Definitions
- the present invention relates to an application heater module for heating gases that are introduced through the intake duct of an automotive motor with electronic temperature control incorporated consisting of two fundamental parts: heating element ( resistance in the form of continuous tape), and power control circuit that measures a representative temperature of the heater module and manages the dissipation of electrical energy in the heating element.
- the heater module can be mounted in an intake manifold preferably of plastic without deterioration thereof due to excess temperature, and optimizing the performance of the engine, which is achieved through the measurement of any of the temperatures representative of the heating module and the interposition of the control electronics between the power supply and the heating element, such that the accidental or intentional connection of said heating element to the battery is prevented.
- heaters such as those described in the invention patents US 4 512 322, US 4 685 437, US 5 988 146, WO 00/34643 are used. These heaters consist of a metal frame such as aluminum, on which a resistance in the form of a tape isolated from it is mounted through ceramic insulators, not having any element that allows to know its temperature and implement any safety function that we allow said heater module to be mounted on a plastic manifold without risk of deterioration due to excess temperature.
- the heater module must meet the following requirements:
- the power dissipated in the resistance is:
- V being constant and equal to the battery voltage, so if we want to be able to supply high powers we need a low ohmic resistance.
- the intake gas heater module of an automotive engine with electronic temperature control incorporated by this invention satisfactorily solves the problem presented in each of the points described above, consisting of two fundamental parts: heating element (resistance in form of continuous tape), and power control circuit that measures a representative temperature of the heating module and manages the dissipation of electrical energy in the heating element, located or integrated in the same metal frame preferably of aluminum.
- heating element resistance in form of continuous tape
- power control circuit that measures a representative temperature of the heating module and manages the dissipation of electrical energy in the heating element, located or integrated in the same metal frame preferably of aluminum.
- the heating element is mounted insulated from the frame through the use of ceramic insulators on which it rests and expands freely to absorb its dilations preventing it from deforming.
- This heating element is electrically connected at one of its ends to the frame, from which it takes the mass, and on the other it is connected through a conductor to the power control circuit through which it takes the battery power.
- heating element we refer to a modular heating element in which the resistance Electric in the form of continuous tape can be single or several in parallel. That the heating element is constructed with a single or with several resistances will be determined by the maximum power that it is desired to dissipate in each given application (unit displacement of the engine, number of cylinders, etc.), and the power that is capable of managing each of the power switches in such a way that each switch controls a single resistor.
- the adhered power control circuit (located) on the frame itself consists of the following minimum components: power switches (as many as resistors the heating element has, each controls a resistor), control logic, temperature sensor / sensors and control connector through which it communicates with the Control Unit
- ECU Electronic
- all these components are mounted on a preferably ceramic substrate adhered with adhesive material or thermoconductive glue on the frame.
- This circuit allows a preferably modulated control of the power dissipated in the heating element.
- the amount of power dissipated and supplied to the intake air flow is determined at all times by the ECU and if at any time the temperature of the frame exceeds the maximum temperature of the intake manifold plastic, with which it is in contact, then automatically power is no longer supplied to the heating element.
- this heater module with a built-in power circuit is designed to be mounted on a plastic manifold, its incorporation into collectors of other conventional materials and mainly those composed or formed from materials of low working temperature.
- Knowledge of the temperature of the heater module frame is an essential requirement to implement a protection function that prevents the temperature of the module points that are in contact with the plastic intake manifold, from being higher than the plastic starts to warp.
- this temperature there are two possible paths, one by indirect methods and the other, the best, by measuring it directly, providing a temperature sensor in direct contact or through low thermal impedances known to the heater module support.
- thermocouple (as proposed by the invention patent application PCT / ES02 / 00369 of the same applicant) in which a resistance with integrated thermocouple is shown or by welding a thermocouple on the heating element, however it is an expensive solution.
- the preferred assembly is the one that allows the temperature sensor to be included in the control circuit and this in the frame, so that a direct measurement of the temperature of said frame is achieved.
- this assembly should be noted that prevents the direct connection of the heating element to the battery, which will allow us to mount it safely on the plastic manifold, since only the heating element can be fed through the circuit of control and this will require that the temperature sensor is located at the measuring point and working.
- the module provides a robust temperature measurement because there are no cables or connections. - In manufacturing, the position of the temperature sensor on the frame itself determines that the protection temperature has a low dispersion. Due to its compact nature, the mechanical robustness is very high and the module withstands well the typical vibrations of a combustion engine.
- Figure 1. Shows a front view of the intake gas heater module of an automotive engine in which its constituent elements are shown.
- Figure 2. Shows a representation of the heating element consisting of one or more tape type resistors.
- Figure 3. Shows a perspective view of the control circuit in which the power switches, the control logic and the integrated temperature sensor are observed.
- Figure 4. Shows a schematic diagram showing the connections of the heater module with the electronic control unit and with the battery.
- Figure 5. Shows the heater module incorporated in a manifold, in which the temperature sensor embedded in the wall of the plastic manifold has been represented.
- Figure 6. Shows the heater module incorporated in a collector, in which the thermocouple type temperature sensor is represented as part of the heating element.
- Figure 7. Shows the heater module incorporated in a manifold, in which the temperature sensor downstream of the heater module is shown.
- Figure 8. Shows the heater module incorporated in a collector, in which the temperature sensor integrated in the control circuit has been represented.
- the intake gas heater module of an automotive engine that is the object of this invention is of the type used for heating the gases circulating in the duct of admission (13) by means of a heating element (1) powered by a battery and receiving its power from a power control circuit (4) commanded by an electronic engine control unit (ECU) (12).
- ECU electronic engine control unit
- the heater module stands out mainly because it incorporates a metal frame (2), preferably of aluminum, in which the power control circuit (4) is attached and in which the heating element (1) is mounted ) both forming the same module in order to allow electronic control of the temperature of the intake gases.
- the power control circuit (4) is preferably mounted on a ceramic substrate (10) adhered with a thermoconducting product to the frame (2) and incorporates essentially a control logic (8) to which a temperature sensor is connected (3), and at least one power switch (6) that controls the heating element (1) consisting of one or more resistors, preferably a power switch (6) for each resistor.
- a power connection (9) that is directed to the positive of the battery, an electrical connection, cable or soldered terminal (5) integrated in the module impossible to manipulate or feed from the outside that it connects it with the heating element (1), which is connected to the mass of the frame (2) at its other end, and a control connector (7) that sends the temperature signals captured by the temperature sensor (3 ) to the electronic control unit of the motor that responds by sending signals to the control circuit (4) to regulation of the power applied on the heating element (1).
- the heating elements (1) consist of tape-type resistors that are mounted on ceramic insulators (11) on which the resistances are supported and expanded in order to absorb dilations avoiding their deformations, the ceramic insulator (11) consisting of an independent element for each resistance or forming a single monobloc piece that covers all the resistors.
- the intake gas heater module is mainly applicable for intake manifolds (14) composed of low working temperature materials, especially plastic manifolds.
- thermosensor (3) is integrated in the control circuit (4) to effect precise temperature control, as shown in the figure
- the temperature sensor (3) can be embedded embedded in the wall of the plastic manifold (14), as seen in Figure 5, can be integrated in the heating element itself (1), as shown in Figure 6 or the heating element (1) can be arranged downstream, as shown in Figure 7.
