An air pump assembly (10) and a refrigeration device. The air pump assembly (10) comprises: a seal box (200) comprising a lower box body (210) with an opened upper side, and an upper box body (220) with an opened lower side, the upper box body (220) tightly covering the upper side of the lower box body (210) to define a sealed space with the lower box body (210); an air pump (300) provided in the sealed space of the seal box (200), an air inlet pipe (301) and an air outlet pipe (302) of the air pump (300) both extending upwards; and an air inlet connecting pipe (310) and an air outlet connecting pipe (320) embedded in the upper box body (220) and both extending in the up-down direction, the air inlet connecting pipe (310) being located above the air inlet pipe (301) and sleeved on the air inlet pipe (301), and the air outlet connecting pipe (320) being located above the air outlet pipe (302) and sleeved on the air outlet pipe (302). The air pump assembly (10) can reduce outward propagation of noise in operation of the air pump (300), and can facilitate dismounting the upper box body (220) onto the lower box body (210).
