Cooling device and engine system

The invention relates to the technical field of heat exchange devices, in particular to a cooling device and an engine system. The cooling device comprises a base, a first heat exchanger and a second heat exchanger. The first heat exchanger and the second heat exchanger are detachably connected with the base. The base is provided with a main liquid inlet flow channel, and the first heat exchanger and the second heat exchanger are both communicated with the main liquid inlet flow channel. According to the cooling device, a traditional cooler is broken up into parts and integrated on the same base, the structure is compact, and the occupied space is small. 本发明涉及换热装置技术领域，尤其是涉及一种冷却装置及发动机系统。本发明提供的冷却装置，包括：底座、第一换热器和第二换热器；所述第一换热器和所述第二换热器均与所述底座可拆卸连接；所述底座上设有总进液流道，所述第一换热器和所述第二换热器均与所述总进液流道连通。本发明提供的冷却装置将传统的冷却器化整为零，并且集成在同一底座上，结构紧凑，占用空间少。
