'kühlen' and 'abkühlen' can both mean that something becomes colder or is made colder. The most important difference is: 'kühlen' often emphasizes the active action. Someone makes something cold or keeps it cool. 'abkühlen' can also happen without an active person: the soup is sitting on the table and gets cooler by itself. When referring to your own body, 'sich kühlen' and 'sich abkühlen' are very similar. Learners can easily confuse the words because both have to do with a lower temperature. As a guide: 'kühlen' sounds more active, while 'abkühlen' often describes the process or the result.
