Abstract

The invention relates to a protective cap used for protecting a heat-conducting glue on a radiator provided with radiating ribs. The protective cap comprises an outer frame and a top formed at the middle part of the outer frame. The top of the protective cap corresponds to the radiator top coated with the heat-conducting glue, and is arranged above the heat-conducting glue in a covering manner; the outer frame is fixed around the radiator top; the outer frame is attached to the top surface of the radiator around the heat-conducting glue so as to isolate inner space in the top of the protective cap and clearances among the radiating ribs. A frame body of the protective cap covers the top surface of the radiator around the heat-conducting glue correspondingly so as to isolate the inner space in the top of the protective cap and the clearances among the radiating ribs, so that impurities in the air around the radiator cannot disseminate around the radiator top through the clearances to contact and pollute the heat-conducting glue, and the heat-conducting glue can be effectively protected from being polluted.
