Abstract:
1. A performance testing apparatus for a heat pipe comprising: an immovable portion having a cooling structure defined therein for cooling a heat pipe requiring testing; a movable portion capable of moving relative to the immovable portion and having a cooling structure defined therein for cooling the heat pipe; a receiving structure being located between the immovable portion and the movable portion for receiving the heat pipe therein; and at least one 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; wherein the receiving structure is a channel defined between the immovable portion and the movable portion; wherein the at least a temperature sensor has a detecting portion thereof exposed to the channel; wherein at least one of the immovable portion and the movable portion has at least one positioning structure communicating with the channel, the at least one temperature sensor being positioned in the at least one positioning structure; wherein the at least a temperature sensor comprises two wires, each of the two wires comprising first and second sections and a working section between the first and second sections, the working section being the detecting portion of the at least a temperature sensor; wherein the at least one positioning structure of one of the immovable portion and the movable portion defines two pairs of through holes therein, and wherein each of the two wires has the first section thereof extending in one of the through holes, the second section fitted in another through hole, and the working section located at a bottom of the positioning structure for contacting with the heat pipe, and wherein an end of the second section extends away from the another through hole for connecting with a monitoring computer; and wherein the cooling structure of the immovable portion comprises an inlet and an outlet at one end of the immovable portion to allow coolant circulation into or out of the immovable portion.
