Radiators for excavator is how to achieve heat dissipation?

- Mar 31, 2018 -

Heat Dissipation Method for Excavator Radiator: Hot water from the engine water jacket is divided into many small strands from top to bottom or horizontally and dissipates heat to the surrounding air. Increase the cooling area and accelerate the cooling of the water. After the cooling water passes through the radiator, its temperature will decrease by 10-15°C at this time. In order to take away the heat from the excavator radiator as quickly as possible, fans and radiators will be installed behind the radiator. working.

 

Excavator Radiator Cooling Strength Adjustment: The cooling intensity of a forced water cooling system is generally affected by engine speed, crankshaft speed, water pump and fan speed, and outside air temperature. When the conditions of use change, if the outside air temperature is high, the engine works under conditions of low speed and high load, and the cooling intensity is required to be strong, otherwise the engine is prone to overheating.

 

When the outside temperature is low and the engine load is not large, the cooling intensity should be weaker, otherwise the engine will become too cold. It is precisely because of this that to ensure that the engine works at the optimum temperature, there should be no overheating or undercooling, it must be able to automatically adjust the engine cooling intensity in accordance with changes in the conditions of use; on the cooling intensity adjustment method, first of all should change the flow After the excavator radiator air flow and flow rate, automatic fan clutch, shutters open and close; the second is to change the coolant flow and circulation line, thermostat open size, water pump.

 

Speaking of the basic performance of the radiators for excavator, it will be characterized by various temperatures and heat before and after the heat exchange between the air of the low temperature fluid and the water of the high temperature fluid.

 

It is the temperature of the air and water from the radiators for excavator inlet, the radiator's entire heat-dissipating area, the heat through rate, the temperature of each fluid (air, water) when the heat is absorbed by the air when the heat is received, the temperature after the water is exothermic, and The amount of heat released by the water (air's heat absorption) is determined. The amount of heat released and the required target temperature is not - it is the basis for determining the basic performance of the excavator radiator.
