The invention provides an outdoor heat exchanger and an electric automobile, and belongs to the technical field of heat exchanger structures. According to the electric automobile, through the design that the first flow channel is composed of the multiple longitudinally-arranged evaporation flat pipes, in the working process that the first flow channel participates in refrigeration, the surfaces of the evaporation flat pipes are frosted, water can be generated when the evaporation flat pipes are defrosted, the water can smoothly fall off from the surfaces of the evaporation flat pipes due to the gravity of the water, and compared with transversely-arranged evaporation flat pipes, the water content is reduced; and defrosting of the surface of the evaporation flat pipe is facilitated. The outdoor heat exchanger comprises a heat exchanger body. The heat exchanger body comprises a first flow channel and a second flow channel. A drainage device is mounted between the first flow channel and the second flow channel; the first flow channel communicates with an evaporator outlet, and the second flow channel communicates with a condenser outlet; a heat exchanger (equivalent to an outdoor evaporator) is used for refrigeration, and a liquid refrigerant is gasified in a first flow channel and flows out from an outlet of the evaporator; the heat exchanger (equivalent to an outdoor condenser) dissipates heat, the drainage device introduces the gaseous refrigerant in the first flow channel into the second flow channel to be liquefied, and the liquefied gaseous refrigerant flows out of an outlet of the condenser.
本发明提供一种室外热交换器及电动汽车,属于热交换器结构技术领域。本电动汽车通过第一流道由多根纵向布置的蒸发扁管的设计,在第一流道参与制冷的工作过程中,蒸发扁管表面结霜,当对其进行化霜时会产生水,因为自身的重力,能够顺利从蒸发扁管表面落下,相比于横向布置的蒸发扁管,更利于蒸发扁管表面的化霜。本室外热交换器包括热交换器,热交换器包括第一流道和第二流道;第一流道和第二流道之间安装有引流装置;第一流道连通有蒸发器出口,第二流道连通有冷凝器出口;热交换器(相当于室外蒸发器)制冷,液态冷媒在第一流道内气化,从蒸发器出口流出;热交换器(相当于室外冷凝器)散热,引流装置将第一流道内的气态冷媒引入第二流道内液化,从冷凝器出口流出。
