1. A coolant distribution unit (CDU), comprising:
a loop inlet element and a loop outlet element, disposed adjacent to each other and in communication with a coolant loop;
a fixed component; and
a hot-swappable pump unit (HSPU) configured to connect to the coolant loop along a matching direction, wherein the hot-swappable pump unit (HSPU) comprises:
a housing comprising an accommodation space and a first lateral wall, wherein the loop inlet element and the loop outlet element are disposed on a backplate opposite to the first lateral wall, and the fixed component is arranged between the first lateral wall and the backplate;
a pump accommodated within the accommodation space;
a pump inlet element in communication with the pump by passing through the first lateral wall and configured to connect to the loop outlet element along the matching direction;
a pump outlet element in communication with the pump by passing through the first lateral wall and configured to connect to the loop inlet element along the matching direction; and
a fastening component disposed in the housing and configured to pass through the first lateral wall to engage with the fixed component, wherein when the fastening component and the fixed component are engaged with each other, the housing is driven to move along the matching direction, so that the pump inlet element and the loop outlet element are connected and matched, and the pump outlet element and the loop inlet element are connected and matched.
