Embodiment 1
[0039] like Figure 1-3 As shown, a safe and energy-saving lithium battery pack dual-mode thermal management system in this embodiment includes horizontal cells in the battery pack, a liquid-cooled plate-tube heat exchanger 2 attached to the outside of the battery pack shell 1, and an outer shell. An air-cooling module is installed, and the side of the external air-cooling module is a fan 10, and the inside has air-cooling fins 9. The horizontal cells in the battery pack are divided into four layers, each layer has three vertical and horizontal layers. The upper and lower surfaces of the three battery units 5 in each horizontal layer are attached to two sets of micro heat pipe arrays 6 extending in the lateral direction. The micro heat pipe array 6 is a flat heat conductor with a porous structure formed by extrusion of a metal material, and has a plurality of micro heat pipes arranged side by side that are not connected to each other and operate independently, and the hydrauli...
Embodiment 2
[0048] In order to ensure that the temperature difference between the air inlet and outlet of the air-cooling module is small, so that the temperature difference of all batteries is not higher than 5°C, the air duct of the air-cooling module in this embodiment is a static pressure box, as shown in Figure 5 As shown, other structures and working methods are similar to Embodiment 1.
Embodiment 3
[0050] The internal structure of the battery of this embodiment is as Image 6 As shown, only the lower side has the micro heat pipe array, both sides have the protruding part 61 and are bent upwards, and other structures and principles are consistent with the first embodiment.
