Description

Hot pipe temperature measuring method

Technical field

The present invention relates to a kind of hot pipe temperature measuring method, particularly a kind of contact and the hot pipe temperature measuring method that reduces thermal contact resistance when increase detecting the heat pipe surface temperature.

Background technology

General heat pipe for guaranteeing large quantities of heat pipe qualities of making, needs all at first that opposite heat tube carries out the testing of amount of thermal conduction, in the hope of bringing into play thermal conduction effect after manufacturing is finished.Yet, detecting instrument in the past or equipment, because unit price costliness, and exist operating process too numerous and diverse, detect problems such as required spended time is long, for example thermocouple wire (thermal couplewire) is sticked on heat pipe surface etc., detect so can't do bulk sample, thereby only can adopt the mode of sampling observation the heat pipe of volume production with adhesive tape, to calculate after each heat pipe sampling Detection of producing in batches its may acceptance rate conformance with standard whether, to reach the purpose of keyholed back plate quality.

Shown in Figure 1 is a kind of easier hot pipe temperature measuring mode of prior art, wherein, earlier with the end in contact of thermocouple wire 10a on the heat pipe 1a surface for the treatment of thermometric, and this end of thermocouple wire 10a is attached on the heat pipe 1a surface with adhesive tape 11a, make in the thermometric process and can stablize contact, to carry out the thermometric operation.Yet, when desire is torn adhesive tape 11a after detection is finished, easily at heat pipe 1a remained on surface cull, so must increase follow-up clean-out operation, or cause heat pipe 1a distortion, damage etc. because of the power of tearing is excessive, causing influencing product quality, and caused the detection operation comparatively time-consuming.

Therefore, disclose novel patent cases such as " hot pipe temperature measuring clamp structures " for solving the above problems in the prior art.Be the contact and reduction thermal contact resistance (thermal resistance) that can further increase thermometric structure and heat pipe surface, the inventor is through studying intensively and cooperate the utilization of scientific principle, proposes a kind of reasonable in design and effectively improve the present invention of above-mentioned defective finally.

Summary of the invention

Fundamental purpose of the present invention, being to provide a kind of hot pipe temperature measuring method, when thermocouple wire contacts with the heat pipe surface, utilization has the fluid media (medium) of cohesion, Ru Shui, oil or viscosity are lower and have mobile body of paste etc. and insert between the two, the stability of the thermal contact resistance when detecting the heat pipe surface temperature to increase with reduce thermal contact resistance.

To achieve the above object, the invention provides a kind of hot pipe temperature measuring method, its step comprises:

(a) form temperature-sensitive head at the end end of thermocouple wire;

(b) this temperature-sensitive head is pressed heat pipe surface, and between this temperature-sensitive head and this heat pipe surface, add the fluid media (medium) of tool cohesion, to carry out the thermometric operation in temperature to be detected.

Owing to fluid media (medium) can have mobile body of paste for water, oil or viscosity are lower, and has a characteristic of cohesion, so can fill up the space between temperature-sensitive head and heat pipe surface, make the temperature-sensitive head that is a contact originally increase the stability of the thermal resistance that contacts between the two because of inserting of fluid media (medium), and can effectively increase the contact effect to reduce thermal contact resistance with heat pipe.

Embodiment

In order further to understand feature of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet appended accompanying drawing only provide with reference to and explanation, be not to be used for the present invention is limited.

The A part enlarged drawing of synoptic diagram when Fig. 2 and Fig. 3 are respectively the invention process and Fig. 2.The invention provides a kind of hot pipe temperature measuring method, it mainly at first prepares thermocouple wire 10, end end at this thermocouple wire 10 forms temperature-sensitive head 100, the other end is then in order to connect temperature sensing device (figure slightly), can show or write down measured temperature, the temperature-sensitive head 100 by this thermocouple wire 10 is passed to temperature sensing device with the temperature signal that records.

And the forming mode of this temperature-sensitive head 100, can impose welding at the end end that thermocouple wire 10 is the bare wire shape, so that its fusing back forms the temperature-sensitive head 100 (as shown in Figure 2) of spheroidal naturally, stable contact heat pipe surface when this spherical temperature-sensitive head 100 can further be guaranteed thermometric, perhaps, directly be the bare wire end and form temperature-sensitive head 100 ' (as shown in Figure 4) with the heat-conducting coating at this thermocouple wire 10.

After finishing above-mentioned preparation process, as shown in Figures 2 and 3, can be with this temperature-sensitive head 100,100 ' press on heat pipe 1 surface of temperature to be detected, and at this temperature-sensitive head 100,100 ' and heat pipe 1 surface between add an amount of fluid media (medium) 11, this fluid media (medium) 11 can be water, oil or viscosity are lower and have a mobile body of paste, the characteristic that has cohesion by these materials, can fill up at temperature-sensitive head 100,100 ' and heat pipe 1 surface between the space, can make the temperature-sensitive head 100 that was a contact originally, 100 ' increase the stability of the thermal resistance that contacts between the two because of inserting of fluid media (medium) 11 with heat pipe 1, and can effectively increase the contact effect to reduce thermal contact resistance, so when carrying out the thermometric operation, can make the numerical value that is detected in the thermometric operation more correct.After detection is finished,, do not need the time of overspending to carry out clean-out operation simultaneously yet, also can reach the purpose of fast detecting so can guarantee the quality of heat pipe 1 because fluid media (medium) 11 is easy to wash and can not cause the damage of heat pipe 1 in cleaning course.

According to above-mentioned contexture, can obtain hot pipe temperature measuring method of the present invention.

Therefore, hot pipe temperature measuring method of the present invention not only helps can make temperature-sensitive head 100,100 ' more stable with contacting of heat pipe 1 in the thermometric operation, thermal resistance value is also comparatively stable, to record accurately outside the numerical value, simultaneously removing the problems such as difficulty that also can not cause the damage of heat pipe 1 in the operation or cause clean-out operation, so the testing of screening one by one when examining in a large number or entirely.

The above only is a most preferred embodiment of the present invention, and the present invention is not limited to these embodiment, and the variation of the equivalence techniques that all utilizations instructions of the present invention and accompanying drawing content are done, means etc. all should be within the scope of the present invention.
