THERMAL MANAGEMENT IN THE FIELD OF E-MOBILITY

Abstract

The invention relates to a ceramic cooling and heating body for controlling the temperature of components, wherein the cooling and heating body consists of a plate-shaped support with a front side, an opposite rear side and side faces connecting the front side to the rear side, and metallizations, connected to the support, are arranged on the front side and/or the rear side, and the support has cooling elements. In order to be able to control the temperature of any electrical or electronic component, it is proposed according to the invention that a heating structure is affixed to the front side and/or the rear side.

Claims

2. The heating and cooling body according to claim 1, wherein the heating structure has two terminal poles and both terminal poles are continued to the edge of the front side and/or the rear side, where the heating structure is located, and continue from there around the edge between the front side and the side face and a metallized terminal point on the side face opens into each.

3. The heating and cooling body according to claim 1, wherein the heating structure covers the entire front side and/or rear side in a meandering pattern.

4. The heating and cooling body according to claim 1, wherein the cooling elements are internal cooling channels having at least one inlet opening and at least one outlet opening in the support, or they are external cooling ribs, which are designed in one piece with the support.

5. The heating and cooling body according to claim 4, wherein the cooling channels are arranged parallel to one another, wherein all the inlet openings are arranged on one side face and all the outlet openings are arranged on the opposite side face of the heating and cooling body.

6. The heating and cooling body according to claim 1, wherein the metallized areas are sintered to the support.

7. The heating and cooling body according to claim 1, wherein the components are electric or electronic power components, whose terminal poles are connected to the metallized areas.

8. The heating and cooling body according to claim 1, wherein several heating and cooling bodies having internal cooling channels are arranged parallel to one another, and the inlet openings and the outlet openings of the heating and cooling bodies are connected to central inlet and outlet lines for the cooling medium.

9. The heating and cooling body according to claim 8, wherein the components are arranged between the heating and cooling bodies and are connected to them in a heat conducting manner.

10. The heating and cooling body according to claim 1, wherein the components are batteries, in particular lithium ion batteries.

11. A use of a heating and cooling body according to claim 1 in vehicles having electric drive.

Description

EXAMPLE

[0027] FIGS. 1, 2 and 3 show several views of a plate-shaped heating and cooling body 1 made of a ceramic. FIG. 1 shows the front side 2 and two side faces 3a, 3b of the heating and cooling body 1. FIG. 2 shows a view of the side face 3b, and FIG. 3 shows the front side 2 of the heating and cooling body 1.

[0028] The heating and cooling body 1 consists of a front side 2 and a rear side (not shown), wherein the front side 2 is connected to the rear side by means of side faces 3. The heating and cooling body 1 is provided with a heating structure 4 on its front side 2. In the specific embodiment shown here, the heating structure 4, which is designed in a meandering shape, covers the entire front side 2. Both terminal poles 5, 6 of the heating structure 4 are continued to the edge of the front side 2 of the heating and cooling body 1 and are guided around the edge 7, each opening into a metallized connecting site 8 on the side face 3a.

[0029] For cooling the heating and cooling body 1, it has internal cooling channels 9 through which a cooling liquid is pumped. In the specific embodiment shown here, these cooling channels 9 are arranged parallel to one another, wherein all the inlet openings 10 are arranged on the side face 3b and all the outlet openings are arranged on the opposite side face of the heating and cooling body 1.

[0030] This heating and cooling body 1 is connected to the battery cells 11 (see FIG. 4) of the lithium ion battery in such a way that good dissipation of heat and good input of heat are ensured so a good thermal contact is established.

[0031] The heating and cooling body 1 shown here may have metallization on the rear side opposite the heating structure 4 and components to be cooled may be soldered there.

[0032] The cooling by means of the cooling channels 9 can be replaced or enhanced by fins on the rear side of the heating and cooling body. In this case the fins would be cooled by a gas, for example, air.

[0033] FIG. 4 shows battery cells 11 of a lithium ion battery arranged between two heating and cooling bodies 1. These heating and cooling bodies 1 are identical to those of FIGS. 1 to 3. The battery cells 11 may be connected to the heating and cooling bodies 1 with a good heat conducting paste. In order to be able to pump cooling fluid through the internal cooling channels 9 (see FIGS. 1 to 3) of the heating and cooling body 1, the internal cooling channels 9 are connected to external cooling lines 13. There is a bottom cooling channel 14 and two side cooling channels 15, each having an inlet and at least one outlet. The heating structures 4 on the heating and cooling bodies 1 are connected to at least one electric power source (not shown) by means of electric connecting lines 16.
