The research and development explanation:

The present invention takes following measure in device structure and parts selection:

1. select high material radiator and the heat conduction member of the coefficient of heat conduction.

The coefficient of heat conduction of common used material is respectively: copper 401, aluminium 250, iron 84~90, air 0.03.Casing cover plate 3 aluminium alloy-steel castings among the present invention, heat conduction backing plate 4 selects sheet copper or thin aluminum sheet.

2. increase the volume and the surface area of radiator.

The radiator volume increases, and can receive more heat energy.The surface area of radiator increases, and the heat energy that gives out through the cooling water and air increases.The present invention casts in cover plate tank 15 on the casing cover plate 3, and casing cover plate 3 was compared in the past thickening again, casing cover plate 3 volumes is all compared with installation tank cover plate 2 later surface areas increased more than 1 times in the past.Compare with cover plate with the casing of existing percussion grinder, the volume and the surface area of stator component heat abstractor of the present invention and heat radiator on casing all increase more than 2 times.

3. increase the heat exchange area between radiator and the heat conduction member.

Radiator receives the value of heat energy and contact area proportional from heat conduction member.Through 4 settings such as grade of heat conduction backing plate, the present invention increases the contact area of cover plate bottom surface and stator discs 9 more than 3 times.

4. replace air transmitted with the metal conduction pattern.

Calculate that by data record data the coefficient of heat conduction of copper is 1.3 ten thousand times of air, the coefficient of heat conduction of aluminium is more than 8300 times of air.Being clipped in the heat conduction backing plate 4 between stator pin 6 end of thread end faces on casing cover plate 3 bottom surfaces and the stator discs 9 in the stator component heat abstractor is exactly the air transmitted that replaces prior art with the metal conduction pattern.Heat conduction backing plate 4 directly conducts the heat energy on the heat energy carrier stator pin 6 with the metal conduction pattern gives radiator (casing cover plate 3), and its heat conduction efficiency improves hundreds of times than air transmitted at least, so this measure effect is significantly unquestionable.

Heat conduction backing plate 4 is on sheet copper or thin aluminum sheet, to stamp out thickly dotted tiny pit to process.Product design requires processing machine housing-plate 3 and installs the stator discs 9 of pin and select for use heat conduction backing plate 4 that following requirement is arranged: in the time of can guaranteeing that stator discs 9 is fixed on the cover plate, the gap is than the big 0.2~1mm of thickness of selected heat conduction backing plate 4 between stator pin 6 ends of thread (being top shown in Figure 1) end face and the cover plate bottom surface.Pressure when assembling like this just can flatten the bossing of heat conduction backing plate 4 basically; Make heat conduction backing plate 4 upper and lower surfaces have enough areas to fit tightly with stator pin 6 end of thread end faces with casing cover plate 3 bottom surfaces respectively and be in the same place, the heat energy that accumulates on the stator pin 6 just can be transmitted to cover plate with the metal conduction pattern.

In a word, above-mentioned measure of the present invention can be taken away heat energy through the cooling water and air, and the temperature of cover plate and casing 5 inner surfaces can be descended about 20 ° of C, and the temperature rise of being clashed into material is obviously descended.Adopt the present invention can make that the quality of production line output finished product obviously improves, the finished product edible quality is obviously improved.In addition; Above-mentioned measure is also dwindled more than 80% with the cavity that amplifies the sound causing sympathetic response between stator discs 9 and the cover plate; Add the cooling water sound absorption, so the noise ratio prior art obviously reduces when the present invention is turned round, its economic benefit and social benefit are quite remarkable.
