Abstract

The utility model discloses a heat radiation leaf. The heat radiation leaf comprises a fluid conduit, a fluid and a heat radiation leaf blade, wherein the heat radiation leaf blade comprises an upper surface, a lower surface, a fluid chamber and a fluid inlet and outlet port; the fluid conduit is connected with the fluid inlet and outlet port; the volume enclosed by the upper surface and the lower surface is the fluid chamber; leaf stem vein-shaped flow guide grooves are formed in the lower surface; the leaf stem vein-shaped flow guide grooves are gathered together at the fluid inlet and outlet port; and the farther the leaf stem vein-shaped flow guide grooves are from the fluid inlet and outlet port, the smaller the cross section areas of the leaf stem vein-shaped flow guide grooves are. The heat radiation leaf disclosed by the utility model has the advantages of simple structure, low making cost, easiness fore removing dust, no fan, no noise, easiness in mounting and expanding and plant-like appearance, easily adapts to the structure and layout of the traditional electronic product and is easily accepted by the people.

Description

The heat radiation leaf

Technical field

The utility model belongs to the heat transfer technology field, is specifically related to a kind of heat radiation leaf.

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.

In heat dissipation technology, nearly all heat is all to be dispersed in air, the general position that contacts with air is in order to increase surface area, often adopt the structure of a plurality of radiating fins side by side, although this structure can increase the contact area with air, but can not coordinate with domestic environment, be difficult to directly as outward appearance, the outside often needs to add covering, will suppress like this flowing of air, and cause the designer to have to introduce fan.In addition, the complex manufacturing technology of radiating fin, material cost is high, and the shape of radiating fin is subject to the serious restriction in space.When dust is attached to the radiating fin surface, heat dispersion can reduce, and these dusts are difficult to remove with rag, often needs to use high pressure draught, has so greatly limited the frequency of removing dust, has promoted disposal costs.

For the defective of radiating fin, need to propose a kind of new heat dissipating method, 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 radiating fin, the utility model is as an important component part in a whole set of bionical heat loss through convection scheme of utility model people proposition, a kind of heat radiation leaf is provided, is applied to large tracts of land and is exposed in air, realize that heat is transmitted to airborne function.

The utility model is to realize like this, a kind of heat radiation leaf, formed by fluid conduit systems, fluid and radiator shutter, radiator shutter is comprised of upper surface, lower surface, fluid chamber and fluid inlet and outlet, and fluid conduit systems connects fluid inlet and outlet, and the volume that upper surface and lower surface surround is fluid chamber, lower surface has leaf stem veiny guiding gutter, leaf stem veiny guiding gutter collects at fluid inlet and outlet, and leaf stem veiny guiding gutter is more away from fluid inlet and outlet, and the cross-sectional area of leaf stem veiny guiding gutter is less.

Preferably, the angle that is of described fluid conduit systems and vertical direction is less than 60 degree.

Preferably, described upper surface surpass 20 percent area place the plane direction and the angle that is of vertical direction less than 89 degree.

Preferably, described fluid filling fluid chamber 90 to percent percent ninety-nine volume.

Preferably, described fluid conduit systems filling liquid.

Described fluid is liquid.

Know-why of the present utility model: hot fluid is in thermal source position generation, rise by fluid conduit systems, enter fluid inlet and outlet, due to the upper surface of heat radiation leaf towards vertically upward direction, after hot fluid enters the fluid chamber of heat radiation leaf, continue to flow along the inwall of upper surface, be diverted to each position of the inwall of upper surface, the heat of hot fluid contacts with air by upper surface, and hot-air rises and take away heat at upper surface.After cooling near the hot fluid of upper surface in the back under the promotion of hot fluid the inwall to lower surface flow, leaf stem veiny guiding gutter plays the effect of collecting cold fluid, cold fluid is proceeded heat exchange by lower surface and air, temperature continues to reduce, and cold fluid continues to flow along leaf stem veiny guiding gutter towards fluid inlet and outlet again.So just realized the refrigerating function of hot fluid.Fluid chamber is not filled fully fully, volumetric expansion headspace when solidifying for fluid.Leaf stem veiny guiding gutter plays the effect of reinforcement simultaneously, guarantees that radiator shutter keeps the form that is tilted to, and prevents that radiator shutter from occurring sagging under Action of Gravity Field.

Technique effect of the present utility model is: simple in structure, cost of manufacture is low, easily removes dust, fan-free, and noiseless is easily installed, easily expansion, the easy structure and layout that adapt to existing electronic product, imitative in appearance plant shaping easily is accepted.
