Definitions
- the present invention relates to a regenerative cooling system which constitutes, among other things, an improvement of the transfer-expansion and regeneration heat engine which was the subject of the patent application No. FR 51593 of 25 February 2015 belonging to the applicant, and the patent published on 1 September 2016 under No. US 2016/0252048 A1, which also belongs to the applicant.
- the regeneration Brayton cycle ordinarily used by means of centrifugal compressors and turbines is known.
- said cycle leads to engines which deliver a significantly higher efficiency than that of spark ignition engines.
- This yield is comparable to that of fast diesel engines.
- it remains inferior to that of two-stroke very slow displacement diesel engines found for example in naval propulsion or stationary electricity production.
- regenerative Brayton cycle centrifugal and turbine engines deliver their best performance over a relatively narrow power and speed range.
- their response time in power modulation is long.
- Their field of application is in these various limited ways and they are difficult to adapt to land transport and particularly, to the automobile and heavy goods vehicles.
- the thermal transfer-expansion and regeneration engine object of the patent application No. FR 51593 was provided to overcome these defects.
- Said engine has the particularity of implementing the regenerated Brayton cycle no longer by means of centrifugal compressors and turbines, but by means of volumetric machines or at the very least, by means of a volumetric expansion device constituted around a "cylinder regulator ".
- each end of said expansion cylinder is closed by a cylinder head of a pressure reducer cylinder.
- said cylinder houses a double-acting expansion piston to form two transfer-expansion chambers of variable volume.
- Said piston can move in the expander cylinder to transmit a work to a power output shaft via a rod and a crankshaft known per se.
- the volumetric expansion valve is actually constituted by a cylinder, which does not teach the state of the art mentioning related machines.
- US Patent 2003/228237 A1 of December 1, 2003 includes a compressor, a heat exchanger regeneration, a heat source and a pressure reducer, however, the latter is not a cylinder but what the inventors of the said patent called a "gerotor".
- the second condition is that the inlet and the outlet of the gases in the regulating cylinder are regulated by duly phased intake and exhaust metering valves, which leads to the "pressure / volume" diagram which is dedicated to a figure in the Patent Application No. FR 51593.
- the third condition is that the sealing device between the piston and the cylinder can operate at a very high temperature.
- the transfer-expansion-regeneration thermal motor described in patent application No. FR 51593 fulfills this third condition by exposing an innovative air-cushion segment consisting of an inflatable and expandable perforated continuous ring housed in a ring groove formed in the piston regulator. Said ring defines with said groove a pressure distribution chamber connected to a source of fluid under pressure.
- This new sealing device and without direct contact with the expander cylinder makes it possible to operate at high temperature of said cylinder, while the intake and exhaust metering valves that comprise the yokes which close said cylinder can maximize the efficiency of the cylinder. thermal engine with transfer-relaxation and regeneration.
- the patent application FR 15 51593 provides that the expansion cylinder, the cylinder heads of the expander cylinder and the expansion piston of the transfer-expansion and regeneration thermal engine can be made of materials resistant to very high temperatures such as ceramics based on alumina, zirconia or silicon carbide.
- the improvements described in the patent applications No. FR 58585 and No. FR 58593 do not change the fact that if the temperature of the gases introduced into the expander cylinder of said engine is, for example, one thousand three hundred degrees Celsius, the temperature of the internal walls of said cylinder will be locally close to one thousand three hundred degrees Celsius, with an average temperature of said walls approaching, for example, one thousand degrees Celsius.
- the temperature of said gases thus directly determines the temperature at which the materials constituting the hot parts of the expander cylinder of the thermal transfer-expansion-regeneration motor must resist.
- the temperature resistance of said materials determines the maximum efficiency accessible by said engine.
- the materials that can withstand the very high temperatures in question are relatively few in that they must also offer a high mechanical resistance to these same temperatures, in addition to being resistant to corrosion. and oxidation.
