Claim:
1. A receiver for a heat exchanger comprising: a first receiver body defining a first passageway and a second passageway in condition that one of the first passageway and the second passageway acts as an inlet hole, and the remaining one of the first passageway and the second passageway acts as an outlet hole, the second passageway comprising a main body portion and a buffer space in communication with the main body portion; and a filter element covering the buffer space so as to filter the second passageway; wherein the buffer space is empty and comprises a first end opening directly covered by the filter element and a second end opening in communication with the main body portion; and wherein an area encircled by the first end opening of the buffer space is larger than a horizontal cross-sectional area of the main body portion adjacent to the buffer space, as a result that a relatively large filter interface can be achieved; and wherein the second passageway comprises a counter bore portion, the counter bore portion comprising the buffer space, an accommodating hole above and in communication with the buffer space and a positioning hole above and in communication with the accommodating hole, the filter element being received in the accommodating hole, the receiver further comprising a retaining plate at least partly received in the positioning hole, the buffer space being provided with a reasonable large thickness so as to perform a buffering function when a refrigerant flows through the second passageway.
