在一可选实施例中，上述的下箱体30的一侧端设有若干散热槽条31，以实现对置于下箱体30内的制冷动力组件进行散热。
在一实施例中，请参阅图4，上述的制冷动力组件包括压缩机80、冷凝器70以及毛细管，压缩机80与冷凝器70连接，冷凝器70与毛细管连接，毛细管与蒸发器60连接，蒸发器60与压缩机80连接。
气态制冷剂穿过冷凝器70遇到毛细管，但毛细管的管道比较细，使得大量制冷剂拥挤在冷凝器70内。压缩机80驱动冷凝器70将制冷剂推向毛细管，而毛细管堵着不让制冷剂通过，因此滞留在冷凝器70中的制冷剂越来越多，压力也就越来越大了，压力增大后，气态制冷剂开始液化，液化的过程中伴随着吸热，于是滞留在冷凝器70前半段即靠近压缩机80方向的制冷剂就是高温高压的液态；这些制冷剂在冷凝器70中慢慢降温，直至降低到室温，开始慢慢排队通过毛细管；蒸发器60的管道较粗，通过了毛细管的制冷剂压力突然降低，于是液态制冷剂开始沸腾并气化，此过程中伴随吸热，直至制冷剂完全通过蒸发器60后，也完全成了常温常压的气态；气态制冷剂重新通过压缩机80，继续新一轮的循环。借助制冷剂的状态的变化，实现对保温腔内的温度的调节，实用且环保。
压缩机80启动电源时，蒸发器60开时制冷降温，此时风扇50启动，将冷风吹入保温箱体，保温箱体内的空气会通过通槽22以及插槽13传入背包内，进而达到对背包的空腔内的物体的冷却，背包的东西可以不需取出就可以冷却。
在一可选实施例中，还可以在保温腔内设置一个挡板，该挡板将保温腔分为第一腔体以及第二腔体，其中，将蒸发器60以及风扇50放置在第二腔体内，且该挡板上设有多个通风槽，第一腔体放置物品，从而实现该保温结构的两用型， 既可以对背包进行冷却保温，还可以对单独的物品进行冷却保温，提高整个系统的实用性。
在一实施例中，请参阅图6，下箱体30内设有温度控制组件，温度控制组件分别与压缩机80与风扇50连接。
具体地，上述下箱体30上设有显示屏32，用于显示保温腔当前的温度。
具体地，在一可选实施例中，请参阅图7，上述的温度控制组件包括电源、变压器T1、热敏电阻R5以及运算放大器LM358，压缩机80与风扇50分别通过继电器K1与电源连接；当温度达到设定值时，热敏电阻R5变小，运算放大器LM358工作，以使得继电器K1断开，压缩机80与风扇50停止工作。
当整个系统接上电源时，电源电流分为两路L路和N路，L路是通过继电器K1，N路通过开关SW1到压缩机80和风扇50，此时压缩机80和风扇50开始工作制冷。
且L路经过变压器T1后，经过桥式整流电路B1，经过稳压器Q2进行电源稳压，经过滤波电容C2滤波，到热敏电阻R5，当温度达到设定值时，热敏电阻R5变小，从而运算放大器LM358开始工作，再经过Mos管Q1到继电器K1，以使得继电器K1断开，进而断开压缩机80和风扇50的供电线路，从而关闭压缩机80和风扇50，进而到达控制温度的目的。
在一可选实施例中，插槽13的个数为至少两个，插条21的个数与插槽13的个数一致，多个插槽13可以实现空气的进出。
当保温箱体的插条21插设在背包的插槽13内，将背包放置在支架40上，接上电源，此时压缩机80启动，蒸发器60开始制冷，同时风扇50将冷气吹入保温箱体的保温腔内，也进一步将冷气吹入背包的空腔内，此时背包内的需要制冷的物品开始降温，当背包内部温度达到设定好的温度时，而背包内空腔的温度与保温腔内的温度又保持一致，利用温度控制组件驱动压缩机80停止工作，也驱动风扇50停止工作，此时便可根据实际情况取出背包，将背包上的密封条插设到背包的插槽13内，以使得背包内的空腔处于一个密封的状态，便可进行该背包的使用；当背包需要一直保温时，就将背包一直放置在支架40上，密封条不插设在插槽13内，保温箱体上的插条21一直插设在背包的插槽13内；当需要使用背包时，则重复上述的取背包流程，操作方便。
在一可选实施例中，上述的压缩机80可以分为直流压缩机80和/或交流压缩机80，以使得整个系统可家用和车用。
当出现紧急情况时，可以随时将制冷好的物品连通背包随时取走和随时保温；适用于医院有需要长期保鲜和保温的物品的情况，且空间小，省电，温度可以调节；出现紧急情况时，可以立即取走；在野外可以放在车里保温，也可以立即取走；重量较轻，便于携带，减轻劳动强度。
在一可选实施例中，上箱体20的侧壁设有密封条，当背包与保温结构分离时，密封条插设在通槽22内，实现对通槽22的密封，当然，该密封条的外端设有吸盘密封边，该密封条插设在通槽22内时，该吸盘密封边吸合在插条21的外端面上，以提高对通槽22的密封性。
在一可选实施例中，该插条21的外周设有硅胶层，该插条21的尺寸与插槽13的尺寸一致，硅胶层可以起到密封插条21与插槽13之间的缝隙。
上述的制冷型急救背包保温系统，通过设置背包与保温结构的可分离结构，当需要使用到背包内的物品时，只需要将背包的插槽13与保温结构的插条21分离，将背包上的密封条插设在插槽13内，便可单独取走背包；当需要对背包内的物品进行保温时，则只需要将插条21插设在插槽13内，便可利用制冷结构对背包进行制冷，实现当出现紧急情况时，可以将制冷东西随时取走和随时保温，适用于户外和室内。
在一实施例中，还提供了制冷型急救背包保温系统的工作方法，该方法包括：
当背包与保温结构不分离时，插条21插设在插槽13内，通槽22与空腔连通；利用保温结构对背包内的物体进行保温；
当背包与保温结构分离时，密封块15插设在插槽13内。
需要说明的是，所属领域的技术人员可以清楚地了解到，上述制冷型急救背包保温系统的工作方法的具体实现过程，可以参考前述的制冷型急救背包保温系统实施例中的相应描述，为了描述的方便和简洁，在此不再赘述。
