A cooling structure for batteries and electrical units, that cools the batteries being driving sources of a motor mounted in a vehicle capable of traveling by a driving force of the motor and electrical units for driving the motor, the cooling structure including: a plurality of battery boxes that each contain one of the batteries; cooling passages that are each formed in each of the battery boxes, through which cooling air flows; a merging part where downstream ends of the cooling passages of the battery boxes are merged with each other; and cooling portions of the electrical units, that are provided on a downstream side of the merging part, wherein the electrical units are disposed on a downstream side of the battery boxes.

The peel off between an ice making plate and an insulating layer or between the insulating layer and heating means is prevented so that an ice making operation can be performed efficiently. Also, a metal plate is insulated from the heating means reliably.An evaporation pipe 14 and electric heaters H1 to HN are provided in an ice making member 11. A coolant is circulatingly supplied through the evaporation pipe 14 so as to cool the ice making member 11 and ice making water is supplied to the ice making member 11 so as to form an ice block M during the ice making operation. During the deicing operation, heat is generated in the heaters H1 to HN by applying current so that the ice block M is removed from the ice making member 11 by melting. The ice making member 11, in a state that an insulating layer 12b lies between a metal plate 12a to which the evaporation pipe 14 is fixed and the heaters H1 to HN, is formed by bonding the metal plate 12a with the insulating layer 12b, and the insulating layer 12b with each of the heaters H1 to HN by thermocompression. Also, in addition to thermocompression bonding, the external outline of the heating means (H1 to HN) may be located inside the insulating layer 12b.

A bottom portion of a fuel tank of a motorcycle is prevented from being heated by engine heat to avoid an increase in fuel temperature. The fuel tank is behind and above the engine and a seat is behind the fuel tank. The seat includes a seat frame attached to the body frame and extending rearward, and a seat cushion mounted on the seat frame. The seat frame has an air introduction opening formed behind the seat cushion, and defines an air passage for guiding air introduced from the air introduction opening toward a bottom wall of the fuel tank.

A superconducting device has a rotor rotatable about an axis of rotation and a superconducting winding in a heat conducting winding carrier. The winding carrier has a central cooling agent cavity with a lateral cavity leading out of the winding carrier connected thereto. A cold head associated with a cooling unit is connected to a condenser unit which condenses the cooling agent. A fixed heat tube guiding the cooling agent is coupled to the condenser unit, protruding axially into the co-rotating lateral cavity and is sealed in relation thereto.

To efficiently cool heat generation rotary equipment being a target in a casing.A centrifugal fan 54 is attached to an inner plate 40b of a centrifugal clutch 40 being the heat generation rotary equipment, and an intake port 59a of the casing is arranged in the vicinity of a front face in the axial direction of the centrifugal fan 54. The centrifugal fan 54 is provided with a base plate 86 connected with the inner plate 40b of the centrifugal clutch 40, a plurality of fins 87 provided on the base plate 86, a blow-out hole 88 passing through the base plate 86 in the axial direction between arbitrary ajacent fins 87, and a guide wall 89 for guiding air directed toward an outer side in the radial direction on the base plate 86 into the blow-out hole 88. The air immediately after being introduced from the intake port is blown to the centrifugal clutch in a rear part through the blow-out hole.
