Description

Hot plume generator

Technical field

The utility model belongs to the heat transfer technology field, is specifically related to a kind of hot plume generator.

Background technology

Fan cooling is heat dissipating method commonly used at present, and shortcoming has been noise, and energy consumption is arranged, and has dust and air exchange to be subject to the adverse effect of environment.Heat loss through convection is a kind of radiating mode of fan-free, heat loss through convection mode commonly used is to adopt thick and heavy metal parts to increase the contact area of thermal source and air at present, this can increase the cost that heat radiation brings on the one hand, the distance of pyrotoxin and metal parts also is subject to the restriction of adopting heat pipes for heat transfer distance and efficient simultaneously, what is more important, the mode of this heat radiation can not be applicable to high-power heat-dissipation, and is subject to the restriction of existing electronic product structure.Therefore, how heat loss through convection is successfully applied to the heat dissipation problem of electronic product, can either comply with the structure and layout of current electronic product, can effectively dispel the heat again, accomplishes simultaneously still not to be resolved economy and durability up to now.

After hot plumage refers to fluid and is heated, because density reduces, around under the effect of fluid buoyancy, the mushroom liquid flow that forms, under convection environment, hot plumage generally originates from the thermal boundary layer of fluid, and a plurality of hot plumages gather together and will form hot plume, it is generally the circulation of hot plume that large scale in convection current flows, and hot plume has played main effect in the convection heat transfer' heat-transfer by convection process.

Defective for fan cooling, need to propose a kind of method with the heat loss through convection successful Application, can either comply with the structure and layout of current electronic product, can effectively dispel the heat again, accomplish simultaneously economy and durability, more can meet the ecological livable tendency consumption concept of people.

Summary of the invention

Shortcoming for existing fan cooling and heat loss through convection, the utility model is as an important component part in a whole set of bionical heat loss through convection scheme of inventor's proposition, a kind of hot plume generator is provided, is applied to be close to the position of thermal source, realize the function of thermal source heat drive fluid motion.

the utility model is to realize like this, a kind of hot plume generator, by fluid, fluid conduit systems, fluid inlet, fluid issuing, the limit wall, fluid-filled chamber and multi-disc heat exchanging fin form, comprise fluid-filled chamber and multi-disc heat exchanging fin in the volume that the limit wall surrounds, be filled with fluid in fluid-filled chamber, at least a slice heat exchanging fin is divided into fluid inlet and fluid issuing with the fluid inlet and outlet decile, there is pointed projection on the surface of described heat exchanging fin, form the passage that can allow flow cross between adjacent two heat exchanging fins, the communication of fluid import without barrier of described passage and fluid issuing, the angle that described passage and vertical direction are is less than 60 degree, the angle that described fluid conduit systems and vertical direction are is less than 60 degree.

Preferably, the angle that in the direction of the pointed projection in described heat exchanging fin surface and passage, the direction of Fluid Flow in A is is less than 90 degree.

Know-why of the present utility model: fluid conduit systems of the present utility model is placed along vertical direction, make the limit wall be close to pyrotoxin, heat conducts to heat exchanging fin, the fluid of heat exchanging fin circumference, hot fluid along the projection rising on heat exchanging fin surface, forms hot plumage under buoyancy; A plurality of heat exchanging fin rats rise the hot plumage that comes and form hot plume, and hot plume converges to fluid issuing along the channel flow between the adjacent heat changing plate, and then rises along fluid conduit systems; Inner at elongated fluid conduit systems, hot plume is benefited from stack effect, can obtain certain flowing velocity; In this simultaneously, cold fluid constantly replenishes by fluid issuing and enters fluid-filled chamber, is again become hot plume by the heat exchanging fin heating; Fluid conduit systems of the present utility model is connected fin, just can realize that hot plume is back to fluid-filled chamber after fin turns cold, realize the heat exchange under hot plume driving.

Technique effect of the present utility model: fan-free, noiseless, the heat radiation object space can be realized totally-enclosed, the utility model is easily installed, and easily expansion easily adapts to the structure and layout that have electronic product now, as the part of imitative plant shaping, easily be accepted in appearance.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Below in conjunction with above-mentioned drawings and Examples, the utility model is described in further detail.
