Description

Technical Field

[0001] The present invention relates to the technical field of heaters, and specifically to an integrated structure of MCH heating and a compressor. Background Art

[0002] MCH is a metal-ceramic heating element. MCH refers to a ceramic heating element formed by printing metal tungsten or molybdenum-manganese slurry on a ceramic tape casting blank, screen-printing and shaping into a film, wrapping the rod and static pressing, and then continuously sintering in a high-temperature tunnel furnace under a hydrogen-nitrogen atmosphere protection at 1600 °C for 24H. The ceramic and metal are sintered together, and it has the advantages of corrosion resistance, high temperature resistance, long service life, high efficiency and energy saving, uniform temperature, good thermal conductivity, and fast temperature rise. With the development of new energy vehicles, the technology of components is also changing with each passing day, especially in the aspects of integration, lightweight, and low-cost routes. As a core component of the thermal management of new energy vehicles, the electric compressor plays an increasingly crucial role.

[0003] At present, the original heating structures of new energy vehicles using air-heated PTC and water-heated PTC heaters have large space occupation in the vehicle, low integration, and uneven fluid heating, which easily result in local overheating and underheating, with temperature differences, slow temperature rise, and affect the heating speed of the fluid. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] An integrated structure of MCH heating and a compressor, comprising:

[0006] A compressor pump body, and a controller installed at the bottom of the compressor pump body. An electrical connector is installed at the side of the top of the controller, and a heating mechanism is installed at the bottom of the controller;

[0007] The heating mechanism includes an aluminum casting flow channel, an inlet pipe, and an outlet pipe. The aluminum casting flow channel is installed at the bottom of the controller. The inlet pipe and the outlet pipe are sequentially installed at the side of the surface of the aluminum casting flow channel, and the inlet pipe and the outlet pipe are communicated with the aluminum casting flow channel. A end cover is fixedly connected to the middle of the top of the aluminum casting flow channel. A ceramic heating tube is installed at the bottom of the inner cavity of the aluminum casting flow channel, and the ceramic heating tube is hermetically installed with the bottom of the aluminum casting flow channel. The bottom end of the aluminum casting flow channel extends to the bottom of the aluminum casting flow channel. A heating core pressing plate is fixedly installed at the bottom of the aluminum casting flow channel, and a PCB connecting plate is fixedly installed at the bottom of the heating core pressing plate. The integration of the heating mechanism and the compressor pump body integrates the heat exchange flow channel and the heating component onto the compressor pump body, and the controller is integrated with the compressor pump body, reducing the use of control chips and also reducing the number of high and low voltage contact parts.

[0008] Preferably, the liquid inlet pipe and the liquid outlet pipe are installed at the same height, the end cover is hermetically installed between the top of the cast aluminum runner, and the PCB connecting plate is installed directly below the ceramic heating tube.

[0009] The heating mechanism is directly electrically connected to the compressor pump body through a terminal block to realize the function of controlling the heating mechanism and the compressor pump body together, so as to achieve an integrated design, without occupying a large space, and meeting the goals of small volume and low cost.

[0010] Preferably, there are two heating core pressing plates, and the two heating core pressing plates are symmetrically installed along the central axis in the middle of the cast aluminum runner. The ceramic heating tubes are vertically installed. There are four ceramic heating tubes, and the four ceramic heating tubes are evenly distributed at the bottom of the inner cavity of the cast aluminum runner. The ceramic heating tubes pass through the center of the heating core pressing plate.

[0011] The ceramic heating tubes are fixed by the heating core pressing plates, so that the ceramic heating tubes are firmly fixed and are not prone to loosening and skewing. Moreover, the ceramic heating tubes heat the fluid in the inner cavity of the cast aluminum runner, so that the temperature of the fluid in the inner cavity of the cast aluminum runner rises after being heated. There are four ceramic heating tubes, and the four ceramic heating tubes are evenly distributed at the bottom of the inner cavity of the cast aluminum runner, which promotes the uniform heating of the fluid in the inner cavity of the cast aluminum runner and is not prone to local overheating and too low temperature, and the temperature difference is small.

