Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of cooling effectiveness height, use for diesel engine air intercooler stable and reliable for performance.
For achieving the above object, the utility model is taked following technological scheme: a kind of use for diesel engine air intercooler, it is characterized in that: it comprises a casing, described casing is surrounded by last lower perforated plate and two side guard plates, on lower perforated plate on the described casing, be provided with one respectively and be communicated with water cover, described two are communicated with the mouth of a river that water cover is respectively arranged with a connection cooling source, described two side guard plates are provided with the be cooled attachment hole of equipment of some installations, in described casing, be horizontally disposed with the multilayer cooling fin, on described on lower perforated plate and the cooling fin, correspondence is provided with some cooling tube mounting holes, near each described cooling tube mounting hole, be symmetrically arranged with the auxiliary cooling hole of a pair of cattle horn shape, vertically in each described corresponding cooling tube mounting hole that is provided with connect a cooling tube by the expanded joint mode.
The edge of described cooling tube mounting hole is to the rat of described cooling fin.
The height that the edge of described cooling tube mounting hole raises up is 2mm.
The edge in described auxiliary heat dissipation hole is to the one side projection of described cooling fin, and this protruding height is lower than the height of projection at described cooling tube mounting hole edge.
Described cooling tube mounting hole is checkerboard and neatly distributes, the interlaced setting of cooling tube mounting hole between adjacent two rows.
The utility model is owing to take above technological scheme, it has the following advantages: 1, the utility model is provided with the auxiliary cooling hole of cattle horn shape near cooling tube, not only reduced the windage of intercooler effectively, and played the effect of abundant flow-disturbing, improve heat-transfer coefficient and heat exchange efficiency effectively, thereby increased the combustion utilization efficiency of diesel engine.2, the utility model makes cooling tube fully contact with cooling fin with tube sheet, compared with the prior art the mode of tube sheet, cooling fin and cooling tube employing expanded joint, not only connect more firm, good airproof performance can not cause and leak, and has improved the stability and the reliability of intercooler effectively.3, therefore the utility model can make the area of contact increasing of cooling fin and cooling tube owing to be provided with projection at the edge of the mounting hole of cooling fin, and cooling effect is better; Simultaneously, therefore make it have wind direction guide functions preferably, further strengthened the flow-disturbing effect and improved heat exchange efficiency owing to be provided with projection at the edge of the auxiliary cooling hole of cooling fin.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises a casing 1, casing 1 is surrounded by upper and lower tube sheet 2 and two side guard plates 3, in casing 1, be horizontally disposed with multilayer cooling fin 4 from top to bottom, be spaced apart 2mm (being not limited to this) between the cooling fin 4, on upper and lower tube sheet 2 and cooling fin 4, vertically be equipped with some cooling tubes 5, on lower perforated plate 2 on the casing 1, connect a connection water cover 6, two connection water covers 6 by bolt respectively and be respectively arranged with a mouth of a river that is connected with cooling source 7.Two side guard plates 3 are provided with some attachment holes, are used for being connected by bolt 8 with the equipment of being cooled.
As shown in Figure 3, Figure 4, in the foregoing description, the corresponding respectively cooling tube mounting hole 9 that is provided with circle on two tube sheets 2 and each cooling fin 4, the one side at each mounting hole 9 edge (top or following) all punching press has the high projection of 2mm, is used for determining the spacing between each cooling fin 4 and increases area of contact between cooling fin 4 and the cooling tube 5.Be symmetrically arranged with two auxiliary cooling hole 10 that are the ox horn shape near one side of each mounting hole 9, the edge of each auxiliary cooling hole 10, the one side (top or following) identical with mounting hole 9 projectioies also punching press has a projection, and this protruding height is lower than the projection at mounting hole edge.When high temperature air passes through to assist cooling hole 10, can produce certain guide functions, and then on cooling fin 2, form the different air-flow of direction, make flow-disturbing more abundant.Mounting hole 9 of the present utility model is checkerboard and neatly distributes, mounting hole 9 between adjacent two rows is interlaced settings, be that mounting hole 9 is to be provided with one every one, mounting hole 9 four adjacent positions are not provided with mounting hole 9, so both can make the density of mounting hole 9 can be not excessive, also can make full use of cooling space.
The utility model is not the welding manner that adopts when cooling fin 4 is connected with cooling tube 5, but adopts the expanded joint mode.Such as, cooling tube 5 in the present embodiment adopts the round copper pipe of φ 10 * 0.75mm, at first cooling tube 5 is plugged in tube sheet 2 and the cooling fin 4 corresponding mounting holes 9 that are provided with, be that the steel ball of φ 8.732 is packed the cooling tube 5 of φ 8.5mm into (as example then with diameter, but be not limited thereto) end of technique head arranged, one of one pipe, utilize hydraulic expanding tube machine and quick chuck, aiming at cooling tube 5 has an end of steel ball to suppress, steel ball is under the high pressure effect, do not have an end of technique head to extrude from cooling tube 5, can finish the expanded joint process.The cooling tube 5 of finishing expanded joint fully contacts with upper and lower tube sheet 2 and each cooling fin 4, can bear the pressure of 10kg and does not leak, and has guaranteed the stability and the reliability of the utility model performance.
When the utility model uses, two side guard plates 3 of casing 1 are connected with the equipment of being cooled by bolt, the cooling liquid of low-temperature receiver enters from the connection water cover 6 of casing 1 bottom, gets back to low-temperature receiver from connection water cover 6 outflows at casing 1 top; Need the air of cooling, enter from casing 1 front, after cooling fin 4 and cooling tube 5 coolings, the input diesel engine so moves in circles, and reaches air cooled purpose.
