Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1-Fig. 7, a kind of IEGT surface heat-conducting silicone grease dauber, comprise base 1, upper ledge 2, web plate 3, support 4, scraper plate 5, base 1 and upper ledge 2 are movably hinged, and IEGT is fixed on support 4, support 4 is arranged on base 1, web plate 3 is fixed in upper ledge 2, and position corresponding with IEGT on web plate 3 is evenly provided with some mesh, and scraper plate 5 entirety adopts PVC plastic to process, fillet is led in scraper plate 5 lower surface, during to reduce blade coating and the frictional force on web plate 3 surface.
Base 1 comprises box body 6, pillar 7, gripper shoe 8, adjusting knob 9, and pillar 7 and gripper shoe 8 are bolted on box body 6; Adjusting knob 9 top is screw rod, and screw in gripper shoe 8, screw tip is provided with support 4, regulates support 4 height by screw rod.The front end of box body 6 is provided with handle 10, and base 1 is general, can be applicable to smearing of Multiple Type IGET heat-conducting silicone grease by changing support 4.
Upper ledge 2 comprises built-in beam 11, locating piece 12, fixed knob 13, and built-in beam 11 is provided with locating piece 12, and web plate 3 is fixed by fixed knob 13 and built-in beam 11.Support 4 is integral type structure.Upper ledge 2 can be general, when the IEGT blade coating heat-conducting silicone grease to different model, only need change the web plate 3 of corresponding specification.
Web plate 3 adopts 304 stainless steels to make, thickness 0.12mm, surface has circular mesh, the size of circular mesh and distribution are according to IEGT installed surface size and required heat-conducting silicone grease amount design of smearing, utilize web plate 3, applying amount that scraper plate 5 blade coating effectively can control heat-conducting silicone grease, and the uniformity of silicone grease in IEGT surface distributed can be ensured.
Circular mesh design is as follows:
1. IEGT installed surface area S:
S＝πr
2
In formula: r is the radius of IEGT installed surface;
2. the consumption V of heat-conducting silicone grease is calculated:
V＝S×H
In formula: H is the heat-conducting silicone grease thickness of IEGT standard, the heat-conducting silicone grease thickness of standard is 10-15 μm;
