Technical field:
The present invention is a kind of heat radiating water jacket that is used for magnetron and preparation method thereof, belongs to the innovative technology of heat radiating water jacket of being used for magnetron and preparation method thereof.
Background technology:
In magnetron, adopting heat radiating water jacket is a kind of new method for designing as its radiator, adopted by some users, but along with also there are some problems simultaneously in the use of heat radiating water jacket, one of them problem that is difficult to solve is exactly that the heat radiating water jacket inner surface exists incrustation scale after use after a while, incrustation scale makes the heat radiating water jacket inner surface form one deck heat-barrier material, causes radiating condition to worsen.In addition, incrustation scale too much easily makes the jacket passage reduce by area, and flowing water is not smooth, is difficult for heat radiation, and the temperature of heat radiating water jacket is raise, and radiating effect reduces, and water pipe is stopped up.The reason that incrustation scale forms is because the cooling water that uses in the magnetron heat radiating water jacket does not generally all have to handle through softening, contains various salts in the water, and when magnetron was worked, water temperature raise.Because cooling water heat absorption, evaporation, salt density in the water is increased gradually, when reaching capacity state, salt in the water is separated out or because the chemical property of salt is lively with the increase of temperature, the hydrolysis of salt is accelerated, and separate out after generating new salt, being deposited on the inner surface of water jacket, this sedimentary deposit is incrustation scale.
Summary of the invention:
The objective of the invention is to overcome above-mentioned shortcoming and a kind of heat radiating water jacket of avoiding occurring incrustation scale after use is provided.The present invention's flowing water in use is freely suitable, good heat dissipation effect.
Another object of the present invention is to provide a kind of making simple, the preparation method of the heat radiating water jacket that is used for magnetron that cost is low.
The structural representation of heat radiating water jacket of the present invention as shown in drawings, heat radiating water jacket (1) includes heat radiating water jacket kerve (11) and heat radiating water jacket cover plate (12), heat radiating water jacket kerve (11) is connected with heat radiating water jacket cover plate (12), and wherein the inner surface of the inner surface of heat radiating water jacket kerve (11) and heat radiating water jacket cover plate (12) is stained with coating (2).
The thickness of above-mentioned coating (2) is 0.02～0.03mm.
The raw material of above-mentioned coating (2) are polyflon.
The present invention prepares the above-mentioned method that is used for the heat radiating water jacket of magnetron, and it includes the following step:
1) processes heat radiating water jacket kerve (11) and heat radiating water jacket cover plate (12);
2) greasy dirt of cleaning heat radiating water jacket kerve (11) and heat radiating water jacket cover plate (12);
3) utilize the thermally sprayed coating method that the raw material of coating (2) are coated on the heat radiating water jacket inner surface;
4) spray coating and afterwards heat radiating water jacket kerve (11) and heat radiating water jacket cover plate (12) are put into baking oven, form the film coating (2) that sticks to heat radiating water jacket kerve (11) inner surface and heat radiating water jacket cover plate (12) inner surface by dry, sintering;
5) heat radiating water jacket kerve (11) and heat radiating water jacket cover plate (12) are welded as a whole promptly are shaped to heat radiating water jacket (1).
Above-mentioned steps 3) thermally sprayed coating method is:
A) polyflon coating is extremely melted or the semi-molten state through arc heating;
B) make the above-mentioned polyflon coating atomizing that is heated to fusing or semi-molten state with air-flow, and spray in the inner surface of heat radiating water jacket kerve inner surface and heat radiating water jacket cover plate, molten state atomization metal particle is got to heat radiating water jacket kerve inner surface and heat radiating water jacket cover inner surface.
Above-mentioned steps 4) sintering temperature is 360 ℃～400 ℃;
Above-mentioned steps 1) with cutting out heat radiating water jacket kerve (11).
Above-mentioned steps 1) die casting goes out heat radiating water jacket cover plate (12).
The present invention makes its inner surface at heat radiating water jacket produce one deck smooth surface owing to adopted the structure that is coated with the last layer coating at the heat radiating water jacket inner surface, strengthens surface flatness.Make in the water salt incrustation can't stick to the water jacket inner surface and taken away by current at any time.Therefore, it can avoid occurring incrustation scale after use, and heat radiating water jacket of the present invention flowing water in use is freely suitable, and good heat dissipation effect is a kind of reasonable in design, the convenient and practical heat radiating water jacket that is used for magnetron.In addition, the preparation method of heat radiating water jacket of the present invention makes simply, the efficient height, and cost is low.
