Description

Radiating machine casing

Technical field

The utility model relates to the heat abstractor of electronic equipment, relates in particular to a kind of radiating machine casing.

Background technology

At present, on electronic equipment, especially heat radiation is required than on the higher electronic equipment, need by certain means dissipating the heat in the environment of equipment to be gone, the equipment of assurance has stable, a suitable working temperature.The heat exchange method of electronic equipment dissipating heat employing at present mainly contains following three kinds: 1, adopt the heat exchanger of integrated form, this heat exchanger is installed on the casing, comprises adverse current and two kinds of heat exchange methods of intersection, derives heat by accessory fan.The problem that this mode mainly exists is: cost is than higher, and processing technology is loaded down with trivial details; Volume ratio is bigger, and especially heat exchanger size is all bigger, is unfavorable for device miniaturization; And supporting fan required than higher, cause cost to rise equally and the volume increase.2, common radiator, during installation, the one side of radiator touch the components and parts or the parts of heating, and is by the radiation tooth heat radiation of an other end, in the time of necessary, auxiliary with blower fan.The problem of the main existence of this mode is: for heater members, the evenness of at least one face of radiator requires very high, heater members plane closely connected being combined on the spreader surface that be critical, simultaneously, also have a very big problem in this mode: heater members and radiator are in same space, heat is to loose in this space, if heat will export to surrounding environment, then require cabinet or the casing seal can not be too high, otherwise heat can't be distributed, but seal is poor, protective to electronic devices and components is just bad, and dust etc. are just unavoidable to the influence of components and parts.3, adopt blower fan directly to ventilate.In this mode, electronic equipment has certain basic protection, communicates but whole pyrotoxin and external environment are actual, and actual whole system degree of protection is lower.

The utility model content

The technical problems to be solved in the utility model provides that a kind of barrier propterty is good, heat is derived rapidly, radiating machine casing completely.

The utility model solves above-mentioned technical problem by the following technical programs: a kind of radiating machine casing, comprise the polyhedral casing, and on casing, be provided with radiation tooth.

Described casing is six face closure housings, in the interior sidewall surface of casing or/and be provided with radiation tooth on the outer side surface.

Have at least in the composition face of casing on the two side of a face and be interval with a plurality of radiation tooths.

Have at least a face directly to constitute in the composition face of casing by radiation tooth.

Casing is provided with protective cover outward, and protective cover is provided with air inlet, air outlet, and air inlet or air outlet are provided with circulating fan, forms outer circulating air duct between protective cover and the casing.

Be provided with in the casing casing endogenous pyrogen and the separated dividing plate of casing, dividing plate is provided with air inlet, air outlet, and air inlet or air outlet are provided with circulating fan, circulation air path in forming between dividing plate and the casing.

Two side elevations that casing is relative are provided with radiation tooth.

Described protective cover, dividing plate top are provided with air outlet, and the two bottom all is provided with air inlet, and two air outlets are respectively equipped with circulating fan, and described protective cover top is provided with fan shroud, and the air-out passage is left in described fan shroud side.

One end of described radiation tooth is vertically fixed on the casing.

Described radiation tooth is continuous concavo-convex integrative-structure, forms the casing wallboard.

The utility model directly is provided with radiation tooth on casing, wherein a kind of mode is in outside wall surface or/and be provided with radiation tooth on the internal face, another kind of mode is that enclosure wall directly is made of radiation tooth, like this, the heat that the casing endogenous pyrogen produces, lead in the environment by the radiation tooth on the casing, the utility model casing is sealing, the components and parts that produce heat directly are not communicated with external environment condition, barrier propterty is fine, and because radiation tooth has increased the area of dissipation of casing, heat is derived fully, guaranteed that electronic devices and components can work under a suitable stable temperature, and because casing becomes the heat exchange primary structure, compare, reduced occupied space with integrated heat exchanger, can make the electronic equipment integral miniaturization, also making electronic equipment hang wall becomes possibility; Radiation tooth of the present utility model can be installed on the casing wall by modes such as welding, riveted joints, perhaps by one-time formed mode, radiation tooth is directly made enclosure wall, and processing technology is simple, has reduced material to expend, and has lowered cost; Outside casing, be provided with protective cover, casing and radiation tooth are played a protective role, on protective cover, be provided with air outlet, air inlet, and circulating fan is set at air outlet or air inlet, leave outer circulating air duct between protective cover and the casing, under the work of blower fan, the heat in the circulation air path is extracted out or blasted cold air, forced-air circulation can derive heat fast like this; Equally, in casing, be provided with dividing plate, thermal source and casing are separated, also leave interior circulation air path between dividing plate and casing, dividing plate is provided with air inlet, air outlet, at air inlet or air outlet circulating fan is set, the heat that thermal source can be produced is extracted out or is inwardly blasted cold air in the circulation air path, by casing and radiation tooth heat is derived again, reduce the temperature of heating electronic component, make it under suitable stable temperature, to work; Owing to used forced circulation, radiation tooth then is set on two side elevations of casing can derive the heat of thermal source, needn't on each face of casing radiation tooth be set, and has saved material cost; Radiation tooth be shaped as concavo-convex shapes such as flat board, S shape or arc, increased area of dissipation as far as possible, the shedding of accelerated heat.In a word, the utility model had both guaranteed the strict demand of system works part to waterproof and dustproof, EMC etc., utilized inside and outside air to flow through the gear piece of inside and outside heat radiation separately again under the effect of air channel and blower fan separately, carried out heat exchange.
