Definitions
- cooling apparatus The invention relates to a cooling device for cooling a semiconductor integrated circuit according to the preamble of claim 1 and a method for cooling a semiconductor circuit according to the preamble of claim 3.
- Electrical or electronic components in particular Leis ⁇ processing circuits, which are configured as a rule by semiconductor switching elements, must be cooled due to their high varnishent ⁇ development during switching operations and in conducting, current-carrying state in general.
- water-cooled cooling boxes are being used, which are called
- Heatsink serve for the semiconductor elements. These cooling boxes can be connected in series or in parallel. With an interconnection in series, the pressure losses accumulate and the cooling water temperature increases from can to can up to a maximum permissible value. In the parallel connection of a comparatively higher flow rate must be gleichmä ⁇ SSIG divided into many cooling boxes. In the published publications ⁇ lichung thyristor valve for the 12-Pulse Converter for the 3 Gorges, 2010 International Conference on Power System Tech- nology, IEEE 978-1-4244-5939-1 / 10, it is suggested by a sophisticated management system, high claimed components to cool more than less stressed elements. In vie ⁇ len semiconductor circuits, however, it is so that the individual semiconductor devices are heavily loaded in different ways over time or be in an idle phase. For this case, both pumps for operating the coolant as well as the coolant flows and the heat ⁇ meleyvorraumen must be designed accordingly that always the maximum heat dissipation can be guaranteed.
- the object of the invention is to provide a coolant device and a method for operating a coolant device that is capable of cooling Of semiconductor circuits to ensure safe and while compared to the prior art, a lower pump power and heat exchanger performance requires.
- the solution of the invention consists in a cooling device for cooling a semiconductor circuit having the features of patent claim 1 and in a method for cooling a semiconductor circuit having the features of patent claim 3.
- the cooling device for cooling an electronic circuit, in particular a semiconductor circuit having a plurality of switching elements, in particular semiconductor switching ⁇ elements, referred to as the semiconductor switching elements ⁇ net, has the following characteristics: Firstly, the cooling ⁇ device comprises a plurality of heat sinks, each having the half ⁇ conductor switching elements are in thermal communication. Furthermore, the cooling device has a coolant distributor device for distributing coolant to the heat sinks.
- the invention is characterized in that ademit ⁇ telhneregelung is provided for variable control of coolant sub-streams. Furthermore, there is a data connection between this coolant flow control and the electronic circuit, in particular the semiconductor circuit for information transmission of load conditions of the switching elements.
- any switching elements electronic components are understood, in particular integrated circuits, thyristors, FET or IGBT may include, but ⁇ Kunststoffliche semiconductor switches, etc. be used.
- a plurality of different semiconductor switching elements or components can be used in a semiconductor circuit.
- the term heat sink is understood to mean bodies which are suitable for dissipating heat and through which the coolant flows or flows.
- the cooling bodies are configured with semiconductor switching elements in the form of cooling cans which are traversed by the cooling medium.
- the cooling boxes or heatsinks in general are furthermore in thermal connection with the semiconductor switching elements or the electronic components.
- the component or the switching element is connected as closely as possible to the heat sink, and that, for example, a thermally conductive paste is used to connect these two elements. It may also be such that a semiconductor switching element between two heat sinks or cooling boxes or a heat sink between two semiconductor switching elements is embedded similar to a sandwich construction. Thus, a plurality of cooling boxes and semiconductor switching elements can be alternately joined together, so that one field
- the term loading conditions is understood to what extent the semi ⁇ conductor switching element is at a certain time, which may be in the future, in use. By determining the load condition, conclusions can be drawn about the absorbed heat of the semiconductor switching element and the resulting temperature of the component and adapted accordingly to coolant flows.
- the advantage of the described cooling device is that it can react to load conditions of the semiconductor switching elements va ⁇ riabel and that the cooling device is designed so that the partial currents that lead to the individual cooling boxes and thus to the individual semiconductor switching elements are adjusted so that they can dissipate the heat arising from the components as needed.
- a multi-way valve is used in the coolant distribution device for this purpose.
