[0037] The aforementioned receiving groove 10 is formed on the side surface of the horizontal portion 31 of the L-shaped movable block 3 facing the inner wall of the slide groove 8.

[0038] Working principle:

[0039] During use, the opposite ends of the inner sleeve and outer sleeve are connected to the liquid supply circuit and the liquid cooling circuit, respectively.

[0040] When the inner and outer sleeves separate:

[0041] The floating block inside the inner sleeve moves to the lower end of the inner sleeve under the action of the return spring and seals with the inner sleeve to seal the flow channel inside the inner sleeve. The floating ring inside the outer sleeve moves to the upper end of the support rod under the action of the return spring and seals with the outer sleeve and the support rod respectively to seal the flow channel inside the outer sleeve. The vertical part of the L-shaped movable block moves away from the outer sleeve under the action of the first elastic element, so that the inner convex part on it is located at the innermost end of its stroke.

[0042] When the outer sleeve and inner sleeve are to be inserted into each other:

[0043] The inner sleeve moves downward and enters the outer sleeve. The downward movement of the inner sleeve pushes the floating ring in the outer sleeve to move downward and compress the return spring. The floating block in the inner sleeve moves upward relative to the inner sleeve under the push of the fixed support rod upper end face and compresses the return spring. At this time, the flow channels in the inner and outer sleeves are connected and interconnected.

[0044] As the inner sleeve moves downward, the outer protrusion on the inner sleeve moves until its lower end face contacts the upper end face of the inner protrusion on the L-shaped movable block; the outer protrusion continues to move downward with the inner sleeve, while pushing the horizontal part of the L-shaped movable block, which can only move radially, to move outward, so that the vertical part of the L-shaped movable block moves towards the outer sleeve and squeezes the first elastic element.

[0045] When the outer protrusion on the inner sleeve moves below the inner protrusion on the L-shaped movable block, the vertical part of the L-shaped movable block loses the restriction of the outer protrusion on the inner sleeve and resets inward under the action of the first elastic element, thereby allowing the lower end face of the inner protrusion on the L-shaped movable block to overlap with the upper end face of the outer protrusion on the inner sleeve to stop the inner sleeve.

[0046] When it is necessary to separate the connected outer sleeve and inner sleeve again:

[0047] The vertical part of the L-shaped movable block needs to be pushed towards the outer sleeve so that the inner convex part on the horizontal part of the L-shaped movable block moves outward and exits the area above the outer convex part on the inner sleeve. The inner sleeve, which has lost its stop position, moves upward under the action of the return spring, so that the inner sleeve can be pulled out from the outer sleeve. Then, the vertical part of the L-shaped movable block is released so that the inner convex part on the horizontal part of the L-shaped movable block returns to the innermost end of its stroke under the action of the first elastic element.

[0048] After the return springs in the outer sleeve and inner sleeve lose their compressive force, they reset. Under the action of the reset spring, the floating block in the inner sleeve moves back to the lower end of the inner sleeve and seals with the inner sleeve to seal the flow channel inside the inner sleeve. Under the action of the reset spring, the floating ring in the outer sleeve moves back to the upper end of the support rod and seals with the outer sleeve and support rod respectively to seal the flow channel inside the outer sleeve.

[0049] During the reciprocating insertion and separation process of the outer sleeve and inner sleeve, the horizontal part of the L-shaped movable block reciprocates within the receiving groove of the outer sleeve, allowing the inner convex part to move radially inward and outward. During this process, the pin block and the second elastic element provided between the two side surfaces of the horizontal part of the L-shaped movable block and the inner wall of the slide groove provide precise guidance for the horizontal part of the L-shaped movable block, preventing it from shifting its position. Furthermore, both the pin block and the second elastic element can be easily and quickly assembled inside the outer sleeve, avoiding the risks caused by exposed small parts in complex usage environments and improving the convenience and safety of use.

[0050] When using the above-mentioned liquid-cooled heat dissipation unit, after the inner and outer sleeves are plugged in, the liquid supply circuit and the liquid cooling circuit are connected. This not only facilitates the assembly of each component and ensures the stability of the connection between the components, but also avoids the risks caused by the exposure of small components in complex use environments, thus improving the convenience and safety of use.

[0051] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
