Definitions

  • the present invention relates to an isothermal plate assembly with predetermined shape and method for manufacturing the same, and more particularly to an isothermal plate assembly with predetermined shape and manufactured by low cost and high yield process.
  • the conventional isothermal plate for heat-dissipating device of electronic apparatus is manufactured by a high thermally conductive material.
  • the thermally conductive material is manufactured into a flat plate with a hollow accommodation space defined therein and containing wicked structure.
  • the isothermal plate further comprises a wavy supporting unit arranged in the hollow accommodation space and used to support walls between an upper plate and a lower plate. The isothermal plate is then filled with working fluid and the accommodation space is sealed.
  • the isothermal plate described in above-mentioned process can only form plate-like structure because the conventional isothermal plate adopts non-vacuum structure.
  • the conventional isothermal plate has crack problem when it is bent from flat state or its shape is varied due to temperature change. The yield of the conventional isothermal plate is degraded.
  • the electronic apparatus are arranged on one side of the isothermal plate, and the heat-dissipating fins are arranged on another side of the isothermal plate. The heat-dissipating device is difficult to be made compact and the heat-dissipating effect is influenced.
  • the present invention is to provide an isothermal plate assembly with predetermined shape and manufactured by low cost and high yield process, thus meeting requirements of various electronic apparatus.
  • the present invention provides a manufacturing method for an isothermal plate assembly.
  • An upper plate and a lower plate with predetermined shape are provided and an accommodation space is defined therein.
  • a flattened heat pipe is bent into the predetermined shape and placed into the accommodation space.
  • a binding agent is applied on the face between the heat pipe, the upper plate and the lower plate.
  • the upper plate and the lower plate are assembled and then a hot melting process is executed.
  • the resultant product is then cooled to form a finished isothermal plate assembly with predetermined shape.
  • the present invention provides an isothermal plate assembly with predetermined shape, which comprises an upper plate, a lower plate opposite to the upper plate and an accommodation space defined between the upper plate and the lower plate.
  • the upper plate and the lower plate are bent into a predetermined shape.
  • a heat pipe is bent to the predetermined shape and placed into the accommodation space.
  • Fig. 1 shows the flowchart of method for manufacturing the isothermal plate assembly 1 according to a preferred embodiment of the present invention, which comprises following steps:
  • the heat pipe 2 can be firstly subjected to flatten process and then bent according to the shape of the upper plate 11 and the lower plate 12.
  • the isothermal plate assembly can be made with various shapes.
  • the isothermal plate assembly is formed by assembling the upper plate 11 and the lower plate 12.
  • the upper plate 11 and the lower plate 12 are preformed with predetermined bending shape.
  • the heat pipe 2 also has corresponding bending shape and is placed between the upper plate 11 and the lower plate 12 for providing heat conduction. Therefore, the isothermal plate with multiple and various shapes can be made with simple and low cost process.
  • the isothermal plate with multiple shapes can be easily adapted with various electronic devices.
  • the above-mentioned steps 102, 104 and 106 are interchangeable. That is, the heat pipe 2, the upper plate 11 and the lower plate 12 are bent before the heat pipe 2 is placed into the accommodation space 113 formed between the upper plate 11 and the lower plate 12. Alternatively, the heat pipe 2 is firstly placed into the accommodation space 113 formed between the upper plate 11 and the lower plate 12 and then bent together with the upper plate 11 and the lower plate 12. Moreover, a binding agent is selectively applied to contact faces between the heat pipe 2 and the upper plate 11 (and the lower plate 12). The binding agent fills the gap between the heat pipe 2 and the upper plate 11 (and the lower plate 12) by a following-up heating process.
  • step 106 the step of applying binding agent to contact faces between the heat pipe 2 and the upper plate 11 (and the lower plate 12) can be eliminated if the hermetic degree between the heat pipe 2 and the upper plate 11 (and the lower plate 12) is sufficient.
  • the step of applying binding agent to contact faces between the upper plate 11 and the lower plate 12 can also be eliminated.
  • the end product is manufactured in the step 108, wherein the upper plate 11 and the lower plate 12 are assembled. The high temperature heating process can be eliminated.
  • the isothermal plate assembly with multiple shapes comprises an upper plate 11, a lower plate 12 and flattened heat pipe 2 between the upper plate 11 and the lower plate 12.
  • the upper plate 11 and the lower plate 12 are used form a closed isothermal plate assembly 1 and define an accommodation space 13 therein for receiving the flattened heat pipe 2.
  • at least one dent 14 is defined on either the upper plate 11 or the lower plate 12.
  • the upper plate 11 or the lower plate 12 with the dent 14 is assembled with the lower plate 12 or the upper plate 11 with smooth face to form an isothermal plate 1 with the accommodation space 13, as shown in Fig. 3.
  • both the upper plate 11 and the lower plate 12 are provided with dents 14, 14' to define the accommodation space 13 when the upper plate 11 and the lower plate 12 are assembled together.
  • the upper plate 11 and the lower plate 12 provided with dent 14, 14' are assembled by the help of outer coupling plates 111 and 121.
  • the accommodation space 13 is defined by the dents provided by the upper plate 11 and the lower plate 12.
  • the upper plate 11 and the lower plate 12 can be subjected to bending operation of other shape before assembling into the isothermal plate 1.
  • the shape is, for example, L shape in Fig. 2, U shape in Fig. 6 or S shape in Fig. 7.
  • the heat pipe 2 is placed in the accommodation space 13 defined by the dents provided by the upper plate 11 and the lower plate 12 and is functioned to provide heat conduction.
  • the heat pipe 2 is flattened to increase a contact surface between the upper plate 11 and the lower plate 12 and can be bent according to the shape of the upper plate 11 and the lower plate 12. Therefore, the heat pipe 2 has shape corresponding to the shape of the accommodation space 13 between the upper plate 11 and the lower plate 12.
  • the heat pipe 2 can be easily assembled into the accommodation space 13, as shown in Figs. 2 to 5.
