Novel water-filled radiator
The utility model relates to a kind of water-filled radiator, relates in particular to the improvement of diesel power generation unit water cold heat sink structure.
Existing diesel power generation unit water cold heat sink, its upper and lower hydroecium is to be connected by several passages, and the high temperature water inlet enters lower header by upper tank by the passage that is positioned at cooled region, and high-temperature water cools off in half-duplex channel, and the effect of cooling is bad.Its reason is very directly perceived, and the distance that current move in passage is short, and is short through the time of cooled region.
The utility model content
The utility model provides a kind of range ability that increases current at cooled region at above-mentioned the problems of the prior art, thereby improves the novel water-filled radiator of cooling effect.
The technical solution of the utility model is: comprise upper tank, lower header, plurality of conduits and heat radiation core body, be provided with the pipeline that is the setting of revolution shape between the upper and lower hydroecium.
It also comprises the compartment that the adjacent channel mouth of pipe is communicated with that is arranged in the upper and lower hydroecium.
The pipeline that is revolution shape setting is made of the pipeline of 3 or 5 or 7 pipelines or its multiple.
The utility model has changed the connection pattern of core pipelines, and original upper and lower hydroecium is straight-through by some independently pipelines, changes into by the revolution pipeline being communicated with, and current have been prolonged 3 times at least at the range ability of cooled region, has improved the effect of cooling greatly.Owing to improved cooling effect, under the situation of same cooling energy rate, can reduce the volume of radiator, thereby can reduce the size of diesel engine fan, reduce the power consumption of diesel engine, and then reduce use cost.The utility model can adapt to 60 ℃ of operational environments.

Fig. 2 is an A-A view among Fig. 1
Fig. 3 is the structural representation of another execution mode of the utility model
As shown in Figure 1, 2, the utility model comprises upper tank 5, lower header 7, plurality of conduits 3 and heat radiation core body, is provided with between the upper and lower hydroecium to be the pipeline that the revolution shape is provided with, and links to each other by the revolution pipeline 3 that is the setting of revolution shape between the upper and lower hydroecium.
It also comprises the compartment 2 that the adjacent channel mouth of pipe is communicated with that is arranged in the upper and lower hydroecium.
The pipeline 3 that is revolution shape setting is made of the pipeline of 3 or 5 or 7 pipelines or its multiple.Has a revolution pipe outlet 9 that is positioned at the revolution entrance 1 of upper tank 5 and is positioned at lower header 7 in the revolution pipeline 3 of each connection, compartment 2 sealings are communicated with the entry and exit that are positioned at upper tank 5 and lower header 4 adjacent channels, promptly form the revolution mouth 6 of rotating channel 3.
Operation principle of the present utility model as shown in Figure 1, high-temperature water stream enters upper tank 5 by water inlet 4; Enter revolution pipeline 3 by revolution entrance 1 again, it is up to enter adjacent channel by revolution mouthfuls 6, the compartment 2 that is positioned at lower header, enters the revolution mouth 6, the compartment 2 that are positioned at upper tank 5 again; It is descending to continue to enter adjacent pipeline, enters lower header 7 by revolution pipe outlet 9; Discharge outside the radiator from delivery port 8 at last.Current are compared with the water-filled radiator of original technology, have prolonged three times of distances, and the time of operation obtains prolonging in cooled region 10, has further reduced the water temperature at delivery port 8 places.
As shown in Figure 3, be another execution mode of the present utility model, it can reduce compartment quantity, is convenient to production and processing.It is that upper tank, lower header are provided with three compartments 2 respectively, two-tube and stream, and the cool stream circulation passage has been extended 5 times.