[0012] Preferably, a flow guiding mechanism is installed in the middle of the inner cavity of the cast aluminum runner. The flow guiding mechanism includes a middle flat plate. One end of the surface of the middle flat plate is fixedly connected to the middle of the inner wall of the cast aluminum runner. A single-sided bending plate is fixedly connected to the side of the inner wall of the cast aluminum runner. A double-sided bending plate is fixedly connected to the inner wall of the cast aluminum runner, and the double-sided bending plate is installed between the middle flat plate and the single-sided bending plate. An anti-backflow component is installed between the surface of the middle flat plate and the surface of the double-sided bending plate. By installing the end cover on the top of the cast aluminum runner, a closed space is formed in the inner cavity of the cast aluminum runner. The fluid enters the inside of the cast aluminum runner from the liquid inlet pipe, and the fluid will be guided by the single-sided bending plate, so that the fluid fully contacts the two ceramic heating tubes on the side of the inner cavity of the cast aluminum runner, and then can be preliminarily heated. As the flow path formed by the double-sided bending plate, the middle flat plate and the single-sided bending plate is in a curve S shape, the flow resistance of the fluid in the cast aluminum runner can be increased. At the same time, before the fluid flows out from the liquid outlet pipe, it will be heated by the other two ceramic heating tubes again, the temperature rises quickly, and it is helpful for the rapid heating of the fluid.

[0013] Preferably, there are two double-sided bending plates, and the two double-sided bending plates are symmetrically installed along the middle flat plate. There are two single-sided bending plates, and the two single-sided bending plates are symmetrically installed along the middle flat plate.

[0014] Preferably, the anti-backflow component includes a square frame body, which is fixedly connected between the surface of the middle flat plate and the surface of the double-sided bent plate. A wedge plug is installed at the liquid outlet end of the surface of the square frame body. A first elastic sheet is fixedly connected between the surface of the wedge plug and the surface of the middle flat plate, and a second elastic sheet is fixedly connected between the surface of the wedge plug and the surface of the double-sided bent plate. As the fluid flows in the flow channel composed of the double-sided bent plate, the middle flat plate and the single-sided bent plate, under the action of the fluid pressure, the fluid exerts a driving force on the wedge plug, causing the wedge plug to move outward and compress the first elastic sheet and the second elastic sheet, so that the channel inside the square frame body is opened, making the fluid flow smoothly. When the fluid is about to flow reversely, the driving force of the fluid on the wedge plug disappears, and under the elastic force of the first elastic sheet and the second elastic sheet, the wedge plug timely blocks the channel of the square frame body, and there will be no backflow situation.

[0015] Preferably, the surface of the wedge plug fits the inner wall of the liquid outlet end of the square frame body. Both the first elastic sheet and the second elastic sheet are arc-shaped, and the first elastic sheet and the second elastic sheet are installed at the same height.

[0016] Preferably, anti-leakage mechanisms are installed at both ends of the liquid inlet pipe away from the cast aluminum flow channel and the liquid outlet pipe away from the cast aluminum flow channel. The anti-leakage mechanism includes a connecting ring, an annular groove and a conical connecting head. The connecting ring is threadedly installed with the liquid outlet pipe through a threaded groove. The annular groove is opened at the conical surface of the liquid outlet pipe surface. A right-angled tooth is fixedly connected to the outer circular surface of the connecting ring. An annular clamping groove is opened at the side of the outer circular surface of the conical connecting head. The conical connecting head is slidably installed with the right-angled end of the right-angled tooth through the annular clamping groove. A sealing ring is fixedly connected to the conical surface of the inner cavity of the conical connecting head. By the right-angled tooth protruding on the outer circular surface of the connecting ring, it is convenient to twist the connecting ring by the right-angled tooth, so that the connecting ring is threadedly connected and fixed with the liquid inlet pipe and the liquid outlet pipe. Then, through the pulling force of the right-angled tooth on the conical connecting head, the conical connecting head is sleeved on the end of the liquid inlet pipe and the end of the liquid outlet pipe. And the inner side surface of the sealing ring is embedded into the internal of the annular clamping groove, and the sealing ring is extruded by the conical connecting head, so that the sealing ring fills the gap between the inner wall of the conical connecting head and the end of the liquid inlet pipe and the end of the liquid outlet pipe, thus achieving the sealing effect and not being prone to leakage.

