Definitions
- the present invention relates in general to a spray tempering arrangement capable of both cooling and heating electronic components.
- a preferred method of liquid cooling is the so-called two-phase cooling.
- a two-phase cooling occurs when the coolant changes from one phase to another, e.g. from liquid to vapor. Due to the increased energy required for a phase change, two-phase cooling systems often offers the ability to provide more compact and higher performance cooling systems than single-phase systems.
- a single-phase cooling occurs when the coolant remains in the same phase during the whole cooling process, e.g. remains liquefied or vaporized during the whole cooling process.
- An exemplary two-phase cooling method is spray cooling.
- Common spray cooling system uses at least one pump for supplying fluid to at least one nozzle that transforms the fluid into droplets. These droplets impinge on the surface of the component to be cooled so as to typically create a thin liquid film. Energy is transferred from the surface of the component to the thin liquid film as the liquid evaporates. Since the fluid may be dispensed at or near its saturation point, the absorbed heat causes the thin film to turn to vapor. This vapor is then condensed, often by means of a heat exchanger, or condenser, and returned to a reservoir and/or the pump.
- the present invention represents an improvement compared to prior art by providing a spray tempering arrangement capable of both heating and cooling electronic components.
- a temperature managing arrangement comprising a reservoir arranged to operatively accumulate a tempering liquid, a pressurizing device arranged to operatively pressurise the tempering liquid and at least one spray module arranged to operatively receive the pressurized liquid and which comprises at least one spraying device, e.g. a nozzle, arranged to operatively spray the liquid on at least one electronic component so as to create a thermal coupling between the sprayed liquid and the component.
- the temperature managing arrangement comprises a heat remover arranged to operatively cool the tempering liquid after spraying when thermal energy is to be removed from said component ( 224 ).
- the tempering liquid becomes at least one of a liquid, a vapor or a mist after spraying, e.g. due to sprinkling in the spraying device or heating by the electric component.
- the tempering managing arrangement comprises a heating device arranged to operatively heat the tempering liquid before spraying when thermal energy is to be provided to said component.
- the tempering liquid is in liquid form before spraying.
- the thermal energy is removed from said component according to a two-phase cooling.
- the tempering liquid is preferably an electrically insulating fluid.
- the heating device is preferably arranged to operatively heat the tempering liquid to a temperature near or above the middle of the temperature range specified by the manufacturer for the electronic component to be provided with thermal energy.
- Said at least one spraying device can be arranged to operatively spray the tempering liquid on a first electronic component in the form of a cooling flange or a cooling surface thermally coupled to a second electronic component to be heated or cooled by the liquid.
- Said at least one spraying device can be arranged to operatively spray the tempering liquid on an electronic component in the form of a circuit board, or a rack provided with a plurality of circuit boards.
- Said at least one spraying device can be arranged to operatively spray the tempering liquid on a first electronic component in the form of a cooling flange or a cooling surface thermally coupled to a second electronic to be heated or cooled by the liquid.
- Said spray module can comprise at least two types of spraying devices, wherein a first spraying device type is arranged to be operatively used when the temperature managing arrangement operates as a cooling arrangement and a second spraying device type is arranged to be operatively used when the temperature managing arrangement operates as a heating system.
- the present invention represents an improvement compared to prior art by providing a method for temperature managing using said temperature managing arrangement, which method comprises the steps of accumulating a tempering liquid ( 242 ) in a reservoir ( 140 , 240 ); pressurizing the tempering liquid ( 242 ) by means of a pressurizing device ( 110 , 210 ); providing the pressurized liquid ( 242 ) to at least one spray module ( 120 , 220 ) comprising at least one spraying device ( 222 ) arranged to spray the liquid ( 242 ) on at least one electronic component ( 224 ) so as to create a thermal coupling between the sprayed liquid ( 242 ) and the component ( 224 ); cooling the tempering liquid ( 242 ), being in at least one of a liquid, a vapor or a mist form after spraying, by means of a heat remover ( 130 , 230 ) when thermal energy is to be removed from said component ( 224 ); and heating the tempering liquid ( 242 ) by means of
- the tempering liquid is preferably heated to a temperature near or above the middle of the temperature range specified by the manufacturer for the electronic component to be provided with thermal energy.
- At least one spraying device is spraying the tempering liquid on a first electronic component in the form of a cooling flange or a cooling surface thermally coupled to a second electronic component to be heated or cooled by the liquid.
