Abstract
Additional cooling is provided to an energy storage module of a cooling system with a plurality of cooling channels in contact with a surface of an energy storage device, by pipe connections of a common cooling fluid outlet pipe that have a lower melting point than pipe connections of the common cooling fluid inlet pipe. In use, if the pipe connections are subjected to elevated temperatures, or fire, the pipe connections of the common fluid outlet pipe fail before the pipe connections of the common fluid inlet pipe, causing a pressure drop, whereby the rate of fluid flow through the cooler of the energy storage module in which the pipe connection has failed is substantially increased.
Claims16
An energy storage module cooling system for a power supply system comprising one or more energy storage modules arranged in parallel;
- the cooling system comprising:
- a cooling unit comprising a cooling fluid reservoir,
- a common cooling fluid inlet pipe and a common cooling fluid outlet pipe;
- wherein each energy storage module comprises one or more energy storage devices;
- and for each energy storage device, a cooler in contact with the energy storage device;
- wherein the cooler comprises one or more cooling fluid channels for circulating cooling fluid, the channels being in contact with a surface of the energy storage device, each cooling fluid channel being adapted to receive cooling fluid, extract heat from the energy storage device and return the cooling fluid to the cooling unit;
- and wherein the common cooling fluid inlet pipe and common fluid outlet pipe comprise pipe connections between each energy storage device cooler;
- wherein the pipe connections of the common cooling fluid outlet pipe have a lower melting point than pipe connections of the common cooling fluid inlet pipe.