[0017] Preferably, the connecting ring, the annular groove and the liquid outlet pipe are installed at the same height. There are two right-angled teeth, and the two right-angled teeth are symmetrically installed along the central axis of the middle of the connecting ring.

[0018] When the right-angled tooth is driven to rotate by the connecting ring, and the conical connecting head is slidably installed with the right-angled end of the right-angled tooth through the annular slot, the right-angled tooth will only generate a pulling force on the conical connecting head, rather than a torsional force in the circumferential direction, which promotes the extrusion of the conical connecting head on the sealing ring, so that the sealing ring will not be skewed or displaced.

[0019] Preferably, the right-angled end of the right-angled tooth fits against the inner wall of the annular slot, the center of the sealing ring coincides with the axis at the middle of the conical connecting head, and the sealing ring and the annular groove are installed at the same height.

[0020] The present invention provides an integrated structure of MCH heating and a compressor. It has the following beneficial effects:

[0021] First, in the integrated structure of MCH heating and a compressor, the heating mechanism and the compressor pump body are integrated, so that the heat exchange flow channel and the heating component are integrated onto the compressor pump body, and the controller is integrated with the compressor pump body, reducing the use of control chips and also reducing the number of high and low voltage contact parts.

[0022] Second, in the integrated structure of MCH heating and a compressor, the heating mechanism is directly electrically connected to the compressor pump body through a wiring terminal, realizing the function of controlling the heating mechanism and the compressor pump body together, thus achieving an integrated design, without occupying a large space, and meeting the goals of small volume and low cost.

[0023] Third, in the integrated structure of MCH heating and a compressor, the ceramic heating tube is fixed by the heating core pressing plate, making the ceramic heating tube firmly fixed, not prone to looseness and skew, and the ceramic heating tube heats the fluid in the inner cavity of the cast aluminum flow channel, so that the temperature of the fluid in the inner cavity of the cast aluminum flow channel rises after being heated. And there are four ceramic heating tubes, and the four ceramic heating tubes are evenly distributed at the bottom of the inner cavity of the cast aluminum flow channel, promoting the uniform heating of the fluid in the inner cavity of the cast aluminum flow channel, not prone to local overheating and too low temperature, and the temperature difference is small.

[0024] Fourth, in the integrated structure of MCH heating and a compressor, the fluid enters the inside of the cast aluminum flow channel from the liquid inlet pipe, and the fluid is deflected by the single-sided bending plate, so that the fluid fully contacts the two ceramic heating tubes on the side of the inner cavity of the cast aluminum flow channel, and then can be preliminarily heated. As the flow channel composed of the double-sided bending plate, the middle flat plate and the single-sided bending plate is in a curve S shape, the flow of the fluid in the cast aluminum flow channel can be increased. At the same time, before the fluid flows out from the liquid outlet pipe, it will be heated by the other two ceramic heating tubes again, the temperature rises quickly, and it is helpful for the rapid heating of the fluid.

[0025] V. In the integrated structure of the MCH heater and the compressor, under the action of the fluid pressure, the fluid exerts a driving force on the wedge plug, causing the wedge plug to move outward and compress the first elastic sheet and the second elastic sheet, thereby opening the channel inside the square frame and making the fluid flow smoothly. When the fluid is about to flow reversely, the driving force of the fluid on the wedge plug disappears, and under the elastic force of the first elastic sheet and the second elastic sheet, the wedge plug timely seals the channel of the square frame, and no backflow will occur.

[0026] VI. In the integrated structure of the MCH heater and the compressor, by turning the connecting ring with the right-angled teeth, the connecting ring is threadedly connected and fixed to the liquid inlet pipe and the liquid outlet pipe. Then, through the pulling force of the right-angled teeth on the conical connector, the conical connector is sleeved on the ends of the liquid inlet pipe and the liquid outlet pipe, and the inner side of the sealing ring is embedded into the internal annular groove. And through the extrusion of the conical connector on the sealing ring, the sealing ring fills the gap between the inner wall of the conical connector and the ends of the liquid inlet pipe and the liquid outlet pipe, thus achieving the sealing effect and being not prone to leakage.

