Definitions

  • the disclosure generally relates to a heat transfer apparatus, and more particularly to a heat pipe for removing heat from heat generating components.
  • FIG. 1 is a longitudinal, cross-sectional view of a heat pipe according to an embodiment of the present disclosure.
  • FIG. 2 is an isometric view of a second pipe of the heat pipe of FIG. 1 .
  • FIG. 3 is a transverse, cross-sectional view of the second pipe of FIG. 2 .
  • FIG. 4 is a transverse, cross-sectional view of a mandrel used in a method for manufacturing a heat pipe according to an embodiment of the present disclosure.
  • the heat pipe 100 includes a first pipe 10 and a second pipe 20 enclosing an end of the first pipe 10 .
  • the first pipe 10 includes a casing 13 , a continuous first wick structure 12 attached to an inner wall of the casing 13 , and working fluid contained in the casing 13 .
  • the casing 13 is a metallic, hollow, elongated tube having an annular transverse cross section and a uniform thickness along a longitudinal direction thereof. Opposite ends of the casing 13 are sealed.
  • the first wick structure 12 is evenly distributed around the inner wall of the casing 13 and extends along the longitudinal direction thereof.
  • the first wick structure 12 is tube-shaped in profile, and usually selected from a porous structure such as grooves, sintered powder, screen mesh, or bundles of fiber, which enables it to provide a capillary force to drive condensed working fluid to flow back.
  • An inner periphery of the first wick structure 12 defines a chamber 11 therein to allow vaporized working fluid flowing therethrough.
  • the first pipe 10 includes an evaporator section 15 disposed at an end thereof and a condenser section 17 disposed at the other end thereof along the longitudinal direction thereof.
  • a length of the condenser section 17 along the longitudinal direction of the casing 13 is larger than that of the evaporator section 15 .
  • the second pipe 20 is elongated and encloses the condenser 17 of the first pipe 10 therein.
  • the second pipe 20 includes a casing 22 , a plurality of second wick structure 21 attached to an inner wall of the casing 22 , and working fluid contained in the casing 22 .
  • the casing 22 is a metallic, hollow tube having an annular transverse cross section and a uniform thickness along a longitudinal direction thereof. One end of the casing 22 is closed and the other end of the casing 22 along the longitudinal direction of the casing 22 is open.
  • the second wick structures 21 are spaced from each other and evenly distributed around the inner wall of the casing 22 .
  • the second wick structures 21 are made of sintered powder, such as copper powder or other suitable material.
  • Each second wick structure 21 is an elongated strip and extends from the open end to the closed end of the casing 22 along a longitudinal direction of the casing 22 .
  • a transverse cross section of each second wick structure 21 is trapezoidal.
  • Each second wick structure 21 has a convex outer end attached to the inner wall of the casing 22 , and a concave inner end opposite to the outer end and attached to an outer wall of the condenser section 17 of the casing 13 of the first pipe 10 .
  • each second wick structure 21 decreases from the outer end to the inner end.
  • An elongated channel 23 is defined between each two adjacent second wick structures 21 to allow vaporized working fluid flow therethrough.
  • each elongated channel 23 is defined among the inner wall of the casing 22 , the outer wall of the casing 13 of the first pipe 10 , and side surfaces of two adjacent second wick structures 21 .
  • the inner ends of the second wick structures 21 define a receiving chamber 24 therebetween to receive the condenser section 17 of the first pipe 10 therein.
  • a bore diameter of the receiving chamber 24 is equal to a diameter of the condenser section 17 of the first pipe 10 .
  • the condenser section 17 of the first pipe 10 is received in the receiving chamber 24 and an outer periphery thereof intimately contacts the inner ends of the second wick structures 21 . An edge of the opened end is shrunken and sealed to an outer wall of the evaporator section 15 of the first pipe 10 .
  • the condenser section 17 and the second pipe 20 cooperatively form a condensing portion of the heat pipe 100
  • the evaporator section 15 of the first pipe 10 acts as an evaporating portion of the heat pipe 100 .
  • the heat pipe 100 When the heat pipe 100 is used, heat generated from heat generating components is absorbed by the evaporator section 15 and then transfers to the condenser 17 and the second pipe 20 to dissipate.
  • Q shows an average of heat transfer rates
  • C shows a specific heat
  • ⁇ T shows an varied temperature
  • M shows a mass
  • the condensing portion of the heat pipe 100 is formed by the condenser section 17 and the second pipe 20 , so the mass of the heat pipe 100 is larger than a conventional heat pipe formed by a single tube such as first pipe 15 , and so the average of heat transfer rates of the heat pipe 100 is improved.
  • the heat pipe 100 is manufactured by following steps:
  • the mandrel 30 includes a cylindrical main body 31 and a plurality of extending portions 33 radially extending from an outer periphery of the main body 31 and evenly spaced from each other.
  • Each extending portion 33 is an elongated strip and extends along a longitudinal direction of the main body 31 .
  • a receiving space 35 is defined between each two adjacent extending portions 33 . Outer ends of the extending portions 33 abut the inner wall of the casing 22 .
