Description
Technical field
The utility model relates to a kind of heating radiator, is meant a kind of heating radiator that dispels the heat the chamber and be provided with cooling fluid in this heat radiation chamber that comprises in structure especially.
Background technology
The working temperature of well-known electron device directly determines its serviceable life and stability, allow the working temperature of each parts of PC remain in the reasonable range, except the temperature that guarantees the PC working environment in the reasonable scope, also must carry out radiating treatment to it.And along with the enhancing of PC computing power, power consumption and heat dissipation problem become does not day by day allow the problem of avoiding.In general, the thermal source rich and influential family in the PC comprises CPU, mainboard, video card and miscellaneous part such as hardware, CD-ROM drive etc., and the electric energy that consumes during their work has quite a few and is converted into heat.Especially for CPU, guarantee its more necessary heat radiation effectively of stably working.
It roughly can be divided into following several for general radiating principle, first kind, material itself or when material contacts with material, the transmission of energy just is called as heat conduction, this is the most general a kind of thermaltransmission mode, and particle and the energy higher particle direct contact-impact lower by energy transmit energy.Second kind, the convection current conduction, convection current refers to fluid (gas or liquid) and contacts the thermaltransmission mode that causes fluid from solid surface the torrid zone to be walked with solid surface.The third heat radiation mode, heat radiation are a kind of can the needs to contact under the situation without any medium, and the transfer mode of heat interchange just can take place, and that is to say, heat radiation is exactly the purpose that reaches heat interchange with the form of ripple in fact.
General heating radiator all can use above three kinds of thermaltransmission modes simultaneously, just stresses different.With the CPU heat radiation is example, and whole heat transfer process comprises 4 links, the firstth, and CPU, it is that thermal source produces the survivor, heat is constantly come out by CPU work; The secondth, base and heat radiator are the conductors of heat, and the cooling fin fin base that base and core cpu closely contact is to be delivered to heat radiator with heat in the mode of conducting; The 3rd is that fan is to increase heat conduction and point to heat conducting media, and the heat that arrives heat radiator blows by other modes such as fan again sees heat off; The 4th is air, and this is the final flow direction of heat interchange.But with regard to the heat abstractor that occurs on the market now, its structure all includes only solid tabular heat radiator and fan, it is best that its radiating effect of the radiating mode of this structure often can not reach, and radiating efficiency is also lower, and this is the major defect for conventional art.
