Abstract

A cooling system is provided that includes a cap secured to a degas bottle. A filter that includes a frangible area is arranged within the degas bottle near the cap to separate the degas bottle into first and second sides. The frangible area is breakable in response to a predetermined pressure differential to provide an opening in the filter and connect the first and second sides. The filter includes a housing that supports mesh which filters debris and prevents the debris from reaching a valve in the cap. The opening in the broken frangible area bypasses the mesh in the event the mesh becomes clogged with debris. In operation, the inventive filter provides a simple method of releasing pressure in the cooling system. A wall of the filter is fractured once the differential pressure reaches the predetermined differential pressure. The inexpensive filter can then be replaced.
