The invention provides a heat exchange method and a heat exchange system. After the vehicle starts to run, obtaining heating data of a plurality of heating systems of the vehicle in the current preset period; the plurality of heating systems comprise an electric drive system, a battery system and a passenger compartment system; on the basis of the heating data of each heating system, the estimated heat exchange output of the heat exchange system corresponding to each heating system in the next preset period is determined; on the basis of the estimated heat exchange output of each heat exchange system, a refrigerant valve control strategy of each heat exchange system in the next preset period is confirmed; and in the next preset period, each heat exchange system conducts heat exchange according to the refrigerant valve control strategy. The technical problems that in the prior art, a heat dissipation system only dissipates heat when the temperature of the parts rises, targeted heat dissipation cannot be conducted on the parts according to the operation conditions of the parts, and the heat dissipation intensity and the adjustable range of the heat dissipation intensity are limited are solved.
本发明提供了一种热交换方法和热交换系统。车辆开始行驶后,获取车辆多个发热系统在当前预设周期内的发热数据;多个发热系统包括电驱系统、电池系统以及乘员舱系统;基于每一发热系统的发热数据,确认下一预设周期内每一发热系统对应的换热系统的预估换热出力;基于每一换热系统的预估换热出力,确认下一预设周期内每一换热系统的冷媒阀控制策略;在下一预设周期内,每一换热系统根据所述冷媒阀控制策略进行热交换。本发明解决了现有技术中存在的散热系统仅在部件的温度升高时散热,不能根据各个部件的运转情况来对各部件进行针对性散热,且其散热强度以及散热强度的可调节范围有限的技术问题。
