Analysis of Car Radiator and Its Improvement

Car water radiator analysis and improvement Whether it is to reduce the number of water tubes in the direction of the radiator core thickness, or reduce the geometry of the water pipe, the results will lead to a reduction of the cooling area, obviously affect the entire radiator cooling performance. In order to compensate for the loss of performance due to the reduction of the heat dissipation area, the only effective method is to develop a high-efficiency cooling belt. The louver-shaped zigzag radiating belt is a high-efficiency heat-dissipating element because the result of the local heat-emitting coefficient is improved after the incision is developed on the heat-transfer surface in the flow direction of the air flow. Polhausen explained the basic approach to increase the heat dissipation coefficient of the ribbed heat sink, applying this theory to various cuts formed at intervals. If the flow rate and physical parameters of the fluid are the same, the heat release coefficient is inversely proportional to the spacing of the incisions.

Japan's auto water radiator uses high-efficiency louver cooling ribs. Under the premise that the heat release coefficient is increased by 50%, the number of water pipes is reduced by half, the volume of the core is reduced by 50%, and the weight of the entire machine is also reduced to fully illustrate the high efficiency. The role of the cooling element. In Russia, cold-rolled ribbed tubes are widely used as heat exchange elements, which also solves the high-performance problems of heat exchangers on vehicles and ships.

When designing a water radiator for a vehicle, it is necessary to overcome the unmatched relationship between the heat dissipation amount and the weight of the cooling water pipe existing in the current water radiator. The development of high-efficiency air-side heat-dissipating components is the core and foundation for the development of a high-performance, compact, and compact vehicle water radiator, and an effective way to develop a new generation of main battle tank water radiators.
