Definitions

  • the present invention relates to an electric heater with PTC elements, particularly for motor vehicle cabin ventilation systems.
  • PTC elements Electric heaters with PTC thermistors, commonly termed PTC elements, are known and are used to heat the air that is circulated within the cabin of motor vehicles.
  • These heaters generally comprise a frame that supports and holds together a plurality of radiating elements, which are usually arranged side by side and superimposed and between which the PTC elements are interposed.
  • the PTC elements are generally formed in the shape of plates or pads and have the property of warming when they are supplied with electric power by means of electrical contacts applied to their two opposite faces. PTC elements inherently have an electrical resistance that increases as the temperature increases and therefore are unable to become hotter than a given temperature. Because of this property, PTC elements are used in all applications in which one wishes to avoid dangers of overheating or fire with absolute safety. Use in motor vehicles is a typical application of PTC elements, in view of the high safety required against the danger of fire.
  • the radiating elements which are heated by conduction by the PTC elements, are designed to provide the heat generated by the PTC elements with a large heat exchange surface so as to achieve rapid heating of the air that strikes them.
  • the radiating elements are generally made of a metal that has excellent thermal conductivity and are usually shaped like a contoured and/or folded lamina in order to offer a large heat exchange surface despite a small overall space occupation.
  • the radiating elements are constituted by folded laminas interposed between conducting plates that provide electrical and thermal contact with the PTC elements.
  • the radiating elements are further used very often to connect the PTC elements to the electrical power supply connectors.
  • the radiating elements with their folded-lamina structure, are rather complicated to assemble and significantly increase the overall production costs of the heater.
  • the region of contact between the radiating elements and the conducting plates or the PTC elements is limited, leading to reduced efficiency in the transmission of heat from the PTC elements to the radiating elements.
  • the folding of the radiating elements, as well as the regions of contact between the radiating elements and the conducting plates, can cause the retention of dust or dirt, which may induce leakage of current on the surface of the containment frames of the PTC elements.
  • the aim of the present invention is to solve the problems cited above by providing an electric heater with PTC elements, particularly for motor vehicle cabin ventilation systems, that ensures high efficiency in transmitting the generated heat.
  • an object of the invention is to provide an electric heater with PTC elements that is compact, mechanically strong and simple to assemble.
  • Another object of the invention is to provide an electric heater with PTC elements that is highly reliable in operation and offers adequate assurances of safety.
  • Another object of the invention is to provide an electric heater with PTC elements that can be manufactured at competitive costs.
  • an electric heater with PTC elements particularly for motor vehicle cabin ventilation systems, comprising at least one radiating element and at least one PTC element that can be supplied with electric power and is adapted to transmit heat to the radiating element, characterized in that said radiating element comprises an extruded body that has a plurality of fins in order to increase its heat exchange surface.
  • the heater according to the invention comprises at least one radiating element 2 and at least one PTC element 3 that can be supplied with electric power and is arranged so as to transmit heat to the radiating element 2.