[0027] VII. In the integrated structure of the MCH heater and the compressor, when the connecting ring drives the right-angled teeth to rotate, and the conical connector is slidably installed through the annular groove with the right-angled end of the right-angled teeth, the right-angled teeth only generate a pulling force on the conical connector and will not generate a torsional force in the circumferential direction, promoting the extrusion of the conical connector on the sealing ring and preventing the sealing ring from being skewed and offset.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] The first embodiment is as Figures 1 to 4 shown, and the present invention provides a technical solution:

[0042] The heating mechanism 4 includes an aluminum casting runner 41, a liquid inlet pipe 42, and a liquid outlet pipe 43. The aluminum casting runner 41 is installed at the bottom of the controller 2. The liquid inlet pipe 42 and the liquid outlet pipe 43 are sequentially installed at the side of the surface of the aluminum casting runner 41, and the liquid inlet pipe 42 and the liquid outlet pipe 43 are communicated with the aluminum casting runner 41. A end cover 44 is fixedly connected to the middle of the top of the aluminum casting runner 41. A ceramic heating pipe 45 is installed at the bottom of the inner cavity of the aluminum casting runner 41, and the ceramic heating pipe 45 is hermetically installed with the bottom of the aluminum casting runner 41. The bottom end of the aluminum casting runner 41 extends to the bottom of the aluminum casting runner 41. A heating core pressing plate 46 is fixedly installed at the bottom of the aluminum casting runner 41. A PCB connecting plate 47 is fixedly installed at the bottom of the heating core pressing plate 46. Integrating the heating mechanism 4 and the compressor pump body 1 integrally enables the heat exchange runner and the heating component to be integrated onto the compressor pump body 1, and the controller 2 is integrated with the compressor pump body 1, reducing the use of control chips and also reducing the number of high and low voltage contact parts.

[0043] The liquid inlet pipe 42 and the liquid outlet pipe 43 are installed at the same height. The end cover 44 is hermetically installed with the top of the aluminum casting runner 41. The PCB connecting plate 47 is installed directly below the ceramic heating pipe 45.

[0044] The heating mechanism 4 is directly electrically connected to the compressor pump body 1 through a terminal to realize the function of controlling the heating mechanism 4 and the compressor pump body 1 together.

[0045] There are two heating core pressing plates 46, and the two heating core pressing plates 46 are symmetrically installed along the central axis of the middle of the aluminum casting runner 41. The ceramic heating pipe 45 is installed vertically. There are four ceramic heating pipes 45, and the four ceramic heating pipes 45 are evenly distributed at the bottom of the inner cavity of the aluminum casting runner 41. The ceramic heating pipe 45 passes through the center of the heating core pressing plate 46, and the ceramic heating pipe 45 is fixed by the heating core pressing plate 46, making the ceramic heating pipe 45 firmly fixed and not prone to looseness and skew. And the ceramic heating pipe 45 heats the fluid in the inner cavity of the aluminum casting runner 41, so that the temperature of the fluid in the inner cavity of the aluminum casting runner 41 rises after being heated. And there are four ceramic heating pipes 45, and the four ceramic heating pipes 45 are evenly distributed at the bottom of the inner cavity of the aluminum casting runner 41, promoting the uniform heating of the fluid in the inner cavity of the aluminum casting runner 41.

[0046] The second embodiment, on the basis of the first embodiment, please refer to Figures 1 to 7 as shown:

[0047] A flow guiding mechanism 5 is installed at the middle of the inner cavity of the cast aluminum runner 41. The flow guiding mechanism 5 includes a middle flat plate 51. One end of the surface of the middle flat plate 51 is fixedly connected to the middle of the inner wall of the cast aluminum runner 41. A single-sided bent plate 53 is fixedly connected to the side of the inner wall of the cast aluminum runner 41. A double-sided bent plate 52 is fixedly connected to the inner wall of the cast aluminum runner 41, and the double-sided bent plate 52 is installed between the middle flat plate 51 and the single-sided bent plate 53. An anti-backflow component 54 is installed between the surface of the middle flat plate 51 and the surface of the double-sided bent plate 52. The end cover 44 is used to install on the top of the cast aluminum runner 41, so that the inner cavity of the cast aluminum runner 41 forms a sealed space, and the fluid enters the inside of the cast aluminum runner 41 from the liquid inlet pipe 42. The fluid will be guided by the single-sided bent plate 53, so that the fluid fully contacts the two ceramic heating tubes 45 on the side of the inner cavity of the cast aluminum runner 41, and then the preliminary heating can be carried out. As the flow path formed by the double-sided bent plate 52, the middle flat plate 51 and the single-sided bent plate 53 is in a curve S shape, the flow of the fluid in the cast aluminum runner 41 can be increased. At the same time, before the fluid flows out from the liquid outlet pipe 43, it will be heated by the two ceramic heating tubes 45 on the other side again, and the temperature rises quickly.

