PROBLEM TO BE SOLVED: To provide a battery cooling device that can improve heat conduction, convection, and heat radiation to the outside, and achieve effective cooling of a battery.SOLUTION: A battery cooling device 1 comprises: a plurality of battery cells 3; a case 2 housing the plurality of battery cells 3; a blower 4 installed inside the case 2 for circulating air to cool the plurality of battery cells 3 inside the case 2; and a circulation passage 5 formed inside the case 2. The circulation passage 5 is formed inside the case 2 and forms a continuous flow path of air which is drawn in to the blower 4 after the air having flowed out of the blower 4 exchanges heat with the plurality of battery cells 3. The circulation passage 5 includes a collective passage 53 where air after having changed heat with the plurality of battery cells 3 gathers and flows in the same direction toward the blower 4. |
