Abstract
The object of the invention is a battery-operated welding and/or cutting device including a frame and at least one battery cell. The frame includes a cooling profile having an outer surface, which is in direct contact with the air surrounding the device. The cooling profile is provided to accommodate at least one battery cell, such that the cooling profile at least partly surrounds the battery cell in order to conduct heat from the battery cell to the cooling profile and, via the outer surface of the cooling profile, away from the device. The object of the invention is also a cooling profile.
Claims23
A battery-operated welding device, which device comprises a frame and at least two battery cells, wherein the frame comprises:
- a cooling profile having an outer surface, which is in direct connection with the air surrounding the device,
- wherein the cooling profile is provided to accommodate at least two battery cells such that the cooling profile at least partly surrounds each of the at least two batter cells in order to conduct heat out of the at least two battery cells into the cooling profile and, via the outer surface of the cooling profile, out of the device, and
- wherein distance from the at least two battery cells to the cooling profile is equal;
- the welding device further comprises a control and display element, which is provided at the outer surface of the cooling profile.
A cooling profile, having an outer surface, wherein the cooling profile is provided to accommodate at least two battery cells such, that the cooling profile at least partly surrounds each of the at least two battery cells, and that the at least two battery cells are directly, or via a solid medium, in contact with the cooling profile such, that heat is conducted from the at least two battery cells to the cooling profile and via the outer surface of the cooling profile out of the cooling profile, and which cooling profile is provided in a welding device such, that the outer surface of the cooling profile is part of the outer surface of the welding device,
- wherein a distance from the at least two battery cells to the cooling profile is equal, and
- wherein a control and display element is provided at the outer surface of the cooling profile.
