Description

Radiator

Technical field

The utility model relates to the heat dissipation technology field, espespecially a kind of radiator.

Background technology

Radiator is usually used in the radiating and cooling of power component, many power components are arranged in the product of electron electric power industry, 5% ~ 8% power loss generation heat is in use arranged, component temperature is raise, operating state degenerates, and the reliability decrease is until damage, at every rising 5 degree of the temperature of certain temperature range internal power element, the reliability order of magnitude that just descends, so the performance of radiator directly has influence on the reliability of product.

The characteristics such as at present, radiator is little with its volume, heat-transfer rate is fast, lightweight are widely used in the fields such as computer to dissipate heat, cooling machine cabinet, server radiating and LED heat radiation.On market, the kind of radiator is various, and radiating effect is also different, yet existing radiator heat transfer mode is single, and radiating efficiency is lower, can't meet user's radiating requirements.

Summary of the invention

For the problem that form is single and radiating efficiency is low of radiator in prior art, but the novel radiator that a kind of high efficiency and heat radiation simple in structure is provided of this use.

For reaching above purpose, the utility model radiator mainly by the following technical solutions:

A kind of radiator, comprise the heat conduction main body, and the heat conduction main body is provided with some fin, between two adjacent fin, is equipped with interval, and the surface of described fin is provided with some end to end projections and groove, and the heat conduction main body is provided with can be for the thermal hole of heat pipe insertion.

Preferably, the lower end of described heat conduction main body is provided with mounting groove.

Preferably, parallel mutually between described some fin.

Preferably, the thickness of described some fin all equates.

Preferably, the length between described two adjacent spaces is 5 times to 6 times of thickness of fin.

Preferably, the lateral profile of described some fin compositions is circular arc.

Preferably, described heat conduction main body and the extrusion modling of fin one.

The beneficial effects of the utility model are: by some end to end projection and the groove that arranges at fin, increased the surface area of fin, accelerated the transmission of heat between fin and air, improved the heat dispersion of the utility model radiator; Simultaneously, this kind structure is comparatively simple, and the cost of manufacturing has been saved in convenient processing.

The accompanying drawing explanation

Fig. 1 is the structural representation of the utility model radiator.

Fig. 2 is the enlarged diagram at the A place of Fig. 1.

Embodiment

As shown in Figure 1 and 2, a kind of radiator, comprise heat conduction main body 3, heat conduction main body 3 is provided with some fin 2, between two adjacent fin 2, be equipped with interval, the surface of described fin 2 is provided with some end to end protruding 21 and groove 22, and heat conduction main body 3 is provided with the thermal hole 1 that can insert for heat pipe.Concrete, when work, in thermal hole 1, be inserted with heat pipe, the sidewall close contact of heat pipe and thermal hole 1, heat passes to the utility model radiator by heat pipe, and this radiator is dispersed into heat in air uniformly by the fin 2 that arranges.Wherein, by some end to end protruding 21 and the groove 22 that arranges at fin 2, increase the surface area of fin 2, accelerated the transmission of heat between fin 2 and air, improved the heat dispersion of the utility model radiator; Simultaneously, this kind structure is comparatively simple, and the cost of manufacturing has been saved in convenient processing.

The lower end of described heat conduction main body 3 is provided with mounting groove 4, concrete, when work, in thermal hole 1, be inserted with heat pipe, the utility model radiator is fixed by heat pipe, mounting groove 4 by arranging, can play auxiliary installation fixation, strengthened the installation stability of the utility model radiator.

Parallel mutually between described some fin 2, concrete, by the fin that is parallel to each other 2 that arranges, under the prerequisite that does not reduce the length L 2 between fin 2 and two adjacent spaces, greatly improve the quantity of the fin 2 of installing, further improved the radiating efficiency of the utility model radiator.

The thickness L1 of described some fin 2 all equates, avoids because the rate of expanding with heat and contract with cold of fin 2 each several parts is inconsistent, pernicious distortion occurring in manufacture process, thereby reduces the impact that pernicious distortion produces the length L 2 between described two adjacent spaces.

Length L 2 between described two adjacent spaces is 5 times to 6 times of thickness L1 of fin 2, through actual the detection, learn, when the length L 2 between two adjacent spaces is 5 times of thickness L1 of fin 2, the layout of fin 2 is both not too intensive and affect the heat conduction between fin 2 and air, also not too sparse and reduce the space availability ratio around heat conduction main body 3, structure is optimized fully, and practicality is stronger.Certainly, the length L 2 between described two adjacent spaces can also, for other multiples between 5.5 times, 6 times or 5 times to 6 times of the thickness L1 of fin 2, get final product according to the integral body size of radiator and concrete setting of demand of heat dissipation capacity.

The lateral profile that described some fin 2 form is circular arc, concrete, the top of described fin 2 reduces from longitudinal center's alignment both sides of heat conduction main body 3 gradually apart from the height of heat conduction main body 3 lower surfaces, the arcuate shape that the integral body of some fin 2 is high in the middle of arranging and being, both sides are low, through reality, detect and learn, this kind arcuate structure can effectively improve the flowing velocity of air between fin 2, strengthen the thermal convection between fin 2 and air, improve heat exchanger effectiveness, thereby improve the heat dispersion of the utility model radiator.

Described heat conduction main body 3 and fin 2 one extrusion modlings, avoid in manufacture process, all parts being re-assemblied, and reduced manufacturing procedure, further reduced the production cost of the utility model radiator.

The above execution mode, it is better embodiment of the present utility model, be not to limit the utility model practical range, therefore all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model patent claim.
