A heatsink or heat exchanger for one or more power modules of an inverter or a converter comprises a coolant flow channel, comprised of a plurality of coolant flow channel portions that form a switchback or serpentine flow path, and that is adapted to circulate coolant inside the heat exchanger or heatsink. One or more vents can be provided inside the heat exchanger or heatsink to pass air from one coolant flow channel portion to an adjacent coolant flow channel portion.

Heatsink configuration and arrangment for inverter and systems, components, and methods thereof

A work machine with a remote diagnostic system includes a combustion engine, a pump, a coolant temperature sensor to monitor and transmit a coolant fluid temperature, a pressure sensor coupled to an inlet of the pump, and a controller. The pressure sensor is configured to monitor and transmit a coolant fluid pressure. The controller is operatively associated with the engine, the coolant fluid temperature sensor, the pressure sensor and an equipment care advisor module. The equipment care advisor module is configured to monitor the coolant fluid temperature during a start-up of the work machine, monitor the coolant fluid pressure during the start-up of the work machine, calculate an expected coolant fluid pressure based on the monitored coolant fluid temperature and the monitored coolant fluid pressure, and generate a failure code indicating a combustion gas leak when the monitored coolant fluid pressure exceeds the expected coolant fluid pressure.

Combustion gas leak detection strategy

A radiator includes a radiator frame, an array of tube assemblies each including a coolant tube and a tube clip supported in the radiator frame, and a lateral bump stop fitted between the array of tube assemblies and the radiator frame. The lateral bump stop includes cushions arranged in a staggered cushion pattern complementary to a staggered packing pattern of the tube assemblies with each of the cushions in contact with the tube clip of one of the tube assemblies.

Radiator and lateral bump stop therefor

A method for thermostat failure detection in an engine cooling system is provided. The engine cooling system includes a coolant pump and a thermostat for providing a coolant flow between an engine and a radiator. The method includes determining one or more engine parameters. Further, a pressure difference between a coolant pump inlet pressure and a coolant pump outlet pressure is determined corresponding to the one or more engine parameters. The thermostat failure is detected when the determined pressure difference is outside a predefined range of pressure change defined corresponding to the determined one or more engine parameters.

Method and system for detecting thermostat failure in an engine cooling system

A cooling package mounting assembly for a machine is provided. The cooling package mounting assembly includes a first elongated frame member and a second elongated frame member. The cooling package mounting assembly also includes a first top coupling bracket, a second top coupling bracket, a first bottom coupling bracket and a second bottom coupling bracket. The cooling package mounting assembly includes a mounting arrangement coupled to at least one of the first elongated frame member and the second elongated frame member. In a first configuration, the mounting arrangement is configured to removably support a first type of heat exchanger of the cooling package between the first elongated frame member and the second elongated frame member. In a second configuration, the mounting arrangement is configured to removably support a second type of heat exchanger of the cooling package between the first elongated frame member and the second elongated frame member.
