Definitions
- the invention relates to an electric air heating device in particular for a motor vehicle with electric Heating elements for heating the air and a housing, the one ground connection, an electrical supply connection and an electronic circuit for controlling the Supplying the heating elements and on which the heating elements in electrical contact with the ground terminal and the electrical supply connection are arranged
- a device of this kind is e.g. from the WO 02/057100 known.
- Such an electric air heating device in the electrical heating elements formed from PTC heating rods are, is known per se.
- the housing consists of a plastic material, in which the heating elements via a potting compound in an electrical contact via the electronic circuit with the electrical supply connection on the one hand and via a ground plate and one in electrical connection standing ground bolt with the ground connection on the other hand are connected.
- the thermal and the mechanical connection between the housing, the electronic circuit and the heating elements by means realized several components, where it is necessary for high tolerance compensation with additional fillers such as To provide adhesives and sealing compounds.
- the adhesives and the sealing compounds take over the actual Abdichtfunktion also the task, occurring forces and Record moments of the heating device. It is, however the seal and connection between the housing Made of plastic and the heating elements, usually made of Alumium mecanicstäben are formed, not easily processable and process-reliable. The required life can not be guaranteed so far.
- the forces occurring proportionately passed through to the contact of the circuit board, on which the electronic circuit is provided This passage can lead to mechanical loads the circuit board come with a high risk of damage the electronic components is connected.
- the object underlying the invention is in contrast, therein, an electric air heating device of the type mentioned above, with a lower Number of components, especially in the area of their Housing gets by.
- the housing made of an electrically conductive material exists and formed in one piece with the ground terminal is, the ground potential is due to the housing, so this not only the housing function but also the function of the in the known heating device existing ground plate, of ground bolt and ground connection for the customer Adaptation fulfilled.
- Ground plate, the ground bolt and the potting compounds, at the known heating device provided as separate components are, in the heating device according to the invention omitted.
- Heating device have the particular advantage that the heat conduction and heat dissipation from the electronic circuit and the circuit breaker supporting Circuit board in the heating area is possible that a heat exchange without loss of area due to proportional heat transfer possible through housing breakthroughs with weight optimization is, and that the mechanical fastening of all components, the attachment of the circuit board, the entire grounding the heating device, and the direct ground contact protected against reverse polarity via the molded on the housing Ground connection can be made for a customer-side cable.
- Manufacturing technology results in the advantages that due to the smaller number of components the number the production steps in series production is smaller and that processable processes can be used.
- the mechanical heat transfer interfaces for the heat energy removal from the circuit breakers in the heating areas easier and becomes the heat the circuit breaker directly across the housing into the actual Heated area dissipated, while the ground contact with reverse polarity protection via the ground connection and the absorption of forces and moments from the heating area are possible without additional components provided are.
- a electric air heating device in particular for a Motor vehicle consists essentially of electrical heating elements 3, on the one hand to an abutment 4 and on the other are arranged on a housing 1, of a Housing cover 2 is closed.
- Fig. 2 As shown in detail in Fig. 2, exist the heating elements 3 of heating rods 3b, with PTC components are filled. As shown in Fig. 6 are located 3b in the rods 3b reeds 3c, wherein the rods 3b one-sided represent the external connection. On the bars 3b Lamella 3a are mounted, which in the case of an electric Supply of the rods 3b resulting heat to the ambient air submit. The counter-bearing 4 is on the heating elements. 3 mounted and on the outer terminal side of the heating elements. 3 sealing elements 6 are inserted for sealing, through which the contact tongues 3c survive. The heating elements 3 are on the housing 1 pressed.
- the housing 1 consists of an electrically conductive Material, in particular of aluminum, and is in the in FIG. 6 manner in one piece with molded ground terminal 1a formed in the form of a mass dome.
- the heating elements 3b are about the housing 1 and the Massedom 1a with the ground connection 1b in conjunction, according to customer requirements can be executed, and are with their contact tongues 3c via a printed circuit board 7a equipped with circuit breakers 7a connected to the electrical supply connection that the electronic circuit for controlling the electrical supply the heating elements 3 carries.
- the ground connection 1b shown in the drawing Massedom 1a of the housing 1 is in the form of a screw-in However, he can also as an insert or Einpressteil be designed or constructive integrated or in a hole in Massedom 1a by means of a Be fixed screw.
- Embodiment of the heating device according to the invention are missing in the first embodiment provided Sealing elements 6 and are the heating elements 3b instead via a welded joint 9 with or without additives the housing 1 welded.
- the corresponding weld, formed after the mounting of the housing 1 on the rods 3a can be, to the inside or outside of the case 1, wherein a welding of both Positions is also possible, as shown in Figs. 9 and 11 is shown.
- a formed from a plastic material Gesimousedekkel 2 completes the basic structure.
- Cooling fins 1c provided in one piece with the housing 1 are formed.
- one-piece Housing 1 made of an electrically conductive material, especially made of aluminum, assumes the functions of a Housing, namely the protection of electronic circuits, the provision of a flange to the air box and the mechanically stable reception of the bars 3b, a ground plate, the recording of the circuit board, the discharge of the Circuit breakers 7a developed heating energy to the heating elements 3, the mechanically stable reception of the rods 3b, the grounding of the circuit board 7 and the heating elements 3 and a mass dome, namely the ground contact the circuit board 7, the heating elements 3 and the ground terminal 3b with possible reverse polarity protection to the positive connection in the form of a single component.
- both housing parts namely the housing cover 2 and the housing body 10 of a Made of plastic material and are separately a ground stud 12, a ground plate 11 and a potting compound 13 are provided, taken over the heating elements 3b in the housing 10 are.
- the housing 1 is in the heating device according to the invention but not only the transported heat energy to the Schuelementober Design from, proportionately, the heat energy through the integrated housing ribs 1c also directly supplied to the ambient air.
- a possible release of mechanical clamping connections, which are provided in the known heating device, at occurring temperature changes is by the one-piece Training of the housing 1 prevents, in which the rods 3b are pressed to the ground connection 1b.
- the earth connection 1b can be used for reverse polarity protection both connections as self-tapping screw, via a standard threaded connection or integrated each be designed according to customer requirements. Stress by moments, in the later assembly and use of the ground connection cable occur are disconnected from the circuit board 7.
- the ground contact of the rods 3b of the heating elements. 3 to the ground connection 1b is thus directly over the housing 1a, interfaces between a ground plate connected to the Heating rods is clamped, to ground plate and between the am Ground plate fastened ground bolt omitted.
- the seal is made by the form-fitting by the before Pressing the rods (3b) mounted sealing elements (6) or through the circumferential weld.
- sealants such as a silicone bead and potting compounds omitted and unnecessary
