FIELD OF THE INVENTION

The present invention relates generally to the testing method and construction of a heat conductor, and more particularly to an innovative design that a heat conductor includes a micro detection element for rapid detection of the vacuum state.

BACKGROUND OF THE INVENTION

To ensure a better heat conduction effect, a heat conductor is generally fitted with an opening at one side for vacuum pumping. After that, it is required to keep the vacuum constant by sealing this preset opening. However, defective products shall be screened via a testing method since the vacuum state of finished products cannot be identified apparently after sealing of opening. According to existing testing methods, the finished heat conductor shall be continuously warmed up after vacuum pumping & sealing, i.e. seasoning, thereby promoting the reliability and stabilizing the quality of heat conductor. Once upon cooling down, one side of the heat conductor is heated up (e.g. soaked in thermal fluid), while the heat conduction speed is tested at the other side. In the presence of abnormally slow speed or excessive temperature difference for both sides, they are proved non-conforming products below a vacuum state. Based on practical experience of testing methods for the conventional heat conductor, it can be learnt that, the process of testing one side's heat conduction via heating of the other side must wait for identification of vacuum state by heat transfer from one side to the other side, thus leading to a time-consuming operation. And, the testing time will be obviously prolonged with the increasing length of heat conductors to be tested, offering a lower availability for this industry.

Thus, to overcome the aforementioned problems of the prior art heat conductor, it would be an advancement in the art to provide an improved one that can speed up the testing process.

To this end, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.

BRIEF SUMMARY OF THE INVENTION

Based on this innovative design that heat conductor of the present invention is detected by an injecting micro detection element, it is possible to improve a time-consuming and slow testing process of testing one side's heat conduction via heating of the other side. In the present invention, only a detector is required to detect if there is any leakage of micro detection element from exterior of heat conductor, thereby facilitating the detection of any leakage, and promoting considerably the testing efficiency in a cost-effective manner to meet the industrial requirement for a higher availability.
