Problems solved by technology

Although the heat dissipation device in this solution solves the problem of the volume of the device, the heat dissipation efficiency is still limited. The maximum running speed of the intercity EMU is only 300km / h. When the running speed of the train is further increased, the increase of the transformer capacity will cause insufficient heat dissipation.

Embodiment Construction

[0038] like figure 1 and figure 2 As shown, a single module of the present invention includes a heat dissipation tube bundle 1 , a high-pressure damping fan 2 and a housing 3 .

[0039] like figure 1 As shown, the heat dissipation tube bundle 1 includes an oil inlet pipe 1-1, an inlet header 1-2, a convective heat exchange tube 1-3, an outlet header 1-4, and an oil outlet pipe 1-5. The oil inlet pipe 1-1 communicates with the lower part of the inlet header 1-2 with both ends closed; the oil outlet pipe 1-4 communicates with the upper part of the outlet header 1-4 with both ends closed. The straight sections of the convective heat exchange tubes 1-3 are connected by equal-diameter 180° elbows, and the two ends are connected with the inlet and outlet headers. Therefore, the combination of multi-standard modules can be flexibly realized.

[0040] like figure 2 As shown, the airflow direction of the high-pressure vibration-reducing fan 2 is perpendicular to the axial directi...

Abstract

The invention provides a high-heat-flux vehicle-mounted transformer heat dissipation module. The high-heat-flux vehicle-mounted transformer heat dissipation module comprises a heat dissipation tube bundle, a high-voltage vibration reduction fan and a shell; a multi-wire spiral groove is formed in the inner surface of a convection heat exchange tube in the heat dissipation tube bundle or a single-head spiral piece or a double-head spiral piece is additionally arranged on the inner surface of the convection heat exchange tube in the axial direction, and the outer surface adopts a light tube or ahigh-frequency welding spiral fin or a single-metal rolling fin or a double-metal composite rolling fin; the airflow direction of the high-pressure vibration reduction fan is vertical to the axial direction of the heat dissipation tube bundle so as to reach an effect of heat exchange enhancement between the inner and outer surfaces of the heat exchange tube, and the heat dissipation quantity of asingle module can reach 100 kW; and serial and parallel combination of multiple modules can be carried out according to the requirements of different heat dissipation quantities, so that high-heat-flux heat dissipation requirements of the high-speed and ultra-high-speed train vehicle-mounted transformers in a limited space can be met.

Description

technical field [0001] The invention relates to the technical field of air cooling heat exchange devices, in particular to a compact high heat flux oil-immersed vehicle-mounted transformer cooling module. [0002] The present invention also relates to a heat dissipation module group formed by combining the above heat dissipation modules. Background technique [0003] With the speed-up of high-speed locomotives and the research and development of ultra-high-speed maglev trains, the speed of which can reach 300km / h to 600km / h, the load of transformers on-board the trains has increased successively, which inevitably brings about high fever during operation. with great damage. [0004] The Chinese patent with the application number 201621150333.3 discloses a radiator scheme for a conventional oil-immersed transformer. The upper butterfly valve in the transformer radiator is connected to the lower butterfly valve, and the upper butterfly valve is connected to the main oil inlet ...
