In order to solve the wear problem of the rotor in refrigerant pump of cooling system in data center,a new rolling rotor profile is designed,and a rolling internal rotor pump is formed by engaging the roller with the inner rotor and the outer rotor.The construction of the rolling rotor profile is studied,and the displacement formula of the re-frigerant pump is derived.The influence of roller radius,wrap angle and eccentricity on the geometrical structure of the rolling rotor,the displacement of the refrigerant pump and the stress of the rolling rotor are analyzed.The results show that with the increase of the roller radius,the displacement of the refrigerant pump decreases slightly and the max-imum stress on the rolling rotor decreases first and then increases.With the increase of the wrap angle,the maximum stress on the rolling rotor increases gradu-ally.With the in-crease of eccentricity,the displacement of the refrigerant pump increases gradually,while the maximum stress on the rolling rotor increases gradually.
