Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of transformer forced air cooler of the utility model, as shown in Figure 1 and Figure 2 and Figure 3, it comprises cooler body 1, the radiating tube 6 arranged in cooler body 1, the fan housing 5 that cooler body 1 side is equipped with and blower fan 3; As shown in Figure 4, on the outer wall of radiating tube 6, both sides are respectively arranged with wave shaped radiator 4, and wave shaped radiator 4 is fixed on the both sides of radiating tube 6 windward side respectively by crest, share a wave shaped radiator 4 between adjacent heat radiation pipe 6.
Wherein, as shown in Figure 4, trough on wave shaped radiator 4 is corresponding with the trough or crest that are positioned at wave shaped radiator 4 adjacent on same windward side to be arranged, this preferred embodiment is set to example explanation with crest to trough, as shown in Figure 4, when amplifying the arranging of multiple radiating tube 6, its crest is to trough, and the connection effect of crest to crest is consistent.As shown in Figure 4, the trough on wave shaped radiator 4 and crest are fixedly connected on corresponding radiating tube 6 by soldering.In this preferred embodiment, be positioned at same cooling airflow wave shaped radiator 4 upwards identical with the soldering horizontal level of corresponding radiating tube 6, formation to parallel cooling air passage with fan shaft, can be beneficial to flowing through smoothly of cooling air, form unobstructed ventilation and heat passage.
In this preferred embodiment, radiating tube 6 adopts cross section to be oval or rectangular structure, existing tubing can be adopted to carry out making or adopt sheet material to carry out processing and obtain, form oily side structure; This preferred embodiment is described for oval pipe, and when adopting oval tubing, oval major axis is parallel with flowing to of cooling air; Radiating tube 6 and wave shaped radiator 4 adopt aluminium alloy or stainless steel to make.
The utility model makes contact point close and firm between radiating tube 6 and wave shaped radiator 4, not yielding and smooth and beautiful appearance by soldering, improve the radiating efficiency of cooler, improve radiating tube and wave shaped radiator intensity, decay resistance and presentation quality, make its maximum cooling capacity reach 800KW, can make under equivalent capability that small product size is less, weight is lighter.
Wave shaped radiator 4 is fixed on radiating tube outside by soldering by the utility model, make radiating tube 6 outer wall and wave shaped radiator 4 close contact, ensure that the heat transfer between radiating tube 6 and wave shaped radiator 4, effective increase cooler area of dissipation, and being more conducive to passing through of cold air, the efficiency of cooler also increases greatly; Under equivalent capability, compare tubular type fin tube type cooler volume reduce, easy for installation, effectively reduce product and maintenance cost.By adopting soldering in radiating tube 6 and wave shaped radiator 4 contact portion, the aluminium alloy that before can adopting, syndeton cannot adopt or stainless steel, thickness also can adjust as required, wave shaped radiator 4 is not yielding, in addition stable connection, thus it is more corrosion-resistant, the instructions for use of cooler product in the serious area of saline alkali corrosion can be solved, the flushing directly can also carrying out water under high pressure or gas is safeguarded, the rate of heat dissipation of effective maintenance cooler reduces the failure rate of product, increases the reliability of cooler.
