## Abstract

A vehicle cooling system for a vehicle defining a cab comprises a heat source and an evaporative cooling system. The heat source is supported by the vehicle. The evaporative cooling system is configured to evaporate water using heat from the heat source to form a supply of cool air for cooling the cab.

## Claims

### Claim 1

A vehicle cooling system for a vehicle defining a cab comprising:
a heat source supported by the vehicle;
an evaporative cooling system configured to evaporate water using heat from the heat source to form a supply of cool air for cooling the cab; and
a heat exchanger; wherein
cab air circulates through the heat exchanger and the cab; and
the heat exchanger exchanges heat between the cab air and the supply of cool air from the evaporative cooling system.

### Claim 2 (depends on 1)

A vehicle cooling system as recited in claim 1, further comprising:
a heat source housing defining a housing inlet and a housing outlet; wherein
the heat source is at least partly arranged within the heat source housing; and
air flows into the heat source housing through the housing inlet, around the heat source, and out of the housing outlet to transfer heat between the heat source and the evaporative cooling system.

### Claim 3 (depends on 1)

A vehicle cooling system as recited in claim 1, in which the evaporative cooling system comprises:
an evaporator element;
a water reservoir; and
a pump;
the pump forces water from the water reservoir to the evaporator element; and
heat from the heat source is transferred to the evaporator element.

### Claim 4 (depends on 3)

A vehicle cooling system as recited in claim 3, in which the evaporative cooling system further comprises:
a blower; wherein
the blower forces the supply of cool air from the evaporator element to the cab.

### Claim 5

A vehicle cooling system for a vehicle defining a cab comprising:
a generator supported by the vehicle;
an evaporative cooling system configured to evaporate water using heat from the generator to form a supply of cool air for cooling the cab; and
a heat exchanger; wherein
cab air circulates through the heat exchanger and the cab; and
the heat exchanger exchanges heat between the cab air and the supply of cool air from the evaporative cooling system.

### Claim 6 (depends on 5)

A vehicle cooling system as recited in claim 5, further comprising:
a generator housing defining a housing inlet and a housing outlet; wherein
the generator is at least partly arranged within the generator housing; and
air flows into the generator housing through the housing inlet, around the generator, and out of the housing outlet to transfer heat from the generator to the evaporative cooling system.

### Claim 7 (depends on 5)

A vehicle cooling system as recited in claim 5, in which the evaporative cooling system comprises:
an evaporator element;
a water reservoir; and
a pump;
the pump forces water from the water reservoir to the evaporator element; and
heat from the generator is transferred to the evaporator element.

### Claim 8 (depends on 7)

A vehicle cooling system as recited in claim 7, in which the evaporative cooling system further comprises:
a blower; wherein
the blower forces the supply of cool air from the evaporator element to the cab.

### Claim 9

A method of cooling a cab of a vehicle comprising the steps of:
supporting a heat source on the vehicle;
forming a supply of cool air for cooling the cab by evaporating water using heat from the heat source; and
providing a heat exchanger;
circulating through cab air through the heat exchanger and the cab; and
configuring the heat exchanger to exchange heat between the cab air and the supply of cool air from the evaporative cooling system.

### Claim 10 (depends on 9)

A method as recited in claim 9, further comprising the steps of:
providing a heat source housing defining a housing inlet and a housing outlet;
at least partly arranging the heat source within the heat source housing; and
transfer heat between the heat source and the evaporative cooling system by causing air to flow into the heat source housing through the housing inlet, around the heat source, and out of the housing outlet.

### Claim 11 (depends on 9)

A method as recited in claim 9, further comprising the steps of:
providing an evaporator element;
providing a water reservoir;
forcing water from the water reservoir to the evaporator element; and
transferring heat from the heat source to the evaporator element.

### Claim 12 (depends on 11)

A method as recited in claim 11, further comprising the step of forcing the supply of cool air from the evaporator element to the cab.
