This invention relates to the field of magnetic levitation chiller technology and discloses an energy-saving variable frequency magnetic levitation chiller, including an evaporator, a condenser installed at the bottom of the evaporator, a connecting seat fixedly mounted at the end of the condenser, and a flow guiding component on the outer wall of the connecting seat. This energy-saving variable frequency magnetic levitation chiller recovers waste heat from the condenser cooling water to perform closed-loop constant temperature control on the magnetic levitation bearing, ensuring the bearing remains within its optimal operating temperature range. This avoids coil resistance drift, sensor temperature drift, and fluctuations in levitation stiffness under low-temperature conditions, improving the operational stability of the magnetic levitation bearing. Utilizing the residual heat of the heated cooling water for constant temperature treatment of the magnetic levitation bearing eliminates the need for additional electrical energy consumption for preheating and insulation. Building upon the inherent high efficiency and energy saving of magnetic levitation technology, this further reduces auxiliary energy consumption and improves overall energy efficiency.

The utility model belongs to the technical field of data acquisition equipment, and particularly relates to wide-frequency-band data acquisition equipment with variable sampling rate, which comprises an equipment main body, anti-slip strips, bolts and a power supply connecting port, the anti-slip strips are arranged on the outer end surfaces of the left side and the right side of the equipment main body, and the bolts are arranged on the outer end surface of one side of the rear end of the equipment main body; the power interface is arranged on the surface of one side of the rear end of the equipment body. Through the arrangement of the heat dissipation grooves, the heat dissipation fan blades and the power supply connecting port, when the equipment works, if the environment temperature is high, the working environment temperature in the equipment continuously rises, the heat dissipation fan blades are opened and start to rotate, the heat dissipation fan blades drive air to circulate, and the air is transferred to the outside through the heat dissipation grooves; and meanwhile, the temperature in the equipment main body is reduced, so that the equipment main body is kept at a relatively low operating temperature, and the equipment has an active heat dissipation effect through the arrangement, so that the equipment is prevented from being overheated and damaged due to over-high environment temperature.
