Embodiment Construction

[0046] exist figure 1 An electric-motor radiator fan 2 of a motor vehicle, not shown in detail, is shown in section. The radiator fan 2 is equipped with a fan frame 4 ( figure 2 ), electric motor 6 ( image 3 ) is carried centrally in the cutout by means of an annular motor holder 8 (motor ring).

[0047] The motor holder 8 is held in the cutout by means of six struts 10 distributed around the circumference. The struts 10 are provided with reference numerals only by way of example in the figures. The motor holder 8 and the strut 10 as well as the fan frame 4 are preferably embodied in one piece, ie in one piece or in one piece, for example as a common injection molded part.

[0048] Electric motor 6 (for example in image 3 ) is mechanically firmly engaged on the motor holder 8 by means of three peripherally distributed fastening screws 12 . As a heat or temperature insulation of the electric motor 6 , a cover-shaped or hood-shaped heat insulating plate 14 is provided a...

Abstract

The invention relates to an electric motor radiator fan (2) of a motor vehicle, comprising a fan frame (4) having a motor holder (8), an electric motor (6) which is inserted into the motor holder (8), and a heat shield (14) which is arranged on the end face of the electric motor (6), the heat shield (14) being seated on a projection (28) of the motor holder (8) by means of a recess (22), and the heat shield (14) being arranged on the end face of the electric motor (6). According to the invention, the heat shield (14) is pivoted about a projection (28) as an axis of rotation such that the heat shield (14) is screwed into at least one retaining contour (32) of the motor holder (8) in a form-fitting and / or force-fitting manner at least in sections.

Description

technical field [0001] The invention relates to an electric-motor radiator fan for a motor vehicle, having a fan frame with a motor holder, an electric motor inserted in the motor holder, and a heat shield arranged on the end side of the electric motor. The invention also relates to a heat shield for such a radiator fan. Background technique [0002] Motor vehicles with internal combustion engines generate a lot of heat during operation. To maintain the operating temperature or operating temperature within the air conditioning system, a coolant is typically used, which in turn must be cooled. This is usually accomplished by passing cooling air over cooling fins that exchange heat with the coolant. Since the driving wind, especially at low vehicle speeds, is usually not sufficient for cooling, it is possible, for example, to fasten a radiator fan with a radiator frame and an electric (electric motor) drive on the radiator with cooling fins, The radiator fan generates addit...
