Problems solved by technology

However, these gaps are not sufficient to reduce these conduction phenomena and there is still a risk of degradation of surrounding electronic components, especially when one wishes to seek high power heating modules or when at least one MOSFET is damaged

Embodiment Construction

[0046] figure 1 Shown is an additive heating device 1 according to the invention, which is intended to equip a motor vehicle. Such a heating device 1 is used in particular for the first few minutes of use of the motor vehicle, when the engine is not hot enough to ensure a supply of warm air into the vehicle interior.

[0047] The device 1 comprises a parallelepiped support frame 2 on which are mounted parallel heating modules 3 arranged to be passed by a flow of air to be heated. Using the control module 4 ( figure 2 and 5 ) or a driver to control the heating module 3 , said control module 4 or starter is mounted in a housing 5 fixed to the support frame 2 .

[0048] Each heating module 3 includes two electrodes or terminals, in Figure 7The middle marks are + and -, and a positive temperature coefficient (PTC) type resistance element 6 is arranged between the electrodes or terminals ( Figure 7 ). Two opposing heat sinks 8 are fixed to the electrodes in order to increa...

Abstract

The invention relates to a control module (4) for an electrical device (3), comprising: a printed circuit board (11) on which are mounted electrical and electronic components (12); and electronic power components (10) , the electronic power components are separated from the printed circuit board (11) and are held relative to the printed circuit board by at least one electrical connection body (18a, 18b, 18c) fixed to the printed circuit board (11) and Connected to one (D) of the terminals (S, D, G) of the electronic power part (10).

Description

technical field [0001] The invention relates to a control module for an electrical appliance, to a heating device comprising such a control module, in particular for a motor vehicle, and to a method for producing such a module. [0002] The invention applies in particular to the technical field of additive electric heating devices. Such heating devices are used in particular during the first few minutes of motor vehicle start-up, when the engine is not hot enough to ensure the supply of warm air into the vehicle interior. For diesel engines, this warm-up time is, for example, a period of 15 to 20 minutes. Background technique [0003] Such additive heating devices generally comprise a support frame on which parallel heating modules are mounted, which are arranged to be passed by the air flow to be heated. [0004] Each heating module comprises two electrodes between which a resistance element of the positive temperature coefficient type is arranged. Two opposing heat sink...
