Abstract
A temperature control device is provided for the temperature control of a battery. The temperature control device has an upper part with an upper side and an underside, which has on the upper side a thermal interface to the battery. Furthermore, the temperature control device has at least one lower part, which has an embossed structure in order to embody a sealing edge and to embody a cavity for guiding temperature control fluid. The sealing edge is arranged on an upper side of the lower part, and is connectable to the underside of the upper part in a fluid-tight manner.
Claims22
A temperature control device for a temperature control of a battery, the temperature control device comprising:
- an upper plate with an upper side as a thermal interface to the battery and to an underside;
- at least one lower plate, which has an embossed structure in order to embody a sealing edge and to embody a cavity for guiding temperature control fluid, the upper plate being overlaid over and connected to the lower plate such that the upper plate and the lower plate form a housing with the cavity therebetween;
- at least one passage disposed between the upper plate and the lower plate, the at least one passage providing entry into the cavity of the housing;
- and
- at least one flat tube inserted into the cavity via the at least one passage and configured to guide the temperature control fluid,
- wherein the sealing edge is arranged on an upper side of the lower plate, and is soldered to the underside of the upper plate in a fluid-tight manner,
- wherein a first portion of the at least one flat tube extends into the cavity and a second portion of the at least one flat tube extends to an outside of the at least one passage, such that the second portion of the at least one flat tube is positioned outside of the housing, and
- wherein the at least one flat tube is discrete from the upper plate, the at least one lower plate, the cavity and the at least one passage.

A device, comprising:
- an upper plate;
- a lower plate, the lower plate comprising an embossed structure defining a cavity for guiding a fluid, the upper plate being overlaid over and connected to the lower plate such that the upper plate and the lower plate form a housing with the cavity therebetween;
- a sealing edge arranged on an upper side of the lower plate and connected to an underside of the upper plate in a fluid-tight manner;
- a flat tube, for guiding the fluid, connected to the underside of the upper plate;
- and
- a passage disposed between the upper plate and the lower plate and interrupting the sealing edge, such that the passage provides entry into the cavity,
- wherein a first portion of the flat tube extends into the cavity via the passage and a second portion of the flat tube extends to an outside of the passage, such that the second portion of the flat tube is positioned outside of the housing, and
- wherein the flat tube is discrete from the upper plate, the lower plate the cavity and the passage.
