Problems solved by technology
However, the contact between the tips of the two metal wires of the thermocouple and the surface of the heat pipe must be very direct and reliable, otherwise there will be an unknown contact resistance between the thermocouple and the surface of the heat pipe, resulting in a temperature difference
[0006] Existing known method all is to stick the thermocouple directly on the surface of the heat pipe with an adhesive tape, which will easily cause the contact between the tips of the two metal wires of the thermocouple and the surface of the heat pipe to be indirect and reliable, and be easily affected by the temperature of the surrounding environment. Causes an error between the measurement result and the actual temperature on the surface of the heat pipe

A fixing component of thermocouple is prepared as forming a holding body by the first and the second holding plates as well as hinging structure for hinge-jointing two said plates, containing the first and the second lock-joint unit separately at ends far from hinge-joint structure on the first and the second holding plates and enabling to lock-joint two said lock-joint units with each other; forming a containing unit with a containing groove at internal wall of the first or the second holding plate so as to contain thermocouple. The temperature measuring unit utilizing said component is also disclosed.
Description
【Technical field】 [0001] The invention relates to the field of heat pipe measurement, in particular to a thermocouple fixing jig and a temperature measurement device. 【Background technique】 [0002] In recent years, the rapid development of electronic technology, the high frequency and high speed of electronic devices and the density and miniaturization of integrated circuits have caused a sharp increase in the heat generation of electronic devices per unit volume. Heat pipe technology is suitable for solving current electronic problems due to its high efficiency, compactness, flexibility and reliability. The heat dissipation problem derived from the performance improvement of the device. [0003] The heat pipe is a hollow sealed tube, usually including a shell, a capillary wick (capillary structure) close to the inner wall of the shell, and a working fluid sealed in the shell. One end is the evaporation end (heating end), and the other end is It is the condensing end (cool...
