Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail the utility model.
A kind of device of power module radiating surface coated with thermally conductive silicone grease is present embodiments provided, structure is as shown in Figure 1, packet
Containing pedestal 3, top board and mating scraper 2.
For pedestal 3 for disposing power module, the material selection antistatic material compound stone of pedestal 3 avoids breakdown power supply mould
Block.It is opened among pedestal 3 there are one ontology slot, the shape and size of shape and size and power module are adapted, power module
It is inverted in ontology slot.The bottom of the present embodiment power module is smooth, and into a ladder, cross section is convex for upper surface.Electricity
There are the pins that two rows of height differ in source module upper surface both ends ladder lower and height of pin is higher than the surface among ladder,
This causes when coating DOW CORNING heat-conducting silicone grease on power module bottom, and power module, which can wave, not to stop.Therefore, as shown in Fig. 2,
The ontology slot both ends of the pedestal 3 of the present embodiment separately design there are one run through pedestal 3 strip straight slot so that power module two
The pin at end is located in strip straight slot.The thickness of pedestal 3 is not less than power module and its height of pin length, to ensure bottom
Seat 3 keeps stablizing in the horizontal plane.The thickness of 3 ontology slot of pedestal is consistent with the height of power module.Due to DOW CORNING heat conduction
Silicone grease has mobility, in order to ensure to coat the accuracy of position, disposes the ontology slot of power module must be according to power supply mould
The appearance and size of block determines.It is convenient in order to pick and place power module on the base 3, therefore the ontology slot two sides of 3 upper surface of pedestal
Place's symmetric design has one group of arc groove for picking and placeing power module, and neither influence placement does not influence to position again.
The shape and structure of top board including top board silk-screen as shown in figure 3, coat panel border 1 and the painting of top board silk-screen
Cladding boards 5.The material of top board silk-screen coating panel border 1 equally selects antistatic material compound stone, avoids breakdown power supply mould
Block.The material of top board silk-screen coating panel 5 for steel plate, processing and using when be unlikely to deform, can also reach technological requirement.Due to
It is 0.2mm that Product Process, which requires to need the coating layer height of power module, so silk-screen coating panel material selection 0.2mm steel
Plate.Top board silk-screen 5 medium design of coating panel is there are two slotting, for being led in the power module surface of exposing coating DOW CORNING
Hot silicone grease.In order to ensure the coat consistency of thickness of power module, therefore top board silk-screen coating panel is designed as two
Fluting, midfeather 1mm are unlikely to intermediate firmly too big and cause inter-coat layer height relatively low.
Top board silk-screen coating panel 5 also is able to the degree of freedom of limitation power module.Since top board is in the process of extruding
In, top board silk-screen coating panel 5 cannot deform, so after top board is connect with pedestal 3, the size of ontology slot is especially important,
Pedestal 3 is too high to cause power module closely coupled with top board silk-screen coating panel 5, and coating effect is bad；Pedestal 3 is too low
Top board silk-screen coating panel 5 is easily deformed, and coating procedure becomes difficult.
Further, since there are two rows of threaded holes on power module bottom, when Product Process requirement coats DOW CORNING heat-conducting silicone grease
DOW CORNING heat-conducting silicone grease be cannot flow into threaded hole in order to avoid causing fifth wheel.Therefore, top board silk-screen coating 5 surrounding of panel is pressed
Add semicircle according to screw thread hole number and size design rectangle, semicircle is concentric with threaded hole and semicircular edge is only more than screw thread bore edges
1mm。
Top board silk-screen coating panel 5 is used in conjunction with each other the present apparatus with the needs of pedestal 3 in use, because of road health
Peaceful heat-conducting silicone grease self character has stronger mobility, in order to ensure not flowing into DOW CORNING heat-conducting silicone grease, upper pressure in threaded hole
Plate silk-screen coating panel 5 needs to be aligned when with pedestal 3 coordinating, and otherwise the precision of 1mm is easily flowed into threaded hole, therefore upper pressure
When plate silk-screen coating panel 5 is connect with pedestal 3, using diagonal orientation pin 4, top board silk-screen can not only be quickly and easily installed
Panel 5 and pedestal 3 are coated, but also the degree of freedom of power module can be limited.
Matching used scraper 2, including handle and blade two parts.Of length no more than top board silk-screen coated side of handle
5 size of plate, in 45 degree, handle cannot coat panel border 1 with top board silk-screen and contact scraper 5, cause coating difficulty during use,
Blade width should be less than handle width, but not less than 10mm, avoid in firmly coating procedure, blade bending is made when pressure is inadequate
Uneven into coating surface, thickness is inconsistent.
When the technical solution using the present embodiment makes silk-screen coat DOW CORNING heat-conducting silicone grease, first according to power module
Shape and size make a pedestal 3, can be placed on what power module was stablized wherein；Then, face makes one on the base 3
The top board silk-screen coating panel 5 of 0.2mm thickness, is closely pressed on power module；Top board silk-screen coating panel 5 can not only be consolidated
Determine power module to be not moved, and the threaded mounting hole of power module can also be blocked, effectively prevent DOW CORNING thermal conductive silicon
Fat is flowed into threaded mounting hole.Then, DOW CORNING heat-conducting silicone grease is placed on 5 surface of top board silk-screen coating panel, with self-control
Mating scraper 2, to power module carry out silk-screen coating DOW CORNING heat-conducting silicone grease, the DOW CORNING heat-conducting silicone grease after coating is smooth,
Neatly, consistency of thickness is uniform.Then the power module after coating DOW CORNING heat-conducting silicone grease is placed on radiator corresponding position, used
Screw fastens power module, stands for a moment, only has a small amount of DOW CORNING heat-conducting silicone grease to be extruded around power module, it was demonstrated that power supply
It is all had been filled between bottom and radiator completely, the operating time of a product is 7 minutes or so.
The coating unit of the present embodiment can also coat jelly with certain fluidity etc., energy in various body surfaces
It is smooth clean and tidy enough to reach coating surface, thickness is uniform, saves the effect of operating time.Obviously, those skilled in the art can be with
Spirit and scope of the various modification and variations without departing from the utility model are carried out to the utility model.If these modifications and change
Type belongs to the scope of the claims of the present invention and its equivalent technology, then the utility model is also intended to comprising these changes
Including modification.
