Today that the design structure is more compact and refined, how to improve the radiating efficiency of the radiator under the condition of limited unit windward positive area is of great importance to product performance and overall design. The aluminum plate fin type radiator has high radiating efficiency, good radiating performance and mature technical design and is widely applied.

As shown in fig. 3, the windward side surfaces of the existing plate fin 1 and the inner fin tube type heat dissipation pipe are planar, the design structure has a large influence on wind resistance of the wind side, especially the plate fin type intercooler structure, in order to ensure the hot side pressure drop index, most of the plate fin type channels are 6.5mm, the ventilation area of the heat sink is relatively small, the windward side is planar, the flow of the cold side wind is not facilitated, the wind resistance is large, the cooling fan rotates at high speed, large wind speed blows to the plane, cold wind fluid flows to both sides, the vertical wind speed of the outer fin is further influenced, and the turbulent flow corrugations of the outer fin cause the wind speed of the air outlet surface of the heat sink to be reduced, so that the heat dissipation performance of the heat sink is lost.

The trend of future development is to improve and optimize the structure of the parts of the radiator and improve the radiating efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an improve strip of paper used for sealing structure of plate fin radiator efficiency reaches and reduces cold side wind air inlet turbulent flow, improves the cold side ventilation air volume of radiator structure to improve heat radiation module's radiating efficiency.

The above technical purpose of the utility model is realized with following technical scheme: the sealing strip structure for improving the efficiency of the plate fin radiator comprises a plurality of plate fins which are arranged at intervals, wherein a channel for cold side air to circulate is formed between every two adjacent plate fins, each plate fin comprises two outer fins and an inner fin partition plate arranged between the two outer fins, the inner fin partition plate is positioned at one end, facing cold side air, of each plate fin, and a guide structure which facilitates the cold side air to flow into the channel between every two adjacent plate fins is arranged at one end, facing the cold side air, of the inner fin partition plate.

The utility model discloses a further set up to: the guide structure protrudes out of the outer fins, the cross section of the guide structure is arranged in a circular arc shape, and the guide structure and the inner fin partition plate are integrally formed.

The utility model discloses a further set up to: the guide structure protrudes out of the outer fin, the section of the guide structure is arranged in a taper shape, and the guide structure and the inner fin partition plate are integrally formed.

To sum up, the utility model discloses following beneficial effect has:

the structure can effectively reduce the wind resistance blowing to the side surface of the plate fin radiator, thereby ensuring that the maximum cooling air quantity passes through the radiator core under the minimum wind pressure, and improving the integral heat dissipation capacity of the heat dissipation module. In can also playing guide structure to a certain extent with the leading-in passageway of ventilating of less particulate matter, finally blow off the core, use for a long time improve before flat top formula structure strip of paper used for sealing radiator assembly and prevent stifled effect play the effect of certain degree. The radiator with the structure is matched with the fan electric control device, the work of the fan supplied by the engine to the radiating module can be reduced, and the saved energy is added to the engine to be output as working power.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the drawings and the specific embodiments.

The first embodiment is as follows: as shown in fig. 1, the sealing strip structure for improving efficiency of a plate fin radiator provided by the present invention comprises a plurality of plate fins 1 arranged at intervals, and a channel 2 for cold side air 6 to flow into is formed between two adjacent plate fins 1. Each plate fin 1 comprises two outer fins 3 which are parallel to each other, an inner fin partition plate 4 is fixedly installed between the two outer fins 3, the inner fin partition plate 4 is located on the end face, facing the cold side wind 6, of the plate fin 1, a guide structure 5 is arranged at one end, facing the cold side wind 6, of the inner fin partition plate 4, and the length direction of the guide structure 5 is arranged along the length direction of the inner fin partition plate 4.

The guide structure 5 is arranged in a circular arc shape and protrudes out of the outer tooth sheet, and the guide structure 5 and the inner fin partition plate 4 are integrally formed. The cold side wind 6 that will blow from the head-on carries out both sides along with circular arc shape guide structure 5 and shunts to passageway 2 in like this, blows out the radiator core outside along with the wind that blows into passageway 2, and this kind of structure can effectively reduce the windage of blowing at plate fin radiator side to guarantee to pass through the biggest wind speed under minimum wind pressure, guarantee that the biggest cooling amount of wind passes the radiator core, improve heat radiation module's whole heat-sinking capability. In can also playing guide structure 5 channel 2 with the leading-in ventilation of less particulate matter to a certain extent, finally blow off the core, use for a long time before improving flat top formula structure strip of paper used for sealing radiator assembly and play the effect of certain degree in preventing stifled effect. The radiator with the structure is matched with the fan electric control device, the work of the fan supplied by the engine to the radiating module can be reduced, and the saved energy is added to the engine to be output as working power.

The second embodiment is different from the first embodiment in that: as shown in FIG. 2, the guiding structure 5 is tapered in cross section and is integrally formed on the inner fin partition 4, and the ice sucker removing guiding structure 5 protrudes out of the outer fin 3. The cold side air 6 is blown to the rear of the guide structure 5 conveniently, so that the cold side air 6 flows into the channel 2 conveniently, and the circulation of the cold side air 6 is facilitated.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
