1. Field of the Invention
The present invention relates to a temperature sensing apparatus with flexible contact, especially to a temperature sensing apparatus used to examine straight heat pipes and curved heat pipes.
2. Description of Prior Art
The conventional heat pipe needs examination for heat conduction amount after a batch of heat pipes are manufactured. However, the conventional examination instruments or equipments are expensive and the operation thereof is cumbersome and time consuming. Therefore, the examination of heat pipe is conducted in sampling fashion instead of entire examination. Certain amount of heat pipes are sampled for inspection to estimate the yield for one batch.
However, all of the heat pipes are not straight pipe during examination. Some of them might be curved pipe for specific applications.
The present invention is to provide a temperature sensing apparatus with flexible contact for heat pipe, which can be used for both straight heat pipes and curved heat pipes.
Accordingly, the present invention provides a temperature sensing apparatus with flexible contact. The temperature sensing apparatus comprises a rod-shaped body, a temperature-sensing head elastically arranged at one end of the body and a clamping rod transversely locked to the body. The temperature-sensing head is connected to a temperature-sensing wire. Another end of the clamping rod is defined with a locking section such that the clamping rod can be connected to a heat-pipe temperature sensing apparatus. Both straight heat pipe and curved heat pipe can be examined by the temperature sensing apparatus with flexible contact.
The features of the invention believed to be novel are set forth with particularity in the appended claims. The invention itself however may be best understood by reference to the following detailed description of the invention, which describes certain exemplary embodiments of the invention, taken in conjunction with the accompanying drawings in which:
With reference to
The body 50 is of rod-shaped and provides a supporting structure. The body 50 comprises a transverse hole 500 and one end of the clamping rod 54 is inserted into the transverse hole 500 such that the body has lateral movement. A bolt 501 is used to lock the clamping rod 54. Another end of the clamping rod 54 is defined with a locking section, which is a through hole 540. The pushing unit 30 of the clamping unit 3 has lateral movement in the through hole 540 and is clamped by a bolt 541. The temperature-sensing head 51 is made of thermal-isolation material such as plastics or bakelite and is connected to a temperature sensing wire 53. The temperature sensing wire 53 can be fixed to the temperature-sensing head 51 by glue. A spring element 52 is connected between the temperature-sensing head 51 and an end of the body 50, where the spring element 52 can be compression spring, plate spring or torque spring and provides spring contact force when the temperature-sensing head 51 is in contact with the heat pipe 1.
Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
