Embodiment Construction

[0018] As shown in the figure, the charge air / coolant cooler 1 as a heat exchanger between the charge air and the coolant has a plurality of coolant pans 2 stacked on top of each other. Here, two inflow holes 3 and two outflow holes 4 are respectively provided in each cooling liquid pan 2 , through which the cooling liquid as a heat exchange medium enters the gap in the middle of the cooling liquid pan 2 or flows out there. The direction of flow is indicated by arrows in the figure. After the coolant enters through the inflow hole 3, it spreads in the entire width of the gap in the middle of the coolant plate 2, and flows evenly to the outflow hole 4 (see Figure 3), so that the gap between the inflow hole 3 and the outflow hole 4 The entire length and width in between are flowed through, so that the heat transfer of the charge air to be cooled between the coolant pans 2 through the charge air / coolant cooler 1 can be optimized.

[0019] The holes 3 and 4 in the coolant tray 2 ...

Abstract

The invention relates to a heat exchanger, especially a charge-air/coolant cooler (1), consisting of a plurality of disks (2), two adjacent disks (2) defining an intermediate region through which a heat exchanging medium flows. Said heat exchanger also comprises a heat exchanging medium inlet (9) and a heat exchanging medium outlet (10), that are common to the disks (2). At least two heat exchanging medium channels (5, 6) are respectively provided for the heat exchanging medium inlet and the heat exchanging medium outlet (9 and 10).

Description

technical field [0001] The invention relates to a heat exchanger of disc construction, in particular a charge air / coolant cooler. Background technique [0002] In conventional plate-type charge air / coolant coolers, the charge air and coolant enter the coolant plate via a single connection. However, the cooling efficiency of this charge air / coolant radiator is not yet satisfactory. Contents of the invention [0003] It is an object of the present invention to provide an improved heat exchanger. [0004] This object is achieved by a heat exchanger having the following characteristics. Further features provide advantageous embodiments. [0005] According to the invention, a plate-shaped heat exchanger, in particular a charge air / coolant cooler, has a plurality of plates, wherein two adjacent plates define an intermediate space through which a heat-exchange medium flows ; It also has a heat exchange medium inlet and a heat exchange medium outlet shared by each plate, here,...
