The invention provides a shrinking tube mold and a heat pipe, and the shrinking tube mold is used for shrinking the heat pipe. The shrink tube mold includes: a fixed mold with a first end and a second end oppositely arranged, the first end is provided with a first counterbore, the second end is provided with a second counterbore, and the second counterbore and the first counterbore pass through the first counterbore. A passage communicates; a mold core fixed in the first counterbore, the mold core is provided with a second passage which communicates with the first passage and whose diameter gradually decreases along the direction from the first end to the second end; the guide fixed in the fixed mold Positive pin, the pilot pin includes the first segment, the second segment and the third segment whose diameter increases sequentially along the direction from the first end to the second end, a part of the first segment is located in the second channel, and the rest of the first segment Located within the first channel, the second section located within the first channel, and the third section located at least partially within the second counterbore; wherein the first counterbore, the second counterbore, the first channel, and the second channel are located along the first end The axes pointing in the direction of the second end are collinear.
Description
【Technical field】 [0001] The invention relates to the technical field of heat dissipation, in particular to a tube shrinking die and a heat pipe. 【Background technique】 [0002] With the development of electronic and electrical technology and the improvement of user needs, various electronic products in daily life, scientific research and education have more and more functions and higher power, and the heating of electronic products is becoming more and more serious. And heat pipe is an ideal solution to solve the heat dissipation problem of various electronic products. Since the heat pipe has the characteristics of simple manufacturing process and low production cost compared with the vapor chamber, most electronic products still choose the heat pipe as the main heat dissipation element. However, in the prior art, as the thickness of the heat pipe wall decreases, it becomes more and more difficult to shrink the heat pipe; at the same time, because the length of the invalid...
