The specific embodiment
Below in conjunction with the drawings and specific embodiments the heat abstractor that the utility model is used for transducer air conditioning is described further.Be the heat abstractor that is used for transducer air conditioning provided by the utility model in the accompanying drawing 2, comprise base 2 and a plurality of fin 1 that are parallel to each other and distribute that are arranged on the base 2, the top line of fin 1 constitutes waveform.Be provided with the groove 1a and the protruding 1b that are parallel to each other on the radiating surface of fin 1, the bearing of trend of groove 1a and protruding 1b and the bearing of trend of base 2 are consistent.Groove 1a on the base 2 of heat abstractor, fin 1 and the fin 1 and protruding 1b adopt the disposable extrusion molding of aluminium section bar.In conjunction with reference to shown in Fig. 4, the heat abstractor that is used for transducer air conditioning described in the utility model is installed in the median septum 5 of air-conditioner outdoor unit casing, and high power devices 6 such as the electronic control module of transducer air conditioning and IGBT are installed on the base 2 of heat abstractor.
Because fin 1 is that the design undulate changes in short transverse, the wind-force blind area of so effective solution traditional heat-dissipating device is taken away the heat that cooling fin fin base 2 absorbs from high power devices such as electronic control module and IGBT 6 rapidly.In addition, heat abstractor by the moulding of aluminium extrusion technology can effectively improve Pin-Fin than (annotate: Pin-Fin is than being that height (not containing base thickness) with Pin is divided by Fin, Pin is meant the height of fin, Fin is meant the distance between the two adjacent fin), therefore, can under the situation that does not increase material, more effectively increase area of dissipation, improve radiating efficiency.
Since we know the air-cooled air conditioner off-premises station the most widely methods for cooling utilize the outside air blast of axial flow blower exactly, its resultant effect is good and with low cost.If conversely the direction of axial flow blower, just become the inside exhausting of off-premises station, the difference of two kinds of wind pushing forms is the difference of airflow pattern, and what produce during air blast is turbulent flow, and blast is greatly but be subjected to drag losses easily; What produce during exhausting is laminar flow, the little but steady air current of blast.In theory, the heat exchange efficiency of turbulent flow is more much bigger than laminar flow, therefore just becomes air-conditioner outdoor unit main flow design form.According to aerodynamic principle, adopting outside air blast mode is that outdoor fan is in case running, air is under the ordering about of fan 3 flabellums of rotation, along the electrical axis direction center of fan 3 just, form a low pressure vortex that air pressure is low relatively, the air in the outdoor condenser outside is seen through condenser fin by atmospheric pressure moment and is pressed into the low pressure vortex, gets rid of off-premises station through the baffle liner of off-premises station front panel 4, thereby reaches the purpose to the condenser air cooling.In brief, fan running gets up, and the wind direction of cooling air in off-premises station is the baffle liner that is blowed to front panel 4 by condenser side.The fin 1 that is in this direction will be cooled under the wind effect of flowing.The utility model utilizes side direction blowing technology, by changing the installation direction of fin 2, after making heat abstractor be installed on the median septum 5, plane, fin 1 place is vertical mutually with median septum 5 planes and air-conditioner outdoor unit front panel 4, allow airflow direction by changing to fin 1 maintenance level perpendicular to fin 1 originally, also promptly, the gas channel between the fin 1 is consistent with airflow direction.
For realizing the capacity of heat transmission maximization of heat abstractor base, the utility model adopts meticulous drawing process, to guarantee the smooth and smooth of heat abstractor base 2, theoretically, heat abstractor base 2 is closely to contact with high power devices 6 such as IGBT with electronic control module like this, but objective getting on very well, no matter how level and smooth two contact-making surfaces have, still there is air between them, and the heat conductivility of air is very poor, this just need closely be buckled in high power devices such as module and IGBT 6 on the heat abstractor base 2, adopt the better and flexible thing of some heat conductivilitys to replace air to fill up these spaces (as heat-conducting silicone grease or heat radiation adhesive plaster) in addition, to reduce the space between the high-power device contact-making surfaces such as heat abstractor and IGBT, keep in touch the thermal resistance minimum.Test shows, adopts heat abstractor of the present utility model and tradition system heat abstractor to compare, and monitors each original paper that mainly dispels the heat simultaneously.The radiating effect that found that the former obviously is better than the latter, even and the former under worst working condition, also can keep electric control element to run well.
