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.

The application provides a bacillus australimaris strain M04, a bacterial fertilizer, a fermentation agent and application thereof, and belongs to the technical field of microorganisms.The application provides a bacillus australimaris strain M04 with a preservation number of CGMCC No.30262.It is proved by experiments that the bacillus australimaris strain M04 has the ability of calcium dissolution, can improve the content of effective calcium in soil, improve the soil environment, can also produce auxin to promote plant growth; in addition, the bacillus australimaris strain M04 has good cellulase activity and the characteristics of salt and alkali tolerance, can effectively promote the rotting of organic fertilizer such as straw in a high-salt environment, has a positive effect on accelerating the conversion and utilization of straw returned to the field, and has a wide application prospect in the preparation of salt and alkali tolerant multifunctional biological organic fertilizer.
