprises a heat exchange shell and a guide structure. A heat exchange channel for heat exchange media to circulate is formed in the heat exchange shell. The heat exchange channel comprises an inlet end and an outlet end. The guide structure is arranged in the heat exchange channel, and the guide structure is configured in the mode that the flow resistance of the heat exchange medium flowing in the forward direction is larger than the flow resistance of the heat exchange medium flowing in the reverse direction. Wherein the forward flow means that the heat exchange medium flows from the inlet end to the outlet end, and the reverse flow means that the heat exchange medium flows from the outlet end to the inlet end. When the heat exchanger is used as a condenser for heating, a heat exchange medium can pass through the guide structure, and the flowing speed of the heat exchange medium during forward flowing is reduced, so that the heat exchange medium can fully exchange heat in the heat exchanger; therefore, the heat exchange performance of the heat exchanger can be balanced when the heat exchanger is used as an evaporator for refrigeration or used as a condenser for heating during heat exchange.

    本公开涉及一种换热器、车辆空调换热系统以及车辆。换热器包括换热壳体和导向结构。换热壳体内部形成有用于供换热介质流通的换热通道。换热通道包括进口端和出口端。导向结构设于换热通道内,导向结构配置为在换热介质正向流动时的流动阻力大于逆向流动时的流动阻力。其中,正向流动为换热介质由进口端朝向出口端流动,逆向流动为换热介质由出口端朝向进口端流动。在该换热器作为冷凝器制热使用时,换热介质能够通过该导向结构,降低自身正向流动时的流动速度,以使得该换热介质能够在换热器内充分进行换热,从而保证该换热器无论是作为蒸发器制冷使用还是作为冷凝器制热使用时的换热时换热性能能够较为均衡。
