Definitions
- the invention relates to a housing for a converter, in particular a DC power converter, for example a DC / DC converter, with which a first voltage can be converted into a second voltage, with a metal casting and at least one line for a heat carrier.
- the invention also relates to a converter with such a housing and a method for producing such a housing.
- a housing with an aluminum die-cast part and a line made of a steel pipe is known.
- the line is enclosed by the die-cast aluminum part. This is achieved by placing the steel pipe as an insert in a casting mold for producing the aluminum die-cast part, before the mold is filled with the liquid aluminum.
- the housing of a converter known from document DE 102016 119303 A1 has the advantage that heat that arises when the converter is operated by power semiconductors can be absorbed by the cast metal part of the housing and effectively dissipated via a heat transfer medium flowing in the line.
- the line is routed through the cast metal part at a point that is close to one of the power semiconductor components in which the heat is generated when the converter is operated.
- branches or junctions in the line can only be provided in a very complex manner in order to produce a line system via which the heat transfer medium can be guided in parallel to different points of the housing. So that the heat transfer medium can be routed to different points of the housing in parallel, the line must have branches and junctions or several lines would have to go through the metal casting are performed, which are then brought together outside of the metal casting.
- the line is formed by a line part which has a plastic part and a metal plate.
- the plastic part can be a plastic injection molded part.
- the metal plate can be a sheet metal part. At least part of the line can be provided in the plastic part. This part is an incomplete line part that is not able to carry a heat transfer medium.
- the metal plate can complete this at least part of the line to form a line in which the heat carrier can flow.
- the heat carrier can be a cooling liquid, in particular water.
- the plastic part has at least one channel and the metal plate forms a cover with which the channel is covered.
- the channel covered with the cover can then form the at least one line.
- the channels can be easily produced in the plastic part during production. If it is a plastic injection molded part, the channels can be provided as a negative in the injection molding tool. This can be useful if the line part is manufactured in large numbers. If a line part is only to be manufactured in small numbers or even as a single piece, the line or lines can be manufactured in a plastic body by milling.
- the metal plate used as the cover can be made from sheet metal by punching, sawing, shearing, laser cutting or another suitable separation process. It is not necessary for a metal plate used as a cover to have protruding or recessed structures. Also, no holes need to be provided in the tallplatte Me. The metal plate can therefore be easily manufactured.
- the plastic part can have several channels. Each channel can have branches and / or junctions via which the channels can be connected to one another. This also makes it possible to create complex lines in the line part, with which the heat transfer medium can be performed at different points in the Ge housing at the same time in order to dissipate heat from these points at the same time.
- the heat transfer medium can be led to these points without having previously been passed over other parts of the housing and there has already been heat stampnom men, whereby the ability to absorb heat due to a temperature increase of the heat transfer medium has already been reduced.
- the plastic part of a housing according to the invention can have at least one basin into which one or more channels open or at which one or more channels begin.
- This basin can be covered by the lid. That through Basin covered by the lid can form a chamber which is connected to the at least one conduit. This chamber can be easily seen at a point on the housing where a cooling load is required over a large area.
- the line can have an inlet and an outlet, via which the line can be connected to a feed line for the heat carrier and a forward line for the heat carrier.
- connection structures can be provided in particular in the plastic part of the line, which are used to connect between the line part and the supply or forwarding line.
- Such a connection structure can be, for example, a threaded hole which is connected to the channel or to one of the channels in the plastic part.
- Such a housing can be part of a converter and in particular accommodate power electronic components of a converter, in particular the power semiconductors.
- the housing protects the components against environmental influences, for example against moisture, dust and dirt.
- the components of the converter can thus be encapsulated from the environment.
- the converter housing it is possible with the converter housing to effectively dissipate the heat generated during operation of the converter.
- the converter can be a DC converter, in particular a DC / DC converter, with which a first voltage can be converted into a second voltage.
- the plastic part and the metal plate must be produced and joined together to form the line part, the metal plate covering the channels provided in the plastic part.
- the line part can then be used as an insert part in a casting mold, which is then filled with a liquid metal, in particular aluminum or an aluminum alloy. After removal from the mold, the composite of the metal casting and the line part can be reworked if necessary in order to complete the manufacture of the housing. It can be possible be that no post-processing is required. After the usual deburring and cleaning, the composite can be used without a tool.
- FIG. 2 shows a line part made from a plastic part and a metal plate
- FIG. 3 shows a housing part comprising the line part and the metal casting.
- the figures of the drawing show only one possible embodiment with an O-shaped cooling circuit.
- the invention allows any course of the cooling circuit, as long as a plastic part can be closed with a metal cover corresponding to the contour. This enables, for example, I-, L-, U-shaped as well as wave and zigzag courses as well as several changes of direction of the cooling circuit.
- the plastic part 1 has by and large the shape of a rectangular frame mens.
- This frame In an upper side of this frame several channels 10 are formed, which are separated from one another by webs 11 and connected to one another by branches and junctions.
- the channels 10 form a channel system which has an inlet basin 12 and an outlet basin 13.
- the inlet basin 12 and the outlet basin 13 are separated from one another by a web 14.
- the webs 11, 14 are slightly retracted relative to an inner side wall 15 and an outer Be tenwand 16 of the plastic part, ie the webs 11, 14 jump ge compared to the side walls 15, 16 back slightly.
- the cover 2 is a perforated, also frame-like metal plate which has been produced by punching from a metal sheet.
- the cover 2 covers the channels 10, the inlet basin 12 and the outlet basin 13. This creates from the Channels 10 lines, an inlet chamber from the inlet basin and an outlet chamber from the outlet basin.
- the plastic part 1 has an inlet connection 17 and an outlet connection 18 to which a supply line and a continuation line can be connected.
- This Stut zen 17, 18 are arranged on the underside of the frame.
- the inlet port 17 is connected to the inlet chamber and the outlet port 18 is connected to the outlet chamber.
- the plastic part 1 and the cover 2 together form the line part, which is arranged as an insert part in a casting mold.
- the mold is then filled with liquid aluminum and the cast metal part 3 is in a solid bond with the line part 1, 2.
- this composite then forms the part of the housing according to the invention shown in Figure 3.
