Abstract:
The invention relates to a heating device of a motor vehicle comprising an internal combustion engine (2) and a vehicle interior. Said heating device encompasses a cooling circuit (1) for cooling the internal combustion engine (2), a heating circuit (6) that is provided with at least one heating element (7) and is used for heating the vehicle interior, and an additional electric heater, especially an auxiliary PTC heating unit (8). According to the invention, a heat source can be connected to the cooling circuit and/or the heating circuit (6) as a second supplementary heater (9).
Abstract:
A filter element may include a first end disc, a second end disc, a filter medium arranged between the first and second end discs, wherein the first and second end discs are spaced by a filter medium. A third end disc may connect the first and second end discs and be arranged obliquely to at least one of the first end disc and the second end disc. The third end disc may include at least one of an inlet and outlet.
Abstract:
A catch box may include two air intake sections of an air intake system, wherein the catch box is embodied as water separator at the same time.
Abstract:
A filter device is disclosed, comprising an air filter for a fresh air system of a motor vehicle. The filter device further comprises a filter housing which contains a receiving space. An annular filter element is inserted into the receiving space. The device also comprises a cover for closing the receiving space. The cover is detachably fastened to the filter housing by means of a bayonet catch, so that the cover can be inserted axially into a cover receptacle formed on the filter housing and, when inserted, can be rotated between an unlocking position and a locking position.
Abstract:
The invention relates to a heat exchanger, in particular for a stationary UT heating body (1) of a motor vehicle heater. According to the invention, said heat exchanger comprises a ventilation device which is embodied as a ventilation bore (22, 36) which is, in particular, embodied in the separating wall of the upper coolant tank (4) of the heating body and is located at a distance from the feed and return section (10).
Abstract:
The invention relates to a gas intake zone of a separable gas filter housing which removably accommodates a filter element. The gas intake zone is used as a prefilter and comprises a plurality of axially adjacent, axially impinged cyclone collectors that are provided with respective spin generators in the inlet zones thereof and gas-discharging immersion tubes at the discharge end within annular ducts which are located between the immersion tubes and the respectively associated outer cyclone walls while being used for pre-separating dirt particles separated in an outer radial direction in the individual cyclones by means of centrifugal forces, the immersion tubes being axially dipped into the interior of the cyclone collectors. The aim of the invention is to be able to efficiently produce the gas intake zone while especially making the same easy to clean. The aim is achieved by a prefilter which is characterized in that all cyclones are composed of a unit encompassing three areas, i.e. a first area that is monolithically molded into the filter housing and is fitted with first partial spin-generating elements, a second area that is embodied as an inserted part and is provided with second partial spin-generating elements which adjoin the first partial spin-generating elements in the direction of flow and form the spin generators along with the first partial spin-generating elements, and hollow cylindrical ducts located downstream from the spin generators, as well as a third area that is also embodied as an insertable part, contains the immersion tubes, and is equipped with a bottom which encloses the immersion tubes so as to form a dirt particle collection chamber within the filter housing, the dirt particle collection chamber bordering the annular ducts of the cyclones.
Abstract:
The invention relates to a heat exchanger provided for heating purposes, particularly for a motor vehicle, comprising: a number of parallel pipes, at least one electric heating device (4), which is mounted each time between two adjacent pipes, and comprising a number of fin elements (5) situated between each pair of adjacent pipes and between each heating device (4) and the pipes adjacent thereto. In order to be able to better control the power absorption of the heating devices (4), each heating device (4) comprises two separately controllable heating sections (6, 7). One heating section (6) is placed on one side (8) of the heating device (4) facing one adjacent pipe, whereas the other heating section (7) is placed on an opposite side (9) of the heating device (4) facing the other adjacent pipe.
Abstract:
A filter element may include a first end disc, a second end disc, a filter medium arranged between the first and second end discs, wherein the first and second end discs are spaced by a filter medium. A third end disc may connect the first and second end discs and be arranged obliquely to at least one of the first end disc and the second end disc. The third end disc may include at least one of an inlet and outlet,
Abstract:
A filter arrangement may include a housing having two front walls substantially extended on both sides of a housing center plane and a circumferential wall connecting the front walls. The housing may include an untreated space inlet and a clean space outlet. A filter insert may be arranged between the inlet and the outlet and include two bottom discs that are adjacent to the side walls in the assembled state of the filter insert. The filter insert may include a filter wall extending between and connecting the bottom discs. The filter wall may extend substantially orthogonal to the housing center plane. A lateral disc may define an opening configured to be tightly connected to at least one of the inlet and the outlet. The front walls may be coupled to the bottom discs in the assembled state of the filter insert through interacting profile parts arranged on at least one of the front walls and the bottom discs into a double wall.
