Charge air cooler for fuel engine

A charge air cooler for a fuel engine comprising:

• a casing having an inlet and an outlet,
• a heat exchanger within the casing between the inlet and the outlet,
• a thermally responsive draining mechanism for draining condensates,
• the draining mechanism being configured to drain condensates when a temperature within the charge air cooler is below a defined temperature,
• the draining mechanism comprising a drain port,
• a valve arranged on the drain port,
• an actuation device for moving the valve between an opened state and a closed state,
• wherein the actuation device includes a phase change material,
• wherein the valve is in the opened state when the phase change material is a first phase and the valve is in the closed state when the phase change material is in a second phase, and wherein the phase change material changes phase at a temperature above 1° Celsius,
• wherein the actuation device comprises a spring element, biasing the valve toward the opened state, and a deformable container filled with the phase change material that pushes the valve to the closed state when the phase change material is in the second phase,
• wherein the deformable container comprises a capsule linked with a diaphragm by a tube, the diaphragm is configured to push the valve to the closed state when the phase change material is in the second phase.
