Abstract

Abstract A system for temperature control of an electronic component includes a heat plate (10) supporting the component (18); a heat plate temperature sensor (20), a fan (14) capable of providing air for cooling the heat plate; and a fan control (22) for using the heat plate temperature to control the operation of the fan to provide a substantially constant heat plate temperature. The system can further include a heat pipe assembly (12) having fins and coupled to the heat plate with the fan capable of providing air to the fins. The heat pipe assembly can include at least two heat pipes each having first ends coupled to the heat plate and second ends situated in a condensation section where at least one of the heat pipes has a different working fluid than an other. A switch temperature or load current sensor can be coupled to the heat plate and supply data to a switch controller for receiving the switch temperature, determining whether the temperature or load current has changed, and adjusting a switching frequency of the at least one electronic switch device in response to any change of the switch temperature. A bus layer can be situated adjacent the component and selectively coated with an insulating material and studs can mechanically and electrically coupling the bus layer and a printed circuit board to the component. An insulating shield can be situated between the bus layer and the printed circuit board with the studs.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 77 words
A system for temperature control of at least one electronic component, the system comprising: a heat plate supporting the at least one electronic component; a heat plate temperature sensor for obtaining a heat plate temperature; a fan capable of providing air for cooling the heat plate and the at least one electric component; a fan control for using the heat plate temperature to control the operation of the fan to provide a substantially constant heat plate temperature.
Claim 2
Dependent Claim 24 words
The system of claim 1, wherein the fan control includes means for adjusting the fan speed to compensate for changes in heat plate temperature.
Claim 3
Dependent Claim 30 words
The system of claim 1, further including a heat pipe assembly having fins, the heat pipe coupled to the heat plate, the fan capable of providing air to the fins.
Claim 4
Independent Claim 125 words
A system for temperature control of at least one electronic component, the system comprising: a heat plate supporting the at least one electronic component; and a heat pipe assembly including at least two heat pipes each having first and second ends with the first ends coupled to the heat plate, a condensation section, the second ends of the at least two heat pipes being situated in the condensation section, at least one of the at least two heat pipes being bent so as to be situated on a different plane than an other of the at least two heat pipes, at least one of the at least two heat pipes having a different working fluid than an other of the at least two heat pipes.
Claim 5
Dependent Claim 40 words
The system of claim 4, wherein the first one of the at least two heat pipes has a working fluid with a lower freezing point than a working fluid of the second one of the at least two heat pipes.
