The utility model provides an air-cooling radiator which not only has better cooling effect but also has lower noise. The radiator comprises a radiator body which is a cubic rectangular cylindrical body; one surface of the cubic rectangular cylindrical body is a heat source receiving surface, and each of the other five surfaces is provided with at least one hole; planes formed by the centerlines of all the holes of the adjacent surfaces are dislocated; the holes on the other five surfaces are communicated holes which are dislocated relatively and crossed, so that the honeycomb holes are fully distributed on the surface of the structure of the cubic rectangular cylindrical body; all the communicated holes in the cubic rectangular cylindrical body are mutually interwoven, and all ribs connected among the communicated holes and used for exporting heat are not only separated but also connected; and a cavity is arranged between the lower part of the radiator body and a cooling fan. The radiator overcomes the disadvantages of the traditional air-cooling radiators, and achieves the purposes of cooling effect improvement and noise reduction.

Description

A kind of radiator

Technical field

The utility model relates to a kind of radiator, especially relates to a kind of air-cooled beehive type radiator that adopts.

Background technology

As everyone knows, so far, no matter how its structure changes fan-cooled radiator, all is centered around in various fins or the class fin structure scope.There is following shortcoming in the tradition fan-cooled radiator: 1, be subjected to all multifactor impacts such as processing, material, heat transferred is discrepant to the value on each fin, but because each fin of traditional heat-dissipating device is separate, inequality also can't be transmitted mutually even be heated, and this inequality can cause negative effect to the heat radiation uniformity of heat carrier.2, after traditional heat-dissipating device heat passes on the fin, its radiating effect can only be according to the intensity and the speed of the surface cooling air of experiencing are decided separately, and the wind that cooling fan blows out is own just inhomogeneous theoretically, this heat that each fin is pulled away can't be impartial, can make the temperature inequality of each fin equally, radiating effect is different, also can produce the heat radiation uniform defect of first formation.3, because traditional gilled radiator two sides wherein are open, can cause a large amount of cooling air short circuits, the result of its generation is self-evident.If can cause whole heat carrier temperature to tilt again with air inlet structures such as side direction, tubulars.4, cooling air is in separate state separately after entering the traditional heat-dissipating device all the time, without crossing deciliter processing procedure, just directly discharges, and send different noises with the fin friction separately around here, also discharge in the lump with the wind, meanwhile, the noise that cooling fan itself produces also superposes on it simultaneously.

Notification number is that the utility model patent of CN2583935 discloses a kind of novel air-cooled power electronic device radiator, this air-cooled power electronic device radiator comprises a traditional rectangular fin formula radiator, is a plurality of pin posts that zig-zag type is arranged by equidistant being provided with in the passage between each fin of gilled radiator.The advantage of comprehensive rectangular fin formula of this radiator and pin column radiator, thermal resistance reduces by 10%～20% approximately; When wind speed was 2m/s, the flow resistance of gas in radiator passage was approximately than high by 10% in rectangular fin formula radiator, but the flow resistance of ratio in the pin post radiator of corresponding size is much lower.The utlity model has good heat dissipation effect, characteristics that flow resistance is little.

Notification number is that the utility model patent of CN2667441 discloses a kind of air-cooled fluid radiator, comprise fluid chamber and heat dissipation chamber, the foil interference fit of the radiating tube of some vertical layouts and some transverse arrangement of turbo in the heat dissipation chamber, fluid passage one end of heat dissipation chamber is a cold air inlet, and the other end is a hot-blast outlet.

Summary of the invention

The purpose of this utility model is to provide a kind of not only radiating effect better at the above-mentioned shortcoming of existing fan-cooled radiator existence, and the less fan-cooled radiator of noise.

The utility model is provided with radiator body, radiator body is a column, the wherein one side of column is accepted face for thermal source, be equipped with at least 1 hole on its lap, the formed plane of each centerline hole mutual dislocation of adjacent surface, set hole is the intercommunicating porosity that three-dimensional mutually dislocation intersects on its lap, make the structure of column become the surface and be covered with honeycomb structure, be interweaved between inner each intercommunicating porosity of column, and connect between each intercommunicating porosity and all ribs of being used for heat and deriving had both interconnected the space, between radiator body bottom and cooling fan, be provided with cavity.

Described column can adopt the rectangle column, is preferably six rectangle columns.

Cooling work principle of the present utility model: cooling fan blow out wind be blown into from radiator bottom, airtight cavity (malleation chamber) around having one between fan and the radiator body, make cooling air enter radiator and before radiator is formed a positive pressure environment relatively uniformly earlier, and cooling air only can enter in the radiator body by this passage of radiator bottom, thereby avoided the cooling air short circuit to run off, the effective rate of utilization of cooling air has been reached at utmost.After cooling air enters radiator, because the air flue that set intercommunicating porosity forms in the radiator body extends in all direction, cooling air can be according to the rule of pressure decline, flow arbitrarily in the air flue space of extending in all direction, repeatedly deciliter, thereby reach with radiator body in the heat radiation rib net list face that forms of set intercommunicating porosity fully contact, to greatest extent that it is surperficial heat is taken away, and from hole all around, discharge in regular turn, overcome because processing, the thermal output error that factors such as material cause, forming a heat can transmit between each rib mutually, maintain balanced space heat conduction network body.In this process, the heat in the radiator is also taken out of by wind thereupon, thereby has reached the purpose of heat radiation.Meanwhile, because cooling air in radiator inside repeatedly deciliter, the effect that can produce muffler weakens the gas friction sound between cooling air and the radiator greatly.

This shows, compare with traditional air-cooled radiator, the utility model breaks away from the pattern of traditional heat-dissipating device structural design thinking fully, adopts a kind of heat radiation notion of brand new, overcome the existing shortcoming of traditional air-cooled radiator, reached the purpose that improves radiating effect and reduce noise.
