This invention discloses a molten salt pump with a bearing cooling system, belonging to the technical field of high-temperature molten salt pumps. It includes: a pump body, a pump shaft, a frame, a bearing housing, a cooling device, and a support frame. The pump body is mounted on the frame; the frame is mounted on the top of the pump body, and the bearing housing is mounted within the frame. The pump shaft is rotatably connected to the bearing housing via bearings. The cooling device is installed inside the bearing housing, with multiple microchannel coils respectively fitted onto the outer surface of the bearing. A flywheel energy storage device is installed inside the bearing housing, driving ambient air to enter through the air inlet and generating a forced airflow that blows across the cooling end of the cooling device for heat exchange. The cooling end of the cooling device is connected to a cold air inlet pipe, which is connected to multiple microchannel coils, and all microchannel coils are connected to an outlet pipe. An outlet is provided at the bottom of the bearing housing, and the outlet pipe is connected to the outlet. This invention miniaturizes and integrates a compressor-free cooling device into the bearing housing for active phase change cooling, extending the lifespan of the molten salt pump.

The application discloses a workshop constant temperature and humidity control method and system based on ultrasonic cold atomization, and belongs to the technical field of industrial environment control. In view of the defects of high energy consumption, heat interference, control lag and too tight coupling with a production system of a steam humidification mode in the prior art, the method comprises the following steps: obtaining real-time humidity of a workshop, and generating a standard industrial simulation control signal by an air conditioner main control unit; the signal is converted into a driving signal through an independently arranged signal conversion control module, and normal-temperature atomized water vapor output by an ultrasonic cold atomization humidification device is controlled, so that the original steam humidification device is completely replaced. The system also has a manual control mode and a state display function, and can realize decoupling of humidification and a boiler, so that the boiler is completely stopped when a production line is shut down. The application replaces fossil fuels with electric energy, saves energy and reduces cost, eliminates heat interference and improves temperature control accuracy, and can be seamlessly integrated without modifying the original PLC program, thereby supporting lean energy management.

The invention relates to the technical field of heat dissipation of new energy automobiles, in particular to a three-dimensional-based double-layer flow three-temperature-zone fluid control liquid storage tank assembly which comprises an upper pot body, a lower pot body and an upper pot body. The lower pot body is located under the upper pot body and detachably connected with the upper pot body, a T-shaped partition plate is fixedly arranged in the lower pot body and divides the lower pot body into three independent liquid storage cavities, a filling pipe is arranged at the plate body connecting position of the T-shaped partition plate in the vertical direction, and the lower end of the filling pipe is fixedly connected to the inner bottom face of the lower pot body. First communicating grooves communicating with the three liquid storage cavities are formed in the lower end of the side wall of the filling pipe, and heat insulation grooves are formed in one sides of three plate bodies of the T-shaped partition plate located on the outer side of the filling pipe; the circulation driving mechanism is fixedly arranged on the bottom face of the lower kettle body and used for enabling cooling liquid in the three liquid storage cavities to flow out independently. The control liquid storage tank assembly is high in integration level, can be suitable for centralized heat dissipation of an automobile multi-heat system, is good in heat insulation effect among subsystems, and can effectively avoid heat interference.
