It is to be understood that these sections and the corresponding ports are defined for convenience of description and understanding only, and in actual practice, there are no obvious boundaries between the sections. Furthermore, the channel 3 can also be made of an integrally formed pipe.
The heat exchange medium filled in the channel 3 may be a refrigerant such as ammonia (code: R717), freon-12 (code: R12), freon-22 (code: R22), or the like.
The heat dissipation principle of this radiator does: the liquid heat exchange medium in the heat absorption end 1 absorbs the heat emitted by the chip 4 of the electric control board and then is converted into a gaseous state, due to volume expansion of the heat exchange medium after vaporization, the subsequent continuously vaporized heat exchange medium can push the previously vaporized heat exchange medium to move, under the guidance of the structure of the channel 3, the vaporized heat exchange medium is conveyed to the heat dissipation section 31 through the second connection section 32, is continuously condensed in the heat dissipation section 31 and is discharged to the outdoor environment by means of the first heat dissipation unit 21 and the second heat dissipation unit 22, and accordingly, the gaseous heat exchange medium is condensed into a liquid state. The liquid heat transfer medium is returned to the heat absorption section via the first connection section 30 and then enters the next circulation path. Like this, through heat transfer medium's gas-liquid conversion, can be constantly with the heat transfer that chip 4 gived off to heat dissipation end 2, then with the help of the radiating unit of heat dissipation end 2 with the heat transfer to the environment in, realize thermal quick discharge to reach fine radiating effect.
Furthermore, in order to guide the circulation of the heat exchange medium in the channel 3, the channel 3 in this embodiment is further provided with a texture, the texture is formed at least in the first connection section 30, the texture is a structure similar to an internal thread, and the spiral direction of the texture is consistent with the circulation direction of the heat exchange medium. The structure of line makes and forms certain capillary force in the passageway 3, when liquid heat transfer medium circulates in the passageway 3 that has the line, can be directional circulation under the guide of capillary force to it is more smooth and easy to make the circulation process, and can improve heat transfer medium's circulation speed, and then improves heat exchange efficiency.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the utility model, and the technical scheme after the changes or substitutions can fall into the protection scope of the utility model.
