Technical field
The utility model relates to a kind of water-filled radiator of high-power insulated gate bipolar transistor IGBT module, especially relates to a kind of IGBT module open type water-filled radiator.
Background technology
At present, generally use the insulated gate bipolar transistor IGBT module on the high-power converter, the same with other power electronic device, because switching loss and on-state loss are inevitable, the IGBT module in use can produce a large amount of heats, if untimelyly effectively these heats are shed, the temperature of IGBT module raises will influence the performance of power, overtemperature even can directly cause the thorough damage of IGBT module.
The traditional heat dissipating method of power electronic device generally there are multiple measures such as air-cooled, oil cooling and water-cooled.Shortcomings such as and that air-cooled and oil cooling exists radiating efficiency is low, and the radiator volume is big, and weight is big, wherein oil cooling also exists the leakage pollution problems.Present employing water-cooling pattern, its water cooler generally itself seals, and cooling water comes the cooling power electronic device by the cooling water cooler, and heat exchange efficiency is general, and volume and weight is still bigger, is unfavorable for installing and maintenance when being applied in many IGBT modules parallel connection occasions.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, provide a kind of IGBT module open type water-filled radiator, its compact conformation, radiating efficiency height, reduced the volume and weight of radiator as much as possible, and be convenient to produce and maintenance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: water-cooling spare, admitting pipe joint and titting water outlet, it is characterized in that: described water-cooling spare is the open type slab construction, and its open surface is provided with winding type current groove, the bottom of described current groove has water inlet and delivery port, and described admitting pipe joint and titting water outlet are installed on described water inlet and the delivery port respectively and all are positioned at the outside of water-cooling spare; On the open surface of water-cooling spare, and be positioned at the current groove around be provided with the groove that is used to install sealing ring.
Described water inlet and delivery port lay respectively at the two ends of current groove.
Described water-cooling spare is provided with the temperature element installing hole.
Described water-cooling spare is provided with the threaded mounting hole that is used for fixing the IGBT module.
The utility model compared with prior art has the following advantages: because water-cooling spare is taked the open type slab construction, IGBT module heat dissipating face directly contacts with cooling water, so heat exchange more directly fully, the radiating efficiency height, reduced the volume and weight of radiator as much as possible, and be convenient to produce and maintenance.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
