Abstract
(EN)
The present invention provides a battery box. The battery box comprises a lower box body. The lower box body comprises a first plate, comprising a bottom wall; and a peripheral wall, connected to the periphery of the bottom wall and extends upwards, the bottom wall and the peripheral wall forming an accommodating space having an upward opening in the height direction. A second plate is fixed to the bottom wall from the lower portion and jointed with the bottom wall to form a liquid inlet flow path, a liquid outlet flow path, and a main flow path communicated with the liquid inlet flow path and the liquid outlet flow path. The main flow path comprises a first main flow path, a second main flow path, and multiple parallel branch flow paths communicated with the first main flow path and the second main flow path. In the battery box of the present invention, the first plate and the second plate are jointed to form the lower box body and form a heat exchange flow path, and the box body and the heat exchange flow path are integrally formed, so that the overall weight is reduced; in addition, due to the design of the external heat exchange flow path, the influence of liquid leakage of the heat exchange flow path on a battery in the battery box is effectively avoided; furthermore, the main flow path formed by jointing the first plate and the second plate is short in a heat exchange path and uniform in heat exchange, and the heat exchange effect is improved.

La présente invention concerne un bac de batterie. Le bac de batterie comprend un corps de bac inférieur. Le corps de bac inférieur comprend une première plaque, comprenant une paroi inférieure; et une paroi périphérique, reliée à la périphérie de la paroi inférieure et s'étend vers le haut, la paroi inférieure et la paroi périphérique formant un espace de réception ayant une ouverture vers le haut dans la direction de la hauteur. Une seconde plaque est fixée à la paroi inférieure à partir de la partie inférieure et jointe à la paroi inférieure pour former un trajet d'écoulement d'entrée de liquide, un trajet d'écoulement de sortie de liquide, et un trajet d'écoulement principal en communication avec le trajet d'écoulement d'entrée de liquide et le trajet d'écoulement de sortie de liquide. Le trajet d'écoulement principal comprend un premier trajet d'écoulement principal, un second trajet d'écoulement principal, et de multiples trajets d'écoulement de dérivation parallèles en communication avec le premier trajet d'écoulement principal et le second trajet d'écoulement principal. Dans le bac de batterie de la présente invention, la première plaque et la seconde plaque sont jointes pour former le corps de bac inférieur et former un trajet d'écoulement d'échange de chaleur, et le corps de bac et le trajet d'écoulement d'échange de chaleur sont formés d'un seul tenant, de telle sorte que le poids total est réduit; en outre, du fait de la conception du trajet d'écoulement d'échange de chaleur externe, l'influence de fuite de liquide du trajet d'écoulement d'échange de chaleur sur une batterie dans le bac de batterie est efficacement évitée; en outre, le trajet d'écoulement principal formé en joignant la première plaque et la seconde plaque est court dans un trajet d'échange de chaleur et uniforme en échange de chaleur, et l'effet d'échange de chaleur est amélioré.
