Description

Technical Field

[0001] The utility model relates to the field of end covers, in particular to an inlet and outlet end cover. Background Art

[0002] The end covers are the inlet and outlet end covers and the return water end covers. As a circulating water chamber, water barriers are set according to the designed water flow number. Bolts are installed between the end covers and the shell to fasten them. End covers are particularly widely used. Air coolers also need to use inlet and outlet end covers. The inlet and outlet end covers are one of the main accessories of air coolers.

[0003] At present, a Chinese patent with announcement number CN219103813U discloses an inlet and outlet end cover, including a composite inlet and outlet end cover body, an air cooler body and a sealing rubber pad. The composite inlet and outlet end cover body is arranged at the front end of the air cooler body, and a water inlet plug-in tube and a water outlet plug-in tube are installed on the composite inlet and outlet end cover body. The utility model installs the water inlet plug-in tube and the water outlet plug-in tube on the inlet and outlet end cover body, and installs a sealing rubber pad in one end of the water inlet plug-in tube connected to the cooling water pipe rack in the air cooler. However, when the composite inlet and outlet end cover body in the above patent is installed on the front end of the air cooler body, it does not have a corresponding sealing structure, which easily leads to leakage at the connection between the two, thereby affecting the sealing effect of the composite inlet and outlet end cover body on the air cooler body. For this reason, we propose an inlet and outlet end cover to solve the above problem. Utility Model Content
