At the top end of the testing base, there is an interface frame located directly above the heating heat source. A radiator is provided at the top end of the interface frame. The interior of the interface frame is filled with a to-be-tested interface material that abuts against the heating heat source and the radiator. Thermocouple distribution points that abut against the to-be-tested interface material are provided in the middle of the heating heat source and the middle of the radiator.
[0006] As a preferred technical solution of the utility model, a plurality of heat source support columns that are vertically upward and limit and support the heating heat source are provided inside the placement groove.

[0011] The beneficial effects of the present utility model are as follows:
[0012] 1. When testing the thermal conductivity of the interface material to be tested with this flexible interface material testing device, the interface material to be tested is filled into the interior of the interface frame, so that the interface material to be tested inside the interface frame is in contact with the heat dissipation heat source.

A placement groove 2 is formed at the top end of the test base 1. A heating heat source 3 is placed inside the placement groove 2. An interface frame 4 is provided at the top end of the test base 1 and is located directly above the heating heat source 3. A radiator 5 is provided at the top end of the interface frame 4. The inside of the interface frame 4 is filled with a to-be-tested interface material 6 that abuts against the heating heat source 3 and the radiator 5. Thermocouple layout points 7 that abut against the to-be-tested interface material 6 are provided in the middle of the heating heat source 3 and the middle of the radiator 5.
[0022] Among them, a plurality of heat source support columns 8 that are vertically upward and limit and support the heating heat source 3 are provided inside the placement groove 2. The total height of the heating heat source 3 and the heat source support columns 8 is greater than the depth of the placement groove 2, so that the to-be-tested interface material inside the interface frame can contact the heating heat source 3.
[0023] Among them, the radiator 5 adopts a fin radiator, and the heat dissipation effect is better.
[0024] During operation, when testing the thermal conductivity of the to-be-tested interface material 6 with this test device for a flexible interface material, the to-be-tested interface material 6 is filled into the inside of the interface frame 4, so that the to-be-tested interface material 6 inside the interface frame 4 abuts against the heat dissipation heat source. The setting of the interface frame 4 facilitates the positioning and placement of the to-be-tested interface material 6. The heating heat source 3 can heat the to-be-tested interface material 6. The setting of the placement groove 2 facilitates the positioning of the heating heat source 3. The setting of the thermocouple layout points 7 facilitates the testing of the thermal conductivity of the to-be-tested interface material 6, and the setting of the radiator 5 can dissipate heat from the interface frame 4.
[0025] Example 2, as Figure 1 and Figure 2 shown, the difference technical feature from Example 1 is that a positioning mechanism for positioning the interface frame 4 and the radiator 5 is provided at the top end of the test base 1. The positioning mechanism includes positioning columns 9 provided at the top end of the test base 1 and located at the corners of the placement groove 2. Positioning holes 10 through which the positioning columns 9 pass are formed on the interface frame 4. A positioning groove 11 that matches the top end of the positioning column 9 is provided at the bottom end of the radiator 5.
[0026] During operation, when filling the interior of the interface housing 4 with the interface material 6 to be measured, the radiator 5 is removed, so that the positioning groove 11 on the radiator 5 is separated from the positioning rod, and then the interface material 6 to be measured can be filled into the interior of the interface housing 4. Then, by matching the positioning groove 11 on the radiator 5 with the positioning rod, a good positioning effect can be achieved, realizing the rapid positioning of the radiator 5. Among them, a positioning hole 10 through which the positioning post 9 passes is provided on the interface housing 4, which can quickly position and install the interface housing 4.
