Patent number: 8559175Abstract: A semiconductor cooling device for transferring heat from a semiconductor die (111). The semiconductor cooling device includes a heat dissipator (112) that may be thermally coupled to a semiconductor module (111) to be cooled for dissipating heat from the semiconductor die (111); a housing (150) in or on which the semiconductor die (111) is mounted; a fluid flow passage (153) for providing a forced fluid flow within the housing (150); and a fluid path (155) arranged to guide the forced fluid flow in a first direction between the fluid flow passage (153) and the heat dissipator (112) and further arranged to guide the fluid flow along the heat dissipator (112) in a second direction different to the first direction. In a particular embodiment, the semiconductor cooling device is used to dissipate heat from an array of LEDs.Type: GrantFiled: July 16, 2009Date of Patent: October 15, 2013Assignee: Koninlijke Philips N.V.Inventors: Bart-Hendrik Huisman, Nicolas Mignot, Hendrik Jan Eggink, Clemens Johannes Maria Lasance

Patent number: 8529105Abstract: This invention relates to thermal management for removing heat generated by a heat source (110). This is done by a combination of a heat conducting member (120), which is thermally connected to the heat source in one end and to a remotely arranged heat sink (130) in the opposite end, and a synthetic jet actuator (140). The synthetic jet actuator is arranged to provide active cooling directly onto the heat source by generating and directing an air flow towards the heat source. The synthetic jet actuator comprises a resonator cavity housing (150) and an oscillating member (160). The oscillator member is arranged at least partly inside said resonator cavity. The combination of the heat conducting member and the synthetic jet actuator provides a highly efficient cooling.Type: GrantFiled: June 25, 2009Date of Patent: September 10, 2013Assignee: Koninklijke Philips N.V.Inventors: Georges Marie Calon, Ronaldus Maria Aarts, Peter Alexander Wachters, Antonius Adrianus Maria Marinus, Reinhold Elferich, Hugo Johan Cornelissen, Clemens Johannes Maria Lasance

Patent number: 8390184Abstract: A system comprises a light source (42) and an electrode device (1). The light source comprises a base (46) with a base surface on which at least two contact elements (47, 48, 54) are provided. The electrode device has at least two electrodes (23, 24, 31, 32) in mutually stacked positions, which electrodes are preferably made of a permanent magnetic, ferromagnet or electro-magnetic material and have a different polarity during operation. The system further comprises at least one electrode comprising a layer of auto-closing material. This ensures that the system can maintain a satisfactory, reliable electric contact between the electrodes and the contact elements, and, after removal of the light source, gives the system a more aesthetic appearance because damages are practically invisible.Type: GrantFiled: February 9, 2009Date of Patent: March 5, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Robert Pet, Clemens Johannes Maria Lasance

Patent number: 8218318Abstract: A cooling device (1) using pulsating fluid for cooling of an object, comprising: a transducer (2) having a membrane adapted to generate pressure waves at a working frequency (fw), and a cavity (4) enclosing a first side of the membrane. The cavity (4) has at least one opening (5) adapted to emit a pulsating net output fluid flow towards the object, wherein the opening (5) is in communication with a second side of the membrane. The cavity (4) is sufficiently small to prevent fluid in the cavity (4) from acting as a spring in a resonating mass-spring system in the working range. This is advantageous as a volume velocity (u1) at the opening is essentially equal to a volume velocity (u1?) at the second side of the membrane, apart from a minus sign. Thus, at the working frequency the pulsating net output fluid can be largely cancelled due to the counter phase with the pressure waves on the second side of the membrane resulting in a close to zero far-field volume velocity.Type: GrantFiled: November 26, 2008Date of Patent: July 10, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Ronaldus Maria Aarts, Clemens Johannes Maria Lasance, Joris Adelbert Maria Nieuwendijk, Okke Ouweltjes

Publication number: 20100165615Abstract: An illumination device (1) comprising: at least one light emitting device (5); and a suspension structure (2), suspending the at least one light emitting device (5) in a desired position. Further, the illumination device (1) has a transducer (6), adapted to generate pressure waves at a drive frequency; wherein the suspension structure (2) is utilized as a flow guiding structure (7), having a first end adapted to receive the pressure waves from the transducer, and a second end adapted to generate a pulsating net output flow towards the at least one light emitting device (5), thereby cooling the at least one light emitting device (5). By utilizing the suspension structure itself as flow guiding structure cooling can be integrated in a cost efficient way. Further, no additional space is required to accommodate the flow guiding structure.Type: ApplicationFiled: June 9, 2008Publication date: July 1, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Ronaldus Maria Aarts, Clemens Johannes Maria Lasance, Joris Adelbert Maria Nieuwendijk, Okke Ouweltjes

Publication number: 20090168343Abstract: A cooling device using pulsating fluid for cooling of an object (8), comprising a transducer (2) adapted to generate pressure waves at a drive frequency, a tube (3), having a first end adapted to receive said pressure waves from the transducer, and a second end (7) adapted to generate a pulsating net output flow towards the object (8). Compared to a Helmholtz resonator, where the length of the tube is short compared to the wavelength, the length (L) of the tube according to the present invention is greater than ?/10, which has been found to be sufficiently long to avoid Helmholtz resonance. Instead, the tube acts as a transmission line, that applies a velocity gain to the pulsating flow.Type: ApplicationFiled: March 14, 2007Publication date: July 2, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Ronaldus Maria Aarts, Clemens Johannes Maria Lasance
