Abstract
A heat pipe with micro tubes includes of a solid heat conductor provided therein with two or more parallel micro tubes. The micro tubes are filled with a working medium which exchanges heat through phase change. Two ends of the heat conductor are sealed and at least one of the ends is provided with a sealing strip of gradually shrinking shape that is formed from cold welding.
Claims19
A heat pipe with micro tube arrays, the heat pipe comprising:
- a solid heat conductor having an integral structure including a first end and a second end opposite the first end, wherein the solid heat conductor forms an integral plane;
- two or more parallel through micro tubes within the solid heat conductor, each of the micro tubes comprising:
- a working medium that is operable to exchange heat through phase change;
- a sealed end at the first end of the solid heat conductor, the sealed end closing each of the two or more parallel through micro tubes from communication with each other at the sealed end,
- the two or more parallel through micro tubes are sealed from communication with each other at the second end of the solid heat conductor to form another sealed end;
- the first end and the second end of the solid heat conductor comprising upper walls and lower walls of the micro tubes,
- two outer side walls of two side micro tubes of the two or more parallel micro tubes are located at two sides of the solid heat conductor;
- midwalls separating every two adjacent micro tubes, wherein neighboring micro tubes share a common midwall;
- a sealing strip forms the sealed end of each solid heat conductor with the two or more parallel through micro tubes and comprising first and second curved surfaces that converge with each other towards a same direction of a length of the solid heat conductor to form a tip line in the first end and the second end of the solid heat conductor, and forms a deformation with a thickness between the two curved surfaces gradually and continuously decreases along the direction of a length of the solid heat conductor having a material of the upper walls, lower walls and midwalls that is deformed from portions of the upper and lower walls, portions of the outer side walls, and portions of the midwalls;
- wherein one solid strip is provided within each end of the solid heat conductor and extends in a direction parallel to a length direction of the micro tubes.
