Material and Design Requirements for Diesel Engine Radiator

- Mar 29, 2018 -

Diesel engine radiators, also known as engine water tanks, are key components of water-cooled engine cooling systems. When the diesel engine radiator is in use, it will cool the engine through forced water circulation. In this respect, we also need to pay attention to it as a heat exchange device that ensures the continuous operation of the engine in the normal temperature range.

 

When choosing a diesel engine radiator material, it is necessary to consider good heat transfer performance, strong corrosion resistance, sufficient strength, and good brazing performance, which means easy processing and economical efficiency.

 

According to the above requirements, the diesel engine radiator industry has been using copper and copper alloys as the main materials for manufacturing radiators. The material of the heat sink of the copper radiator is generally H90 brass tape. The thickness requirement is 0.01 to 0.20 mm. Tube piece radiator heat sink materials generally use H62, H68 brass band, the thickness requirement is 0.08 ~ 0.10 mm; pipe belt type radiator heat sink material commonly used T2, T3 copper belt, The thickness is 0.045-0.08 mm. However, in order to reduce the quality of the heat sink and reduce the cost, the material thickness of the heat sink is allowed to be 0.045 mm when the strength allows.

 

Afterwards, when it comes to the design requirements of the diesel engine radiator, it must be designed to meet the heat dissipation of the engine in the normal operating range. At the same time, the minimum space for vehicle installation requirements and the ease of maintenance should be taken into consideration.

 

In this regard, for the design of diesel engine radiators, it must be noted that the cooling capacity must be able to meet the needs of the engine under various operating conditions; the cooling system of the diesel engine radiator consumes less power , And heat fast; small size, light weight, convenient for our disassembly and maintenance; use more reliable, long life, low manufacturing costs.
