1. Field of the Invention
The present invention relates generally to systems of transportation of fluids, Particularly, the present invention relates to the design of valves of streams of fluid: for closing and/or opening a channel, for switching flow of fluid from one channel to another one, for allowing fluid to flow in two directions, etc.
2. Description of the Related Art
The last decade of development of the integrated circuits, especially CPUs (central processing units) and GPUs (graphic processing units), evidently demonstrated that we have reached the limits of frequencies, at which the traditional air cooling of working processors can provide reliable evacuation of the generated parasitic heat in order to keep said processors within the safe domain of their temperatures. It became clear that future progress in the increasing of working frequencies of processors is possible only with implementation of the convective cooling of processors by the circulating fluid coolant, particularly water. The water cooling of servers already became a routine practice in the big Data Centers. Individual enthusiasts are using self-made convective water cooling systems in their PCs, reaching frequencies 2-3 times higher, than CPUs and GPUs manufacturers' recommended values. Industry offers some convective cooling systems for Desktops, but all of them are essentially oversized, overweight, expensive and inefficient. There are no solutions for Laptops on the current Market.
All implemented solutions for water cooling of the integrated circuits actually are employing well known and very traditional methods and systems of the domestic plumbing and heating and cooling, while the cooling of PC is much more complex problem and it requires much more sophisticated and flexible approach.
Particularly, an efficient multi-modular cooling system requires implementation of certain valves of streams of a fluid coolant in order to provide optimal cooling in different regimes of operation of the chilled elements. Limited dimensions of laptops essentially restrict the implementation of valves that are currently offered on the market: the invention of new designs of valves is highly demanded.
There is a huge variety of valves of fluid streams on the contemporary market with the same functionality and many different manners of operation: manual, pneumatic, by electric motors, etc., but none of them can satisfy the most important requirement that is crucial for the implementation in laptops: to have overall thickness of about several millimeters, be driven by electricity, and have price within the range of a few dollars.
It is an object of the present invention to teach the method and a system of switching flows of a fluid in channels and between channels, wherein designed valves
Advantages and features of the present invention are better understood with the reference to the following more detailed description and claims taken in conjunction with accompanying drawings, in which like elements are identified with like symbols.
The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within the Figures.
A preferred embodiment's of the planar valve and its main functionality is to provide a reliable switching of the stream of fluid between different channels by switching the polarity of the electric current on its driver.
The drawing of the base [001] is shown in
A variety of valves can be created by placing inside said base different pistons [002] with appropriate cores [003].
The drawing of the core for straight valve is shown in
The entire set—the base with the piston and core inside it—is placed on the top of the driver box [012] on the one end of said box. On the other end of the driver box [012] the matching turning disk [005] is attached on the proper pedestal [011]. The rod loop [006] is put on both turning disks [004] and [005]. This rod loop is attached to both turning disks in points [010] that are marking the maximal distance between said disks. Such setting provides a signature feature of this pare of turning disks: when one disk turns 90 degrees, the second one also turns 90 degrees in the same directions even if there is no friction between rod and disks.
The one half of said rod loop goes through two complementary coils [007] and has an attached permanent magnet [008]. Complementariness of coils means that, being fed from the same source of a direct electric current, which is delivered by en external source through electrodes [009], they produce magnetic fields that are in opposite directions to each other.
In just said conditions, permanent magnet [008] has only two points of equilibrium between said coils: near by each of coils; at one polarity of voltage on electrodes [009] the equilibrium of permanent magnet [008] is near by the right coil, and at opposite polarity—near by the left coil; consequently, at switching of polarity of the direct voltage on electrodes [009], permanent magnet [008] will be repulsed from its position near by one coil to the position near by complementary coil, and otherwise. The distance between turning disks [004] and [005], their radiuses, and the length of permanent magnet [008] should be chosen in such manner to provide the following signature condition of the present invention: relocation of permanent magnet [008] from of one its equilibrium position near by one coil to its other equilibrium position near by the complementary coil should cause the turning disks [004] and [005] turn exactly on 90 degrees in the same direction.
It is anticipated that all disclosed features are provided due to the all properly designed disclosed parts of the present invention. Then the regulated channels should be reliably attached to the holes in the sides of base of the used valve (manners of such attachments are not subjects of the present invention). The operations of such arranged implementations are illustrated schematically in FIG. 8—for a straight planar valve, in FIG. 9—for the planar T-valve, and in FIG. 10—for a dual-valve. As one can see, the switching of streams of a fluid between regulated external channels that are attached to holes in the base of used valve goes by a simple application of a working direct voltage of a given polarity to electrodes [009] of the used valve.
