The invention relates to a method for separating and screening fungi on the surface of koji-covered straw in the technical field of biological separation, which comprises the following steps: S1, taking a koji-covered straw sample, adding sterile normal saline, oscillating to fully disperse microorganisms, preparing a bacterial suspension mother solution, and carrying out gradient dilution to obtain bacterial suspensions with different concentrations; s2, separation and purification: coating a rose-bengal culture medium with the bacterial suspensions with different concentrations, carrying out inverted culture, picking single colonies, and inoculating the single colonies to a new rose-bengal flat plate for purification; and S3, molecular identification: extracting the purified strain genome DNA, carrying out PCR amplification by using fungus universal primers ITS1 and ITS4, sequencing a PCR product, carrying out BLAST comparison with an NCBI database, constructing a phylogenetic tree, and determining the strain species. According to the scheme, the fungus strain with specific functional characteristics for white spirit processing is obtained.

The application discloses a server CPU heat dissipation device, belonging to the technical field of server CPU heat dissipation, which comprises a heat-conducting base, heat dissipation fins arranged on the heat-conducting base and a Stirling machine arranged at the central position of the heat dissipation fins; the Stirling machine is attached and installed with the heat-conducting base, the heat-conducting base forms the hot end of the Stirling machine, and the heat dissipation fins form the cold end of the Stirling machine; a generator is drivingly connected to the rotating shaft of the Stirling machine, and the generator is connected with a storage battery through a transformer. The heat-conducting base absorbs the heat of the CPU, has a higher temperature, and becomes the hot end of the Stirling machine; the hot air exchanges heat with the surrounding air at the heat dissipation fins, has a reduced temperature, and forms the cold end of the Stirling machine. The stable and continuous operation of the Stirling machine is realized, the generator is driven to rotate to generate electricity, and the electric energy is stored in the storage battery. The application realizes the recycling of the heat dissipated by the CPU, reduces the influence on the environment around the server, reduces the waste of heat, improves the energy conversion utilization rate, saves the external power supply, and saves the operation cost.
