  • the sleeve 50 internally contains a venting valve of which only the bleed screw 36 is visible in the figure.
  • the electric heating element 2 is presented in a compact block which it suffices to connect to the electric network by the cord L to obtain a rise in temperature of the liquid contained in the radiator to the desired value. and to regulate it by the thermostat.
  • the expansion compensation device 3 comprises a pneumatic chamber 48 immersed in the liquid and which, by variation in volume following a deformation of its wall 32 as a function of the pressure inside the radiator, ensures a constant mass heat transfer liquid.
  • variable chamber makes it possible to avoid noises during the convection of the liquid in the event of excess air.
  • the heating element and the expansion compensation device are both provided, as already said, with a standard threaded plug so that they can be installed on an existing radiator, for example.
  • thermostatically controlled heating block 2 is mounted in place of the drain plug and the device 3 in place of the drain plug.
  • the operation is carried out by rotation of the graduated control button 5 ( Figure 2 or 5) to the position corresponding to the value of the desired temperature for the heat transfer liquid (approximately 30 to 90 ° C).
  • the heating resistor 6 enters into service and raises the temperature of the radiator until the thermostat set by button 5 is triggered, which takes place when the set value is reached.
  • FIGS 2 and 5 show two different variants of the thermostat of the heating element, mechanical and electronic respectively.
  • the latter is secured at its end to an internal rod 8 with a diameter of 2.5 mm in material having a coefficient of expansion substantially lower than the tube of the probe 7.
  • the support 9 acts on an insulating material stop 10 by means of the rocker 11, which itself actuates a rocking contact 12.
  • the tensile force exerted by the rod 8 reaches the rocking value of the rocking contact support 12, it changes state and interrupts the passage of the heating current Ir (fig. 4).
  • the liquid from the radiator cools by heat exchange with the ambient medium.
  • the regulation on AT 2 is thus carried out over time, and the diagram of FIG. 4 shows the states of passage of the current Ir in correspondence with the regulation curve of FIG. 3.
  • the reference for obtaining an adequate range Af i of the thermostat is made by the value of the thread pitch of the control button 5 and by the adjustment of the height positioning of the needle 16 which presses on the support 9 of the rocker spring 11.
  • the positioning at reference zero is obtained by a small stop spring 17 which cooperates with a rotary cam 18 fixed to the needle 16 for the angular adjustment of the control 5.
  • a helical spring 19, working in compression, ensures the return of the support 9 for operation of the rocker spring 9 to a value of approximately 4 kgf, for example.
  • the heating of the probe 7 is transmitted by contact to a thermistor 20 embedded in the end of the latter.
  • the decrease in the CTN value Modifies the current and the voltage of the bridge formed by resistors 21 and 22, causing, via the integrated circuit 23 of type MFC 8070, the change of state. ordering a triac 24.
  • the electrical connections inside the cover 46, covering the plastic plug 27, are made by standardized plug-in lugs 28 and plugs 47.
  • the shielded resistor 6 and the thermal probe 7 ′ are sealed by two O-rings 29 and 29 ′ compressed by a support core 30 of elastomer force-fitted.
  • this device 3 essentially comprises a resistant but deformable wall 32, shaped like an "accordion type” bellows and internally defining a pneumatic chamber 48.
  • This wall is held in a body 50 serving as a plug-thanks to its threaded anterior bearing 41 which is screwed into the bleed orifice of the upper manifold of the radiator (not shown in Figure 7).
  • the tightness of the assembly is ensured by crushing the end of the wall 32 by means of a core 42 inserted by force which is pierced longitudinally by a channel 33 putting the chamber 48 in communication with the external atmosphere.
  • the threaded surface 41 also has a channel for placing the interior enclosure of the radiator in communication with the exterior at its upper end.
  • This channel 51 extends into the body 50 and opens into an internal cavity 52 comprising an orifice 35 with the outside, normally closed by a bleed screw 36.
  • the orifice 35 After opening thereof, the orifice 35 has the conventional role of evacuating the air occasionally present in the radiator.
  • the expansion chamber 48 during the rise in temperature compresses under the pressure of the liquid and the excess air is evacuated through the passage 33.
  • the consistency and shape of the wall 32 are defined to allow a modification of the volume of the chamber 48 in order to compensate for the effects of the expansion of the liquid and thus maintain a constant mass of liquid in the radiator by avoiding overpressures.
  • the wall 32 may be made of flexible plastic material in which are embedded metallic filaments 34 which give it the desirable mechanical strength.
  • the wall can be made of stainless steel, therefore resistant to corrosion.
  • the inlet R 1 and outlet R 2 valves can be manual or electrically controlled, subject to the commissioning of the heating block 2, when the button 5 is operated.

Their presence is however an important advantage, since they allow, by cutting the liquid mass of the radiator from the rest of the circuit, to avoid heat loss by convection within the circuit, outside the place that is desired specifically heat.
  • the heating block 2 like the device 3, are perfectly adaptable to all types of radiator. If necessary for a larger diameter of the radiator orifices, a threaded sleeve inside and outside will ensure adaptation.
  • the heating resistor 6 ′ is shaped as a “U between the branches of which the probe 7 ′ is placed to reduce the overall dimensions in width.
  • the resistor and the probe are held at their ends in a plastic washer 53 and the resistance is held by a spacer 54 placed between its two branches.
  • This also serves as an introduction guide, avoiding, by virtue of two lateral protrusions 55, the coming into contact of the resistance tube with the internal wall of the collector a.
  • This sub-assembly is placed in the threaded anterior surface 4 ′ of the body 27 ′, hollowed out for this purpose and having an oblong opening 56 for the passage of the resistance and the soda.
