A battery cooling device capable of cooling an entire battery more evenly includes a one-side heat exchanger configured to cool a one side surface, and an other-side heat exchanger configured to cool the other side surface, which is a surface facing the one side surface. The one-side heat exchanger includes heat exchange units from a one-side first heat exchange unit to a one-side nth heat exchange unit in an order in which refrigerant flows. The other-side heat exchanger includes heat exchange units from an other-side nth heat exchange unit to an other-side first heat exchange unit in the order in which refrigerant flows. The other-side first heat exchange unit to the other-side nth heat exchange unit are provided at positions where the other-side first heat exchange unit to the other-side nth heat exchange unit face the one-side first heat exchange unit to the one-side nth heat exchange unit, respectively.

Battery cooling device

To provide a battery temperature adjustment unit capable of efficiently supplying air adjusted to an appropriate temperature to a battery. A unit provided in a module case accommodating a battery includes a unit case having an air inlet and an air outlet, a heat exchanger disposed in the unit case, and a blower disposed in the unit case, in which air in the module case is sucked through the air inlet by the blower while being blown out through the air outlet and circulates through the module case and the air blown out through the air outlet includes air that has passed through the heat exchanger and air that has not passed through the heat exchanger. The unit also includes a heater disposed in parallel with a heat exchanger for cooling or disposed closer to the air inlet than the heat exchanger for cooling.

Battery temperature adjustment unit and vehicle having said unit installed

To provide a safety device of a battery temperature control system for an EV or an HEV capable of preventing an electric shock due to the electrical conduction across terminals of batteries in the event of a vehicle collision. A safety device used in a temperature control system of a battery for a vehicle, including a first heat exchange unit () which includes a first heat exchange section () filled with a liquid-state heat medium into a pipe () and exchanging heat with a battery (B) by the heat medium, and a second heat exchange unit () which includes a second heat exchange section () heating or cooling the heat medium subjected to heat exchange in the first heat exchange section (), wherein the heat medium existing in the first heat exchange section is discharged to the outside of the first heat exchange section, for example, under a predetermined condition such as a vehicle collision.