- Said materials are mainly ceramics such as alumina, zirconia, silicon carbide or silicon nitride. These materials are hard and difficult to machine. As a result, the cost price of the finished parts is relatively high, which is a brake on the adoption by the automotive industry of the thermal transfer-expansion and regeneration engine that is the subject of the patent application FR 15 51593. Indeed, Since this industry is aimed at the mass market, it has a high sensitivity to manufacturing costs, which must remain as low as possible.
- the inner walls of the expansion cylinder of said engine should remain at a maximum temperature of, for example, seven to nine hundred degrees Celsius. Indeed, at such temperatures, materials more common and cheaper to produce and machine than ceramics such as cast iron or stainless or refractory steels can be used to manufacture said expander cylinder. This also applies to the yokes and their respective plenums and ducts which cooperate with said cylinder.
- the regenerative cooling system according to the invention is mainly intended for the transfer-expansion and regeneration thermal engine that is the subject of the patent application FR 15 51593 belonging to the applicant.

- the effective cross-section of the enclosure bypass duct 87 may optionally be regulated by a flow control valve 85, the latter being able - depending on its position - to prohibit, let free, or restrict the flow of gas working 81 in said bypass duct 87.
- the outside of the cooling enclosure 79 may be coated with a heat shield 88 which may be made of any heat-insulating material known to those skilled in the art and which may furthermore the cooling chamber 79 - coating the various hot pipes and members that constitute the regenerative heat engine 1.
- said heat shield 88 is provided to prevent any loss of excessive heat which is unfavorable to the efficiency of the regenerative heat engine 1.
- the regeneration engine 1 here comprises a two-stage compressor 2 which notably consists of a low-pressure compressor 35 which sucks working gas 81 into the atmosphere via an inlet duct compressor 3, the output of said low-pressure compressor 35 being connected to the inlet of a high-pressure compressor 36 via a compressor intercooler 37.
- FIG. 1 illustrates that at the outlet of the high-pressure compressor 36, the The working gas 81 is expelled into the regeneration high-pressure pipe 6 which comprises the regeneration heat exchanger 5, which in this case is a countercurrent heat exchanger 41 known per se. Assume here that the working gas 81 is expelled from the high-pressure compressor 36 under a pressure of twenty bars and at a temperature of two hundred degrees Celsius.
- the working gas 81 While circulating in the regeneration high-pressure conduit 6, the working gas 81 is preheated to a temperature of six-hundred-fifty degrees Celsius by the hot working gas 81 which flows through the adjacent low-pressure regeneration line 7.
- the efficiency of the regeneration heat exchanger 5 is one hundred percent. This implies that the working gas 81 circulating in the regeneration low-pressure line 7 enters the latter at a temperature of six hundred and fifty degrees Celsius and leaves said duct 7 at a temperature of two hundred degrees Celsius before be released into the atmosphere via the motor outlet conduit 33, while the working gas 81 which flows in the regeneration high-pressure conduit 6 enters the latter at a temperature of two hundred degrees Celsius to come out at a temperature of temperature of six hundred and fifty degrees Celsius.
- said working gas 81 is then superheated at a thousand-four hundred degrees Celsius by the heat source 12 which - according to this embodiment - consists of a fuel burner 38.
- the working gas 81 is conveyed via a hot gas intake duct 19 to the gas expander 78 which is nothing other than the expander cylinder 13 of the transfer-expansion and regeneration thermal engine.
- the hot gas inlet duct 19 is preferably made of ceramic with high temperature resistance until it is connected to a cylinder head of the expander cylinder 14 covering either end of the expander cylinder 13. the temperature of said duct 19 remains approximately equal to one thousand four hundred degrees Celsius so that the working gas 81 flowing in said duct 19 retains its temperature throughout its course.
- each end of the expander cylinder 13 is capped with a cylinder head of the expander cylinder 14 so that two decompressor-expansion chambers 16 are defined with a double-acting expansion piston.
- each cylinder head has an intake metering valve 24 and an exhaust metering valve 31.
