Method and system for using the waste heat of a computer system
InactiveUS20090114370A1Improve efficiencyUse waste heatDigital data processing detailsAir heatersComputerized systemWaste heat
A method for using the waste heat of a computer system with a plurality of processors comprises the following steps. Jobs in the computer system are distributed to the processors in such a way that processors of a first group of processors are operated with a high processor load and processors of a second group of processors are operated with only a minimal processor load. In another method, waste heat is dissipated from the processors by a cooling device, wherein the waste heat dissipated from the processors is regulated in such a way that the processor assumes a temperature that is greater than a given minimum temperature. In both cases, the waste heat of the processors is transferred to a device for using the waste heat.

Heating control system for vehicle
InactiveCN1950223AImprove economyIncrease temperatureHybrid vehiclesAir-treating devicesThermal energyEngine efficiency
A hybrid vehicle can be driven using both of respective driving forces from an engine and a motor. A heating mechanism of an air conditioning apparatus uses thermal energy from cooling water of the engine to heat the interior of a passenger compartment. An ECU takes into consideration engine efficiency from the standpoint of fuel economy enhancement to primarily determine the driving force share ratio between the engine and the motor. Further, the ECU calculates a preset temperature corresponding to a cooling water temperature necessary for desired heating as well as a control target temperature in which the preset temperature is reflected, and corrects the primarily determined driving force share ratio to increase the share of the driving force of the engine by an amount according to a deviation between the cooling water temperature measured by a water temperature sensor and the control target temperature. Heating performance can thus be ensured promptly without deterioration of fuel economy.

A fluid line is connected thermally to at least one component of the electric machine (14,16) to supply a cooling fluid (36) to the electric machine (14, 16) and to cool the at least one component. A fan (30, 32) is designed to supply cooling air (42) to the electric machine for cooling the electric machine (14, 16), and a control unit (34) controls the fan (30, 32). The control unit (34) controls the fan arrangement (30, 32) and the cooling air supply depending on a speed (n) and / or a torque (M) of the electric machine (14, 16).
