Specific effects of various components in a diesel engine radiator

- Jun 08, 2018-

The radiator of a diesel engine is a key component of a water-cooled engine cooling system. It uses the cooling fluid to lose thermal energy to work. Cooling the engine through forced water circulation is a heat exchange device that ensures the continuous operation of the diesel engine in the normal temperature range.


The design of the diesel engine radiator is designed to meet the heat dissipation of the engine in the normal working range. At the same time, the minimum space for vehicle installation requirements and the ease of maintenance should be taken into consideration. Therefore, the entire device includes several components such as the upper water room, the lower water room, and the radiator core.


The upper part of the upper water chamber of the diesel engine radiator has a water inlet, and the cooling water is injected into the entire cooling system and covered with a radiator cap. In the upper water room and the lower water room, there are respectively an inlet pipe and a outlet pipe. The inlet pipe and the outlet pipe are respectively connected to the outlet pipe of the cylinder head and the inlet pipe of the water pump by the rubber hose, so that it is easy to install, and when the engine and the cooling When there is a small amount of displacement between the devices, no water leaks.


Under the radiator of a diesel engine, a cushion is generally installed to prevent the radiator from being damaged by the vibration. There is a water release switch on the outlet pipe of the radiator water room, and if necessary, the cooling water in the radiator can be released. For diesel engine radiators, the fan is designed to increase the air flow rate and flow through the radiator in order to enhance the radiator's ability to dissipate heat and cool engine accessories.


The role of the radiator cover in the diesel engine radiator is to close the water inlet to prevent the cooling night from spilling out; at the same time, the water vapor in the cooling system is also depressurized; in addition, the pressure in the cooling system can be balanced and the pressurization effect can be achieved. The core part of the entire diesel engine radiator is a radiator core, which plays a major role in heat dissipation.


The radiator core of a diesel engine radiator is composed of a heat pipe, a heat sink, and upper and lower main pieces. Since it has a sufficient heat dissipation area, it can ensure that necessary heat is dissipated from the engine to the surrounding atmosphere. Moreover, the radiator core is made of a very thin metal with good thermal conductivity and its alloy, so that the radiator core can achieve the highest heat dissipation effect with the smallest mass and size.