[0048] There are two double-sided bent plates 52, and the two double-sided bent plates 52 are symmetrically installed along the middle flat plate 51. There are two single-sided bent plates 53, and the two single-sided bent plates 53 are symmetrically installed along the middle flat plate 51.

[0049] The anti-backflow component 54 includes a square frame body 541. The square frame body 541 is fixedly connected between the surface of the middle flat plate 51 and the surface of the double-sided bent plate 52. A wedge-shaped plug 542 is installed at the liquid outlet end of the surface of the square frame body 541. A first elastic sheet 543 is fixedly connected between the surface of the wedge-shaped plug 542 and the surface of the middle flat plate 51. A second elastic sheet 544 is fixedly connected between the surface of the wedge-shaped plug 542 and the surface of the double-sided bent plate 52. As the fluid flows in the flow path formed by the double-sided bent plate 52, the middle flat plate 51 and the single-sided bent plate 53, under the action of the fluid pressure, the fluid exerts a driving force on the wedge-shaped plug 542, so that the wedge-shaped plug 542 moves outward and compresses the first elastic sheet 543 and the second elastic sheet 544, so that the channel inside the square frame body 541 is opened, and the fluid flows smoothly. When the fluid is about to flow reversely, the driving force of the fluid on the wedge-shaped plug 542 disappears, and under the elastic force of the first elastic sheet 543 and the second elastic sheet 544, the wedge-shaped plug 542 timely blocks the channel of the square frame body 541.

[0050] The surface of the wedge-shaped plug 542 fits with the inner wall of the liquid outlet end of the square frame body 541. Both the first elastic sheet 543 and the second elastic sheet 544 are arc-shaped, and the first elastic sheet 543 and the second elastic sheet 544 are installed at the same height.

[0051] The third embodiment is based on the first and second embodiments. Please refer to Figures 1 to 9 as shown in

[0052] An anti-leakage mechanism 6 is installed at one end of the liquid inlet pipe 42 far from the cast aluminum runner 41 and one end of the liquid outlet pipe 43 far from the cast aluminum runner 41. The anti-leakage mechanism 6 includes a connecting ring 61, an annular groove 62 and a conical connecting head 63. The connecting ring 61 is threadedly installed with the liquid outlet pipe 43 through a thread groove. The annular groove 62 is opened at the conical surface of the liquid outlet pipe 43. A right-angled tooth 64 is fixedly connected to the outer circular surface of the connecting ring 61. An annular clamping groove 65 is opened at the side of the outer circular surface of the conical connecting head 63. The conical connecting head 63 is slidably installed with the right-angled tooth 64 through the annular clamping groove 65. A sealing ring 66 is fixedly connected to the conical surface of the inner cavity of the conical connecting head 63. By using the right-angled tooth 64 protruding from the outer circular surface of the connecting ring 61, it is convenient to twist the connecting ring 61 by the right-angled tooth 64, so that the connecting ring 61 is fixedly connected to the liquid inlet pipe 42 and the liquid outlet pipe 43 by threads. Then, through the pulling force of the right-angled tooth 64 on the conical connecting head 63, the conical connecting head 63 is sleeved on the ends of the liquid inlet pipe 42 and the liquid outlet pipe 43, and the inner side surface of the sealing ring 66 is embedded into the inside of the annular clamping groove 65, and the conical connecting head 63 squeezes the sealing ring 66, so that the sealing ring 66 fills the gap between the inner wall of the conical connecting head 63 and the ends of the liquid inlet pipe 42 and the liquid outlet pipe 43, and thus sealing can be achieved.

[0053] The connecting ring 61, the annular groove 62 and the liquid outlet pipe 43 are installed at the same height. There are two right-angled teeth 64, and the two right-angled teeth 64 are symmetrically installed along the central axis of the middle of the connecting ring 61.

