Background technology
At present, in technical fields such as large-scale power-supply devices, need operating frequency at 12-25KHz sometimes, electric current at more than 10000A, power between 30-100KVA, secondary voltage at 5-36V, the transformer of primary voltage between 85-248V; Because the parameter of this kind of transformer is larger, if therefore adopt the mentality of designing of traditional transformer, then the size of transformer can be caused larger, heat dispersion is also difficult to ensure simultaneously; So design and develop the water-cooled high-power low-voltage high-frequency transformer that a kind of volume is little, perfect heat-dissipating, coefficient of safety are high to seem it is particularly important.Thus reduce the volume of large-scale power-supply device.
Utility model content
The technical problems to be solved in the utility model is: provide the water-cooled that a kind of volume is little, perfect heat-dissipating, coefficient of safety are high high-power low-voltage high-frequency transformer.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
The high-power low-voltage high-frequency transformer of a kind of water-cooled, comprises primary coil (3), magnetic core (14), secondary coil (12) and firm banking; Described primary coil (3) is made up of a hollow copper conduit; Described secondary coil (12) is composed in parallel by N root hollow copper conduit; Described secondary coil (12) is around in the outer wall of primary coil (3); Polyurethane film insulating barrier is folded with between primary coil (3) and secondary coil (12); Insulating pad (4) is fixed with between primary coil (3) and the adjacent turn of secondary coil (12); Be welded with wiring copper coin at the two ends of primary coil (3) and secondary coil (12), described firm banking comprises fixing top board (8) and fixing lower platen (15); Be fixedly connected with by four pull bars (13) between described fixing top board (8) and fixing lower platen (15).
Further: described magnetic core (14) is led Ferrite Material by height and made.
Further: magnetic core earth plate (7) is installed on described magnetic core (14).
The advantage that the utility model has and good effect are:
Because the primary coil (3) in the utility model is made up of a hollow copper conduit; Described secondary coil (12) is composed in parallel by N root hollow copper conduit; Therefore coil is conductor on the one hand, also has the function of radiating and cooling on the other hand; So can ensure the heat dispersion of transformer well, and then it is little to have volume compared with the water-cooled transformer of air-cooled or other structures, the advantage of perfect heat-dissipating;
Because secondary coil described in the utility model (12) is around in the outer wall of primary coil (3); Polyurethane film insulating barrier is folded with between primary coil (3) and secondary coil (12); Therefore, it is possible to ensure the insulating properties of transformer well, reduce volume further;
Because secondary coil (12) is composed in parallel by N root hollow copper conduit; Therefore, it is possible to strengthen ampacity well, owing to being welded with wiring copper coin at the two ends of primary coil (3) and secondary coil (12), therefore there is feature easy to install;
Owing to being provided with magnetic core earth plate (7) on described magnetic core (14), therefore effectively electromagnetic interference can be reduced.
