An energy storage device cooling system includes a housing, at least one energy storage device within the housing, and a coolant circuit including a first flow portion extending through the housing, the coolant circuit configured to supply coolant for heat exchange with the at least one energy storage device. The energy storage device cooling system also includes a chiller system including: a coolant supply, a heat exchanger, and an outlet in fluid communication with the first flow portion. The energy storage device cooling system also includes a controller configured to alter a function of the chiller system when a sensed temperature does not exceed a first temperature threshold.

Cooling system and method for energy storage

In one aspect, a pump-motor assembly is provided outside of and adjacent to a storage container that stores a back-up energy storage unit. The pump-motor assembly includes a pump-motor that maintains a minimum pressure of a liquid coolant in a liquid coolant system that cools the back-up energy storage unit, and a housing that is completely enclosed, the housing containing the pump-motor, and having a removable access panel on one side thereof the enclosed structure, and an opening on another side thereof to the storage container.

Pump-motor assembly for an energy storage system

A thermal management system for an energy storage container includes an enclosed compartment containing an energy storage unit, an air temperature control unit configured to cool an interior of the enclosed compartment, and at least one inverter connected to a coolant circuit, which is separate from the air temperature control unit, and configured to be cooled by a coolant in the coolant circuit. The thermal management system also includes a radiator located outside of the enclosed compartment, the radiator being connected to the coolant circuit, wherein the coolant in the coolant circuit flows through the radiator, and at least one fan located alongside the radiator, outside of the enclosed compartment, the at least one fan being configured to blow air across the radiator to cool the coolant flowing through the radiator.

Tube

In one aspect, a thermal management system includes a first coolant circuit, through which a first coolant circulates, and including at least a radiator for cooling the first coolant, a storage containing one or more power electronics, a heat exchanger, and a thermostatic valve that outputs the first coolant to at least one of the storage containing the one or more power electronics and the heat exchanger. A second coolant circuit, through which a second coolant circulates, includes the heat exchanger configured to cool the second coolant using the first coolant, an energy storage unit cooled by the second coolant, and a refrigeration unit configured to cool the second coolant. A coolant temperature sensor outputs a temperature of the coolant in the second coolant circuit, and a controller controls at least the refrigeration unit based on the temperature of the coolant output by the coolant temperature sensor.

An air-to-air aftercooler (ATAAC) configured to cool compressed air from an air compressor is disclosed. The ATAAC may comprise a header at a cold end, and a plurality of core tubes. Each of the core tubes may have a first end and a second end. The ATAAC may further comprise a plurality of grommets each connecting the second end of one of the core tubes to a slot of the header. Each of the grommets may include an inner surface contacting the core tube and an outer surface contacting the slot of the header. The inner surface of the grommet may include radially-inwardly projecting regions contacting the core tube, and depressed regions providing clearance between the grommet and the core tube.

Tube-to-header slip joint for air-to-air aftercooler

The invention relates to an ATAAC having a header, a plurality of slots defined in the header, a plurality of core tubes coupled to the header, and a plurality of joint assemblies to couple the header with the plurality of core tubes. Each of the plurality of joint assemblies includes an adapter, a sleeve, and a nut. The adapter further includes a first section threadedly engaged with one of the plurality of slots. The adapter further includes a tapered section inserted inside a flared end portion of one of the plurality of core tubes. Furthermore, the adapter includes a second section defined between the tapered section and the first section. The sleeve disposed around the one of the plurality of core tubes, the sleeve is engaged with the flared end portion of the one of the plurality of core tubes. The nut is engaged with the sleeve and the second section of the adapter.
