Technical field
The utility model relates to electronic equipment dissipating heat technical field, especially relates to the stepless cooling and radiation device of a kind of energy-saving power amplifier temperature control.
Background technology
Power amplifier is the visual plant in sound system, and along with scientific and technical development and people are to acoustic pursuit, the power of power amplifier is increasing, and caloric value is also increasing, therefore requires also more and more higher to heat radiation.
The cooling system of current traditional power amplifier mainly adopts and installs fan additional and carry out air blast cooling heat radiation or utilize natural convection air this two kinds of modes of dispelling the heat.Because natural convection air heat radiation is slower, therefore high-power power amplifier generally adopts the air-cooled radiating mode of fan to dispel the heat.In the wind-cooling heat dissipating system of traditional power amplifier, fan adopts constant-speed operation heat radiation, and power amplifier one is started shooting, and fan is to carry out at a high speed constant speed running, until shutdown.Because temperature in just start of power amplifier or running changes, only need to adopt fan to run up in exceeding certain index to carry out forced heat radiation temperature is higher, and it is not high in temperature, even very low time, can adopt more slow-revving fan even to stop fan forced heat radiation system and adopt natural wind cooling system can reach radiating effect.Therefore, traditional constant speed fans in operation wind-cooling heat dissipating system, by increasing the overall energy consumption of power amplifier, does not meet product design of energy saving and environmental protection theory.
Summary of the invention
The purpose of this utility model is to provide a kind of energy-saving power amplifier temperature control stepless air-cooled radiating device, by set temperature transducer bottom radiator, and temperature is passed to controller in real time, controller carries out stepless air-cooled forced heat radiation according to the temperature information receiving in real time to radiating fan system, efficiently solve power amplifier not difference in the same time heat radiation in service requirement, reach energy-saving and cost-reducing object simultaneously.
Technical solution of the present utility model is: the stepless cooling and radiation device of a kind of energy-saving power amplifier temperature control, comprise that radiator, radiating fan system, controller, temperature sensor bury groove, temperature sensor underground, the bottom of radiator is provided with thermal source contact area, intra-zone set temperature transducer is buried groove underground, inside grooves is buried temperature sensor underground, and adopt the bonding interface of special adhesive, make radiator bottom smooth, smooth.
Further, described temperature sensor connects controller, and controller is bolted the bearer bar of radiating fan system, and radiating fan system is bolted on radiator.
The utility model has the advantage of by set temperature transducer bottom radiator, heat source temperature is real-time transmitted to controller, controller carries out stepless speed regulation control according to real-time heat source temperature to fan, realize stepless wind-cooling heat dissipating, both meet power amplifier heat radiation requirement, reached again energy-conserving and environment-protective object.
