Battery system having an evaporative cooling member with a plate portion and a method for cooling the battery system
First Claim
1. A battery system, comprising:
- an external enclosure having a bottom enclosure portion, the bottom enclosure portion having a peripheral portion and a first recessed portion, the peripheral portion being disposed around and coupled to an upper end of the first recessed portion, the peripheral portion extending outwardly from the first recessed portion, the recessed portion defining a first recessed region therein;
an insulative layer disposed in the first recessed region of the bottom enclosure portion, the insulative layer defining a second recessed region therein;
an evaporative cooling member disposed in the second recessed region of the insulative layer and in direct abutting contact with the insulative layer, the evaporative cooling member having a rectangular-shaped plate portion and a serpentine-shaped conduit therein, the rectangular-shaped plate portion further having a serpentine-shaped channel therein, the serpentine-shaped conduit being disposed in the serpentine-shaped channel and thermally communicating with the rectangular-shaped plate portion;
a battery module having a housing, a battery cell, and a solid cooling fin;
the housing configured to hold the battery cell therein, the solid cooling fin having first and second panel portions, the first panel portion being disposed in direct abutting contact with the battery cell, the second panel portion extending through the housing and being disposed on the second side of the rectangular-shaped plate portion of the evaporative cooling member, the solid cooling fin configured to conduct heat energy from the battery cell to the evaporative cooling member;
the housing of the battery module being disposed in direct abutting contact with a portion of the insulative layer and the peripheral portion of the bottom enclosure portion;
the evaporative cooling member configured to receive a gaseous-liquid refrigerant in the serpentine shaped conduit and to transition the gaseous-liquid refrigerant into a gaseous refrigerant utilizing the heat energy received from the solid cooling fin;
the external enclosure defining a first enclosed region that holds the evaporative cooling member and the battery module therein.

Abstract
A battery system and a method for cooling the battery system are provided. The system includes an evaporative cooling member, and a battery module having a housing, a battery cell, and a solid cooling fin. The housing holds the battery cell therein. The solid cooling fin has first and second panel portions. The first panel portion is disposed against the battery cell. The second panel portion extends through the housing and is disposed on the evaporative cooling member. The solid cooling fin conducts heat energy from the battery cell to the evaporative cooling member. The evaporative cooling member receives a gaseous-liquid refrigerant and transitions the gaseous-liquid refrigerant into a gaseous refrigerant utilizing the heat energy received from the solid cooling fin.
