Abstract
(EN)
A battery pack, comprising: a frame body, enclosing an accommodating space which is closed in the circumferential direction and open in the height direction; a heat exchange plate, which is fixed below the frame body and closes an opening at the lower side of the accommodating space. The heat exchange plate comprises: a main body portion, provided with a heat exchange flow path; a fixing portion, connected to the entire peripheral edge of the main body portion. The fixing portion is provided with a plurality of notches, each notch being inwardly recessed from ends of the fixing portion, the plurality of notches being arranged at intervals along the entire peripheral edge of the fixing portion, a protrusion being formed between two adjacent notches, the protrusions being fixedly connected to the frame body. The design of the notches in the present battery pack reduces the contact area of the heat exchange plate with the frame body, thereby reducing heat transfer between the heat exchange plate and the frame body, and improving a heat exchange effect of the heat exchange plate with a battery module.

Bloc-batterie, comprenant : un corps de cadre, renfermant un espace de réception qui est fermé dans la direction circonférentielle et ouvert dans la direction de hauteur ; une plaque d'échange de chaleur, qui est fixée sous le corps de cadre et ferme une ouverture au niveau du côté inférieur de l'espace de réception. La plaque d'échange de chaleur comprend : une partie corps principal, pourvue d'un chemin d'écoulement d'échange de chaleur ; une partie de fixation, reliée à l'ensemble du bord périphérique de la partie corps principal. La partie de fixation est pourvue d'une pluralité d'encoches, chaque encoche étant en retrait vers l'intérieur à partir des extrémités de la partie de fixation, la pluralité d'encoches étant agencées à des intervalles le long de l'ensemble du bord périphérique de la partie de fixation, une saillie étant formée entre deux encoches adjacentes, les saillies étant reliées à demeure au corps de cadre. La conception des encoches dans le présent bloc-batterie réduit la zone de contact de la plaque d'échange de chaleur avec le corps de cadre, ce qui permet de réduire le transfert de chaleur entre la plaque d'échange de chaleur et le corps de cadre, et d'améliorer un effet d'échange de chaleur de la plaque d'échange de chaleur avec un module de batterie.

根据本发明的电池包包括:包括:框体,围成周向封闭且在高向开口的收容空间;换热板,固定于框体的下方并封闭收容空间下侧的开口。换热板包括:主体部,设有换热流道;以及固定部,连接于主体部的整个周缘,固定部设有多个缺口,各缺口由固定部的端部向内凹入,多个缺口沿固定部的整个周缘间隔布置,相邻两个缺口之间形成有突起,突起固定连接于框体。在根据本发明的电池包中,缺口的设计减少了换热板与框体的接触面积,从而减少了换热板与框体之间的热传递,提高了换热板与电池模组的换热效果。
