Abstract

The invention discloses a compact cooling device for a converter. The compact cooling device comprises a multifunctional compact radiator, a water pump, a fan set, a hydraulic-electric integrated quick connector, a multifunctional framework and a pipeline system, the multifunctional compact radiator comprises a first radiator main liquid chamber, a radiator core body, a second radiator main liquidchamber, a radiator auxiliary liquid chamber, a radiator water inlet pipe and a radiator water outlet pipe which are sequentially arranged and form an integrated structure, and the first radiator main liquid chamber and the second radiator main liquid chamber are provided with water inlet pipes or water outlet pipes. An exhaust liquid stabilizing pipe is arranged in the radiator auxiliary liquidchamber, and a two-way pressure regulating valve and a water pump liquid supplementing pipe are arranged on the radiator auxiliary liquid chamber; the fan set is arranged on one side of the radiator core body; the multifunctional compact radiator, the water pump, the fan set and the hydraulic-electric integrated quick connector are arranged on the multifunctional framework and are communicated through a pipeline system. The cooling device has the advantages of simple structure, small occupied space, light weight, compact structure and the like.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of rail transit equipment, in particular to a compact cooling device for a converter. Background technique [0002] At present, the cooling devices of traction converters of most locomotives and EMUs adopt the secondary cooling method of forced liquid circulation + forced ventilation, which is commonly referred to as liquid cooling. The water cooling device adopting the liquid cooling method is mainly composed of a radiator, a fan unit, a pump, an expansion tank, a pipeline, a load-bearing frame, and sensors such as temperature and pressure. The core is transferred to the cooling air through heat exchange; the function of the expansion tank is to exhaust the cooling device, replenish liquid and adjust the pressure; the load-bearing frame provides a supporting structure for the installation of various components of the cooling device; road connection. [0003] In the existing converter w...