- This multi-way valve can be electronically, electromechanically, hydraulically or pneumatically controlled by the coolant flow control.
- a further component of the invention is a method for operating a cooling device having the features of patent claim 3. This method achieves the same object as the cooling device per se and has substantially the same advantages already mentioned with respect to the cooling device.
- Figure a schematic representation of a cooling device for cooling semiconductor switching elements with cooling boxes.
- a cooling device 2 for cooling a semiconductor circuit 4 with individual semiconductor switching elements 6 and heat sinks, which are configured in the form of cooling boxes 8, shown.
- a coolant distributor device 10 which comprises a multi-way valve 11
- a coolant 12 which flows through a coolant line 22 is subdivided by way of example into three partial streams 18.
- This part ⁇ streams 18, 18 ⁇ and 18 ⁇ ⁇ and the cooling means 12 can fundamentally ⁇ additionally to individual cooling cans 8, which are thermally connected to the semiconductor switching elements 6 in combination, are directed or can be directed to panels 26 of switching elements 6 and heat sinks 8 , Before such a field 26, which is not explicitly shown here, a further cooling ⁇ medium distribution device may be provided in a subordinate form.
- the cooling lines 18 are statically, connected in parallel on cooling boxes 8 of the individual ⁇ nen fields 26 divided.
- the cooling boxes 8 can also be connected in series with respect to the coolant partial flow 18 be, which is not shown here.
- This series connection can be advantageous according to the allowed or planned switch-on of the semiconductor elements.
- two fields 26, which may not be simultaneously conductive at the same time can be statically connected in series.
- the coolant 12 is not fed back into the circuit via a heat exchanger 20 and the coolant distribution device 10, but instead is replaced by fresh, cool coolant.
- a data connection 16 is provided which extends from the semiconductor circuit 4 in general, in particular from different fields 26 of the semiconductor circuit 4 or a higher-level control device of the semiconductor circuit 4, not shown here, to a coolant flow control 14.
- the illustration in the present figure is to be seen here merely by way of example, it is to be described that information about operating states or load states of the semiconductor switching elements is transmitted to the coolant flow control 14 itself from the semiconductor circuit.
- this information can be implemented by the coolant flow control 14 in such a way that the partial flow 18 against the partial flow 18th ⁇ and 18 ⁇ ⁇ is increased.
- a control signal is issued from the coolant flow control ⁇ 14 to the coolant distribution device 10, which in turn has a direct effect on the multi-way valve 11 and the passage leading to the partial flow 18 is opened relative to the partial flow 18 ⁇ and is opened further and a higher Flow of coolant 12 into the partial flow 18 takes place.
- a not shown secondary coolant distributor device may be arranged before the distribution to the field 26, which in turn individual semiconductor elements 6 or the cooling boxes 8, which belong to the individual ⁇ NEN semiconductor elements 6, flows through correspondingly stronger or weaker with the coolant 12 become.
- each individual semiconductor switching element 6 can be selectively addressed. It may also be expedient for information to come from the semiconductor circuit 4 to the coolant flow control 14, the load or the expected load of the individual semiconductor switching elements 6 or of whole fields 26 in the current state and in closer, to be defined or fixed future include.
- the coolant flow control 14 the coolant distribution device 10 control such that specifically this semicon ⁇ conductor switching element or this field 26 or 26 ⁇ and 26 ⁇ ⁇ is flowed through with the coolant 12 and thus pre-cooled.
- the heat sink or the cooling boxes 8 are thus replaced by the proposed cooling device.
- the described coolant device or the described method for cooling a semiconductor circuit in this case has the advantages that overall a lower Energybe ⁇ may exist for cooling water pumps. Furthermore, the device described leads to lower thermal stress of the semiconductor switching elements 6, when the end of the load, ie at the end of the operation, the cooling is turned off. Thus, the semiconductor switching element is not shock-cooled down to the cooling ⁇ water temperature. Further, it is advantageous if the formation of Todwasser by substances can concentrate itself, which increase the conductivity of the cooling medium around ⁇ is prevented by frequent regular switching of the various substreams.
