Definitions
- the invention relates to an electronic device with a
- An ion cooling system for cooling system components of the device and a method for monitoring an electrostatic charge of components of the electronic device caused by an ion cooling system.
- the cooling of system components plays an important role in electronic devices such as a computer system.
- the cooling prevents overheating of the components and thus ensures the functionality of the individual components and uninterrupted operation of the device.
- cooling of the system components is accomplished by a cooling system of one or more ventilation fans.
- the fans create an airflow that cools the components of the unit and expels the heated air out of the unit.
- ion cooling in electronic devices is known.
- an ion-cooling system is usually integrated into the system in which the conventional fans are replaced by an element that generates an air flow.
- the cooling system consists, for example, of one or more ion coolers which have two grounded grids between which is an array of wires that are under positive and negative high voltage. At the electrodes are surrounded by the high voltage applied surrounding air molecules. The positively charged ions move in the voltage gradient to the negatively charged cathodes and collide on the way there with other air molecules. This creates an ion current. As a result of the collisions with neutral air molecules, this ion current generates an air flow on the surface of the components of the electronic device, thereby cooling the components.
- the grounded grids are designed to discharge the generated ions as completely as possible and thereby largely free the air from ions again.
- the disadvantage of cooling an electronic device by means of an ion-cooling system is that, despite the discharge of the ions through the grounded grids, the air stream cooling the components may have a certain degree of ionization, which may charge and damage the electronic components.
- the air stream cooling the components may have a certain degree of ionization, which may charge and damage the electronic components.
- a not optimally functioning or set ion cooling can lead to an excessive ionization of the air flow, which can have a strong negative impact on a trouble-free operation of the electronic device.
- the effect of the ionized air flow on the components may also depend on the environmental characteristics of the device, such as humidity or dust concentration in the air within the device. Due to the caused by the ionization of the air flow electrostatic charge of the components can lead to critical voltages, which can lead to the failure of individual components or the device itself.
- the object of the invention is therefore to describe an electronic device with an ion-cooling system, in which a generated by the ion cooling electrostatic charge of the components of the device can be controlled.
- an electronic device of the type mentioned which is characterized in that at least one arrangement is incorporated in the device, through which the ionization of the air flow can be determined.
- the degree of ionization of the cooling air flow and its effects on the components located in the air flow of the device - ie their electrostatic charge - controlled on the other hand the functioning of the entire ion cooling system tested without that electronic device must be switched off or opened or even an expansion of the cooling system is required.
- a measurement of the charge transferred by the ionization to at least one electrode is provided for determining the ionization of the air flow.
- a further embodiment of the invention provides for the determination of the ionization, a measurement of the effluent from the at least one electrode current.
- a preferred embodiment provides that the at least one electrode is a heat sink of a system component of the device.
- a further preferred embodiment of the invention provides that the at least one electrode is a conductive surface of a system component of the electronic device located in the ionized air flow.
- the at least one electrode is a dummy component which is introduced into the device and which is in the ionized air stream.
- a preferred embodiment of the invention provides that the at least one arrangement for determining the ionization of the air flow has a device with which the current flowing from the at least one electrode can be determined and that the at least one arrangement connects the at least one electrode to a ground potential ,
- the at least one arrangement for determining the ionization additionally has a switching element with which the connection between the at least one electrode and the ground potential can be established or interrupted. This can also be a build up over a longer period of electrostatic
- Charging the at least one electrode for example for test purposes, can be achieved. It is also possible despite generating only a small ionization of the air flow, a detectable signal.
- FIG. 1 shows a schematic representation of a computer system with a power supply, a CPU, drives, a hard disk, an ion cooling system and system components provided in the air flow of the ion cooling, as well as arrangements for measuring the ionization of the air flow.
- FIG. 2 shows a schematic representation of the computer system from FIG. 1 with an ion cooling system according to the prior art
- FIG. 3 shows a flow chart for a method for monitoring the electrostatic charging of a component of an electronic device located in the ionized air flow.
- FIG. 2 shows an arrangement of a computer system 1 which has a power supply unit 2, a CPU 3, two drives 4 and a hard disk 5. Furthermore, this includes
- Computer system 1 a system component 6 and an ion cooling system 7 for cooling components of the computer system 1 by ion cooling according to the prior art, as shown in FIG a computer system 1, for example a desktop personal computer (PC), a notebook or a server, is usually realized.
- the ion cooling creates an air stream 8 through which the components of the computer system 1 located within the air stream 8, such as in this embodiment the CPU 3 and the system component 6, are cooled on the surface.
- a malfunction of the cooling system 7 can (in addition to the unavoidable Restiontechnik the air flow 8) lead to excessive ionization of the air stream 8. This has the consequence that the components located in the air stream 8, in this case the CPU 3 or the component 6, unnoticed by the ionized air stream 8 to charge to a critical value for the computer system 1, resulting in a
- FIG. 1 shows the computer system 1 shown in FIG. 2 with the system components (2-6) described above as well as the ion cooling system 7 and the air flow 8 generated by the ion cooling.
- the computer system 1 further includes two assemblies 9.
