摘要： A dehumidifying device for a housing, in particular an electronics housing of an electromotor with a dehumidifying chamber includes a wall inside of which a hygroscopic material is received which is designed to bind air moisture from the dehumidifying chamber. The wall of the dehumidifying chamber includes at least one inner membrane permeable to vapor which can be brought into an active connection with an inner receiving space of the housing and an outer membrane which can be brought into an active connection with the outside environment of the housing. The at least one inner membrane and the outer membrane are permeable to vapor at least in a direction in which a transport of air moisture out of the inner receiving space of the housing through the dehumidifying chamber into an outside environment can be ensured.

摘要： The present invention concerns an electronic housing for an electric motor, consisting of a housing holder part with a housing floor and a housing wall comprising the housing floor. A housing opening lies opposite the housing floor. Arranged in the housing holder part is a motor electronic component with an electronic printed circuit board, which is arranged parallel to the opening plane of the housing opening. Detachably arranged on the electronic printed circuit board or on the motor electronic component, on a side of the electronic printed circuit board facing away from the housing floor is a contact protecting component, which covers this surface, from an electrically insulating material, which has at least partially a grid structure as an air outlet.

摘要： A fan includes a sealed electronics housing, in which a printed circuit board having electronic components is arranged. The electronics housing is divided into an upper region and a lower region. A cooling wheel which is arranged in the lower region is axially adjacent to the printed circuit board. The printed circuit board has at least one central opening and a plurality of peripheral-edge openings or gaps in order to bring the upper region into fluid communication with the lower region. Air is drawn out of the upper region into the lower region by the cooling wheel via the at least one central opening and, via the plurality of peripheral-edge openings or gaps. The air is fed back into the upper region. An air circuit having at least one air flow develops along a surface of the printed circuit board on which the electronic components are arranged.
