Abstract
A computer CPU radiating device using thermo-sensitive magnetic fluid is an organic integrity composed of an annular permanent magnet, a heat absorber, a magnetic fluid circuit, radiating fins and a fan. The heat absorber is closely bonded on the CPU to absorb the heat generated by the CPU. By means of thermal magnetic properties of the thermo-sensitive magnetic fluid, a driving force for driving the circular flow of the magnetic fluid in the circuit is generated under the action of the magnetic field, and magnetic fluid with high temperature is transmitted to a radiating area for radiating. The fan in the radiating area is used for assisting radiation. According to the CPU radiating device, the magnetic fluid is used for circular radiation in the circuit, and the radiating efficiency is high. Power for the flow of the magnetic fluid is provided through the conversion of thermal magnetic energy and mechanical energy in the thermo-sensitive magnetic fluid, actuating mechanisms are not needed to be added externally, and energy is saved. The radiating device is simple in structure, easy to manufacture, and low in manufacturing cost.
Description
Affiliated technical field

Background technology
Heat radiation is the necessary condition that guarantees the computer CPU operate as normal, and the CPU heat radiation does not cause computer a lot of faults to occur.At present, computer heat radiation mainly is that radiating effect is undesirable with the aluminium flake heat radiation.Cause computer often because of bad the operation slowly of dispelling the heat, burn video card mainboard etc., shine into serious economy loss.
The utility model content
In order to overcome the unfavorable shortcoming of existing computer heat radiation dress radiating effect; The utility model is applied to the notebook computer heat radiation with the temperature-sensitive magnetic fluid as heat eliminating medium; Designed computer heat radiation loop based on the temperature-sensitive magnetic fluid; Magnetic fluid circulates heat radiation in the loop, increased radiating efficiency greatly.
The utility model solves the technical scheme that its technical matters adopted: this temperature-sensitive magnetic fluid heat abstractor is made up of absorber, pipeline, heat radiator, annular permanent magnet, fan.The closed circuit that absorber, pipeline, heat radiator connect in order; Be full of the temperature-sensitive magnetic fluid in the loop; Flow to the absorber porch at the temperature-sensitive magnetic fluid permanent magnet generation magnetic field is installed; Field drives temperature-sensitive magnetic fluid circulates in pipeline and takes heat to radiating area realization heat radiation, and the fan auxiliary heat dissipation is set near the radiating area.Permanent magnet is designed to annular to be enclosed within the temperature-sensitive magnetic fluid and to flow on the pipeline of porch of absorber.Absorber is bonded in the CPU surface with silica gel or other good thermal conductor, and magnetic fluid absorbs the heat that CPU produces in the absorber, and temperature raises; The magnetization reduces, and field drives power reduces, and the magnetic fluid temperature is low in the pipeline of absorber porch; The magnetization is high; The driving force in magnetic field is also big, and two power interact and form eddy current in the absorber porch, promote magnetic fluid and in the loop, circulate.When the CPU quantity of heat production increased, the intensification amplitude of magnetic fluid strengthened, and field drives power increases, and the magnetic fluid circulation is accelerated, and heat radiation also can be quickened, and this has just played with cpu temperature and has changed the effect that intelligence changes heat dissipation capacity, makes cpu temperature be stabilized in reduced levels.Magnetic fluid circulates and takes heat to heat radiator.The fin section design is like Fig. 2, and the magnetic fluid pipeline bends at radiating area, and twice the reinforcement heat radiation is provided with fan, auxiliary heat dissipation near heat radiator through heat radiator.
The beneficial effect of the utility model is that magnetic fluid circulates heat radiation in the loop, the radiating efficiency height.Utilize the pyromagnetic mechanical energy that can convert into of temperature-sensitive magnetic fluid power to be provided, need not add power original papers such as pump, save the energy for closed circuit.This loop structure is simple, and production cost is low.
