Visual and thermal image recognition based PHM technique for wellsite

A technique facilitates removal of heat. The technique involves moving a process fluid through a buffer tank which is combined with a heat exchange system. The heat exchange system includes a conduit carrying a coolant fluid which removes excess heat from a heat source. The conduit is routed to the buffer tank so that the cooler process fluid moving through the buffer tank is able to remove heat from the coolant fluid before it is routed back to the heat source for continued heat removal. In a well application, for example, a heat source, e.g. an electric motor, may be located on a transport vehicle and cooled by the coolant fluid. The heat transferred to the coolant fluid from the heat source is removed by routing the coolant fluid through the conduit associated with the buffer tank. This enables the cooler process fluid in the buffer tank to be used in lowering the temperature of the coolant fluid.