- the transfer-expansion and regeneration heat engine being hot, the expansion cylinder 13 and the cylinder cylinder cylinder 14 are maintained at a temperature of about seven hundred degrees Celsius.
- said cylinder 13 and said cylinder heads 14 are made of a less expensive and more current material than ceramic, such as stainless steel or ferritic silicon cast iron.
- the double-acting expander piston 15 is itself, and according to this non-limiting embodiment of the regenerative cooling system 100 according to the invention, manufactured in silicon nitride.
- the average operating temperature of said piston 15 is of the order of eight hundred degrees Celsius.
- said piston 15 is connected by mechanical transmission means 19 to a power output shaft 17, said means 19 being in particular constituted by a connecting rod 42 articulated around a crank 43.
- the working gas 81 brought to a pressure of twenty bars and at a temperature of fourteen hundred degrees Celsius is thus introduced into one or the other transfer-expansion chamber 16 by the corresponding metering inlet valve 24.
- said gas 81 By passing through the orifice kept open by the intake metering valve 24, said gas 81 begins to cool slightly, in particular in contact with the internal walls of the cylinder cylinder 14 that it passes through, and the internal walls of the cylinder. the transfer-expansion chamber 16 in which it is introduced for the purpose of being expanded by the double-acting expansion piston 15. Said walls are - as we have seen previously - maintained at seven hundred degrees Celsius by the regenerative cooling system 100.
- the working gas 81 loses an average of 100 degrees Celsius by licking the internal walls of the cylinder cylinder 14, and those of the transfer-expansion chamber 16.
- the temperature of the gas Working 81 has fallen during its transfer from the hot gas inlet duct 19 to the transfer-expansion chamber 16 to go from one thousand four hundred degrees Celsius to one thousand three hundred degrees Celsius.
- the pressure of said gas 81 has dropped to about one absolute bar. It is the same for the temperature of said gas 81 which has increased from one thousand three hundred degrees Celsius to five hundred and fifty degrees Celsius.
- the exhaust metering valve 31 opens and said piston 15 expels said gas 81 into the enclosure inlet conduit 84 which conveys said gas 81 to enclosure inlet port 82.
- the working gas 81 then enters the gas flow space 80 and then flows through this space to the enclosure outlet port 83. In doing so, said gas 81 licks the outer walls
- the outer walls have been provided wholly or partly roughened and / or interspersed with geometric patterns in order to produce a convective forcing forcing the working gas 81 to take more or less heat from the said expander cylinder 13 and the expander cylinder yokes 14. walls when said gas 81 flows in contact with said walls.
- the internal geometry of the cooling chamber 79 and / or the external geometry of the expansion cylinder 13 and / or the external geometry of the cylinder cylinder 14 can advantageously form channels that force all or part of the working gas 81 to following a route or several simultaneous routes to go from the speaker input port 82 to the speaker output port 83 via the gas flow space 80.
- the double strategy of convective forcing and forced route of the working gas 81 makes it possible to choose, firstly, the heat export zones from the hot external walls of the expander cylinder 13 and the cylinder of the expander cylinder 14 to the said gas 81, secondly, the chronological order of scanning of said zones by said gas 81, and third and last, the intensity of the convective forcing along the route of said gas 81.
- the temperature of the working gas 81 subtracts heat from the hot external walls of the expander cylinder 13 and the cylinder cylinder cylinder 14 to the point that the temperature of said gas 81 progressively goes from five hundred and fifty degrees Celsius to six hundred and fifty degrees Celsius.
- the latter homogenizes the temperature of the expander cylinder 13 and cylinder cylinder cylinder 14 said temperature being maintained in the vicinity of seven hundred degrees Celsius.
- the working gas 81 having reached its new temperature of six hundred fifty degrees Celsius, said gas 81 reaches the speaker output port 83 and rejoins the low-pressure regeneration line 7 via the speaker output conduit 86.
- the heat extracted from the expander cylinder 13 and cylinder cylinder cylinder 14 to maintain a temperature of the order of seven hundred degrees Celsius is in no way dissipated in pure loss.
