Definitions
- the subject of the present invention is a device for thermal regulation of a circulating fluid used in particular for regulating the temperature of tools or reactors.
- Such devices intended to regulate the temperature of a tool for molding plastic materials by means of a heat transfer fluid circulating under the action of a pump already exist.
- the temperature of the fluid can be increased by means of electric heating resistances or decreased by means of a second cold fluid passing through an exchanger, the assembly being able to be controlled by means of an electronic regulator connected to one or more thermocouples judiciously arranged on the path of the heat transfer fluid and by various safety devices.
- these devices include a cooler heater for the heat transfer fluid formed by a reservoir inside which is arranged an electrical heating resistor and a cooling fluid circuit consisting of a coil, the electrical resistors of course being arranged at the inside a shielded tube, as described in document BF - A. 2658332 (VULCANIC SA).
- control devices include a plate heat exchanger.
- a plate heat exchanger consisting of a stack of plates the fluid to be cooled and the cold fluid circulate in two different circuits without contact with each other, on either side of each plate.
- the regulating devices comprising such plate exchangers are bulky because the heating resistors must obviously be outside and quite spaced from the said exchangers, hence a large volume of the assembly and the need to have a large amount of circulating heat transfer fluid.
- the object of the present invention is to remedy these drawbacks by producing a device for regulating the temperature of a fluid by means of a heat exchanger constituted by a stack of corrugated or ribbed plates defining by means of seals arranged between said plates, alternating circuits of coolants and coolant.
- the device according to the invention is notably characterized in that the aforementioned stack is formed of a plurality of elementary assemblies each comprising in order: 5 - A refrigerant circuit
- the electrical resistance is embedded in a suitable material, for example ceramic, electrically insulating but heat conducting, which is shaped identically to the ribbed plates so that it 'insert without difficulty between said plates.
- a suitable material for example ceramic, electrically insulating but heat conducting, which is shaped identically to the ribbed plates so that it 'insert without difficulty between said plates.
- the electrically insulated electrical resistance can be embedded in a conductive material such as aluminum, the walls of which conform to the corrugated shape of the usual plates, which makes it possible to remove them.
- Another characteristic of the invention resides in that the alternating circuits of coolant and heat transfer fluid are defined by means of seals having a thickness sufficient to be compressed between two ribbed plates.
- the circuits of coolant and heat transfer fluid circulate in the stack of the ribbed plates by means of inlet and outlet orifices made in said plates so as to that the fluids cross them perpendicular to their plane.
- the regulating device according to the invention is compact while having a large heat exchange surface and requires only a small volume of heat transfer fluid, generally water or oil. It also makes it possible to have a very short response time, the fluid being brought quickly to the desired temperature.
- the fluid thus regulated may in particular be a circuit of heat transfer liquid circulated by a pump and serving to regulate the temperature of tools or reactors, for example from 5 ° to 250 ° C. Depending on the regulation and the flow rate envisaged, realizes an exchanger comprising a stack of more or less large plates between which are inserted a more or less large number of heating plates.
- FIG. 2 is a partial schematic view showing the integration of a heating plate between the plates of an exchanger according to the invention.
- FIG. 3 is a plan view of an exchanger plate with a heating plate according to line III-III of FIG. 2.
- Figures 4 & 5 are views, in partial section, of a stack of plates with a fluid circulation orifice.
- Figure 6 is a partial sectional view of a heating resistor having the same configuration as the ribbed plates.
- FIG. 7 is a diagram of a temperature control device according to the invention.
- FIG. 1 is a block diagram of a basic element intended to constitute the temperature control device according to the invention, we see that it is formed of a stack 1 of corrugated or ribbed plates 2 of a type known for this application, for example made of stainless steel. These plates define by means of seals, not shown, but conventional circuits 11-13 alternating heat transfer fluids (FC) and refrigerants (FR).
- FC alternating heat transfer fluids
- FR refrigerants
- This basic element comprises ribbed plates 2a between which pass, in order:
- a heating means 7 consisting of an electrical resistance 3 disposed between plates 4 of refractory material (ceramic).
- the electrically insulated electrical resistance (3) can be embedded in a conductive filling material such as aluminum, the walls of which conform to the corrugated shape of the usual plates, which advantageously makes it possible to remove them, resulting in substantial savings. .
- This exchanger is formed by the stacking of a number of plates 2 having in known manner scrolls, or corrugations 10 to force the circulating fluid to create turbulence; these plates 2 are provided with orifices 5 at each end to allow the entry and exit into their respective cavities of the heat transfer fluid
- FC coolant
- FR coolant
- the seal 6 is sectioned around orifice 5 every second time, as seen in FIG. 2.
- a heating means 7 which may consist of one or more electrical resistances 3, arranged in a refractory material in the form of a plate 4, all of the resistors being connected to an electrical source, not shown.
- a seal 8 of circular section is placed around the orifice 5 where the fluid circulates.
- This seal 8 can have any cross section, but its thickness must be greater than the thickness of the heating plate 4 plus the distance separating two plates 2, so that during assembly it is crushed and thus ensures perfect sealing. It must also be made of material resistant to the maximum temperature • envisaged.
- the cells 10 formed above and below the heating element 7 can be filled with refractory cement or a similar material which is a good conductor of heat.
- two insulating plates are arranged, conventionally held by tie rods.
- Figure 3 there is shown a plan view of the plates 2 along the line III-III of Figure 2, showing the orifices 5a for the passage of the coolant (FC) and those 5b of the coolant (FR) as well as the 'location of seals 8 and 6, the hatched central zone represents the location of the heating resistor 3. As can be seen, the active part of the heating elements is located below the seal 6.
- FIGS. 4 and 5 two alternative embodiments have been shown, showing the stack of plates 2 forming the exchanger of the device according to the invention, in which the seal 8 of the embodiment of FIG. 2 has been removed and replaced by a metal sleeve 20 welded to the plates 2b in order to ensure a perfect seal (fig- 4).
- the plates 2b have been shaped so that they can be welded at 61 around the opening 5 of the passage of the fluid 3 and at their periphery 60.
- FIG 6 there is shown another variant in which the electrical resistance 3 is embedded in a ceramic material 4, for example, insulating but good conductor of heat, which is shaped identically to the ribbed plates 2b so as to s 'insert without difficulty between said plates.
- An orifice 5 is provided for the passage of the fluid.
- This embodiment eliminates the seal 8.
- Figure 7 is a diagram of the temperature control device according to the invention. As can be seen in this figure, the device according to the invention is very simple.
- It comprises a plate exchanger 1 with its electrical heating resistance (s) 3, crossed on the one hand, by a fluid circuit 11 coolant (FC) in forced circulation by means of a pump 12 to the mold of an injection molding machine or to the reactor of an equipment, not shown, and on the other hand, by a water circuit 5 cold 13.
- FC coolant
- the heat transfer fluid circulates from the plate exchanger 1 to the tooling in a closed circuit and without an intermediate storage tank.
- Three solenoid valves 14, 15 and 16 are provided 10 to isolate the heat transfer fluid (FC) and limit leaks in the closed circuit 11 which goes to the mold or the reactor.
- the invention is also provided for taking
- the 20 device can, if necessary, regulate the temperature if the mold or the reactor does not include a temperature probe.
- the device according to the present invention can be used not only for the
