Efficient integrated-type automobile radiator assembly structure

Abstract

The invention relates to an efficient integrated-type automobile radiator assembly structure. The efficient integrated-type automobile radiator assembly structure comprises a framework, an intercoolerand a radiator. The radiator comprises a radiator core, a water inlet chamber with a water inlet and a water outlet chamber with a water outlet. The radiator core is located between the water inlet chamber and the water outlet chamber and further comprises main blades, radiating pipes and a radiating belt. The intercooler and the radiator are arranged inside the framework in parallel. Flat pipesare adopted as the radiating pipes. Compared with the prior art, the arrangement mode of the intercooler and the radiator is changed into a side-by-side arrangement structure from an original front-back overlapping structure; however, the thickness is reduced, the heat radiating performance is improved, wind resistance is reduced, and space occupancy is decreased; by adoption of the flatter and wider radiating pipes, the laminar flow phenomenon of inner cooling liquid is reduced, and heat can be better transferred to the radiating belt from the pipe wall; and the water chambers are made of copper plates with the thicknesses being larger than 1mm, the flanging heights of the main blades and radiating pipe welding holes are increased, and the leakage condition of the four corners of the radiator can be effectively reduced.

Description

technical field [0001] The invention relates to the layout of the passenger car chassis and engine cooling system, in particular to a high-efficiency integrated car radiator assembly structure. Background technique [0002] With the advancement of passenger car technology, there are more and more domestic and foreign manufacturers of large, medium and small passenger cars, and the market competition is becoming more and more fierce. Under the pressure of market competition, how to keep the performance of the whole vehicle unchanged and reduce the manufacturing cost has become a topic that every bus factory pays more and more attention to. At present, the automobile engines of various companies are developing towards higher power. The performance of engines with the same displacement is continuously improved, and the heat generated is also greater. At the same time, my country’s requirements for automobile emission levels are becoming increasingly strict. To reduce emissions,...

Problems solved by technology

[0003] For all kinds of commercial vehicles and passenger vehicles currently on the market, the intercooler and radiator of the engine are generally arranged in a superimposed series. Assembly; due to the superposition of intercooler and radiator, the wind resistance is large, which is not conducive to the circulation of airflow, the heat dissipation effect is poor, the volume is large, and the space occupied is large, which is not conducive to the layout of front-engine models with small space; Conducive to the weight reduction and emission reduction of the whole vehicle, inconvenient disassembly and high after-sales maintenance cost

Chinese patent CN 105673187A discloses a parallel radiator assembly, including a frame, an intercooler mounted on a first area of ​​the frame, and a radiator mounted on a second area of ​​the frame, wherein, The intercooler and the radiator are arranged side by side on the same windward surface, but the installation of the radiator and the intercooler is not firm, not compact, and the sealing is not good

[0004] Most of the cooling liquid inside the radiator pipe in the existing automobile radiator assembly structure is laminar flow, which is not conducive to the heat transfer from the tube wall to the radiator belt, and the heat exchange efficiency is low; at the same time, due to material reasons, the radiator will also leak , resulting in heat exchange failure, and the radiator does not meet the lightweight design requirements
