A liquid cooling structure for a server with low-force quickseal joints to carry the coolant includes a first support, a first joint, a second support, a second joint, a first magnet, and a second magnet. The first support is set on the cabinet body. The second support is set on the server body. The first joint is set on the first support. The second joint is arranged on the second support and can be coupled with the first joint. The first magnet is set on first support. The second magnet is set on second support. The first magnet and second magnet with opposite magnetism attract each other to reduce the amount of force required for coupling the first joint and the second joint, and is labor-saving.
