The invention relates to the technical field of battery heat dissipation, in particular to a heat dissipation device, a heat dissipation system and a vehicle. The heat dissipation device comprises a first vapor chamber which is provided with a first evaporation end and a first condensation end, and the first evaporation end is used for being connected to a battery; the second vapor chamber is provided with a second evaporation end, at least part of the second vapor chamber is used for being communicated with the external environment, and the second evaporation end is communicated with the first condensation end. Under the condition that the temperature is too high due to the fact that the temperature of the battery rises during operation, the battery can be cooled through the combined action of the first vapor chamber and the second vapor chamber, the second vapor chamber ensures that the first vapor chamber can continuously and stably work, and part of the second vapor chamber is communicated with the outside and exchanges heat with the external environment; the heat dissipation effect of the second vapor chamber is guaranteed, auxiliary heat dissipation of the battery is achieved, energy consumed by the vehicle in the battery heat management process is reduced, and the endurance mileage of the vehicle is increased.
本发明涉及电池散热的技术领域,更具体地说,本发明涉及一种散热装置、散热系统和车辆。其中,散热装置包括:第一均热板,设置有第一蒸发端和第一冷凝端,其中,第一蒸发端用于连接于电池;第二均热板,设置有第二蒸发端,至少部分第二均热板用于连通于外界环境,其中,第二蒸发端导通于第一冷凝端。在电池运行升温,导致温度过高的情况下,可通过第一均热板和第二均热板的共同作用对电池进行降温,且第二均热板保证了第一均热板能够持续稳定的工作,部分第二均热板和外界相连通,和外界环境进行热交换,保证了第二均热板的散热效果,实现对电池辅助散热,减少了车辆在电池热管理过程中消耗的能源,提高车辆的续航里程。
