Vehicle engine cooling system without a fan

A fan-less cooling system in combination with a mobile vehicle, comprising:

• a vehicle chassis engaged to a driver cab;
• axles with wheels suspended to said chassis;
• an engine for driving said axles and wheels engaged to said chassis;
• a compressed air reservoir engaged to said chassis;
• a heat exchanger and an expansion duct connecting said air reservoir said heat exchanger;
• coolant piping between said heat exchanger and said engine;
• wherein compressed air released from said air reservoir to said duct for expansion across a face of said heat exchanger provides for removal of heat from said cooling piping supplied to said engine;
• an end of said expansion duct connected to said reservoir being of a lower cross-sectional area than an end of said expansion duct connected to said face of said heat exchanger;
• an engine electronic controller for monitoring engine parameters and said electronic controller engaged to said engine;
• said electronic controller electrically engaged to control releases of compressed air from said reservoir to said expansion duct;
• and
• said controller programmed that upon sensing a parameter change indicating a need for supplemental cooling for an auxiliary system of said engine performing the step of directing an outlet control of said air reservoir to release air to said expansion duct.

A fan-less cooling system for providing cooling to engine auxiliaries of a mobile vehicle, the vehicle having a vehicle chassis engaged to a driver cab, and the chassis having axles with wheels, comprising:

• a compressed air reservoir for engagement to the chassis;
• a heat exchanger and an expansion duct connecting said air reservoir said heat exchanger;
• coolant piping for engagement between said heat exchanger and the engine;
• and
• wherein compressed air released from said air reservoir to said duct for expansion across a face of said heat exchanger provides for removal of heat from said cooling piping supplied to the engine.

A fan-less cooling system in combination with a mobile vehicle, comprising:

• a vehicle chassis engaged to a driver cab;
• axles with wheels suspended to said chassis;
• an air conditioning system for providing cooling to said cab;
• a compressed air reservoir engaged to said chassis;
• a heat exchanger and an expansion duct connecting said air reservoir said heat exchanger;
• coolant piping between said heat exchanger and said air conditioning system;
• and
• wherein compressed air released from said air reservoir to said duct for expansion across a face of said heat exchanger provides for removal of heat from said cooling piping supplied to said air conditioning system.

A fan-less cooling system in combination with a mobile vehicle, comprising:

• a vehicle chassis engaged to a driver cab;
• axles with wheels suspended to said chassis;
• an air conditioning system for cooling air within said cab;
• a compressed air reservoir engaged to said chassis;
• a heat exchanger and an expansion duct connecting said air reservoir said heat exchanger;
• coolant piping between said heat exchanger and said air conditioning system;
• wherein compressed air released from said air reservoir to said duct for expansion across a face of said heat exchanger provides for removal of heat from said cooling piping supplied to said air conditioning system;
• an end of said expansion duct connected to said reservoir being of a lower cross-sectional area than an end of said expansion duct connected to said face of said heat exchanger;
• an air conditioning controller for monitoring cab parameters;
• said electronic controller electrically engaged to control releases of compressed air from said reservoir to said expansion duct;
• and
• said controller programmed that upon sensing a parameter change indicating a need for supplemental cooling for said cab performing the step of directing an outlet control of said air reservoir to release air to said expansion duct.

A fan-less cooling system for providing cooling to an air conditioning system of a cab of a mobile vehicle, the vehicle having a vehicle chassis engaged to the driver cab, comprising:

• a compressed air reservoir for engagement to the vehicle;
• a heat exchanger and an expansion duct connecting said air reservoir said heat exchanger;
• coolant piping for engagement between said heat exchanger and the air conditioning system;
• and
• wherein compressed air released from said air reservoir to said duct for expansion across a face of said heat exchanger provides for removal of heat from said cooling piping supplied to the air conditioning system.
