Hello, everyone, today we are going to discuss the car radiator, understand the principle of the car radiator!
First of all, the car radiator is composed of three parts: water inlet chamber, water outlet chamber, main piece and radiator core. The coolant flows inside the radiator core and the air passes outside the radiator. The hot coolant cools as it dissipates heat to the air, and the cold air heats up as it absorbs heat from the coolant.
By Category:
According to the direction of coolant flow in the radiator, the radiator can be divided into longitudinal flow and transverse flow.
According to the structure of the radiator core, the radiator can be divided into tube type radiator core, tube type radiator core and plate type radiator core.
The function of car radiator is:
Protect the car from damage and keep the engine in the proper temperature range. The radiator belongs to the automobile cooling system. The radiator in the engine water cooling system consists of the water inlet chamber, the water outlet chamber, the main piece and the radiator core. The radiator uses water as a heat carrier to conduct heat through a large area of heat sink to dissipate heat in a convective way to maintain the appropriate operating temperature of the engine. The cleaning method of radiator is: 1, remove the bumper to find the position of the water tank; 2. Adjust the nozzle of the water gun into a spray, and adjust the pressure to the appropriate size to rinse towards the surface of the radiator; 3. Check whether the heat sink is damaged; 4. Install the bumper in the reverse order of disassembly.
Structure of automobile radiator:
Automobile radiator is an indispensable and important part of automobile water-cooled engine cooling system, which is developing in the direction of light weight, high efficiency and economy. Automobile radiator structure is also constantly adapting to new developments.
The core of the chip radiator is composed of many fine cooling tubes and heat sinks. Most of the cooling tubes are flat and circular sections to reduce air resistance and increase heat transfer area.
The core of the radiator should have enough flow area to allow the coolant to pass through, and should also have enough air flow area to allow sufficient air to pass through to take away the heat from the coolant to the radiator. At the same time, it must have sufficient heat dissipation area to complete the heat exchange between coolant, air and heat sink.
The pipe belt radiator is composed of corrugated scattered tropical and cooling pipe arranged by welding.
Compared with the tube chip radiator, the tube belt radiator can increase the heat dissipation area by about 12% under the same conditions. In addition, the heat dissipation belt opens a hole similar to the shutters with disturbed air flow to destroy the attachment layer of the flowing air on the surface of the scattered tropical zone and improve the heat dissipation capacity.
Maintenance and repair of automobile radiators:
Car radiator as a car internal heat transfer and heat conduction components, for the car plays an important role, the car radiator material is mainly aluminum or copper, radiator core is its main components, with coolant, generally speaking, car radiator is a heat exchanger. And for the maintenance and repair of the radiator, most owners are only a little understanding, let me introduce the maintenance and maintenance of the daily car radiator.
The radiator and the water tank together as the heat dissipation device of the car, in terms of its material, the metal is not corrosion resistant, so it should be avoided and acid and alkali and other corrosive solutions contact, so as not to be damaged. For automobile radiator, blockage is a very common fault, reduce the occurrence of blockage, it should be injected with soft water, hard water needs to soften after injection, so as not to produce scale caused by the blockage of automobile radiator. The weather is cold in winter, and the radiator is easy to freeze, so antifreeze should be added to avoid the freezing of water. In daily use, the water level should be checked at any time, and water should be added after cooling down. When adding water to the car radiator, the water tank cover should be opened slowly. The body of the owner and other operators should be as far away from the water inlet as possible, so as not to cause burns caused by the high pressure and high temperature oil and gas spout from the water inlet.
