Battery cooling device

A battery cooling device that is connected to a refrigeration cycle including a compressor that compresses refrigerant, a condenser that condenses the refrigerant discharged from the compressor, and a refrigerant reservoir capable of storing excess refrigerant, the battery cooling device comprising:

• an expansion device configured to expand the refrigerant flowing out from the refrigeration cycle;
• a refrigerant distribution device configured to distribute the refrigerant flowing out from the expansion device to a one-side flow path and an other-side flow path;
• a one-side heat exchanger that include a plurality of heat exchange units and through which the refrigerant flowing through the one-side flow path flows;
• an other-side heat exchanger that include a plurality of heat exchange units and through which the refrigerant flowing through the other-side flow path flows;
• and
• a refrigerant merging device configured to merge the refrigerant flowing out from the one-side heat exchanger with the refrigerant flowing out from the other-side heat exchanger and cause the merged refrigerant to flow out to the refrigeration cycle,
• the battery cooling device cooling a battery by the one-side heat exchanger and the other-side heat exchanger,
• wherein the one-side heat exchanger is provided on a one side surface, which is any surface of the battery, and the other-side heat exchanger is provided on the other side surface, which is a surface facing the one side surface,
• wherein the heat exchange units that form the one-side heat exchanger, when a heat exchange unit through which the refrigerant flowing through the one-side flow path flows first is a one-side first heat exchange unit, and a heat exchange unit through which the refrigerant flowing out from the one-side first heat exchange unit flows next is a one-side second heat exchange unit, the one-side heat exchanger includes the heat exchange units from the one-side first heat exchange unit to a one-side nth heat exchange unit in an order in which the refrigerant flows,
• wherein the heat exchange units that form the other-side heat exchanger, when a heat exchange unit through which the refrigerant flowing through the other-side flow path flows first is an other-side nth heat exchange unit, and a heat exchange unit through which the refrigerant flowing out from the other-side nth heat exchange unit flows next is an other-side (n−1)th heat exchange unit, the other-side heat exchanger includes the heat exchange units from the other-side nth heat exchange unit to an other-side first heat exchange unit in the order in which the refrigerant flows, and
• 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.
