## Abstract

A vehicle includes a housing case, a power storage module provided in the housing case, an electronic device provided in the housing case, an exhaust pipe disposed laterally of the housing case, and a cooling circuit including a cooling pipe through which refrigerant circulates. A portion of the cooling pipe is located between the electronic device and the exhaust pipe.

## Claims

### Claim 1

A vehicle comprising:
a housing case;
a battery pack provided in the housing case;
a battery electronic control unit provided in the housing case;
an exhaust pipe disposed laterally of the housing case; and
at least one cooling pipe through which refrigerant circulates,
wherein
a portion of the at least one cooling pipe is located between the battery electronic control unit and the exhaust pipe,
the at least one cooling pipe comprises:
a module cooling pipe disposed to face the battery pack and configured to cool the battery pack,
a device cooling pipe disposed to face the battery electronic control unit and configured to cool the battery electronic control unit, and
wherein, in a direction in which the refrigerant flows, an expansion valve disposed at an inlet of the module cooling pipe.

### Claim 2 (depends on 1)

The vehicle according to claim 1, wherein
in the direction in which the refrigerant flows, the device cooling pipe is located upstream of the module cooling pipe.

### Claim 3 (depends on 2)

The vehicle according to claim 2, wherein in a direction in which exhaust flows through the exhaust pipe, the battery electronic control unit is located upstream of the battery pack.

### Claim 4 (depends on 1)

The vehicle according to claim 1, wherein
in the direction in which the refrigerant flows, the device cooling pipe is located downstream of the module cooling pipe.

### Claim 5 (depends on 1)

The vehicle according to claim 1, wherein
the at least one cooling pipe further comprises:
a second device cooling pipe that is disposed to face the battery electronic control unit and cools the battery electronic control unit, and
in a direction in which the refrigerant flows, the device cooling pipe is located upstream of the module cooling pipe, and the second device cooling pipe is located downstream of the module cooling pipe.

### Claim 6 (depends on 1)

The vehicle according to claim 1, wherein the portion of the at least one cooling pipe is provided in the housing case.

### Claim 7 (depends on 1)

The vehicle according to claim 1, wherein the portion of the at least one cooling pipe is disposed flush with the battery electronic control unit.

### Claim 8 (depends on 1)

The vehicle according to claim 1, wherein in a direction in which exhaust flows through the exhaust pipe, the battery electronic control unit is located upstream of the battery pack.
