Abstract
The utility model provides an insulated gate bipolar transistor (IGBT) module radiator of a middle-frequency power supply, which comprises a panel, a water tank, a water inlet and a water outlet. A plurality of partition plates are arranged inside the water tank at equal intervals. One sides of the partition plates are connected with the bottom of the water tank, gaps are reversed between the other sides of the partition plates and the panel, and the partition plates are connected with an inner wall of the water tank. Due to the fact that an inner cavity of the water tank is divided into a plurality of channels, cooling water is easy to pass through the radiator evenly, air is not easy to detain, contact area between the cooling water and the IGBT module radiator is increased, and a radiating effect is effectively improved.
Description
Technical field
The utility model relates to a kind of radiator of intermediate frequency power supply, relates in particular to a kind of IGBT module heat radiator of intermediate frequency power supply.
Background technology
Intermediate frequency power supply is a kind of static frequency-conversion device; Three phase worker power is transformed into single phase poaer supply, is mainly used in the melting, insulation, sintering, welding, quenching, tempering of various metals, diathermanous, molten metal purification, heat treatment, bend pipe and crystal growth etc.
The intermediate frequency power supply that adopts the IGBT module in the course of the work, the IGBT module can produce a large amount of heats, if the IGBT module can not get cooling off quickly, the danger of being burnt is just arranged, and in the prior art, generally all adopts radiator to the cooling of dispelling the heat of IGBT module.
IGBT module heat radiator of the prior art generally all is through the water-cooling pattern cooling, reduces the temperature of IGBT module through current; But current problems such as the cooling water circulation is smooth, air alluvial often occur when the radiator, cause that the radiator cooling effect is undesirable, heat radiation is inhomogeneous; Make the on-off action variation of IGBT module; The probability that IGBT module temperature is too high to be caused burning is very high, in case burn, maintenance cost is very high.
The utility model content
The utility model is in order to solve poor, the uneven problem of dispelling the heat of IGBT module heat radiator cooling effect in the prior art, a kind of IGBT module heat radiator that improves cooling effect, the uniform intermediate frequency power supply of heat radiation to be provided.
In order to address the above problem; The IGBT module heat radiator of a kind of intermediate frequency power supply that the utility model provides comprises panel, water tank, water inlet and delivery port; The inner equidistance of said water tank is provided with several dividing plates; Said dividing plate one side links to each other with water tank bottom, leaves the space between opposite side and panel, and said dividing plate links to each other with tank inner wall.
The effect of dividing plate is that water tank cavity is separated into several passages; Be convenient to cooling water and pass through radiator uniformly, and the water tank inside of radiator is not easy air entrapment, because the existence of dividing plate; Increase the contact area of cooling water and IGBT module heat radiator, effectively improved radiating effect.
As preferably, said water tank bottom and dividing plate are structure as a whole, and the spacing of dividing plate is 8～15 millimeters.Make the radiator internal structure more reasonable, improve radiating effect.
As preferably, the space of said dividing plate and panel distance is 2～5 millimeters.It is unobstructed to be convenient to current, and air can not deposit.
The utility model adopts technique scheme, obtains following beneficial effect:
1, compared with prior art, the water tank inside of the IGBT module heat radiator of the utility model has increased the dividing plate that equidistance is provided with, and makes cooling water to flow through radiator uniformly, reaches the heat radiation effect of uniform.
2, dividing plate has increased the contact area of radiator and cooling water, when cooling water flows through radiator, can take away more heat, has improved cooling effect.
3, dividing plate and water tank bottom are structure as a whole, and are convenient to processing, and the space of dividing plate and panel makes cooling water flow unobstructed, and unobstructed current can be taken away the air of delay, reduce the factor that influences radiating effect, improve cooling effect.

Embodiment
Fig. 1, Fig. 2, shown in Figure 3; The IGBT module heat radiator of intermediate frequency power supply comprises rectangular panel 1; Panel 1 thickness is 8～10 millimeters, and the one side of panel 1 is welded with water tank 3, and the both sides of panel 1 another side are respectively arranged with several water inlets 51 and delivery port 52; Water inlet 51 communicates with water tank 3 inside with delivery port 52, and the number of water inlet 51 and delivery port 52 is by the size decision of water tank 3.Panel 1 and water tank 3 are processed by aluminum material, and heat conductivity is good, is convenient to heat radiation.
In conjunction with Fig. 4 and Fig. 5, water tank 3 inside equidistance successively are provided with several dividing plates 7, and the quantity of dividing plate 7 is determined by water tank 3 interior size.Dividing plate 7 is rectangular aluminum making sheet, and dividing plate 7 one sides link to each other with water tank 3 bottoms, and 1 of opposite side and panel leave space 9, and dividing plate 7 upper/lower terminals link to each other with water tank 3 inwalls.The effect of dividing plate 7 is that water tank 3 inner chambers are separated into several passages; Be convenient to cooling water and pass through radiator uniformly, and the water tank inside of radiator is not easy air entrapment, because the existence of dividing plate 7; Increase the contact area of cooling water and IGBT module heat radiator, effectively improved radiating effect.
Preferably, water tank 3 inside equidistance successively are provided with several dividing plates 7, and water tank 3 is structure as a whole with dividing plate 7; Form by monoblock aluminum material turnning and milling; The spacing of per two dividing plates is 8～15 millimeters, improves the heat radiation uniformity, and the quantity of dividing plate 7 is determined by the water tank interior size.
1 of dividing plate 7 and panel leave 2～5 millimeters space 9, are used for cooling water and inject the passage that dividing plate 7 forms, and in passage, form boiler water circulation, discharge radiator behind the absorption heat.
Adopt the IGBT module heat radiator of the intermediate frequency power supply of this kind structure, cooling water injects water tank 3 by water inlet 51, has dividing plate 7 to intercept in the water tank 3 and forms some passages, and cooling water circulates in passage, with the heat absorption on panel and the water tank.Because the existence of dividing plate 7; Making the water tank inner space compared with prior art have obviously dwindles; Quickening cooling water circulates in water tank 3; Dividing plate 7 has increased the contact area of cooling water and water tank 3 again simultaneously, and the more heats that absorb quickly of cooling water are discharged by delivery port 52 again, has improved the radiating effect of the IGBT module heat radiator of intermediate frequency power supply effectively.
