Staggered-tooth flat-bottom type intercooler turbulence sheet

Technical Field

The patent of the utility model relates to a staggered teeth flat bottom type intercooler turbulence piece, for heat exchange element-heat dissipation area, turbulence piece of car and industrial engine cooling system's intercooler, belong to turbulence piece design technical field.

Background

In order to achieve as low a charge air temperature as possible, it is common in aviation and automotive engines to use air-cooled charge air coolers, the charge air flowing through flat tubes, in which flat tubes internal turbulence fins can be provided, and between which heat-dissipating strips for the cooling air are arranged. The parts of the cooling core are made of aluminum and are connected by brazing, the bending part of the original common wavy strip is in an arc shape, the contact point of the arc and the plane tangent part of the cooling pipe is the contact point of the arc and the plane tangent part of the cooling pipe, and the arc and the plane tangent part of the cooling pipe extend to form a straight line along the width direction of the cooling pipe, so that the contact between the common radiating strip and the cooling pipe is actually linear contact, and the radiating performance is poor.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a to above-mentioned prior art not enough, provide a rational in infrastructure simple, the production is made easy, convenient to use's wrong tooth flat bottom type intercooler turbulence piece.

The utility model aims at realizing like this, a staggered teeth flat bottom type intercooler turbulence piece, characterized by: the heat dissipation belt comprises a plurality of heat dissipation belts, wherein the heat dissipation belts are wave-shaped heat dissipation belts, and the curved bottoms on the heat dissipation belts are planes; the adjacent heat dissipation belts are fixedly arranged in a parallel and staggered manner. The staggered arrangement may be such that the first row is coincident with the third row, the second row is coincident with the fourth row, odd numbers are the same structure, even numbers are the same structure, and even and odd numbers are staggered.

The heat dissipation belt is fixedly connected with the heat dissipation belt in a welding mode.

The airflow direction of the heat dissipation belt is designed to be in staggered arrangement, and turbulence is increased.

The utility model discloses rational in infrastructure simple, manufacturing is easy, convenient to use, through the utility model discloses, a pair of staggered teeth flat bottom type intercooler turbulence piece is provided, the utility model discloses a derived on the basis in former ordinary heat dissipation area. The original common wavy strip is changed into a flat bottom in the arc shape at the bending position, and the straight grain shape is changed into a staggered tooth structure, so that the heat conduction area from the pipe to the heat dissipation strip is enlarged, the heat dissipation performance is improved, the welding strength among elements is enhanced, and the direct influence on the overall vibration resistance, the stable heat transfer and the service life of the intercooler is generated.

In the tube-and-band intercooler, the surface area of the heat dissipation band participating in heat exchange accounts for about 70% of the whole intercooler. In order to enhance the heat dissipation performance of the intercooler, the heat transfer area between the heat dissipation belt and the cooling pipe is reasonably enlarged, so that the heat dissipation performance of the whole intercooler is improved. The utility model provides a technical scheme that its technical problem adopted is: the arc shape of the bending part of the original common wavy belt is changed into a flat bottom shape, and meanwhile, the turbulence sheet is added in the cooling pipe. The radiating strip obviously increases the heat conducting area of the cooling pipe to the radiating strip, and strengthens the welding strength between the elements.

The utility model discloses a most beneficial effect is: the heat transfer area between each heat exchange element is increased, the overall welding strength of the intercooler is improved, and the service life of the intercooler is prolonged.

Detailed Description

The invention will be further explained with reference to the drawings and the accompanying description.

A staggered-tooth flat-bottom type intercooler turbulence sheet comprises a plurality of heat dissipation belts 1, wherein the heat dissipation belts 1 are wave-shaped heat dissipation belts, and the curved bottoms 2 on the heat dissipation belts 1 are planes; in the plurality of radiating belts 1, the radiating belts 1 and the radiating belts 1 are fixedly arranged in parallel, the adjacent radiating belts 1 and the radiating belts (1 are fixedly arranged in parallel in a staggered manner, the bent part of one radiating belt 1 is arranged in a staggered manner with the bent part of the other radiating belt 1, and the radiating belts 1 are fixedly connected with the radiating belts 1 in a welded manner.

Fig. 1 and 2 are schematic structural diagrams for comparison. FIG. 4 is a comparison of the heat dissipation schematic of FIG. 5, wherein the downward arrows in FIG. 4 and FIG. 5 indicate the flow direction of high temperature fluid, the upward arrows indicate the flow direction of low temperature fluid, FIG. 4, 11 is heat exchange zone, 22 is brazing angle, 33 is cooling pipe wall, and 44 is solder; from these four figures, it can be seen that the bending part of the conventional heat dissipation band is in the shape of an arc, the contact point between the arc and the plane of the cooling pipe is the tangent point, and the arc extends to form a straight line along the width direction of the cooling pipe, so that the contact between the conventional heat dissipation band and the cooling pipe is actually linear contact. However, the contact between the flat-bottom type heat radiation band 1 and the cooling pipe (cooling pipe wall 3) becomes a flat contact, and the effective brazing area thereof is about 2 to 3 times that of the conventional heat radiation band. And simultaneously, the utilization rate of the brazing filler metal (soft solder 4) on the cooling pipe is also improved. The whole strength of the core after being brazed is much better than that of the original structure, and the heat dissipation performance is greatly improved compared with the prior art. FIG. 6 shows a cross-teeth type structure turbulence sheet derived from a flat-bottom type heat dissipation band, which is the same principle as the flat-bottom type heat dissipation band.
