DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for producing fresh pores, and more particularly to a method for screening powders. [Prior Art] At this stage, for the electronic series of the high-temperature recording, people use the combination of the secret tube, the loose-angle fin and the cooling fan to dissipate heat. The heat (four) part of the New Zealand: 1 乍 liquid in the heating electronic components (evaporation end) depends on evaporation, moving to the heat sink fins, at the political hot Korean (condensing end) heat generated by the heating electronic components to use heat The fan takes away the heat generated and completes the divergence of the electronic components. = After the working liquid is in the condensation heat, the condensation axis, the occupational heat == reflux to the evaporation end, into the next _ jade cycle. The heat pipe has a high ratio; the rate and the heat transfer rate play an important role in the heat dissipation of electronic components. 'The thinness of the heat pipe _ is an important factor affecting the performance of the heat pipe. The conventional heat pipe capillary structure is the second type of bribe mixture that is placed in a high-temperature shot sintering period for a period of time. However, when the method of manufacturing the Mazaki structure, the powder mixture contains powders of different particle sizes, and the content of the powder in each particle size range (Surface Energy), ^ does not & 'and then the powder mixture is sintered. The required temperature range is not clear, and = one, the range of time stays _, so that the sintering temperature and sintering time are not easy to control, _,, ό / γ degree is too low or the sintering time is too short, between the powder Can not be effectively combined. If the temperature is too high and the carbonation time is too long, the powder mixture will produce money and densification, and: 40% of the capillary structure has only a few large pores that are not connected to each other, and then the capillary structure money satisfies the high money rate. And the demand for high capillary strength. Therefore, the industry hopes to find the capillary structure controlled by the temperature sintering time. The object of the present invention is to provide a porous junction l262li method which is easy to control in sintering temperature and sintering time: the method first screens out the powder of the size of the diameter, and the powder is aliquoted in plurals, and then according to actual needs. L« multiple _ multiple L* structure. Sintering or sintering according to the ratio of the ratio of the sintering to the processing of * to meet the demand of the production of the porous structure, due to the particle size of each aliquot of the powder and its time: 厶 2: the surface required to reduce the sintering Can be more clear, so that the sintering of the hall and the degree and the day is easier to control. [Embodiment] The present invention will be further described below with reference to the accompanying drawings. Use this capillary structure. Referring to the first figure, the method for manufacturing the porous structure comprises the following steps: the raw material comprises a plurality of powders having different particle sizes, and the particle size range of the powders is based on mechanical precision. Do not. The raw material has a particle size ranging from 2 Å to 22 Å mesh. The mesh of the "mesh" hole is mostly used in the standard sieve mesh to indicate the passage through the standard sieve 77;;: diameter. The larger the mesh size, the smaller the particle size of the powder. The method of screening the raw materials by the number method, so that the raw materials are successively passed through the re-grading divisions with small differences in mesh size, and the different granules are separated, and the proportion of the powders of each particle size is determined, and the normal components of the components of the raw materials are obtained. Two " π, the second pass through the mesh from small to large, shake ί 2: i too, the powder far from the division is the powder of the particle size represented by the standard sieve. ', = area: Please continue to refer to the second picture, according to the size and power of the heat pipe required to process the temple. In this example, it is divided into a, b, c, d, e, Guangfu ^Mesh, 140Mesh, 100Mesh, and wounded can be a compartmentalized point, a, ^ = solid, the particle size range is ~2 fiber Esh, (10) ~ 2 (8) test

In the case of powder, it is possible to control the formation of different pores at a lower temperature, so that the capillary structure has a certain capillary gradient, so that the capillary structure', the same permeability and the capillary force are beneficial to the improvement of the performance of the heat pipe. In the case of a single-aliquot of powder, each powder will also be necked during the sintering process, and the 'dead' of the capillary structure or the capillary force of the capillary structure and the powder containing the particle size, Compared with the lower heat pipe, it is suitable for the lower power heat pipe. For example, the fifth and sixth graphs d are not separately selected before and after the sintering of the C zone powder, and the C zone powder is burned separately, and the Mman' is formed between the powders. a pore 6 which is slightly larger than the pores 6 of the fourth figure, so that the capillary structure formed after sintering The fine force is lower than the capillary force of the capillary structure formed by selecting the powders * and 2 in the B and D regions. > The particle size of the aliquot powder is larger, and the temperature required for sintering is higher, but due to the i aliquot The particle size and quantity of the powder are relatively certain, so that the surface energy required for sintering is relatively clear, so the temperature and time required for sintering are still relatively easy to control. 1262110 Indeed, so that it burns the gentleman and the 吏The surface energy of the powder that changes when ff is different.
