Detailed description of the invention
Embodiment of the present utility model as shown in Figure 1, Figure 2, Figure 3, Figure 4.
The designed liquid heat exchange battery module of the utility model is made up of the battery unit being mutually electrically connected, described sheetBattery unit is made up of one or multiple sheet battery cells (sheet battery pack) parallel with one another, as shown in Figure 1. Liquid heat exchangeIn battery module, arrange multiple battery cavities, battery cavities sealed bottom, battery cell or battery pack are placed in battery cavities, battery cavities quiltThe space that is filled with cooling fluid surrounds, and all spaces that is filled with cooling fluid are all interconnected, as shown in Figure 2 and Figure 3. InstituteState the entrance and exit that battery module packed and be provided with cooling fluid, as shown in Figure 4. Described liquid heat exchange battery moduleBattery cavities shape can design according to the type of sheet battery cell and quantity.
Between described battery cavities, be provided with dividing plate, the mobile of cooling fluid play the guiding role. By dividing plate by battery moduleBe divided into multiple passages, the backflow phenomenon preventing, strengthens the heat exchange between cooling fluid and battery cavities.
Described liquid heat exchange modular structure can be also other and the similar energy-storage module of sheet battery structure, as superElectric capacity etc.
Battery being carried out when cooling, can adopt refrigeration subsystem to rely on cold-producing medium to freeze to cooling fluid, also canThe dependence of employing heat exchanger is air-cooled freezes to cooling fluid, and adds liquid reserve tank in system, adopts pump to drive cooling fluid to existIn battery module, flow.
In the time that cooling fluid is heated, can in battery case, add Electric radiant Heating Film, can heat cold by Electric radiant Heating Film is switched onBut liquid, Electric radiant Heating Film can be arranged in liquid heat exchange battery module bottom, also can arrange along liquid heat exchange battery module inwall Electric radiant Heating FilmCan arrange on one side, also can arrange polygon.
