US 2021/0280930 A1 · BATTERY COOLING PLATE AND FLUID MANIFOLD

Abstract

A battery cooling plate includes a first plate and a second plate that are joined together at their respective edges, and are spaced apart to define a coolant volume therebetween. Turbulating inserts can be arranged side-by-side within the coolant volume and multiple rods can extend through the turbulating inserts to at least partially define flow barriers between coolant flow channels. A fluid manifold for the battery cooling plate includes a non-planar wall that extends along a length-wise direction of the fluid manifold to separate a fluid volume into a first portion and a second portion. A series of apertures are arranged along the length-wise direction and successive ones of the apertures are fluidly connected to the first portion and to the second portion in alternating sequence.

Dependent claims

A battery cooling plate comprising:

a turbulating insert arranged between a first planar surface and a second planar surface and bonded thereto;
a first coolant pass extending through the turbulating insert in a first direction;
a second coolant pass extending through the turbulating insert in a second direction opposite the first direction, the first and the second coolant passes being sequentially arranged;
and
a flow barrier arranged between the first coolant pass and the second coolant pass to prevent bypass flow between the first and second coolant passes, the flow barrier being at least partially defined by:
a convolution of the turbulating insert extending parallel to the first and the second directions;
a rod arranged within the convolution;
and
a pocket provided within an embossment extending from at least one of the first and the second planar surfaces, an end of the rod being received within the pocket.
