It is also known to couple a radiator and an air conditioning condenser to form an assembly.

The cooling module 1 is composed of a mechanically produced coolant cooler 2 and a soldered condenser of fully-aluminum design.

All-aluminum radiators, heater cores and power-steering oil coolers are produced for passenger cars, and radiators are produced for utility vehicles.

As a result of the flexibility achievable with such an arrangement when adjusting the cooling capacity to the actual operating status and the actual cooler requirements, such a coolant cooler can be used for a multitude of standard types of gas turbine.

Precisely when used in a gas and steam turbine, the coolant cooler designed as a forced throughflow steam generator contributes the relatively high efficiency achievable when using the heat produced during cooling of the coolant of the gas turbine in a particularly advantageous manner to a destination usually specified in any case in the design of a gas and steam turbine.

The two coolant streams can thus be brought together, it being possible to discharge the waste heat from the cooling circuit to the heating circuit when the coolant radiator is separated from the coolant circuit.

The coolant cooler is also particularly suited to what is known as solo operation in which no further use is made of the generated steam in an assigned steam turbine plant.

FIGS. 1 to 3 illustrate an arrangement comprising a charge air cooler 1 and a coolant radiator 2 which are both fixedly connected with one another.

It may be mentioned here that the collecting tanks 3, 4, 5 and 6 of the charge air cooler and of the coolant radiator 2 are made of plastic and that all parts described up to now, including the snap bracket 21 or the pins 9 and 10, are also made of plastic.

The coolant cooler designed as a heat exchanger to this effect can be designed secondarily as a low-pressure steam generator in which a flow medium evaporates and the steam thus generated is fed into the water-steam circuit of a steam turbine or is also supplied to a district heating network to recover the energy.

Precisely in such a multistage design of the water-steam circuit of the steam turbine, a particularly effective use of the heat produced during cooling of the coolant of the gas turbine is made possible by adjusting the coolant cooler for supplying relatively high-quality steam to the highest pressure level of the multistage water-steam circuit of the steam turbine.

In the process, the steam generated in the coolant cooler can, for example, be fed into a high-pressure drum or in the event that the waste heat steam generator is also designed as a forced throughflow steam generator in the high-pressure range, into a high-pressure separator vessel.

The invention relates to a coolant circuit for an internal combustion engine, with a coolant radiator, at least one mechanical coolant pump and at least one electrical coolant pump for a cooling circuit having a coolant inflow and for a heating circuit having a coolant return, in each case with at least one heat exchanger, the mechanical coolant pump and/or the electrical coolant pump being assigned to the heating and/or cooling circuit, and the mechanical pump being capable of being cut in and cut out or of being throttled.

Via a coolant inflow 13 of the valve 6, the coolant stream which occurs is transferred, via a coolant outflow 14 ? of the valve 6, into the coolant inflow 8 of the mechanical coolant pump 3 and of the electrical coolant pump 4, and/or, via a coolant outflow 14 of the valve 6, into a coolant radiator 2 designed as an air radiator.

A cooling module, which is arranged in the front engine space of the motor vehicle, conventionally comprises a coolant radiator, a charge air cooler and/or a condenser, which are fastened to one another and thus form a modular unit.

Coolant radiators are constructed differently than refrigerant condensers and often have a soldered network with soldered tube plate and a coolant tank which is produced as a plastic injection-molded part and thus offers the opportunity to integrally injection-mold coolant pipe stubs and fastening elements onto the coolant tank.

The two heat exchangers 2, 3 are connected to one another by means of a fastening and connecting element 4, while the coolant cooler 2, referred to below for short as the cooler 2, is connected to a module or assembly carrier 6 by means of a latching connection 5 which is not explained in any more detail.

Arrangements of heat exchangers in a motor vehicle are known as so-called cooling modules, that is to say as a pre-assembled structural unit, which is for example composed of a coolant cooler, a refrigerant condenser, a charge-air cooler and/or an oil cooler which are cooled at the secondary side by ambient air.

DE 601 00 953 T2 (EP 1 319 579 B1) has disclosed a front module for motor vehicles which comprises a frame-shaped assembly carrier which holds individual cooling components such as a coolant cooler and a condenser.

This creates tolerance compensation between the two heat exchangers, the coolant cooler and the condenser, which expand to different extents during operation.

A thermostat, the wax pellet of which registers the temperature of the coolant flowing around it, provides for the allocation of coolant flow, either through the coolant cooler or past it via a short-circuit line.

Condensers are components of a coolant circuit for an air conditioning system, the condenser in air conditioning systems for motor vehicles often being arranged and mounted in the front region of the engine cavity together with a coolant radiator.

Radiators for motor vehicles serve for cooling an internal combustion engine and are connected to a coolant circuit which consists essentially of a radiator forward flow or engine return flow, of a radiator return flow or engine forward flow with coolant pump and of a bypass with a thermostatic valve.
