The plant cultivation device comprises a vertical cylinder-shaped plant cultivation frame, the plant cultivation frame is provided with multiple layers of cultivation grooves and a cylinder-shaped light source, and the light source is vertically arranged at the center of the plant cultivation frame. The plant cultivation device has the advantages that high light source space efficiency is achieved, natural lighting can be used, and light source heat is easy to manage.

The invention discloses an air guide ring and an air conditioner outdoor unit, which relate to the technical field of refrigeration devices. The air guide ring and the air conditioner outdoor unit are invented to solve the problem of generation of turbulence noise since the edge of an air outlet of the air guide ring in the prior art generates whirl airflow. The air guide ring comprises an air guide ring main body; the air guide ring main body encircles to form an air guide duct, the air guide ring main body comprises an outer layer side wall and an inner layer side wall, an annular air guide groove is formed between the outer layer side wall and the inner layer side wall, one end of the annular air guide groove close to the inlet of the air guide duct is closed, and one end of the annular air guide groove away from the inlet of the air guide duct is open. The air guide ring can be used for guiding the airflows generated by an axial flow fan.

The invention discloses a quick positioning installation assembly of a communication terminal device, and relates to the field of communication terminal installation assemblies. The quick positioning and installation component of the communication terminal device includes a wall plate and a communication terminal main body, the front of the wall plate is fixedly connected with an installation positioning plate by bolts, and the front center of the installation and positioning plate is fixedly connected with a snap seat back plate, and the snap seat back A bottom plate is fixedly connected to the front and lower end of the board, vertical blocking bars are fixedly connected to both sides of the top of the bottom plate, a terminal backboard is fixedly connected to the back of the main body of the communication terminal, and a docking plate is fixedly connected to the back of the terminal backboard by bolts. The communication terminal main body of the rapid positioning and installation component of the communication terminal device can be disassembled and assembled repeatedly, without affecting the fixing stability, and without the phenomenon of bolt slippage, which can ensure the stable use of the communication terminal main body, and achieve corresponding The alarm standby state is convenient for inspection and maintenance, so that the main body of the communication terminal is not prone to failure.

In a particular embodiment, a cooling system contains a compressor configured to compress a refrigerant, a high side heat exchanger configured to remove heat from the refrigerant, and a load configured to cool a space using the refrigerant. The high side heat exchanger has a frame and one or more refrigerant tubes extending through the frame, wherein each refrigerant tube has at least one cavity configured to allow the refrigerant to flow through the refrigerant tube. The high side heat exchanger is configured to remove heat from the refrigerant as the refrigerant flows through the one or more refrigerant tubes. The high side heat exchanger also has one or more heat pipes contacting the frame that, collectively, bear at least 25% of the weight of the one or more refrigerant tubes, are coupled directly to the frame, and are configured to remove heat from the flowing refrigerant.

The invention provides an efficient passive spent fuel pool cooling system adopting a jet technology, and belongs to the field of nuclear power plant safety. The system comprises a jet subsystem, a heat exchanger inlet pipe section, a water space heat exchanger, a gas space heat exchanger, a heat exchanger outlet pipe section, a chimney and related pipeline values. When the temperature of a spentfuel pool is higher than a warning value, the system puts into operation automatically, air outside a fuel plant is injected through high pressure gas ejected by a high pressure gas storage tank in the jet subsystem, or water inside a water storage tank and air outside the fuel plant are injected at the same time, and powerful driving force is provided for a cooling loop while the total quantity of a cooling fluid is increased. When the water or gas inside the subsystem in the jet subsystem is used up, the system still can form passive natural circulation in virtue of the density difference ofair in cold and hot sections, and long-term cooling is carried out on the spent fuel pool, so that effectively passive cooling of the spent fuel pool in 3 to 6 days or even longer time can be guaranteed in accident conditions and when an external power supply is lost.
