Cooling arrangement (1) according to one of the preceding claims, characterized in that the cooling element (10) has a number of cooling fins (15) which project from a contact surface (16), wherein the Peltier elements (5) are in contact with the contact surface (16) with their second side (7).
  9. Cooling arrangement (1) according to one of the preceding claims, characterized in that the at least one Peltier element (5) or that the Peltier elements (5) are arranged electrically insulated but thermally conductive between the at least one busbar (2, 3) and the cooling element (10).
  10. Arrangement of a cooling arrangement (1) for cooling a vehicle battery, a battery cell module and/or a charging socket (17), in particular an electrically powered motor vehicle, wherein at least one busbar (2, 3) is provided, preferably two busbars (2, 3) which can be cooled by means of a cooling arrangement (1) according to one of the preceding claims.

Description

The invention relates to a cooling arrangement, in particular for a vehicle battery, for a battery cell module and/or for a charging socket, in particular of an electrically powered motor vehicle. Electrically powered vehicles have a vehicle battery, at least a battery cell module, and/or a charging socket, all involved in charging or discharging the battery. This process can generate high temperatures on relevant components, which should be avoided. This problem is quite well known. DE 10 2013 218 674 A1 One proposed solution involves cooling a battery cell within its housing by integrating a Peltier element into the housing in such a way that part of the element is located inside the housing and another part outside. However, such an arrangement is not always feasible and is also expensive, as the Peltier elements would have to be integrated into each individual battery cell, and the necessary space is not always available. The task is to create a cooling arrangement that is simple and effective, even when installation space is limited. Another task is to implement such a cooling arrangement in a suitable, improved configuration. The problem with the cooling arrangement is solved by the features of claim 1. One embodiment of the invention relates to a cooling arrangement with at least one busbar or with two busbars, which are used in particular as electrical supply lines in an electrically powered motor vehicle, wherein the at least one busbar has a substantially flat contact area on which at least one Peltier element is arranged, wherein the respective Peltier element has a first side and an opposing second side and two electrical supply lines to the Peltier element, the first side being arranged in contact with the busbar, and wherein a cooling element is provided which is arranged such that the second side of the Peltier element is in contact with the cooling element. This allows for a very general arrangement that cools busbars, for example, to cool a vehicle battery, a battery cell module, and/or a charging socket, if desired. Cooling via the busbars allows for a very compact and space-saving design. In an advantageous embodiment, it is expedient to arrange at least one Peltier element on each busbar, positioned such that the first side of the respective Peltier element is in contact with one of the busbars, while the second side of the respective Peltier element is in contact with the cooling element. This improves the cooling efficiency. It is also advantageous to arrange multiple Peltier elements on a busbar, positioned such that the first side of each Peltier element is in contact with the busbar, while the second side of each Peltier element is in contact with the cooling element. This also improves the cooling efficiency. It is also advantageous if a plurality of Peltier elements are arranged on each of the busbars, positioned such that the first side of each Peltier element is in contact with one of the busbars, while the second side of each Peltier element is in contact with the cooling element. This also improves the cooling efficiency. It is also advantageous if the Peltier elements are arranged in a row along one of the busbars. This results in a space-saving and effectively cooling design. It is particularly advantageous if the Peltier elements are arranged in such a way that, when current flows through them, they cool at least one busbar(s) and transfer heat from the busbar(s) to the cooling element. This also improves the cooling efficiency. In one embodiment, it is also advantageous if the cooling element is designed as at least one heat sink, which dissipates heat by transferring heat to a medium flowing towards the cooling element. This allows for efficient and space-saving heat dissipation. It is also advantageous if the cooling element has a number of cooling fins that protrude from a contact surface, with the Peltier elements having their second side in contact with the contact surface. are in contact. This design further improved heat dissipation. This allows heat to be released effectively and in a space-saving manner. It is also advantageous if at least one Peltier element, or the Peltier elements, are electrically insulated but thermally conductive and arranged between at least one busbar and the cooling element. This allows the cooling element to be kept at a neutral potential without posing a hazard. The problem with the arrangement is solved by the features of claim 10. One embodiment of the invention relates to an arrangement of a cooling arrangement for cooling a vehicle battery, a battery cell module and/or a charging socket, in particular an electrically powered motor vehicle, wherein at least one busbar is provided, preferably two busbars, which can be cooled by means of a cooling arrangement. The invention will now be explained in detail using exemplary embodiments and with reference to the drawings. The drawings show: 1 a schematic view of a cooling arrangement accor
