Abstract: A temperature control device for arrangement on a surface to be tempered, having an upper part, a lower part, an electrical connection and at least one first tempering element in connection with the electrical connection. The lower part is designed for engagement with the upper part such that a surface pressure can be provided with the upper part and the lower part in the orthogonal direction to an upper side and a lower side of the first tempering element for surface coupling of the lower part to the surface to be tempered. The temperature control device can be fastened longitudinally displaceably to the surface to be tempered in such a way that a change in length of the temperature control device in the longitudinal direction of the temperature control device can be accommodated.

Abstract: The invention relates to a device for temperature control in potentially explosive areas, comprising a temperature controller (10) and a housing (11) in which the temperature controller (10) is arranged, the housing (11) having a sealed opening (12) through which electrical lines (13, 14) of the temperature controller (10) are passed. It is characterized in that the temperature controller (10) has a measuring surface (15) which lies directly against an inner wall (16) of the housing (11) at least in certain areas and is electrically connected to an earthing tab (17), said earthing tab (17) being electrically connected to another line (18) which is guided through the opening (12).

Abstract: The invention relates to a fan device with at least one locking element for securing the fan device to a wall portion, in particular to an electrical enclosure wall, with a front and a rear face. The fan device is inserted into a front-face wall portion opening in a pressureless manner, and the locking element is movable in the direction of the rear face of the wall portion in the inserted state.

Abstract: A temperature control device, in particular a resistance heating device, for arrangement on a surface to be tempered, having at least one upper part, a lower part, an electrical connection and at least one first tempering element, in particular a heating element, in connection with the electrical connection. The upper part is arranged opposite an upper side of the first tempering element and the lower part is arranged opposite an underside of the first tempering element. The lower part is designed for engagement with the upper part such that a surface pressure can be provided with the upper part and the lower part in the orthogonal direction to the upper side and the lower side of the first tempering element for surface coupling of the lower part to the surface to be tempered.

Abstract: A housing for an electrical device wherein at least a first part of a lower outer wall of the housing is recessed in relation to a second part of the lower outer wall of the housing to form a cooling channel on the lower side of the housing, and wherein a heat sink of the electrical device can be arranged in the housing adjoining the cooling channel such that heat emitted by the heat sink can be dissipated by the cooling channel.

Abstract: A cooling and holding device for heating-elements, more particularly PTC heating-elements, including a flat housing having at least one heating shaft in which there is at least one heating-element, wherein the heating shaft has opposing shaft walls between which the heating-element is clamped, and at least one side slit that separates the shaft walls such that the distance between the shaft walls can be varied for installation of the heating-element, wherein at least one clamping section outwardly protruding from the flat housing, grips the flat housing, spanning the side slit, and is elastically deformed in the mounted state of the heating-element so as to provide a pressing force of the shaft walls on the heating-element in the assembled state.