[0054] When the connecting ring 61 drives the right-angled tooth 64 to rotate, and the conical connecting head 63 is slidably installed with the right-angled tooth 64 through the annular clamping groove 65, the right-angled tooth 64 will only generate a pulling force on the conical connecting head 63, and there will be no torsional force in the circumferential direction, which promotes the conical connecting head 63 to squeeze the sealing ring 66, so that the sealing ring 66 will not be skewed or displaced.

[0055] The right-angled end of the right-angled tooth 64 fits with the inner wall of the annular clamping groove 65. The center of the sealing ring 66 coincides with the axis of the middle of the conical connecting head 63. The sealing ring 66 and the annular groove 62 are installed at the same height.

[0056] During use, first, the right-angled teeth 64 protrude from the outer circumferential surface of the connecting ring 61, facilitating the rotation of the connecting ring 61 by means of the right-angled teeth 64. When the connecting ring 61 drives the right-angled teeth 64 to rotate, and the conical connector 63 is slidably mounted on the right-angled end of the right-angled teeth 64 through the annular slot 65, the right-angled teeth 64 will only exert a pulling force on the conical connector 63, without any torsional force in the circumferential direction, promoting the extrusion of the sealing ring 66 by the conical connector 63, so that the sealing ring 66 will not be skewed or displaced;

[0057] Moreover, by threadedly connecting and fixing the connecting ring 61 with the liquid inlet pipe 42 and the liquid outlet pipe 43, the pulling force of the conical connector 63 by the right-angled teeth 64 can make the conical connector 63 sleeved on the ends of the liquid inlet pipe 42 and the liquid outlet pipe 43. And the inner side surface of the sealing ring 66 is embedded into the internal part of the annular slot 65, and the sealing ring 66 is extruded by the conical connector 63, so that the sealing ring 66 fills the gap between the inner wall of the conical connector 63 and the ends of the liquid inlet pipe 42 and the liquid outlet pipe 43, and thus sealing can be achieved;

[0058] At the same time, the integration of the heating mechanism 4 and the compressor pump body 1 integrates the heat exchange flow path and the heating component onto the compressor pump body 1, and the controller 2 is integrated with the compressor pump body 1, reducing the use of control chips and also reducing the number of high and low voltage contact parts;

[0059] The heating mechanism 4 is directly electrically connected to the compressor pump body 1 through the terminal block to realize the function of controlling the heating mechanism 4 and the compressor pump body 1 together;

[0060] And the end cover 44 is installed on the top of the cast aluminum flow path 41, making the inner cavity of the cast aluminum flow path 41 form a sealed space. And the fluid enters the inside of the cast aluminum flow path 41 from the liquid inlet pipe 42, and the ceramic heating tube 45 is fixed by the heating core pressing plate 46, so that the ceramic heating tube 45 is firmly fixed and not prone to looseness and skewness. The fluid will be guided by the single-sided bending plate 53, so that the fluid fully contacts the two ceramic heating tubes 45 on the side of the inner cavity of the cast aluminum flow path 41, and thus preliminary heating can be carried out;

[0061] Moreover, since the flow path composed of the double-sided bending plate 52, the middle plane plate 51 and the single-sided bending plate 53 is in a curve S shape, the flow of the fluid in the cast aluminum flow path 41 can be increased. At the same time, before the fluid flows out from the liquid outlet pipe 43, it will be heated again by the two ceramic heating tubes 45 on the other side, with a fast temperature rise, promoting the uniform heating of the fluid in the inner cavity of the cast aluminum flow path 41;

[0062] Moreover, as the fluid flows in the flow channel formed by the bilateral bent plate 52, the middle flat plate 51, and the unilateral bent plate 53, under the action of the fluid pressure, the fluid exerts a driving force on the wedge plug 542, causing the wedge plug 542 to move outward and compress the first elastic sheet 543 and the second elastic sheet 544. As a result, the channel inside the square frame 541 is opened, enabling the fluid to flow smoothly. When the fluid is about to flow in the reverse direction, the driving force of the fluid on the wedge plug 542 disappears, and under the elastic force of the first elastic sheet 543 and the second elastic sheet 544, the wedge plug 542 timely blocks the channel of the square frame 541.

[0063] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