  • the radiating element 2 is shaped like an elongated bar, with a substantially rectangular transverse cross-section that is delimited on two opposite longitudinal sides by two side walls 5 and 6 that face each other and are connected by a plurality of fins 4.
  • Said fins 4 are formed by a plurality of holes 7 of the extruded body of the radiating element 2, which are arranged side by side sequentially along the longitudinal extension of the extruded body of the radiating element 2.
  • the extrusion of the body of the radiating element 2 occurs along a direction that is perpendicular to the longitudinal extension of the radiating element 2 in its final configuration.
  • a bar in which a plurality of holes 7 are formed internally is extruded continuously and said bar is then cut transversely in order to obtain the extruded body of the radiating element 2.
  • the radiating element 2 is constituted by two extruded bodies, respectively a first body 8 and a second body 9, which are aligned and coupled, by way of an interlocking coupling 10, at one of their longitudinal ends.
  • the two outer faces of the side walls 5 and 6, on which the PTC elements 3 are meant to be rested are substantially flat.
  • Each PTC element 3 is constituted in a per se known manner by a plate-like body that rests, with one of its two larger faces, against one of the outer faces of the side walls 5 or 6 of the radiating element 2.
  • the heater 1 preferably comprises a plurality of radiating elements 2, stacked so that the outer faces of the side walls 5 and 6 of the various radiating elements 2 face each other and so that multiple PTC elements 3 are interposed.
  • the illustrated embodiment there are seven radiating elements 2 with two PTC elements 3 interposed for every two contiguous radiating elements of the stack of radiating elements.
  • the illustrated heater there are seven radiating elements 2 and ten PTC elements 3.
  • the PTC elements 3 are arranged in an intermediate region of the extension of each body 8 and 9 that composes a radiating element 2.
  • the radiating elements 2 are in direct contact with the PTC elements 3 and are electrically connected to them so as to allow the supply of electric power to the PTC elements 3 through said radiating elements 2, as will become better apparent hereinafter.
  • said positioning means comprise a positioning seat 11 that is formed on the outer face of the side wall 5 of the radiating elements 2 and is adapted to accommodate partially at least one PTC element 3.
  • the positioning seat 11 can be obtained by machining in a protrusion that can be provided during the extrusion of the bodies 8 and 9 on the outer face of the side wall 5.
  • the positioning means can also be constituted by a positioning bracket 12, which is interposed between two contiguous radiating elements 2 in the stacked arrangement and forms at least one positioning seat 13 that is adapted to accommodate partially a PTC element 3.

  • the positioning of the PTC elements 3, in the variation shown in Figure 3 can be completed by means of shoulders formed by protrusions 15 provided for this purpose on the outer face of the side wall 5.
  • the heater according to the invention comprises a supporting frame for containing and supporting the plurality of radiating elements 2 and of PTC elements 3.
  • Said supporting frame is substantially composed of two longitudinal side walls 21 and 22 that respectively face the outer face of the side wall 5 of the radiating element 2 located at the top of the stack of radiating elements 2 and, in a downward region, the outer face of the side wall 6 of the radiating element 2 located at the lower end of the stack of radiating elements 2.
  • the longitudinal side walls 21 and 22 of the frame are connected by two heads 23 and 24 that partially contain the longitudinal ends of the radiating elements 2.
  • presser means are provided that act on the stack of radiating elements 2 in order to reinforce the contact of the radiating elements 2 with the PTC elements 3.
  • Said presser means comprise elastic means, which are preloaded during the assembly of the heater according to the invention.
  • said presser means comprise at least one, but preferably two, leaf springs 25 and 26 that are interposed between the side wall 21 of the frame and the side wall 5 of the radiating element 2 located at the top of the stack of radiating elements 2.
  • Two leaf springs 25 and 26 can be provided, in a similar manner, also between the side wall 22 of the frame and the outer face of the side wall 6 of the radiating element 2 located at the lower end of the stack of radiating elements 2.
  • the leaf springs 25 and 26 are arranged so as to apply maximum compression at the region of the radiating elements 2 that is affected by the PTC elements 3.
  • the blocks 27 and 28 are preferably arranged in alignment with the regions of the radiating elements 2 that make contact with the PTC elements 3.
  • a strap 30 also for the embodiments shown in Figures 1 and 6, said strap connecting one another the side walls 21 and 22 of the frame at an intermediate region of their longitudinal extension.
  • the heads 23 and 24 are used conveniently to accommodate the electrical connections for feeding the PTC elements 3.
  • the head 23 supports electrical power supply connectors 35 of the quick-coupling type, for example of the type commonly known as Faston, which are connected electrically to some of the radiating elements 2, and an electrical power supply connector 36 of a similar kind, which is connected electrically to the other radiating elements 2.
  • electrical power supply connectors 35 of the quick-coupling type for example of the type commonly known as Faston, which are connected electrically to some of the radiating elements 2, and an electrical power supply connector 36 of a similar kind, which is connected electrically to the other radiating elements 2.
  • the connector 36 is connected electrically to the radiating element 2 located at the top of the stack of radiating elements 2 and the radiating elements 2 that are arranged below said top radiating element are connected alternately to one of the connectors 35 or to the radiating element 2 that constitutes the top of the stack.
  • the electrical connection between the radiating element 2 located at the top of the stack and the other radiating elements is provided by way of electrical connection elements that are accommodated within the head 24.
