Performance testing apparatus for heat pipes

A performance testing apparatus for a heat pipe comprising:

• an immovable portion having a cooling structure defined therein for cooling the heat pipe requiring test;
• a movable portion capable of moving relative to the immovable portion;
• a receiving structure being located between the immovable portion and the movable portion for receiving the heat pipe therein;
• a positioning structure extending from at least one of the immovable portion and the movable portion for avoiding the movable portion from deviating from the immovable portion during movement of the movable portion relative the immovable portion to ensure the receiving structure being capable of precisely receiving the heat pipe;
• at least a temperature sensor being attached to at least one of the immovable portion and the movable portion for thermally contacting the heat pipe in the receiving structure for detecting temperature of the heat pipe;
• and
• an enclosure enclosing the immovable portion and the movable portions therein, and defining a space for movement of the movable portion relative to the immovable portion;
• wherein the enclosure has a bottom thereof extending a plurality of ribs supporting the immovable portion thereon.
