Definitions
- the invention is concerned with the cooling of chokes and transformers according to Claim 1.
- the device should as effectively as possible the heat from the surface record and dissipate and at the same time simple and inexpensive to produce, possibly even be retrofitted, be.
- the invention solves this problem u.a. in that at least one surface of a Body, for example, the iron core of a mains choke or a transformer, is brought into operative connection with a heat exchanger. This is the Heat dissipation guaranteed directly from the surface and is by means of the Heat exchanger, which is flooded by a cooling fluid, continuously dissipated.
- the Heat exchanger only one heat absorber and one with the heat absorber in Active connection standing cooling fluid guide comprises, so the overall arrangement more or less consists of only two main components. These Two-component arrangement can also later on the surface heat-absorbing components are attached or placed.
- the cooling can Therefore, be considered as a modular system, which is not to a certain component is bound or in the construction of a component necessarily to be considered.
- the heat absorber is a guide plate, preferably a metallic one Plate, in particular made of copper.
- This will be a large area Heat transfer guaranteed, provided the entire surface with the heat radiating Surface of the component component is in operative connection.
- the cooling fluid guide preferably by means of a channel is realized, wherein the channel is formed as a columnar hollow body and at least in the area of the active compound with the absorber a square or has rounded cross-section.
- the fluid can then be targeted and independent of the spatial position of the heat exchanger by means of a suitably sized Pressure to be transported to the heat sources.
- An angular cross section increases the Contact surface between fluid guide and absorber.
- a round cross section is cheaper to purchase.
- the invention is suitable for use on at least one iron core and / or a mains choke, in particular the mains choke of a regenerative Inverter (eg converter series SFT from Indramat Refu GmbH with sinusoidal Feedback).
- Mains chokes have very high currents (around 600 amps) to process and have relatively high inductances (around 180 ⁇ H). Due to the ohmic Resistance of the windings, either from single wires or even out Copper plates or copper bars, these chokes develop one high heat loss. This heat loss can, if it is not dissipated, too Damage to the insulation and cause business interruptions and according to subsequent costs entail.
- the device according to the invention possibly also Depending on a particular application, attach later or produce these risks and eliminate unnecessary costs.
- the same benefits would come with transformers or others electrical components, provided the same concept for cooling purposes would be used.
- Fig. 1 shows a first embodiment of the invention and in detail a Heat exchanger 14 with copper plate 12, a meander-shaped cooling coil 13 with 90 ° bends 13a, 180 ° bows 13b, terminal lugs 13c and straight elements 13d and an iron core 11 and winding packages 10th
- the line reactor of an inverter shown here comprises three components Copper windings 10 are penetrated by three iron core legs 11. Of the Iron core itself is used for channeling the forming during operation magnetic River. At the two end faces of the arrangement is in each case an inventive Cooling device 14 attached.
- the copper plate 12 can be seen and the Coolant guide 13, which makes sense from a variety of Single components (13a, 13b, 13c, 13d) is formed.
- the individual components can soldered or welded together.
- the coolant guide 13 is meander-shaped soldered or otherwise attached to the copper plate and transports the iron core 11 emitted and absorbed by the heat absorber 12 Heat off. Both heat exchangers 14 could be connected in parallel or in series via a Pump be supplied with liquid coolant.
- the coolant flows through with a From the pressure and cross section dependent force the cooling system and leads the over the Absorber or the pipe walls 13, 13a, 13b, 13c absorbed heat effectively from.
- the heat absorber also radiates additional heat over its surface to the environment. By enlarging this surface, e.g. by means of ribs, An additional cooling effect could be effected.
- FIG. 1 shows with the Fig. 1 largely identical components 10, 11, 12, 13, 13a, 13b.
- the difference from Figure 1 is that the heat exchanger now not to the End faces of the iron core 11 are mounted, but on the upper and lower sides and partially within the iron core encompassed by the copper coil.
- the sewer system 13 of the coolant is U-shaped, connecting piece 13c are not shown here.
- the lines 13 are shown here with a round cross-section, the support surface on Absorber 12 is thereby smaller than in a rectangular cross-section. Therefore would be to favor a rectangular cross section or the line 13 should be at least partially embedded in the absorber surface.
