International Publication No. 2004 / 027232A1 Swedish Patent Application No. 1050162-5

  The object of the present invention is to propose a further development of a module system of the above type in order to achieve a module system having a configuration that provides advantages in at least some aspects compared to the above type It is.

  According to the invention, said object is achieved with a modular system having the features defined in claim 1.

  The module system according to the invention is intended to form a radiator device for an automobile and comprises a basic module and two or more auxiliary modules connectable to the basic module.

The basic module of the module system according to the present invention is:
A main inlet intended to be connected to the automobile pipeline for feeding the circulating refrigerant to the radiator device formed by the module system;
A main outlet intended to be connected to the automobile pipeline for discharging the refrigerant from the radiator device;
An inlet tank connected to the main inlet;
An outlet tank connected to the main outlet;
A radiator element extending between an inlet tank and an outlet tank of the basic module so that the refrigerant flows through it from the basic module inlet tank to the basic module outlet tank while releasing heat to the surroundings. A radiator element provided with an intended through-flow duct.

Each auxiliary module of the module system according to the invention is
An inlet tank equipped with an inlet;
An outlet tank equipped with an outlet;
A radiator element extending between the inlet and outlet tanks of the auxiliary module so that the refrigerant flows through it from the auxiliary module inlet tank to the auxiliary module outlet tank while releasing heat to the surroundings. A radiator element provided with an intended through-flow duct.

  The inlet tank of the basic module is equipped with a first connection outlet at the upper end and a second connection outlet at the lower end, each of which can be connected to the inlet of the inlet tank of the respective auxiliary module . The outlet tank of the basic module is likewise provided with a first connection inlet at the upper end and a second connection inlet at the lower end, each of which is connected to the outlet of the outlet tank of the respective auxiliary module Is possible.

  By providing the basic module with its own radiator element, the basic module can be connected independently, i.e., the auxiliary module is completely connected to the basic module as a radiator device when a radiator device having only a small cooling capacity is required. It becomes possible to use it. In such a case, the connection outlet and connection inlet of the basic module are closed by suitable closing means such as lids, plugs, etc. The inlet and outlet tanks of the basic module are equipped with connecting outlets and connecting inlets respectively in both the upper and lower parts, thereby providing one or more auxiliary modules in the desired direction or a plurality of opposing vertical auxiliary modules. It can also be added to the basic module. As a result, in each automobile, there is a greater degree of freedom for adapting the radiator device to the space available for it.

  The module system according to the invention does not require any additional pipelines between the various modules to connect them together in order to achieve a radiator device with a cooling capacity depending on the cooling needs. Without having to connect one or more auxiliary modules directly to the basic module. Thereby, a leak-free coupling of the modules is easily achieved.

  According to an embodiment of the present invention, the module system comprises two or more auxiliary modules having different heights. By using different heights of auxiliary modules, it is possible to achieve a relatively large number of different sized radiator devices using a limited number of auxiliary modules. For example, a basic module and two auxiliary modules of different heights can be used to form a radiator device of four different dimensions, but using a basic module and two auxiliary modules of the same height, Only radiator devices of different dimensions can be formed.

  According to another embodiment of the present invention, the one or more auxiliary modules have valve means arranged close to the inlet of the auxiliary module inlet tank or close to the outlet of the auxiliary module outlet tank. The valve means is switchable between a closed state and an open state, in which the valve means is adapted to hold the respective inlet or outlet in the closed state, thereby The refrigerant is prevented from passing, and in the open state, the valve means is adapted to hold the respective inlet or outlet open so that the refrigerant can pass. Closing the valve means of the auxiliary module is an easy and quick measure depending on any need to stop the refrigerant flowing through the auxiliary module that is part of the radiator device formed by the module system according to the invention. . When the refrigerant is thus guided through a reduced portion of the radiator elements that make up the radiator device, compared to when all the radiator elements of the radiator device are effective with respect to the refrigerant flowing through, The refrigerant has a higher flow rate through the effective radiator element at that time. Therefore, the residence time of the refrigerant in the radiator device is shortened, and the cooling effect of the refrigerant is reduced. In the case of a charge air cooler, there is a risk of forming ice in the through-flow duct of the radiator element. In the charge air cooler formed by the module system according to the invention, the valve means of the auxiliary module is used to reduce the cooling capacity of the charge air cooler, thereby freezing in the through-flow duct of the radiator element. Risk can be reduced.

  Other advantageous features of the module system according to the invention are indicated by the independent claims and the description given below.

  The invention also relates to a charge air cooler having the characteristics defined in claim 11 and a radiator liquid cooler having the characteristics defined in claim 12.
