Background technology
Along with the develop rapidly of electron trade, the performance of electronic device is become better and better, and integrated level is more and more higher, and the power that unit are electronic component can produce is corresponding also increasing.In late 1990s, the heat flow density that main frame chip can produce just reaches 100W/cm
2.For the inner space that electronic device is narrow and small, so high heat flow density can make electronic device produce local or integral high-temperature, gently then can make the hydraulic performance decline of electronic equipment, heavy then produce thermal deformation, causes electronic device fatigue damage or inefficacy.According to statistics, the inefficacy of electronic device of about 55% is all by local or bulk temperature is too high causes.The exothermic temperature of electronic chip has become one of bottleneck problem that restriction electronic device and equipment thereof further develops.How effectively the temperature of electronic device to be controlled within the scope of operating temperature ratings, more and more become the topic that electron trade is paid close attention to.
With regard to present circumstances, hot pipe technique, with features such as its high efficiency, reliability, compactedness, economy, is one of thermal control technology that can meet dissipation from electronic devices demand.Especially for the situation of high heat flux, remote heat radiation, hot pipe technique has the incomparable superiority of other heat dissipation technologys.Except above advantage, pulsating heat pipe is inner can be bent arbitrarily generally without capillary wick, and has the advantages such as size is little, structure simple, the variation of the heating type of cooling.The heat dissipation element that these advantages make it be very suitable for as short space, high heat flux situation.
Traditional pulsating heat pipe generally has evaporation section and the condensation portion of identical or similar sizes, and its practical application will be subject to certain restrictions, and its heat transfer property also can be affected simultaneously.
Utility model content
In order to overcome the shortcoming of prior art, the utility model proposes a kind of novel pulsating heat pipe.It adopts different pipeline density degree at evaporator section and condenser portion.Flat evaporator section pipeline arrangement closely, significantly can reduce the area of evaporimeter, make it be applicable to very much being applied to the heat radiation of small size electronic device.Pipeline arranges sparse condenser portion can obviously increase its area of dissipation, can also adopt the different types of cooling according to different radiating requirements.
The technical scheme that pulsating heat pipe of the present utility model adopts is as follows:
A kind of pulsating heat pipe, comprises snakelike pipeline, evaporimeter, condenser, topping up pipe and working media.
Described pulsating heat pipe is closed circuit type pulsating heat pipe.
Described snakelike pipeline has different arrangement modes at different parts.In evaporator section arrangement closely, and sparse in condenser portion arrangement, can equidistantly or unequal-interval between tube and tube.
Described evaporimeter is made up of two pieces of rectangular slabs with conduit, and the connected mode of two boards can be connector and connects or welding.
Described topping up pipe and snakelike pipeline are linked together by welding manner.
Described condenser can be fin or fan and fin and combines or cooled plate.
The beneficial effects of the utility model:
A kind of pulsating heat pipe involved by the utility model has novel pipeline arrangement mode, and manufacture craft is simple, simple structure is compact, with low cost, range of application is more extensive.
The arrangement of evaporator section pipeline closely, can effectively reduce the area of evaporimeter to be suitable for the heat radiation of small space.
Evaporimeter is fastened by pipeline and two boards and forms, and can be directly installed on electronic device surface, effectively eliminates the generation of electronic device surface hot spot phenomenon.
The arrangement of condenser portion pipeline is sparse, and that can do is very large, increases heat dissipation capacity.The no type of cooling can also be adopted according to different radiating requirements.
