Engine Cooling System

Function of engine cooling radiator

The heat taken from the engine is dissipated into the ambiance via the radiator.

BOM of radiator

Nb.# name material Temp dimension
1 header 3003 or 6061 O 1.5~3mm thickness
2 sideplate 3003 O 1~2mm thickness
3 tube 3003 H14
0.23~0.4mm thick
4 Fin 3003 H14~H18 0.07mm for ref.
5 Baffle(for multi-passes) 3003 H14 1.5~2mm
6 Gasket(for non full aluminum RAD ) EPDM / Ensure air tightness

Radiator dimension custom

Width & length of radiator core could be custom according to your original core.
Assembly brackets weld onto header according to your mounting points of frame.
Inlet and outlet pipes weld onto header according to your original radiator.
Draincock location designed to fit.
Tube pitch and fin pitch designed to have good heat dissipation.
Multi-passes are available to increase radiator heat transfer efficiency.
Thicker core is available to remove more heat from engine.

Technical information about radiator

Question 1
How much power is usually required for a radiator? For example, my car is a BMW 325i, and the maximum output power of the engine is 135kw.
Answer 1
Base on our experience, Radiators Cooling needs:
+ Engine power / 3
+ 4Kw for A/C models.
Then for BMW engine power of 135kw, considering A/C operation, you will need radiator power of 49Kw.
Question 2
Suddenly … engine temperature warning lights up. What ways help cooling up the engine?
Answer 2
Base on technical view and our understanding of coolant loop, below 3 ways are workable.

  • Turn off A/C (condenser is in front of the radiator and is heating up the air before it enters the radiator)
  • Turn on heating of the cabin (Heater core is an additionnal radiator in the engine cooling loop)
  • Lower the gear (increases the engine rate -> increase the flow rate in the engine cooling loop thanks to the mechanical pump related to engine rate)

Question 3

What kind of tests are performed during the OEM radiator developed?

Answer 3

Radiator is run for the following DV/PV tests: burst test for each braze oven, pressure cycle test, thermal cycle test, internal coolant corrosion test, external corrosion test, cleanliness test, thermal performance test, pressure drop test ect.
