Problems solved by technology

[0002] In the related art, the battery pack assembly of the vehicle is generally installed on a tray, and the tray and the outer cover jointly define a cavity for accommodating the battery assembly, and various cooling water channels or cooling air channels with complex structures are arranged in the cavity. The space of the cavity is large, and the cooling water channel and the cooling air channel are not compatible with each other, so the versatility is not strong, especially for the water-cooled structure, the routing of the cooling water channel is complicated, and once a leak occurs, it is likely to cause a short circuit of the battery components. Affect the service life and safety of battery pack components

Abstract

The invention discloses a first sub-baseplate. The first sub-baseplate comprises a main body part, and multiple sealing parts, wherein a flow path is arranged in the main body part, and multiple opening parts are arranged in the middle of the flow path; multiple sealing parts seal multiple opening parts in one-to-one correspondence to form runners. The first sub-baseplate disclosed by the invention integrates the runners in the board body so as to reduce the volume requirement on a cavity of a battery component, the layout of the runner is more concise, the route of the runner is more clear; the first sub-baseplate can be compatible with the water-cooling and air-cooling; especially in the water-cooling mode, the coolant can directly flow out even if the coolant leaks, the short-circuit ofthe battery component is avoided, the use of the battery component is safer; the first sub-baseplate can realize collapsing energy absorption in collision, thereby playing good protection effect on the battery component.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a first sub-floor used for heat dissipation. Background technique [0002] In the related art, the battery pack assembly of the vehicle is generally installed on a tray, and the tray and the outer cover jointly define a cavity for accommodating the battery assembly, and various cooling water channels or cooling air channels with complex structures are provided in the cavity. This structure requires The space of the cavity is large, and the cooling water channel and the cooling air channel are not compatible with each other, so the versatility is not strong, especially for the water-cooled structure, the wiring of the cooling water channel is complicated, and once a leak occurs, it is likely to cause a short circuit of the battery components. Affect the service life and safety of battery pack components. Contents of the invention [0003] The present i...
