摘要： In a method for cooling an MRI apparatus, and an MRI apparatus, the MRI apparatus has a magnet, a primary cooling device and a secondary cooling device, and a magnet controller, the primary cooling device being in contact with the magnet and the secondary cooling device separately. The magnet controller continuously monitors a pressure of the magnet, and turns off the secondary cooling device if the pressure is greater than or equal to a first preset pressure, of less than a second preset pressure and in a rising state. The present invention can save electricity, and since the duration of use of the secondary cooling device is also reduced, the lifespan of the secondary cooling device is prolonged, saving costs.

摘要： A wireless charging coil structure with a function of heat dissipation comprises a first connecting terminal, a second connecting terminal and a coil. The coil is disposed between the first connecting terminal and the second connecting terminal, and configured to transmit a signal between the first connecting terminal and the second connecting terminal. The coil comprises a heat-pipe segment and a transmission segment electrically and heat-conductively connected with each other. The transmission segment has a predetermined thickness, the heat-pipe segment encircles an accommodating space, and a heat-dissipating medium is disposed in the accommodating space.

摘要： Systems and methods for liquid heat exchange for transformers are described. One embodiment of a fluid heat exchanger includes a transformer inlet port that is coupled to a transformer chamber and receives a dielectric fluid from the transformer chamber. Also included are a cooling fluid inlet for receiving a cooling fluid and a finned heat sink that includes a fluid communicator. The fluid communicator may receive, at a first chamber, the dielectric fluid from the transformer inlet port and directs the dielectric fluid across a first plurality of cooling fins. The fluid communicator may receive, at a second chamber, the cooling fluid from the cooling fluid inlet and may direct the cooling fluid across a second plurality of fins, where the fluid communicator separates the first chamber from the second chamber with a solid divider.

摘要： A copper tube with copper end pieces for a water-cooled secondary winding of a welding transformer is an example of a brazed assembly having a potentially corrodible side, the water-cooled side, and a low-exposure side, the air side or dry side, of the joined pieces. By shaping contacting surfaces of the parts at the brazed joint it is useful to form a barrier, for example, between a special braze material required for the corrosive side and a conventional, easy to apply, braze material for use on the air side of the joint.

摘要： A high frequency water cooled transformer for coupling a power source to an induction heating coil and which serves to convert the output of the power source into values appropriate for the induction heating coil, and to match the impedance of the power source with the impedance of the heating coil for maximum power transfer efficiency. The primary of the transformer is adapted to be connected to the power source and the secondary is adapted to be connected to the induction heating coil. The transformer includes a secondary formed of two parallel self-supporting elongated open-ended electrically conductive cylindrical members which are separated and insulated from one another. A pair of electrically conductive terminal blocks are respectively mounted on one of the ends of the cylinders and electrically connected to the cylinders. The primary winding is wound longitudinally through the two secondary cylinders, and the ends of the primary are connected to appropriate terminal pins. Each of the cylindrical members has an internal sleeve which defines an annular passage through the corresponding cylindrical member, and means is provided for circulating a coolant through the cylindrical members and through the terminal blocks. Each secondary cylinder is surrounded by a plurality of ferrite toroid cores, and the assembly is potted so that the cores, the secondary cylinders and the primary windings are all sealed to one another by heat conductive potting compound.

摘要： A transformer for a welding gun has a reduced resistance and reactance thus drawing less current. The transformer is of substantially reduced weight and may be operated at high duty cycles and in a welding gun performing a large number of welds per hour. The transformer is formed of a hollow coil and coolant is flowed through the coil to directly cool the primary. The secondary is electrically insulated from the primary but physically adjacent the primary so that heat from the secondary is dissipated through the primary to the contact.
