The invention discloses a holding pole power supply. The holding pole power supply comprises a circular ring-shaped box to be installed on a supporting rod; the center of the circular ring-shaped boxis provided with a cylindrical cavity, and the cylindrical cavity is used for encircling the supporting rod; a plurality of battery cells are uniformly arranged inside the circular ring-shaped box; and when the holding pole power supply is installed on the supporting rod, the center of gravity of the holding pole power supply is positioned on the cross section of the supporting rod. Through the implementation of the embodiment, the stability of the holding pole power supply can be improved, and simultaneously, the problem of local overheating caused by the fact that the heat dissipation amongthe battery cells in the holding pole power supply is inconsistent is avoided, so that the service life of the holding pole power supply is prolonged.

The invention discloses a three-dimensional radio frequency module manufacturing method based on a multi-layer heat dissipation structure. The method specifically comprises the following steps: 101) an adapter plate manufacturing step, 102) a bottom plate manufacturing step, 103) a bonding step, and 104) a chip placement step. A heat conduction metal or a heat conduction pipeline is arranged at the bottom of a chip, the heat can be quickly conducted into a heat dissipation base, then, a plurality of layers of micro-channel liquid-phase heat dissipation channels are arranged in the heat dissipation base, and a cooling liquid in the heat dissipation channels moves in different flowing directions, so that the temperatures of the liquid in the micro-flow channels in different layers and on onesides of different chips are balanced, and the heat dissipation capacity of the micro-flow channels at the bottom of the chip tends to be consistent.

The invention relates to an LED light-emitting device and a preparation method thereof. The device comprises a substrate, an LED chip and an organic layer arranged on the substrate. It is characterized in that a refractive index buffer layer with a refractive index between the LED chip and silica gel is provided between the LED chip and the organic layer, and the refractive index buffer layer guides the light emitted by the LED chip into the The organic layer allows more light to pass through the organic layer. The organic layer is covered with a non-uniform luminescent powder layer, and the non-uniform luminescent powder layer includes at least two different types of luminescent powder layers arranged in layers or luminescent powder layers of the same type with different particle sizes. Phosphor powders of the same type or particle size in the layer are uniformly arranged, and phosphor powders of different types or particle sizes are relatively non-uniformly arranged.

The invention discloses a method for spreading and drying fermented grains for improving uniformity of cooling the fermented grains and the uniformity of mixing the fermented grains and yeast powder, and belongs to the technical field of brewing. The method comprises the following steps of: a. evenly spreading the distillated and pasted fermented grains to form a fermented grain layer with a certain thickness; b. evenly scattering the yeast powder on the surface of the fermented grain layer, and dividing the position on which the fermented grain layer is positioned into n turning regions which are respectively a first region (1), a second region, a third region to a n-1 region and a n region (2); turning and mixing the fermented grains at the first region (1) and the second region, and then evenly spreading the fermented grains on the first region (1) and the second region; turning and mixing the fermented grains at the second region and the third region, and then evenly spreading thefermented grains on the second region and the third region; and orderly turning the fermented grains according to the method till turning and mixing the fermented grains at the n-1 region and the n region, and then evenly spreading the fermented grains on the n-1 region and the n region. The method is simple to operate; the heat dissipation of the fermented grains is consistent; and the fermentedgrains are evenly mixed with the yeast powder.