- said heat is reintroduced into the thermodynamic cycle of the regenerative heat engine 1 to substitute for a portion of the heat to be supplied by the fuel burner 38 to bring the working gas 81 to a temperature of eighteen hundred degrees Celsius before the latter is directed towards the expander cylinder 13 and then introduced into the transfer-expansion chambers 16.
- the enclosure bypass duct 87 which comprises a flow control valve 85.
- the speaker output conduit 86 also includes a flow control valve 85.
- the flow control valve 85 of the enclosure bypass duct 87 opens said bypass duct 87 while the flow control valve 85 the enclosure outlet duct 86 closes said outlet duct 86.
- This has the effect of preventing the exhaust gas 81 expelled from the transfer-expansion chambers 16 by their respective exhaust metering valve 31 to pass through the space of circulation of gas 80 to join the low-pressure regeneration line 7. Said gas 81 therefore joins said duct 7 directly via the enclosure bypass duct 87.
- valves 85 are seldom either fully open or fully closed, and that said valves 85 can be kept ajar to regulate the temperature of the expander cylinder 13 and cylinder cylinder expander 14 without sudden change operating gas flow 81 circulating in the gas circulation space 80.
- control device formed for example of at least one temperature sensor and a microcontroller known per se, which make it possible to drive servomotors of any type whatsoever which each operates a flow control valve 85 opening or closing.
- the flow control valves 85 can also be connected to each other by a mechanical connection to share the same servomotor. In this case, said connection ensures that when the first said valve 85 is closed the second is opened, and vice versa.
- the regenerative cooling system 100 brings many advantages, in particular to the implementation of the transfer-expansion and regeneration thermal engine which is the subject of patent application No. FR 51593 belonging to to the applicant.
- the expander cylinder 13 and the cylinder cylinder cylinder 14 expander being colder, it is possible to use materials with very low thermal conductivity and high compressive strength such as quartz to achieve the pillars recesses of the double-acting pressure-compensating cylinder with adaptive support object of the patent application No. FR 58585 of 14 September 2015 belonging to the applicant. Indeed, if quartz is not compatible with a temperature of one thousand three hundred degrees Celsius, it is perfectly compatible with a temperature of seven hundred degrees Celsius. It should be recalled here that the double-acting, adaptive-support-type expansion cylinder in question is one of the key improvements of the transfer-expansion-regeneration thermal engine.
- the cylinder cylinder cylinders 14 being maintained at seven hundred degrees Celsius, they can receive pre-existing silicon nitride valves compatible with these temperature levels.
- Such valves have for example been developed by the company "NGK” and have been the subject of research on their low-cost industrialization, particularly in the framework of project No. G3RD-CT-2000-00248 entitled “LIVALVES”, financed in the framework of the fifth FP5-GROWTH European Framework Program.
- the air cushion segment as provided in applicant's patent application FR 51593 can be made of a superalloy durably resistant to these temperature levels, without risk for said segment to be subjected to a temperature significantly higher than said seven hundred degrees Celsius, especially when the heat transfer engine-relaxation and regeneration is stopped and before that it has cooled.
- the regenerative cooling system 100 makes it possible to limit the temperature at which the heat shields are subjected. 88, which surround the expander cylinder 13 and the cylinder cylinder cylinder 14.
- the cooling chamber 79 is inserted between said screens 88 on the one hand, and said cylinder 13 and said cylinder heads on the other. The cost price and durability of said screens 88 are thus improved in large proportions.
- the regenerative cooling system 100 makes it possible to decouple the existing relationship according to the patent application No. FR 51593 between the temperature resistance of the materials constituting the expander cylinder 13 and the cylinder heads of the expander cylinder 14. on the one hand, and the temperature of the working gas 81 coming out of the fuel burner 38 on the other hand.
- the regenerative cooling system 100 can advantageously be applied to any other regenerative heat engine 1 of which the configuration and the temperature characteristics are compatible with said system 100.
