Description
[technical field]
The utility model relates to hot interface detection platform, specifically is the mounting structure about the thermocouple wire of hot interface detection platform.
[background technology]
In recent years, fast development along with the semiconductor element integrated technique, the integrated degree of semiconductor element is more and more higher, it is more and more littler that component size but becomes, more and more higher to the requirement of heat radiation, so heat radiation becomes a very important problem, for satisfying these needs, various radiating modes are extensively used, as utilize modes such as fan heat radiation, water-cooled auxiliary heat dissipation and heat pipe heat radiation, and obtain certain radiating effect.But out-of-flatness because of the surface in contact of heating radiator and semiconductor integrated component, a desirable contact interface is not arranged, fundamentally influenced semiconductor element greatly and carried out the effect that heat is transmitted to heating radiator, so the exposure level that increase one deck thermal interfacial material increases the interface between the contact interface of heating radiator and semiconductor element just seems very necessary.
And for the selection of thermal interfacial material, its coefficient of heat conductivity is the factor of an important consideration.In the practice, the coefficient of heat conductivity of thermal interfacial material need record by experiment.Relatively Chang Yong a kind of method is called temperature gradient method.During test, thermal interfacial material is extruded and is fixed between the splendid derby of two heat conductivilitys, the hot-fluid of known dimensions flows to thermal interfacial material to be measured from a derby, and then flow to another piece derby, by analyzing the temperature distribution state (being thermograde) of the each point on this direction of heat flow, can obtain the coefficient of heat conductivity of thermal interfacial material to be measured then according to the thermal conductance formula.
Therefore, the emphasis in the test is the temperature distribution state that will obtain the each point on the derby.In the practice, be on derby, to select a plurality of points, several deep holes be set, thereby thermocouple wire is inserted the temperature of measuring these selecteed points in these deep holes.Thermocouple wire is that this two metal line only welds together as the test side at the tip, and separates with insulator in other parts by two different metal wire be combined intos.Thermopair is that the principle of utilizing two kinds of different metals can produce different voltage differences under different temperatures is come work.
Yet the diameter of thermocouple wire is superfine and soft partially, and it requires in installation process not by bending, and significant care is wanted in its installation, several thermocouple wires is installed is so just comparatively bothered.
Therefore, these thermocouple wires of installation that can be fast and accurately just become a problem demanding prompt solution.
[summary of the invention]
The purpose of this utility model is to provide a kind of thermal interfacial material test platform that thermocouple wire can be installed fast and accurately.
The utility model thermal interfacial material test platform comprises first, second derby that is oppositely arranged, some thermocouple wires, and be used to install the installing mechanism of this thermocouple wire.Formation one is used to accommodate the space of stationary heat boundary material between first and second derby, is provided with the mounting hole of some thermocouple wires in this first and second derby in predetermined place.This installing mechanism comprises collets and is arranged in the some insulating sleeves that can accommodate thermocouple wire in advance in the collets, described insulating sleeve is corresponding separately with described mounting hole, after thermal interfacial material was fixed between first and second derby, described insulating sleeve correspondence of accommodating thermocouple wire in advance was installed in the described mounting hole.
But many thermocouple wires of installing mechanism one-step installation of thermocouple wire of the present utility model are saved time, and can guarantee thermocouple wire in the process of installing not by bending.
[description of drawings]
Fig. 1 is the synoptic diagram of an embodiment of the utility model thermal interfacial material test platform.
[embodiment]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
See also Fig. 1, according to a kind of embodiment of the present utility model, this thermal interfacial material test platform includes first, second derby 10,20 that is oppositely arranged, six roots of sensation thermocouple wire 40 and be used to install the installing mechanism 50 of thermocouple wire 40.Thermal interfacial material 100 is fixed in and is used between this first and second derby 10,20 measuring.
First and second derby 10 need have good heat conductivity, can select metallic copper for use, first derby 10 is as fire end, promptly carry a certain size hot-fluid to thermal interfacial material 100, this type of thermal communication is crossed after the thermal interfacial material 100, flow through second derby 20, like this, on first and second derby 10,20, form the thermograde that a temperature reduces gradually.Respectively establish three mounting holes 30 totally six mounting holes 30 in first and second derby 10,20, be used to accommodate thermocouple wire 40.These mounting holes 30 are not through whole derby thickness.
Thermocouple wire installing mechanism 50 comprises that the collets 52 that usefulness bakelite (Bakelite) material is made and the six roots of sensation are arranged in insulation casing 54 wherein.Bakelite is a kind of phenolic resin material, and it has excellent heat-insulating property.Insulation casing 54 is used for ccontaining thermocouple wire 40, and plastics or glass that its material can be selected to have heat-insulating property are made, and the hardness of the material of its selection should guarantee that it still can keep certain shape in inserting mounting hole 30.Distance between the mounting hole 30 of the distance between the sleeve pipe 54 and first and second derby 10,20 is corresponding.
Before measuring process, focus amphitene 40 promptly is arranged in the corresponding insulating sleeve 54 in advance, and outside the test side 42 of thermopair 40 is exposed to.
In measuring process, thermal interfacial material 100 can be subjected to certain pressure (installation drawing of exerting pressure does not show), make thermal interfacial material 100 remain in about 0.076mm at the thickness on the direction of heat flow, therefore when each the measurement, the distance between each mounting hole 30 is certain.
After thermal interfacial material 100 is fixedly finished; with insulating sleeve 54 and mounting hole 30 each autoregistration, disposable then six roots of sensation thermocouple wire 40 is installed in the mounting hole 30 simultaneously, because the protective effect of insulating sleeve 54; can guarantee that not only thermocouple wire 40 is not bent, and save the set-up time.
After thermocouple wire 40 installed, this temperature can be detected in the test side 42 that is exposed to the thermocouple wire 40 outside the insulating sleeve 54, thereby calculates the coefficient of heat conductivity of thermal interfacial material 100 according to the thermometer of each point.
The number of thermocouple wire 40 can be chosen according to actual conditions, and is not limited to the six roots of sensation in the above-mentioned embodiment, and mounting hole 30 also can be according to the actual conditions setting, and is not limited to the above-mentioned mode that is arranged at fifty-fifty in first and second derby 10,20.
