Problems solved by technology
[0002] During the normal operation of the car, various heat exchangers are inseparable. The radiator for the engine water jacket is to ensure that the engine is stable in a certain temperature range for a long time, and it can continue to work normally to maintain the highest working efficiency of the engine; The application of the supercharger is inseparable from the air charge cooler, that is, the intercooler (CAC). The matching use of the turbocharger and the intercooler increases the power per liter of the engine, reduces fuel consumption, and reduces emissions; With the development of automobiles, oil coolers are also used, some to dissipate heat for automatic transmissions, some for hydraulic systems, and some for retarders. These include EGR, car heater, car air conditioner evaporator, condenser, etc. Most of the above heat exchangers have the same problem, that is, the wall thickness of the main board or collector plate and the heat pipe is very different. Cause heat exchanger failure due to vibration, cold and heat shock, and pressure alternating shock, resulting in weak engine work, excessive emissions, increased fuel consumption, poor braking effect, and inability to switch multi-drive in time, etc., thus affecting normal work
In the existing conventional technology, there may often be a special fracture phenomenon that the main board or the cooling pipe near the collector plate is transversely fractured. This kind of failure is caused by the pressure stress or thermal stress that cannot be released in time. The thickness of the heat pipe is large, resulting in the failure of low-strength components at the junction of the part with high rigidity and the heat pipe with low rigidity
With the development of the automobile industry, the continuous improvement of the engine power per liter, the continuous increase of the working pressure of the engine cooling system, the widespread use of turbochargers, and the continuous improvement of the performance of the turbocharger system, the pressure and temperature of the system have also doubled. Trends, in order to meet the requirements of higher temperature and higher pressure, conventional heat exchangers cannot meet the needs of higher engines, which requires heat exchangers to upgrade materials and structures, although the application of high-strength materials and material thickness The increase of the engine can prolong the matching service time with the high-performance engine, but it will change the existing production process, add new tooling, molds and new equipment, thereby increasing investment and cost

The invention discloses a radiating pipe reinforced automobile heat exchanger. The radiating pipe includes a connecting pipe at one or both ends, an intermediate heat-dissipating pipe matched and connected with the connecting pipe, and a flow-disturbing inner fin inside the intermediate heat-radiating pipe. One end of the connecting pipe is placed The inside or outside of the middle heat dissipation pipe is connected with the middle heat dissipation pipe, and the other end of the connection pipe is connected with the main board. The wall thickness of the connection pipe is at least thicker than the thickness of the middle heat dissipation pipe, and the weakest part of the heat exchanger is partially strengthened. The overall structural strength of the heat exchanger is improved.
