Description

Automobile radiator

Technical Field

The utility model relates to the technical field of automobile heat dissipation, in particular to an automobile radiator.

Background

In the modern society, people are used as household automobiles as travel tools. The primary operation of the cooling system is to dissipate heat into the air to prevent overheating of the engine, but the cooling system has other important roles. Another important function of the cooling system is to warm up the engine as quickly as possible and keep it at a constant temperature. Fuel is continuously burned in automotive engines. The heat generated during combustion is largely removed from the exhaust system, but some heat remains in the engine, warming it up. When the temperature of the coolant is about 93 ℃, the engine reaches an optimal operating state. At this temperature the temperature of the combustion chamber is sufficient to completely evaporate the fuel, so that the fuel can be better burned and the gas emissions reduced.

The radiator is an important part in an automobile engine, most of radiators matched with saloon cars at home and abroad are aluminum radiators, and the radiator is mainly considered from the perspective of protecting the environment. In the european model car, the proportion of the aluminum radiator is 64% on average. From the development prospect of the production of automobile radiators in China, aluminum radiators produced by brazing are gradually increased.

The assembly structure of the core body in the prior art is shown in fig. 1 and comprises a main sheet, a radiating pipe, a radiating belt, a side plate and a water chamber, wherein the main sheet is made of AlMg alloy, and the internal organization structure of the main sheet is subjected to lattice change after the main sheet is brazed by a brazing furnace, so that a crack phenomenon can be generated. After the water chamber structure is matched with the sealing gasket and the core body is pressed, the sealing performance is very important. The core body sealing matching structure in the prior art is unreasonable, so that the quality of an intercooler product is reduced, and the leakage problem exists in the production process. And in the use process, the phenomenon of product leakage caused by unreasonable assembly of the water chamber and the sealing gasket is easy to occur. And can not bear certain pressure, and the water chamber is easy to be separated from the core body, thereby affecting the performance of the engine.

The disadvantages of the prior art core are summarized as follows:

1. the conventional core body is provided with a main sheet structure part, a main sheet structure die needs to be opened, and one part die needs to be additionally used;

2. when assembling, the left main piece and the right main piece are required to be assembled, and the assembling is complex;

3. the welding leakage risk is larger, and welding leakage scrapping is easily caused.
