Abstract
The utility model discloses a high-air-impermeability connection device for a power module water cooling plate and a water pipe, and aims at providing a high-air-impermeability connection device for a power module water cooling plate and a water pipe, and the connection device is simple in structure, convenient in manufacturing and mounting, reliable in use and good in sealing property. The high-air impermeability connection device for the power module water cooling plate and the water pipe comprises the power module water cooling plate, wherein a water delivery hole is arranged on the water cooling plate and communicated with a circulating water channel. The high-air-impermeability connection device for the power module water cooling plate and the water pipe is characterized in that a deep pit is arranged at the mouth of the water delivery hole; an inner thread is arranged at the mouth of the deep pit; an elastic sealing ring is arranged at the bottom of the deep pit; a flange which is flanged outwards and matched with the deep pit is arranged at the mouth of a water delivery pipe which is connected with the water cooling plate; and a compression nut which presses the flange is screwed on the inner thread so that the front end face of the flange and the bottom of the deep pit are tightly compressed to implement end face sealing. According to the utility model, the compression nut is used for compressing and positioning the water delivery pipe, so that the advantages of good sealing property, convenience in mounting and reliability in use are provided and the defect that the quality is not easy to guarantee due to welding is avoided.
Description
Technical field
The utility model relates to cooling unit, relates in particular to the high airtight connection set of a kind of inverted power module cooled plate and water pipe.
Background technique
The High power Traction convertor equipment is widely used in occasions such as high-speed railway transportation, urban track traffic.The high power contravariant power model is directly born the task that reliable inversion power supply is provided for traction electric machine as one of core component of High power Traction convertor equipment.This power model is made up of high-power IGBT device, lamination power generatrix, water cooler, filter capacitor, opto-electric connector, DC electrical source and structural support.Owing to can produce great amount of heat during the work of IGBT device; Therefore need the water cooler cooling, the common type of cooling is that the IGBT device is installed on the cooled plate, and the centre of cooled plate is shaped on the circulation water channel; Be connected with the turnover water pipe joint above; Connect water-cooling tube in the water pipe adapter, utilize cooling water the heat on the IGBT device to be conducted to cooled plate and take away, reach cooling purpose through cooled plate.Common cooled plate is to be processed by aluminum material, and the water-in and water-out pipe joint of the aluminium matter mode through welding connects and seals.Because aluminium material surface has oxide layer, it is fast to conduct heat, and when welding, slag inclusion and crackle takes place easily, the traditional hand weldering, and general welder technology is difficult to guarantee welding quality.And the reliability of this power model is high, must definitely guarantee welding quality.
The content of model utility
The purpose of the utility model provide a kind of simple in structure, manufacturing and easy for installation, use power model cooled plate and the airtight connection set of water pipe height reliable, good seal performance.
In order to reach above-mentioned requirements; The utility model is realized through following scheme: it comprises the cooled plate that power model is used, and is shaped on water hole on the cooled plate, and water hole is communicated with the circulation water channel; It is characterized in that being shaped on heavy hole in the water delivery aperture; The aperture in heavy hole is shaped on internal thread, and the bottom in heavy hole is equipped with flexible seal ring, and the water delivery mouth of pipe that is connected with cooled plate is shaped on heavy hole and matches to the flange that turns up; On internal thread, be rotary with the gland nut of pushing down flange, make the front-end face of flange and seal ring end face closely compress the enforcement end face seal with the end, heavy hole.
Described seal ring is processed with teflon.
Power model cooled plate and the high airtight connection set of water pipe according to the such scheme manufacturing; Rely on gland nut to compress and conduit pipe is located; Have good seal performance, easy for installation, a service-strong advantage, avoided because the welding institute quality of bringing is difficult for the shortcoming of assurance.
Description of drawings
Fig. 1 is the high airtight connection set structural representation of power model cooled plate and water pipe.
Among the figure: 1, cooled plate; 2, water hole; 3, circulation water channel; 4, heavy hole; 5, internal thread; 6, seal ring; 7, conduit pipe; 8, flange; 9, gland nut.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe.
Fig. 1 is the structural drawing of the airtight connection set of power model cooled plate and water pipe height.From figure, find out; It comprises the cooled plate 1 that power model is used, and is shaped on water hole 2 on the cooled plate 1, and water hole 2 is communicated with circulation water channel 3; Be shaped on heavy hole 42 mouthfuls of water holes; The aperture in heavy hole 4 is shaped on internal thread 5, and the bottom in heavy hole 4 is equipped with teflon processes flexible seal ring 6, and the conduit pipe that is connected with cooled plate 1 is shaped on heavy hole 4 for 7 mouthfuls and matches to the flange that turns up 8; On internal thread 5, be rotary with the gland nut 9 of pushing down flange 8, make the front-end face of flange 8 and seal ring 6 end faces closely compress the enforcement end face seal with 4 ends of heavy hole.
Claims (2)
