Abstract
The utility model relates to a heat dissipation device of a computer, in particular to a cooling circulation system of a central processing unit (CPU) of a notebook computer. In a machine shell, the top surface of the CPU is bonded with a semiconductor chilling plate through silica gel, a chip heat dissipation fan is arranged above the semiconductor chilling plate, the semiconductor chilling plate is connected with heat dissipation fins respectively through two heat pipes, the two heat dissipation fins are respectively located at two sides of the machine shell, and an organic heat dissipation fan is installed at the outer side of one of the heat dissipation fins. The cooling circulation system of the CPU of the notebook computer integrates the advantages of the semiconductor chilling plate, the heat dissipation fins and the heat dissertation fans, and is efficient in heat dissipation for the notebook computer.
Description
Technical field
The utility model relates to computer radiating apparatus, particularly a kind of notebook central processing unit cooling recirculation system.
Background technology
Notebook computer because of its compact conformation, be easy to carry, also can provide simultaneously the function identical with desktop computer and performance and very popular.But the above-mentioned feature just because of notebook, need in very compact volume, reach higher runnability, so that there is inadequate natural endowment in notebook computer at radiating capacity of equipment, and the bad one side of dispelling the heat causes the computer operational efficiency to descend, also affect on the other hand user's use impression, reach the heat radiation purpose so notebook will adopt than the more measure of desktop computer.Along with multi-core central processing unit popularizing in notebook computer, heat dissipation problem becomes increasingly conspicuous.
The utility model content
The purpose of this utility model is to provide a kind of mobile computer multi-core central processing unit cooling recirculation system of good heat dissipation effect.
The purpose of this utility model is achieved through the following channels: a kind of notebook central processing unit cooling recirculation system, in casing, the central processing unit end face is stained with semiconductor chilling plate by silica gel, the semiconductor chilling plate top is equipped with the chip cooling fan, semiconductor chilling plate connects respectively a radiating fin by two heat pipes, two radiating fins lay respectively at the both sides of casing, and wherein the outer side edges of a radiating fin is equipped with the body radiator fan.
As the further optimization of scheme, the air outlet of described radiator fan is positioned at the sidewall of casing.
As the further optimization of scheme, described chip cooling fan is the magnetic bearing fan.
A kind of notebook central processing unit of the utility model cooling recirculation system, when notebook computer normally moves, the heat that its central processing unit produces is directly taken away by the chip cooling fan on the one hand, pass on the other hand the heat-absorbent surface of semiconductor chilling plate, and then quick collecting is to the heat delivery surface of semiconductor chilling plate, and then pass to heat pipe evaporator section, make the actuating medium heat absorption vaporization in the heat pipe evaporator section, under differential pressure action, the steam Rapid Flow is to heat pipe condenser section, by radiating fin and radiator fan that heat is quick, efficiently be discharged in the notebook external environment condition and go, under the liquid-sucking core capillary suction force effect of thermotube shell inwall, the actuating medium in the heat pipe condenser section flows back to heat pipe evaporator section and continues absorbing heat.So circulation, heat constantly is transported to the low temperature place from high temperature, satisfies the radiating requirements of high-performance notebook computer.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Among the figure, casing 1, central processing unit 2, semiconductor chilling plate 3, chip cooling fan 4, heat pipe 5, radiating fin 6, body radiator fan 7, air outlet 8.
Embodiment
As shown in Figure 1, a kind of notebook central processing unit of the utility model cooling recirculation system, in casing 1, central processing unit 2 end faces are stained with semiconductor chilling plate 3 by silica gel, semiconductor chilling plate 3 tops are equipped with chip cooling fan 4, semiconductor chilling plate 3 connects respectively a radiating fin 6 by two heat pipes 5, two radiating fins 6 lay respectively at the both sides of casing 1, wherein the outer side edges of a radiating fin 6 is equipped with body radiator fan 7, and the air outlet 8 of body radiator fan 7 is positioned at the sidewall of casing 1.
Chip cooling fan 4 is the magnetic bearing fan, and the magnetic bearing fan is to utilize magnetic force to realize contactless novel bearing, have contactless, do not need lubricated and a series of fine qualities such as sealing, vibration are little, long service life, maintenance cost are low.Be particularly suitable in this programme, using.
