A gas-liquid delivery connector, a gas-liquid delivery connector pair, and a gas-liquid delivery device. The gas-liquid delivery connector comprises: a male connector (1) for connecting a catheter, wherein the male connector (1) is provided with a first connecting channel (11) in the axial direction thereof; and a female connector (2) for connecting a microcatheter, wherein the female connector (2) is provided with a second connecting channel (21) in the axial direction thereof. The female connector (2) is connected to the male connector (1) such that the second connecting channel (21) is in butt joint with and in communication with the first connecting channel (11), and the inner diameter of the second connecting channel (21) is the same as the inner diameter of the first connecting channel (11).

A coupler (R) female element (4) able to be coupled with a male element (2) for the removable fluid junction of two pipes. The female element body (20) centered on a first longitudinal central axis (X20) with an inner volume (V20) for receiving the male element. Additionally, the female element has a central plunger (44) longitudinally secured to the body and positioned within the inner volume, with a slide valve (46) movable within the inner volume around the central plunger between a forward closing position, in which the slide valve (46) cooperates tightly with the body (20) and the central plunger (44), and a withdrawn open position. The female element body (20) including an outer flange ring (22) positioned around the inner volume and having an outer radial surface. The outer flange ring has at least two passages (32), each passage being arranged through the outer flange ring and linking the outer radial surface and the inner volume.

A heat pipe, a heat pipe assembly and a method for assembling the heat pipe assembly. The heat pipe includes a main body part and an insertion part. The insertion part is connected to the main body part. The main body part and the insertion part together form a single hollow pipe. The insertion part has an outer surface and at least one recessed part formed on the outer surface.