- the assembly 9 connects an electrode to a ground potential 11 and includes, for example, a device 12 for measuring the voltage dropped across a resistor 13, which is proportional to the current flowing from the electrode.
- a comparison Evaluation be included in the arrangement 9.
- the voltage values could be read in via the comparison evaluation circuit, converted into current values and forwarded to a mainboard for further processing by software of the computer system 1.
- the arrangement 9 is set up to measure the charge transferred by the ionized air stream 8 to at least one electrode and thus to determine the ionization of the air stream 8. It is attached to it in the air stream 8 located electrodes.
- a graphics card or a sound card - attached conductive surface for example, a heat sink of the system component 6) and an additional introduced in the air stream 8 component 10.
- a on or in the power supply 2 attached conductive surface as an electrode for monitoring the charging of the power supply 2 in its ion cooling conceivable.
- the heat sink is usually made of a thermally conductive metal, such as aluminum or copper, and serves for improving the heat dissipation of heat-generating components, as in this case the system component 6.
- the heat sink may be attached by means of screws or clamps to the system component 6, or else be glued to the system component 6.
- the component 10 may be a conductive, ungrounded surface.
- This surface may be shaped in shape as another system component (dummy component), which makes measurements of the electrostatic charge of this electrode more realistic for an evaluation of the charging of the system components of the computer system 1.
- This dummy component is not important to the operation of computer system 1, but provides meaningful measurements of the ionization of the airflow 8 and the size of the generated electrostatic charge.
- any further heat sink of system components of the computer system 1 can continue to serve, in particular, the CPU heatsink can be used.
- a measurement of the charge transferred to the electrode can also be carried out directly in order to determine the ionization of the air stream 8. This can for example be done by an arrangement that includes a capacitor. By transferring the charge of the electrode to the capacitor and then measuring the voltage drop across the capacitor, the charge can be determined directly, given the known capacitance of the capacitor.
- the arrangement 9 can, for example, as shown in this embodiment - also contain a switching element, through which the connection of the component 10 can be made or interrupted at the ground potential.
- the switching element in arrangement 9 may include transistors or a thyristor arrangement.
- a circuit by means of a relay is conceivable.
- the switching element is - as shown schematically in Figure 1 - controlled in this embodiment of the CPU 3 of the computer system 1, but it is also conceivable that the switching element is controlled internally by a timer additionally contained in the assembly 9.
- This period may be determined by a predetermined time, which should be adapted to the operation of the cooling system 7 and the degree of ionization of the air stream 8.
- a timer additionally contained in the arrangement 9 can be used, after which, for example, the switching element is switched, thus establishing the connection of the electrode to the ground potential 11 and then measuring the voltage dropping across the resistor 13. If the connection is interrupted again, the timer is reset and restarted. This makes it possible to check the ionization at regular, predetermined intervals.
- FIG. 3 shows a flow chart for a method for
- Step S1 designates the electrostatic charge caused by the ionized air flow 8 of the component of the device.
- the component can, for example, a subsequently introduced into the device Electrode, which is designed like an electronic component of the device. Also, a conductive surface (such as a heat sink) of each other in the device and present in the air stream 8 system component is conceivable as an electrode.
- the component in this embodiment is connected to a device 9 which contains a switching element, so that a connection between the component of the device and a ground potential 11 can be interrupted or produced. With only slight ionization of the air stream 8, the connection is interrupted by the switching element, and thus causes a measurable electrostatic charge, which can be determined in a next step.
- step S2 the connection between the component and the ground potential 11 is established by the switching element in arrangement 9.
- the compound can be prepared at predetermined intervals - for example, by a timer contained in the arrangement 9 - depending on the strength of the ionization of the air stream 8, on the one hand to exclude an overcharge of the component, on the other hand, however, a measurable signal by a building up over a certain period to generate electrostatic charge of the component.
- step S3 a measurement of the electrostatic charge of the component is performed. This can be done by determining the current flowing out of the component by means of a device 12 contained in an arrangement 9
- step S4 the determined value is compared with a predetermined reference value, which should be uncritical for the components or the device.
- Step S5 includes an inquiry as to whether the value obtained in step S3 is smaller than the reference value. If so, then the connection between the component and the ground potential 11 is then interrupted again (step S6) and a recharging of the component by the ionized air stream 8 takes place (step S1).
- step S7a If the value for the electrostatic charging of the component determined in step S3 is greater than the reference value, a warning signal is output in step S7a.
- step S7b the ion cooling of the device is turned off and then, in step S7c, a further redundant conventional cooling by fans is switched on in the device. Switching must be done so fast that no overheating of the components of the device can occur due to interruption of the cooling.
- step S7a it is also possible to output only a warning signal (step S7a) without having to additionally switch off the ion cooling system 7 (step S7b) or switch to conventional cooling mode (step S7c). Even a complete shutdown of the device when the reference value is exceeded is conceivable.
- the ionization of the air stream 8 (even in the case of only low ionization) continuously monitored, thus overloading the components of the Device can be prevented. This ensures uninterrupted operation of components and equipment.
