一些新能源车辆在设置室内的冷凝器及蒸发器的同时，需要设置室外热交换器作为蒸发器或冷凝器。当车辆处于制冷状态时，室外热交换器作为冷凝器，室外热交换器与室内的蒸发器构成第一回路；当车辆处于制热状态时，室外热交换器作为蒸发器，室外热交换器与室内的冷凝器构成第二回路，制冷过程和制热过程分别在两个回路中进行，结构复杂。
有鉴于此，本申请提供一种热管理系统及新能源车辆。下面结合附图，对本申请的热管理系统及新能源车辆进行详细说明。在不冲突的情况下，下述的实施例及实施方式中的特征可以相互组合。
参见图1至图4所示，本申请提供一种热管理系统10，包括制冷剂回路11、分隔设置的第一空间12和第二空间13。第一空间12与室外空间14和室内空间15中的至多一者连通。当热管理系统10应用于新能源车辆时，室外空间14可以指新能源车辆外部的环境，室内空间15可以指新能源车辆的驾驶室。其中，第一空间12可以与室外空间14连通，也可以与室内空间15连通，还可以与室外空间14和室内空间15都不连通。在一些实施例中，热管理系统10还包括第三风门20和第四风门21。第三风门20可开合地设置于第一空间12和室外空间14之间。例如，第三风门20可以可旋转地设置于第一空间12和室外空间14之间。当第三风门20打开时，第一空间12与室外空间14连通；当第三风门20关闭时，第一空间12与室外空间14不连通。第四风门21可开合地设置于第一空间12和室内空间15之间。例如，第四风门21可以可旋转地设置于第一空间12和室内空间15之间。当第四风门21打开时，第一空间12与室内空间15连通；当第四风门21关闭时，第一空间12与室内空间15不连通。第二空间13与室外空间14和室内空间15中的至多一者连通。其中，第二空间13可以与室外空间14连通，也可以与室内空间15连通，还可以与室外空间14和室内空间15都不连通。在一些实施例中，热管理系统10还包括第五风门22和第六风门23。第五风门22可开合地设置于第二空间13和室外空间14之间。例如，第五风门22可以可旋转地设置于第二空间13和室外空间14之间。当第五风门22打开时，第二空间13与室外空间14连通；当第五风门22关闭时，第二空间13与室外空间14不连通。第六风门23可开合地设置于第二空间13和室内空间15之间。例如，第六风门23可以可旋转地设置于第二空间13和室内 空间15之间。当第六风门23打开时，第二空间13与室内空间15连通；当第六风门23关闭时，第二空间13与室内空间15不连通。

本申请提供的热管理系统10，蒸发器16设置于第一空间12内，第一空间12与室外空间14和室内空间15中的至多一者连通。冷凝器17设置于第二空间13内，第二空间13与室外空间14和室内空间15中的至多一者连通。在热管理系统10处于制冷状态时，可以将第三风门20关闭，第四风门21打开，以将第一空间12与室内空间15连通，将蒸发器16产生的冷风输出给室内空间15。此时，可以将室外新风吹向冷凝器17，可以将第五风门22打开，第六风门23关闭，将热风吹至室外空间14。在热管理系统10处于制热状态时，可以将第五风门22关闭，第六风门23打开，以将第二空间13与室内空间15连通，将冷凝器17产生的热风输出给室内空间15。可以将第三风门20打开，第四风门21关闭，将冷风吹至室外空间14。如此，无需设置室外热交换器、且在制冷状态和制热状态使用同一回路，热管理系统10的结构更加简单，这样可以减少管路数量、减少制冷剂加注量，从而减少了装配时间，节约了成本。且在制冷状态和制热状态使用同一回路可以使得制冷剂回路11的流动阻力更低、降低了能量的消耗，节约了整体的能量。
在一些实施例中，热管理系统10包括第一传感器59和第二传感器60，第一传感器59设置于与进气口24连接的管路上，第二传感器60设置于与出气口25连接的管路上，第一传感器59和第二传感器60用于检测压缩机19的进气口24和出气口25处的压力 和温度，从而可以根据检测到的压力和温度调节压缩机19的转速。

在一些实施例中，热管理系统10包括第一风机50和第二风门51。其中，第一风机50可以是鼓风机。第一风机50设置于第一空间12内，第一空间12设置有第一风口52，第一风机50用于将第一风口52处的风输送至蒸发器16的进风侧。第二风门51可旋转地设置于第一风口52，以使第一空间12与室外空间14和室内空间15中的至少一者连通。其中，第一空间12可以与室外空间14和室内空间15都连通，第一风机50可以将室外空间14和室内空间15的风输送至蒸发器16的进风侧。第一空间12可以与室外空间14和室内空间15中的一者连通，如此第一风机50可以将室外空间14或室内空间15的风输送至蒸发器16的进风侧。如此，可以在热管理系统10处于制热状态时，控制第二风门51旋转，使得第一空间12与室内空间15连通，第一空间12与室外空间14不连通。这使得第一风机50可以将室内空间15的风输送至蒸发器16的进风侧，如此可以完全吸收来自室内空间15的热量，减少能量的消耗。
在一些实施例中，热管理系统10包括第二风机53。其中，第二风机53可以是鼓风机。第二风机53设置于第二空间13内，第二空间13设置有第二风口54，第二风口54连通室外空间14和第二空间13，第二风机53用于将第二风口54处的风输送至冷凝器17的进风侧。如此，可以将室外空间14的风输送至冷凝器17的进风侧。可以在第一空间12内设置第一风机50，在第二空间13内设置第二风机53，使得冷凝器17和蒸发器16可以设置有用于进风的独立风口。
